Jean-charles Faugère Chapitre 1 Introduction Générale

We present an efficient algorithm for the transformation of a Gröbner basis of a zero–dimensional ideal with respect to any given ordering into a Gröbner basis with respect to any other ordering. This algorithm is polynomial in the degree of the ideal. In particular the lexicographical Gröbner basis can be obtained by applying this algorithm after a total degree Gröbner basis computation: it is...

Charles Darwin: the man and his influence

One of the most exciting parts of neuroscience is the rapidly growing field of developmental neurobiology. As in all scientific enterprises today, the increasing volume of literature means that most participants are content to peruse only material of the last two or three decades. However, in this particular area of research ideas and experimental data reported almost eighty years ago are of re...

A general model of problem-solving processes based on misconception elimination is presented to simulate both impasses and solving processes. The model operates an goal-related rules ond a set of constraint rules in the farm of “IF (state or goal), DO NOT (Action)” for the explicit constraints in the instructions and the implicit constraints that come from misconceptions of legal moves. When im...

Jean-Martin Charcot and his vibratory chair for Parkinson disease.

Vibration therapy is currently used in diverse medical specialties ranging from orthopedics to urology to sports medicine. The celebrated 19th-century neurologist, J.-M. Charcot, used vibratory therapy to treat Parkinson disease (PD). This study analyzed printed writings by Charcot and other writers on vibratory therapy and accessed unpublished notes from the Salpêtrière Hospital, Paris. Charco...
