s | 43 (sleep) and molecular mechanisms involved in contextual processing deficits. Methods The evolution of functional neuroimaging studies from early studies of responses to emotional probes to recent multi-day studies of fear conditioning, extinction, renewal, and of intrinsic connectivity networks, will be discussed and novel finding presented. Parallel findings from studies using Single Pr...

in the present study, air quality analyses for ozone (o3) were conducted in shiraz, a city in the south of iran. the measurements were taken from 2011 through 2012 in two different locations to prepare average data in the city. the average concentrations were calculated for every 24 hours, each month and each season. results showed that the highest concentration of ozone occurs generally in the...

This paper presents an analytical model of TCP Reno throughput as a function of loss event rate, average round trip time, average retransmission timeout value, and receiver window size based on the model proposed by Padhye et al. (widely known as the PFTK-model in correspondence with the initials of the authors). The presented model refines previous work by careful examination of fast retransmi...

we apply the two-sector production function developed by ram (1986) to estimate the threshold regression model for iran, concerning the effect of government size on economic growth. three government size indicators are used to find out the different threshold points. the results show a non-linear relationship of the armey curve in iran, in which the threshold effects corresponding to total gove...

new statistic based models provide a wide area of prediction equipments for different science areas. among these fields biology have just entered the contest of interdisciplinary sciences. drug discovery is a long and expensive process which could be decreased with theoretical approaches. in this study, 500 reported assayed anti cancer molecules were extracted from science direct articles, sket...

difference aspects of multinomial statistical modelings and its classifications has been studied so far. in these type of problems y is the qualitative random variable with t possible states which are considered as classifications. the goal is prediction of y based on a random vector x ? ir^m. many methods for analyzing these problems were considered. one of the modern and general method of cla...

the objective of this article is to analyze the data collected by the depart­ment of environmental health about the susceptibility of anopheles stephensi in the minab shahrestan to d.d.t. from 1957 to 1968, in order to: determine a mathematical model for the changes in l.d.50 by time and estimate the trend of l.d.50, for the future years. by plotting the changes in the resistance of the mosquit...
