Research Progress and Challenges of GaN‐Based Micro‐LEDs in Short‐Reach Optical Interconnects

ABSTRACT With the explosive development of the artificial intelligence industry, data centers are facing unprecedented challenges in interconnect bandwidth. Traditional electrical interconnects are gradually approaching their physical limits in terms of bandwidth and power consum...

Effects of Moisture Content on the Thermal Stability and Combustion Performance of HMX

Abstract 1,3,5,7-Tetranitro-1,3,5,7-tetraazacyclooctane (HMX) is a widely used energetic material with high energy density but limited thermal safety. In this work, we systematically investigate the effects of moisture on the thermal stability and combustion behavior of HMX using...

Kissing Number of Codes: A Survey

The kissing number of a code is the average number of pairs of codewords at minimum distance from each other. It has fundamental applications in determining code performance. Besides, a recent interest has arisen from the field of side-channel analysis of algorithms handling sens...

Balancing Interfacial Adsorption and Ion Migration Through a High‐Entropy‐Engineered Oxide for Durable Zinc Anodes

ABSTRACT Oxide coatings, owing to their electronic insulation and ionic conductivity, are promising artificial interfacial layers for stabilizing Zn anodes. However, conventional single‐phase, multiphase, and low‐entropy oxides remain insufficient to simultaneously address the co...

Heterogeneity in trustworthiness reshapes the spatial evolution of trust

Trust is fundamental to cooperation in social and economic interactions, yet its emergence is difficult to explain when individuals occupy asymmetric roles and differ in trustworthiness. How heterogeneous trustee behaviours interact with their spatial organisation to shape popula...

Intrinsic Large‐Unit‐Cell Systems for Advanced Thermoelectrics and Thermal Management

ABSTRACT The urgent demand for efficient thermoelectric conversion and precise heat management technologies drives the search for materials capable of simultaneously optimizing often‐conflicting electronic and thermal transport properties. Intrinsic large‐unit‐cell (LUC) systems,...

CBAM-YOLOv11 and Geometric Constraint-Enhanced PnP for High-Precision EV Charging Port Pose Estimation

The precise detection and pose estimation of electric vehicle (EV) charging ports in unstructured outdoor environments remain challenging due to small sizes, variable illumination, and stringent tolerance requirements for robotic plug-in operations. To address these issues, this...

Dynamic Sliding Behavior of Sand-Filled Rock Joints Under Impact Loading: Evolution of Particle-Size Effects

Blocky-rock masses are prone to dynamic slip along sand-filled joints under impact disturbance. The constraint normal to the joint and the size of the infill particles jointly influence their stability. To determine how axial load and particle-size affect dynamic slip, this study...

Motivating executives for the long run: executive compensation stickiness, long-term focus and the radicalness of corporate innovation

Purpose Radical innovation is crucial for the long-term survival of firms, yet it remains challenging to achieve for most firms. To validate the theoretical rationale of executive compensation stickiness and link managerial cognition to corporate innovation, this study draws on t...

Leveraging human reading behavior for keyphrase extraction: a webcam-based eye-tracking corpus

Purpose Keyphrases are not only statistically or semantically important textual units but also words or phrases that are more likely to attract readers' attention during comprehension. However, existing keyphrase extraction (KPE) studies have mainly focused on improving models' r...

CDSB: accelerating connectomics workflow via Content-Decoupled Schrödinger Bridge

Abstract Background Large-scale connectomics requires the nanometer-scale resolution of electron microscopy to resolve ultrastructural details, but its acquisition is time- and labor-intensive. In contrast, high-throughput light microscopy offers high throughput but lacks the spa...

Thermal cycling–induced nitriding increases energy-storage density in titanate ferroelectric films

Enhancing dielectric energy-storage density ( U e ) requires maximizing the difference between maximum and remanent polarizations (Δ P ). Improving Δ P remains fundamentally challenging, as existing strategies rarely achieve simultaneous high maximum polarization and low remanent...
