This contribution describes traffic models that provide typical self-similar traffic for data applications and interrupted Poisson (or on-off) models for streaming media applications for a point-to-multipoint fixed wireless WAN application. The contribution specifies the traffic models for various proto-typical cases. It also provides a definition of what(More)
Recently fibroblast growth factor 21 (FGF21) has been identified as a potent regulator in glucose and lipid homeostasis. Here, we firstly investigated the metabolic role of FGF21 in human liver-derived HepG2 cells, and suggested that overexpression of FGF21 suppressed triglyceride accumulation by inhibiting the transcription of the gene necessary for de(More)
Low-power design is essential for passive RFID tags to achieve expected level of sensitivity. Considering the mechanism of the passive tags powered, a low peak power is also important. This paper is focused on optimization on peak power. A tag IC is also presented. The IC, which is compatible with the EPC C1G2 RFID protocol, was designed and fabricated(More)
This paper reports the availability of a database of protein structural domains (DDBASE), an alignment database of homologous proteins (HOMSTRAD) and a database of structurally aligned superfamilies (CAMPASS) on the World Wide Web (WWW). DDBASE contains information on the organization of structural domains and their boundaries; it includes only one(More)
OBJECTIVE To investigate the changes in behavioristics, substantia nigra tyrosine hydroxylase (TH) immunoreactive cells, and ultrastructure of substantia nigra neurons in rats after manganese exposure via intracerebral injection. METHODS A total of 72 healthy male Sprague-Dawley rats were randomly divided into exposure group and control group, with 36(More)
The beta-NADPH histochemical method was used to study the effect of lead on activity of nitric oxide synthase(NOS) in neurons and vessel smooth muscles of intestinal wall in rats. The results showed that the number of NOS positive neurons and fibers was decreased and degenerative changes of some NOS positive neurons were found after the lead acetate(More)
A simulation model is developed in this study for managing state highway maintenance. The purpose of this model is to develop causal links between revenue sources and expense demands of highway maintenance so as to suggest how to formulate cost allocation policies and programming strategies that are fair, economic and sustainable.
