Simulation of beam-induced plasma in gas-filled rf cavities

, 2017
Processes occurring in a radio-frequency (rf) cavity, filled with high pressure gas and interacting with proton beams, have been studied via advanced numerical simulations. Simulations support the experimental program on the hydrogen gas-filled rf cavity

VO2 Oscillator Circuits Optimized for Ultrafast, 100 MHz‐Range Operation

Advanced Electronic Materials, EarlyView.
The present study demonstrates ultrasmall (≈30 nm) VO2 Mott memristor‐based oscillators which enter the >100 MHz frequency range via device scaling and optimization of the circuit layout for high frequency operation. Time‐resolved investigation of switching dynamics along with circuit‐level and physics‐based electrothermal simulations identify physical

Promoting Dentin Bridge Formation Through N-Acetyl-L-Cysteine Application in Rat Molar Pulpotomy: An Experimental Study

Journal of Functional Biomaterials
Pulpotomy is performed when tooth decay reaches the dental pulp or when the crown is fractured due to trauma. Mineral trioxide aggregate (MTA) is commonly used in pulpotomy, but its prognosis can be variable.

Equitable Collaboration Between LMIC and HIC Researchers, Part I: A Preliminary Framework for Capacity Building in Psychiatric Genetics Research

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT International collaborations between high‐income countries (HICs) and low‐ and middle‐income countries (LMICs) have become increasingly essential in advancing global health, particularly within psychiatric research. These partnerships not only accelerate scientific discovery and enhance public health, but they also bring to light significant ...

5'-methylthioadenosine modulates the inflammatory response to endotoxin in mice and in rat hepatocytes [PDF]

, 2004
5'-methylthioadenosine (MTA) is a nucleoside generated from S-adenosylmethionine (AdoMet) during polyamine synthesis. Recent evidence indicates that AdoMet modulates in vivo the production of inflammatory mediators.

Spermidine reproduces the anti‐inflammatory effects of intermittent fasting and prevents urate and calcium pyrophosphate crystal‐induced inflammation

Arthritis &Rheumatology, Accepted Article.
Background Gout due to the formation of monosodium urate (MSU) crystals and calcium pyrophosphate (CPP) deposition disease are two major types of microcrystalline pathologies in adults. They are responsible for recurrent flares that rely on interleukin (IL)‐1β via activation of the NLRP3 inflammasome.
