Using a Composite Maternal-Infant Outcome Measure in Tuberculosis-Prevention Studies among Pregnant Women
Grace Montepiedra, Soyeon Kim, Adriana Weinberg, Gerhard Theron, Timothy R. Sterling, Sylvia M. Lacourse, Sarah Bradford, Nahida Chakhtoura, Patrick Jean-Philippe, Scott Evans, Amita Gupta
Background: Tuberculosis (TB-)-preventive therapy (TPT) among pregnant women reduces risk of TB in mothers and infants, but timing of initiation should consider potential adverse effects. We propose an analytical approach to evaluate the risk-benefit of interventions. Methods: A novel outcome measure that prioritizes maternal and infant events was developed with a 2-stage Delphi survey, where a panel of stakeholders assigned scores from 0 (best) to 100 (worst) based on perceived desirability. Using data from TB APPRISE, a trial among pregnant women living with human immunodeficiency virus (WLWH) that randomized the timing of initiation of isoniazid, antepartum versus postpartum, was evaluated. Results: The composite outcome scoring/ranking system categorized mother-infant paired outcomes into 8 groups assigned identical median scores by stakeholders. Maternal/infant TB and nonsevere adverse pregnancy outcomes were assigned similar scores. Mean (SD) composite outcome scores were 43.7 (33.0) and 41.2 (33.7) in the antepartum and postpartum TPT initiation arms, respectively. However, a modifying effect of baseline antiretroviral regimen was detected (P = .049). When women received nevirapine, composite scores were higher (worse outcomes) in the antepartum versus postpartum arms (adjusted difference, 14.3; 95% confidence interval [CI], 2.4-26.2; P = .02), whereas when women received efavirenz there was no difference by timing of TPT (adjusted difference,. 62; 95% CI,-3.2-6.2; P = .53). Conclusions: For TPT, when used by otherwise healthy persons, preventing adverse events is paramount from the perspective of stakeholders. Among pregnant WLWH in high-TB-burden regions, it is important to consider the antepartum antiretroviral regimen taken when deciding when to initiate TPT.

Q: Use Lagrange multipliers to find the maximum possible value for $x_1x_2 · · · x_n$ Let $x_1, . . . , x_n$ be nonnegative real numbers, and suppose that
$x_1 + · · · + x_n = c$, where c is a fixed positive constant.
Use Lagrange multipliers to find the maximum possible value for $x_1x_2 · · · x_n$ in terms of c
and n.
I haven't had much exposure to Lagrange multipliers. How would I use the Lagrange function to solve this problem? Thanks!

A: Optimize
$$f(\vec x) = \prod_{k=1}^nx_k $$
Subject to the constraint
$$ G(\vec x) = \sum_{k=1}^nx_k =c   $$
The idea is that the constrained max must occur where $\vec \nabla f  \parallel \vec \nabla g  $ because $\vec \nabla g  $  is the only direction that $\vec \nabla f  $ can have while all directional derivatives vanish on the $n-1$ dimensional surface defined by the constraint.
In this case looking at the $p^{th}$ components ...
$$  \left(  \vec \nabla g \right)_p=1  $$
$$  \left(  \vec \nabla f \right)_p= \frac{\prod_{k=1}^nx_k }{x_p}  $$
clearly all the components of $ \vec \nabla f $ must be equal
so $x_p = \frac cn$
and the optimal value of $f$ constrained to $g$ is $\left( \frac {c}{n} \right)^n$

The Lost Girls is told in a steady, very somber/dark tone. It is multi layered with many surprising twists.
There are two narrators for this novel. One narrative is about three young sisters and their relationship while spending the summer at the family's lake house,. It is told by one narrator in the voice of the middle sister, Lucy.
The second narration is about Lucy's grand-neice, Justine, who inherits the house. Justine has two daughters.
Having two different narrators was very effective. Lucy is writing about that summer for Justine to read and know about what happened. The author, Heather Young's talents are clearly on display.
The Lost Girls gives you pause for thought about families, the relationships that exist behind closed doors and the evil that may be lurking there.
If the author's second novel, Lovelock, is as good as her first, The Lost Girls, it will be a doozy.
This novel is reminiscent of another 5-star rated novel, A Reliable Wife by Robert Goolrick (my review ~ 2014).
After a decade practicing law and another raising kids, Heather decided to finally write the novel she'd always talked about writing. She holds an MFA from the Bennington Writing Seminars, and is an alumnus of the Squaw Valley Writers Workshop and the Tin House Writers Workshop, all of which helped her stop writing like a lawyer. She lives in Mill Valley, California, with her husband and two teenaged children. When she's not writing she's biking, hiking, neglecting potted plants, and reading books by other people that she wishes she'd written.
She is currently working on her second novel, Lovelock.
This does sound like a very impressive debut! I'm glad that you enjoyed this audio book, Pat. Excellent review!
Good to hear this was a very satisfying listen for you Pat and that the narrators worked out really well.
I am putting this on my wish list for the library. Hope it's available as an ebook! Enjoyed your review.

With three days in Sydney, you have plenty of time to soak up the city's atmosphere, see its most famous sights, loll on the beach, and head out of town into the surrounding countryside. Here are a few ways to experience the very best of Sydney in 72 memorable hours.
Day 1: Explore Sydney Harbour Sydney Harbour, with its iconic UNESCO World Heritage–listed opera house and dramatic Sydney Harbour Bridge, makes up the city's most recognizable image. One of the best ways to take in the sights is aboard a catamaran or tall-ship tour around the harbor. Tour boats typically cruise close to the Sydney Opera House and bridge, allowing for excellent photo opportunities. Some tours include lunch or dinner, and others offer additional experiences such as entry to the Taronga Zoo. Alternatively, consider a scenic helicopter tour for a wide-angle view of the harbor and Sydney skyline.
After seeing the harbor highlights from a distance, you can get up close on a guided climb to the top of the Sydney Harbour Bridge, a backstage Sydney Opera House tour, or by attending an opera or ballet inside the world-famous performing arts venue.
Day 2: Spend a Day at the Beach No visit to Sydney is complete without spending some time soaking up the sun on at least one of its legendary beaches. Famed Bondi Beach is just five miles (eight kilometers) from the city center, so both Sydney and Bondi sightseeing tours offer the chance to take a stroll along the beach and dip your feet in the warm water. Alternatively, Sydney and Bondi hop-on hop-off bus and boat tours allow you to set your own itinerary and take your time at the beach before continuing on to other stops along the sightseeing route.
More sand-and-sea options lie just a short distance from the city, including bustling Manly. Some Sydney tours include visits to Manly and the Northern Beaches, and usually allow for free time to enjoy the beach area.
Day 3: Experience the Blue Mountains Sydneysiders looking to escape into nature flock to the serene Blue Mountains, easily and quickly accessible from the city center. Guided full-day Blue Mountains tours (private or group) typically take in the region's most famous sights, such as the distinctive rock formation of the Three Sisters, and many include stops at additional attractions, such as a wildlife park where you can see kangaroos, koalas, and other native critters.
Alternatively, spend a day exploring Australia's oldest wine-producing region. Guided Hunter Valley wine tours with hotel pickup and drop-off take the worry out of driving after indulging in some wine tasting, and often include lunch with wine pairings.
Big Bus Sydney and Bondi Hop-on Hop-off Tour
Join a hop-on hop-off sightseeing tour by double-decker bus to discover the highlights of Sydney and Bondi Beach. Enjoy unobstructed views and recorded onboard commentary as you travel along two routes to top destinations like Sydney Harbour Bridge, Sydney Opera House, Darling Harbour, and Bondi Beach. Go in-depth at any given place by simply hopping off the bus to explore. You can experience Sydney and Bondi's most noteworthy attractions at your own pace with your choice of ticket, valid for either 24 or 48 hours.
Opera Performance at the Sydney Opera House
Be sure to put a performance by Opera Australia at the iconic Sydney Opera House on your Sydney itinerary. See classic operas by composers like Mozart and Puccini, as well as iconic Broadway musicals, depending on the season. Take in stunning views of Sydney Harbour while enjoying drinks or a meal (own expense) at one of the Opera House's fine dining venues before or after the performance to top off this unforgettable experience.
Sydney Harbour Sunset Dinner Cruise
Enjoy a deluxe sunset cruise on Sydney Harbour accompanied by a delicious three-course dinner. From the water, admire iconic sights such as Sydney Harbour Bridge, Sydney Opera House, Fort Denison, Luna Park and more. Snap photos as the sky shimmers at sunset and the city skyline lights up for the night as you cruise through Sydney in the evening.
Sydney Harbour Ferry with Taronga Zoo Entry Ticket
Take in panoramic views of top Sydney landmarks as you cruise through Sydney Harbour en route to Taronga Zoo. Your package includes round-trip cruise from Circular Quay to the zoo, and a ride on the Sky Safari Gondola, which whisks you uphill from the boat dock to the main entrance of Taronga Zoo. From the gondola, get an early peek at some of the zoo's inhabitants, such as giraffes, big apes, and native animals like kangaroos and koalas.
Sydney Harbour Tour by Helicopter
Enjoy sweeping views of Sydney Harbour and beyond during a scenic helicopter flight over Sydney. Take to the skies for a quick flight that provides stunning panoramic views of Sydney's eastern coastline including Coogee Beach, Bondi Beach, Manly Cove, Sydney's spectacular Harbor and city skyline, the Sydney Harbour Bridge, and Sydney Opera House. Learn about the city's history from your knowledgeable pilot as you fly along the coast of the Pacific Ocean before your pilot whirs over Sydney Head marking the harbor's entrance.
Small-Group Blue Mountains Day Trip from Sydney with Wildlife Park
Enjoy a visit to the Blue Mountains while in Sydney. Your full-day tour of the World Heritage-listed park visits highlights including the Three Sisters, Wentworth Falls, and Jamison Valley. En route, stop at Featherdale Wildlife Park, and have your photo taken with cuddly koalas. Travel with a small group, providing a more intimate experience.

