Comparative analysis of 2‐year outcomes in GRIT and TRUFFLE trials
ABSTRACT Objective To explore the effect on perinatal outcome of different fetal monitoring strategies for early‐onset fetal growth restriction (FGR). Methods This was a cohort analysis of individual participant data from two European multicenter trials of fetal monitoring methods for FGR: the Growth Restriction Intervention Study (GRIT) and the Trial ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

LMI-Based Pole Assignment for Uncertain Switched Systems [PDF]
不确定切换系统是一类重要的混杂系统,不确定系统主要包括两类:动态不确定性和参数不确定性。模型不确定性一般是动态不确定性和参数不确定性的组合,并可能出现在控制环的不同位置上。本文研究了一类不确定线性切换系统基于状态反馈的极点配置和鲁棒性问题。此类切换系统不仅具有未知但有界的结构不确定性,而且具有外部扰动。具体工作如下: 首先研究了一类带有状态不确定性的切换系统的极点配置和最小扰动衰减水平问题,此类切换系统不仅具有未知但有界的结构不确定性,而且具有外部扰动。利用公共Lyapunov函数方法 ...

Finding floral and faunal species richness optima among active fire regimes
Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

Abstract Coastal storms are likely to increase in frequency and become even more damaging. An unresolved policy issue is whether current residents should receive federal subsidies through such programs as the Federal Flood Insurance Program or the FEMA disaster relief program that encourage thembe encouraged to rebuild in the same locations that have ...

Freshwater biodiversity in China is threatened by multiple anthropogenic factors, and while there are some reasons to suppose it may be possible to bend the curve of biodiversity loss, the variety of threats and their likely interactions with ongoing climate change provide little basis for optimism. For example, the historic overexploitation of Yangtze

Detecting deterrence from patrol data
Abstract The threat posed to protected areas by the illegal killing of wildlife is countered principally by ranger patrols that aim to detect and deter potential offenders. Deterring poaching is a fundamental conservation objective, but its achievement is difficult to identify, especially when the prime source of information comes in the form of the ...

Study on flutter characteristics of NACA0012 flexible straight wing with high-aspect-ratio
采用三维雷诺平均N-S方程和S-A湍流模型求解展弦比为16的NACA0012弹性平直机翼的非定常气动力, 结合机翼动力学方程, 建立了机翼颤振时域分析方法。利用该方法对机翼的颤振特性、颤振过程中的变形和振动响应, 以及瞬时流场进行数值模拟和分析, 并研究材料刚度和密度对机翼颤振速度和频率的影响。结果表明, 由于展弦比较大, 且材质轻柔, 机翼会出现一定幅度的静弯曲变形。第二阶(垂向弯曲)和第三阶(扭转)振动模态的耦合作用是机翼发生颤振的原因, 且颤振频率介于这两阶模态固有频率之间 ...

Social participation challenges and response strategies identified by adults aging with a disability
Abstract Social participation is likely to decrease among older adults as disability levels increase. However, it is a modifiable determinant of health that can impact older adults' well‐being and quality of life. Thus, this secondary data analysis aimed to understand what challenges older adults aging with a mobility or vision disability face with ...
