Bar-none the easiest way to move in Belle Glade is to hire professionals to do the move for you. This is the certain way to correctly finish the job. Even when you use this method there are still more steps you can take to make an easier move.
Lots of people assume if they are only moving a short distance in Belle Glade , they can automatically move the contents of their house to their new home. Size differences between your new home and old may make this impractical anyway, but it is probably not a good choice either way.
After all, you will entrust your belongings in the hands of strangers, so you need to, at least, make sure they are experienced professional movers. So, the best way to establish if a moving company will take good care of your belongings, during the moving process, is to ask the right questions, at the right time. The right time is always before hiring them. This will help you save time and money! 1. Does your company have the necessary licenses?This is a common sense question and the first to ask any moving company you're considering to hire for your move. Professional moving companies usually mention their licenses on their website and, if you visit their location, you will be able to see their certificates on various walls. However, if you don't have access to evidence that they are licensed, you should ask a representative of the company about this during your first conversation with them. Any professional moving company has to be a member of the American Mover and Storage Association, which guarantees that their company respects the necessary federal laws, as well as of the Better Business Bureau, a membership that proves their reliability. A moving company that offers cross country moving services has to have an USDOT number issued by the Federal Motor Carrier Safety Administration (FMCSA). You can easily check for this number online and see if the company has the USDOT. 2. What services do you offer?It's important to know all the services that a moving company offers. The smaller moving companies might not have the necessary equipment to move voluminous or heavy items, such as pianos or pieces of furniture that can't be disassembled. Some companies may provide disassembling and assembling services, which are useful if you have a lot of furniture to move to a different location. There are moving companies that also offer packing and unpacking services, very helpful for all types of moves, but these are usually available for extra cost. It's important to know all the services the moving company is offering, whether we're talking about packing and unpacking, disassembling and assembling, loading and unloading and so on. This way you can be sure you will get all the services you need for a successful and stress-free move. 3. Do you have an arbitration program?An arbitration program is very useful in case the customers raise claims against moving companies and these can't be settle amicably. Instead of going to court and wasting a lot of time and money, the arbitration company that collaborates with the moving company will give you access to an easy and fast way to settle the dispute. An arbitration company is also very useful for the moving company because they will help them respect all the rules and regulations imposed by the FMCSA. The FMCSA actually require the moving companies to have an arbitration program in place. 4. Do you give written estimates?Some moving companies give estimates regarding moving costs by phone or email. However, you need to know that this is never enough! If you want to make sure you know the exact price you're going to pay for the move, you need to request a written estimate which won't have to exceed the price you've discussed initially. If you have a written estimate, your move will be protected by the Washington Utilities and Transportation Commission, which means that you won't have to pay more than 25% over your estimate. The best way to get a correct estimate is to make sure you give the movers accurate information about the move, such as the distance the moving trucks will have to cross to get to the destination, as well as the number of men and trucks you need. It will also help to know what payment methods they accept and how much will extra services cost. 5. How will you be handling my items?It's very important to know how the movers will handle your items, especially if you have antique pieces of furniture or other valuable belongings. The movers will also have to protect the interior of both your former and new home when moving your things. They should use all types of accessories to protect the floors, walls, corners and door frames, like moving blankets, carpet films, corner guards, and foam. The moving company should work only with experienced movers, who really know what they are doing and how to bring everything in one piece to the destination. It's useful for the movers to come in advance and measure doorways, turns, elevators and stairways, so they can be prepared for the moving process.
We all know about the big moving companies. Their ads are all over the place including on the page that this article is published. There is absolutely nothing wrong with these national and even world movers. If you need to save money on your next move please consider hiring small movers. Three Great Reasons to Choose Small Movers Small movers are not going to be the right thing for all moves. You really need to be moving within a fairly small geographical area to use these small companies. Most of them specialize in local moves. If your move can be driven in a few hours or less then I have three great reasons to hire small movers while you are moving cheap. Small Movers Tend to be Reliable Reliability is a really good reason to use small movers. These companies rely on a good reputation and word of mouth for business. We are talking about small companies that are often three guys and a truck. They don't have huge budgets for big advertising campaigns. If you live in a small enough town you might even know the small movers personally, or you might know someone that knows them. They might not want to disappoint whoever recommended them to you. Small Movers Should Give you Great Service Because they are small and need all of the free advertising they can get from happy customers you should be getting wonderful customer service. The difference between professional and armature movers is how many moves they have been paid to make. Anyone can be careful or be way to rough with your belongings; it depends on how much they care. If you are dealing with the boss then they will care. Also the employees might be used to getting a tip when they do a good job. Negotiate a Good Deal We don't try to haggle nearly enough in the United States. A large part of that is because we are used to all of the huge multi national companies with there rigid rules that the employees are not allowed to make deals. Which is why this is the third reason to try small movers when you are moving cheap. Employees in small businesses are often allowed and even encouraged to use the brain that god gave them to make a deal. Don't be afraid to ask and then ask some more. See what they will give you if they really need your money, and of course you're going to tell everyone how happy you were with their service. Best Way to Find Them So, where are all of these wonderful small moving companies anyway? The very best way to find them is by word of mouth. Ask your friends and family if they have had any good experiences with a particular group. If that is not going to work then go to the local collage and check any postings or message boards. If that isn't what you want to do or it is just to time consuming then try the yellow pages and of course the internet. Just make sure their company is bonded and make sure you feel good about the conversation you have with their representative on the phone. Ask questions and make sure all of your concerns have been answered. Don't just book and pay for a move online on a site you know nothing about. Look for a phone number and pay cash when the job is done. Lastly you will need to stick around and keep an eye on things and don't be afraid to just fire them if you are not happy.

Actor Tunisha Sharma's Death Matter Of "Love Jihad", Says Maharashtra Minister
A senior cop said as of now there's no angle of "love jihad in this case.
Nashik:
Maharashtra Minister and BJP leader Girish Mahajan on Sunday claimed that the death of actor Tunisha Sharma is a matter of "love jihad" and the state police are investigating the case.
The minister also stressed that the Eknath Shinde government in the state is mulling bringing a strict law against "love jihad".
This comes a day after Tunisha Sharma allegedly died by suicide on the sets of her show.
Speaking to ANI, Mr Mahajan said, "It is a matter of 'love jihad' and police are investigating the case. We are seeing that such cases are increasing day by day and we are mulling bringing a strict law against it".
However, Assistant Commissioner of Police (ACP) Chandrakant Jadhav said that there is no angle of any other affair, blackmailing or "Love Jihad", as of now.
"The investigation is underway. Accused Sheezan's and the victim's phones have been seized. There is no angle of any other affair, blackmailing or "Love Jihad", as of now," he said.
Earlier today, police said the reason behind Tunisha's alleged extreme step was her breakup with co-star Sheezan Mohammed Khan over a fortnight back.
A case of abetment to suicide was registered against Sheezan under Section 306 of the Indian Penal Code, after his 'Ali Baba: Dastaan-E-Kabul' co-star was found dead on the set.
Sheezan was taken by the officials from Waliv police station to the Vasai court on Sunday.
At the court, Sheezan's lawyer, Sharad Rai, spoke to the media saying, "He (Sheezan Khan) was been produced in court. Allegations against him are baseless."
The Waliv Police on Sunday said the post-mortem report of the actor specified 'hanging' as the cause of death.
Meanwhile, police recorded statements of 14 people, so far, in connection with the Tunisha Sharma death case.
"Tunisha Sharma used to work as an actress in a TV show. Tunisha and Sheezan Khan had an affair. They had a break-up 15 days ago after which she died by suicide on the sets of her show," Assistant Commissioner of Police (ACP) Chandrakant Jadhav said during a press conference.
The ACP further said, "Tunisha's mother had filed a complaint and the accused, Sheezan, was arrested and later produced in court which sent him to four-day judicial custody. The post-mortem report clearly specifies the cause of death as hanging."
Tunisha's body was brought to the JJ Hospital, Naigaon around 1.30 am on Sunday where her post-mortem was conducted.
Tunisha's last rites will be performed on December 27 in Mumbai's Mira road area, her maternal uncle Pawan Sharma told ANI.