Gameloft Delays Disney Speedstorm to 2023
Priyansh Sidhwani· December 5, 2022
In an announcement, Gameloft revealed their plans of delaying Disney Speedstorm until 2023. Essentially, that suggests a new release window is likely in store in the later part of 2023. We will need to wait a bit longer for Gameloft to provide us with an official release window. Based on the language in the press release, it seems like both PC and console versions of the game are going to launch at the same time, but as of writing, that is not confirmed.
In addition to rewarding players with cleaner launches, it also means fans of the IPs in question will enjoy an extra dose of freedom. If you would like to get a little more Disney into your life than you already do, you may want to check out what Gameloft has been doing with Disney Dreamlight Valley. Anyone looking for a new Kart Racer, or who simply wants a good Disney-licensed time, has got that: Disney Speedstorm is polished, even in closed beta, and it is expected to be excellent as a free-to-play title when it launches full-fledged later this year.
According to the post, it appears the game is simply not currently at the level that developers are expecting, and they will continue working on the title in order to deliver more exciting racing experiences, customization offerings, gameplay modes, and more. Gameloft noted it wanted to give players a compelling racing experience, customization options, and various gameplay modes, among others.
While delays are disappointing, the IP in question has hype beyond your racing game, and it is definitely due for fans to get the full game. Originally planned for release sometime this year, hero-based races were delayed until next year in order to provide a better competitive racing experience when it does come out.
Not having a seasonally-at-least release window is kind of a disappointment considering how much time people have been waiting for Disney Speedstorm, but since the game is free-to-play, there is the possibility that they could surprise players with a launch date for the game and claim that it is out in just a few weeks. The delays mean Disney Speedstorm, the racing game similar to Mario Kart, which would have delighted fans of Disney characters, Disney Speedstorm is coming just during the course of 2023, with the most concrete date yet unannounced by Gameloft. Disney Speedstorm will be released for Nintendo Switch, PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, and PC through Epic Games Store and Steam.

\section{Introduction}

Since the discovery of new BiS$_2$-based layered superconductors
LaO$_{1-x}$F$_x$BiS$_2$
by Mizuguchi {\it et al}.\cite{Mizuguchi1,Mizuguchi2,Mizuguchi3},
both experimental and theoretical investigations for the normal and
superconducting properties on BiS$_2$-based materials
have been performed intensively.
This material group has the characteristic layered structure,
similar to high-$T_{\rm c}$ cuprate superconductors,
where $T_{\rm c}$ denotes the superconducting transition temperature.
Namely, BiS$_2$ superconducting layer is sandwiched
by insulating block layers.

Among several BiS$_2$-based compounds,
first we pick up the mother compound LaOBiS$_2$.
This material is insulating, but by substituting F for O,
we can dope electrons into the BiS$_2$ layer.
Then, the system becomes metallic and at low temperatures,
superconductivity occurs eventually.
In particular, at $x=0.5$, the superconducting transition temperature
$T_{\rm c}$ becomes maximum \cite{Mizuguchi3}.
The highest $T_{\rm c}$ among BiS$_2$ material groups
has been obtained in the sample synthesized
under high pressures \cite{Mizuguchi4}.
It has been reported that the onset $T_{\rm c}$ is 11.1 K
and the temperature at which the resistivity becomes zero is 8.5 K.

Although the mechanism of superconductivity in BiS$_2$-based materials
has not been confirmed yet,
the canonical model for this system has been proposed
by Usui {\it et al}.\cite{Usui,Kuroki},
just after the discovery of BiS$_2$-based superconductors.
The minimal model to describe electronic structure of BiS$_2$ layer is
the two-band Hamiltonian composed of
Bi 6$p_x$ and 6$p_y$ orbitals on the two-dimensional square lattice.
The appearance of superconductivity has been discussed from various
theoretical viewpoints on the basis of this two-orbital Hubbard model
\cite{Martins,Zhou,Yang,Liang,Wu}.
The effects of electron-phonon interaction \cite{Yildirim,Wan,Li}
and spin-orbit coupling \cite{Gao} have been also discussed.
The relation between the characteristic change of the
Fermi-surface topology and the symmetry of the superconducting gap function
have been pointed out in previous works \cite{Usui,Kuroki,Martins,Zhou,Yang,Liang}.

Concerning the gap symmetry,
some theoretical studies suggested that the gap function in
BiS$_2$-based layered superconductors could be
explained by extended $s$-wave, $d$-wave, triplet or
other unconventional paring scenarios \cite{Usui,Martins,Zhou,Yang,Liang,Wu}.
On the other hand, $s$-wave pairing due to electron-phonon interaction
has been also discussed \cite{Yildirim,Wan,Li}.
From experimental viewpoints,
the results consistent with $s$- or extended $s$-wave pairing
have been found in the temperature dependence of the superfluid density
in Bi$_4$O$_4$S$_3$ \cite{Srivastava},
LaO$_{0.5}$F$_{0.5}$BiS$_2$ \cite{Lamura},
and NdO$_{1-x}$F$_{x}$BiS$_2$ \cite{Jiao}.
In particular, for NdO$_{1-x}$F$_{x}$BiS$_2$, it has been reported that
the gap symmetry is consistent with
$s$- or extended $s$-wave both for $x=0.3$ and $0.5$ \cite{Jiao}.
It is interesting to consider a way to reconcile those results on the symmetry of the gap
function from a viewpoint
of Fermi-surface topology characteristic to multi-band systems.

