this paper examines the stylistics of the ‘arafa supplication in terms of their acoustic and phonetic levels. this supplication has a unique and consistent texture. the acoustic features of the words and sentences and the repetition of some sounds, words and phrases and acoustic syllables, as well as literary devices such as rhyme and paronomasia tend to increase the rhythm of speech. in fact, ...

For decades, theta rhythms (∼5-10Hz) have been thought to play a critical role in memory processing in the entorhinal-hippocampal network. However, recent evidence suggests that successful memory performance also requires coupling of ∼30-100Hz gamma rhythms to particular phases of the theta cycle. Recent insights imply ways in which theta-gamma coupling may facilitate transfer of information th...

poetic analysis involves the explication of a poem by focusing on the process of semiosis in it. through semiosis linguistic meaning is transformed into stylistic meaning. an examination of semiosis brings us to look at the hypersemanticized poetic structures which are none other than the style features of a poem. since style functions in a literary text by conveying meanings other than literal...

The brain is widely assumed to be a paradigmatic example of a complex, self-organizing system. As such, it should exhibit the classic hallmarks of nonlinearity, multistability, and "nondiffusivity" (large coherent fluctuations). Surprisingly, at least at the very large scale of neocortical dynamics, there is little empirical evidence to support this, and hence most computational and methodologi...