Q: Question regarding nullity and basis of a kernel I was doing some exercises in a textbook and it required that I find the nullity of a linear transform. That I know how to do and you it by finding the kernel of that linear transform. It then asked to find a basis for that kernel of T. I was confused and noticed that the solution stated the same matrix that I used to find the nullity of T. My question is how is finding the nullity of T related to, or equivalent, to find a basis for the kernel of T?

A: The nullity is the dimension of the kernel and hence equal to however many vectors are in a basis for the kernel.

Bernardo Daddi (h. 1280 - 1348) va ser un pintor gòtic italià i aprenent de Giotto di Bondone. Li va influir també l'art sienès de Pietro Lorenzetti.

La data de naixement de Daddi és desconeguda. Se l'esmenta per primera vegada el 1312. Es va centrar en motius religiosos i altars. Un tríptic que va pintar el 1328 es troba en els Uffizi, i hi ha diversos panells a la National Gallery of Art i el Walters Art Museum de Baltimore.

Daddi es va convertir en el pintor més destacat de Florència de la seva generació. La seva última obra data de l'any 1347, i es creu que va morir a l'any següent.

Q: How does the MVVM pattern work for validating data? I have started using the MVVM pattern.
Everything is fine if I want to display data, I can just find the item source to a object and everything displays as it should.
My question is how do I validate input data? E.g. I have 2 input fields and I need to ensure the fields are populated and ensure the item does not already exist.
Can I just forward the content of the fields to my view model or is there a different/better way?

A: Your ViewModel should implement IDataErrorInfo to do validation.
Example code in C#:
public class EmployeeViewModel : IDataErrorInfo, INotifyPropertyChanged
{
    public string FirstName { /* get set and NotifyChanged here...*/ }

    public string LastName { /* get set and NotifyChanged here...*/ }

    public string Error
    {
        get { return error; }
    }

    public string this[string columnName]
    {
        get
        {
            string error = string.Empty;
            switch (columnName)
            {
                case "FirstName":
                    if(string.IsNullOrEmpty(this.FirstName))
                        error = "FirstName can not be blank";
                    else if (this.FirstName == "Ekk")
                        error = "Ekk is my name, you should change!";
                    break;
                case "LastName":
                    if(string.IsNullOrEmpty(this.LastName))
                        error = "LastName can not be blank";
                    break;
            }
            return error;
        }
    }
}


Deepika Padukone spills the beans on her relationship with Ranveer Singh and the upcoming #DeepVeer wedding!
Well, with that news settling in, now the speculations are rife from where and who will Deepika wear for her D-day. Well duh-huh Sabyasachi!
Deepika said she loves Ranveer's "emotional quotient", hate's his lifestyle ("sleeping hours and all") and she tolerates his "fashion sense".
Deepika confirmed that she's been dating Ranveer Singh for six years. It was KJo who asked, "How long have you been dating Ranveer... five years?" Deepika mouthed, "Six."
It seems that Deepika and Ranveer's B-town colleagues are not invited to the main ceremony. In one segment, while speaking about "the ceremony," Alia said, 'Are we invited?" and Karan Johar said, 'No. We are not invited'."
From what it looks like, #DeepVeer have restricted the guest list to family members and close friends only!
Also, while many celebs congratulated the lovely couple, it was Priyanka Chopra's reaction (which arrived a little late as she is in the US) stood out.
Well after all of this, I literally can't contain my excitement for this wedding!

As a tipsy horde dances and roaring guitar fills the musty basement at deafening volumes, photographer Matt Jaskulski crouches and waves his camera around. He's trying to snap the perfect shot.
Jaskulski, 33, moved from Spain to Bloomington in December 2017. Since then, he's become a recognizable fixture of the local music scene, photographing bands at venues around town.
Bloomington's music scene is known for house shows, DIY performances often in the basements of cheekily named houses like the Rat House or Mosquito Mansion that host mostly local bands. Tangles of colored lights hang from basement ceilings, strange paintings adorn the walls and concertgoers, party animals and local music nerds alike pack into the basement. Sometimes, the shows are so loud that bowls of earplugs sit at the ready.
And usually, Jaskulski is there, camera in hand.
Jaskulski's friend brought him to his first house show, a performance at Rat House. He happened to have his gear on hand because of a shoot earlier in the day, and he decided to take photos of the show.
After that first house show, audience members and performers already began to notice him. He uploaded his photos right away, and at a house show the next night he received a slew of compliments on his work.
Bryce Greene, a member of the band Strange Implications, said Jaskulski always captures the energy and emotion of the performances he shoots.
Jaskulski's passion shows in all of his work, Bryce Greene said.
"I imagine he just adores doing the job he's doing," he said.
Jaskulski's love of photography began when he explored web design as a hobby while in graduate school at the Wrocław University of Science and Technology in Poland.
Because he wasn't exceptionally skilled at drawing, photography was a sort of work around for incorporating the elements he wanted into his designs. Eventually, he stopped doing web design but his interest in photography stuck.
That interest grew through the rest of his time in graduate school, where he received three degrees in science and engineering. Jaskulski also earned his Ph.D. at the University of Murcia in the south of Spain, studying physiological optics.
Jaskulski moved to Bloomington for IU's School of Optometry, where he works in physiological optics, which he explains as "the physiology of how we see." Through his job, Jaskulski works on writing software that can analyze data from human eyes to simulate how a person sees.
To Jaskulski, his scientific work and his photography aren't that different. Eyes are like cameras, he said, and vice versa.
"Both photography and human vision, you can appreciate how those two worlds are similar," he said.
Several times already, Jaskulski said, he's encountered opportunities where he could have taken his photography in a professional direction. He's tried to work with photo agencies, but that would take him down a road toward fashion and beauty photography, away from the joy of shooting Bloomington house shows.
For Jaskulski, part of the fun is in the experimentation. He loves the energy of house show venues and performers, and he wants to channel that into his photography.
He also favors the immediacy of close-ups to shooting from farther away – it's why he likes the intimacy of house shows far more than the scale of standard concerts, and it's also why he'll generally crouch on the floor between the performers and their audience.
He crouches to avoid obscuring people's views, and to get a variety of angles he extends his arms up over the fray to get the perfect angle but not ruin the view for others.
Doing that requires an awareness, he says. It's important that he knows his camera settings and the focal length of his lens, so that when he thrusts his camera above the crowd he can still envision what it will see. He prefocuses the camera and knows its approximate depth of focus.
He rocks it back and forth so that he'll have a finely focused shot in at least one of the final images.
Much of it is more developed instinct than careful planning, he said.
Rob Greene, a member of the band Secret Mezzanine, said he first noticed Jaskulski at a show at the Brick House a couple of months ago. Since then, Rob Greene, unrelated to Bryce, said that Jaskulski has become as much of a fixture of the house show scene as the bands themselves.

