High breakdown electric field and ultralow loss in Sb+Ho co-doped TiO2 giant dielectric ceramics induced by strongly coupled defect clusters

Journal of Materiomics
Achieving a large dielectric constant and high breakdown electric field simultaneously has been a hot and difficult topic for co-doped TiO2 ceramics. In this study, (Sb0.5Ho0.5)xTi1–xO2 (SHTOx, x = 0, 0.01, 0.02, 0.04 and 0.06) ceramics with strongly ...

Space charge modulated electrical breakdown

Electrical breakdown is one of the most important physical phenomena in electrical and electronic engineering. Since the early 20th century, many theories and models of electrical breakdown have been proposed, but the origin of one key issue, that the ...

Melatonin Levels in 89 Individuals With Smith Magenis Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT In patients with Smith–Magenis syndrome (SMS), an inverted circadian rhythm of melatonin (MT) contributes to the sleep disturbance. Standard treatment of sleep disturbance with MT often leads to extremely high daytime MT levels, resulting in even more sleep disorders. We therefore retrospectively evaluated the MT data of 89 SMS patients.

Lightning Impulse Ageing of HV Cable Insulation

, 2009
Lightning impulses can lead to accelerated ageing of extruded cables. Electrical behaviour of a dielectric material when experiencing a lightning impulse is different to that for DC or power frequency applied voltages.

Frequency‐ and Network‐Specific Changes in Functional Connectivity Reflect Pathophysiological Mechanisms across Parkinson's Disease Stages

Annals of Neurology, EarlyView.
Objective Parkinson's disease (PD) is increasingly conceptualized as a disorder of large‐scale brain networks, yet whether and how frequency‐specific functional connectivity reorganizes across stages remains poorly understood. In this study, we used high‐density electroencephalography (EEG) to characterize cortico‐cortical functional connectivity ...

Effects of Volatile Compounds on Breakdown Field Strength Measurements of Polymers

, 2022
This study investigates the effects of absorbed water and volatile compounds on measurements of the electrostatic breakdown field strength. Comparisons are made between sets of pristine samples, ones that underwent a thorough vacuum bake out, and ones ...

A cost‐effective DNA extraction protocol for long‐read sequencing in non‐model plants

Applications in Plant Sciences, EarlyView.
Abstract Premise Third‐generation sequencing has revolutionized genomics, enabling in‐depth analysis of genome sequence, structure, and epigenetic features. Yet, extracting high‐quality DNA for long‐read sequencing remains a bottleneck—particularly in non‐model plants, such as mature trees growing in natural environments, which often contain abundant ...

Long‐Range Interactions in Topological Superconducting Systems: A Mini Review

Advanced Physics Research, EarlyView.
Long‐range interacting quantum systems are surveyed in this review, with an emphasis on the long‐range topological superconductor and its variants. Long‐range interactions decaying in a power‐law manner can lead to exotic phenomena that finds no analogue in short‐range regimes.
