International Journal of Applied Linguistics, Volume 35, Issue 3, Page 1134-1148, August 2025.ABSTRACT E‐books, powered by multimedia and interactive features, are widely used to support young children's language and literacy development. This study examines the relations of e‐book narration and bilingual parent–child talk to children's learning during shared reading. Data from 121 English learners in China and their parents were analyzed using

Racial and ethnic disparities in obstetric anal sphincter injury: cross‐sectional study in the USA
Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 6, Page 778-789, June 2025.ABSTRACT Objectives Racial disparities in obstetric anal sphincter injury (OASI) are poorly understood; their investigation by parity, obstetric history and mode of delivery may provide insight into which individuals are at the greatest risk for OASI. We aimed to quantify the association of race and ethnicity with OASI, stratified by parity, obstetric ...

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 5, Page 624-632, May 2025.ABSTRACT Objectives Placental insufficiency contributes to many obstetric pathologies, but there is no bedside clinical tool to evaluate placental perfusion. We have developed a method to acquire multiple three‐dimensional (3D) power Doppler (PD) ultrasound (US) volumes of placental vasculature, with infrared camera tracking of the precise spatial ...

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 4, Page 470-477, April 2025.ABSTRACT Objective To evaluate the presence and levels of cytomegalovirus (CMV) cell‐free DNA (cfDNA) fragments in women pregnant with a fetus with symptomatic congenital CMV (cCMV). Methods The study comprised nine women whose fetuses were diagnosed with cCMV between June 2019 and July 2024 at 20 + 4 to 34 + 1 weeks' gestation (n = 8) or neonatally (n

Hair fragility (trichorrhexis nodosa) in alopecic Pomeranian dogs
Veterinary Dermatology, Volume 36, Issue 1, Page 64-73, February 2025.Background – Alopecia associated with hair cycle arrest (HCA, Alopecia X) is well‐recognised in Pomeranian dogs. The authors are unaware of reports of hair fragility in affected dogs. Hypothesis/Objectives – Following the observation of frequent hair shaft abnormalities in alopecic Pomeranians, we hypothesised that hair fragility events would be more ...

Gaoya dianqi, 2014 电缆中间接头复合界面受潮是中压交联电缆的常见缺陷,在运行的过程中会导致界面表面电阻下降,进而产生沿面放电,逐渐降低电缆的绝缘性能,甚至直接导致电缆中间接头绝缘击穿事故,给电缆线路的安全稳定运行带来严重隐患。笔者根据电缆中间接头的结构特征建立了复合界面受潮缺陷的等效电路模型,仿真分析了不同程度受潮缺陷下,注入脉冲信号的时域反射波形图谱及其典型特征。提出了一种采用基于注入脉冲信号时域反射波法检测与定位电缆中间接头复合界面不同程度受潮缺陷的方法,并通过工业应用案例验证了该方法的有效性。

Conservation Biology, Volume 38, Issue 6, December 2024.Abstract Growing human use of the marine environment increases the proximity of humans to marine wildlife and thus likely increases human–wildlife interactions. Such interactions influence perceptions of nature and promote or undermine conservation. Despite their importance, human–wildlife interactions are rarely considered in ecosystem‐based marine ...

Gaoya dianqi, 2018 SF6高压断路器触头间的动态接触电阻是反映SF6高压断路器弧触头烧蚀程度的一个重要参数。研究弧触头动态接触电阻与弧触头的烧蚀程度之间的关系具有重要意义。基于电接触理论,建立了一个弧触头动态接触电阻仿真的理论模型。通过开断过程中的弧触头受力情况分析,得出在八触指自力型弧触头模型中,电流小于2 k A时,可忽略各种电动力的影响,只考虑触指接触压力的影响。在这个假设下,文中首次建立了简化的弧触头动态接触电阻的仿真模型。与大量弧触头模拟烧蚀试验结果对比,文中所提出的弧触头动态接触电阻仿真模型 ...
