Incorporating multidimensional behavior into a risk management tool for a critically endangered and migratory species

open access: yesConservation Biology, Volume 37, Issue 5, October 2023., 2023
Abstract Conservation of migratory species exhibiting wide‐ranging and multidimensional behaviors is challenged by management efforts that only utilize horizontal movements or produce static spatial–temporal products. For the deep‐diving, critically endangered eastern Pacific leatherback turtle, tools that predict where turtles have high risks of ...

Psychological First Aid principles within a community‐led arts initiative: lessons from the Blacksmiths' Tree

open access: yesDisasters, Volume 47, Issue 3, Page 806-829, July 2023., 2023
Psychological First Aid (PFA) is widely used in the early phases of disaster recovery, despite limited empirical evidence supporting its application. PFA aims to reduce distress and encourage adaptive coping and is grounded in five principles: the promotion of hope, self‐ and collective efficacy, social connectedness, safety, and calm.

Decision‐support tools for dynamic management

open access: yesConservation Biology, Volume 34, Issue 3, Page 589-599, June 2020., 2020
Abstract Spatial management is a valuable strategy to advance regional goals for nature conservation, economic development, and human health. One challenge of spatial management is navigating the prioritization of multiple features. This challenge becomes more pronounced in dynamic management scenarios, in which boundaries are flexible in space and ...

Interfacial Dipole Engineering With Taurine‐Modified SnO2 Electron Transport Layer for Efficient and Stable Perovskite Solar Cells

open access: yesRare Metals, EarlyView.
ABSTRACT Organic‐inorganic metal halide perovskite solar cells (PSCs) are promising for photovoltaics due to their excellent optoelectronic properties. However, achieving high efficiency and stability remains challenging, mainly due to defects and energy losses at the electron transport layer (ETL)/perovskite interface.

肝硬化门静脉高压无创诊断进展

open access: yesZhongguo shiyan zhenduanxue, 2023
门静脉高压(Portal Hypertension,PH)是各种原因导致的肝内阻力增加和门静脉血流增加的结果。肝硬化是PH最常见的原因,PH也是肝硬化患者失代偿期的主要表现,常导致胃底食管静脉曲张破裂、顽固性腹水、脾功能亢进、肝性脑病等严重并发症的出现,威胁患者生命。因此,及早诊断PH并进行分层评估对患者临床管理,改善预后有重要临床价值[1-4]。目前临床上用肝静脉压力梯度来判定门静脉压力,即经颈静脉置管测定肝静脉楔压与肝静脉自由压的压力差。当HVPG大于5mm Hg时可诊断为PH ...

Electrospun Carbon Nanofiber‐Based Multifunctional Electrocatalysts for Zinc‐Air Batteries and Overall Water Splitting: Fabrication, Progress, and Perspective

open access: yesRare Metals, EarlyView.
ABSTRACT The development of high‐performance and stable electrocatalysts for oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) plays a critical role in advancing clean energy technologies, including metal‐air batteries and hydrogen production through overall water splitting.

Unresolved–Disorganized Attachment is Associated With Smaller Hippocampus and Increased Functional Connectivity Beyond Psychopathology

open access: yesJournal of Traumatic Stress, Volume 32, Issue 5, Page 742-752, October 2019., 2019
Abstract Loss and abuse in children can lead to unresolved–disorganized (UD) attachment. How this condition relates to brain structure and functional connectivity (FC) is unknown. We therefore aimed to investigate gray matter volume (GMV) and resting state functional connectivity (RSFC) correlates of UD attachment in adolescents.

型钢连接装配式剪力墙抗震性能研究

open access: yesJianzhu Gangjiegou Jinzhan, 2023
采用带锚筋的锚板、腹板、端板以及加劲板作为连接件,可实现相邻上下层预制混凝土墙板之间的干式连接。为研究该新型全装配式剪力墙的受力性能和抗震性能,进行了2个剪跨比为1.916的试件和1个相同剪跨比和配筋率的现浇整体墙体的低周往复拟静力试验,分析了该全装配式剪力墙的承载能力、耗能能力、延性、位移角、耗能效率、刚度退化等性能。研究结果表明:现浇整体墙体和全装配式剪力墙的破坏形式均为受弯破坏,全装配式剪力墙的耗能能力、延性、位移角、耗能效率、刚度退化等抗震性能指标与现浇整体墙体基本接近,但承载力有所提高 ...

Dynamic Analysis of Dry-jointed Structure—Case Study on Yingxian Wood Pagoda of China [PDF]

open access: yes, 2017
常见的干架结构包括传统的干砌或弱浆砌砖石结构、中国古建筑木结构等空间多体干连接组合结构体系。该类结构由多个块体构件按照一定规则简支叠置,构件间不采用粘结材料形成拉结,借助自重及摩擦力抵抗侧向力。目前对干架结构的研究较少,且已有的对干架结构的数值模拟研究多基于连续杆系结构思想,与实际差异较大。本文从干架结构的特点出发,采用多体动力学及离散单元法对简单的块体干架结构进行分析,进而对中国古代建造的干架结构的典型——应县木塔进行探索。 运用理论力学方法及UDEC离散元软件建模分析,得出了在平面干连接接触 ...
