– event synchronization: the process is always able to react to events of the environment at a rate determined by the environment; – response synchronization: the response synchronizes properly with the environment, i.e., the time elapsed between a stimulus and the response of the process is short enough (relatively to the dynamics of the environment) so that the environment is still receptive ...

Pollution of marine waters is one of the important issues that has a irreparable effects. Also, in the organic oil pollutants, due to inappropriate effects on the environment and humans health and ability to create cancer, hydro carbons of polycyclic (PAHS) and heavy metals (Ni,Hg,V) have a particular importance. According to the importance of study of the environ mental contaminants in the fou...

The efficient coding hypothesis holds that neural receptive fields are adapted to the statistics of the environment, but is agnostic to the timescale of this adaptation, which occurs on both evolutionary and developmental timescales. In this work we focus on that component of adaptation which occurs during an organism’s lifetime, and show that a number of unsupervised feature learning algorithm...

Most trainings of communicative behavior focus on fostering the observable speech productive behavior (i.e. speaking). The individual cognitive processes underlying speech receptive behavior (hearing and understanding utterances) thus are often neglected. This is due to the fact that speech receptive behavior cannot be accessed in the midst of a conversation and that its training is very time-c...

In this study, we examined the developmental pathways from children's family environment to school readiness within a low-income sample (N = 1,046), with a specific focus on the role of sustained attention. Six distinct factors of the family environment representing maternal parenting behaviors, the physical home environment, and maternal mental health at 3 years of age were explored as indepen...

objectives: one of the factors predicting language impairments is an early limited lexicon in children. an early limited lexicon can also lead to limited performances in other language areas. this study was aimed to examine receptive and expressive vocabulary in 8-16 month-old children with cleft lip and palate as a predictor of development in other language areas. materials: the macarthur-bate...

INTRODUCTION Drug law enforcement is part of the HIV risk environment among people who inject drugs (PWID). Punitive policing practices such as extrajudicial arrests for needle possession and police planting of drugs have been described anecdotally in Russia, but these experiences and their associations with risky drug behaviours have not been quantified. This study aims to quantify the burden ...

Background Earlier it was believed that uterine fluid (UF) or secretions are not relevant after the embryo implantation in humans. However, recent reports suggest that uterine secretions continue to play important role till the first trimester of human pregnancy. Evidences also suggest that uf mirrors endometrial functions or dysfunctions. Considering the relevance of uf in endometrial function...

In this paper, we describe the artificial evolution of adaptive neural controllers for an outdoor mobile robot equipped with a mobile camera. The robot can dynamically select the gazing direction by moving the body and/or the camera. The neural control system, which maps visual information to motor commands, is evolved online by means of a genetic algorithm, but the synaptic connections (recept...

The nervous system must dynamically represent sensory information in order for animals to perceive and operate within a complex, changing environment. Receptive field plasticity in the auditory cortex allows cortical networks to organize around salient features of the sensory environment during postnatal development, and then subsequently refine these representations depending on behavioral con...
