Diffusion tensor tractography is increasingly used to examine structural connectivity in the brain in various conditions, but its test-retest reliability is understudied. The main purposes of this study were to evaluate 1) the reliability of quantitative measurements of diffusion tensor tractography and 2) the effect on reliability of the number of gradient sampling directions and scan repetiti...

In order to prevent unpleasant incidents, preservation high-speed railway vehicle stability has vital importance. For this purpose, railway vehicle is modeled using a 38-DOF. This paper presents an investigation on limit cycle and bifurcation of high speed railway behavior. It is revealed that the critical hunting speed decreases by increasing the wheel conicity. Also the critical hunting speed...

Contrary to what was said at the Environment Committee hearing on March 22nd, the Centers for Disease Control (CDC) do not recommend hunting to control Lyme disease. If one scours the CDC web pages on Lyme disease, many recommendations are given about how to prevent Lyme disease, but there is no mention of hunting in the CDC web page text, nor any recommendation for hunting 1 . See http://www.c...

TAYLOR, C. R., KNUT SCHMIDT-NIELSEN, RAZI DMI’EL, AND MICHAEL FEDAK. E$ect of hyperthermia on heat balance during running in the African hunting dog. Am. J. Physiol., 220(3): 823-827. 1971 .-The tricolored Cape hunting dog (Lycaon pi&s) is a doglike African carnivore. It hunts in packs and tirelessly runs down its prey. In experiments at 26 C, the running hunting dog had a higher rectal tempera...

PURPOSE To determine optimal MR gradient-echo sequences for the visualization of calcium in neurologic MR. METHOD The dependence of signal intensity and image contrast on the imaging parameters repetition time, echo time, flip angle, and spoiling were measured for hydroxyapatite samples. Calculations of signal intensity were shown to correspond to these measures. RESULTS Optimum detectabili...

By utilizing a racetrack resonator topography, an on-chip mode locked silicon evanescent laser (ML-SEL) is realized that is independent of facet polishing. This enables integration with other devices on silicon and precise control of the ML-SEL's repetition rate through lithographic definition of the cavity length. Both passive and hybrid mode-locking have been achieved with transform limited, ...

in this paper the effects of non-linearity of suspension on dynamic behavior of a railway wheelset has been studied. this wheelset has four degrees of freedom that with two constraints it has reduced to two degrees of freedom. vermeulen-johnson theory has been used to calculate contact forces between wheel and rail. in this study the creep coefficients have considered constant. any linearizatio...

The effect of forestland availability under different ownership types on license sales for hunting in nine Southeastern states is empirically evaluated. An equation that represents license sales for hunting is estimated assuming the sale of hunting licenses in a particular county is related to the characteristics of that county as well as the characteristics and license sales for hunting in its...

Once absent in much of Amazonia, dogs are now commonly used for hunting throughout the lowland Neotropics. Although some ethnographers have questioned their usefulness, dogs are particularly effective in pursuits of several mammalian prey species. The return rates of hunting with dogs appear to compare favorably with those of hunting with firearms, and dogs may be especially beneficial in anthr...
