Optimal alignment of Lorentz orientation and generalization to matrix Lie groups
There exist elegant methods of aligning point clouds in $\mathbb R^3$. Unfortunately, these methods rely on the positive definite property of the Euclidean metric, and do not easily extend to the indefinite Minkowski metric. In this paper, we propose two solutions to the following problem: given inertial reference frames $A$ and $B$, and given (possibly noisy) measurements of a set of 4-vectors $\{v_i\}$ made in those reference frames with components $\{v_{A,i}\}$ and $\{v_{B,i}\}$, find the op…

On integrability of a $q$-oscillator lattice with a $B$-boundary
In this paper we propose a method of construction of a double layer-to-layer auxiliary transfer matrix defined on a half-plane with a boundary. The transfer matrix obtained has the following features: - It produces a complete set of integrals of motion, - Its ingredients can be seen as an auxiliary problem for $3d$ Kuniba-Okado reflection matrix, - The model obtained has no quantum group interpretation.

The Fourier coefficients of the critical holomorphic multiplicative chaos
The holomorphic multiplicative chaos (HMC) is a holomorphic analogue of the Gaussian multiplicative chaos. It arises naturally as the limit in large matrix size of the characteristic polynomial of Haar unitary matrices, and more generally, random matrices following the Circular-$β$-Ensemble. In a previous article, Najnudel, Paquette and Simm prove that in the $L^2$ phase $β> 4$, the appropriately normalized Fourier coefficient of the HMC converges in distribution to the square root of the tot…

GALA: Can Graph-Augmented Large Language Model Agentic Workflows Elevate Root Cause Analysis?
Root cause analysis (RCA) in microservice systems is challenging, requiring on-call engineers to rapidly diagnose failures across heterogeneous telemetry such as metrics, logs, and traces. Traditional RCA methods often focus on single modalities or merely rank suspect services, falling short of providing actionable diagnostic insights with remediation guidance. This paper introduces GALA, a novel multi-modal framework that combines statistical causal inference with LLM-driven iterative reasonin…

Balancing Preservation and Modification: A Region and Semantic Aware Metric for Instruction-Based Image Editing
Instruction-based image editing, which aims to modify the image faithfully according to the instruction while preserving irrelevant content unchanged, has made significant progress. However, there still lacks a comprehensive metric for assessing the editing quality. Existing metrics either require high human evaluation costs, which hinder large-scale evaluation, or are adapted from other tasks and lose task-specific concerns, failing to comprehensively evaluate both instruction-based modificati…

“It’s killing us”: Following workplace death, Amazon worker at JFK8 in Staten Island speaks out on unsafe working conditions
The WSWS is urging workers to take matters into their own hands and organize a rank-and-file committee to investigate this and other needless incidents at JFK8 and fight for workers’ control over safety.

Best approximation from the positive cone of an inner product lattice
Let $E$ be a directed (i.e., positively generated) ordered vector space endowed with an inner product. In this note, we prove that the following statements are equivalent: i) $E$ is a vector lattice and its norm induced by its inner product is a lattice norm. ii) The metric projection onto the positive cone $E^+$ of $E$ exists and it is both isotone and subadditive. Moreover, in this case, the best approximation to any $x \in E$ from $E^+$ coincides with its positive part $x^+$. This result ext…

Pandemic-era slump in ivory and pangolin scale trafficking persists, report finds
A recent report surveying seizures of pangolin scales and elephant ivory over the past decade has found a sharp decline following the COVID-19 pandemic. Using data from media reports, public documents, and criminal intelligence and investigations, analysts at the Wildlife Justice Commission (WJC) found authorities seized more than 370 metric tons of pangolin scales and […]
