Florida agency tells newspaper to halt reporting angle on foundation associated with governor's wife
Florida’s child welfare agency has sent a letter to a newspaper telling it to “cease and desist” its reporting on foster families for a story about a nonprofit associated with Gov. Ron DeSantis’ wife. The foundation is the subject of an investigation. The Orlando Sentinel received the letter on Friday from the Department of Children and Families. The letter claims the newspaper’s Tallahassee reporter intimidated foster families who had received money from the Hope Florida Foundation w…

Combinatorics of descent algebras and graph coverings
We give a direct combinatorial proof that the product of two descent classes in a symmetric group is a sum of descent classes. The proof is based on the fact that the group product gives a covering map when descent classes are endowed with the graph structure coming from the weak order. The main geometric argument is valid for any Coxeter group, even infinite ones for which the descent algebra does not exist.

Bittensor Protocol: The Bitcoin in Decentralized Artificial Intelligence? A Critical and Empirical Analysis
This paper investigates whether Bittensor can be considered the Bitcoin of decentralized Artificial Intelligence by directly comparing its tokenomics, decentralization properties, consensus mechanism, and incentive structure against those of Bitcoin. Leveraging on-chain data from all 64 active Bittensor subnets, we first document considerable concentration in both stake and rewards. We further show that rewards are overwhelmingly driven by stake, highlighting a clear misalignment between qualit…

Simple Convergence Proof of Adam From a Sign-like Descent Perspective
Adam is widely recognized as one of the most effective optimizers for training deep neural networks (DNNs). Despite its remarkable empirical success, its theoretical convergence analysis remains unsatisfactory. Existing works predominantly interpret Adam as a preconditioned stochastic gradient descent with momentum (SGDM), formulated as $\bm{x}_{t+1} = \bm{x}_t - \frac{γ_t}{{\sqrt{\bm{v}_t}+ε}} \circ \bm{m}_t$. This perspective necessitates strong assumptions and intricate techniques, resulti…

On Monday, scores of scientists at the National Institutes of Health sent their Trump-appointed leader a letter titled the "Bethesda Declaration"
challenging “policies that undermine the NIH mission, waste public resources, and harm the health of Americans and people across the globe.”
It says: “We dissent.”
In a capital where insiders often insist on anonymity to say such things publicly,
92 NIH researchers, program directors, branch chiefs and scientific r…

NIH scientists go public with criticism over Trump cuts
President Donald Trump’s National Institutes of Health director says some employees’ critical letter to him has “fundamental misconceptions about the policy directions the NIH has taken.” Monday’s letter from NIH researchers and staffers says the Republican Trump administration’s policies waste public resources and harm people’s health. NIH Director Jay Bhattacharya in his confirmation hearings pledged openness to views that might conflict with his, saying dissent is the “essenc…

Dequantized particle algorithm for the nonlinear Vlasov-Poisson system
We present a dequantization algorithm for the Vlasov--Poisson (VP) system, termed the dequantized particle algorithm, by systematically dequantizing the underlying many-body quantum theory. Starting from the second-quantized Hamiltonian description, we derive a finite-dimensional dequantized system and show that it furnishes a structure-preserving discretization of the Schrödinger--Poisson (SP) equations. Through the Wigner or Husimi transformations, this discretization provides an efficient a…
