Research on Ultra‐Wideband Pulse Current Method for DC Partial Discharge Measurement

open access: yesHigh Voltage, EarlyView.
ABSTRACT The conventional pulse current method is commonly used in AC or DC withstand voltage tests with partial discharge (PD) monitoring. Because of its relatively narrow measurement bandwidth, this method tends to ignore critical information in PD waveforms, making it difficult to eliminate pulse‐type interference under DC voltage conditions, where ...

Mechanism of Quasi‐Power‐Frequency Resonant Overvoltage Triggered by Multiple Lightning Strikes in High‐Voltage Alternating Current Systems Equipped With Shunt Reactor

open access: yesHigh 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 ...

Large‐Scale Applications of Plasma Technologies: Progresses and Challenges

open access: yesHigh Voltage, EarlyView.
ABSTRACT Plasma technologies convert electrical power into energetic electrons, ions, reactive species, radiation and heat, thereby breaking through the bottleneck of purely thermal or chemical routes and bringing impressive changes to our world. This roadmap reviews the progress and challenges of plasma technologies from a large‐scale and application ...

A femtosecond time‐resolved Bragg coherent diffraction imaging experimental setup at PAL‐XFEL for nanoscale lattice dynamics studies

open access: yesJournal of Synchrotron Radiation, EarlyView.
The XSS beamline at PAL‐XFEL provides a femtosecond time‐resolved Bragg coherent X‐ray diffraction imaging setup, optimized for tracking transient lattice dynamics and nanoscale strain fields within single crystals during dynamic processes.We report on the design and operational characterization of a femtosecond time‐resolved Bragg coherent X‐ray ...

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution

open access: yesJournal of Anatomy, EarlyView.
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.
