Hommage à Xavier Bonnet

Charles Bonnet, Lettres à M. l'Abbé Spallanzani

when Davis et al. in 1962, demonstrated the breakdown of ATP in a single tetanic contraction of a muscle treated with l-fluoro-2, 4-dinitrobenzene. Chapter 15 is devoted to rigor mortis. Preceded by chapters on the general history of respiration (Chapter 16) and of oxidative phosphorylation (Chapter 17), Chapter 18 is concerned with the regulation of carbohydrate metabolism for energy supply to...

Hommage to reactive psychosis.

When looking back in the history of psychiatry, the concept of reactivity had very variable impact on ethiological considerations. If classification of mental disorders is taken as a proxy, it seems that this impact is presently at the lowest that it has been in the last hundred years. The author gives a short historical overview of concept of reactive psychosis, followed by a description of th...

The analysis shows that the configurational space contains only three dense sub-states. These states of relatively low tree energy corre...

Lessons learned from Xavier

Mathematical Logic Xavier

In any model theoretic logic, Beth’s definability property together with Feferman-Vaught’s uniform reduction property for pairs imply recursive compactness, and the existence of models with infinitely many automorphisms for sentences having infinite models. The stronger Craig’s interpolation property plus the uniform reduction property for pairs yield a recursive version of Ehrenfeucht-Mostowsk...
