Independent Amplitude‐Phase Control in Liquid Crystal for Near‐Field Anti‐Counterfeiting and Far‐Field Holographic Encryption

ABSTRACT Liquid crystal (LC) optical devices provide a promising platform for optical encryption and anti‐counterfeiting applications. However, conventional design paradigms for LC light‐field modulation often involve coupled amplitude and phase responses, limiting design flexibi...

Latency-efficient cloud-edge cultural pattern generation via lossless lightweight condition transmission and bandwidth-adaptive scheduling

Abstract Cloud-edge systems for controllable diffusion generation typically upload the raw reference image, although ControlNet consumes only a sparse structural condition derived from it. We present a cloud-edge framework for directed cultural pattern generation in which the edg...

Nonlinear Responses of Anaerobic Methane Oxidation to Water Table Drawdown in Peatlands

Abstract Anaerobic oxidation of methane (AOM) serves as a key methane (CH4) sink that attenuates methane emissions from peatlands. Climate change has induced widespread water table drawdown in peatlands, but the response of AOM to the water table depth (WTD) and the temperature s...

A Dual-Physics-Informed Neural Network with Incremental Learning for Corrosion Fatigue Crack Growth Prediction in Aluminum Alloys

Aluminum alloys used in aircraft structures are susceptible to corrosion fatigue cracking under combined aggressive environments and cyclic loading, threatening structural integrity. Pure data-driven models often fail under distribution shifts, while single-physics-informed neura...

HfO2/Y2O3 Bilayer Memristor with Gradual Conductance Modulation for Neuromorphic Computing and Artificial Synapse

Abstract Memristors are promising candidates for neuromorphic computing, but conventional oxide-based memristors suffer abrupt switching and limited synaptic plasticity. This paper reports a W/HfO2/Y2O3/Pt memristor that overcomes limitations through oxygen vacancy gradient and h...

Resolving closely spaced corners using second order Gaussian directional derivatives

Corner detection is a fundamental step in many computer vision tasks, including image matching and 3D reconstruction. However, closely spaced corners are difficult to distinguish because inappropriate smoothing scales may cause the filtered responses of neighboring structures to...

Navigating the diagnostic pitfall of concealed brachial artery disconnection masquerading as simple elbow dislocation

Abstract Background Although neurovascular injuries are known complications of elbow dislocations, they typically present with obvious signs of ischemia. However, it is extremely rare for a complete arterial disconnection to masquerade as a simple dislocation. This specific type...
