Traffic accident forecasting is of great importance to urban public safety, emergency treatment, and construction planning. However, it very challenging since traffic accidents are affected by multiple factors, have multi-scale dependencies on both spatial temporal dimensional features. Meanwhile, rare events, which leads the zero-inflated issue. Existing methods cannot deal with all above prob...

background : cockroaches are of vital importance medically and hygienically. they are able to contaminate foods and act as vectors of pathogenic agents such as bacteria, protozoa, and parasites to human environment either mechanically or through their digestive system. cockroaches belong to the phylum arthropoda, class insecta, and order blattodea or blattaria. to date, over 4,500 cockroach spe...

A number of studies have examined the benefits of regional diversification strategies within commercial real estate portfolios with two approaches adopted; the first is based on primary contiguous geographical regions while the second employs areas based on economic function. In general, the conclusion is that diversifications strategies based on simple geographical areas adds little, if anythi...

France is in the process of reorganizing its regions. We propose a heuristic search algorithm that optimizes french regions using geographical, economical and political heuristics. The corresponding admissible heuristics are explained and integrated into the search algorithm.

In this work we investigate the betweenness centrality in geographical networks and its relationship with network communities. We show that vertices with large betweenness define what we call characteristic betweenness paths in both modeled and real-world geographical networks. We define a geographical network model that possess a simple topology while still being able to present such betweenne...

Geographic Proximity, Trade and International Conflict/Cooperation This paper examines the interactive effect of distance and trade on international conflict and cooperation. The effect of geographic distance depends on trade, while the effect of trade varies with geographic distance. Trade reduces conflict to a greater extent when dyads are geographically close, but has a greater effect on coo...

In this study, a battery of oligonucleotides was directed toward the katG gene and PCR-single-stranded conformation polymorphism (SSCP) analysis was used to search for katG gene deviations in clinical isolates of Mycobacterium tuberculosis from different geographical regions. Since a complete deletion of the katG gene was not found, it is suggested that deletion is not a major mechanism of ison...
