A multidisciplinary approach to estimating wolf population size for long‐term conservation
Conservation Biology, Volume 37, Issue 6, December 2023., 2023 Abstract The wolf (Canis lupus) is among the most controversial of wildlife species. Abundance estimates are required to inform public debate and policy decisions, but obtaining them at biologically relevant scales is challenging. We developed a system for comprehensive population estimation across the Italian alpine region (100,000 km2), involving ...

Journal of Applied Ecology, Volume 58, Issue 11, Page 2566-2578, November 2021., 2021 The development of fungicide resistance greatly threatens food security and ecological sustainability, and it is urgent need to develop agricultural practices which can ameliorate this problem. Our results show that potato crop with a genetic diversity is associated with a late blight pathogen of higher fungicide sensitivity and lower potential of ...

Gaoya dianqi, 2013 为了对接地网的腐蚀故障进行准确定位和判断,将遗传算法应用于接地网腐蚀故障诊断中。实际的接地网腐蚀故障诊断有电压法和电阻法两种思路,笔者分别根据这两种思路建立了适应度评价函数,并编制了相应的MATLAB程序。采用多层减维技术对程序进行优化,以解决接地网腐蚀故障诊断中支路变量维数多、算法后期收敛速度慢的问题。最后以一个60条支路、36个节点的接地网为例检验和对比了电压法和电阻法的诊断效果。仿真实验结果表明,在经过5层遗传算法迭代后,两种方法腐蚀诊断的误诊率和漏诊率均为0。电阻法的诊断效果略优于电压法 ...

全球能源互联网, 2021 并网型微电网的混合储能容量配置方法一般仅考虑其经济性，难以解决微电网联络线功率波动问题，会对电网产生不利影响。为了权衡混合储能的经济性与联络线功率波动平抑效果，提出了基于非合作博弈的混合储能容量优化配置方法。首先，以混合储能和联络线作为参与者，建立非合作博弈模型；其次，引入入侵杂草算法中繁殖机制和变异算子改进遗传算法，并求解模型；最后，对传统多目标优化模型、单目标优化模型和非合作博弈模型的优化结果以及传统、改进遗传算法的求解结果进行对比。结果表明：参与者进行博弈时可独立且客观优化目标函数 ...

New approach for estimating risk of miscarriage after chorionic villus sampling
Ultrasound in Obstetrics &Gynecology, Volume 56, Issue 5, Page 656-663, November 2020., 2020 ABSTRACT Objective To estimate the risk of miscarriage associated with chorionic villus sampling (CVS). Methods This was a retrospective cohort study of women attending for routine ultrasound examination at 11 + 0 to 13 + 6 weeks' gestation at one of eight fetal‐medicine units in Spain, Belgium and Bulgaria, between July 2007 and June 2018.
