In functional genomics, the high-throughput methods such as microarrays 1) allow analysis of the relationships between genes considering them as elements of a network and 2) lead to biological interpretations thanks to Gene Ontology. But up to now it has not been possible to find relationships between the functions and the connectivity of the genes in coexpression networks. To achieve this aim,...

We examine two factors that might explain the extent of air traffic delays in the United States: network benefits due to hubbing and congestion externalities. Airline hubs enable passengers to cross-connect to many destinations, thus creating network benefits that increase in the number of markets served from the hub. Delays are the equilibrium outcome of a hub airline equating high marginal be...

8001 Natural Bridge Road St. Louis, Missouri 63121-4499 Most American municipalities that incorporated prior to 1930, regardless of population size or geographic region, contain a downtown district. These traditional downtowns usually constituted the community’s retail hub, featured a highdensity walkable setting, and were at the center of community and civic life. The decades following World W...

Vortrag zur TAV31) Dipl.-Math. Hermann Will www.qadvice.de Februar 2011 Der Trend zur Konzentration von Applikationen und IT-Equipment in immer weniger Rechenzentren hat durch das Cloud-Computing einen weiteren Schub erhalten. Mega-Rechenzentren mit mehreren 10.000 m Fläche sind heute keine Seltenheit mehr. Hohe Verfügbarkeitsanforderungen und die Vielfalt an Nutzungsszenarien und interagierend...

This paper presents a novel Time Difference of Arrival (TDoA) estimation algorithm for mobile station positioning in Universal Mobile Telecommunication System (UMTS) based on cell search procedure defined by 3GPP. Standardized method for Time Difference of Arrival (TDoA) measurement and cell search procedure are stated. Furthermore, proposed solution for TDoA parameter estimation via multichann...

We consider the problem of recovering the graph structure of a “hub-networked” Ising model given i.i.d. samples, under high-dimensional settings, where number of nodes p could be potentially larger than the number of samples n. By a “hub-networked” graph, we mean a graph with a few “hub nodes” with very large degrees. State of the art estimators for Ising models have a sample complexity that sc...

Introduction Emilia Romagna is a region caracterized by the presence of Three Integrated Trauma Systems Care (ITSC). Severe, resource-consuming patients are centralized in first level Hubs to guarantee high quality and efficient care. Every ITSC has a Trauma Center (Hub) connected with a net of peripheral hospitals (Spokes). A Helicopter Emergency Medical Service (HEMS) has been active since Ju...

BACKGROUND Current WHO best infection control practices for injections do not address the use of hub cutters due to insufficient evidence on safety and efficacy. OBJECTIVE To assess the impact of the use of hub cutters on 1) the frequency of needle-stick injuries (NSIs) and other blood exposures among workers and 2) the volume of sharps waste in a mass vaccination campaign setting. METHODS ...

Energy efficiency is becoming increasingly important in the operation of networking infrastructure, especially in enterprise and data center networks. Researchers have proposed several strategies for energy management of networking devices. However, we need a comprehensive characterization of power consumption by a variety of switches and routers to accurately quantify the savings from the vari...
