La production d’une baladodiffusion éducative en obstétrique et gynécologie

Implication Statement: Podcasts are used in medical education to supplement conventional teaching methods such as lectures and reading. We identified a lack of Canadian medical education podcasts covering obstetrics and gynecology (Ob/Gyn) content and created a podcast specific for Canadian medical students and residents. The podcast called “OB-G in YEG” is freely available and currently has fourteen episodes that cover common topics in Ob/Gyn. We describe the process for creating a high-quality medical education resource that is widely accessible to learners that readers may be able to replicate in their own discipline.Énoncé des implications de la recherche Les baladodiffusions sont utilisées dans l’éducation médicale en complément aux méthodes d’enseignement traditionnelles comme les cours magistraux et la lecture de textes. Ayant constaté un manque de baladodiffusions d'enseignement dans les domaines de l’obstétrique et de la gynécologie (OB/GY) au Canada, nous avons créé une telle émission destinée aux étudiants et aux résidents en médecine de ce pays. La baladodiffusion, intitulée « OB-G in YEG », est disponible gratuitement et elle comporte actuellement onze épisodes sur des sujets d’intérêt général touchant à l’obstétrique et à la gynécologie. Nous décrivons le processus de création d'une ressource d'enseignement médical de qualité, qui est largement accessible aux apprenants et que les lecteurs seraient peut-être en mesure de reproduire dans leur propre discipline

Analytic Loops and Gauge Fields

In this paper the linear representations of analytic Moufang loops are investigated. We prove that every representation of semisimple analytic Moufang loop is completely reducible and find all nonassociative irreducible representations. We show that such representations are closely associated with the (anti-)self-dual Yang-Mills equations in ${\bf R}^8$Comment: 10 pages, LaTeX, no figure

Vibrational energy relaxation in proteins

An overview of theories related to vibrational energy relaxation (VER) in proteins is presented. VER of a selected mode in cytochrome c is studied using two theoretical approaches. One is the equilibrium simulation approach with quantum correction factors, and the other is the reduced model approach which describes the protein as an ensemble of normal modes interacting through nonlinear coupling elements. Both methods result in estimates of the VER time (sub ps) for a CD stretching mode in the protein at room temperature. The theoretical predictions are in accord with the experimental data of Romesberg's group. A perspective on future directions for the detailed study of time scales and mechanisms for VER in proteins is presented.Comment: 12 pages, 4 figures, accepted for publication in PNA

Duality between a deterministic cellular automaton and a bosonic quantum field theory in 1+1 dimensions

Methods developed in a previous paper are employed to define an exact correspondence between the states of a deterministic cellular automaton in 1+1 dimensions and those of a bosonic quantum field theory. The result may be used to argue that quantum field theories may be much closer related to deterministic automata than what is usually thought possible. Version 2 had a minor typo corrected and notation was made more consistent.Comment: 18 pages (incl. Title page). No figure

The Seven-sphere and its Kac-Moody Algebra

We investigate the seven-sphere as a group-like manifold and its extension to a Kac-Moody-like algebra. Covariance properties and tensorial composition of spinors under $S^7$ are defined. The relation to Malcev algebras is established. The consequences for octonionic projective spaces are examined. Current algebras are formulated and their anomalies are derived, and shown to be unique (even regarding numerical coefficients) up to redefinitions of the currents. Nilpotency of the BRST operator is consistent with one particular expression in the class of (field-dependent) anomalies. A Sugawara construction is given.Comment: 22 pages.

Derivations and automorphisms of free nilpotent Lie algebras and their quotiens

Let \n_{d,t} be the free nilpotent Lie algebra of type $d$ and nilindex $t$. Starting out with the derivation algebra and the automorphism group of \n_{d,t}, we get a natural description of derivations and automorphisms of any generic nilpotent Lie algebra of the same type and nilindex. Moreover, along the paper we discuss several examples to illustrate the obtained results.Comment: 13 page
