Quasisaddles as relevant points of the potential energy surface in the dynamics of supercooled liquids [PDF]

open access: yesThe Journal of Chemical Physics, 2002
The supercooled dynamics of a Lennard-Jones model liquid is numerically investigated studying relevant points of the potential energy surface, i.e., the minima of the square gradient of total potential energy V. The main findings are (i) the number of negative curvatures n of these sampled points appears to extrapolate to zero at the mode coupling ...

Wintertime tales: How the lizard Liolaemus lineomaculatus endures the temperate cold climate of Patagonia, Argentina

open access: yesAnais da Academia Brasileira de Ciências, 2022
In temperate, polar and montane environments, ectotherms must find ways to endure throughout the coldest months of the year. Lizards search for microsites where temperatures remain warm or alter their biochemical balance to tolerate freezing or avoid it ...
