Relationship Between Group Cohesiveness and Athletic Results--Reasons for Inconsistence of Research Results [PDF]
对体育运动中群体凝聚力的定义及其测量方法进行了概括,并对凝聚力与运动成绩之间的相关研究进行了分析,结果表明,二者之间的关系是复杂的.其中大多数研究表明凝聚力与运动成绩呈正相关,少部分研究表明两者之间没有关系或是负相关.研究认为,导致研究不一致的原因主要与凝聚力的测量方式、任务方式、群体的目标设置有关.另外,在凝聚力与运动成绩关系的研究中还应考虑绩效测量的选择问题.The definition of group cohesiveness in physical education and sport ...

Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Multimodal Data‐Driven Microstructure Characterization
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Effect of Lentinula edodes Stem Nano Dietary Fiber on Low-fat Emulsified Sausage Quality
Lentinula edodes stipes, a byproduct of shiitake mushroom processing, was used as raw materials to prepare nano dietary fiber. After dietary fiber purification, three methods—cellulase hydrolysis, ultrasonic cell disruption, and their combination were ...

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation
