Improved $\ell_{p}$ Regression via Iteratively Reweighted Least Squares
We introduce fast algorithms for solving $\ell_{p}$ regression problems using the iteratively reweighted least squares (IRLS) method. Our approach achieves state-of-the-art iteration complexity, outperforming the IRLS algorithm by Adil-Peng-Sachdeva (NeurIPS 2019) and matching the theoretical bounds established by the complex algorithm of Adil-Kyng-Peng-Sachdeva (SODA 2019, J. ACM 2024) via a simpler lightweight iterative scheme. This bridges the existing gap between theoretical and practical a…

When Hallucination Costs Millions: Benchmarking AI Agents in High-Stakes Adversarial Financial Markets
We present CAIA, a benchmark exposing a critical blind spot in AI evaluation: the inability of state-of-the-art models to operate in adversarial, high-stakes environments where misinformation is weaponized and errors are irreversible. While existing benchmarks measure task completion in controlled settings, real-world deployment demands resilience against active deception. Using crypto markets as a testbed where $30 billion was lost to exploits in 2024, we evaluate 17 models on 178 time-anchore…

Was just having a conversation with someone about how "50%" of the country voted for Trump and in reminding them it's way less took the time to look up the numbers. In 2024 Trump got 77.3 million votes in a country of 340.1 million people. That's 22.7% of the people. ~21.5% of the people are under age 18, so 263.6 million adults. Trump got the vote of 29.3% of them. Some of those adults aren't eligible to vote, but when discussing social dynamics, they matter just as much, as do kids... Even of the people who voted for Trump, many were not at all MAGA fanatics (even if they at minimum had a seriously warped worldview and dangerous politics of one kind or another).
The truth is, almost no president has ever had a huge popular mandate, because our society is engineered to let a minority political class retain most of the power while giving the illusion of influence to the masses.

"One or two years that exceed 1.5°C above the pre-industrial level does not imply that the Paris Agreement has been breached. However, with the current rate of warming at more than 0.2°C per decade, the probability of breaching the 1.5°C target of the Paris Agreement within the 2030s is highly likely."

Orientation does not help with 3-coloring a grid in online-LOCAL
The online-LOCAL and SLOCAL models are extensions of the LOCAL model where nodes are processed in a sequential but potentially adversarial order. So far, the only problem we know of where the global memory of the online-LOCAL model has an advantage over SLOCAL is 3-coloring bipartite graphs. Recently, Chang et al. [PODC 2024] showed that even in grids, 3-coloring requires $Ω(\log n)$ locality in deterministic online-LOCAL. This result was subsequently extended by Akbari et al. [STOC 2025] to a…

Sharp Interface Dynamics in a Minimal Non-Reciprocal Cahn-Hilliard System
Interest in non-reciprocally coupled systems recently led to the introduction of a minimal non-reciprocally coupled Cahn-Hilliard (CH) model by Brauns and Marchetti in 2024 arXiv:2306.08868, which we refer to as the Brauns-Marchetti (BM) model. This model can be seen as a conservative counterpart to the spatially extended FitzHugh-Nagumo model. Lacking a gradient structure, the BM model was observed to exhibit interesting dynamics including traveling periodic wave-trains and other coherent stru…

We investigate the positions of various proposed sub-populations of GRBs, including those with and without…

Further testing the validity of generalized heterogeneous-elasticity theory for low-frequency excitations in structural glasses
In a recent paper E. Lerner and E. Bouchbinder, Phys. Rev. E {\bf 111}, L013402 (2025) raised concerns regarding the validity of the theory and the interpretation of the data, presented in our previous study on non-phononic vibrational excitations in glasses, W. Schirmacher {\it et al.}, Nature Comm. {\bf 15}, 3107 (2024). In that work, we presented evidence suggesting that the commonly observed low-frequency regime of the non-phononic vibrational density of states (DoS) is, in fact, high…

How much are LLMs changing the language of academic papers after ChatGPT? A multi-database and full text analysis
This study investigates how Large Language Models (LLMs) are influencing the language of academic papers by tracking 12 LLM-associated terms across six major scholarly databases (Scopus, Web of Science, PubMed, PubMed Central (PMC), Dimensions, and OpenAlex) from 2015 to 2024. Using over 2.4 million PMC open-access publications (2021-July 2025), we also analysed full texts to assess changes in the frequency and co-occurrence of these terms before and after ChatGPT's initial public release. Acro…

State-Dependent X-ray Variability in Cygnus X-1: A 12-Year NuSTAR Timing Study of Accretion Flow Geometry
We present a comprehensive timing analysis of the black hole X-ray binary Cygnus X-1 using 26 NuSTAR observations spanning 2012-2024, providing the most detailed characterization to date of its accretion flow variability across spectral states. Our analysis reveals fundamental insights into the physics governing state transitions in stellar-mass black holes. We discover distinct bimodal flux distributions in the 8-79 keV band with well-separated peaks, contrasting with overlapping distributions…

Probing spectral variability in NGC 4490 ULX-8 over 24 years of XMM-Newton, Chandra and Swift-XRT observations
We present comprehensive spectral and timing results of 14 Chandra, 6 XMM-Newton and 19 Swift-XRT observations of the ultraluminous X-ray source NGC 4490 ULX-8, spanning from 2000 to 2024. We model the source spectra using absorbed power-law and absorbed multicolour disc blackbody models. The best-fit photon indices span 0.92-2.68, with typical uncertainties ranging from $\pm$0.1 to $\pm$1 depending on data quality. The inner disk temperature range from 0.97 to 1.69 keV, consistent with blackbo…

A Sharper View of the X-ray Spectrum of MCG--6-30-15 with XRISM, XMM-Newton and NuSTAR
We present a time-averaged spectral analysis of the 2024 XRISM observation of the narrow-line Seyfert-1 galaxy MCG--6-30-15, taken contemporaneously with XMM-Newton and NuSTAR. Our analysis leverages a unique combination of broadband and high-resolution X-ray spectroscopy to definitively isolate and characterize both broad and narrow emission and absorption features in this source. The best-fitting model for the joint spectral analysis is very well described by reflection from the inner accreti…

From X-rays to High-Energy Gamma-rays: A Comprehensive Multi-Wavelength Study of Early Gamma-Ray Burst Afterglows
Gamma-ray Bursts (GRBs) generate powerful relativistic jets that inject a large amount of energy into their surrounding environment, producing blast waves that accelerate particles to high energies. The GRB afterglow radiation provides a powerful means to investigate the microphysics of relativistic shocks and to probe the medium surrounding the progenitor of the burst. In this study, we present a comprehensive multiwavelength analysis of 31 GRBs observed between 2008 and 2024 from the Neil Geh…
