Since the 1997 H5N1 influenza virus outbreak in humans and poultry in Hong Kong, the emergence of closely related viruses in poultry has raised concerns that additional zoonotic transmissions of influenza viruses from poultry to humans may occur. In May 2001, an avian H5N1 influenza A virus was isolated from duck meat that had been imported to South Korea from China. Phylogenetic analysis of th...

Automatic Vehicle Location (AVL) and Automatic Passengers Counters (APC) systems have been increasingly implemented by transit agencies for the real time monitoring of transit vehicles and automatic counting of passengers boarding and alighting at bus stops. As a result, a vast amount of potentially online data related to transit operation could be obtained from these systems. The emphasis of t...

The idea of relaxed balance is to uncouple the rebalancing in search trees from the updating in order to speed up request processing in main-memory databases. In this paper, we describe a relaxed version of AVL trees. We prove that each update gives rise to at most a logarithmic number of rebalancing operations and that the number of rebalancing operations in the semidynamic case is amortized c...

In the New World, the leishmaniases are primarily transmitted to humans through the bites of Leishmania-infected Lutzomyia (Diptera: Psychodidae) phlebotomine sand flies. Any or both of two basic clinical forms of these diseases are endemic to several cities in Brazil--the American cutaneous leishmaniasis (ACL) and the American visceral leishmaniasis (AVL). The present study was conducted in th...

For a number of years vehicle fleet tracking systems are in use in companies operating large number of vehicles in the field. Proliferation of cheap and compact GPS receivers had the effect that Automatic Vehicle Location (AVL) systems today almost exclusively use satellite based locating systems. This paper presents characteristics of realized system tracking and analyzing city bus transit tra...

BACKGROUND Recent data suggest that Bruton's tyrosine kinase (BTK) is an emerging therapeutic target in IgE receptor (IgER)-cross-linked basophils. METHODS We examined the effects of four BTK inhibitors (ibrutinib, dasatinib, AVL-292, and CNX-774) on IgE-dependent activation and histamine release in blood basophils obtained from allergic patients (n=11) and nonallergic donors (n=5). In additi...

A study of the phlebotomine sand fly fauna was carried out in an endemic area of American visceral leishmaniasis (AVL) in the municipality of Porteirinha, in the Brazilian state of Minas Gerais. Captures were performed with CDC light traps in 7 districts, 5 days per month, during 2 consecutive years (January 2000 to December 2001). A total of 3240 sand flies were captured and identified. Sixtee...

Data structures are more easily understood when they are presented visually rather than textually. We have developed a system, Calypso, to allow the visual definition of data structures programs using pictorial pattern/action pairs in an imperative setting. We present several examples including rebalancing an AVL tree and sorting an array using the Quicksort algorithm. These examples demonstrat...

In past work we described a system of components that are used to construct transit traveler information applications. In this paper we describe an ongoing project that uses the same component architecture to combine maps, schedules, and AVL information from four transit agencies. The result is a set of web applications suitable for both transit management and traveler information. We describe ...
