Rare Metals, EarlyView.ABSTRACT Lung cancer remains the leading cause of cancer‐related deaths worldwide, yet immune checkpoint blockade (ICB) is often compromised by an immunosuppressive tumor microenvironment (TME) with acidosis, hypoxia, and poor T cell infiltration. Here, we develop a TME‐responsive nanoplatform (MgH2@Lip/PD‐L1) that couples hydrogen gas therapy with PD ...

A Multifunctional Reducing Molecular Dopant for 16% Efficient Tin Perovskite Solar Cells
Rare Metals, EarlyView.ABSTRACT Although lead‐based photovoltaics have seen remarkable progress, tin‐based perovskite solar cells (Sn‐PSCs) continue to face challenges due to their limited power conversion efficiency and insufficient operational stability. The primary cause of this performance gap is the susceptibility of Sn2+ to oxidation, which promotes rapid defect ...

Journal of Linguistic Anthropology, Volume 35, Issue 2, August 2025.Abstract This article argues that social actors' media ideologies about digital interfaces are key to the enregisterment of online activities. Focusing on an online register emergent from user activities around Year, Hare, Affair (YHA)—a state‐aligned Chinese animation—I explore how different metadiscourses evaluate this register by entextualizing ...

Policy &Internet, Volume 16, Issue 3, Page 628-642, September 2024.Abstract Infrastructure siting has been shown to lead to high contestation across political systems. To counteract this, policymaking has introduced participatory instruments that were recently supplemented by web‐based tools. Drawing on theoretical perspectives on policy conflict, this paper investigates how different conflict intensities reflected in

Infant Mental Health Journal: Infancy and Early Childhood, Volume 45, Issue 2, Page 234-246, March 2024.Abstract Improving parental sensitivity is an important objective of interventions to support families. This study examined reliability and validity of parental sensitivity ratings using a novel package of an e‐learning tool and an interactive decision tree provided through a mobile application, called the OK! package.

Dianci bileiqi, 2018 雷电感应过电压导致的10 k V配电线路跳闸事故十分频繁,需要合理计算线路雷电感应跳闸率并采取针对性防护措施。利用EMTP中的MODEL模块编程计算线路雷电感应过电压,建立线路模型考虑线路闪络跳闸情况,利用区间统计法求取配电线路雷电感应跳闸率,分析线路工频电压对感应跳闸率的影响,最后讨论安装避雷器的防护效果。分析结果表明:配电线路三相感应过电压波形较为类似,过电压幅值相差不大;雷击点距离线路越近,感应过电压可能引发的线路跳闸次数越多;线路工作电压对雷电感应跳闸率的影响很小,基本可以忽略 ...

Dianci bileiqi, 2019 为了研究雷击线路杆塔时埋地油气管道的防护措施对降低防腐层感应电压防护效果的影响,本文通过CDEGS软件建立了埋地油气管道、线路杆塔及接地装置的仿真计算模型,对排流带的布置方位、与管道的连接方式、与管道的距离、排流带的长度对降低防腐层感应电压的效果进行了分析,得到如下结论:排流带靠近杆塔侧敷设比背向杆塔侧敷设效果更优;排流带与管道连接点数量对管道防腐层感应电压影响不大,但管道上排流带连接点与杆塔越接近效果会稍好;排流带与管道之间的距离对管道防腐层感应电压影响不明显 ...

500/220kV同塔四回输电线路接地开关开合感应电压—感应电流能力研究
Gaoya dianqi, 2013 同塔多回输电线路有效解决了电网建设与输电走廊紧缺之间的矛盾,但对接地开关提出了严苛的要求。笔者以500 kV祯宝甲乙线与220 kV东莆甲乙线同塔四回架设为例,对感应电压和感应电流进行了理论分析,采用电磁暂态仿真程序（ATP-EMTP）计算了两种不同运行工况下,停运线路的感应电压和感应电流。发现计算结果超过了标准规定的接地开关能够开合的B类感应电压、电流的要求。依据计算结果对500 kV东莞站采用的220 kV JW6-252/J50型接地开关进行了开合超B类感应电压、电流的试验。在开断电磁感应电压2 ...
