Time‐Domain Geoelectrical Modeling and Experimental Validation of Ground Potential Rise in Multilayer Soil Structures during Fault Events

Energy Science &Engineering, EarlyView.
This study develops a time‐domain geoelectrical model of ground potential rise (GPR) in multilayer soil that couples electromagnetic field theory with nonlinear fault arc resistance. Finite‐element simulations calibrated against scaled fault‐injection experiments reproduce measured GPR and step/touch voltages within 4.7% error, revealing that steady ...

RTA‐408 Enhances Radiosensitivity and Inhibited Tumor Progression via JNK Pathway in Glioblastoma

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Glioblastoma (GBM) is an aggressive brain tumor with poor prognosis owing to its high invasiveness and resistance to therapy. RTA‐408, a synthetic triterpenoid and nuclear factor erythroid 2‐related factor 2 activator, exhibits anti‐inflammatory and anti‐cancer properties; however, its effects on GBM remain unclear. This study investigated the

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

People and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Improving the computational accuracy of the dynamic electro-geometrical model using numerical solutions

Scientific Reports, 2022
The dynamic electro-geometrical model has been applied in various studies to investigate the probability of a lightning strike to parts of a structure. The numerical computation of the dynamic electro-geometrical model (DEGM) follows an iterative step by

Organic Representation as a Critical Media Approach to Leadership Studies in Popular Culture

New Directions for Student Leadership, Volume 2025, Issue 185, Page 75-80, Spring 2025.
ABSTRACT This article applies the critical media concept of organic representation to leadership studies as an analytic of how various creators in popular culture today are not just writing inclusive storytelling but, more notably, modeling new modes of production and self‐presentation that are actively challenging hegemonic industry practices and ...

Investigating Spatial‐Temporal Optical Emission Spectroscopy of Unstable Positive Leaders in Long Sparks Under Atmospheric Pressure

High Voltage, EarlyView.
ABSTRACT This study explores exciting state species and reaction pathways in positive leaders to better understand the breakdown mechanisms of long air gap discharges and natural lightning. Emission spectra from an unstable positive leader in a 1 m rod‐plate air gap under switching impulse voltages were observed, spanning 300–800 nm.

Analysis of characteristics of lightning disaster and risk zoning in Ningbo Area(宁波地区雷电灾害特征分析及风险区划)

Zhejiang Daxue xuebao. Lixue ban, 2014
根据宁波地区ADTD闪电定位系统2010~2012年的地闪监测数据、雷灾资料以及2012年宁波地区人口及GDP数据，选取年平均地闪密度、单位面积雷灾频数、经济损失、人员伤亡、人员易损、经济易损6项指标，在详细分析宁波雷灾分布特征的基础上，采用主成分分析法对宁波各县地区雷灾易损性指标进行综合评价，并利用分层聚类分析法得出：政治经济文化中心的海曙区为雷灾极高易损区，经济发达的江东区以及工业基地镇海区为高易损区，江北区为中易损区，鄞州区、北仑区、象山县、宁海县、奉化市为低易损区，慈溪市和余姚市为极低易损区.
