Significant unprotected left main coronary artery (ULMCA) disease occurs in 5-7% of patients undergoing coronary angiography [1,2] and patients with ULMCA disease treated medically have a three years mortality rate of 50% [3,4]. Advances in percutaneous intervention techniques and stent technology have allowed evolution of the role of percutaneous coronary intervention (PCI) for left main disea...

Behavioral studies have shown that spatial skills, such as mental rotation, are correlated with preferences for certain types of spatial information. To be more specific, better mental rotation is associated with a preference for survey (maplike) spatial information relative to route (landmark or wayfinding) information. Functional MRI was used to investigate how individual differences in spati...

A common behavioral assumption in the study of transportation and telecommunication networks is that travelers or packets, respectively, choose routes that they perceive as being the shortest under the prevailing traffic conditions [1]. The situation resulting from these individual decisions is one in which drivers cannot reduce their journey times by unilaterally choosing another route, which ...

The aim of this study was to investigate whether intradermal (ID) vaccination against foot-andmouth disease (FMD) is suitable as an alternative for the usually used intramuscular (IM) route. We used vaccines containing a normal or 10-fold dose antigen and compared groups of pigs that were vaccinated ID with either 0.2ml or 4x0.2ml with groups of pigs that were vaccinated IM with a standard 2ml,...

Ubiquitous and mobile computing has become an important field in computer science. The provision, management and transmission of information within computer systems and for human-computer interaction is required for many applications and the individual needs of the mobile user are manifold. Due to information overflow it is difficult for the user to access specific pieces of information while k...

In order to shorten the development time, it is important that resources in development be focused on doing things “Right the First Time”. The cost of making a chemical compound that potentially has very attractive properties might be prohibitively high and finding a feasible alternative route quickly is imperative. History shows that even very promising drugs don’t make to market because of th...

At Asiacrypt’99, Vaudenay modified the structure in the IDEA cipher to a new scheme, which they called as the Lai-Massey scheme. It is proved that 3-round Lai-Massey scheme is sufficient for pseudorandomness and 4-round Lai-Massey scheme is sufficient for strong pseudorandomness. But the author didn’t point out whether three rounds and four rounds are necessary for the pseudorandomness and stro...

Contention based MAC protocols like IEEE 802.11 have been shown to perform badly in multi-hop wireless ad hoc networks [1]. Immediate alternative approaches are contention-free MAC protocols such as fixed TDMA and CDMA. The Bluetooth scatternet structure, integrating polling scheme and FHSS in its MAC layer, provides a contention-free environment for Bluetooth devices to access the medium and c...

Travel time data becomes widely available with the deployments of location-based technologies including GPS-equipped vehicles and cell phones, Bluetooth readers, Dedicated Short Range Communication devices, etc. This change has made a shift on the existing distance or historical speed based route guidance to travel time-based route guidance. For example, commercial GP-based navigation system ut...
