objectives : the study was designed to investigate the impairment of the ability to discriminate between nouns and verbs, resulting from the damage to the left-hemisphere, a condition which could lead to linguistic disorders proportionate to the depth and extent of the damage. various experimental and clinical investigations have demonstrated that nouns and verbs may, independent of one another...

We consider the problem of recognizing star-polygons under staircase visibility (s-visibility). We show that the s-visibility polygon from a point inside a simple orthogonal polygon of n sides can be computed in O(n) time. When the polygon contains holes the algorithm runs in O(n log n) time, which we prove to be optimal by linear time reduction from sorting. We present an algorithm for computi...

Given a planar polygon (or chain) with a list of edges {e1, e2, e3, . . . , en−1, en}, we examine the effect of several operations that permute this edge list, resulting in the formation of a new polygon. The main operations that we consider are: reversals which involve inverting the order of a sublist, transpositions which involve interchanging subchains (sublists), and edge-swaps which are a ...

Introduction. The recent emphasis on learning strategies and their effects on success has promoted researchers from different disciplines to carry out research in this regard. Methods. This paper reports the results of the study performed on 41 students, randomly selected out of 120 students, in an attempt to find out their learning style preferences. It has replicated the study presented by ...

objective hemiconvulsion-hemiplegia-epilepsy syndrome (hhe) is an initial phase of unilateral or predominantly unilateral convulsive seizures usually of long duration, with a second phase of hemiplegia (usually permanent), immediately following the hemiconvulsions;and then a third stage, characterized by the appearance of partial epileptic seizures. the causes of the initial convulsions in hhe ...

  Background :Older adults with cerebrovascular accident (CVA) show evidence of auditory and speech perception problems. In present study, it was examined whether these problems are due to impairments of concurrent auditory segregation procedure which is the basic level of auditory scene analysis and auditory organization in auditory scenes with competing sounds.   Methods : Concurrent auditory...

introduction: emotional words in comparison with neutral words have different hemispheric specialization. it is assumed that the right hemisphere has a role in processing every kind of emotional word. the objective of the present study was the development of a persian version of the dichotic emotional word test and evaluate its validation among adult persian speakers.   materials and methods: t...

It remains unsettled whether human language relies exclusively on innately privileged brain structure in the left hemisphere or is more flexibly shaped through experiences, which induce neuroplastic changes in potentially relevant neural circuits. Here we show that learning of second language (L2) vocabulary and its cessation can induce bidirectional changes in the mirror-reverse of the traditi...

Here we describe a new genus, for a new species of riffle beetle, Hypsilara royigen.n. and sp. n., from the tepui Cerro de la Neblina in southern Venezuela. This new genus can be distinguished from all other laraine genera by its small size (ca. 4.5 mm) and the presence of a shallow, wide, V-shaped groove across the apical third of the pronotum. An updated key to the genera of Western Hemispher...
