How Do the Components of Social Capital Reduce COVID‐19 Vaccine Hesitancy? Lessons From a Canadian National Survey

open access: yesWorld Medical &Health Policy, Volume 17, Issue 4, Page 870-882, December 2025.
ABSTRACT This paper theorizes that not all components of social capital reduce vaccine hesitancy. Specifically, it hypothesizes that institutional trust, trust in experts, and social networks reduce vaccine hesitancy, while generalized trust and civic participation do not influence vaccine hesitancy.

The Empty State: Governing the Voids in a Projected Conflict‐Torn Yemen

open access: yesPolitics &Policy, Volume 53, Issue 5, October 2025.
ABSTRACT This study introduces the concept of the “Empty State” to explain a form of state dysfunction in Yemen, where state institutions exist but are stripped of their governance authority. While frameworks on fragile or failed states emphasize the weakness or collapse of state capacity, the Empty State highlights the persistence of symbolic ...

Simple sequence repeats and their expansions: role in plant development, environmental response and adaptation

open access: yesNew Phytologist, Volume 247, Issue 2, Page 504-517, July 2025.
Summary Repetitive DNA is a feature of all organisms, ranging from archaea and plants to humans. DNA repeats can be seen both in coding and in noncoding regions of the genome. Due to the recurring nature of the sequences, simple DNA repeats tend to be more prone to errors during replication and repair, resulting in variability in their unit length ...

软件定义传送网北向接口TAPI模型与实现

open access: yesGuangtongxin yanjiu, 2018
软件定义传送网(SDTN)通过将控制功能与传送功能分离,对传送网的网络资源和状态进行逻辑集中控制,实现传送网络的可编程性和自动化控制,构建面向业务应用的灵活、开放和智能的传送网络体系架构。在SDTN体系架构中,北向接口是连接SDTN控制器与上层应用的重要纽带,但目前仍没有统一的标准,给SDTN的发展带来了困难。文章对当前热门的北向接口信息模型传输应用编程接口(TAPI)进行了探讨,结合SDTN协同控制器设计实现了TAPI北向接口,并测试验证了TAPI北向接口信息模型的有效性和互操作性 ...

分布式光伏接入对配网系统的暂态特性影响研究

open access: yesDianci bileiqi, 2023
随着大量分布式光伏接入配电网,电力系统负荷侧的动态特性产生显著变化,尤其是配电网发生故障时,光伏的有功和无功响应对配网产生较大影响,因此,需要对分布式光伏接入对配网系统的暂态特性进行建模分析。基于光伏并网系统传统结构及控制方式,提出分别适用于低电压和高电压故障下,有功与无功解耦的逆变器保护控制策略,并对模型的高低电压穿越能力进行仿真,并基于逆变器实际电压穿越检测报告进行检验,验证了该光伏并网系统模型具备规定的故障穿越能力。由北京地区某光伏电站实际配网结构、设备参数和光伏控制参数 ...
