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...

Pelvic magnetic stimulation added to pelvic-floor muscle training for female vaginal laxity: a randomized controlled trial

To evaluate the short-term efficacy of pelvic magnetic stimulation combined with pelvic floor rehabilitation training (Intervention) versus isolated pelvic floor muscle training (PFMT) among women diagnosed with vaginal laxity (Population). The Vaginal Laxity Questionnaire (VLQ)...

Dose-Dependent Preservation of Highland Barley Flour Storage Quality by Lycium barbarum Polysaccharide: Evidence from 240-Day Storage Monitoring and Untargeted Lipidomics

Highland barley (hulless barley, Hordeum vulgare L. var. nudum) flour is a nutritionally dense staple of the Qinghai–Tibet Plateau, but its high contents of unsaturated lipids and active endogenous enzymes render it highly susceptible to storage deterioration. Natural polysacchar...

Integrated Transcriptomic and Metabolomic Analyses Reveal Leaf Regulatory Mechanisms Underlying Low-Nitrogen Tolerance in Oat (Avena sativa L.)

Nitrogen deficiency limits oat growth and productivity, but the molecular basis of contrasting low-nitrogen responses among oat germplasms remains poorly understood. This study compared the low-nitrogen-tolerant germplasm Jiayan No.2 with the low-nitrogen-sensitive germplasm ZNY2...

Oxygen Plasma-Activated PES Ultrafiltration Substrates for Constructing High-Performance Mg2+/Li + Separation Nanofiltration Membranes

Abstract Positively charged polyamide (PA) nanofiltration (NF) membranes hold great potential for Mg2+/Li+ separation, but their performance is strongly affected by the surface properties and pore structures of the substrate. In this study, a PES ultrafiltration substrate was pre...

One-Tube Nested MGB Probes Real-Time PCR Assay for Detecting Echinococcus multilocularis Eggs

Echinococcus multilocularis is a zoonotic cestode capable of causing disease in humans and animals. Its eggs are released into the environment via the feces of definitive hosts and are the direct infectious source of human alveolar echinococcosis. Therefore, sensitive and species...

The complete chloroplast genome of Mesosphaerum suaveolens (L.) Kuntze and phylogenetic position in the Lamiaceae family

The complete chloroplast genome of Mesosphaerum suaveolens is 152,555 base pairs long and has a typical quadripartite structure. It contains 132 genes, including 13 cis-splicing genes, 2 trans-splicing genes (rps12), and 8 tRNA genes with introns. A total of 47 simple sequence re...

Response of alpine runoff to the ‘Warming and Wetting’ climate change trend: a Budyko-based attribution analysis in the Daheba Basin

ABSTRACT Understanding runoff responses in al pine basins is essential for water-resource management under climate change. This study assessed runoff changes and their drivers in the Daheba Basin, northeastern Tibetan Plateau, using hydrometeorological and land-surface data for 1...

Uncertainty-aware bilevel energy storage planning for active distribution networks: A fixed-topology DistFlow-based MISOCP framework with voltage-security assessment

Historical renewable-load variability, voltage-security risk, and investment-operation coupling can materially change the assessed value of distribution-level energy storage. This study develops an uncertainty-aware bilevel energy storage system (ESS) planning framework in which...

A novel spatiotemporal multivariate partial grey model for multi-segment traffic flow and its application

Purpose The traffic flow system is a complex dynamic system, and the traffic flow data have complex spatiotemporal characteristics. Therefore, to deeply explore the spatiotemporal characteristics of traffic flow data, a novel spatiotemporal multivariate partial grey prediction mo...

Unveiling potential genetic markers: associations of IGF1R eon 13 and Intronic polymorphisms with growth traits in yak

This study aimed to investigate the associations between single-nucleotide polymorphisms (SNPs) and haplotypes in the exon 13 and the intronic regions of the yak IGF1R gene and growth traits, with the goal of identifying molecular markers related to growth performance. A total of...

Drought Severity Shapes Recovery Trajectories of Root Functions and Rhizosphere Processes in Poa pratensis During a Drought–Rewatering Cycle

Drought–rewatering events are becoming increasingly frequent on the Qinghai–Tibet Plateau, yet how drought severity shapes post-drought recovery of root functions and associated rhizosphere enzyme activities remains unclear. Here, Poa pratensis from Zeku Zequ National Wetland Par...

Improved estimation of lake storage variation via DEM reconstruction integrating elevation and morphological constraints

High-quality Digital Elevation Models (DEMs) are essential for accurately estimating lake storage variations, but the high cost of in-situ measurements limits their large-scale application. Reconstructing DEMs from remote sensing-derived lake contours is a promising low-cost alte...

PPG as a Bridge: Cross-Device Authentication for Smart Wearables with Photoplethysmography

As smart wearable devices become increasingly powerful and pervasive, protecting user privacy on these devices has emerged as a critical challenge. While existing authentication mechanisms are available for interaction-rich devices such as smartwatches, enabling on-device authent...

AuthGlass: Benchmarking Voice Liveness Detection and Authentication on Smart Glasses via Comprehensive Acoustic Features

With the rapid advancement of smart glasses, voice interaction has been widely adopted due to its naturalness and convenience. However, its practical deployment is often undermined by vulnerability to spoofing attacks, while no public dataset currently exists for voice liveness d...

Earinter: A Closed-Loop System for Eating Pace Regulation with Just-in-Time Intervention Using Commodity Earbuds

Rapid eating is common yet difficult to regulate in situ, partly because people seldom notice pace changes and sustained self-monitoring is effortful. We present Earinter, a commodity-earbud-based closed-loop system that integrates in-the-wild sensing, real-time reasoning, and th...

Towards Wearable Opportunistic Crowdsensing for Open-Vocabulary Activity Data Collection Through User-Scheduled Trigger-Action Routines

Collecting richly labeled wearable activity data in everyday settings remains difficult because retrospective annotation is costly and often imprecise. Prior data collection apps rely on a labor-intensive self-reporting strategy and primarily treat participants as crowd labelers....

EaMIC3 inhibits cell apoptosis and facilitates Eimeria acervulina infection through interacting with EpCAM

Coccidiosis, caused by Eimeria acervulina, is a pathogenic protozoan disease, leading to huge economic losses to the global poultry industry. At the early stage of E. acervulina infection, microneme protein 3 (EaMIC3) is involved in the inhibition of infected host cell apoptosis,...
