Application of electro-optic modulation technique for PD monitoring of power transformers

Partial discharge (PD) detection is an important technique for assessing the health of high voltage power transformers. A partial discharge signal within an oil-filled power transformer may reach a winding first, then travel along the winding to the ...

The causal effect of agricultural landscape simplification on Germany's grasslands during a compound drought and heatwave in 2018

American Journal of Agricultural Economics, EarlyView.
Abstract Preserving ecosystem services, along with economic and environmental benefits, will require future landscape policies to identify and incorporate relevant landscape features. In this paper, we investigate the causal effect of agricultural landscape simplification on drought‐related grassland damages.

Effects of an Inpatient Program on Medication Errors in Hospitalized People with Parkinson's Disease

Annals of Neurology, EarlyView.
Objective Hospitalized people with Parkinson's disease (PwP) face increased risks of medication errors and discharge to non‐home settings, both of which are associated with adverse outcomes. This study assessed differences in medication error rates and discharge outcomes before and after implementation of a dedicated inpatient program for hospitalized ...

Biallelic PIGB Variants Cause Motor Neuropathy with Conduction Blocks and Peripheral Nerve Hyperexcitability

Annals of Neurology, EarlyView.
Objective Glycosylphosphatidylinositol (GPI)‐anchored proteins play critical roles in nervous system function. Pathogenic variants in genes involved in GPI‐anchor biosynthesis cause early‐onset multisystem disorders known as inherited GPI deficiencies. We describe a novel neuromuscular phenotype associated with PIGB deficiency.
