Enhancement of superconductivity due to kinetic-energy effect in the strongly correlated phase of the two-dimensional Hubbard model [PDF]
Physics Letters A 403 (2021) 127382, 2021 We investigated kinetic properties of correlated pairing states in strongly correlated phase of the Hubbard model in two space dimensions. We employ an optimization variational Monte Carlo method, where we use the improved wave function $\psi_{\lambda}= e^{-\lambda K}\psi_G$ for the Gutzwiller wave function $\psi_G$ with $K$ being the kinetic part of ...

Frontiers in Cardiovascular Medicine, 2021 Introduction: Seismocardiography (SCG) records cardiac and blood-induced motions transmitted to the chest surface as vibratory phenomena. Evidences demonstrate that acute myocardial ischemia (AMI) profoundly affects the SCG signals.

Energy partition for anharmonic, undamped, classical oscillators [PDF]
J. Phys. A: Math. Theor. 53, 195001 (2020), 2020 Using stochastic methods, general formulas for average kinetic and potential energies for anharmonic, undamped (frictionless), classical oscillators are derived. It is demonstrated that for potentials of $|x|^\nu$ ($\nu>0$) type energies are equipartitioned for the harmonic potential only.

Kinetic energy and the equivalence principle [PDF]
American Journal of Physics, 1998 According to the general theory of relativity, kinetic energy contributes to gravitational mass. Surprisingly, the observational evidence for this prediction does not seem to be discussed in the literature. I reanalyze existing experimental data to test the equivalence principle for the kinetic energy of atomic electrons, and show that fairly strong ...

A new dynamic subgrid-scale model using artificial neural network for compressible flow
Theoretical and Applied Mechanics Letters, 2022 The subgrid-scale (SGS) kinetic energy has been used to predict the SGS stress in compressible flow and it was resolved through the SGS kinetic energy transport equation in past studies.

Analysis of the kinetic energy from fission fragments using dynamical model [PDF]
EPJ Web of ConferencesIt is known that the kinetic energy of individual fragments for fission of actinides is constant at about 100 MeV for light fragments and that for heavy fragments decreases with mass number.

Nonlinear Kinetic Energy Harvesting
Procedia Computer Science, 2011 AbstractHarvesting of kinetic energy present in the form of random vibrations is an interesting option due to the almost universal presence of this kind of motion. Traditional generators based on piezoelectric effect are built with linear oscillators made by a piezoelectric beam and a mass used to tune the resonance frequency on the predominant ...

Turbulent drag reduction in magnetohydrodynamic and quasi-static magnetohydrodynamic turbulence
, 2020 In hydrodynamic turbulence, the kinetic energy injected at large scales cascades to the inertial range, leading to a constant kinetic energy flux. In contrast, in magnetohydrodynamic (MHD) turbulence, a fraction of kinetic energy is transferred to the ...
