International Journal of Applied Linguistics, EarlyView.ABSTRACT Second or foreign language (L2) speaking is a key aspect of L2 competence. While GenAI shows potential to address challenges in L2 speaking development, its role remains insufficiently understood. Self‐Determination Theory (SDT) could explain student language learning engagement. Therefore, this systematic review examines how GenAI affordances

四川大学学报. 自然科学版, 2011 BnGID1基因是本实验室克隆到的AtGID1基因在甘蓝型油菜(Brassica nupus L.)中的同源基因.为了验证该基因在甘蓝型油菜中的功能,我们利用pFGC5941双元载体构建了BnGID1基因的干扰载体并将其转化入甘蓝型油菜野生型"3529"中,得到了BnGID1基因表达被部分抑制的转基因植株.性状观察证明,在BnGID1基因表达被部分抑制后,植株表现出明显的接化特征,高度显著降低,叶片产生皱缩.与水稻,拟南芥中的GID1基因缺失突变体的性状比较证明BnGID1基因具有与OsGID1 ...

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study
International Journal of Applied Linguistics, EarlyView.ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.

水稻中Intronic MicroRNA与其宿主基因功能关系分析
四川大学学报. 自然科学版, 2012 根据已有的水稻基因组注释,对水稻中已知的437个pre-miRNAs的基因组背景加以分析,有98个(～22%)与蛋白编码基因相重叠,其中69个(～16%)位于蛋白编码基因的内含子区域,即intronic microRNAs(in-miRNAs).对这些in-miRNAs的靶基因进行Gene Ontology(GO)富集分析,结果显示in-miRNAs对蛋白质氨基酸磷酸化,DNA整合,蛋白质水解,恒温保持,防御响应等生物学过程中的基因有明显的调控作用.最后 ...

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

血管紧张素转换酶、内皮型一氧化氮合酶和载脂蛋白E基因多态性与冠心病的相关性
Zhongshan Daxue xuebao. Yixue kexue ban, 2006 [目的]研究血管紧张素转换酶（ACE）基因插入/缺失多态性、内皮型一氧化氮合酶（eNOS）基因G894T多态性和载脂蛋白E（ApoE）基因多态性与冠状动脉粥样硬化性心脏病（冠心病）的关系.[方法]应用基因芯片技术分析133例冠心病患者和122例对照者ACE、eNOS和ApoE基因多态性,对比两组基因型及等位基因频率.[结果]冠心病组ACE DD基因型频率比对照组显著升高,28.6% vs 13.1%,P＜0.01,ACE基因多态性与冠心病危险性相关.两组eNOS和ApoE基因型频率差异无统计学意义（P ...
