The emission of light from spark discharges [PDF]

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1946
The investigation is concerned with the transitory effects occurring in spark channels, after the discharge gap has been' bridged completely by a streamer. Observations have been made for various gases, in particular for hydrogen and argon, at pressures of the order of 1 atm.

Factors affecting the operation of laser-triggered gas switch (LTGS) with multi-electrode spark gap [PDF]

, 2007
Multi-electrode spark switches can be used for switching applications at elevated voltages or for command triggering. Symmetrical field graded electrodes allow the electrical stress across individual gaps to be controlled, thus maximising the hold off ...

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

FEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Air hydrodynamics of the ultrafast laser-triggered spark gap

, 2020
We present space and time resolved measurements of the air hydrodynamics induced by ultrafast laser pulse excitation of the air gap between two electrodes at high potential difference. We explore both plasma-based and plasma-free gap excitation.

Age‐Related Characteristics of SYT1‐Associated Neurodevelopmental Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We describe the clinical manifestations and developmental abilities of individuals with SYT1‐associated neurodevelopmental disorder (Baker‐Gordon syndrome) from infancy to adulthood. We further describe the neuroradiological and electrophysiological characteristics of the condition at different ages, and explore the associations ...

Spatial and time resolved determination of the vibrational temperature in ignition sparks by variation of the dwell time

SN Applied Sciences, 2020
The ignition process initiates the combustion in spark-ignition engines. Therefore, understanding the ignition process is an important aspect in developing more efficient combustion engines.

Prognostic Implications of Sleep Architecture for Patients Admitted to the Intensive Care Unit With Status Epilepticus

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Status epilepticus (SE) is associated with significant mortality. Sleep architecture may reflect normal brain function. Impaired sleep architecture is associated with poorer outcomes in numerous conditions. Here we investigate the association of sleep architecture in continuous EEG (cEEG) with survival in SE.

Several Methods of Reducing Discharge Energy for Intrinsic Safety Power Supply

Meikuang Anquan, 2020
In order to reduce the discharge spark energy of the intrinsic safety power supply, several measures are proposed in this paper. When the over-current protection occurs, DC-DC or AC-DC module should be turned off as quickly as possible, and the ...