\section{Introduction}

\noindent
Electromagnetic knots were first developed in 1989 by Rañada \cite{Ranada89} using the Hopf map. These knots are finite-action vacuum solutions of Maxwell's equations that consist of rational functions in the spacetime coordinates. In the original construction, two complex scalar fields $\phi$ and $\theta$ are used, and their level curves coincide with the electric and magnetic field lines. Those fields can be seen as maps from $S^3 \times \mathds R$ to $S^2$, where $S^3$ here is the compactified three-dimensional space $\mathds R^3 \cup \{\infty\}$ and $S^2$ is the compactified complex plane $\mathbb{C} \cup \{\infty\}$. The solutions are characterized by a topological invariant, the so-called Hopf index. Since then, other approaches were developed to construct electromagnetic knot solutions, for example using the twistor theory developed by Penrose, complex Euler potentials, or special conformal transformations; see \cite{Arrayas17} for a comprehensive review. Knotted electromagnetic fields might become important for future applications for their unique characteristics. Therefore, it is important to seek experimental settings to generate those fields and to study scenarios with them. Irvine and Bouwmeester \cite{Irvine08} discuss the generation of knotted fields using Laguerre--Gaussian beams and predict potential applications in atomic particle trapping, the manipulation of cold atomic ensembles, helicity injection for plasma confinement, and in the generation of soliton-like solutions in a nonlinear medium. Laser beams with knotted polarization singularities were recently used to produce some simple knotted field configurations including the figure-8 knot in the lab \cite{LSMetal18}.

Lately, a new method \cite{OlafZhilin18} has been developed for deriving a complete basis of electromagnetic knotted solutions to Maxwell's equations. This was achieved by utilizing the conformal invariance of four-dimensional Maxwell theory and a conformal equivalence of half of de Sitter space dS$_4$ to the future part of Minkowski space $\mathds R^{1,3}$. More explicitly, one utilizes a manifest SO($4$)-covariant formalism on the spatial three-sphere slices of dS$_4$ to obtain analytic solutions of Maxwell's equations in terms of hyperspherical harmonics, which can easily be mapped onto Minkowski space with an explicit conformal map. This method also reproduces the aforementioned Hopf--Rañada knot as a simple case. Several features of the electromagnetic fields constructed via this new method have been explored, such as fall-off behavior, asymptotic energy flow, null solutions, and conserved helicity and conformal charges \cite{KL20,KaushalGabriel21}. To seek experimental applications, however, it is essential to elucidate the behavior of charged particles in the background of these fields.

The objective of this paper is to study the behavior of classical point charges in the knotted electromagnetic fields obtained via the ``de Sitter method''. We first review the spacetime correspondences used in the method, followed by the construction of the field configurations and a discussion of their properties with the help of illustrative figures of field lines and energy densities in Section \ref{sec2:fields}. Afterwards, in Section \ref{sec3:trajectories} we numerically solve the Lorentz force equation for relativistic classical charged particles subject to these fields in different settings and try to unravel the impact of various parameters on the trajectories of the particles.

\section{The construction of knotted electromagnetic fields}\label{sec2:fields}

\subsection{The ``de Sitter method"}

Four-dimensional de Sitter space $\mathrm{d}{S}_4$ can be described as a hypersurface embedded in $\mathds R^{1,4}$ and defined by the constraint
\begin{equation}\label{hyperbol}
	-q_0^2+q_1^2+q_2^2+q_3^2+q_4^2 \= \ell^2\ ,
\end{equation}
that is, a single-sheeted hyperboloid in $\mathds R^{1,4}$, where the $q$'s are standard coordinates in the 5-dimensional Minkowski space, and $\ell$ is the so-called ``de Sitter radius''. We can parametrize dS$_4$ using
\begin{equation}
	q_0 \= -\ell \cot \tau \quad\textrm{and}\quad q_{_A} \= \frac{\ell}{\sin \tau} \omega_{_A} \quad\textrm{for}\quad A = 1,2,3,4\ ,
\end{equation}
with $\tau \in {\cal I} := (0,\pi)$ and $\omega_{_A}$ being coordinates of $\mathds R^4$ embedding the unit three-sphere $S^3$ via $\omega_{_A} \omega_{_A} = 1$. The standard Minkowski metric on $\mathds R^{1,4}$ then induces on d$S_4$ the metric
\begin{equation}
	\mathrm{d}{s}^2 \= \frac{\ell^2}{\sin^2 \tau} \( -\text{d}\tau^2 + \text{d}\Omega^2_3 \)\ ,
\end{equation}
where $\text{d}\Omega^2_3$ is the round metric on the unit $S^3$. It is then clear that de Sitter space $\mathrm{d}{S}_4$ is conformally equivalent to a cylinder ${\cal I} {\times} S^3$. We proceed to map part of the cylinder to the future half of four-dimensional Minkowski space $\mathds R^{1,3}$ with
\begin{equation}\label{eq:coordinates}
	-\cot \tau \= \frac{t^2-r^2-\ell^2}{2\ell t}, \quad \omega_1 \= \sigma \frac{x}{\ell}, \quad \omega_2 \= \sigma \frac{y}{\ell}, \quad \omega_3 \= \sigma \frac{z}{\ell}, \quad \omega_4 \= \sigma \frac{r^2-t^2-\ell^2}{2\ell^2}\ ,
\end{equation}
where $x, y, z \in \mathds R, t \in \mathds R_+, r^2 = x^2+y^2+z^2$ and
\begin{equation}\label{eq:gamma}
	\sigma \= \frac{2\ell^2}{\sqrt{2\ell^2t^2+(r^2-t^2+\ell^2)^2}}\ .
\end{equation}
We can glue together two copies of the cylinder by taking $\tau \in 2{\cal I} := (-\pi,\pi)$ to cover the entire Minkowski space. If one expresses the metric in the $(t,x,y,z)$ coordinates one obtains
\begin{equation}
	\text{ds}^2 \= \frac{\ell^2}{t^2}\left(-\mathrm{d}{t}^2 + \mathrm{d}{x}^2 + \mathrm{d}{y}^2 + \mathrm{d}{z}^2\right)\ ,
\end{equation}
which shows the conformal equivalence between part of $2{\cal I} {\times} S^3$ and $\mathds R^{1,3}$. For more details, see \cite{OlafZhilin18}.

Now we proceed to the construction of the Maxwell solutions. The fact that Maxwell's equations (or, more generally, the Yang--Mills equations) are conformally invariant in four dimensions allows one to solve them in any other four-dimensional spacetime that is conformally related to the desired spacetime. In particular, here we will get a basis of solutions on the Minkowski space by solving the equations on the cylinder over the three-sphere. This lets us take advantage of a SO($4$)-covariant formalism. Moreover, since $S^3$ is the group manifold of SU$(2)$, one can also parametrize the spatial part of the cylinder by the group elements of SU($2$).

Using the Maurer--Cartan prescription one obtains three anholonomic one-forms $e^a(\omega)$, with $a \in \{1,2,3\}$ and $\omega$ representing the embedding coordinates of the three-sphere. They can be computed using the self-dual 't Hooft symbol $\eta^a_{_{\ BC}}$:
\begin{equation}\label{eq:one-form}
    e^a \= -\eta^a_{_{\ BC}}\, \omega_{_B}\, \mathrm{d} \omega_{_C} \quad\textrm{with}\quad \eta^a_{\ bc} \= \varepsilon_{abc} \quad\textrm{and}\quad \eta^a_{\ b4} \= -\eta^a_{\ 4b} \= \delta^a_b\ .
\end{equation}
These one-forms satisfy the Maurer--Cartan equations and diagonalize the three-sphere metric, i.e.,
\begin{equation}\label{eq:maurercartan}
	\mathrm{d}{e}^{a} + \epsilon_{abc}\,e^b\wedge e^c \= 0 \qquad \text{and} \qquad e^{a}\,e^{a} \= \text{d}\Omega^2_3\ .
\end{equation}
Let $\mathrm{d}{\tau}$ be the one-form associated with the temporal coordinate on the cylinder. One can then expand the gauge connection one-form ${\cal A}$ on the cylinder as
\begin{equation}
	{\cal A}(\tau,\omega) \= X_\tau(\tau,\omega)\,\mathrm{d}{\tau} + X_a(\tau,\omega)\,e^a\ ,
\end{equation}
where $X_\tau$ and $X_a$ are real functions on the cylinder. Using the temporal gauge-fixing condition, $X_\tau=0$, this simplifies to
\begin{equation}
	{\cal A}(\tau,\omega) \= X_a(\tau,\omega)\,e^a\ .
\end{equation}

