The objective of my work is the simulation and analysis of the protection of electrical networks against lightning strikes. To achieve this goal, I will use the simulation programs ATP/EMTP and MATLAB/SIMULINK to simulate a lightning strike in two cases:

This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Development of a ±660 kV DC transmission line arrester
In order to improve the lightning withstand level of ±660 kV DC transmission line in China, the authors had begun to develop the ±660 kV DC line arrester since 2014, which was developed successfully in 2016.

ADP‐ribosylation: An emerging regulator of the epigenome
ADP‐ribosylation has emerged as a dynamic epigenetic signaling mechanism that modifies histones and chromatin‐associated proteins. Through coordinated PARylation and MARylation, it integrates with other histone modifications to regulate chromatin structure, transcription factor activity, and gene expression, influencing genome function and disease ...

Selection and Application of Surge Arresters for Middle-Voltage Air-Insulated Switchgears
The purpose of this thesis is to introduce readers with design of a surge arresters in four different categories. In the first part of this thesis is described theory of overvoltage, surge arresters and testing.

We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...

The online monitoring data of lightning arresters are susceptible to environmental temperature, humidity, and surface contaminants. However, conventional alarm threshold setting approaches for leakage current may result in false alarms.
