This paper describes some Java releated aspects of TENT (TEstbed for Numerical Turbine simulation), a system designed for integrating various codes and tools of a Computational Fluid Dynamics (CFD) simulation system. TENT provides a distributed simulation environment for simulation tasks in energy and propulsion technology, and it allows to connect the diierent tools to an application scenario....

Botulinum neurotoxin (BoNT; serotypes A-G) and tetanus neurotoxin elicit flaccid and spastic paralysis, respectively. These neurotoxins are zinc proteases that cleave SNARE proteins to inhibit synaptic vesicle fusion to the plasma membrane. Although BoNT/B and tetanus neurotoxin (TeNT) cleave VAMP-2 at the same scissile bond, their mechanism(s) of VAMP-2 recognition is not clear. Mapping experi...

For improvement of spatial uniformity of negative ion beams, the external magnetic filter was replaced to a novel tent-shaped magnetic filter in the JAEA 10 ampere negative ion source. The tent filter geometry is based on new findings in surface production of negative ions in high electron temperature plasmas. In order to link the tent filter, the original line-cusp field configuration on the s...

TeNT is the causative agent of the neuroparalytic disease tetanus. A key component of TeNT is its light chain, a Zn(2+) endopeptidase that targets SNAREs. Recent structural studies of closely related BoNT endopeptidases indicate that substrate-binding exosites remote from a conserved active site are the primary determinants of substrate specificity. Here we report the 2.3 A X-ray crystal struct...

Abducens neurons undergo a dose-dependent synaptic blockade (either disinhibition or complete blockade) when tetanus neurotoxin (TeNT) is injected into the lateral rectus muscle at either a low (0.5) or a high dose (5 ng/kg). We studied the firing pattern and recruitment order in abducens neurons both in control and after TeNT injection. The eye position threshold for recruitment of control abd...

In their celebrated ”Period three implies chaos” paper, Li and Yorke proved that if a continuous interval map f has a period 3 point then there is an uncountable scrambled set S on which f has very complicated dynamics. One question arises naturally: Can this set S be chosen invariant under f? The answer is positive for turbulent maps and negative otherwise. In this note, we shall use symbolic ...

Outbreaks of folivorous Lepidoptera caterpillars are common in temperate forests (Ives and Wong 1988, Butterworth 1990). The high fat content, low chitin content, and large size of these larvae make them an important component of the diet of many temperate birds (Betts 1955, Robinson and Holmes 1982, Holmes and Schultz 1988, Sample et. al. 1993). Outbreaks of most species should increase availa...

This paper describes the design of a modified tent map characterized by a uniform probability density function. The use of this map is proposed as an alternative to the tent map and the Bernoulli shift. It is shown that practical circuits implementing the latter two maps may possess parasitic stable equilibria, fact which would prevent the desired chaotic behavior of the system. On the other ha...
