Turbulent Kinetic Energy in the Energy Balance of a Solar Flare [PDF]
Physical Review Letters, 2017 The energy released in solar flares derives from a reconfiguration of magnetic fields to a lower energy state, and is manifested in several forms, including bulk kinetic energy of the coronal mass ejection, acceleration of electrons and ions, and enhanced thermal energy that is ultimately radiated away across the electromagnetic spectrum from optical ...

Can the Hartree–Fock kinetic energy exceed the exact kinetic energy?
The Journal of Chemical Physics, 2022 The Hartree–Fock (HF) approximation has been an important tool for quantum-chemical calculations since its earliest appearance in the late 1920s and remains the starting point of most single-reference methods in use today. Intuition suggests that the HF kinetic energy should not exceed the exact kinetic energy; but no proof of this conjecture exists ...

Applied Sciences, 2023 In the present work, we analyze the spatiotemporal dynamics of the kinetic wind energy with and without allowance for the kinetic energy of outliers. We first separated the contributions of the mean kinetic energy and the kinetic energy of the outliers ...

Energy Dissipation in Magnetic Islands Formed during Magnetic Reconnection
The Astrophysical Journal, 2023 Magnetic reconnection converts magnetic energy into particle kinetic energy, and satellite observations have shown that 20%–50% of magnetic energy is channeled into electron kinetic energy.

Rectilinear car motions taking into account the elasticity and deformability of tires [PDF]
E3S Web of Conferences, 2023 In this paper, the problem of developing a mathematical model of rectilinear motion of a car is solved, taking into account the elasticity and deformability of tires, as well as, for the same radii of the wheels of the car, and taking into account plane ...

A comparative study on the analysis of hemodynamics in the athlete’s heart
Scientific Reports, 2022 The pathophysiological mechanisms underlying the development of the athlete’s heart are still poorly understood. To characterize the intracavitary blood flows in the right ventricle (RV) and right-ventricular outflow tract (RVOT) in 2 healthy probands ...

Nonlinear chiral kinetic theory [PDF]
, 2023 From quantum field theory, we derive the chiral kinetic theory involving nonlinear quantum corrections coupled with spacetime-dependent electromagnetic fields and fluid velocity gradients. An equilibrium Wigner function determined by the kinetic equation verifies the nondissipativeness of the charge induced by the magneto-vortical coupling.
