New Directions for Child and Adolescent Development, Volume 2026, Issue 1, 2026.Background Working memory updating is crucial in bilingual children′s second language (L2) reading comprehension. A robust updating ability is a cognitive key for children to successfully master L2 reading comprehension. Objective This study is aimed at investigating the effect of updating ability on the L2 Chinese reading comprehension among Uyghur ...

Wildlife Letters, Volume 3, Issue 4, Page 173-193, December 2025.Spectacled flying‐fox Pteropus conspicillatus populations have declined so seriously over two decades that they are now endangered. Inaction has allowed threats to increase. Extreme heat events are now a lethal reality, habitat loss continues almost unabated, and pressure to disperse roosts is ever‐present. Obtaining resources and taking action to help

Beyond Motivation: Modeling the Predictive Role of L2 Pride in Informal Digital Learning of English
International Journal of Applied Linguistics, Volume 35, Issue 4, Page 1938-1952, November 2025.ABSTRACT This study investigates the role of second language (L2) pride—an understudied affective factor—in shaping learners’ language learning motivation and involvement with informal digital learning of English (IDLE). Drawing on questionnaire data from 1388 Chinese university EFL students, the study employs structural equation modeling to examine ...

四川大学学报. 自然科学版, 2006 利用壳层模型分子动力学方法,研究了高温高压条件下FeO的熔化温度,同时还计算了温度在300K及压强上升到140 GPa时FeO的状态方程.作者在研究中,考虑了分子动力学模拟熔化存在的过热现象,通过晶体的现代熔化理论,对FeO的分子动力学模拟熔化温度进行了修正,获得了高温高压下FeO正确的熔化温度.因此,为常压下利用壳层模型分子动力学研究物质熔化提供了一种较好的方法,该方法亦可进一步推广应用到其它物质的高压熔化研究工作.