Now, as mentioned before, we take advantage of the fact that we are working in $S^3$ to employ a SO($4$)-covariant formalism. The universal covering group of SO($4$) is Spin($4$), which is equivalent to SU($2$)$_L\times$SU($2$)$_R$, where $L$ and $R$ stand for left and right. We can then use this structure to decompose the spatial dependence of functions on the cylinder using the hyperspherical harmonics $Y_{j;m,n}(\omega)$ (also called left-right harmonics). For an explicit construction using the three-sphere coordinates, see \cite{OlafZhilin18}. Take $I_a$ and $J_a$ to be the generators of the two (left and right, respectively) $\mathfrak{su}(2)$ subalgebras, with
\begin{equation}
	[I_a, I_b] \= \mathrm{i}\, \epsilon_{abc} I_c, \quad [J_a, J_b] \= \mathrm{i}\, \epsilon_{abc} J_c \quad\textrm{and}\quad [I_a, J_b] \= 0\ .
\end{equation}
They act on the hyperspherical harmonics as
\begin{equation}
	I_3\, Y_{j;m,n} = m\,Y_{j;m,n}, \quad J_3\, Y_{j;m,n} = n\, Y_{j;m,n}, \quad\textrm{and}\quad I^2\, Y_{j;m,n} = J^2 \, Y_{j;m,n} = j(j{+}1)\,Y_{j;m,n}\ ,
\end{equation}
with $I^2 := I_a I_a$ and $J^2 := J_a J_a$ being the Casimirs of the two $\mathfrak{su}(2)$ subalgebras.

On top of the temporal gauge, we can further impose the Coulomb gauge condition
\begin{equation}
	J_a\, X_a(\tau,\omega) \= 0\ .
\end{equation}
Moreover, the Maxwell equations $\mathrm{d}{*{\cal F}}=0$, with ${\cal F}:=\mathrm{d}{{\cal A}}$ read, in this setting,
\begin{equation}
	-\tfrac{1}{4} \partial_\tau^2 X_a \= (J^2 {+} 1) X_a + \text{i}\, \epsilon_{abc} J_b X_c\ .
\end{equation}

One can then expand
\begin{equation}
	X_a(\tau,\omega) \= \sum_{j=0}^{\infty}\, \sum_{m,n=-j}^{j} Z_a^{j;m,n}(\tau)\, Y_{j;m,n}(\omega)
\end{equation}
to transform the gauge-fixing condition and the Maxwell equations into matrix equations diagonal in $j$ and $m$. Using $X_\pm(\tau,\omega) := X_1(\tau,\omega)\, \pm\, \text{i}\, X_2(\tau,\omega)$, the matrix equations can be decoupled and easily solved to find a full basis of solutions to the system of equations,
\begin{align}\label{eq:solutionsX}
	&X_+^{(j;m,n)}(\tau,\omega) \= \sqrt{(j-n)(j-n+1)/2}\; \text{e}^{\pm 2(j+1)\text{i} \tau}\, Y_{j;m,n+1}(\omega)\ ,\nonumber\\
	&X_3^{(j;m,n)}(\tau,\omega) \= \sqrt{(j+1)^2-n^2}\; \text{e}^{\pm 2(j+1)\text{i} \tau}\, Y_{j;m,n}(\omega)\ ,\\
	&X_-^{(j;m,n)}(\tau,\omega) \= -\sqrt{(j+n)(j+n+1)/2}\; \text{e}^{\pm 2(j+1)\text{i} \tau}\, Y_{j;m,n-1}(\omega)\ ,\nonumber
\end{align}
where $j\geq 0$, $m$ ranges from $-j$ to $j$, $n$ ranges from $-(j{+}1)$ to $j{+}1$ and it is understood that $Y_{j;m,n}$ vanishes for $|n|>j$.

Now one can proceed to find the electromagnetic fields using
\begin{equation}\label{eq:fieldfromA}
	{\cal F} \= \mathrm{d}{{\cal A}} \= \partial_\tau\,{\cal A}_a \mathrm{d}{\tau}\wedge e^{a} + \left(\tfrac{1}{2}R_{[b}{\cal A}_{c]}-{\cal A}_a \epsilon_{abc}\right) e^b \wedge e^c\ ,
\end{equation}
and the electric and magnetic field on the cylinder will have components ${\cal E}_a = {\cal F}_{a\tau}$ and ${\cal B}_a = \tfrac{1}{2}\epsilon_{abc}{\cal F}_{bc}$, respectively.

\subsection{Electromagnetic knots in Minkowski space}

To find the corresponding electromagnetic fields in Minkowski space, one has to write the one-forms $\text{d} \tau$ and $e^{a}$ in terms of $\text{d} x^\mu$. A straightforward but somewhat bulky computation using \eqref{eq:coordinates}, \eqref{eq:gamma} and \eqref{eq:one-form} gives these one-forms in terms of spacetime coordinates $(t,{\bf x})$:
\begin{align}
	\mathrm{d}{\tau} &\= \frac{\sigma^2}{\ell^3} \left( \tfrac{1}{2}(t^2+r^2+\ell^2)\,\text{d} t - t\, x^k \text{d} x^k \right) \qquad \text{and}\\
	e^{a} &\= \frac{\sigma^2}{\ell^3} \left[ t\, x^{a} \text{d} t - \left(\tfrac{1}{2}(t^2-r^2+\ell^2) \delta^{ak} + x^{a} x^{k} + \ell\, \epsilon_{ajk} x^j \right) \text{d} x^k \right]\ .
\end{align}
Substituting into (\ref{eq:fieldfromA}), one gets $F_{\mu \nu}$ of ${\cal F} = \tfrac{1}{2}F_{\mu\nu}\, \text{d} x^\mu\, \text{d} x^\nu$, with $\text{d} x^0 = \text{d} t$, and obtains the components $E_i = F_{0i}$ and $B_i = \tfrac{1}{2} \epsilon_{ijk}F_{jk}$ of the electric and magnetic fields in Minkowski space for any configuration generated by the basis (\ref{eq:solutionsX}). Since the basis configurations \eqref{eq:solutionsX} are complex, the basis configurations on Minkowski space will also be complex. Hence, they combine two physical solutions, namely the real and imaginary parts, which we denote as
\begin{equation*}
    (j;m,n)_R~ \textrm{configuration} \quad\textrm{and}\quad (j;m,n)_I ~\textrm{configuration}\ ,
\end{equation*}
respectively. The basis configurations increase in complexity with increasing $j$, as shown in Figure \ref{fieldLines}. Furthermore, they have a preferred $z$-axis direction which is clearly exemplified in Figure \ref{EnDen}, where the energy density $E := \sfrac12 ({\bf E}^2 + {\bf B}^2)$ decreases along the $z$-axis. As a result, the basis fields along the $z$-axis (i.e. ${\bf E}(t,x{=}0,y{=}0,z)$ and ${\bf B}(t,x{=}0,y{=}0,z)$) are either directed in the $xy$-plane or along the $z$-axis. In fact, for extreme field configurations $(j;\pm j,\pm (j{+}1))$, for any $j{>}0$, the fields along the $z$-axis vanish for all times. In the simulations we have also used the maximum of the energy density at time $t$, i.e. $E_{max}(t)$ (that occurs at several points ${\bf x}_{max}$ that are located symmetrically with respect to the origin), for different initial conditions and field configurations, and in each case we have employed a parameter $R_{max}(t)$ of ``maximal'' radius defined via
\begin{equation}\label{Rmax}
    E\left( t,{\bf x}_{max}(t) \right) \= E_{max}(t)\quad \implies \quad R_{max}(t)\ :=\ |{\bf x}_{max}(t)|\ .
\end{equation}

As previously stated, the celebrated Hopf--Rañada knot is an example of electromagnetic knotted field that can be generated by these Minkowski electromagnetic fields (more precisely, a linear combination of $j{=}0$ configurations) \cite{OlafZhilin18}, as are generalizations such as the time-translated Hopfian and the rotated Hopfian \cite{KaushalGabriel21}.

