Low‐Frequency Oscillation Suppression of FDR Time‐Domain Diagnostic Waveforms for Cable Defects Based on Splicing Technology

open access: yesHigh Voltage, EarlyView.
ABSTRACT A time domain pulse (TDP) based on the frequency domain reflectometry (FDR) method can be used to diagnose the insulation state of cable defects. However, because of the limitations of the FDR test instrument, the lack of a reflection coefficient spectrum (RCS) in the low‐frequency band (LFB) can result in low frequency oscillation in the time

Deterioration Law of Mechanical Properties of Insulation Pressboard Under Multifield Coupled Ageing

open access: yesHigh Voltage, EarlyView.
ABSTRACT Converter transformers can experience progressive deterioration of their oil–pressboard insulation under elevated temperature, combined AC–DC electrical stress and persistent mechanical vibration. This study investigates how mechanical vibration affects the mechanical properties of insulation pressboard and clarifies the associated microscopic

Inducible defences, chemical aposematism and the spatial ecology of plant–herbivore interactions in tall goldenrod, Solidago altissima L.

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants can respond to herbivore attack by inducing resistance traits that affect subsequent herbivore performance and behaviour. Here, we investigate how such induced responses in Solidago altissima L.

Choose, Compose, Contemplate: Semantic Theorizing in Management Research

open access: yesBritish Journal of Management, EarlyView.
Abstract By analysing life stories through a reflexive semantic theorizing process, this article introduces an alternative to many conventional coding‐based qualitative analysis techniques. Rather than relying on coding techniques that often strip narrative data of its context and nuance, following the proposed approach helps preserve the richness and ...

Defining and measuring homicide rates for birth cohorts: Methodological and theoretical challenges and solutions

open access: yesCriminology, EarlyView.
Abstract Social scientists have long been interested in understanding how age, period, and cohort effects shape long‐term homicide trends. Yet fundamental measurement challenges remain pervasive in estimating age‐specific homicide rates for birth cohorts.
