Intelligent Controlled Dynamic Voltage Restorer for Improving Transient Voltage Quality

IEEE Access, 2023
A dynamic voltage restorer (DVR) is developed to stabilize the three-phase load voltage under the sudden grid voltage distortion conditions, including the voltage sag, swell and unbalance.

Energy efficiency enhancement using dynamic voltage restorer (DVR)

International Journal of Power Electronics and Drive Systems (IJPEDS), 2019
Dynamic voltage restorer (DVR) is a device that can compensate harmonic, voltage sag and voltage swell condition that exists in a three-phase system. Other than that, DVR can also be used to enhance the energy efficiency or energy saving by reducing excessive amount of incoming power via the reduction incoming voltage at allowable limit.

Proteogenomic Profiling of Idiopathic Pulmonary Arterial Hypertension Identifies Sex‐Differential Proteins and Candidate Therapeutic Targets

Advanced Science, EarlyView.
An integrated proteogenomic analysis of 44,137 predominantly European‐ancestry UK Biobank participants aged 40–69 years identifies 12 robust proteins associated with idiopathic pulmonary arterial hypertension. These proteins define a high‐mortality molecular endotype, support early detection and mortality prediction, reveal sex‐differential proteomic ...

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease

Arthritis &Rheumatology, EarlyView.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

Energy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...

Heel movement and foot biomechanics in aluminium nail‐on and indirect glue‐on fabric cuff shoes in horses

Equine Veterinary Journal, EarlyView.
Abstract Background Heel movement is critical to shock absorption and vascular perfusion of the equine digit. Conventional horseshoeing techniques are suspected to restrict natural hoof deformation, affecting hoof biomechanics. Several studies have explored the effects of shoeing on hoof function, though many have been limited to artificial conditions,

Spatial Patterns, Driving Forces, and Potential Grain Losses of Non‐Grain Production of Farmland in Central Yunnan Urban Agglomeration, China

Land Degradation &Development, EarlyView.
ABSTRACT The expansion of farmland non‐grain production (NGP) poses a potential threat to food security and agricultural land protection, particularly in mountainous urban agglomerations. However, the utilization patterns, driving mechanisms, and associated production‐loss effects of farmland NGP in this specific regional context remain insufficiently ...
