Economic costs of protecting islands from invasive alien species

Conservation Biology, Volume 37, Issue 2, April 2023., 2023
Abstract Biological invasions represent a key threat to insular systems and have pronounced impacts across environments and economies. The ecological impacts have received substantial focus, but the socioeconomic impacts are poorly synthesized across spatial and temporal scales.

Associations between the Trauma Memory Quality Questionnaire and posttraumatic stress symptoms in youth: A systematic review and meta‐analysis 

Journal of Traumatic Stress, Volume 36, Issue 1, Page 31-43, February 2023., 2023
Abstract Cognitive models of posttraumatic stress disorder (PTSD) propose that trauma memory characteristics are implicated in the etiology of the disorder. Empirical support for cognitive models in youth is necessary to ensure psychological interventions are based on appropriate theory.

Association of skin autofluorescence with low bone density/osteoporosis and osteoporotic fractures in type 2 diabetes mellitus 皮肤自发荧光与2型糖尿病患者低骨密度/骨质疏松及骨质疏松性骨折的关系

Journal of Diabetes, Volume 14, Issue 9, Page 571-585, September 2022., 2022
Highlights The association between skin autofluorescence advanced glycation end products (SAF‐AGEage) and low bone density/osteoporosis or major osteoporotic fractures was noteworthy in patients with type 2 diabetes mellitus (T2DM). SAF‐AGEs were positively associated with the level of serum N‐terminal propeptide of type I procollagen (s‐PINP) and ...

复杂钢管空间节点应力集中系数研究

Jianzhu Gangjiegou Jinzhan, 2021
为了研究复杂钢管空间节点的应力集中系数,采用有限元软件ANSYS建立了复杂钢管空间节点有限元模型。有限元模型考虑了焊缝的影响,将有限元计算结果与试验结果进行比较,二者吻合较好,从而验证了有限元模型的可靠性。对复杂钢管空间节点模型进行了参数分析,研究了各个参数对节点应力集中系数的影响。参数分析结果表明,主管径厚比γ对节点应力集中系数的影响较大;其他参数对节点应力集中系数的影响较小。对252个参数分析模型的结果进行回归分析,建立了节点各部分应力集中系数的拟合公式。拟合公式计算值与有限元计算值吻合较好 ...

钢管混凝土翼缘-波纹腹板曲梁抗剪性能分析

Jianzhu Gangjiegou Jinzhan, 2021
采用数值模拟方法对波纹腹板剪切屈曲破坏的钢管混凝土翼缘曲梁承载力问题进行了研究。运用有限元分析软件,建立跨中集中荷载作用下的矩形钢管混凝土翼缘-波纹腹板曲梁(curved girders with rectangular concrete-filled tubular flange and corrugated web, CG-RCFTF-CW)的有限元模型。利用有限元建模方法分别对平翼缘波纹腹板直梁和钢管混凝土翼缘平腹板曲梁建立了相应的有限元模型 ...

A Meta‐Analytic Review of the Association Between Alienation Appraisals and Posttraumatic Stress Disorder Symptoms in Trauma‐Exposed Adults

Journal of Traumatic Stress, Volume 33, Issue 5, Page 720-730, October 2020., 2020
Abstract Ehlers and Clark's (2000) cognitive model of posttraumatic stress disorder (PTSD) highlights the importance of negative appraisals in maintaining posttraumatic stress. Recent research suggests that alienation appraisals, defined as feeling disconnected from the self and others, mediate the association between traumatic experiences and ...

Understanding conflicting cultural models of outdoor cats to overcome conservation impasse

Conservation Biology, Volume 34, Issue 5, Page 1190-1199, October 2020., 2020
Abstract Many conservation conflicts are scientifically complex yet are rooted in value conflicts, which result in an impasse. Additional biological information alone is insufficient to resolve this type of conflict. Conceptual models that articulate the material aspects of a system are increasingly used to identify areas where parties disagree.

六边形钢管混凝土构件的受扭性能研究

Jianzhu Gangjiegou Jinzhan, 2021
通过有限元分析软件ABAQUS研究了六边形钢管混凝土构件的纯扭力学性能。首先建立了方形和圆形钢管混凝土纯扭构件的有限元模型,并将模拟结果与相应试验结果进行对比,以验证有限元模型的准确性;接着采用验证的有限元模型分析了六边形钢管混凝土纯扭构件的扭矩(T)-剪应变(γ)关系曲线、构件剪应力分布规律和钢管对混凝土的约束力分布规律;最后通过探究典型参数对六边形钢管混凝土构件抗扭性能的影响,给出了六边形钢管混凝土纯扭构件承载力的建议简化计算公式。与有限元模拟结果相比,简化计算公式的结果与其拟合程度较高 ...
