Semafor appoints Saudi Arabia bureau chief as part of regional expansion
DUBAI: Semafor has appointed Matthew Martin as its Saudi Arabia bureau chief and global head of sovereign wealth fund coverage as the news platform expands its Gulf edition. He will head the growing team in Riyadh and be a part of the wider editorial staff led by Semafor Gulf editor Mohammed Sergie. Martin, who has over two decades of journalistic experience, was most recently Bloomberg’s chief correspondent for SWFs in the Middle East and North Africa region.

A former leader of the Education Department’s Office for Civil Rights during the Obama and Biden administrations
called the Trump administration’s targeting of undefined diversity, equity and inclusion legally spurious
and urged colleges and universities to stand up for their values.
At a panel last week at the annual Education Writers Association conference here,
Catherine Lhamon said it’s “enormously frustrating to me to see the federal government use its voice to sa…

Biden Civil Rights Chief: Trump Anti-DEI Orders Aren’t Law

Gorkov-Hedin Equations for Quantum Many-Body Systems with Spin-Dependent Interactions
Driven by the need to understand and determine the presence of non-trivial superconductivity in real candidate materials, we present a generalized set of self-consistent Gorkov-Hedin equations in a vibrating lattice with spin dependent electron-electron and electron-phonon interactions. This extends Hedin's original equations to treat quantum many-body systems where electronic and lattice correlations along with relativistic effects coexist on the same footing. Upon iterating this set of equati…

Scaling laws for doublet craters formed by low-velocity impacts of unequal-mass spheres into a granular bed
Understanding the formation mechanism of doublet craters is an important challenge for advancing knowledge in astronomy and granular physics. In this study, we investigated craters formed by low-velocity impacts of two steel spheres with different masses into a granular bed. Even when the masses were different, a figure-eight-shaped doublet crater and a central ridge were observed, similar to the case with equal masses. However, the resulting shape became asymmetric even without a time delay be…

$q$-deformed Howe duality for orthosymplectic Lie superalgebras
We give a $q$-analogue of Howe duality associated to a pair $(\mathfrak{g},G)$, where $\mathfrak{g}$ is an orthosymplectic Lie superalgebra and $G=O_\ell, Sp_{2\ell}$. We define explicitly a commuting action of a quantized enveloping algebra of $\mathfrak{g}$ and the $\imath$quantum group of $\mathfrak{so}_\ell, \mathfrak{sp}_{2\ell}$ on a $q$-deformed supersymmetric space, and describe its semisimple decomposition whose classical limit recovers the $(\mathfrak{g},G)$-duality. As special cases,…

Establishing CP Violation in $b$-Baryon Decays
It is a long-standing puzzle why the {\it CP} violation (CPV) in the baryon system has not yet been definitively established as in the meson one. We demonstrate that individual partial-wave CPV in the $Λ_b\to pπ^-$ and $pK^-$ decays can exceed $10\%$, but the destruction between the partial waves (the suppression by the small partial-wave weight) results in a small net direct CPV in the former (the latter) as measured currently. Our finding highlights the different dynamics responsible for CP…

The #MadreFire first broke out around 9:30 p.m. PT on Thursday
in a remote area of central California near Highway 166.
It quickly consumed roughly 35,000 acres overnight,
moving east-northeast onto the Carrizo Plain and burning through parts of  Los Padres National Park.
As of Friday morning, the Madre Fire was 10% contained
and had already burned about 52,592 acres of land, …
