The increasing availability of large-scale trajectory data provides us great opportunity to explore them for knowledge discovery in transportation systems using advanced data mining techniques. Nowadays, large number of taxicabs in major metropolitan cities are equipped with a GPS device. Since taxis are on the road nearly twenty four hours a day (with drivers changing shifts), they can now act...

PURPOSE The aims of the present study were to investigate (i) the changes in participation and performance and (ii) the gender difference in Triple Iron ultra-triathlon (11.4 km swimming, 540 km cycling and 126.6 km running) across years from 1988 to 2011. METHODS For the cross-sectional data analysis, the association between with overall race times and split times was investigated using simp...

The role of the statistical model-based voice activity detector (SMVAD) is to detect speech regions from input signals using the statistical models of noise and noisy speech. The decision rule of SMVAD is based on the likelihood ratio test (LRT). The LRT-based decision rule may cause detection errors because of statistical properties of noise and speech signals. In this article, we first analyz...

Barefoot running has become a popular research topic, driven by the increasing prescription of barefoot running as a means of reducing injury risk. Proponents of barefoot running cite evolutionary theories that long-distance running ability was crucial for human survival, and proof of the benefits of natural running. Subsequently, runners have been advised to run barefoot as a treatment mode fo...

The dominance of East African distance runners and sprinters of West African origin invites discussion around the contribution of genetic and lifestyle factors to performance. In this review, we focus on the genetic basis for performance. Previous research associating candidate genes such as ACE and ACTN3 to endurance and sprint performance in Caucasian populations has not been replicated in Af...

Although WS-BusinessActivity and BPEL4WS Long-Running Transaction (LRT) are conceptually very similar and are both designed to support the execution of complex business transactions, they differ in a large number of aspects. This is particularly true because BPEL4WS, unlike WSBusinessActivity, was not designed to support distributed coordination. This paper comprehensively discusses the similar...

Deprivation of food, water, or individual nutrients usually causes an increase in the spontaneous running activity of the rate 9"'0, 170 2, U t, 2#,a8 although some exceptions have been reported.2,'7' ' The measurement of running activity has been used for investigations into motivation, for instance, as a measure of the hunger and thirst drives."90" Wald and Jackson considered the hyperactivit...

BACKGROUND In animals, neuropeptide signaling is an important component of circadian timekeeping. The neuropeptide pigment dispersing factor (PDF) is required for several aspects of circadian activity rhythms in Drosophila. METHODOLOGY/PRINCIPAL FINDINGS Here we investigate the anatomical basis for PDF's various circadian functions by targeted PDF RNA-interference in specific classes of Droso...