In this paper, we analyze the two-dimensional two-band model
including intra- and inter-orbital Coulomb interactions
within a random phase approximation (RPA) to derive the effective pairing
interaction to induce the Cooper pair.
Then, we solve the gap equation to obtain $T_{\rm c}$ and analyze
the gap symmetry by focusing on the Fermi-surface topology.
For $x=0.3$ and $0.4$, we obtain the $d$-wave gap, but the disconnected
Fermi-surface curves with the centers at X and Y points do $not$ cross
the line nodes of the $d$-wave gap.
When we increase $x$, we observe the elevation of $T_{\rm c}$
except for a narrow region around at $x=0.45$ and
the conversion of the gap symmetry from $d$-wave to extended $s$-wave.
In fact, $T_{\rm c}$ takes the maximum value at $x=0.6$.
For $x=0.5$ and $0.6$, we obtain the extended $s$-wave gap
for a couple of large Fermi-surface curves
with the centers at $\Gamma$ and M points.
It is proposed that the conversion of the gap symmetry is
characteristically induced by the variation of the Fermi-surface
topology in the BiS$_2$-layered materials.
Throughout this paper, we use such units as $\hbar=k_{\rm B}=1$.

\section{Model and Formulation}

\subsection{Model Hamiltonian}

The model Hamiltonian is given by~\cite{Usui,Kuroki}
\begin{eqnarray}
  H &=& \sum_{\bm{k}\sigma\tau\tau'}
    \varepsilon_{\bm{k}\tau\tau'}
    c_{\bm{k}\tau\sigma}^{\dag}c_{\bm{k}\tau'\sigma}
    +U \sum_{\bm{i} \tau}
    n_{\bm{i} \tau \uparrow} n_{\bm{i} \tau \downarrow}
    \nonumber\\
    &+&U^{\prime} \sum_{\bm{i}}
    n_{\bm{i}1} n_{\bm{i}2}
    + J \sum_{\bm{i},\sigma,\sigma^{\prime}}
    c^{\dagger}_{\bm{i} 1 \sigma}
    c^{\dagger}_{\bm{i} 2 \sigma^{\prime}}
    c_{\bm{i} 1 \sigma^{\prime}}
    c_{\bm{i} 2 \sigma} \\
    &+& J^{\prime}\sum_{\bm{1},\tau \ne \tau^{\prime}}
    c^{\dagger}_{\bm{i} \tau \uparrow}
    c^{\dagger}_{\bm{i} \tau \downarrow}
    c_{\bm{i} \tau^{\prime} \downarrow}
    c_{\bm{i} \tau^{\prime} \uparrow},\nonumber
\end{eqnarray}
where $c_{\bm{k}\mu\sigma}$ is the annihilation operator of electron with
wave-vector $\bm{k}$ and spin $\sigma$ in the orbital $\tau$ (=1 and 2),
$\varepsilon_{\bm{k}\tau\tau'}$ is the electron energy
between $\tau$ and $\tau'$ orbitals,
$n_{\bm{i} \tau \sigma}=c^{\dagger}_{\bm{i} \tau \sigma} c_{\bm{i} \tau \sigma}$,
$n_{\bm{i} \tau}=\sum_{\sigma} n_{\bm{i} \tau \sigma}$,
and the coupling constants $U$, $U^{\prime}$, $J$, and $J^{\prime}$
denote the intra-orbital Coulomb, inter-orbital Coulomb, exchange,
and pair-hopping interactions, respectively.
Note the relations of $U=U'+J+J'$ and $J=J'$.

\subsection{Electron dispersion}

As for the electron dispersion relation, by following the results
in the paper of Usui {\it et al}.\cite{Usui}, we obtain
\begin{eqnarray}
\varepsilon_{\bm{k}11} &=&
t_0+2t_1 (\cos k_x+\cos k_y) \nonumber \\
&+& 2t_3 \cos (k_x-k_y) +2t_4 \cos (k_x+k_y)  \nonumber \\
&+& 2t_6 [\cos (2k_x+k_y) + \cos (k_x+2k_y)] \nonumber\\
&+& 2t_8  [\cos (2k_x-k_y) + \cos (k_x-2 k_y)],
\end{eqnarray}
\begin{eqnarray}
\varepsilon_{\bm{k}22} &=&
t_0+2t_1 (\cos k_x+\cos k_y) \nonumber \\
&+& 2t_3 \cos (k_x+k_y) +2t_4 \cos (k_x-k_y)  \nonumber \\
&+& 2t_6 [\cos (2k_x-k_y) + \cos (k_x-2k_y)] \nonumber\\
&+& 2t_8  [\cos (2k_x+k_y) + \cos (k_x+2 k_y)],
\end{eqnarray}
and
\begin{eqnarray}
\varepsilon_{\bm{k}12} &=&
\varepsilon_{\bm{k}21} \nonumber \\
&=&2t_2 (\cos k_x-\cos k_y)+2t_5(\cos 2k_x -\cos 2k_y) \nonumber \\
&+&4t_7 (\cos 2k_x \cos k_y - \cos k_x \cos 2k_y).
\end{eqnarray}
The values of $t_0$$\sim$$t_8$ are given by
$t_0$=$2.811$, $t_1$=$-0.167$, $t_2$=$0.107$,
$t_3$=$0.880$, $t_4$=$0.094$, $t_5$=$-0.028$,
$t_6$=$0.014$, $t_7$=$0.020$, and $t_8$=$0.069$
in the unit of eV \cite{Usui}.

The band dispersion is given by
\begin{equation}
  E_{{\bm k}\pm} = \frac{1}{2}
   \left[ \varepsilon_{{\bm k}11}+
\varepsilon_{{\bm k}22}
\pm \sqrt{ (\varepsilon_{{\bm k}11}-
\varepsilon_{{\bm k}22})^2+
\varepsilon_{{\bm k}12}^2} \right].
\end{equation}
Hereafter we define $E_{{\bm k}+}=E_{{\bm k}A}$
and $E_{{\bm k}-}=E_{{\bm k}B}$,
which are called the A and B bands, respectively.

The band structure has been discussed in Ref.~\cite{Usui},
but in order to make this paper self-contained,
we show $E_{{\bm k}A}$ and $E_{{\bm k}B}$ along the path
with high symmetry on the Brillouin zone in Fig.~1(a).
For $x=0.3$ and $0.4$, as shown in the insets,
we observe that the Fermi levels cross only the B band
near the X point, while between M and $\Gamma$ points, they do not
cross the band B.
For $x=0.5$, the Fermi level turns to cross the band B between M and $\Gamma$ points,
but it is still under the band A at the X point.
For $x=0.6$, the Fermi level crosses not only the B band but also the A
band near the X point.

\begin{figure}[t]
\centering
\includegraphics[width=0.98\linewidth]{fig1.eps}
\caption{
(a) $E_{{\bm k}A}$ and $E_{{\bm k}B}$ along the path of
$\Gamma$$\rightarrow$X$\rightarrow$M$\rightarrow$$\Gamma$.
The horizontal broken lines denote the positions of Fermi levels
for $x=0.3$, $0.4$, $0.5$ and $0.6$
from the bottom to the top.

around at $(\pi,0)$ and a point between $(\pi,\pi)$ and $(0,0)$.

and (e) $x=0.6$.
}
\end{figure}

The above characters appear in the change of the Fermi-surface structure,
as shown in Figs.~1(b)-1(e).
In Fig.~1(b), we depict the Fermi-surface curves for $x=0.3$.
A characteristic issue is that pocket-like disconnected Fermi-surface curves
appear around at the X and Y points.
We remark that these Fermi-surface curves originate from the B band and
they do not cross the lines of $k_x=\pm k_y$.
This issue will be important in the discussion of the gap function later.
Another characteristic point is the shape of the Fermi-surface curves.
We observe the disconnected Fermi-surface curves, which possess
the projections extending to the direction to those of
other Fermi-surface curves.
For $x=0.4$, we still observe pocket-like
disconnected Fermi-surface curves around at the X and Y points,
as shown in Fig.~1(c).
Note that the projections further extend to
the directions to other Fermi-surface curves, but they do not touch.

