Multi-objective decoupling control strategy for low voltage ride through under asymmetrical faults

电力工程技术
For the traditional low voltage ride through control under asymmetrical faults, due to the limited control degrees of freedom, the grid-connected inverter control suffers from the problem of not being able to simultaneously realize the output current ...

CSF Monoamine Metabolites and Cognitive Trajectory in Early Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Imaging and postmortem studies indicate that abnormalities in monoaminergic neurotransmission contribute to cognitive impairment in Parkinson's disease (PD). However, it remains uncertain if cerebrospinal fluid (CSF) monoamine metabolites can serve as biomarkers of cognitive decline in early PD.

Interpolation-Free Hybrid Bergeron–π Line Model with Accurate Zero-Sequence Impedance

Energies
Fixed-step real-time electromagnetic-transient (EMT) simulation of large power networks typically relies on parallel partitioning, where transmission-line elements serve as step-synchronous decoupling boundaries between subsystems.

MOGAD Is the Most Common Cause of Isolated Optic Neuritis in Children

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives The study aimed to characterize the clinical features, etiologies, and outcomes of isolated, first‐time pediatric ON in the post‐MOG‐IgG era. Methods This was a single‐center retrospective cohort study at Texas Children's Hospital of patients diagnosed with first‐time ON between 2018–2024, with follow‐up data collected through 2025.

Fault Type Determination on Distribution Networks Lines within Functions of Microprocessor Current Protections

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2011
The main disadvantage of the existing microprocessor current protections of distribution networks lines of 6–35 kV is a comparatively short instantaneous trip zone of the first step and insufficient sensitivity of the third step in many cases of ...

Distance protection based on dynamic phase compensation for offshore wind power low-frequency transmission line

International Journal of Electrical Power & Energy Systems
Asymmetrical faults on offshore wind power flexible low-frequency transmission lines (LFTLs) cause the fault current amplitude and phase to be constrained by weak-source control strategies at both terminals.

Risk of Retinopathy Associated with Long‐Term Use of Hydroxychloroquine in Patients with Rheumatic Diseases: A Systematic Review and Meta‐Analysis

Arthritis Care &Research, EarlyView.
Objective We aimed to estimate the prevalence and cumulative incidence of hydroxychloroquine retinopathy (HCQ‐R) and its risk factors among patients receiving long‐term HCQ with rheumatic diseases through a systematic review and meta‐analysis of observational studies that used spectral‐domain optical coherence tomography (SD‐OCT) for screening ...

A Membership Agreement Algorithm Detecting and Tolerating Asymmetric Timing Faults [PDF]

, 2006
Our paper presents a new membership agreement algorithm that address asymmetric timing faults and includes a new tool simulating TTP/C clusters. The proposed algorithm flags deviating or slightly untimely messages to assure that single marginal transmitting faults are detected and that only the faulty node will be expelled. The tool can demonstrate the

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology

Advanced Engineering Materials, EarlyView.
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Coordinated Low-Voltage Ride-Through Control of a Flywheel-Assisted Permanent-Magnet Direct-Drive Wind Power System Under Asymmetrical Grid Faults

Energies
To address fault-period DC-link overvoltage, the reduction in grid-side active-power regulation margin caused by reactive-current-priority operation, and the double-frequency current fluctuation induced by negative-sequence components under asymmetrical ...
