Directed electron transport through ballistic quantum dot under microwave radiation

, 2005
Rectification of microwave radiation by asymmetric, ballistic quantum dot is observed. The directed transport is studied at different frequency (1-40 GHz) temperatures (0.3K-6K)and magnetic field.

Persistent currents in multicomponent Tomonaga-Luttinger liquid: application to mesoscopic semiconductor ring with spin-orbit interaction

, 2004
We study persistent currents in semiconductor ballistic rings with spin-orbit Rashba interaction. We use as a working model the multicomponent Tomonaga-Luttinger liquid which arises due to the nonparabolic dispersion relations of electrons in the rings ...

Implementation of MPMM ballistic model for calculation of differential coefficients for TFTs according to NATO STANAG 4119 1

Strategos, 2021
MPMM ballistic model (modified point mass model) is used to calculate all necessary ballistic trajectory elements (range, time of flight, angle of fall, maximum ordinate, differential coefficients, etc.) for classical spin-stabilized artillery projectiles.

Effect of ballistic exercise program on shoulder dynamic stability, throwing performance and shoulder strength among university level female cricket bowlers

Bangabandhu Sheikh Mujib Medical University Journal
Background: Bowling in cricket is a ballistic movement requiring rapid force generation. The Thrower's Ten and Ballistic Six programs are widely used for overhead athletes to enhance shoulder performance. Unlike general ballistic exercises, the Ballistic

Turbulent pair dispersion in the presence of gravity

New Journal of Physics, 2015
Turbulent pair dispersion of heavy particles is strongly altered when particles of two different Stokes numbers (bidisperse) are considered, and this is further compounded when a uniform gravitational acceleration is present.

Reverse design of solid propellant grain based on deep learning: Imaging internal ballistic data

Defence Technology
The reverse design of solid rocket motor (SRM) propellant grain involves determining the grain geometry to closely match a predefined internal ballistic curve. While existing reverse design methods are feasible, they often face challenges such as lengthy

Failure after operative repair is higher for ballistic femoral neck fractures than for closed, blunt-injury fractures: a multicenter retrospective cohort study

Trauma Surgery & Acute Care Open
Introduction The purpose of this study was to describe the outcomes after operative repair of ballistic femoral neck fractures. To better highlight the devastating nature of these injuries, we compared a cohort of ballistic femoral neck fractures to a ...

Research on ballistic performance of green shear thickening functionalized fabric based on solid waste modification

Materials & Design
Based on the solid waste-based modification, green shear-thickening functionalized ballistic composites were prepared. Silica aerosols were obtained from solid waste diatomaceous earth through sol–gel preparation, gel aging, and supercritical drying. The
