Energy dissipation in turbulent reconnection [PDF]

Physics of Plasmas, 2021
We study the nature of pressure-strain interaction at reconnection sites detected by NASA's Magnetospheric Multiscale Mission. We employ data from a series of previously published case studies, including a large-scale reconnection event at the magnetopause, three small-scale reconnection events at the magnetosheath current sheets, and one example of ...

Calibration of an elastoplastic model of sand liquefaction using the swarm intelligence with a multi-objective function

Journal of Rock Mechanics and Geotechnical Engineering, 2023
According to post-seismic observations, spectacular examples of engineering failures can be ascribed to the occurrence of sand liquefaction, where a sandy soil stratum could undergo a transient loss of shear strength and even behave as a “liquid ...