When we further increase $x$, the projections eventually
touch other Fermi-surface curves and the disconnected structure
is dissolved, as observed in Fig.~1(d) for $x=0.5$.
Then, we observe a couple of large Fermi-surface curves
with the centers at the $\Gamma$ and M points.
These two Fermi-surface curves originating from the B band
are formed by the merge of the projections of
pocket-like Fermi-surface curves in Fig.~1(c).
We should pay attention to the existence of the Fermi-surface curves
on the lines of $k_x=\pm k_y$.
We also remark that the topological change of the Fermi-surface
structure occurs around at $x=0.45$,
as already mentioned in Refs.~\cite{Martins} and \cite{Liang}.

Now we further increase the values of $x$.
The Fermi-surface curves for $x=0.6$ are shown in Fig.~1(e).
Here we observe the large Fermi-surface curves around
at the $\Gamma$ and M points, although the shape is slightly deformed
from those for $x=0.5$ in Fig.~1(d).
Note also that new pocket-like Fermi-surface curves appear around
at the X and Y points.
These curves originate from the A band,
in sharp contrast to other Fermi-surface curves.
We find that there occurs the topological change for the appearance of
the Fermi-surface curve
originating from the A band at $x=0.52$,
as already pointed out in Ref.~\cite{Liang}.

\subsection{Spin and orbital susceptibilities}

In order to investigate superconductivity around the spin and/or orbital ordered phases
\cite{Takimoto1,Takimoto2,Takimoto3,Mochizuki1,Mochizuki2,Mochizuki3,Yada,Kubo1,Kubo2},
we calculate spin and orbital susceptibilities,
$\hat{\chi}^{\rm s}({\bm q})$ and $\hat{\chi}^{\rm o}({\bm q})$,
respectively.
Here we follow the formulation and the notations in Ref.~\cite{Takimoto2}.
Within the RPA, spin and orbital susceptibilities are given
in the 4$\times$4 matrix form as
\begin{equation}
  \label{RPAchis}
  \hat{\chi}^{\rm s}({\bm q}) =
  [\hat{1}-\hat{U}^{\rm s}\hat{\chi}({\bm q})]^{-1}
  \hat{\chi}({\bm q}),
\end{equation}
and
\begin{equation}
  \label{RPAchio}
  \hat{\chi}^{\rm o}({\bm q}) =
  [\hat{1}+\hat{U}^{\rm o}\hat{\chi}({\bm q})]^{-1}
  \hat{\chi}({\bm q}),
\end{equation}
respectively.
Here labels of row and column in the matrix appear in the order
of 11, 22, 12, and 21, which are pairs of orbital indices 1 and 2.
Note that $\hat{1}$ is the 4$\times$4 unit matrix.
The interaction matrices $\hat{U}^{\rm s}$ and $\hat{U}^{\rm o}$ are
given by
\begin{equation}
\hat{U}^{\rm s}=\left(
\begin{array}{cccc}
U & J & 0 & 0 \\
J & U & 0 & 0 \\
0 & 0 & U' & J' \\
0 & 0 & J' & U'
\end{array}
\right),
\end{equation}
and
\begin{equation}
\hat{U}^{\rm o}=\left(
\begin{array}{cccc}
U & 2U'-J & 0 & 0 \\
2U'-J & U & 0 & 0 \\
0 & 0 & 2J-U' & J' \\
0 & 0 & J' & 2J-U'
\end{array}
\right),
\end{equation}
respectively.
Each matrix element of $\hat{\chi}({\bm q})$ is defined by
\begin{equation}
\chi_{\mu\nu,\alpha\beta}({\bm q})=
-T\sum_{{\bm k},n}
G^{(0)}_{\alpha\mu}({\bm k}+{\bm q},i\omega_{n})
G^{(0)}_{\nu\beta}({\bm k},i\omega_{n}),
\end{equation}
where $T$ is a temperature,
$G^{(0)}_{\mu\nu}({\bm k},i\omega_{n})$
is the non-interacting Green's function propagating
between $\mu$- and $\nu$-orbitals,
and $\omega_n=\pi T(2n+1)$ with an integer $n$.
The instabilities for the spin- and orbital-ordered phases
are determined by the conditions of
${\rm det}[\hat{1}-\hat{U}^{\rm s}\hat{\chi}({\bm q})]$=0
and ${\rm det}[\hat{1}+\hat{U}^{\rm o}\hat{\chi}({\bm q})]$=0,
respectively.

\subsection{Gap equation}

By using $\hat{\chi}^{\rm s}({\bm q})$ and
$\hat{\chi}^{\rm o}({\bm q})$,
we obtain the superconducting gap equation
in a weak-coupling limit as
\begin{equation}
  \label{gap}
  {\bm \Delta}^{\xi}({\bm k})=\sum_{{\bm k'}}
    \hat{V}^{\xi}({\bm k}-{\bm k'})
    \hat{\phi}({\bm k'}){\bm \Delta}^{\xi}({\bm k'}),
\end{equation}
where ${\bm \Delta}^{\xi}({\bm k})$
=[$\Delta^{\xi}_{11}({\bm k})$, $\Delta^{\xi}_{22}({\bm k})$,
$\Delta^{\xi}_{12}({\bm k})$, $\Delta^{\xi}_{21}({\bm k}$)]$^t$
is the gap function in the vector representation
for singlet ($\xi={\rm S}$) or triplet
($\xi={\rm T}$) pairing state.
The matrix elements of the singlet- and triplet-pairing
potentials are, respectively, given by
\begin{equation}
  V^{\rm S}_{\alpha\beta,\mu\nu}({\bm q})=
   -\frac{3}{2}
    W^{\rm s}_{\alpha\mu,\nu\beta}({\bm q})+
    \frac{1}{2}W^{\rm o}_{\alpha\mu,\nu\beta}({\bm q})
  +U^{\rm s}_{\alpha\mu,\nu\beta},
\end{equation}
\begin{equation}
  V^{\rm T}_{\alpha\beta,\mu\nu}({\bm q})=
   \frac{1}{2}W^{\rm s}_{\alpha\mu,\nu\beta}({\bm q})+
   \frac{1}{2}W^{\rm o}_{\alpha\mu,\nu\beta}({\bm q})
   -U^{\rm s}_{\alpha\mu,\nu\beta},
\end{equation}
which are composed of spin and orbital susceptibilities as
\begin{equation}
  \hat{W}^{\rm s}({\bm q})=\hat{U}^{\rm s}
  +\hat{U}^{\rm s}\hat{\chi}^{\rm s}({\bm q})\hat{U}^{\rm s},
\end{equation}
\begin{equation}
  \hat{W}^{\rm o}({\bm q})=-\hat{U}^{\rm o}
  +\hat{U}^{\rm o}\hat{\chi}^{\rm o}({\bm q})\hat{U}^{\rm o}.
\end{equation}
The element of the pair correlation function
$\hat{\phi}({\bm k})$ is given by
\begin{equation}
\phi_{\alpha\beta,\mu\nu}({\bm k})=
T\sum_{n}
G^{(0)}_{\alpha\mu}(\bm{k},-i\omega_{n})
G^{(0)}_{\nu\beta}(-\bm{k},i\omega_{n}).
\end{equation}

We obtain $T_{\rm c}$ by solving the gap equation eq.~(\ref{gap}).
Note that $T_{\rm c}$ is defined as a temperature at which
the positive maximum eigenvalue of the gap equation becomes unity.
For the evaluation of the eigenvalue of eq.~(\ref{gap}),
we use the power method.
The first Brillouin zone is divided into $64 \times 64$ meshes and
we exploit the fast-Fourier-transformation algorithm,
in order to accelerate the sum of large amount of momenta.

