Egocentric Tactile and Proximity Sensors as Observation Priors for Humanoid Collision Avoidance

Carson Kohlbrenner, Niraj Pudasaini, William Xie, Naren Sivagnanadasan, Nikolaus Correll, Alessandro Roncone · 2026

Collision-free motion is often aided by tactile and proximity sensors distributed on the body of the robot due to their resistance to occlusion as opposed to external cameras. However, how to shape th…

When Corrective Hints Hurt: Prompt Design in Reasoner-Guided Repair of LLM Overcaution on Entailed Negations under OWL~2~DL

Yijiashun Qi, Xiang Xu, Yuxuan Li · 2026

We report a reproducible error pattern in GPT-5.4 on OWL~2~DL compliance queries: the model frequently answers ``unknown'' when the reasoner-entailed answer is ``no'' under \emph{FunctionalProperty} c…

A divergent-beam surface plasmon resonance architecture for multiplexed malaria biosensing

Amos. S. Kiyumbi, Jordan. H. Hossea · 2026

We present a numerical study of a divergent-beam Kretschmann surface plasmon resonance (SPR) platform for multiplexed malaria biosensing. A Powell-lens-generated angular fan enables camera-based angul…

Deep Adaptive Optics Imaging Rules Out a Helium Star Companion to PSR J1928+1815

Pranav Nagarajan, Kareem El-Badry, Jim Fuller, Yunlang Guo, Thomas M. Tauris · 2026

PSR J1928+1815 is a 10.55 ms millisecond pulsar in a 3.6 hr orbit with a massive ($1.0$-$1.6\,M_{\odot}$) companion that produces extended radio eclipses. The companion, proposed to be a stripped heli…

Revisiting Conservativeness in Fluid Dynamics: Failure of Non-Conservative PINNs and a Path-Integral Remedy

Arun Govind Neelan, Ferdin Sagai Don Bosco, Naveen Sagar Jarugumalli, Suresh Balaji Vedarethinam · 2026

The choice between conservative and non-conservative formulations is a fundamental dilemma in CFD. While non-conservative forms offer intuitive modeling in primitive variables, they typically produce …

Geometric Inverse Semigroup Theory: a note on the Milnor-Schwarz Lemma for inverse monoids

Giorgio Mangioni, Francesco Tesolin · 2026

We generalise the Milnor-Schwarz lemma to inverse monoids acting on presheaves of geodesic metric spaces. We provide two proofs of this fact: one only uses elementary techniques, inspired by the argum…

Over-Refusal and Representation Subspaces: A Mechanistic Analysis of Task-Conditioned Refusal in Aligned LLMs

Utsav Maskey, Mark Dras, Usman Naseem · 2026

Aligned language models that are trained to refuse harmful requests also exhibit over-refusal: they decline safe instructions that seemingly resemble harmful instructions. A natural approach is to abl…