\section{Trajectories}\label{sec3:trajectories}

Given a knotted electromagnetic field configuration, a natural issue that arises is the behavior of charged particles in the background of such a field. We proceed to address this issue by analyzing, with numerical simulations, the trajectories of several (identical) charged point particles for the family of knotted field configurations that we encountered in the last section. We will mostly consider basis field configurations (up to $j{=}1$ for simplicity) except for the Hopf--Rañada field as previously discussed.

The trajectories of these particles are governed by the relativistic Lorentz equation
\begin{equation}\label{eq:force1}
	\frac{\text{d} {\bf p}}{\text{d} t} = q({\bf E}_{\ell}+{\bf v} \times {\bf B}_{\ell})\ ,
\end{equation}
where $q$ is the charge of the particle, ${\bf p} = \gamma m {\bf v}$ is the relativistic three-momentum, ${\bf v}$ is the usual three-velocity of the particle, $m$ is its mass, $\gamma = (1-{\bf v}^{\,2})^{-1/2}$ is the Lorentz factor, and ${\bf E}_{\ell}$ and ${\bf B}_{\ell}$ are dimensionful electric and magnetic fields respectively. With the energy of the particle $E_{p} = \gamma m$ and $\text{d} E_p/ \text{d} t = q\, {\bf v} \cdot {\bf E}$, one can rewrite (\ref{eq:force1}) in terms of the derivative of ${\bf v}$ \cite{landau2} as
\begin{equation}\label{eq:force2}
	\frac{\text{d} {\bf v}}{\text{d} t} = \frac{q}{\gamma m} \left( {\bf E}_{\ell} + {\bf v} \times {\bf B}_{\ell} - ({\bf v} \cdot {\bf E}_{\ell})\,{\bf v} \right)\ .
\end{equation}
Equations (\ref{eq:force1}) and (\ref{eq:force2}) are equivalent, and either one can be used for a simulation purpose; they only differ by the position of the nonlinearity in ${\bf v}$. In natural units $\hbar {=} c {=} \epsilon_0 {=} 1$, every dimensionful quantity can be written in terms of a length scale. We relate all dimensionful quantities to the de Sitter radius $\ell$ from equation (\ref{hyperbol}) and work with the corresponding dimensionless ones as follows:
\begin{equation}
    T := \frac{t}{\ell}\ ,\quad {\bf X} := \frac{{\bf x}}{\ell}\ ,\quad {\bf E} := \ell^2 {\bf E}_{\ell}, \quad\textrm{and}\quad {\bf B} := \ell^2 {\bf B}_{\ell}\ .
\end{equation}
Moreover, the fields are solutions of the homogeneous (source-free) Maxwell equations, so they can be freely rescaled by any dimensionless constant factor $\lambda$. Combining the above considerations, one can rewrite (\ref{eq:force1}) (or analogously (\ref{eq:force2})) fully in terms of dimensionless quantities as
\begin{equation}
		\frac{\text{d} (\gamma{\bf V})}{\text{d} T} = \kappa({\bf E} + {\bf V} \times {\bf B})\ ,
\end{equation}
where $\kappa = \sfrac{q\ell^3\lambda}{m}$ is a dimensionless parameter. As for the initial conditions, we mostly work in the following two scenarios:
\begin{enumerate}[label=(\alph*)]
\item ${\bf V}_0 \equiv {\bf V}(T{=}0) = 0$ with particles symmetrically (with respect to the origin) positioned along a line, a circle, or a sphere around the origin at $T{=}0$, and
\item ${\bf X}_0 \equiv {\bf X}(T{=}0) = 0$ with particle velocities directed radially outward in a symmetric (with respect to the origin) fashion along a line, in a plane or in space at $T{=}0$.
\end{enumerate}

We vary several parameters including the initial conditions (a) and (b) with different directions of lines and planes for each configuration, the value of $\kappa$, and the simulation time in order to study the behavior of the trajectory. In general, we used the value of $R_{max}(0)$ for each field configuration to have particles with initial conditions positioned near the region of maximum energy of the field. In this scenario, the effect of the field on the trajectories of the particles is more prominent, as expected. For particles positioned along a sphere centered around the origin we use (i) the radius of the sphere to be $R_{max}$, and (ii) the radius of the sphere to be very small. The latter scenario helps us understand small perturbations of the trajectories as compared to a particle starting at rest from the origin. Moreover, for the initial condition of kind (b) we use the particle initial speeds in the range where it is (i) non-relativistic, (ii) relativistic (usually between $0.1$ and $0.9$), and (iii) ultrarelativistic (here, $0.99$ or higher).

We observe a variety of different behaviors for these trajectories, some of which we summarize below with the aid of figures. Firstly, it is worth noticing that, even with all fields decreasing as powers of both space and time coordinates, in most field configurations we observe particles getting accelerated from rest up to ultrarelativistic speeds. The limit of these ultrarelativistic speed for higher times depend on the magnitude of the fields (see, for example, Figure \ref{singleTrajectory}).
\begin{figure}[H]
\centering
   \includegraphics[width = 5cm, height = 5cm]{Trajectory_h,-h,-3h.pdf}

 Left: Particle trajectory, Center: absolute velocity profile for $
\kappa {=} 10$, Right: absolute velocity profile for $\kappa {=} 100$.}
\label{singleTrajectory}
\end{figure}

With fixed initial conditions (of kind (a) or (b)) and for higher values of $\kappa$ one can expect, in general, that the initial conditions may become increasingly less relevant. To this end, we find that the particles get focused and accumulate like a beam of charged particles (the beam is quite narrow for some configurations and higher $\kappa$) along some specific region of space and move asymptotically for higher simulation times. This is exemplified below with two $j{=}0$ configurations: the $(0,0,1)_I$ configuration in Figure \ref{j001plots}, and the Hopf--Rañada configuration in Figure \ref{HRplots}. We have verified this feature not just with symmetric initial conditions of particles like that with initial conditions (a) and (b) (as in Figure \ref{j001plots}), but also in several initial conditions asymmetric with respect to the origin, like particles located randomly inside a sphere of fixed radius about the origin with zero initial velocity, and particles located at the origin but with different magnitudes of velocities. Figure \ref{HRplots} is an illustrative example for both of these latter scenarios of asymmetric initial conditions.

\label{HRplots}
\end{figure}

This is not always the case though. For some $j{=}\tfrac12$ and $j{=}1$ configurations, and with initial particle positions in a sphere of very small radius about the origin, we are able to observe the splitting of particle trajectories (starting in some specific solid angle regions around the origin) into two, three or even four such asymptotic beams that converge along some particular regions of space (depending on the initial location of these particles in one of these solid angle regions). Trajectories generated by two such $j{=}1$ configurations have been illustrated in Figure \ref{3-4furcation}.

