Environment matting is a powerful technique for modelling the complex light-transport properties of real-world optically active elements: transparent, refractive and reflective objects. Zongker et al [1999] and Chuang et al [2000] show how environment mattes can be computed for real objects under carefully controlled laboratory conditions. However, for many objects of interest, such calibration...

Sensory areas of adult cerebral cortex can reorganize in response to long-term alterations in patterns of afferent signals. This long-term plasticity is thought to play a crucial role in recovery from injury and in some forms of learning. However, the degree to which sensory representations in primary cortical areas depend on short-term (i.e., minute to minute) stimulus variations remains uncle...

The tactile sensations mediated by the whisker-trigeminal system allow rodents to efficiently detect and discriminate objects. These capabilities rely strongly on the temporal and spatial structure of whisker deflections. Subthreshold but also spiking receptive fields in the barrel cortex encompass a large number of vibrissae, and it seems likely that the functional properties of these multiwhi...

The present study sought to investigate the effect of explicit instruction of lexical bundles (LBs) on the development of Iranian English for Academic Purposes (EAP) students’ writing quality and also their receptive and productive knowledge of Lexical Bundles (LB). Assigned to two experimental and control groups, the eighty participants took pre- and post-tests of writing tasks and the recepti...

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...

abstract   introduction: one of the most common behavioral problems in children with intellectual disability is physical aggression. physical aggression is described as behaviors such as hitting, kicking, throwing object and threatening with the intent to harm others. physical aggression is related to the different factors such as language skills, which has been examined among intellectually di...

«corporate social responsibility» is the term of 1990 extensively, with the liberation of the economy and a profound gap between the role of the social and economic, was created, emerged. the theory is, at first, be fitted; as effects alien before it aspect of the commercial enterprises, solely for economic activity for your maximum profit for attention of return and profit without cost, for it...

In the mammalian visual cortex, orientation-selective 'simple cells' which detect straight lines may be adapted to detect curved lines instead. We test a biologically plausible, Hebbian, single-neuron model, which learns oriented receptive fields upon exposure to unstructured (noise) input and maintains orientation selectivity upon exposure to edges or bars of all orientations and positions. Th...
