Analysis of fragment yield ratios in the nuclear phase transition [PDF]

open access: yes, 2010
The critical phenomena of the liquid-gas phase transition has been investigated in the reactions 78,86Kr+58,64Ni at beam energy of 35 MeV/nucleon using the Landau free energy approach with isospin asymmetry as an order parameter.

Braking--Radiation: An Energy Source for a Relativistic Fireball [PDF]

open access: yes, 2000
If the Schwarzschild black-hole is moving rectilinearly with uniform 3-velocity and suddenly stops, according to a distant observer, then we demonstrate that this observer will see a spherical light--like shell or "relativistic fireball" radiate outwards

A New Technology Applied to Power System Stability Control: Phase Sequence Exchange Technology

open access: yesIEEE Access, 2019
AC transmission systems are often affected by stability issues. During the design phase of such systems, their ability to cope with the various kinds of disturbance is taken into consideration, however, sudden large disturbances may still result in power
