introduction: neonatal hyperbilirubinemia is one of the most important factors affecting the auditory system and can cause sensorineural hearing loss. this study investigated the relationship between behavioral hearing thresholds in children with a history of jaundice and the maximum level of bilirubin concentration in the blood.   materials and methods: this study was performed on 18 children ...

one of the identified risk factors for anxiety disorders in adolescence and adulthood is inhibited behaviors in childhood. the present study sought to examine the relationship between behavioral inhibition with some of the internal (personal) and external (family environment) factors in a sample of preschool children in kindergartens. in a cross sectional study in 2009, data was collected troug...

We argue that behavioral science models of online content-sharing overlook the role strategic interactions between users. Borrowing from accuracy-nudges studies decision-theoretic models, we propose a basic game model and explore special cases with idealized parameter settings to identify refinements necessary capture real-world social network behavior. Anticipating those refinements, sketch an...

the genetic parameters and (co) variance components of body weight at birth (bw), weaning (ww) and six months of age (bw6) and average daily gain (adg) pre and post-weaning of afshari sheep were estimated using restricted maximum likelihood (reml) methodology and animal model implemented in dfreml software. the likelihood ratio test (lrt) was used to compare the models. year of birth, age of mo...

Using evolutionary simulations, we develop autonomous agents controlled by artificial neural networks (ANNs). In simple lifelike tasks of foraging and navigation, high performance levels are attained by agents equipped with fully recurrent ANN controllers. In a set of experiments sharing the same behavioral task but differing in the sensory input available to the agents, we find a common struct...
