Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background SOX1 antibody‐positive paraneoplastic neurological syndromes (PNS) exhibit significant population‐specific clinical heterogeneity. While Western cohorts predominantly manifest Lambert‐Eaton myasthenic syndrome (65%–80%), comprehensive clinical characterization and treatment response data in Asian populations remain critically ...

Optimal Power Flow for Unbalanced Bipolar DC Distribution Grids
IEEE Access, 2018 The emergence of distributed energy resources can lead to congestion in distribution grids. DC distribution grids are becoming more relevant as more sources and loads connected to the low voltage grid use dc. Bipolar dc distribution grids with asymmetric loading can experience partial congestion resulting in a nodal price difference between the two ...

A multifunctional dynamic voltage restorer for power quality improvement [PDF]
, 2018 Power quality is a major concern in electrical power systems. The power quality disturbances such as sags, swells, harmonic distortion and other interruptions have an impact on the electrical devices and machines and in severe cases can cause serious ...

Fluid Biomarkers of Disease Burden and Cognitive Dysfunction in Progressive Supranuclear Palsy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Identifying objective biomarkers for progressive supranuclear palsy (PSP) is crucial to improving diagnosis and establishing clinical trial and treatment endpoints. This study evaluated fluid biomarkers in PSP versus controls and their associations with regional 18F‐PI‐2620 tau‐PET, clinical, and cognitive outcomes.

Reactive Power Compensation and Imbalance Suppression by Star-Connected Buck-Type D-CAP
Energies, 2019 Reactive power and negative-sequence current generated by inductive unbalanced load will not only increase line loss, but also cause the malfunction of relay protection devices triggered by a negative-sequence component in the power grid, which threatens

Meaningful Resolution of the IEEE Std. 1459 Unbalanced Power
IEEE Transactions on Power Systems, 2011 This letter present a new resolution of the IEEE Std. 1459 unbalanced power (SU1). The resolution is intended to achieve a better quantification of the power terms included in SU1. The new definitions improve the quantification of the unbalance phenomena presented in the IEEE Std. 1459.

Reactive Compensation Planning in Unbalanced Electrical Power Systems
Energies, 2022 This research focuses on finding the optimal location of reactive compensation in an unbalanced electrical power system (EPS). An EPS is named unbalanced when there is uncertainty in the behaviour of the power demand, which causes changes in the voltage profile and angle of each of the electrical power phases.

Symbolical Analysis of RF-Network Problems using Mason’s Rule [PDF]
, 2012 We briefly review Mason’s rule for the computation of RF-network problems and show its implementation into the software package freeMASON. This tool solves symbolically Mason’s rule for any wave quantity and allows to derive analytical expressions as ...
