Plasma EV Proteomics Identifies ECM Remodeling and Inflammatory Proteins LUM and C7 as Candidate Biomarkers in FSHD

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Facioscapulohumeral muscular dystrophy (FSHD) is one of the most debilitating and common muscular dystrophies. Despite its severity, no approved therapy exists for FSHD patients. However, several therapeutic candidates are currently under development, and some have recently entered clinical trials, marking the need for reliable ...

AVR adjustment of Synchronous Generators in Weak Grids under Faulty Conditions. [PDF]

, 2013
In weak grids, an important problem with voltage stability and protections coordination of power plants exists. This problem appears because all the generation groups are connected to the same bus bar.

Review of HVDC technologies for weak grid interconnectors

Electrical Engineering
HVDC has experienced substantial growth in utilization globally, attributable to its superior capacity for transmitting large amounts of power relative to its HVAC counterpart and its increasingly competitive pricing. Voltage source converter technology, a variant of HVDC, is particularly well suited for transferring bulk offshore power, whether in ...

Mathematical model of grid‐connected inverter system in weak grid

Electronics Letters, 2015
Impedance‐based analysis is widely used to study the grid‐connected inverter system in a weak grid. The advantage of the analysis is that without knowing the accurate parameters of an inverter, its equivalent output impedance can be obtained by specific methods (e.g. the specific harmonic injection method) to investigate the system'

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
