EGOSTREAM: A Diagnostic Benchmark Exposing Critical Gaps in Streaming Episodic Memory for Egocentric AI Agents

EGOSTREAM is a new diagnostic benchmark targeting a largely unaddressed gap in streaming video understanding: how well multimodal LLMs retain and recall episodic memory over time. It introduces the Answer Validity Window (AVW) construct to separate genuine model forgetting from natural world-state changes, enabling controlled recall testing across timescales. Evaluated across multiple memory-management strategies (sliding windows, attention sinks, KV-cache pruning/merging/offloading) on a Qwen3-VL backbone, the benchmark reveals that aggregate accuracy metrics mask radically different underlying memory profiles — and that all current mechanisms fail to meet real-time processing requirements, with top methods capping at ~45% accuracy.

EGOSTREAM: A Benchmark Exposing Critical Gaps in Streaming Episodic Memory for Egocentric Vision Models

EGOSTREAM is a diagnostic benchmark targeting streaming episodic memory in egocentric vision, addressing the lack of fine-grained temporal evaluation tools in existing video benchmarks. It introduces 2,250 curated questions across seven cognitive dimensions and the Answer Validity Window (AVW) concept, expanding to 8,528 recall-conditioned evaluations spanning instant to ultra-long-term recall. Baseline experiments using a unified Qwen3-VL backbone reveal that aggregate accuracy metrics obscure divergent memory profiles across mechanisms, and that all tested state-of-the-art methods fail to operate in real-time while topping out at ~45% accuracy — exposing fundamental architectural limitations.

Data-Free Gradient Inversion MIA Breaches FL Privacy in Hardware Assurance Using SCLL Priors

Researchers present a data-free membership inference attack (MIA) on federated learning (FL) for image segmentation models in hardware assurance, using standard cell library layouts (SCLLs) as priors to guide gradient inversion and reconstruct client images from intercepted model updates. The attack enables inference of sensitive hardware IP, such as distinguishing circuit layers (metal vs. diffusion) and technology nodes (32nm vs. 90nm), by analyzing reconstruction fidelity. A novel conditional loss term enhances attack efficacy on structurally complex data, demonstrating severe privacy leakage without auxiliary datasets.

Standard Cell Library Enables Privacy Breach in Federated Learning for Hardware Assurance

DECIFR exploits domain knowledge from standard cell library layouts to perform a two-stage membership inference attack on federated learning in hardware assurance. It uses guided gradient inversion to reconstruct client training images from model updates without auxiliary data, with reconstruction fidelity indicating membership status. This reveals that standard FL protocols fail against adversaries with domain-specific prior knowledge, necessitating robust defenses.

Federated Learning Boosts Hardware Assurance but Exposes IPs to Gradient Inversion

Federated Learning (FL) enables collaborative DL model training for automated reverse engineering in hardware assurance without sharing raw data, outperforming single-client centralized learning in SEM image segmentation tasks. Performance improves with more clients due to aggregated data contributions. However, FL remains vulnerable to gradient inversion attacks, allowing recovery of sensitive SEM images and proprietary IPs.

Mimetic Deception for IP Camouflaging Thwarts Reverse Engineering

This paper introduces "mimetic deception" as a novel anti-reverse engineering technique for semiconductor intellectual property (IP). By making a functional IP (F) appear structurally and visually as a different IP (A), this method aims to fool reverse engineering toolchains. This approach specifically addresses vulnerabilities in traditional IC camouflaging methods by obfuscating both localized gate functionality and system-level structural analysis, thereby achieving a multi-layered defense.

High-Fidelity 3D Vehicle Reconstruction in Dynamic Dealership Environments

This paper introduces a novel pipeline for high-fidelity 3D reconstruction of vehicle exteriors within challenging, dynamic dealership drive-throughs. The method addresses issues like cluttered static backgrounds, wide-angle lens distortion, specular paint, and non-rigid wheel rotations by integrating instance segmentation, motion-gating, robust learned matchers, rig-aware SfM, and a distortion-aware 3D Gaussian Splatting framework. This approach achieves inspection-grade 3D models without requiring studio infrastructure, significantly improving reconstruction quality compared to standard methods.

Replication-Driven Nucleoid Clustering Orchestrates Bacterial Chromosome Segregation

Bacterial chromosome organization and segregation, despite the absence of a spindle apparatus, are driven by the interplay of DNA replication and nucleoid-associated protein (NAP) interactions. A 3D polymer model simulating DNA synthesis reveals that NAP-mediated clustering generates density fluctuations, leading to stepwise nucleoid expansion and chromosome segregation. This mechanism operates within an optimal range of NAP interaction strengths, highlighting replication as a non-equilibrium process that drives genome mechanics and dynamics.

Electron-Ion Collider: Advancing Precision QCD and Nuclear Structure

The Electron-Ion Collider (EIC) program, a collaborative effort of theorists, experimentalists, and computer scientists, aims to significantly advance precision Quantum Chromodynamics (QCD) and nuclear structure understanding. Key research areas include higher-order perturbative-QCD calculations, nuclear tomography, parton distribution function comparisons, and the identification of saturated gluon signatures. The program also assesses the role of AI in EIC studies and detector development, highlighting a multifaceted approach to fundamental physics.

Shock-Induced Isostructural Spin Transition in FeO

High-pressure shock compression experiments on FeO reveal an anomalous 7-10% volume collapse at approximately 60 GPa without a structural transition. This volume collapse is driven by an isostructural high-spin to low-spin metallic transition, directly evidenced by x-ray emission spectroscopy at 180 GPa. These findings diverge from static compression data and impact our understanding of FeO behavior under extreme conditions.
