Singular extremals for the time-optimal control of dissipative spin 1/2 particles
, 2010 We consider the time-optimal control by magnetic fields of a spin 1/2 particle in a dissipative environment. This system is used as an illustrative example to show the role of singular extremals in the control of quantum systems. We analyze a simple case

Methods in Ecology and Evolution, Volume 17, Issue 1, Page 137-157, January 2026.Abstract Lifetime reproductive success (LRS) is a key metric in ecology and evolution. It measures the number of offspring produced by an individual during its lifetime. In epidemiology, it corresponds to the number of secondary cases generated by an infected individual.

Annales de Didactique et de Sciences Cognitives, 2015 It seems obvious that teacher educators should themselves be trained. Nevertheless, rare are research studies that consider this issue. In this paper we trace the history and present the theoretical background of a university program for training ...

On the concept of (homo)morphism : a key notion in the learning of abstract algebra
, 2013 This article is dedicated to the investigation of difficulties involved in the understanding of the homomorphism concept. It doesn't restrict to group-theory but on the contrary raises the issue of developing teaching strategies aiming at gaining access ...
