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...

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...

In this study, we examined hemispheric differences in corticospinal excitability and in transcallosal inhibition in a selected group of young adults (n = 34) grouped into three handedness categories (RH: strongly right-handed, n = 17; LH: strongly left-handed, n = 10; MH: mixed-handed, n = 7) based on laterality quotients (LQ) derived from the Edinburgh Handedness Inventory. Performance measure...

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...

We demonstrate experimentally a mechanism of the soliton generation in nonlinear active metamaterials. Our meta-structure consists of a ring resonator formed by a microwave amplifier loaded with a left-handed transmission line. We demonstrate a variety of nonlinear effects not described by weakly nonlinear models, and study experimentally the system’s spatiotemporal dynamics, including the gene...

background: luteinizing hormone (lh) was secreted by the stimulating cells of the testes and ovaries in the anterior pituitary gland. the application of this hormone is in the treatment of men and women with infertility and amenorrhea respectively. m aterials and methods: in the present study the alpha and beta subunits of human lh gene were cloned into the pegfp-n1 expression vector and produc...

In this present article, we studied the transmission, refraction and focusing properties of one, two and three dimensional labyrinth based left-handed metamaterials. We demonstrated that the proper periodic arrangement of labyrinth structures and wires results in left-handed transmission. By using a two dimensional labyrinth based left-handed slab, it is shown that it is possible to image the f...

Background. The double haul is a unique feature of single-handed fly casting and is used in both fly fishing and fly casting competition. The movement behaviour during the double haul has not been investigated in previous research. Objectives. Describe the coordination of the rod and line hauling movements during distance fly casting. Methods. Elite fly casters performed distance castin...
