Synthesizing Empirical Research on Learner Metacognition in Second Language Writing
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite considerable research interest in learner metacognition in second language (L2) writing, there is not yet a review that synthesizes the existing empirical findings and discusses their implications. To fill the void, this systematic review synthesized 39 empirical studies on learner metacognition in L2 writing and examined their salient

Zhendong Ceshi yu Zhenduan为了描述减振器的动态特性，将集总参数模型和神经网络模型进行结合，提出了一种能够精确描述减振器非线性动态特性的集总参数‑神经网络联合模型。首先，在减振器测试台架上对一个减振器的动态特性进行测量，激励工况包括谐波激励和瞬态激励两大类，测试得到减振器的动态力响应；其次，提出了联合模型的集总参数建模方法与参数辨识方法，并使用谐波激励下的测试数据完成了模型参数辨识；然后，利用神经网络模型补偿减振器的力‑速度非线性特征；最后，使用联合模型计算在瞬态激励下减振器的输出力 ...

Basic income trials and the politics of scale: A research agenda
Policy Studies Journal, EarlyView.Abstract The growing popularity of basic income has led to extensive trials of the policy in numerous settings across the world. However, analysis of the politics of basic income, and in particular the political dynamics preceding and resulting from trial programs, lags. In response, we propose a research agenda that uses political scale to investigate

ABCA12 Frameshift Deletion in Domestic Cats With Ichthyosis Fetalis
Veterinary Dermatology, EarlyView.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.

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...