\label{3-4furcation}
\end{figure}

Naturally, there are also regions of unstable trajectories for particles starting between these solid angle regions (see Figure \ref{Bifurcation}), which generally include the preferred $z$-axis, since in some cases trajectories that start at rest in the $z$-axis never leave it.
\begin{figure}[H]

\label{Bifurcation}
\end{figure}

For particles with initial condition (a), we find that their trajectories are symmetric as far as time reversal around $T{=}0$ is concerned. We illustrate this feature with Figure \ref{1Dpos} where particles with initial position along a line has been considered for better visualization. Of course, choosing a different initial condition would violate this bevaviour as is clear from Figure \ref{singleTrajectory}.

We employ the paramter $R_{max}$ \eqref{Rmax} in the the following Figures \ref{1Dpos}, \ref{1Dvel}, \ref{2Dvel}, \ref{3Dvel}, \ref{2Dpos}, and \ref{3Dpos} for both kinds of initial conditions viz. (a) and (b) (it is especially relevant for the former) to understand the effect of field intensity on particle trajectories.
\begin{figure}[H]

 Left: particles located along $z$-axis (blue line), Right: particles located along some (blue) line in $xy$-plane.}
\label{1Dpos}
\end{figure}

One very interesting feature of trajectories for some of these field configurations is that they twist and turn in a coherent fashion owing to the symmetry of the background field. For particles with initial condition of kind (b), we see that their trajectories take sharp turns, up to two times, with mild twists before going off asymptotically. This has to do with the presence of strong background electromagnetic fields with knotted field lines. This is clearly demonstrated below in Figures \ref{1Dvel}, \ref{2Dvel}, and \ref{3Dvel}. It is worthwhile to notice in Figure \ref{1Dvel} that the particle which was initially at rest moves unperturbed along the $z$-axis; again, this has to do with the fact that these fields have preferred $z$-direction.
\begin{figure}[H]

   \includegraphics[width = 7cm, height = 5cm]{VelLine_1,0,0_1tf.pdf}\hspace{1cm}

 Left: particles simulated for $t \in [0,1]$, Right: particles simulated for $t \in [0,3]$.}
\label{1Dvel}
\end{figure}

This feature is even more pronounced in Figure \ref{2Dvel} and (the right subfigure of) Figure \ref{3Dvel} where we see that particles with ultrarelativistic initial speeds are forced to turn (almost vertically upwards) due to the strong electromagnetic field. These particles later take very interesting twists in a coherent manner. This twisting feature is much more refined for the case where initial particle velocities were directed along the $xy$-plane. Here also, we can safely attribute this behavior of the particle trajectories to the special field configurations, with preferred $z$-direction, that we are working with.

 Left: $|{\bf V}_0|=R_{max}$ and $\kappa {=} 10$, Right: $|{\bf V}_0|=0.99$ and $\kappa {=} 100$.}
\label{3Dvel}
\end{figure}

 We see in Figure \ref{2Dpos} that the trajectories of particles that were initially located on a circle whose normal is along the $z$-axis flow quite smoothly along the $z$-axis with mild twists for some time before they all turn symmetrically in a coherent way and went off asymptotically. Comparing this with the other case in Figure \ref{2Dpos}, where particles split into two asymptotic beams, we realize that this is yet another instance of the preferred choice of direction for the electromagnetic fields influencing the trajectories of particles.

\begin{figure}[H]
\centering
   \includegraphics[width = 7cm, height = 5cm]{PosCirc_1,0,0_Xnormal.pdf}\hspace{1cm}

 Left: the normal of the circle is along the $x$-axis, Right: the normal of the circle is along the $z$-axis.}
\label{2Dpos}
\end{figure}

In Figures \ref{3Dpos} and \ref{2Dvel} we find examples of kind (a) and (b) respectively where both twisting as well as turning of trajectories is prominant. We see in Figure \ref{3Dpos} that the particles that start very close to the origin takes a longer time to show twists as compared to the ones that start off on a sphere of radius $R_{max}$. This is due to the fact that the field is maximal at $R_{max}$ and hence its effect on particles is prominent, as discussed before. We also notice here that the particles sitting along the $z$-axis at $T{=}0$ (either on the north pole or on the south pole of this sphere) keep moving along the $z$-axis without any twists or turns. This exemplifies the fact that these background fields have a preferred direction.
\begin{figure}[H]

   \includegraphics[width = 3cm, height = 7cm]{PosSphere_1,-1,1_10k.pdf}\hspace{2cm}

\label{3Dpos}
\end{figure}

For field configurations with $j {=} \tfrac32$ and $2$ we found in some simulations (with the same parameters i.e. $\kappa$, initial conditions, and simulation time) that their effect on particle trajectories is much less prominent as compared to the $j\leq 1$ field configurations. This indicates that the field intensity may decrease quickly for higher $j$ configurations. This prompts the speculation that, depending on the desired degree of precision, for practical purposes it may be enough to expand any finite energy field configuration in terms of up to $j{=}1$ modes of these basis configurations.

\section{Conclusions}

We have discussed the trajectories of charged particles subject to knotted electromagnetic fields generated by the ``de Sitter method". We first reviewed the construction of the fields using the aforementioned method, followed by a discussion of some of their features, including field lines and energy densities in different cases. Afterwards, we discussed trajectories of charged particles in those fields, in different settings.

Various behaviors were obtained by a numerical simulation of the trajectories, including a separation of trajectories into different ``solid angle regions" that converge asymptotically into a beam of charged particles along a few particular regions of space, an ultrarelativistic acceleration of particles and coherent twists/turns of the trajectories before they go off asymptotically.

The results contribute to an effort to better understand the interactions between electromagnetic knots and charged particles. This becomes increasingly relevant as laboratory generation of knotted fields progresses. Further work in this direction could be to analyze a single Fourier mode of these solutions to understand its experimental realization via monochromatic laser beams.

Borough Market é um mercado de alimentos por atacado e varejo em Southwark, Londres, Reino Unido. É um dos maiores e mais antigos mercados de alimentos da cidade.

História
O mercado atual, localizado na Southwark Street e Borough High Street, ao sul da Catedral de Southwark, no extremo sul da Ponte de Londres, é um sucessor de um que originalmente ficava adjacente ao final da ponte. Foi mencionado pela primeira vez em 1276, embora o próprio mercado declare que exista desde 1014 "e provavelmente muito mais cedo" e posteriormente foi movido para o sul da Igreja de Santa Margarida.

Três terrorista dos ataques de Londres de junho de 2017 correram para o local, onde atacaram várias pessoas com lâminas antes de serem mortos a tiros por policiais armados. Isso aconteceu depois que eles fugiram de um veículo na Ponte de Londres.

The galaxy
In 1956, Sidney Nolan travelled to the Dardanelles in Turkey, a place synonymous with the Trojan War and Anzac folklore. Nolan was inspired by his reading of Homer's verse The Illiad and Alan Moorehead's 1955 article 'Return to a legend', which likened the siege of Troy to the Gallipoli landings. These experiences and influences culminated in Nolan's epic 'Gallipoli' series. 'The galaxy' 1957–58 depicts a ghostly march of figures emerging from a vortex of swirling and speckled green paint; an allegorical time warp in which the memories of war and the soldiers who lost their lives reverberate from the past into the present. The imagery expresses the fear of nuclear threat after World War II, recalling the particles of an atom bomb as well as the deep recesses and existential nothingness of space.