As for the values of Coulomb interactions,
we note the relations of $U=U'+J+J'$ and $J=J'$,
as mentioned above.
Here we assume the value of $J$ as $J=U/6$.
Then, from the above relations, we obtain $U'=2U/3$.
In this paper, we fix the value of $U$ as $U=2$ eV.
Note that the energy unit is set as eV in this paper.
The bandwidth $W$ of the present tight-binding band structure
is $W=4.5$ eV.
Thus, the value of $U=2$ is not so large in comparison with $W$.

\section{Calculation Results}

\subsection{Phase diagram}

Let us show our calculation results for the transition temperature $T_{\rm c}$
as a function of doping $x$ in Fig.~2.
First of all, we should note the magnitude of the vertical temperature axis.
Since the energy unit is eV in the present calculations,
the maximum value of $T_{\rm c}$ becomes about 600 K,
if we simply use the present energy unit.
Here we should pay attention to the fact that
we have not included at all the effects of the retardation of effective interactions
and the quasi-particle life-time.
If we correctly include the vertex corrections in addition to above strong-coupling effects,
$T_{\rm c}$ is considered to be strongly suppressed.
Thus, it is not necessary to consider seriously the magnitude of $T_{\rm c}$
in the present calculations.
Rather we should pay our attention to the relative change of
$T_{\rm c}$ by the doping $x$.

\begin{figure}[t]

\includegraphics[width=\linewidth]{fig2.eps}
\caption{Phase diagram on the plane of doping $x$ and temperature $T$.

while solid red squares and blue diamonds indicate $T_{\rm c}$
for the extended $s$- and $d$-wave symmetries, respectively.
Note that the solid curve denotes the phase boundary, but the broken curve does not.

\end{figure}

The lower curve denotes the magnetic instability temperature $T_{\rm M}$
determined from ${\rm det}[\hat{1}-\hat{U}^{\rm s}\hat{\chi}({\bm q})]=0$.
In the present calculations, when we decrease the temperature,
the spin susceptibility always diverges prior to the orbital one
and we do not consider the orbital susceptibility.
Then, we solve the gap equation in the range of $T>T_{\rm M}$ to
consider the superconductivity induced by magnetic fluctuations
in the vicinity of the magnetic instability temperature.
Note that we cannot discuss the coexistence of magnetism and superconductivity
in the present RPA.

In Fig.~2, we immediately notice that the superconducting phase
in the weak-coupling limit appears in the wide range of the values
of doping $x$ and temperature $T$.
Roughly speaking, the shape of the curve for $T_{\rm c}$ is
similar to that for $T_{\rm M}$.
In particular, the position of the maximum $T_{\rm c}$ is exactly the same
as that of $T_{\rm M}$.
We also point out that the superconducting phase is divided into two regions:
The $d$-wave phase for $x<0.45$ and the extended $s$-wave phase for $x>0.45$.
The figure around at $x \approx 0.45$ in a magnified scale is shown in the inset of Fig.~2.
In the present calculations, in a very narrow region around at $x=0.45$,
$T_{\rm c}$ is suppressed.
Instead, we find the ferromagnetic (FM) phase in this region,
since the ordering vector is found to be ${\bm q}=(0,0)$ in this region.
Near $x=1.0$, $T_{\rm M}$ becomes zero since both $U$ and
the density of states at the Fermi level are small in this case,
but $T_{\rm c}$ keeps a large value,
although it is smaller than the peak value at $x=0.6$.
For $x<0.2$, we cannot obtain both magnetic and superconducting phases
in the RPA for the system with small electron densities.

We note that there is not significant structure in $T_{\rm c}$
around at $x=0.52$, at which the Fermi-surface topology is
changed due to the appearance of the Fermi-surface curves
originating from the A band.
We deduce that the effect of the pairing in the A band will not
be so significant,
since the superconductivity occurs mainly in the B band.
In the $d$-wave phase, except for the narrow region around at $x=0.45$,
$T_{\rm c}$ is increased with the increase of $x$.
On the other hand, in the extended $s$-wave phase, $T_{\rm c}$ takes
a broad peak at $x=0.6$.
Note that the magnetic instability curve also exhibits the peak at $x=0.6$,
but the peak structure is rather sharp.

Let us now compare our phase diagram with experimental results.
First we briefly review the experimental facts.
For LaO$_{1-x}$F$_x$BiS$_2$,
the doping dependence of $T_{\rm c}$ seems to be sensitive to
the way of sample synthesis \cite{Mizuguchi4,Deguchi,Higashinaka}.
For as-grown samples, $T_{\rm c}$ is increased between $x=0.2$ and $0.5$,
whereas it becomes almost constant between $x=0.5$ and $0.7$.
For annealed samples under high pressures,
$T_{\rm c}$ is totally increased and it becomes maximum at $x=0.5$.
In addition, $T_{\rm c}$ seems to be abruptly increased
between $x=0.4$ and $0.5$.

For NdO$_{1-x}$F$_x$BiS$_2$, we have found weak
doping dependence of $T_{\rm c}$ \cite{Demura}.
It has been found that superconductivity appears in the region of
$0.1 \le x \le 0.7$ and $T_{\rm c}$ becomes maximum at $x=0.4$,
although the change of $T_{\rm c}$ by doping $x$ is not so significant
in comparison with LaO$_{1-x}$F$_x$BiS$_2$.

In our phase diagram, the maximum $T_{\rm c}$ is found at $x=0.6$,
which is deviated from $x=0.5$ for LaO$_{1-x}$F$_x$BiS$_2$
and $x=0.4$ for NdO$_{1-x}$F$_x$BiS$_2$.
This deviation may be explained by the strong coupling calculation
or by the further inclusion of electron-phonon interaction.
These points will be discussed in future.
We remark a point that the nominal value of $x$ may be deviated
from the amount of electron doping in BiS$_2$ layer \cite{Mizuguchi5}.
We should pay due attention to this point in the comparison with
experiments. It is another future task.

Around at $x=0.45$, the Fermi-surface topology is changed
and the singlet superconductivity has been found to be suppressed.
As expected from the FM phase around at $x=0.45$,
the eigenvalue of the triplet pair has been found to be larger than
that of the singlet one in this region, although it has not
reached the unity in the present calculation.
The tendency of the triplet pair may be also related to the previous
work in Ref.~\cite{Yang}.
When we include the strong-coupling effects and the vertex corrections
in the evaluation of the normal and anomalous self-energies,
the triplet superconductivity may occur around at $x=0.45$.
This is one of interesting future issues.

\subsection{Susceptibilities and Fermi-surface curves}

In order to grasp the kind of the magnetic fluctuations for the pair formation,
we show the spin susceptibilities in the RPA
for $x=0.3$, $0.4$, $0.5$, and $0.6$ in Figs.~3 and 4
along the path of $\bm{q}=(0,0)$$\rightarrow$$(\pi,0)$
$\rightarrow$$(\pi,\pi)$$\rightarrow$$(0,0)$.
Since we have found that orbital susceptibilities are totally suppressed
and they do not show any significant structures in comparison with spin ones
in the present calculations, we show only spin susceptibilities in this paper.

\begin{figure}[t]
\centering
\includegraphics[width=\linewidth]{fig3.eps}
\caption{Spin susceptibilities in the RPA
for (a) $x=0.3$ and (b) $x=0.4$.
Inset in each panel denotes the Fermi-surface curve.
}
\end{figure}

\begin{figure}[t]
\centering
\includegraphics[width=\linewidth]{fig4.eps}
\caption{Spin susceptibilities in the RPA
for (a) $x=0.5$ and (b) $x=0.6$.
Inset in each panel denotes the Fermi-surface curve.
}
\end{figure}

In Figs.~3(a) and 3(b), we show the spin susceptibilities,
respectively, for $x=0.3$ and $0.4$.
Note that the temperatures are set as $T_{\rm c}$,
which are $T_{\rm c}=0.0255$ for $x=0.3$ and $T_{\rm c}=0.0355$
for $x=0.4$.
We find the enhanced spin fluctuations of $\bm{q}$=$(q,q)$,
which will contribute to the Cooper-pair formation for superconductivity.
The value of $q$ becomes small when $x$ is increased from $0.3$ to $0.4$.
For $x=0.4$, we observe another small peak for large $q$.
Note that the FM fluctuations also grow for $x=0.4$
in comparison with that for $x=0.3$.
The FM fluctuations tend to be significant, when $x$ approaches $0.45$,
as expected from the existence of the FM phase around at $x=0.45$.

