Influence of Secondary Patterning on the Crystalline Quality of Epitaxial GaN Films

Abstract Molecular dynamics simulations were employed to investigate the effects of planar, single-patterned, and secondary-patterned epitaxy on the crystalline quality of GaN thin films. Secondary-patterned epitaxy significantly improves atomic ordering, promotes the formation o...

Achieving High Spatial Resolution Transmission Electron Microscopy Studies in Closed Liquid Cells

Liquid cell transmission electron microscopy (LCTEM) is a rising technique for probing dynamic processes and structural transformations in liquid environments at the nanoscale. However, its broader application is largely constrained by limited spatial resolution, which arises fro...

Mechanistic investigation of the bond-slip behavior of brick-mortar interfaces: From mortar decay to interfacial deterioration under sulfate attack

The bond-slip behavior at the brick-mortar interface plays a pivotal role in the long-term structural integrity of ancient masonry pagodas. Sticky rice paper pulp mortar (SRPPM), a key traditional material, is susceptible to environmental erosion. However, the quantitative link b...

Magnetic properties of ultrafine M-type hexaferrite nanoparticles with tunable sizes prepared by glass-ceramic method

Ultrafine M-type hexaferrite Ba 1- x Sr x Fe₁₂O₁₉ nanoparticles ( x = 0–0.8) were synthesized via a glass-ceramic route where the grain size was controlled by controlling the BaO/SrO ratio in precursor glasses. Sr 2+ substitution induces lattice contraction and reduces the averag...

Interlayer‐Confined LiNO3 Reservoir Enables the Formation of a Li‐Containing Hybrid SEI for Robust Sodium Metal Anodes

ABSTRACT Sodium metal batteries hold great promise for energy storage applications, but are constrained by limited charge transfer kinetics and unstable solid electrolyte interphases (SEI). Here, we construct a montmorillonite‐based sustained‐release separator by confining within...

Finite-time H ∞ control for singularly perturbed systems subject to finite-frequency specification

This paper investigates the design of a parameter-independent finite-time H∞ controller for singularly perturbed systems to address numerical ill-conditioning and enhance robustness under finite-frequency specifications. By integrating the descriptor-system approach with the gene...

Epitope and immunological basis for superior immunogenicity of henipavirus glycoprotein HeV.G over NiV.G in mRNA vaccines

Nipah (NiV) and Hendra (HeV) viruses are highly lethal zoonotic Henipaviruses with pandemic potential, for which no licensed vaccines exist. The surface glycoprotein (G) is the primary target of neutralizing antibodies, yet a systematic comparison of the immunogenicity of NiV.G a...

Oscillation-Stability-Constrained Coordinated Optimal Operation of Grid-Forming Energy Storage for Dynamic Support

The high penetration of grid-following (GFL) renewable energy integrated into weak grids may induce small-signal synchronous oscillations due to the coupling between phase-locked loop (PLL) dynamics and network impedance, thereby limiting renewable energy accommodation and the fl...

Multi‐Scenario Adaptive High‐Fidelity Self‐Healing Elastomer Based on Poly(Ionic Liquid) Containing Polyurethane for Temperature‐Pressure Sensing and Human‐Machine Interaction

ABSTRACT Skin‐friendly ionogels with multi‐scenario adaptive, high‐fidelity, and self‐healing performances were critical building units in wearable signal transmission devices. Traditional ionogels doped with small‐molecule ionic liquids (SMILAs) into polymers yielding weak inter...

Multi-scale Coarse-to-fine Alignment Network for weakly aligned Red–Green–Blue and Thermal salient object detection

Red–Green–Blue and Thermal (RGBT) salient object detection (SOD) aims to detect common conspicuous regions from the visible light and thermal infrared image pair. Due to the different imaging mechanisms of visible light and thermal images, they are usually weakly aligned. Most ex...

Design and analysis of single-layer f-θ metalens enabling wide-field-of-view, low-distortion scanning

F-θ scanning lenses represent a critical component in laser systems for high-end intelligent manufacturing and optoelectronic applications, as they directly govern the system’s positioning accuracy, imaging resolution, and processing quality. In this work, we propose an ultra-thi...

Global maize yield-loss risk under atmospheric–soil moisture compound drought: Roles of phenology and cropping systems

Global maize production is increasingly threatened by drought, yet most assessments rely on single indicators and inadequately account for phenological-stage and cropping-system differences. Here we develop a copula-based Climate-Land Drought Index (CLDI) that integrates the Stan...

Value-at-Risk- and Expectile-Based Systemic Risk Measures and Second-Order Asymptotics: With Applications to Diversification

Abstract. Systemic risk measures play a crucial role in analyzing individual losses conditional on extreme system-wide disasters. In this paper, we provide a unified asymptotic treatment for systemic risk measures. First, we classify them into two families of Value-at-Risk- (VaR-...

Ni─Nb Synergistic Regulation in RuO 2 Nanocrystals Enables Efficient and Stable Acidic Water Oxidation

The activity‐stability trade‐off of RuO 2 ‐based catalysts in the acidic oxygen evolution reaction (OER) remains a major bottleneck for proton exchange membrane water electrolysis (PEMWE). Herein, a synergistic bimetallic codoping strategy was proposed to harness the complementar...

Controlling the Latent Diffusion Model for Generative Image Shadow Removal via Residual Generation

Large-scale generative models have achieved remarkable advancements in various visual tasks, yet their application to shadow removal in images remains challenging. These models often generate diverse, realistic details without adequate focus on fidelity, failing to meet the cruci...

LayerToFair: An Efficient Post-processing Framework for Layer-aware Fairness Repair of Deep Neural Networks

DNNs are increasingly deployed in high-stakes information systems, where fairness is a critical requirement. Existing post-processing methods can repair unfairness without retraining or accessing original data, but they often treat all layers indiscriminately, resulting in high c...

Accelerating Regular Expression Matching over Compressed Data via Decoupled Speculative Execution on FPGA

The common practice of compressing network traffic to enhance transmission efficiency poses a significant challenge to achieving high-speed regular expression matching. Since matching compression data relies on prior decompressed data and earlier matching outcomes, the convention...
