The influence of self-supporting personality on social anxiety in college students: the serial-mediating roles of attention bias and social problem-solving orientation

Social anxiety is highly prevalent among college students and is associated with impaired academic functioning and long-term social maladjustment. Although prior research has documented the adaptive value of self-supporting personality, the specific cognitive-behavioral mechanism...

Research progress on multi-mechanism analysis and protection strategies of ovarian aging and fertility decline

Age-related fertility decline is an increasingly important challenge in reproductive medicine, driven largely by progressive ovarian aging. The aging ovary undergoes functional deterioration characterized by reduced ovarian reserve and declining oocyte quality, ultimately limitin...

Physics‐Informed Neural Networks for Flexoelectric Boundary Value Problems: A Reformulated Architecture for High‐ and Mixed‐Order Electromechanically Coupled Systems

ABSTRACT Flexoelectricity denotes a universal electromechanical coupling in dielectric materials, whereby strain gradients break local inversion symmetry and induce electric polarization. The resulting boundary value problem (BVP) is governed by a coupled multi‐physics system of...

Tranexamic acid in primary total knee arthroplasty: a systematic review and meta-analysis of blood loss, transfusion, and deep vein thrombosis

Tranexamic acid (TXA) has been widely used in primary total knee arthroplasty (TKA) to reduce perioperative blood loss, but the pooled evidence regarding blood loss, transfusion, and deep vein thrombosis (DVT) remains to be further clarified. The purpose of this meta-analysis was...

Switchable 2 e − /4 e − ORR Pathway Directed by Spin‐State Engineering for High‐Rate H 2 O 2 Production

ABSTRACT Precise control of the 2 e − /4 e − oxygen reduction reaction (ORR) pathway is essential for directing H 2 O 2 production toward high efficiency and scalability. However, rational regulation of the active site's electronic spin‐states to dictate selectivity remains a fun...
