Attainment Pairing Effects on Cognitive Conflict in Technology‐enhanced EFL Cooperative Tasks
International Journal of Applied Linguistics, Volume 36, Issue 2, Page 1594-1605, May 2026.ABSTRACT This study examines how attainment pairing (high‐high versus high‐low versus low‐low attainment) impacts English as a Foreign Language (EFL) learner engagement during technology‐enhanced cooperative writing tasks. Seventy‐eight Chinese university learners formed 39 dyads (13 pairs per group) via Tencent Meeting.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The stability of aqueous Zn2+ batteries is severely hindered by parasitic reactions at the Zn anode/electrolyte interface. Herein, itaconic acid (IA) is introduced as an effective electrolyte additive to achieve a highly stable zinc anode. Remarkably, IA concurrently modulates both the zinc anode/electrolyte interfacial structure and the Zn2 ...

基于并行小种群差分进化算法的水火电力系统短期优化调度 [PDF]
, 2018 为解决水火电力系统短期发电优化调度中存在的问题,提出基于MPI平台的并行小种群差分进化算法。该算法将进化种群分为若干个小种群(单个种群规模为3~10个),每个进化种群由不同的CPU进程独立执行差分进化算法,并在种群间引入集合、分散操作以协调各小种群的寻优过程;为降低小种群初始化和进化过程中多样性的损失,引入正交化初始化方法和种群重构技术;最后以典型案例验证了算法的有效性。结果表明,该方法在求解精度、收敛速度和求解耗时上均较有竞争力。国家自然科学基金项目(61403321);;广东省自然科学基金项目 ...
