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.

神经干细胞的单层培养及分化过程中ＨＥＳ１和ＭＡＳＨ１的表达变化

Zhongshan Daxue xuebao. Yixue kexue ban, 2014
摘 要： 【目的】 建立神经干细胞（ＮＳＣ）体外培养方案，使ＮＳＣ的体外可以得到增殖和分化，并检测ＮＳＣ分化过程中ＨＥＳ１和ＭＡＳＨ１的表达变化。【方法】无菌条件下取ＳＤ大鼠胚胎端脑，无血清悬浮培养，形成Ｐ２代神经球后，将神经球消化成单细胞，分为神经球悬浮培养和单层贴壁培养，并对两种不同培养方式下的ＮＳＣ进行干性鉴定和分化能力鉴定。用不同浓度（２０、４０、８０ μｇ／Ｌ）的脑源性神经生长因子（ＢＤＮＦ）诱导ＮＳＣ分化，选出最合适的浓度。用ＢＤＮＦ最佳诱导浓度诱导ＮＳＣ分化，Ｑ ...

CFTR对前脂肪细胞增殖和分化的影响

Zhongshan Daxue xuebao. Yixue kexue ban, 2019
【目的】探讨囊性纤维化跨膜转导调节因子（CFTR）对内脏脂肪组织前脂肪细胞增殖和分化的调控作用。【方法】分别采用CFTR基因敲除小鼠（CFTRKO）4、8周龄及同周龄野生型对照鼠，分离内脏脂肪组织前脂肪细胞，采用实时荧光定量PCR（RT-qPCR）技术检测增殖分化转录因子表达变化。采用地塞米松-异丁基甲基黄嘌呤-胰岛素（DMI）诱导3T3-L1细胞建立前脂肪细胞分化模型，采用免疫印迹（Western blot）技术检测CFTR及分化因子蛋白表达变化；并进一步转染CFTR沉默及过表达病毒，采用免疫印迹 ...

The Emotional Valence Paradox in Social media: A Computational Linguistic Analysis of How Sentiment, Emotion, and Content Domain Predict Social Comparisons on Rednote

International Journal of Applied Linguistics, EarlyView.
ABSTRACT This computational linguistic study analyzes 8743 Rednote posts to examine how sentiment, emotion, and content domain collectively shape social comparison dynamics on social media. We identify four key findings: (1) an emotional gradient, where upward comparison content exhibits the highest sentiment scores and downward comparison the lowest; (
