He jishu熔盐堆具有固有安全性和部署灵活性，能够广泛应用于多种场景。功率控制系统是确保熔盐堆安全稳定运行的关键系统之一，其在控制堆芯燃料盐温度的同时，还需要对负载变化进行快速响应，以满足基于熔盐堆的多样化复合能源系统中的潜在需求。控制目标之间存在相互影响，且执行器的数量和可调范围往往有限，因此给控制器参数的选择带来了巨大挑战。本文使用反应堆功率控制系统上普遍采用的比例-积分-微分（Proportional-Integral-Derivative，PID）控制器对堆芯温度和功率进行控制。在MATLAB ...

Using the capabilities approach to achieve people‐centered conservation
Conservation Biology, EarlyView.Abstract Top‐down interventions carried out by state and nonstate institutions to conserve biodiversity and improve the lives of forest‐proximate people (FPP) in the Global South tend to reflect economistic understandings of human well‐being. More progressive and people‐centered conservation projects are guided by normative visions of how the world ...

Optimizing biodiversity offsetting for habitat succession and colonization dynamics
Conservation Biology, EarlyView.Abstract Biodiversity offsetting aims to compensate for ecological losses from development through conservation and restoration. However, its long‐term outcomes under repeated impact–offset cycles remain uncertain. Using a conceptual forest succession model, we evaluated how offset outcomes are affected by interactions among compensation scale ...

How endorser attributes influence conservation communication
Conservation Biology, EarlyView.Abstract Conservation communication often uses the celebrity endorsement strategy. However, robust evidence regarding its effectiveness is still limited. More importantly, practitioners do not have guidelines for selecting an ideal endorser because there is no clear consensus on what endorser attributes are most critical.

He jishu编码孔径成像广泛应用于低能量（<0.2 MeV）伽马成像领域，其在中高能段（0.2~5 MeV）的应用也在得到逐步拓展。为解决中高能伽马成像中串扰光斑、内散射增强所导致的成像性能恶化的问题，提出了基于推测首次反应位置的降噪方法。通过使用掺铈钆铝镓石榴石晶体（Cerium-doped Gadolinium Aluminum Gallium Garnet，GAGG：Ce）与硅光电倍增管（Silicon Photon Multiplier，SiPM）阵列耦合，并使用A5202采集模块读出 ...

面向工程应用的先进绝热压缩空气储能模型及先进㶲分析 [PDF]
全球能源互联网先进绝热压缩空气储能（advanced adiabatic compressed air energy storage system，AA-CAES）仿真建模及分析是其工程实践的基础。然而，目前模型一般基于理想工况建立，分析结果与实际工况相偏差较大，无法指导工程应用。为此，在传统热力学模型基础上，考虑了空气流动阻力损失和能量转换设备损耗等因素，建立了面向工程应用的AA-CAES模型并以200 MW盐穴AA-CAES系统为例进行了分析。同时，对系统效率分析方法进行改进并对其进行了先进分析。结果表明 ...

A Systematic Scoping Review of Self‐Regulated Learning With AI in Language Education
International Journal of Applied Linguistics, EarlyView.ABSTRACT The rapid development of artificial intelligence (AI) technology has brought new opportunities for second/foreign language (L2) education while also raising concerns about the use of AI tools. This systematic scoping review provides a snapshot of the current state of research situated at the intersection of self‐regulated learning (SRL) and AI
