Is the US Moving Toward Autocracy? A Critical Assessment
Politics &Policy, Volume 53, Issue 3, June 2025.ABSTRACT Using the theory of incremental autocratization, I illustrate in this commentary that recent developments in the United States perfectly align with this theory. In the analytical framework I use, incremental autocratization consists of six distinct step: (1) societal turmoil, (2) a proposition of radical change, (3) an electoral victory as ...

Probability Safety Analysis of Simplified CPR1000 Main Feedwater System and AP1000 Passive Containment Cooling System [PDF]
, 2016 随着数字化仪控系统在核电厂中得到越来越多的应用，其可靠性对核电安全也越来越重要。传统概率安全分析方法已在模拟仪控系统中得到广泛应用，但在分析具有新设备和新技术的数字化仪控系统时还存在不足。动态概率安全分析方法中，Markov/CCMT是较为符合数字化仪控特性的概率安全分析方法之一。 本文主要是应用故障树、Markov和Markov/CCMT三种方法对简化CPR1000主给水系统和简化AP1000非能动安全壳冷却系统分别进行安全分析，其中简化CPR1000主给水系统在设置故障时偏重于数字类故障 ...

Integrative Conservation, Volume 4, Issue 1, Page 10-19, March 2025.Brief summary: Urbanization is leading to “Nature‐deficit Disorder” that threatens children's health and the sustainable development of humanity. This study implements a new solution—the Mini Botanical Garden, which integrates some of the functions of botanical gardens into community green spaces to popularize nature education in the city.

Gaoya dianqi, 2021 配电网发生故障时,计及分布式电源的配电网可能进入孤岛划分模式运行。文中针对分布式电源接入可能带来的孤岛运行模式,提出以负荷失电损失最小为目标的孤岛划分算法。首先对失电区域建立孤岛划分模型,简化负荷节点信息,引入功率圆的概念,通过搜索孤岛划分的可行域,形成孤岛划分矩阵,进而建立孤岛划分求解方法,实现故障后配电网失电区域的负荷恢复。PG&E 69节点算例验证了文中孤岛划分方案的可行性和有效性。

Large seeds as a defensive strategy against partial granivory in the Fagaceae
Journal of Ecology, Volume 113, Issue 3, Page 598-607, March 2025.Large seeds dispersed by scatter‐hoarding granivores, such as Fagaceae acorns, tolerate partial damage to achieve higher dispersal efficiency. By demonstrating that seed size itself acts as a defensive trait, the findings provide new insights into seed size diversity and evolution, highlighting how large seeds counterbalance reserve losses to evade ...

Shuitu Baochi Xuebao, 2021 为探究不同生态修复模式对露天矿区排土场边坡产流产沙规律的影响，采用野外径流小区试验方法，对矿区排土场边坡不同生态修复模式的产流产沙进行了1个雨季的连续观测。结果表明：（1）研究区降雨年内分配不均，主要集中在汛期7—9月，该时期降雨量占到年均降雨量的77.03%，是年内径流泥沙损失最多的时期。（2）不同生态修复模式与对照（只撒播灌草种子）相比均具有减流减沙效果，但是不同生态修复模式的减流减沙效益有显著差异，减流效果从大到小依次为沙柳网格模式（64.35%）>生态棒模式（56.56%）>生态袋模式（52 ...

The (complex) effect of internet voting on turnout: Theoretical and methodological considerations
Policy &Internet, Volume 16, Issue 3, Page 607-627, September 2024.Abstract The adoption of remote internet voting can be a rather complex reform. In theory and praxis, geographical units can either decide to adopt or not to adopt i‐voting. Those that adopt it can differ in the mode of i‐voting adoption (i.e., internet‐only voting, or also in‐person voting), and the timing of adoption (i.e., some geographical units ...