In Fig.~4(a) and 4(b), we exhibit the spin susceptibilities in the RPA
for $x=0.5$ and $0.6$, respectively.
Note that the temperature is set as $T=0.0445$ and $0.0565$,
which are equal to $T_{\rm c}$ at $x=0.5$ and $0.6$, respectively.
In the bare susceptibility, the maximum peak appears at $\bm{q}=(q, 0)$ with small $q$.
This peak structure is due to the nesting of a couple of large Fermi-surface curves
with the centers at the $\Gamma$ and M points \cite{Martins}.
In fact, for $x=0.5$, the peak  at $\bm{q}=(q, 0)$ is larger than other peak values
in the RPA spin susceptibility, although anti-ferromagnetic (AF) spin fluctuations also grow.
For $x=0.6$, the peak at $\bm{q}=(q, 0)$ is still significant,
but we observe a clear peak at $\bm{q}=(\pi, \pi)$,
suggesting AF spin fluctuations.
We deduce that the evolution of the AF spin fluctuations
is closely related to the elevation of $T_{\rm c}$
from $x=0.5$ to $x=0.6$.

\subsection{Gap functions and Fermi-surface curves}

Now we show the results of the gap function
for the Cooper pair from the same band,
$\Delta_{\rm A}(\bm{k})$ and $\Delta_{\rm B}(\bm{k})$,
which are obtained by the appropriate linear combinations
of $\Delta^{\rm S}_{11}({\bm k})$, $\Delta^{\rm S}_{22}({\bm k})$,
$\Delta^{\rm S}_{12}({\bm k})$, and $\Delta^{\rm S}_{21}({\bm k})$.
There exist the components of the Cooper pairs formed by different band electrons,
but we do not show them here, since their magnitudes are small
in comparison with those of the same band.
Note also  that only the singlet pair has been stabilized,
although we have investigated both singlet and triplet channels.
Thus, we show here the results for singlet gap functions.

\begin{figure}[t]
\centering
\includegraphics[width=\linewidth]{fig5.eps}
\caption{
(a) $\Delta_{\rm A}(\bm{k})$ and (b) $\Delta_{\rm B}(\bm{k})$ for $x=0.3$.

}
\end{figure}

\begin{figure}[t]
\centering
\includegraphics[width=\linewidth]{fig6.eps}
\caption{
(a) $\Delta_{\rm A}(\bm{k})$ and (b) $\Delta_{\rm B}(\bm{k})$ for $x=0.4$.
We show the Fermi-surface curves in the figure.
}
\end{figure}

\begin{figure}[t]
\centering
\includegraphics[width=\linewidth]{fig7.eps}
\caption{
(a) $\Delta_{\rm A}(\bm{k})$ and (b) $\Delta_{\rm B}(\bm{k})$ for $x=0.5$.
We show the Fermi-surface curves in the figure.
}
\end{figure}

\begin{figure}[t]
\centering
\includegraphics[width=\linewidth]{fig8.eps}
\caption{
(a) $\Delta_{\rm A}(\bm{k})$ and (b) $\Delta_{\rm B}(\bm{k})$ for $x=0.6$.
We show the Fermi-surface curves in the figure.
}
\end{figure}

In Figs.~5, we exhibit $\Delta_{\rm A}(\bm{k})$
and $\Delta_{\rm B}(\bm{k})$ for $x=0.3$ and $T=0.0255$
by using the color gradation to visualize the momentum
dependence at a glance.
First we notice that the gap functions $\Delta_{\rm A}(\bm{k})$
and $\Delta_{\rm B}(\bm{k})$ possess the $d$-wave symmetry,
which is characterized by the sign change of the gap for the interchange
of $k_x$ and $k_y$.
In this doping, there is no Fermi-surface curve from the band A,
but we observe the significant amplitude around at the X and Y points,
since the band A is near the Fermi level on these points,
as shown in Fig.~1(a).

As for the gap function on the band B in Fig.~5(b),
we observe that the nodes of the $d$-wave, $k_x=\pm k_y$,
are running between the pocket-like Fermi-surface curves.
Namely, the nodes do not cross the Fermi-surface curves.
However, we find the sign change of the gap at the heads
of the projections for the interchange of $k_x$ and $k_y$.
Note that the signs of the gap functions near the X and Y points are
also different from those at the heads of the projections
of the Fermi-surface curves.
For $x=0.3$, we can observe other node lines connecting
the points of $(-\pi,0)$, $(0,-\pi)$, $(\pi,0)$, and $(0,\pi)$.
These node structures seem to be consistent with those proposed
by Usui {\it et al.} \cite{Usui}.

In Figs.~6, we show $\Delta_{\rm A}(\bm{k})$
and $\Delta_{\rm B}(\bm{k})$ for $x=0.4$ and $T=0.0355$.
The $d$-wave node structure is similar to that in Figs.~5,
but we do not observe the node lines connecting four points of
$(-\pi,0)$, $(0,-\pi)$, $(\pi,0)$, and $(0,\pi)$ in Fig.~6(b).
Rather the gap function $\Delta_{\rm B}(\bm{k})$ changes
its sign for three times on the straight line from $(\pi,0)$ to $(0,\pi)$.
The gap function $\Delta_{\rm B}(\bm{k})$ seems to includes
the components of the symmetry higher than the $d$-wave,
for instance, $g$-wave \cite{Wu}.

The gap structure on the Fermi-surface curves
around at the X and Y points has been investigated
in NdO$_{0.71}$F$_{0.29}$BiS$_2$ with the use of
an angle-resolved photoemission spectroscopy \cite{Ota}.
The large anisotropy has been observed and
the gap size on the point at which the Fermi-surface curve
crosses the line from $(\pi, 0)$ to $(\pi,\pi)$ is smaller than
that on the point at which the Fermi-surface curve
crosses the line from $(\pi, 0)$ to $(0,\pi)$.
The tendency seems to agree with the present results,
but in order to conclude the existence of the node,
it is necessary to perform further experimental and theoretical
investigations.

Next we consider the gap functions for $x >0.45$.
In Fig.~7(a) and 8(a), we depict the gap functions $\Delta_{\rm A}(\bm{k})$
for $x=0.5$ and $0.6$, respectively.
Note that for $x=0.6$, we also depict
the Fermi-surface curve originating from the A band around at the X and Y points.
In both cases, we do not find the nodes characteristic to the $d$-wave
in the gap function.
The node lines satisfying $\cos k_x +\cos k_y=0$ seem to be observed,
but it is difficult to confirm them only from this figure.

In Figs.~7(b) and 8(b), we show the gap functions $\Delta_{\rm B}(\bm{k})$
and the large Fermi-surface curves for $x=0.5$ and $0.6$, respectively.
Also in these cases, the nodes characteristic to the $d$-wave gap
cannot be observed.
Note that the structures in the gap functions are
quite similar to each other irrespective of the difference in $x$.
We find several numbers of node lines expressed as $k_y=\pm k_x+C$,
where $C$ indicates an appropriate constant.
When we change $\bm{k}$ in $\Delta_{\rm B}(\bm{k})$
along the line from the $\Gamma$ to M points,
the gap changes its sign for several times.

