Behavior of ions from medium-density plasma in electric field created by plate–grid–plate geometry

AIP Advances, 2022
The behavior of the ions from a medium-density plasma in an electric field created by the plate–grid–plate geometry was simulated with a two-dimensional one-fluid model in which electrons are assumed to be in thermal equilibrium, and the accuracy of the ...

A Topology Optimization Procedure for Assisting the Design of Nuclear Components

Journal of Nuclear Engineering, 2021
In this paper, we show that a module implemented in the MCNP transport code to perform sensitivity analyses can be diverted to perform topology optimizations of nuclear equipment.

A Novel Trans-Tracheostomal Retrograde Inhalation Technique Increases Subglottic Drug Deposition Compared to Traditional Trans-Oral Inhalation

Pharmaceutics, 2023
Subglottic stenosis represents a challenging clinical condition in otolaryngology. Although patients often experience improvement following endoscopic surgery, recurrence rates remain high.

Bayesian inference of polymerase dynamics over the exclusion process

Royal Society Open Science, 2023
Transcription is a complex phenomenon that permits the conversion of genetic information into phenotype by means of an enzyme called RNA polymerase, which erratically moves along and scans the DNA template.

Smart-particle application for describing the probabilistic particle transport dynamics above threshold conditions [PDF]

مهندسی عمران شریف, 2022
Coarse particle motion behavior plays a crucial role in sediment and hydraulic engineering, though its physics is still not fully understood. Disregarding the inherently stochastic nature of the sediment transport leads to various equations for bedload ...

An Electrostatic Method for Manufacturing Liquid Marbles and Particle-Stabilized Aggregates

Frontiers in Chemistry, 2018
We have developed a method for transferring particles from a powder bed to a liquid droplet using an electric field. This process has been used to create liquid marbles with characteristics not normally found in those formed by direct contact methods ...

PERFORMANCE STUDY OF GLOBAL WEIGHT WINDOW GENERATOR BASED ON PARTICLE DENSITY UNIFORMITY [PDF]

EPJ Web of Conferences, 2021
The variance reduction techniques are necessary for Monte Carlo calculations in which obtaining a detailed calculation result for a large and complex model is required. The GVR method named as global weight window generator (GWWG) was proposed by the FDS
