Cumulative degradation of electrical properties in polypropylene insulation for AC cables under repeated impulse voltage stress

open access: yesHigh Voltage
In modern power transmission systems, AC cables are increasingly integrated with overhead lines, forming hybrid networks. These cables are frequently exposed to repeated impulse voltages from the overhead lines.

Onasemnogene Abeparvovec in Patients With SMA: Interim Results of the RESTORE Registry in Japan

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective There are limited real‐world data regarding the safety and effectiveness of onasemnogene abeparvovec (OA; Zolgensma) infusion, a one‐time gene replacement therapy, for Japanese patients with spinal muscular atrophy (SMA). We aimed to improve understanding of the real‐world outcomes for OA in Japan.

Analytical Expression for Sound Transmission Loss Calculation: An Improvement to the Existing Method after Singh and Katra [PDF]

open access: yes, 2009
An analytical expression for measuring of sound transmission loss (TL) has been developed by using two microphones, an impedance tube and an impulse sound source as a proposed improvement to the existing procedure after Singh and Katra (1978).

Hardware and power management for high power impulse magnetron sputtering

open access: yes, 2019
The work that led to the development of the HiPIMS technique was initiated at the Moscow Engineering and Physics Institute (MEPhI) in the late 1960s, where high power pulses were applied to diode sputter sources.

Interaction of Intraprocedural Antiplatelets and Intravenous Thrombolysis in Acute Intracranial Stenting: RESISTANT Registry Subanalysis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction/Objective Acute intracranial stenting during endovascular thrombectomy (EVT) for ischemic stroke requires intraprocedural antiplatelet therapy (APT) to maintain patency. However, the hemorrhagic risk of combining APT with intravenous thrombolysis (IVT) remains uncertain.

Clinical Practice Guideline for Evaluation and Management of Peripheral Nervous System Manifestations in Sjögren's Disease

open access: yesArthritis Care &Research, EarlyView.
Objective Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies.

International macroeconomic fluctuations and the current account [PDF]

open access: yes
Intertemporal models of the current account generally assume that global shocks do not affect the current account. We use this assumption to identify global and country-specific shocks in a bivariate VAR.

Peculiarities of Non-Stationary Temperature Distribution of Optical Non-Transparent Anisotropic Thermoelement at Impulse Ray Excitement

open access: yesФізика і хімія твердого тіла, 2016
The solutions of non-stationary equation of thermoconductivity for the optical non-transparent thermoelement at impulse ray excitement are presented in the paper for two time ranges: when the ray current falls (0<t<tau) and when it stops (t<tau).

Low voltage disk varistors under non-standard high current derivative impulse environment

open access: yes, 2016
In this study, the behavior of low voltage disk varistors was analyzed under oscillatory type non-standard high current derivative impulses. The experiment was performed using 20 ram disk varistors with different nominal operating voltages of 14, 30, 40,