Flying on a budget has never been easier than it is today. More affordable with more options, the choice to find a cheap seat is as easy as it is economical. Budget airlines are a significant part of air travel and many larger, more established airlines are altering their practices to adopt many "non-inclusive" fees enabling passengers to pay for the absolute minimum.
You can fly from Sydney to Los Angeles for just over a grand, Brisbane to Tokyo for under $500 and from Perth to Bali for less than the cost of a cab ride in Melbourne. We cram into smaller seats, forgo in-flight entertainment and fly through China to save a few hundred bucks.
Friends of mine flew to North America and Europe via China recently to save $500 over a direct flight. The layovers added almost an entire day to their trip and cost them substantial headaches. They dealt with having to re-check in before re-boarding the connecting flight, were confused by Chinese airports, and dealt with unhelpful staff on the ground. All of these are ingredients to a painful holiday; something that defeats the purpose of a holiday to begin with. I understand that there are circumstances that crop up during your travels that can lead to frustration, but these are self-inflicted issues that can be avoided if you take into consideration that your holiday doesn't start when you land at your destination.
Your holiday starts when you leave your house. Everything that happens after is part of your holiday. So plan and spend accordingly.
The biggest costs of your holidays are often your flights (or at least, they should be). If you're flying across oceans to continents afar, a good majority of your time will be spent in the air, so why start out with stopovers and subpar airlines?
If you've got the money to travel business class or first class, then most of this is superfluous information. You're probably going to be comfortable no matter where you go. However, for most of us traveling economy, there are a few ways to avoid early onset holiday stress that I believe are part of every good travel plan.
It may cost you a few hundred dollars more to fly from Melbourne straight to L.A., but I can guarantee you that you will wish you did when you're waiting in frustration at one of China's many substandard aviation hubs. It's not worth it.
If you have to stopover, find well known airports and cities that provide you comfort, ease and a mostly stress free environment.
For those traveling through Asia, the two best hubs are Changi Airport in Singapore and Hong Kong International. If you've got to stopover in Asia somewhere, make it either one of these and you'll find that your stopover can be luxurious, comfortable and easy to navigate as you wait to pass the time. Both airports have excellent facilities for those either looking for food, recuperation (plenty of free massage chairs) or shopping.
Thinking about flying budget airlines on a trip longer than a few hours? Don't do it. They are budget airlines for a reason and while the price is right, you'll be wondering why you're suddenly paying for check-in luggage. Sure, there are plenty of carriers that tackle long haul flights on the cheap; Australia's Jetstar has many Asian cities on its destinations list while AirAsia does the same. Singapore Airlines recently launched their own budget carrier Scoot that will fly from Melbourne to Singapore for just $229. It's ridiculously inviting, but what are you paying for? They've got a host of economy class options that include a "ScootSilence" seat that in reality means you're just paying for a different colour seat. They're "unabashedly no-frills" and "managed to significantly undercut the market by modifying its planes to have less space between seats, so more passengers can be packed on board." I understand the majority of airlines are packing in more seats to compete in this market, but an airline that's proud of it? No thanks.
I've never felt more nervous about flying in my life than the few times I flew budget for trips that lasted a mere hour.
My solution is to stick to the bigger airlines that have a great track record and who take extra care in doing what they can for their passengers. In an age where airlines of all kinds are cutting costs and optioning even the most basic of comforts, it is important to think above and beyond. The airlines I tend to stick to for international routes are Qantas, Singapore Airlines, Garuda Indonesia and Virgin. All of them offer fantastically competitive rates when you're flying across the globe and the comforts and service they offer in Economy Class far surpass the rest.
Most airlines have the option for premium economy seats (economy seats with a little more room) and in most cases, the ability for you to choose bulkhead seats (the seats directly behind the physical partition that divides a plane into different classes or sections—or the seats with lots of leg room). If this is the case, then spend the extra money on these seats for long haul flights.
On our recent trip to Canada, we spent $180 each to upgrade our Qantas economy seats to bulkhead seats. I can't begin to tell you how much better it is to have that extra leg room while never having to worry about stepping over anyone to go to the toilets. You have room to stretch out anytime and some additional breathing space. It's all part of making that 16-hour haul as enjoyable as possible. Our flight was just part of a 30+ hour day that included 3 flights and a significant drive, so reducing as much stress as we could was a priority.
Growing up, flying was a privilege. Safety, quality, and class are things I hold in high regard when it comes to flying and I'd like to enjoy as much of it as I can. Like renting a car on your holiday, you should find ways to make the most out of it from the get-go.
I don't know where the airline market is heading to and whether or not things will turn around in the near future, but I'd like to see airlines move away from all these "pay for what you want" options and return to more expensive, more inclusive seating plans. When we realize that flying an airline that gives you the option of paying less to sit on a plastic deck chair at the back of the plane is a truly terrible idea, we'll be heading in the right direction. When it comes to living mostly, flying is something you should never go cheap on.

Is Sempra Energy (SRE) A Good Stock To Buy?
Published on June 20, 2019 at 9:24 pm by Reymerlyn Martin in Hedge Funds,News
Hedge funds are known to underperform the bull markets but that's not because they are terrible at stock picking. Hedge funds underperform because their net exposure in only 40-70% and they charge exorbitant fees. No one knows what the future holds and how market participants will react to the bountiful news that floods in each day. However, hedge funds' consensus picks on average deliver market beating returns. For example in the first 5 months of this year through May 30th the Standard and Poor's 500 Index returned approximately 12.1% (including dividend payments). Conversely, hedge funds' top 20 large-cap stock picks generated a return of 18.7% during the same 5-month period, with the majority of these stock picks outperforming the broader market benchmark. Interestingly, an average long/short hedge fund returned only a fraction of this value due to the hedges they implemented and the large fees they charged. If you pay attention to the actual hedge fund returns versus the returns of their long stock picks, you might believe that it is a waste of time to analyze hedge funds' purchases. We know better. That's why we scrutinize hedge fund sentiment before we invest in a stock like Sempra Energy (NYSE:SRE).
Sempra Energy (NYSE:SRE) shareholders have witnessed a decrease in hedge fund interest in recent months. Our calculations also showed that SRE isn't among the 30 most popular stocks among hedge funds.
So, why do we pay attention to hedge fund sentiment before making any investment decisions? Our research has shown that hedge funds' small-cap stock picks managed to beat the market by double digits annually between 1999 and 2016, but the margin of outperformance has been declining in recent years. Nevertheless, we were still able to identify in advance a select group of hedge fund holdings that outperformed the market by 40 percentage points since May 2014 through May 30, 2019 (see the details here). We were also able to identify in advance a select group of hedge fund holdings that underperformed the market by 10 percentage points annually between 2006 and 2017. Interestingly the margin of underperformance of these stocks has been increasing in recent years. Investors who are long the market and short these stocks would have returned more than 27% annually between 2015 and 2017. We have been tracking and sharing the list of these stocks since February 2017 in our quarterly newsletter. Even if you aren't comfortable with shorting stocks, you should at least avoid initiating long positions in our short portfolio.
Let's take a look at the latest hedge fund action surrounding Sempra Energy (NYSE:SRE).
What does the smart money think about Sempra Energy (NYSE:SRE)?
At the end of the first quarter, a total of 31 of the hedge funds tracked by Insider Monkey were long this stock, a change of -9% from one quarter earlier. The graph below displays the number of hedge funds with bullish position in SRE over the last 15 quarters. With hedge funds' sentiment swirling, there exists an "upper tier" of notable hedge fund managers who were increasing their stakes substantially (or already accumulated large positions).
Among these funds, Elliott Management held the most valuable stake in Sempra Energy (NYSE:SRE), which was worth $1428.5 million at the end of the first quarter. On the second spot was Zimmer Partners which amassed $1030.1 million worth of shares. Moreover, Electron Capital Partners, Citadel Investment Group, and AQR Capital Management were also bullish on Sempra Energy (NYSE:SRE), allocating a large percentage of their portfolios to this stock.
Judging by the fact that Sempra Energy (NYSE:SRE) has witnessed bearish sentiment from the smart money, we can see that there was a specific group of fund managers that slashed their entire stakes last quarter. It's worth mentioning that Jonathan Barrett and Paul Segal's Luminus Management sold off the biggest stake of all the hedgies followed by Insider Monkey, valued at about $18.5 million in stock. Matthew Hulsizer's fund, PEAK6 Capital Management, also said goodbye to its stock, about $3.7 million worth. These bearish behaviors are intriguing to say the least, as total hedge fund interest was cut by 3 funds last quarter.
Let's now review hedge fund activity in other stocks similar to Sempra Energy (NYSE:SRE). We will take a look at Ross Stores, Inc. (NASDAQ:ROST), Ford Motor Company (NYSE:F), V.F. Corporation (NYSE:VFC), and SYSCO Corporation (NYSE:SYY). All of these stocks' market caps are similar to SRE's market cap.
ROST 29 907288 -4
F 33 1106452 0
VFC 29 1091453 2
SYY 36 2944902 2
Average 31.75 1512524 0
As you can see these stocks had an average of 31.75 hedge funds with bullish positions and the average amount invested in these stocks was $1513 million. That figure was $2902 million in SRE's case. SYSCO Corporation (NYSE:SYY) is the most popular stock in this table. On the other hand Ross Stores, Inc. (NASDAQ:ROST) is the least popular one with only 29 bullish hedge fund positions. Sempra Energy (NYSE:SRE) is not the least popular stock in this group but hedge fund interest is still below average. Our calculations showed that top 20 most popular stocks among hedge funds returned 1.9% in Q2 through May 30th and outperformed the S&P 500 ETF (SPY) by more than 3 percentage points. A small number of hedge funds were also right about betting on SRE as the stock returned 4.5% during the same time frame and outperformed the market by an even larger margin.
Here's What Hedge Funds Think About Noble Energy, Inc. (NBL) Here's What Hedge Funds Think About PerkinElmer, Inc. (PKI) Here's What Hedge Funds Think About Metlife Inc (MET) Here's What Hedge Funds Think About Five9 Inc (FIVN) Here's What Hedge Funds Think About Prudential Financial Inc (PRU) Investors Don't Find Short Seller's Claims Credible

