Numerical investigation of bubbles coalescence in a shear flow with diffuse-interface model

open access: yesHeliyon, 2018
In this article, we apply the diffuse-interface model [developed by Shah and Yuan (2011) [21]] for collision and coalescence of two bubbles in a linear shear flow.

Pincherle's theorem in Reverse Mathematics and computability theory

open access: yes, 2020
We study the logical and computational properties of basic theorems of uncountable mathematics, in particular Pincherle's theorem, published in 1882. This theorem states that a locally bounded function is bounded on certain domains, i.e. one of the first

Habituation as optimal filtering

open access: yesiScience
Summary: Habituation, the reduction of responding to repetitive stimuli, is often conceptualized as a kind of attentional filter, amplifying salient signals at the expense of non-salient signals.
