Parameter identification using moment of velocity [PDF]
Royal Society Open Science, 2019 Many physical systems can be adequately modelled using a second-order approximation. Thus, the problem of system identification often reduces to the problem of estimating the position of a single pair of complex–conjugate poles.

Dianci bileiqi, 2023 金属氧化物限压器(MOV)是串联补偿装置电容器组重要的过电压保护设备。当限压器组中某一台MOV单元出现贯穿性击穿故障时，一旦超出MOV的压力释放能力，易造成MOV爆炸。为了验证MOV在实际电流工况下的可靠性，笔者根据国内串补采用的无垫块(A结构)和有垫块B结构)两种MOV结构，建立了瞬态热气流场等效计算模型。针对型式试验、实际故障和极端故障的3种电流工况下，MOV单元出现贯穿性击穿故障时，其内部的气体发热和扩散情况进行了仿真研究。研究表明：MOV压力释放过程中，MOV内部压强增大的同时 ...

Real-World Utilization of Molnupiravir during the COVID-19 Omicron Surge in Israel
Epidemiologia, 2023 Molnupiravir (MOV) was introduced in Israel in January 2022 during the SARS-CoV-2 Omicron surge for high-risk patients contraindicated for nirmatrelvir/ritonavir. This retrospective cohort study aimed to describe characteristics of patients offered COVID-

Dianci bileiqi, 2023 目前对串补装置用金属氧化物限压器(MOV)进行防爆性能试验时，均没有考虑故障时串补电容器组放电电流的影响。即使MOV通过了国标要求的型式试验，其瓷外套在MOV击穿故障情况下也可能发生粉碎性爆炸，因此有必要对真实故障电流下MOV的防爆性能展开研究。以某500 kV交流线路带串联补偿工程MOV瓷外套炸裂故障为研究背景，对故障时流过MOV的电流与型式试验电流的不同、故障工况与型式试验工况下MOV瓷套所受压力和瓷套尺寸参数对压力释放的影响进行了计算分析，结果表明故障工况下MOV瓷套压强峰值远大于型式试验工况 ...

Embedding non-projective Mori Dream Spaces [PDF]
, 2019 This paper is devoted to extend some Hu-Keel results on Mori dream spaces (MDS) beyond the projective setup. Namely, $\Q$-factorial algebraic varieties with finitely generated class group and Cox ring, here called \emph{weak} Mori dream spaces (wMDS ...

Update on Multiple Ovulations in Dairy Cattle
Animals, 2018 This review updates the causal mechanisms and risk factors for multiple ovulations (MOV) in cattle. Clearly, MOV can lead to twin pregnancies, which negatively affects the health, production, and reproduction of cows. Therefore, a better understanding of

Temporal discrimination: Mechanisms and relevance to adult-onset dystonia [PDF]
, 2017 Temporal discrimination is the ability to determine that two sequential sensory stimuli are separated in time. For any individual, the temporal discrimination threshold (TDT) is the minimum interval at which paired sequential stimuli are perceived as ...