Andrzej Frycz Modrzewski (Andreas Fricius Modrevius) armoiries Jastrzębiec, né le  et mort  1572 à Wolbórz est un éminent écrivain politique humaniste et théologien polonais de la Renaissance, secrétaire du roi de Pologne Zygmunt August .

Biographie
Andrzej Frycz Modrzewski naît dans une famille de petite noblesse provinciale de Cujavie. Son père occupe la charge héréditaire de maire de Wolbórz (avec fonctions économiques et judiciaires). Modrzewski y fréquente une école paroissiale jusqu'en 1514. En 1517, il entre à l'Université Jagellonne de Cracovie, alors sous le rectorat de l'historien et géographe Maciej de Miechów qui encourage les courants humanistes.

Modrzewski reçoit les ordres mineurs et, en 1523, il entre à la chancellerie de l'évêque de Gniezno, Jan Łaski, primat de Pologne et chancelier de Pologne, sans doute l'homme le plus influent du pays. Il devient le familier les neveux du primat, dont Jan Laski, dit «le Réformateur». En 1525, Modrzewski est nommé secrétaire de l'évêque de Poznan, Jan Latalski.

En 1531, Modrzewski continue ses études à l'Université de Wittenberg où il se familiarise avec les idées de la Reforme. Elles influencent fortement sa pensée. Il perfectionne sa connaissance du grec auprès de Philipp Melanchthon qui le prend en amitié et chez lequel il habite. Mais les idées théologiques des luthériens n'auront pas de prise sur lui. À la mort d'Érasme de Rotterdam, Modrzewski se rend à Bâle pour prendre possession de sa bibliothèque et la rapporter en Pologne. Jan Laski le Réformateur avait, en effet, acheté à Érasme ses livres en lui en laissant l'usufruit jusqu'à sa mort. Modrzewski voyage ensuite en Europe où il assiste à la formation de la ligue protestante.

De retour en Pologne en 1540, il reçoit la cure de Brzeziny mais s'installe à Cracovie pour écrire. Il fréquente alors le cercle formé d'esprits intéressés par la Réforme. À l'exception de Stanisław Orzechowski, ces amis lui resteront fidèles jusqu'à sa mort malgré les divergences confessionnelles.

Dans son premier traité Łaski, czyli o karze za mężobójstwo (Les pardons ou sur une punition pour homicide, 1543), Andrzej Frycz Modrzewski exige l'égalité de tous les citoyens devant la loi et demande le même châtiment pour meurtre pour les nobles et les plébéiens. Dans son traité suivant, il critique la restriction de droits fonciers des bourgeois et demande leur participation dans les institutions politiques nationales.

Malgré les polémiques provoquées par ces ouvrages, Modrzewski sera, en 1551, nommé secrétaire de l'ambassade polonaise auprès du concile de Trente. A cette occasion, il entre en conflit avec l'évêque romaniste Stanisław Hozjusz car il propose qu'une délégation laïque, en plus du clergé, soit envoyée au concile de Trente.

Il est appelé un apostat par les catholiques romains, mais ceci ne l'empêcha de devenir en 1547 secrétaire secrétaire à la chancellerie royale de Zygmunt II. Il fait alors partie de trois missions diplomatiques majeures auprès de Charles Quint (1547), Albert de Prusse (1548) et Ferdinand (1549).

Œuvre
Son oeuvre le plus célèbre ainsi que l'ouvrage polonais le plus connu hors frontières, au XVIe siècle, qui fait même dédier par Ronsard un sonnet «au grand Osie», est le traité politique De Republica emendanda (Sur la réforme de la République, 1551).

Modrzewski y présente des idées égalitaires, en particulier dans le chapitre consacrés aux droits. Il crée sa propre vision du pouvoir central et critique fortement l'Église catholique. Pour cette raison, son travail est placé en 1559 sur l'index des livres interdits.

En 1553, à la mort de son père, Modrzewski lui succède dans sa charge héréditaire de bailli de Wolbórz. Mais ce poste lui a est retiré en 1569 en raison d'une violation des vœux de sacerdoce (il se marie) et surtout sa critique de l'Eglise.

Il décède trois ans plus tard.

Q: SQL WHERE clause error I want to put where clause below for totalscore > 50
But when I put where totalscore > 50 after order by there is some error.
SELECT
    h.hacker_id, h.name, SUM(ss.maxscore) totalscore
FROM
    (SELECT
         hacker_id, challenge_id, MAX(score) maxscore
     FROM
         submission_table s
     GROUP BY
         challenge_id, hacker_id) AS ss
JOIN
    hacker_table h ON ss.hacker_id = h.hacker_id
GROUP BY
    h.hacker_id
ORDER BY
    totalscore DESC, hacker_id ASC
WHERE
    totalscore > 50

A: The others are correct regarding WHERE but I think from your description you want
HAVING SUM(ss.maxscore)>50

A: If your looking for a true/false on the score being above 50 as part of the sort then you'd use:
ORDER BY score, totalscore>50

Although just adding totalscore to the order make more sense.
If your trying to only get those with a totalscore > 50 then without knowing your tables the easiest thing to do is add another subselect
SELECT * FROM
    ( SELECT h.hacker_id,h.name,SUM(ss.maxscore) totalscore
      from (
        SELECT hacker_id,challenge_id,MAX(score) maxscore
        FROM submission_table s
        GROUP BY challenge_id,hacker_id
      ) as ss
      JOIN hacker_table h
      ON ss.hacker_id = h.hacker_id
      GROUP BY h.hacker_id
    )
    Where totalscore > 50
    Order by totalscore Desc,hacker_id ASC