We remark that the Fermi-surface structure becomes different
between $x=0.5$ and $0.6$.
In particular, the curvature of the Fermi-surface curves for $x=0.5$
is larger than that for $x=0.6$.
Since the nodes are well expressed by the lines of $k_y=\pm k_x+C$,
the nodes of the gap easily appear on the Fermi-surface curves
with large curvature for $x=0.5$ in comparison with those for $x=0.6$.
From Figs.~7 and 8, there seems to occur a peculiar possibility
that the Fermi-surface curves tend to
avoid the extended $s$-wave gap functions with large amplitude.
This issue should be investigated in detail in future.

\section{Discussion and Summary}

In this paper, we have solved the gap equation to obtain the
superconducting transition temperature $T_{\rm c}$
and the gap function within the RPA
on the basis of the two-band Hubbard model
for BiS$_2$-based layered compounds.
When the topology of the Fermi-surface curves
of the B band drastically changes around at $x=0.45$,
we have observed the change of the symmetry
of the gap function.
For $x<0.45$, we have obtained the $d$-wave gap with the nodes
on the lines of $k_x=\pm k_y$, which do not cross the Fermi-surface
curves with the pocket-like disconnected shapes around at the X and Y points.
On the other hand, for $x>0.45$, we have found the extended $s$-wave gap.
An interesting issue is that the amplitude of the gap seems to be small or zero
on the Fermi-surface curves.

The effect of the nodes on the temperature dependence of
physical quantities is quite interesting
for the comparison with experimental result.
In particular, it has been reported that the temperature dependence of
the penetration depth indicates the $s$- or extended $s$-wave gap
both for $x=0.3$ and $0.5$ in NdO$_{1-x}$F$_x$BiS$_2$ \cite{Jiao}.
In the present results, we have found the $d$-wave gap for $x<0.45$,
but the main nodes of $d$-wave gap do not cross the Fermi-surface curve.
For $x>0.45$, we have obtained the extended $s$-wave gap.
However, for both gap functions, we have found the node structure
on the Fermi-surface curves depending on the doping $x$.
It is interesting to clarify the temperature dependence
of the penetration depth for the gap function with the present node structure.
This is one of future problems.

In the present calculations, we have considered only the Coulomb interactions.
However, around at the Lifshitz transition point
at which the Fermi-surface topology is abruptly changed,
the coupling between the charge fluctuations and lattice vibrations
seems to be important.
In fact, the role of phonons in BiS$_2$-based materials has been
discussed intensively \cite{Yildirim,Wan,Li}.
We believe that it is necessary to include electron-phonon interaction
to the present two-orbital Hubbard model.
It is another future problem.

In summary, we have discussed the gap symmetry of
BiS$_2$-based layered superconductors by analyzing
the two-orbital Hubbard mode within the RPA.
For $x<0.45$, we have found the $d$-wave gap on the pocket-like
disconnected Fermi-surface curves, whereas for $x>0.45$,
the extended $s$-wave gap has been found on
a couple of large Fermi-surface curves with the centers at the
$\Gamma$ and M points.
The symmetry change in the gap function is believed to
be induced by the topological change in the Fermi-surface structure.

Inclusivity reigns with opening of two new cultural centers
Postedby Gray Bouchat
On Nov. 2, Portland State celebrated the grand opening of two new Cultural Resource Centers: the Pan-African Commons and the Pacific Islander, Asian & Asian American Student Center. Hosted in the Smith Memorial Student Union Ballroom, the event focused on inclusivity and identity for international and minority students.
The ballroom was crowded with excited students and faculty. The night consisted of several keynote speakers, including Professor Judy BlueHorse Skelton, a senior instructor of indigenous nations studies. She prayed for good energy and gave thanks for the opening of the new centers.
Other keynote speakers included Vice President of Global Diversity and Inclusion Carmen Suarez, Ph.D., Executive Director of the Cultural Resource Centers Cynthia Gomez and PSU President Wim Wiewel. An American Sign Language interpreter accompanied each speaker.
Shanice Clarke, program coordinator for Pan-African Commons, believes the new centers will help the inclusivity of PSU.
"The momentous additions of the [PIAAA] Student Center and Pan-African Commons will be a formative transition for PSU students," Clarke said. "Students who identify with the center will have a place to unapologetically be themselves and have their identities affirmed and embraced in their learning experiences as PSU students."
The Pacific Islanders Scholar Band performed "E Papa Waiari" and "Ku'u Aloha." The Delta Sigma Theta Sorority, Inc. also performed, clapping beats in name the of the new centers and the upcoming election.
Clarke also believes that the expanding cultural centers will help with the isolation some students of color might feel on campus. "We will gain a dedicated area to give resources, programs and advocacy to support the retention of students," she said.
At these centers, students will be able to develop their identity within their own culture—a home away from home. "The Cultural Resource Centers carry a value for social justice, and we aim to be critical of the contexts and environments in which we navigate in our own cultures," Clarke said.
Makerusa Porotesano, program coordinator for the PIAAA Center, commented on the naming process of the new resource centers. "I think the simplicity and inclusiveness of the names were attractive to a lot of students," Porotesano said. "We had a lot of creative names to choose from, with the variety of cultures, languages, and geographical differences in our communities. I think making sure everyone was included was most important."
Porotesano believes the centers will help students further develop their identities and feel comfortable in their own space. "Every center has something unique to offer, but we all have the same learning goals. People who use our centers will learn the different ways we offer community space, service and relationships."
Those interested in joining either center can email [email protected] The Pan-African Commons is currently open and located in SMSU 236. The PIAAA Center will open in November in SMSU 235.

Policymakers Take Important Steps to Protect District Residents During Corona Virus Pandemic
Posted by Damon King on Mar 23, 2020 in Blog
Last Tuesday, the D.C. Council passed the COVID-19 Response Emergency Amendment Act of 2020. This emergency legislation, which passed unanimously, takes several key steps to protect District residents in the midst of the current Corona Virus Pandemic. Last week, my Legal Aid colleagues shared their analyses of the Act, highlighting key protections for residents participating in social safety net programs and tenants, while also discussing the work that District agencies and the Council still need to do to address residents' needs. Take a look at what they have to say below:
Public Benefits Law Unit Senior Staff Attorney Drake Hagner discusses the Act's changes to Unemployment Insurance. These changes should make the program more accessible to workers who lose their jobs due to a variety of COVID-19-related events.
Public Benefits Law Unit Senior Staff Attorney Chelsea Sharon highlights the Act's broader changes to public benefits programs, including language that allows the Mayor to grant extensions for a range of safety net programs, including SNAP (food stamps), TANF, and the DC Health Care Alliance during the current public health emergency. Chelsea also expresses our hope that D.C.'s Department of Human Services will process new applications for the programs quickly and maintain enough capacity at its Call Center to serve residents who need the agency's help.
Housing Law Unit Supervising Attorney Beth Harrison discusses the Act's protections for tenants, including language that stops landlords from carrying out evictions or charging late fees during the emergency. The Act also stops utility shut-offs, including electricity, water, and gas. Beth also emphasizes the importance of funding Emergency Rental Assistance in the District's upcoming fiscal year 2021 budget so that households who suffer financial hardships during the pandemic do not ultimately lose their homes.
Consumer Law Unit Supervising Attorney Jennifer Lavallee identifies an important gap in the Act: It's failure to stop foreclosure auctions during the public health emergency. There are serious consequences that could flow from this failure and we hope that the Council will correct this in future emergency legislation.
Legal Aid is monitoring implementation of the Act and continues to be in touch with the D.C. Council about areas where further action is needed. We appreciate the work that both the Mayor and the Council have done so far to protect District residents in this difficult time and we look forward to working with policymakers to address the range of ways in which this pandemic is affecting members of our client community.

