Fluorescent indicators were used to detect stimulus-evoked changes in presynaptic levels of intracellular sodium (Na1) and calcium (Ca1) in granule cell parallel fibers in brain slices from rat cerebellum. Ca, increased during stimulation, and three exponentials were needed to approximate its return to prestimulus levels. Ca, decayed to -10% of peak levels with T 100 ms, to -1% of peak values w...

Contamination of pistachio nuts by aflatoxigenic strains of Aspergillus species is the greatest constraint to production and export of pistachio nuts in Iran, the leading producer of pistachio nuts in the world. Kerman province is the main region in Iran where 85%, of pistachio nuts are produced. Determining the population density of Aspergillus spores in the orchards and terminals which are th...

Due to the urban expansion and population increasing, bus network design is an important problem in public transportation. Functional aspect of networks such as fuel consumption depreciation buses also spatial aspects station terminal locations or access rate are not proper conditions most cities. Therefore, having efficient method evaluate performance lines by considering both functional essen...

In this paper, we introduce a new model for sublinear algorithms called dynamic sketching. In this model, the underlying data is partitioned into a large static part and a small dynamic part and the goal is to compute a summary of the static part (i.e, a sketch) such that given any update for the dynamic part, one can combine it with the sketch to compute a given function. We say that a sketch ...

Traditional design of user interfaces for mobile phones is limited to a small interaction that provides only the necessary means to place phone calls or to write short messages. Such narrow activities supported via current terminals suppress users from moving towards mobile and ubiquitous computing environments of the future. Unfortunately, the next generation of user interfaces for mobile term...

networks have historically been designed primarily to extend the domain of circuit-switched telephone service over a wireless last hop (i.e., cellular telephony). However, wireless networks that support data in addition to voice have now begun to appear. Initially, this has taken the form of circuit-switched and packet-switched data services overlaid on top of existing wireless networks , such ...

Previous electron microscopic studies of synaptic terminal distributions in the lateral geniculate nucleus have been flawed by potential sampling biases favoring larger synapses. We have thus re-investigated this in the geniculate A-laminae of the cat with an algorithm to correct this sampling bias. We used serial reconstructions with the electron microscope to determine the size of each termin...

background: along with the rapid growth of technology its related tools such as computer, monitors and video display terminals (vdts) grow as well. based on the studies, the most common complaint reported is of the vdt users. methods: this study attempts to design a proper tool to assess the visual fatigue of the vdt users. first draft of the questionnaire was prepared after a thorough study on...

The development of Power Internet Things has brought a variety access requirements for massive collecting terminals. Based on the characteristics security attributes Things, this paper proposes secure protocol based symmetric cryptographic algorithm large number terminals with limited manufacturing cost, computing power and storage resources. This only uses which fast speed low resource consump...
