Evidence is presented that RHD, RHCE, and other RH genes, may be interesting candidates to consider when searching for the genetic basis of hair whorl rotation (i.e., clockwise or counterclockwise), handedness (i.e., right handed, left handed or ambidextrous), speech laterality (i.e., right brained or left brained), speech dyslexia (e.g., stuttering), sexual orientation (i.e., heterosexual, hom...

We study analytically and numerically the impact of second-neighbor interactions on propagation an initial wave-packet through a coupled nonlinear left-handed transmission line. start with detailed analysis dispersion curve group velocity. then use quasi-discrete approximation respect to long wavelength transverse perturbations reduce discrete model lattice Schrödinger equation. A product veloc...

The design presented here mainly focuses on implementation of a broadband Wilkinson balun using composite right/left-handed (CRLH) transmission line. This has its components, namely Wilkinson power divider (WPD), microstrip phase shift line and CRLH unit cell along with interdigital capacitor, which forms base of the unit cell. The designing and implementation of WPD, CRLH unit cell and Interdi...

Right hemispheric stroke aphasia (RHSA) rarely occurs in rightor left-handed patients with their language representation in right hemisphere (RH). For right-handers, the term crossed aphasia is used. Single cases, multiple cases reports, and reviews suggest more variable anatomo-clinical correlations. We included retrospectively from our stroke data bank 16 patients (rightand left-handed, and a...

We study both linear and nonlinear surface waves localized at the interface separating a left-handed (LH) medium (i.e., a medium with both negative dielectric permittivity and negative magnetic permeability) and a conventional [or right-handed (RH)] dielectric medium. We demonstrate that the interface can support both TE- and TM-polarized surface waves-surface polaritons, and we study their pro...

OBJECTIVE The study aims to compare transcallosal inhibition (TI), as assessed by the paired-pulse transcranial magnetic stimulation (TMS) technique, in a sample of right-handed subjects (RH) and left-handed subjects (LH). Motor thresholds (MTs) and motor evoked potential (MEP) amplitudes were also measured in the two groups, as an index of corticospinal activity. METHODS Thirty-two normal su...

purpose: the traditional view regards limb selection in reaching a hemispheric specialization and an permanent biological phenomenon. however, recent studies have questioned this idea. instead, they suggest that the task conditions is also an effective factor. the present study includes two experiments in right and left handed children examining the effect of object location as a task condition...
