DOI: 10.1002/jemt.24111

Abstract: Literature reports indicate that during bracket removal there can be enamel damage. We compare the shear bond strength (SBS) and tooth enamel loss of four adhesive systems and identify the Ca/P ratio. Then a total… read more here.

DOI: 10.1007/jhep09(2021)083

Abstract: Abstract We develop the covariant phase space formalism allowing for non-vanishing flux, anomalies, and field dependence in the vector field generators. We construct a charge bracket that generalizes the one introduced by Barnich and Troessaert… read more here.

DOI: 10.1016/j.forsciint.2020.110182

Abstract: In cases of incineration, where the identification of victims by conventional methods is impossible, teeth and dental materials become an available source of evidence - thanks to their ability to resist high temperatures. Currently, there… read more here.

DOI: 10.1016/j.geomphys.2020.103812

Abstract: A variational formulation for nonequilibrium thermodynamics was recently proposed in [7, 8] for both discrete and continuum systems. This formulation extends the Hamilton principle of classical mechanics to include irreversible processes. In this paper, we… read more here.

DOI: 10.1063/5.0180407

Abstract: We examine quantitatively the role of dissipation in nonequilibrium thermodynamics and its connection to variational principles and the Rayleighian functional. The extremum of the Rayleighian is sometimes used to describe the inertialess (dissipation-dominated) dynamics of… read more here.

DOI: 10.1063/5.0287907

Abstract: The metriplectic formulation of collisional guiding-center Vlasov–Maxwell–Landau theory is presented. The guiding-center Landau collision operator, which describes collisions involving test-particle and field-particle guiding-center orbits, is represented in terms of a symmetric dissipative bracket involving functional… read more here.
