Background and aims: The circadian rhythm is one the most important biological rhythms that regulates the sleep-wake cycle and repeats every 24 hours roughly. This 24-hour cycle includes physiological and behavioral rhythms like sleep cycle. Any disruptions in the body’s natural rhythms can cause many problems, such as drowsiness, sleep deprivation, reduced physical activity, and mental functio...
In this study, for the first time, we model gasoline consumption behavior in Iran using the long-term memory model of the autoregressive fractionally integrated moving average and non-linear Markov-Switching regime change model. Initially, the long-term memory feature of the ARFIMA model is investigated using the data from 1927 to 2017. The results indicate that the time series studied has a lo...

nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
radar transmitters emit high-power radiofrequency radiation by creation of a high-voltage and high-frequency alternating electrical current.health effects of occupational exposure to military radar were investigated. visual reaction time was recorded with a simple blind computer-assisted-visual reaction time test. to assess the short-term memory, modified wechsler memory scale test was performe...
background and aim: today, bilingualism is a developing phenomenon which half of the world population is bilingual. auditory system is the main route to language learning, so it is expected that bilingualism has an effect on functions of the auditory system. auditory memory is one of the auditory processes which is a cornerstone of linguistic skills and learning process growth, so that, it has ...
Investigators have begun to examine the fleeting urges and inclinations that subjects experience when performing tasks involving response interference and working memory. Building on this research, we developed a paradigm in which subjects, after learning to press certain buttons when presented with certain letters, are presented with two action-related letters (the memoranda) but must withhold...
when the past observations are correlated with future observations and their correlation is significant, the time series has long memory. in this paper the contagion effect of volatilities, with consideration of long-run effect, is investigated. the basic model is bekk (1, 1) and fbekk (1,d,1), model extended long-run memory parameter (d) is considered and estimated. furthermore in this paper p...
When an experience is encrypted into a long-lasting memory, it is believed that specific sets of neurons in the brain of the animal undergo changes including the strengthening of preexisting synapses and the growth and maintenance of new synaptic connections. These activity-dependent synaptic changes appear to require the coordination of a variety of cellular processes in spatially separated ce...
background: exposure to organic solvents is common among workers. objective: to assess neurobehavioral effects of long-term exposure to organic solvents among rubber workers in tehran, iran. methods: across-sectional study was conducted on 223 employees of a rubber industry. the participants completed a data collection sheet on their occupational and medical history, and demographic characteris...
