ABCA12 Frameshift Deletion in Domestic Cats With Ichthyosis Fetalis
Veterinary Dermatology, EarlyView.ABSTRACT Background Ichthyosis fetalis (IF), also known as harlequin ichthyosis, is a rare and often fatal autosomal recessive congenital skin disorder. It is characterized by thickened, hard skin plaques and deep skin fissures that limit mobility and cause malformations of the eyes, lips and ears.

Dianci bileiqi, 2022 目前，我国城市中低压配电网电容电流骤增且消弧线圈补偿能力不足问题突出，为解决由此带来的单相接地故障电弧难以自熄问题，故障相接地消弧技术在配电网逐渐开展试用，故障相准确辨识是该技术可靠熄弧的基础。本研究分析故障后三相电压暂态信号，得到故障相暂态电压波形与非故障相极性相反的特征，提出利用故障相和非故障相暂态电压波形相似度判断故障相的方法；采用Matlab&Simulink建立10 kV典型配电网模型和电弧故障模型，并在不同中性点接地方式下改变过渡电阻、故障点距离、故障相角、间歇性接地等弧光接地故障条件 ...

How New Issues Become Polarized: Partisan Triggers and Subsystem Shopping in Early AI Policymaking
Policy &Internet, Volume 18, Issue 1, March 2026.ABSTRACT Early AI policymaking in the United States appeared bipartisan, but subsequent developments raise the question of whether AI policy will become more polarized over time. To examine how partisanship takes root around novel policy issues, we perform a mixed‐methods study, analyzing survey data from 129 state legislators in 44 states and ...

Analysis of Active Power Measurement Error [PDF]
, 2014 用对称分量分析了三序功率与三相功率间的关系,得出三相功率是同一相序的电压与电流的对称分量函数;三相电路平衡时,用两瓦法能正确测量三相三线电路功率,当三相四线电路不平衡时,用两瓦法测量功率存在误差。Using symmetrical components,this paper analyzes the relationship between 3-sequence power and 3-phase power and concludes that 3-phase power is a function ...

Policy &Internet, Volume 18, Issue 1, March 2026.ABSTRACT Over the past two decades, Voting Advice Applications (VAAs) have become widely used tools that provide personalized political information to help voters make informed choices and strengthen democratic processes. However, little research has examined their potential unintended effects.

Shuitu Baochi Xuebao, 2000 建立侵蚀性降雨标准，是为了区分发生和不发生侵蚀和降雨事件，从而大大减少计算降雨侵蚀力的工作量，并提高土壤侵蚀预报精度。利用陕西团山沟小流域及所在3个小区1961－1969年的降雨过程资料，以漏选和多选降雨事件的降雨侵蚀力相等为原则，分别建立了黄土高原坡面侵蚀的侵蚀性降雨雨量标准12mm，平均雨强标准0.04mm/min，最大30min雨强标准0.25mm/min。其中时段雨强标准筛选精度最高，可剔除88％以上的降雨事件，只有5.3％的错选度。其次是平均雨强标准，雨量标准筛选精度最差 ...

Zhejiang Daxue xuebao. Lixue ban, 2011 在土地利用/覆盖变化监测中，通常要对多时相遥感影像进行辐射归化处理，使得影像间的成像差异减小，相同地物的光谱特征相似.本研究利用两时相ETM+影像，精确选取不变像元，采用分段线性回归，探讨一种自动辐射归化处理方法.研究方法充分考虑了影像间成像条件的差异，通过影像对应波段差值直方图剔除变化像元来有效选取不变像元，将不变像元划分为暗、灰和亮3类并分级确定校正系数进行辐射归化处理.结果分析表明该方法具有一定优势.
