Hydrodynamics plays a major role in transport of heat and mass transfer microchannels. This includes flow patterns regimes which the micro-channels are operated. The have impact properties. Another important aspect is pressure drop micro-channels. In present review, experimental Computational Fluid Dynamics (CFD) studies covering all above aspects been covered. effect geometrical parameters lik...

The performance of proton-exchange membrane fuel cell cooling system using coolant flow channels enhanced with baffles was numerically investigated. To do this, the maximum temperature of the cooling plate, temperature uniformity and also pressure drop along the flow channels were compared for different cases associated with number of baffles and their dimensions inside the channels. The govern...

The spatial and temporal scales of cardiac organogenesis and pathogenesis make engineering of artificial heart tissue a daunting challenge. The temporal scales range from nanosecond conformational changes responsible for ion channel opening to fibrillation which occurs over seconds and can lead to death. Spatial scales range from nanometre pore sizes in membrane channels and gap junctions to th...

INtrODUctION Humans have learned to cooperate in many ways and in many environments, on different tasks, and for achieving different and several goals. Collaboration and cooperation in their more general sense (and, in particular, negotiation, exchange, help, delegation, adoption, and so on) are important characteristics-or better, the most foundational aspects-of human societies (Tuomela, 1995...

This paper presents a self-supervised algorithm for learning perceptual structures based upon correlations in different sensory modalities. The brain and cognitive sciences have gathered an enormous body of neurological and phenomenological evidence in the past half century that demonstrates the extraordinary degree of interaction between sensory modalities during the course of ordinary percept...

The vacuolating toxin VacA, a major determinant of Helicobacter pylori-associated gastric diseases, forms anion-selective channels in artificial planar lipid bilayers. Here we show that VacA increases the anion permeability of the HeLa cell plasma membrane and determines membrane depolarization. Electrophysiological and pharmacological approaches indicated that this effect is due to the formati...
