The Writing Committee conducted a comprehensive search of the medical literature concerning cocaine-associated chest pain and MI. The literature search included English-language publications on humans and animals from 1960 to 2007. In addition to broad-based searching concerning cocaine, specific targeted searches were performed on cocaine and the following topics: MI, chest pain, emergency dep...

Power transformers are the most important assets in substations and play an important role in the reliability of electrical systems and in the quality of the energy delivered. As the population of transformers in service is getting old, much attention must be focused on transformers availability and reliability. So the condition and risk assessment of the transformers are more and more importan...

Communities of practice (CoPs) play a critical role in delivery and sharing of knowledge. Apart from the easy expression of explicitly knowledge, the dynamic processes and complex interactions in online CoPs do mediate the creation and transfer of tacit knowledge as well. This is inferred from the many ways CoPs have revolutionalized the ways in which context-specific knowledge is shared virtua...

Rudolf Virchow, the renowned father of Modern Pathology, is credited with many monumental medical findings that continue to pervade the realms of modern medicine. His numerous discoveries notwithstanding, Virchow is remarkable in that he is attributed a theory on the complex pathogenesis of venous thrombosis – in an age limited by a rudimentary understanding of pathobiology and crude experiment...

Volume 3 | Issue 1 Abstract Cephalofacial measurements and indices are used to estimate sex and race. The aim of this is to document the craniofacial characteristics and sex differences from cephalic index and facial index of the studied groups. Maximum head length, maximum head width, morphological facial length and morphological facial width were determined for 901 Gujarati (676 male, 225 fem...

Between 1999 and 2006, there were two episodes during which inflation in the Rent index in the CPI diverged markedly from inflation in the index for Owner’s Equivalent Rent (OER); early in 2007, these series began to diverge again. Such divergence often prompts many to question CPI methods. A key difference between these two series is that OER indexes are based upon rents which have received a ...

The pan-European MacroBen database was used to compare the AZTI Marine Biotic Index (AMBI) and the Benthic Quality Index (BQIES), 2 biotic indices which rely on 2 distinct assessments of species sensitivity/tolerance (i.e. AMBI EG and BQI E[S50]0.05) and which up to now have only been compared on restricted data sets. A total of 12 409 stations were selected from the database. This subset (indi...

Many feature selection and feature ranking methods have been proposed. Using real and artificial data an attempt has been made to compare some of these methods. The "feature relevance index" used seems to have little effect on the relative ranking. For continuous features discretization and kernel smoothing are compared. Selection of subsets of features using hashing techniques is compared with...
