Temporal Gradient Inversion for Private Trajectory Reconstruction in Embodied Reinforcement Learning
A temporal gradient-inversion attack reconstructs private robot observation-action traces from the policy gradients those agents send to a server.

Quantum Feature Selection for Biomedical Data Analysis
A QUBO feature-selection recipe for metabolomics is run on gate-based quantum hardware and compared with classical methods — without claiming quantum advantage.

SemMSA: Latent Semantic-Aided Robust Multimodal Sentiment Analysis with Incomplete Data
A latent-semantic multimodal sentiment model uses a frozen LLM and spectral alignment so missing video or audio is less likely to invent fake cues.

Learning and interpreting policies for simultaneous entanglement requests in quantum networks
A graph-aware deep RL policy schedules simultaneous entanglement jobs on quantum networks and still works when links fire much less often than heuristic rules…

Agentic Detection of Online Conspiracies
An agent that queries social context outperforms text-only models at telling conspiracy endorsement from satire, criticism, or concern — on a huge Hebrew tweet…

PFArena: Benchmarking Language Models for Protein Modification
A four-scenario benchmark shows protein language models, general LLMs, and agents win different protein-mutation jobs depending on how much wet-lab fitness dat…

Topological Inference for Organoids
A topology-plus-simulation pipeline infers hidden physical parameters of pancreatic organoid lumina from images, including a single snapshot.

Self-Adaptive VLA for Robust Robot Deployment
A vision-language-action policy adapts on the fly to worn or miscalibrated hardware by treating its own recent rollouts as context, without a technician recali…

Evaluating Cross-region Generalization for Wavelet-Diffusion Precipitation Downscaling
A wavelet diffusion model trained only on Oklahoma still helps downscale radar-like precipitation elsewhere, and a spatial-clumpiness score predicts when it wi…

TrackEverything: Long Horizon Dense Tracking via De-Duplicating 3D Scene Representations
A 3D point tracker follows every visible point for more than a thousand frames inside 40 GB of GPU memory by storing the world once, not the whole video twice.

Projected amorphous topological insulators
Theory work shows that randomly keeping only a fraction of a crystal’s sites can still leave a quantized topological insulator after the leftover sites are int…

The Moreau-Yosida approximation of the Entanglement of Formation: basic properties and accuracy estimates
A family of smoother stand-in functions climbs toward the Entanglement of Formation, with explicit error bars — and the author notes ChatGPT helped write secon…

Deep HST/STIS Coronagraphic Imaging of the $β$ Pictoris Debris Disk: On the Scattered Light Component of the Cat's Tail
Hubble finally sees the visible/near-IR glow of β Pictoris’s “Cat’s Tail,” a dusty streamer first spotted in the mid-infrared by JWST.

SPBench: A Multi-Task Evaluation Benchmark for Exploration Seismic Processing
A public seismic-processing benchmark re-runs 24 learning methods on shared data and shows that winning on synthetics does not reliably mean winning on field r…

Differential Double Blind Fourier Holography (diff-DBFH)
A two-image tweak to Double Blind Fourier Holography sharpens telescope wavefront estimates using a small pupil-plane poke, without a dedicated interferometer.

Motif-Vocab: StatisticallyCalibrated Transcription-Factor-Identity Tokenization forGenomic Language Models
A DNA tokenizer that emits transcription-factor identity tokens — not just letters or k-mers — helps motif-sensitive genomic models without beating every dense…

Integration of p-type Cr2O3 on Ultra-Wide Bandgap AlGaN PolFETs with 2.5 kV Breakdown Voltage
Room-temperature-sputtered p-type chromium oxide gates on AlGaN polarization transistors deliver more than 2.5 kV breakdown and a very low contact resistance.

Shallow-to-deep velocity model building via diffusion models-Part II: Realistic scenarios
A depth-progressive diffusion model builds seismic velocity models from messy real-world clues and is good enough, the authors say, to start full-waveform inve…

Molecular Beam Epitaxy of AgTaO3
The first single-crystal silver tantalate thin films are grown by ozone molecular-beam epitaxy on strontium titanate, with a catch on the (111) orientation.

Singularities of the cold plasma theory: Modeling challenges for ICRF operation in low-density edge plasma
Cold-plasma theory still predicts needle-sharp radiofrequency fields in low-density tokamak edges, even after collisions — so the usual collisional model is no…
