In general, a large percentage of the electric power produced is generated in huge generation centres far from the consumption, and with centralized transmission and distribution systems, where the weak point of this scheme is the efficiency with high energy losses in the form of heat. This problem has been increased in the last years due to the significant growth of electric energy demand and ...

Am J Physiol Heart Circ Physiol 304: H848–H860, 2013. First published January 11, 2013; doi:10.1152/ajpheart.00787.2012.—Bradycardia prolongs action potential (AP) durations (APD adaptation), enhances dispersion of repolarization (DOR), and promo...

smaller pieces of DNA via recombination, or as modula-opportunistic infections and malignancies in male homosexuals heralded the onset of the AIDS epidemic. The tors of gene expression through methylation of cis-acting transcriptional regulatory elements. Like some other subsequent identification of human immunodeficiency virus as the etiologic agent of AIDS led quickly to a infamous mucosal pa...

in the mam-malian cortex are often clustered into sub-millimeter-scale columns, which span the entire cortical plate (Mountcastle 1957; Hubel and Wiesel 1962). Although a direct relationship between this clustering and function is repeatedly questioned (Swindale 1990; Purves and others 1992; Horton and Adams 2005), the structure, function, and plasticity of cortical columns have no doubt been o...

multiple excavators producing multiple products of raw materials are highly complex and exhibit strong interdependencies between constituents. A network of conveyor belts is used for transportation of the extracted materials to different waste dumps or the coal stockpile. Optimal decision-making in short-term planning and production control are impacted mainly by geological uncertainty associat...

The bulk MOSFET scaling has recently encountered significant limitations, mainly related to the gate oxide (SiO2) leakage currents (Gusev et al., 2006; Taur et al., 1997), the large increase of parasitic short channel effects and the dramatic mobility reduction (Fischetti & Laux, 2001) due to highly doped Silicon substrates precisely used to reduce these short channel effects. Technological sol...

Acknowledgements We thank Dr. Clifton Ragsdale and Atul Mallik for helpful discussion. Abstract The organization of primary visual cortex has been heavily studied for nearly 50 years, and in the last 20 years functional imaging has provided high resolution maps of its tangential organization. Recently, however, the usefulness of maps like those of orientation and spatial frequency preference ha...

Anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV) is a severe condition encompassing two major syndromes – granulomatosis with polyangiitis (formerly known as Wegener’s--GPA) and microscopic polyangiitis (MPA). Its etiology is unknown, and whether it is a single disease entity, and the role of ANCA in its pathogenesis, are debated. To investigate the genetic basis of AAV a g...

Advances in technology are affecting every aspect of life in the 21st century, and dentistry is no exception. From diagnosis and treatment planning to all areas of dental treatment and global communications, technology is enhancing the level of patient care, practice efficiencies, and professional/patient education. In order to learn more about how a broad range of technologies can be implement...
