Accuracy in the experimental calorimetric study of the crystallization kinetics and predicitve transformation diagrams: Application to a Ga-Te amorphous alloy

The uncertainties inherent to experimental differential scanning calorimetric data are evaluated. A new procedure is developed to perform the kinetic analysis of continuous heating calorimetric data when the heat capacity of the sample changes during the crystallization. The accuracy of isothermal calorimetric data is analyzed in terms of the peak-to-peak noise of the calorimetric signal and base line drift typical of differential scanning calorimetry equipment. Their influence in the evaluation of the kinetic parameters is discussed. An empirical construction of the time-temperature and temperature heating rate transformation diagrams, grounded on the kinetic parameters, is presented. The method is applied to the kinetic study of the primary crystallization of Te in an amorphous alloy of nominal composition Ga20Te80, obtained by rapid solidification.

Perturbation theory for classical thermodynamic Green's functions

A systematic time-dependent perturbation scheme for classical canonical systems is developed based on a Wick's theorem for thermal averages of time-ordered products. The occurrence of the derivatives with respect to the canonical variables noted by Martin, Siggia, and Rose implies that two types of Green's functions have to be considered, the propagator and the response function. The diagrams resulting from Wick's theorem are "double graphs" analogous to those introduced by Dyson and also by Kawasaki, in which the response-function lines form a "tree structure" completed by propagator lines. The implication of a fluctuation-dissipation theorem on the self-energies is analyzed and compared with recent results by Deker and Haake.

Sleeping Beauty in Chelmno: Jane Yolen's Briar Rose or Breaking the Spell of Silence

AbstractThis article analyses Jane Yolen's Briar Rose (1992) from the perspective of trauma studies as a novelistic transposition of "Sleeping Beauty" in the context of the Holocaust. It argues that the fairy tale fulfils a psychological and even existential role for the fictional survivor of the extermination camp, but also a pedagogical, moral and political one through the figure of the cowitness central to the economy of the novel. Through Becca's recovery of the biographical elements underlying her grandmother's retelling of the story, Yolen shows how the fairy tale can serve to communicate traumatic personal memories and transmit collective cultural knowledge to counter the disappearance of first-hand witnesses.RésuméCet article analyse le recours au conte de fées dans un roman récent de Jane Yolen, Briar Rose, qui transpose le conte de La Belle au bois dormant dans le contexte de l'Holocauste. A partir des études sur le traumatisme (trauma studies), il montre comment le conte de fées remplit plusieurs rôles: psychologique voire existentiel pour la survivante du camp, mais aussi didactique, politique et moral à travers la figure du co-témoin placée au coeur du dispositif narratif. Yolen fait ainsi appel à deux genres pédagogiques, le conte et la literature de jeunesse sur l'Holocauste comme outils pédagogiques permettant la transmission d'une mémoire individuelle et collective qui problématise la question épineuse de la représentation de l'Holocauste et de la fictionnalisation de l'histoire qui accompagne la disparition des témoins directs.

Observation of a continuous interior crisis in the Hindmarsh-Rose neuron model.

Interior crises are understood as discontinuous changes of the size of a chaotic attractor that occur when an unstable periodic orbit collides with the chaotic attractor. We present here numerical evidence and theoretical reasoning which prove the existence of a chaos-chaos transition in which the change of the attractor size is sudden but continuous. This occurs in the Hindmarsh¿Rose model of a neuron, at the transition point between the bursting and spiking dynamics, which are two different dynamic behaviors that this system is able to present. Moreover, besides the change in attractor size, other significant properties of the system undergoing the transitions do change in a relevant qualitative way. The mechanism for such transition is understood in terms of a simple one-dimensional map whose dynamics undergoes a crossover between two different universal behaviors
