Brain activity related to time estimation processes in humans was analyzed using a perceptual phenomenon called auditory temporal assimilation. In a typical stimulus condition, two neighboring time intervals (T1 and T2 in this order) are perceived as equal even when the physical lengths of these time intervals are considerably different. Our previous event-related potential (ERP) study demonstr...

The N400 event-related potential could index the activation/integration of representations corresponding to the stimulus or, on the contrary, the inhibition of representations that have been inappropriately activated. To test this alternative, series of 3 words were visually presented to subjects in a relatively rapid succession in order to prevent any disengagement of attention. In one block, ...

groundwater can be used directly or indirectly and any decline in its quality or quantity maynegatively impact the environment. through groundwater valuation, people are made aware of the fact thatgroundwater is not free of charge and therefore the significance of groundwater preservation is established. in this study, groundwater quality preservation value has been estimated for the city of ya...

This paper presents a method for allocation and evaluation of reactive power (VAr) support contracts necessary to maintain system security and quality of supply. The method also quantifies the value of VAr support from individual generators or a portfolio of generators. Such information may be useful both to generating companies in preparing VAr tenders and to the market operator in assessing t...

Older and younger aerobically trained and sedentary adults participated in an S1-S2-S3 paradigm designed to elicit event-related potential (ERP) and behavioral responses to determine the influence of cardiovascular fitness on cognitive and motor processes. The paradigm provided warning (S1) as to the difficulty level of an upcoming decision task (S2). Participants had to decide the taller of tw...

this study has been conducted for the first time in iran, by contingent valuation method (cvm) and using extended linear expenditure system (eles) to estimate nonrnarket services of gerebygan manmade forest. according to this study the existance value of three principal nonrnarket services including climat regulation, erosion control and habitat/refugia estimated respectively at 32250934930 ria...

Gaze-contingent display paradigms play an important role in vision research. The time delay due to data transmission from eye tracker to monitor may lead to a misalignment between the gaze direction and image manipulation during eye movements, and therefore compromise the contingency. We present a method to reduce this misalignment by using a compressed exponential function to model the traject...

In this paper, we present the fundamental framework of the evaluation problem under which the evaluation operator satisfying some axioms is linear. Based on the dynamic linear evaluation mechanism of contingent claims, studying this evaluation rule in the market driven by fractional Brownian motions has led to a dynamic capital asset pricing model. It is deduced here mainly with the fractional ...

The transition from late adolescence to young adulthood is often overlooked in the cognitive neuroscience literature. However this is an important developmental period as even older adolescents have not yet reached adult level ability on many cognitive tasks. Adolescents (16-17-year olds) and young adults (23-30-year olds) were tested on a cued task switching paradigm specifically designed to i...
