Force exerted on particle bunch propagating near plasma-vacuum boundary [PDF]
, 2020 If a charged particle bunch propagates near a plasma-vacuum boundary, it excites a surface wave and experiences a force caused by the boundary. For the linearly responding plasma and ultra-relativistic bunch, the spatial distribution of excited fields is calculated, and the force exerted on a short and narrow bunch is approximated by elementary ...

International Review of Sport and Exercise Psychology, 2021 Prior self-control exertion is consistently reported to cause decrements in subsequent physical performance. However, research into the explanatory mechanisms underpinning the effect is limited and has not been assessed under a meta-analytical lens ...

Acoustic radiation torque on a particle in a fluid: an angular spectrum based compact expression [PDF]
, 2020 In this work, we derive a set of compact analytical formulas expressing the three-dimensional acoustic radiation torque (ART) exerted on a particle of arbitrary shape embedded in a fluid and insonified by an arbitrary acoustic field. This formulation enables direct computation of the ART from the angular spectrum based beam shape coefficients ...

Effect of Acute Exercise on Pulmonary Function in Young Adults with Anaemia: A Quasi-experimental Study [PDF]
Journal of Clinical and Diagnostic ResearchIntroduction: Anaemia is a condition in which the Haemoglobin (Hb) level in the blood is below the reference range for age and gender. In India, mild anaemia is commonly found among medical students. Exercise capacity is limited by the ability to deliver

Influence of Slow-Paced Breathing on Inhibition After Physical Exertion
Frontiers in Psychology, 2019 This research aims to investigate whether slow-paced breathing (SPB) improves adaptation to psychological stress, and specifically inhibition, when it is performed before or after physical exertion (PE).

Radiation Reaction fields for an accelerated dipole for scalar and electromagnetic radiation [PDF]
, 1998 The radiation reaction fields are calculated for an accelerated changing dipole in scalar and electromagnetic radiation fields. The acceleration reaction is shown to alter the damping of a time varying dipole in the EM case, but not the scalar case. In the EM case, the dipole radiation reaction field can exert a force on an accelerated monopole charge ...

Load Carriage and Physical Exertion Influence Cognitive Control in Military Scenarios.
Medicine & Science in Sports & Exercise, 2019 INTRODUCTION Physical exertion has both beneficial and detrimental effects on cognitive performance, particularly cognitive control. Research into physical exertion under conditions of load carriage is particularly important given that military personnel

Direct and inverse spin Hall effect: Lorentz force and Zeeman energy [PDF]
, 2019 It is shown that magnetic forces as the Lorentz force, exerted on electric currents, and the force {\mu}Div(B), exerted on electron spins at rest, account for both the transverse spin imbalance typical of spin Hall effect and the transverse charge imbalance associated with pure spin currents (inverse spin Hall effect).
