Time-dependent photospheric radiative transfer in structured GRB jets: spectral evolution and polarization diagnostics
Photospheric emission from relativistic gamma-ray burst (GRB) jets is a promising mechanism for producing the Band-like spectra observed in the prompt phase, yet the connections between jet structu...

Distribution-free screening of spatially variable genes in spatial transcriptomics
Spatial transcriptomics (ST) technologies enable transcriptome-wide gene expression profiling while preserving spatial resolution, offering unprecedented opportunities to uncover complex spatial st...

AgroDesign: A Design-Aware Statistical Inference Framework for Agricultural Experiments in Python
Statistical analysis of agricultural experiments is based on structured experimental designs such as randomized block, factorial, split-plot, and multi-environment trials. While the theoretical bas...

Critical stationary fluctuations in reaction--diffusion processes
We study stationary fluctuations at criticality for a one-dimensional reaction--diffusion process combining symmetric simple exclusion dynamics with Glauber-type spin flips. The strength of the Gla...

Automating Detection and Root-Cause Analysis of Flaky Tests in Quantum Software
Like classical software, quantum software systems rely on automated testing. However, their inherently probabilistic outputs make them susceptible to quantum flakiness -- tests that pass or fail in...

Lockbox -- A Zero Trust Architecture for Secure Processing of Sensitive Cloud Workloads
Enterprises increasingly rely on cloud-based applications to process highly sensitive data artifacts. Although cloud adoption improves agility and scalability, it also introduces new security chall...

Impermanent: A Live Benchmark for Temporal Generalization in Time Series Forecasting
Recent advances in time-series forecasting increasingly rely on pre-trained foundation-style models. While these models often claim broad generalization, existing evaluation protocols provide limit...

Exp-Force: Experience-Conditioned Pre-Grasp Force Selection with Vision-Language Models
Accurate pre-contact grasp force selection is critical for safe and reliable robotic manipulation. Adaptive controllers regulate force after contact but still require a reasonable initial estimate....

Context-free Self-Conditioned GAN for Trajectory Forecasting
In this paper, we present a context-free unsupervised approach based on a self-conditioned GAN to learn different modes from 2D trajectories. Our intuition is that each mode indicates a different b...

Divide and Predict: An Architecture for Input Space Partitioning and Enhanced Accuracy
In this article the authors develop an intrinsic measure for quantifying heterogeneity in training data for supervised learning. This measure is the variance of a random variable which factors thro...

UNBOX: Unveiling Black-box visual models with Natural-language
Ensuring trustworthiness in open-world visual recognition requires models that are interpretable, fair, and robust to distribution shifts. Yet modern vision systems are increasingly deployed as pro...

Secondary gravitational waves against a strong gravitational wave in the Bianchi VI universe
A proper-time method for constructing models of dynamic gravitational-wave fields is presented. Using the proper-time method, analytical (not numerical) models of secondary gravitational waves are ...

Query-Guided Analysis and Mitigation of Data Verification Errors (Extended Version)
Data verification, the process of labeling data items as correct or incorrect, is a preprocessing step that may critically affect the quality of results in data-driven pipelines. Despite recent adv...

RESAPLE: An Approximate One-Step Restricted Likelihood Estimator of Spatial Dependence for Exploratory Spatial Analysis
Diagnostics such as Moran's index and approximate profile likelihood-based estimators (APLE) for Gaussian spatial autoregressive models are widely used in exploratory data analysis to assess the st...

Bilevel Planning with Learned Symbolic Abstractions from Interaction Data
Intelligent agents must reason over both continuous dynamics and discrete representations to generate effective plans in complex environments. Previous studies have shown that symbolic abstractions...

The Grasshopper Problem on the Sphere
The spherical grasshopper problem is a geometric optimization problem that arises in the context of Bell inequalities and can be interpreted as identifying the best local hidden variable approximat...

Drift-to-Action Controllers: Budgeted Interventions with Online Risk Certificates
Deployed machine learning systems face distribution drift, yet most monitoring pipelines stop at alarms and leave the response underspecified under labeling, compute, and latency constraints. We in...

Multi-epoch afterglow rebrightenings in GRB 250129A: Evidence for successive shock interactions
Most long gamma-ray bursts (GRBs) exhibit afterglows broadly consistent with external forward-shock emission, typically described by smooth broken power-law decays in the multiband light curve. How...

Emergence of an Advective Boundary Layer in Monsoon Cross-Equatorial Flow: Scaling, Dynamics, and Idealized Models
The conventional Ekman model of the tropical boundary layer neglects nonlinear momentum advection and breaks down near the equator, where Coriolis effects are weak. During South Asian monsoon onset...
