facilitate coordinated working, choosing to concentrate only on those techniques that have received the support of computing devices, broadly speaking, and that have transformed themselves into technologies, in however primitive a fashion. WET ICE has had to also steer clear of extensive fields such as distributed computing, client-server databases, and multimedia, which are all served by sever...

The growing adoption of 802.11 networks in the enterprise segment has led to the emergence of High Density (HD) WLAN scenarios where large (100-1000) numbers of clients are serviced by 10100s of APs in a multi-cell environment. This leads to an interference limited environment due to limited spectrum availability; hence network design for throughput scalability becomes the primary design challe...

Theories about the evolution of consciousness relate in an intimate way to theories about the distribution of consciousness, which range from the view that only human beings are conscious to the view that all matter is in some sense conscious. Broadly speaking, such theories can be classified into discontinuity theories and continuity theories. Discontinuity theories propose that consciousness ...

SENPs are proteases that participate in the regulation of SUMOylation by generating mature small ubiquitin-related modifiers (SUMO) for protein conjugation (endopeptidase activity) and removing conjugated SUMO from targets (isopeptidase activity). Using purified recombinant catalytic domains of 6 of the 7 human SENPs, we demonstrate the specificity of their respective activities on SUMO-1, -2, ...

Atrial tachycardia (AT) may be encountered in a variety of settings in the electrophysiology laboratory. It constitutes a differential diagnosis in patients presenting for an electrophysiological evaluation and ablation for paroxysmal supraventricular tachycardia. These patients typically do not have any evidence of structural heart disease. Patients may also present with AT in setting of an at...

Relativistic shocks accelerate particles by the first order Fermi mechanism. These particles then emit synchrotron emission in the post shock gas. We have developed a numerical code which integrates the relativistic Euler equations for fluid dynamics with a general equation of state, together with the Liouville equation for the accelerated particles. We present tests of this code and, in additi...

PURPOSE This study describes the typical case of problem-based learning (PBL) application at the Faculty of Medicine of the Université de Montréal and its analysis from the perspective of situated cognition. METHOD I used a typical case study to determine the general model of PBL application and performed my analysis by a global processing of information, against to the conceptual model of si...

The prefrontal cortex subserves executive control, i.e. the ability to select actions and to organize behavior in relation to internal drives and subjective preferences, ranging from the simplest behaviors, like choosing an apple or a pear in a fruit basket, to the most complex ones like deciding the next move in a game of chess. Whether simple or complex, decisions to act emerge from the combi...

John Dilworth How can it be true that one sees a lake when looking at a picture of a lake, since one's gaze is directed upon a flat dry surface covered in paint? An adequate contemporary explanation cannot avoid taking a theoretical stand on some fundamental cognitive science issues concerning the nature of perception, of pictorial content, and of perceptual reference to items that, strictly sp...

Broadly speaking, machine learning programs are asked to identify a single concept given a set of examples and some background knowledge. Mathematical theory formation programs, such as the AM program, (Davis & Lenat 1982) and the HR program, (Colton, Bundy, & Walsh 1999), are also given a set of examples and some background knowledge. However, they are not asked to find a single concept, but r...