We may never get to play the long, long-awaited Half-Life 3, or Half-Life 2: Episode 3, or whatever Valve once had planned for the future of its legendary series. But we might now know how its story would have unfolded.
There was once a plan to flesh out Half-Life 2 with multiple episodes. Valve itself created Episode One and Two. It announced a third. But this third episode, and others from other developers, failed to materialise as Half-Life 2 follow-ups were lost to the sands of time and became myth.
One of these non-Valve developed episodes was once in the works at Junction Point, the studio founded by legendary game maker Warren Spector (Deus Ex, System Shock). Spector has spoken of this before, telling Game Informer Junction Point was working on an episode "that would fill in one of the gaps in the Half-Life story".
On 22nd May 2006, Valve put out a press release promising an episodic trilogy for Half-Life 2. Eurogamer wrote a news story, authored by one Ellie Gibson, with the headline: "Half-Life Episode 3 confirmed."
Half-Life writer Marc Laidlaw has left Valve after 18 years at the company.
Combine it with the main game.
A new fan-made mod, Half-Life 2: Update, will be released for free on Steam tomorrow.
The Valve-blessed add-on brings improved lighting, effects, textures and bug fixes to the first-person shooter classic.
This will be the final version of Half-Life 2: Update, which was previously made available in earlier forms outside of Steam.

Half-Life 2 mod Minerva - the project that landed Adam Foster a job at Valve - will be added to Steam later today, and will be free.

Steam group A Call for Communication (Half-Life), which boasts more than than 29,500 members, has organised a huge Half-Life 2 play session this weekend, designed to raise awareness of its campaign by boosting the game up Steam's most-played list.
The fan collective aims to encourage information from Valve on when the Half-Life series might return, be that in the form of Half-Life 2: Episode 3 or a fully-fledged Half-Life 3.
More than 10,000 gamers have joined the Steam Group campaigning for more Half-Life communication from Valve.
Half-Life 2: Episode 3 code in Dota 2?
Code possibly belonging to Half-Life 2: Episode 3 has been spotted in the leaked beta client for Dota 2.
Valve's Half-Life dev hampered by Steam?
Impulse maker Stardock draws parallels.
Steam today represents a billion-dollar operation staffed by hundreds. But has the platform's meteoric rise restricted Valve's capacity to actually create games?
Should remedy many of the problems.
EA has sneakily released a beefy patch to address problems with The Orange Box on PS3.
The 1.10 update is 128 MB, and unhelpfully has no associated documentation to outline the changes.
Early reports suggest friends not appearing on lists and certain accounts not connecting to the EA servers should no longer be a problem.
Those of you with brains like computers will probably have worked out that you can use your Portal gun in other Source-powered games like Half-Life 2 and its pair of episodes.
Valve has released statistics demonstrating how much time's been spent playing Half-Life 2: Episode 1, the nature of the game-sessions and things like how many people used the option to listen to in-game commentary.
Half-Life 2: Episode One is available now through Valve's digital distribution system Steam.
With Half-Life 2: Episode One set for release on Steam today at 6pm UK time, Valve's sent out a fourth in its series of teaser trailers, again featuring the lovely Alyx Vance - this time accompanied by her mechanical pal Dog.
With Half-Life 2: Episode 1 due to launch on Steam tomorrow, Valve's released a couple more teaser trailers to get you in the mood.
Plus: trailer for Ep 1 now showing.
Valve has confirmed that Half-Life 2: Episode One will go on sale on June 1st via the Steam download service, priced at $19.99.
Once again you play as Dr Gordon Freeman, but this time you get to explore the world outside City 17 together with the lovely Alyx Vance and her robot, Dog. It's said to offer between four and six hours of gameplay, and the good news is you don't need the original game to play. There's a teaser trailer now showing on Eurogamer TV.
Episode One will also offer a sneak peek at Episode Two, which is due to be released by the end of the year. And Valve has confirmed that a third instalment is in development - apparently "Episode One is the first in a trilogy of episodes that will conclude by Christmas 2007," don't you know.
Valve's announced that Half-Life 2: Episode One is now available to pre-purchase and pre-load on Steam.
EA's released a new video of Half-Life 2: Episode One in action - and we've whacked it up on Eurogamer TV for you to check out.
While Gabe Newell talks story.
Half-Life 2: Episode One is now due out on May 31st according to Valve, although it'll still launch simultaneously on Steam and at retail, priced $19.99.
Content will be 'richer' too.
Half-Life 2: Episode 1 won't actually require Half-Life 2 to play, Valve's explained, and although the game will be "four to six hours" long, marketing director Doug Lombardi reckons it's "markedly richer" in terms of content quality.
Valve's reportedly confirmed that the second in its episodic series of Half-Life 2 expansion is already underway.
Half-Life 2 Aftermath is no more: Valve's renamed it Half-Life 2 Episode One.
And pricing, platinum pack news.
Valve has confirmed that it aims to release Half-Life 2: Aftermath on April 24th, along with a Platinum edition of Half-Life 2.
Aftermath, announced last year, is the first single-player expansion for Half-Life 2 to expand on the events of the game, and had previously been down for a November 2005 "launch window".
Speaking to various organisations yesterday, however, Valve's Doug Lombardi said, "We're currently targeting April 24th for the release of both Aftermath and Platinum."
Valve's admitted that Half-Life 2 expansion pack Aftermath won't be with us until early 2006.
Expounds expansion a little bit.
Valve has started trailing Half-Life 2 expansion Aftermath ahead of its September release. The video is more of a teaser really, and hints at darker themes (and, as if to illustrate this, is also really quite dark and at points hard to make out).
We can see "stalkers", which seem to be rather unpleasant, and Alyx features heavily - including a shot of her putting down an Antlion, presumably an unfriendly one. It's an act that reminds us we haven't mentioned the Antlion Troopers Deuce mod yet. Now we have. Go Antlions!
Half-Life 2: Aftermath, of course, deals with the what-happens-after of City 17's Gordon Freeman-instigated downfall, picking up as the city starts to crumble. It's part of a larger canon of post-HL2 work that Valve's undertaking, which also includes Source Engine remakes of popular Half-Life 1 modifications like Day of Defeat and The Lost Coast, which reshapes a coastal section of Half-Life 2 using (more) advanced graphical techniques like High Dynamic Range (HDR).
More HL2 goodness coming soon.
Valve's Robin Walker has revealed a smattering of new details about Aftermath, the forthcoming Half-Life 2 expansion pack that most PC gamers with a pulse will be adding to their collection later this year.
And Valve is currently shooting for a September release.
Half-Life 2 expansion Aftermath will be getting a retail release after all, Valve's Doug Lombardi has confirmed, and the developer aims to release the game in September.
Speaking to Eurogamer at E3, Lombardi said: "Aftermath will be coming out at retail, but we're finalising our publishing partner." Valve recently parted ways with Half-Life 2 publisher Vivendi-Universal Games, who will cease distribution of the company's products at the end of August.
Asked when the developer's new publishing partner was likely to be revealed, Lombardi said it would be "soon, in the summer". He also added that the current release date estimate for Aftermath is "September".
It's a weighty download, mind, but very pretty indeed. On Eurofiles now.
A new trailer for Half-Life 2: The Lost Coast is now available for download from good old Eurofiles.
It might take a while to download at 179MB, and you only get a minute's worth of footage for all that, but what pretty footage it is - the trailer is designed to show off the High-Dynamic Range rendering that's being used in the expansion.
You can read a full preview of Half-Life 2: Lost Coast here.
For those of you who haven't glanced right lately, we've got some PC FPS treats.
For those of you whose necks don't turn more than half an inch left or right of centre, and whose eyes tunnel straight to the point without worrying about what's going on in the periphery - in other words, for those of you who haven't bothered looking at the news column today - you'll be interested to learn that screenshots of both Quake IV and Half-Life 2: Aftermath have now emerged. One of each.
