Zhejiang Daxue xuebao. Lixue ban, 2018 采用密度泛函理论的B3LYP方法、微扰理论的MP2方法和自洽反应场(SCRF)理论的smd模型方法，研究了组氨酸分子3种最稳定构型的手性转变机理及水溶剂化效应.发现标题反应有a、b、c 3条通道，对于构型1和2,a是手性碳上的质子先以氨基为桥迁移，b是羟基异构后手性碳上的质子再以氨基为桥迁移，c是以羧基和氨基联合作桥实现质子迁移.对于构型3，a是质子只以氨基为桥迁移，b是质子顺次以羰基与氨基为桥迁移，c是质子顺次以羧基和氨基为桥迁移.计算表明：构型1和2的主反应通道都是b，决速步自由能垒分别为250 ...

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, EarlyView.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

International Journal of Applied Linguistics, EarlyView.ABSTRACT Research on English‐Medium‐Instruction (EMI) highlights inadequate support for students transitioning from L1‐medium‐instruction to EMI. To date, little research has focused on how L2 students’ adaptation to an EMI environment influences their L2 learning motivation (LLM).

International Journal of Applied Linguistics, EarlyView.ABSTRACT Although the use of AI technologies (e.g., chatbots and automated writing evaluations (AWE)) has gained considerable attention in language learning fields in recent years, how AI technologies have been designed and implemented in language learning education, as well as their effectiveness, is understudied.

Emotion and the Advocacy Coalition Framework: An Affective Dynamics Perspective
Policy Studies Journal, EarlyView.ABSTRACT Despite extensive evidence that emotion and cognition are deeply intertwined, the Advocacy Coalition Framework (ACF) lacks an analytically independent emotional mechanism in its causal architecture—an omission that may be particularly consequential in policy subsystems structured around morally charged, identity‐laden policy disputes.

ABCA12 Frameshift Deletion in Domestic Cats With Ichthyosis Fetalis
Veterinary Dermatology, Volume 37, Issue 3, Page 365-374, June 2026.ABSTRACT Background Ichthyosis fetalis (IF), also known as harlequin ichthyosis, is a rare and often fatal autosomal recessive congenital skin disorder. It is characterized by thickened, hard skin plaques and deep skin fissures that limit mobility and cause malformations of the eyes, lips and ears.

Zhongguo shiyan zhenduanxue, 2014 直结肠癌是世界第二大癌症,致死率也位居第二位。临床分期往往决定了直结肠癌患者的预后,早期阶段确诊的患者往往预后良好[1]。电子顺磁共振谱仪（EPR）可以测定血浆蛋白的功能特性,以HSA为例,采用具有稳定自由基结构（如氮氧自由基,doxyl）的长链脂肪酸作为人工引入的自由基,然后与血清白蛋白结合 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT With the growing severity of volatile organic compounds (VOCs) pollution, metal‐organic frameworks (MOFs)‐derived materials offer a promising solution through efficient photothermal catalysis. In this paper, M‐MnOx (M = Cu, Ni, Co, Fe) catalysts derived from manganese‐based MOFs were successfully prepared by the sacrificial template method and
