Gradient flows as a selection procedure for equilibria of nonconvex energies [PDF]

open access: yes, 2006
For atomistic material models, global minimization gives the wrong qualitative behavior; a theory of equilibrium solutions needs to be defined in different terms.

Childhood conscientiousness predicts the social gradient of smoking in adulthood: a life course analysis. [PDF]

open access: yes, 2015
The social gradient in smoking is well known, with higher rates among those in less advantaged socioeconomic position. Some recent research has reported that personality characteristics partly explain this gradient. However, the majority of existing work

Tunable phase-gradient-based optical tweezers

open access: yes, 2019
Conventional optical tweezers are generated by the intensity gradient of highly focused laser beams, but the requirement of strong intensity gradient limits the tunability of optical traps.

Materials in thermodynamic potential gradients [PDF]

open access: yesPure and Applied Chemistry, 2003
Abstract In materials that are exposed to thermodynamic potential gradients (i.e., gradients of chemical potentials, electrical potential, temperature, or pressure), transport processes of the mobile components occur. These transport processes and the coupling between different processes are not only of fundamental interest, but are also
