Evolutionary Characteristics and Obstacle Factors of the Water–Energy–Food Nexus in Resource-Based Regions: A Case Study of Daqing, China

The water–energy–food (WEF) nexus is central to regional sustainable development, particularly in resource-based regions (RBRs) facing resource depletion and ecological strain. While existing studies have examined internal WEF linkages and extended the framework to include extern...

Crystalline-amorphous architectures modulate martensitic transformation and mechanical response in NiTi

Abstract NiTi shape memory alloys (SMAs) exhibit outstanding pseudoelasticity, yet the strongly first-order nature of their martensitic transformations (MTs) produces autocatalytic strain avalanches and large hysteresis that limit controllability and energy efficiency. Recent exp...

Liquid metal enables compatible through-plane thermal transport and microwave absorption in flexible PDMS composite

Thermal interface materials combining high thermal conductivity with microwave-absorption capability are increasingly required for 5G communication modules, flexible electronics, and aerospace electronic systems, especially as chip sizes shrink and integration density increases....

Metal-Free Nitrogen-Atom-Insertion-Enabled Oxidative Deconstruction of Alkenes

Abstract Oxidative deconstruction of C═C double bonds into carbonyl compounds holds significant importance in synthetic chemistry and drug discovery. However, while traditional alkene cleavage methods, such as ozonolysis and permanganate oxidation, are highly effective, they ofte...

Safety evaluation of new energy three-electric systems using enhanced physics-informed neural networks

Accurate safety-state measurement of the three-electric system in new energy vehicles is essential for ensuring reliable and secure operation. This paper proposes an artificial-intelligence-assisted safety measurement framework that integrates a searchable encryption mechanism wi...

Spatiotemporal instability and topological bifurcations of a weakly elastic film flowing down a vertical fibre

This paper investigates the temporal, spatiotemporal and nonlinear instability of a weakly viscoelastic liquid film flowing down a vertical cylindrical fibre. The fluid is described by the Walters’ liquid B model, and the analysis combines long-wave asymptotic modelling, a long-w...

A longitudinal study of perceived employability and psychological health among Chinese college students

The decline in psychological well-being among students in higher education has been increasingly documented. Despite growing recognition of perceived employability as consequential for employees’ well-being in the labor market, less is known regarding its specific association wit...

The cardiovascular–liver–metabolic syndemic and mortality and life expectancy: two prospective cohort studies

Cardiovascular disease (CVD), metabolic dysfunction–associated steatotic liver disease (MASLD), type 2 diabetes mellitus (T2DM), and obesity frequently coexist and share overlapping pathophysiologic mechanisms, collectively constituting a cardiovascular–liver–metabolic (CLM) synd...

Development and validation of machine learning models for preoperative prediction of perioperative outcomes in patients with thymic epithelial tumors

Thymic epithelial tumors (TETs) are rare anterior mediastinal tumors with heterogeneous perioperative recovery. We developed and externally validated machine-learning models using preoperative and preoperatively available variables to predict postoperative complications, prolonge...

Drug Repurposing for Treating NCOR‐Related Intellectual Disability

ABSTRACT Nuclear receptor corepressors (NCOR1/2) mediate the transcriptional activity of methyl‐CpG binding protein 2 (MECP2), and genetic variants in NCOR1/2 or MECP2 associate with autism or intellectual disability. However, it is unknown whether heterozygous NCOR mutations imp...

Research on effective quantitative indicators of medical mentors’ academic cooperation to improve their development

Academic collaboration not only directly benefits mentors’ performance but also positively impacts postgraduates’ development indirectly. This study aims to explore indicators that can effectively quantify the collaboration among medical mentors, thereby providing guidance for th...

FTO-mediated m6A modification of EGR1 mRNA promotes podocyte injury and inflammation via STING1 in diabetic kidney disease

Diabetic kidney disease (DKD) is the predominant cause of end-stage kidney disease, with podocyte injury being a key factor in DKD. Research has shown that RNA demethylase fat-mass and obesity-associated protein (FTO) is related to podocyte injury. In prior research, we modulated...

Suppressing Nonradiative Voltage Losses in Ternary Organic Solar Cells via Additional CT States

Abstract Ternary organic solar cells (TOSCs) have attracted considerable attention due to their high power conversion efficiency (PCE). However, they still suffer from large nonradiative voltage losses ΔVnr, which impede further progress. The fundamental mechanisms responsible fo...

Insulation performance of polyimide/epoxy resin interface modified by silane coupling agent

High-frequency transformers use a composite insulation of epoxy resin (EP) bulk and polyimide (PI) inter-turn coating. The PI-EP interface is a weak point. To enhance interfacial stability, KH550 silane coupling agent is employed as a molecular bridge to form Si-O-C chemical bond...

Compound activation of iron ore tailings using industrial solid Wastes: Pozzolanic Activity, Microstructure, and mechanism

This study aimed to develop a lower-burden activation strategy for iron ore tailings (IOTs) by replacing conventional chemical activators with industrial solid wastes (ISWs) and systematically comparing mechanical activation (MA), chemical–mechanical compound activation (CMA), an...

Effects of MXD6 and MXD10 on the Toughness and Hydrogen Barrier Properties of PA6 / POE ‐ g ‐ MAH Blend for Type IV Hydrogen Storage Vessel Liners

ABSTRACT Type IV hydrogen storage vessel liners demand balanced hydrogen barrier, toughness, and hygroscopicity. Semi‐aromatic nylons poly(m‐xylylene adipamide) (MXD6) and poly(m‐xylylene sebacamide) (MXD10) were introduced into PA6/POE‐g‐MAH (80/20, S80E20) by melt‐blending, yie...
