We read the study by Borjigin et al. about postcardiac arrest electrical activity and the possible explanation for near death experiences (NDEs) with great interest (1). Our research group at The George Washington University Medical Center published an observation of end-of-life electrical surges (ELES) in 2009 (2). In that study, we proposed that ELES could be responsible for NDEs, and this ne...

We present in this report two modelizations of vibrational relaxation processes in a gaz: the Landau-Teller (LT) model and the master equations (ME). We give diierent models for VT and VV rate constants. We propose an algorithm to solve the equations of vibrational relaxation (LT or ME) coupled with conservation equations of momentum and total energy. Both models are compared on the computation...

Architecturesparalì eles, bases de données, réseaux et systèmes distribués Abstract: We present a model for a library of synchronous VLSI components, which describes both their function and their timing diagrams, without describing the internal implementation of the circuit. Our model is based on Synchronous Data Flow, with extentions to model VLSI circuits, and to verify that a system designed...

This paper presents an environment for programming distributed memory computers using a language such as High Performance Fortran. Emphasis is put on compilation techniques for parallel loops and on the associated runtime support. A multi-threads scheme has been deened and implemented in order to eeciently overlap the communication and the computation phases. Un ex ecutif utilisant les processu...

A method for fault detection is proposed using nonlinear black-box models, such as polynomial regression and neural networks. Compared to existing methods, this proposed method has the advantage of not requiring model training under all the possible faulty modes of the monitored system. Partial physical knowledge , if available, can be combined with the nonlinear black-box model to perform faul...

Injured or ischemic cardiac tissue has limited intrinsic capacity for regeneration. While stem cell transplantation is a promising approach to stimulating cardiac repair, its success in humans has thus far been limited. Harnessing the therapeutic benefits of stem cells requires a better understanding of their mechanisms of action and methods to optimize their function. Cardiac stem cells (CSC) ...
