Sometimes nonparametrics beat parametrics, even when the model is right
A basic issue in both teaching of and practice of statistics is the interplay between modelling assumptions and inference performance. The general message conveyed is that stronger assumptions lead...

Color image restoration based on nonlocal saturation-value similarity
In this paper, we propose and develop a novel nonlocal variational technique based on saturation-value similarity for color image restoration. In traditional nonlocal methods, image patches are ext...

Model Reference Adaptive Control For Gust Load Allevation of Nonlinear Aeroelastic
Model Reference Adaptive Control based on Lyapunov stability theory is developed for gust load alleviation of nonlinear aeroelastic systems. The controller operates on a nonlinear reduced-order mod...

Breaking Hard Isomorphism Benchmarks with DRESS
In this paper we study the single-deletion variant $Δ$-DRESS, part of the broader DRESS framework. We demonstrate empirically that $Δ$-DRESS, a single level of vertex deletion applied to the DRESS ...

ICE: Intervention-Consistent Explanation Evaluation with Statistical Grounding for LLMs
Evaluating whether explanations faithfully reflect a model's reasoning remains an open problem. Existing benchmarks use single interventions without statistical testing, making it impossible to dis...

UEPS: Robust and Efficient MRI Reconstruction
Deep unrolled models (DUMs) have become the state of the art for accelerated MRI reconstruction, yet their robustness under domain shift remains a critical barrier to clinical adoption. In this wor...

SpecForge: A Flexible and Efficient Open-Source Training Framework for Speculative Decoding
Large language models incur high inference latency due to sequential autoregressive decoding. Speculative decoding alleviates this bottleneck by using a lightweight draft model to propose multiple ...

Stability of Charge Collection Efficiency and Time Resolution in 4H-SiC PIN Diodes Under X-ray Irradiation
This study evaluates the radiation tolerance of a 4H-SiC PIN detector under X-ray irradiation up to \SI{2}{MGy} (Si) at \SI{160}{keV}. The detector features a fully epitaxial vertical PIN structure...

HEP Statistical Inference for UAV Fault Detection: CLs, LRT, and SBI Applied to Blade Damage
This paper transfers three statistical methods from particle physics to multirotor propeller fault detection: the likelihood ratio test (LRT) for binary detection, the CLs modified frequentist meth...

CoDA: Exploring Chain-of-Distribution Attacks and Post-Hoc Token-Space Repair for Medical Vision-Language Models
Medical vision--language models (MVLMs) are increasingly used as perceptual backbones in radiology pipelines and as the visual front end of multimodal assistants, yet their reliability under real c...

Beyond Passive Aggregation: Active Auditing and Topology-Aware Defense in Decentralized Federated Learning
Decentralized Federated Learning (DFL) remains highly vulnerable to adaptive backdoor attacks designed to bypass traditional passive defense metrics. To address this limitation, we shift the defens...

When Names Change Verdicts: Intervention Consistency Reveals Systematic Bias in LLM Decision-Making
Large language models (LLMs) are increasingly used for high-stakes decisions, yet their susceptibility to spurious features remains poorly characterized. We introduce ICE-Guard, a framework applyin...

Wind accretion onto planets orbiting an evolving Solar-like star and their detectability
As stars evolve, they undergo significant changes in their physical properties, which can have a profound impact on the planets orbiting them. In particular, the mass lost through stellar wind may ...

Counting Circuits: Mechanistic Interpretability of Visual Reasoning in Large Vision-Language Models
Counting serves as a simple but powerful test of a Large Vision-Language Model's (LVLM's) reasoning; it forces the model to identify each individual object and then add them all up. In this study, ...

A systematic search for physical associations between fast radio bursts and astrophysical transients
The physical origin of fast radio bursts (FRBs) remains an unsolved mystery in astrophysics, with the magnetar central engine model as the leading framework. Systematically searching for physical a...

$d_{N Ω}$ production in $Ωd$ scattering process
In the present work, we propose to investigate the production of $d_{N Ω}$ in the $Ω^{-} d \rightarrow p d_{N Ω}^-$ process by utilizing an effective Lagrangian approach, where $d_{N Ω}$ is identif...
