A Consecutive Missing-Data Recovery Method for Bridge Health Monitoring Based on an ICEEMDAN-PE-LSTM-Informer Hybrid Model

Accurately reconstructing consecutive missing measurement segments presents a major challenge in bridge structural health monitoring, due to the inherent complexity and non-stationary nature of the collected signals. To address this, a hybrid data recovery framework is developed...

Experimental Study on the Gas–Solid Flow Mechanism with Variable Particle Property in a Multistage Fluidized Bed Riser

Abstract Variable-diameter CFBs have been receiving increasing attention due to its synergistic regulation of solid holdup, contact efficiency, and residence time. Nevertheless, the influence of particle property on the complex gas–solid hydrodynamics remains poorly understood. T...

Advanced Separators for High‐Safety and High‐Energy‐Density Rechargeable Batteries

ABSTRACT The growing dependence of modern society on batteries places higher demands on safety and energy density. Separators are a key component for electrical insulation and structural stability to ensure battery safety. Their inactive volume, ability to regulate solvated ions...

Prussian blue regulates ion dynamics in perovskite solar cells

Perovskite photovoltaics are limited by structural instabilities initiated during crystallization and amplified under operation. We report that a lattice-matched Prussian blue scaffold directs heterogeneous nucleation to produce highly oriented, strain-relaxed films. Its redox-ac...

Solar‐Driven Photocatalytic H 2 O 2 Production: Mechanistic Foundations, Catalyst Design, Performance Benchmarking, and Sustainable Applications

ABSTRACT Hydrogen peroxide (H 2 O 2 ) is a clean oxidant, disinfectant, and candidate liquid energy carrier, yet its industrial manufacture remains dominated by the energy‐intensive anthraquinone process. Solar photocatalytic H 2 O 2 synthesis offers a decentralized alternative t...

Leaf–Litter–Soil C:N:P Stoichiometry Varies with Stand Age in Three Subtropical Plantation Types

Stoichiometry provides an integrative framework for evaluating nutrient dynamics in plantation ecosystems. However, whether stand-age-related changes in leaf–litter–soil carbon (C), nitrogen (N), and phosphorus (P) stoichiometry are consistent among plantation types remains uncle...

High‐Throughput Dual Resonance and Non‐Resonance Mode Raman‐Activated Cell Sorting With Low‐Volume Harvesting

ABSTRACT Raman‐activated cell sorting (RACS) platforms are limited by inflexibility in tackling different Raman signals and inability to export the sorted cells in a sufficiently low volume for downstream processing. Here, we present a generally applicable RACS platform that tack...

Carbon-Fiber Structural Batteries: From Multifunctional Integration to Retained Reliability

Carbon-fiber structural batteries represent a class of multifunctional energy-storage systems that integrate electrochemical energy storage with mechanical load-bearing capability. Unlike conventional batteries, which are mainly evaluated based on cell-level energy density, struc...

Numerical Investigation of Competitive Methane Transport in Multiborehole Coal Seam Drainage and Its Implications for Borehole Layout Design

Abstract Methane drainage efficiency in coal seams is significantly affected by borehole arrangement, as overlapping pressure sinks in multiborehole systems can redistribute gas migration pathways and reduce the effective performance of individual boreholes. To quantify this inte...

Multi-Horizon Short-Term GPU Utilization Forecasting Based on Deep Sequence Models

Short-term GPU utilization forecasts are useful for scheduling, resource allocation, and capacity planning, but production traces are rarely smooth. They contain spikes, regime changes, idle periods, and incomplete observations. We study this problem on the MIT Supercloud Dataset...

Nanotoxicity of Ultrasmall Silver Nanoclusters to Cyanobacteria

Cyanobacteria are essential primary producers in aquatic ecosystems. Silver nanoclusters (Ag NCs) are emerging ultrasmall nanomaterials with broad applications; however, they inevitably enter aquatic environments. This study investigated the nanotoxicity of Ag NCs on model cyanob...
