Analysis on the damping effect of low yield point steel shear plate in frame structure [PDF]

, 2017
地震作为一种多发的自然灾害，是人类安居乐业的重大隐患，提升建筑物的抗震性能迫在眉睫。早期模式的建筑物依靠结构自身抵御外界荷载，难免造成主体破损，而添加了各类耗能装置的结构，则可以依靠耗能件有效吸收能量，减小主体结构的破损。 低屈服点钢剪切板作为一种新型材料的耗能件，具备良好的耗能性能，探讨将其应用于工程结构的抗震加固和设计有着重要的意义，笔者为此开展了低屈服点钢剪切板耗能件在框架结构中减震效果分析，具体工作如下： （1）介绍低屈服点钢剪切板耗能件的力学原理，探讨加入剪切板耗能件后结构的抗震分析方法 ...

Validating the parental reflective functioning questionnaire ‐ infant version using a rasch model

Infant Mental Health Journal: Infancy and Early Childhood, Volume 46, Issue 4, Page 445-458, July 2025.
Abstract Parental reflective functioning is the parent's ability to reflect on the psychological processes in their child and in themselves as a parent. Recently, an infant version of the Parental Reflective Functioning Questionnaire, PRFQ‐I, has been developed and validated using confirmatory factor analyses.

Radiological findings in the proximal sesamoid bones of yearling and 2‐year‐old Thoroughbred sales horses: Prevalence, progression and associations with racing performance

Equine Veterinary Journal, Volume 57, Issue 1, Page 87-100, January 2025.
Abstract Background Radiological findings in the proximal sesamoid bones (sesamoids) are a persistent source of controversy at Thoroughbred sales, due to inconsistent classification and conflicting assignment of potential clinical importance. Objectives To define the prevalence of sesamoid findings on sales repository radiographs in yearling and 2‐year‐

The effect of sedentary on surface electromyographic activities of lumbar muscles(久坐对脊椎肌肉sEMG信号的影响)

Zhejiang Daxue xuebao. Lixue ban, 2016
采集18名女性受试者在不同久坐时间下，颈夹肌和竖脊肌在最大用力收缩(MVC)过程中的表面肌电(surface electromyography, sEMG)信号，分别考察其初始1. 5 s的线性时频指标AEMG、MPF、非线性分析指标%DET的差异，以及全程MVC过程中MPF的变化趋势，以探讨久坐对脊椎肌肉活动水平和功能状态的影响.发现：在久坐前、久坐1.5 h、久坐3 h之后3种状态下，颈夹肌和竖脊肌在MVC的前1.5 s信号中，其时频信号AE-MG、MPF及非线性信号％DET均无明显变化；在1 ...

Adverse perinatal outcomes are strongly associated with degree of abnormality in uterine artery Doppler pulsatility index

Ultrasound in Obstetrics &Gynecology, Volume 64, Issue 4, Page 504-512, October 2024.
ABSTRACT Objective To investigate the association between varying degrees of abnormality in the Doppler uterine artery pulsatility index (UtA‐PI) and adverse perinatal outcome. Methods This was a prospective study of women with a singleton, non‐anomalous pregnancy in whom UtA‐PI was measured universally in midpregnancy and who gave birth in Oxford ...

Harnessing large language models for coding, teaching and inclusion to empower research in ecology and evolution

Methods in Ecology and Evolution, Volume 15, Issue 10, Page 1757-1763, October 2024.
Abstract Large language models (LLMs) are a type of artificial intelligence (AI) that can perform various natural language processing tasks. The adoption of LLMs has become increasingly prominent in scientific writing and analyses because of the availability of free applications such as ChatGPT. This increased use of LLMs not only raises concerns about

基于时域有限元法的电缆终端电场分析

Gaoya dianqi, 2010
基于后退欧拉法和变分原理推导了非线性的时域有限元电场计算方程。利用时域有限元方法分析了含不同应力控制管时的电缆终端电场分布。分析结果表明,采用由电容性和非线性电阻性材料复合绝缘结构的应力控制管时,电缆终端的电场分布最为均匀。

Use of consumer insights to inform behavior change interventions aimed at illegal pet turtle trade in China

Conservation Biology, Volume 38, Issue 5, October 2024.
Abstract Illegal poaching and overexploitation for the international pet trade are among the greatest threats to freshwater turtles in Southeast Asia. Expanding consumer research in China is crucial to filling knowledge gaps about the scale and structure of illegal trade and developing audience‐targeted and relevant interventions that may reduce demand

Insights from social‐ecological systems thinking for understanding and preventing famine

Disasters, Volume 48, Issue 3, July 2024.
The risk of famine is rising in many countries today. Bold changes to famine information and response systems are urgently needed to improve capacities to prevent famine. To this end, the paper identifies six insights from social‐ecological systems (SES) thinking for understanding and preventing famine.
