For most living beings, oxygen is an essential molecule for survival, being the basis of biological oxidations, which satisfy energy needs aerobic organisms. Oxygen can also behave as a toxic agent posing threat to existence beings since it give rise reactive species (ROS) that oxidise macromolecules, among proteins and lipids are preferred targets. Oxidative damage induce cell, tissue, organ d...

This article deals with ambiguous surface digitizations by dilation in n-dimensional space. The digitization of a sufficiently regular surface is separating but not necessarily minimal. We will determine conditions under which the supercover and the grid intersection digitizations are discrete surfaces. It will also be proven that non-overlapping domains do not solve the problem of simple point...
