Land Degradation Pathways of Open‐Pit and Underground Mining in Karst Regions: A Spatial Indicator Assessment

ABSTRACT Mining in the karst regions of southwest China threatens ecosystem stability and accelerates land degradation. Regional evaluation rarely distinguishes between degradation pathways in open‐pit and underground operations, due to spatial heterogeneity and geomorphological...

RetFL: a privacy-preserving and traceable framework for robust federated learning

Federated learning (FL) enables multiple clients to jointly train a model without sharing raw data. Decentralized federated learning (DFL) further removes the need for a trusted central coordinator in the aggregation process. However, in decentralized settings, model aggregation...

A Simple Mg(SO3CF3)2-Based Electrolyte with Additive of 2-Methoxyethylamine for Performance Enhancement in Rechargeable Magnesium–Sulfur Batteries

Abstract The exploration of low-cost, environment-friendly and high-performance electrolytes play a pivotal role in the commercial application process of the rechargeable magnesium batteries (RMBs). Here, we successfully prepared a simple Mg(CF3SO3)2-based electrolyte for RMBs th...

A novel cylindrical lithium-ion battery thermal management system based on PCM and liquid cooling coupling

To address the risks of thermal runaway and temperature non-uniformity in cylindrical lithium-ion batteries under high-rate discharge conditions, a novel thermal management system integrating a net-type liquid cooling channel with a square-cavity-encapsulated phase change materia...

Rheological Response, Strength Development and Conditional Age-Progressive Strength Updating of Cement Kiln Dust-Modified Cemented Tailings Backfill

Cement kiln dust (CKD) can partially replace Portland cement in cemented tailings backfill, but its application must satisfy both pipeline transportability and mechanical strength requirements. This study aims to evaluate the rheological and mechanical evolution of a low-carbon C...

Predicting faculty work engagement during China's vocational higher education reform: role stressors and collegial support as a mediating mechanism

Purpose This study examines how role stressors and collegial support influence faculty work engagement in Chinese vocational universities. It positions vocational universities as skills-oriented higher education institutions where academic work is shaped by teaching, reform, admi...

Effect of mesh-belt motor frequency on heat- transfer boundary conditions and quenching distortion of bearing rings

Quenching distortion of bearing rings seriously affects their dimensional accuracy and service performance in industrial production. To address this issue, this study proposes a distortion control method for bearing rings during quenching in widely used mesh-belt furnaces, focusi...

Promoting Polysulfide Conversion via a Lithium-Ion Reservoir Based on La-Doped MoO3 Nanorods for Li-S Batteries

The practical application of Li-S batteries is seriously plagued by the severe shuttle effect and sluggish conversion kinetics of polysulfides. To circumvent these obstacles, we herein construct La-doped MoO3 nanorods (La-MoO3) as a functional lithium-ion reservoir for sulfur hos...

Early Jurassic Granitoids in the Pairigang Area, Tibet: Implications for the Evolution of the Neo-Tethyan Ocean and the Accretion of Juvenile Crust in the Southeastern Lhasa Block

The Jurassic represents one of the most significant periods within the widespread Mesozoic magmatism of the Lhasa Block; however, its formation age and petrogenesis have led to controversy over the deep genetic mechanisms responsible for magmatism. To address this, we present new...
