High Voltage, EarlyView.ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.

High Voltage, EarlyView.ABSTRACT This paper investigates the generation mechanism of quasi‐power‐frequency resonant overvoltage triggered by multiple lightning strikes in high‐voltage alternating current (HVAC) systems equipped with shunt reactors. Based on field measurements from a 500 kV AC system, equivalent and simplified circuit models have been established to analyse ...

Effect of indirect lightning strike to 66kV transmission line in Java-Bali system
MATEC Web of Conferences, 2018 Based on Java-Bali grid disturbance data, the 66kV transmission lines that is close to or intersect with 150kV or 500kV transmission line is often experienced earth fault due to insulator flashover.

The Issue of Pre‐Islamic Arabic Christian Poetry Revisited
Arabian Archaeology and Epigraphy, EarlyView.ABSTRACT Is only very little Arabic Christian poetry extant from pre‐Islamic times? While distancing myself from Louis Cheikho's (1859–1927) view that almost all pre‐Islamic poets were Christians, I contend in this article that some of them indeed were.

Market regulation and productivity: The case of the Canadian Wheat Board
American Journal of Agricultural Economics, EarlyView.Abstract Changes to regulatory environments influence firm‐level incentives, which can move the productivity frontier or reposition firms within an existing frontier. Estimating causal effects of policy changes requires a credible counterfactual for productivity in the absence of policy change.

American Anthropologist, EarlyView.ABSTRACT The evolutionary study of human dispersal is a key topic in biological anthropology. However, recent research has revealed inconsistencies between molecular and anatomical data across different timescales and geographic regions. Despite increased interdisciplinary dialogue, these discordances are rarely analyzed in depth or interpreted for ...

A Strike from the Air: Cerebral Hemorrhage after a Lightning Strike
Indian Journal of NeurosurgeryLightning strikes pose a rare but catastrophic risk for a variety of injuries, including damage to the central nervous system. We present the case of a 79-year-old farmer who survived a lightning strike directly in the chest resulting in an intracerebral

No added cost: Emotion recognition in co‐occurring ADHD and ASD
British Journal of Clinical Psychology, EarlyView.Abstract Objectives Facial emotion recognition (FER) is fundamental for social interaction, yet this ability is often impaired in attention‐deficit/hyperactivity disorder (ADHD) or autism spectrum disorder (ASD). While research has documented these difficulties, two key questions remain: Are these deficits specific to recognising emotions or do they ...

Punchline with(out) purpose: Integrating research on instructional humour and seductive details
British Journal of Educational Psychology, EarlyView.Abstract Introduction We integrated research on instructional humour and seductive details to investigate when affiliative course‐related humour is effective or rather ineffective for learning. We assumed that instructional humour without a cognitive function (irrelevant humour) would have detrimental effects on learning performance resembling the ...
