India is betting $18 billion to build a chip powerhouse. Here’s what it means
India dreams of being self-sufficient in terms of semiconductors has seen it invest heavily to attract global chip companies. But success has been uneven.

Trump administration ramps up crackdown on US visa holders
The Trump administration says it’s reviewing more than 55 million foreigners who have valid U.S. visas for any violations that could lead to deportation. In a written answer to a question from The Associated Press, the State Department said all U.S. visa holders are subject to “continuous vetting.” It says it has an eye toward any indication that they could be ineligible for permission to enter or stay in the United States. The State Department’s new language suggests that the continual…

Byzantine-Robust Decentralized Coordination of LLM Agents
Collaboration among multiple large language model (LLM) agents is a promising approach to overcome inherent limitations of single-agent systems, such as hallucinations and single points of failure. As LLM agents are increasingly deployed on open blockchain platforms, multi-agent systems capable of tolerating malicious (Byzantine) agents have become essential. Recent Byzantine-robust multi-agent systems typically rely on leader-driven coordination, which suffers from two major drawbacks. First…

Automated Constitutive Model Discovery by Pairing Sparse Regression Algorithms with Model Selection Criteria
The automated discovery of constitutive models from data has recently emerged as a promising alternative to the traditional model calibration paradigm. In this work, we present a fully automated framework for constitutive model discovery that systematically pairs three sparse regression algorithms (Least Absolute Shrinkage and Selection Operator (LASSO), Least Angle Regression (LARS), and Orthogonal Matching Pursuit (OMP)) with three model selection criteria: $K$-fold cross-validation (CV), Aka…

"They Aren't Built For Me": An Exploratory Study of Strategies for Measurement of Graphical Primitives in Tactile Graphics
Advancements in accessibility technologies such as low-cost swell form printers or refreshable tactile displays promise to allow blind or low-vision (BLV) people to analyze data by transforming visual representations directly to tactile representations. However, it is possible that design guidelines derived from experiments on the visual perception system may not be suited for the tactile perception system. We investigate the potential mismatch between familiar visual encodings and tactile perc…

Intermediate-temperature specific heat of solids and the rationale behind the Maier-Kelley empirical formula
The heat capacity of solids at intermediate-to-high temperatures is of fundamental importance to several fields ranging from geology to material science. It depends on a variety of factors, with anharmonicity and, ultimately, melting playing a pivotal role. In this work we develop a first-principles model from an analytically tractable semi-harmonic oscillator Hamiltonian. The resulting specific heat expression depends not only on the Einstein temperature of the material but also on other physi…

The New LLM Bottleneck: A Systems Perspective on Latent Attention and Mixture-of-Experts
Computational workloads composing traditional Transformer models are starkly bifurcated. Multi-Head Attention (MHA) is memory-bound, with low arithmetic intensity, while feedforward layers are compute-bound. This dichotomy has long motivated research into specialized hardware to mitigate the MHA bottleneck. This paper argues that recent architectural shifts, namely Multi-head Latent Attention (MLA) and Mixture-of-Experts (MoE), challenge the premise of specialized attention hardware. We make …

Dark matter pair absorption
We present a comprehensive analysis of the sensitivity of atomic transitions to light dark matter pair absorption. Unlike scattering, where only a fraction of the dark matter energy is deposited, pair absorption processes absorb the full mass, and are therefore capable of constraining far lighter dark matter. Spin-flip and fine structure transitions are able to constrain electroweak scale axial-vector couplings for bosonic dark matter with $μ\mathrm{eV}$ to eV masses, whilst principal quantum …

Positive density of primes of ordinary reduction for abelian varieties of simple signature
By a result of Serre, if $A$ is an elliptic curve without CM defined over a number field $L$, then the set of primes of $L$ for which $A$ has ordinary reduction has density $1$. Katz and Ogus proved the same is true when $A$ is an abelian surface, after possibly passing to a finite extension of $L$. More recently, Sawin computed the density of the set of primes of $L$ for which an abelian surface $A$ has ordinary reduction, depending on the endomorphism algebra of $A$. In this paper, we prove s…
