Previous research supported that the prevalence of addiction is related to brain laterality. Brain laterality is often determined by left/right handedness and this phenomenon is considered as an important factor in addiction prevalence. The present study attempts to examine the relationships between left/right handedness with addiction and smoking on Iranian population. In this study, 2000 male...

The con ver sion of right-handed dsDNA and dsRNA to the left-handed Z-con-formation in volves a re or ga ni za tion of the nu cleo tides rel a tive to each other. This con-ver sion can be fa cil i tated by the tight bind ing of a Z-conformation-specific pro tein domain from the ed it ing en zyme dsRNA adenosine deaminase. This may in flu ence the mod i fi ca tion of both pre-mRNAs as well as so...

Metamaterials are artificial structures that are designed to exhibit specific electromagnetic properties required for different applications but not commonly found in nature. The methodology of synthesizing materials composed of microand nano-structured components that mimic the electromagnetic response of individual atoms and molecules (meta-atoms and meta-molecules) has proven to be very prod...

An analytical theory is developed for parametric interactions in metamaterial multilayer structures with simultaneous nonlinear electronic and magnetic responses and with a near-zero refractive index. We demonstrate theoretically that electromagnetic fields of certain frequencies can be parametrically shielded by a nonlinear left-handed material slab, where the permittivity and permeability are...

introduction: currently, neuroresearchers report that the median nerve shows severity-correlated intracarpal enlargement in idiopathic carpal tunnel syndrome (cts) as a most common peripheral neuropathic disorder. the purpose of this paper was to investigate ultrasonography morphological findings in patients with idiopathic cts and comparing some physical properties such as age, gender, bmi wit...

We show that surface electromagnetic waves (SEMWs) propagating along two-dimensional (2D) interfaces separating different metamaterials can behave analogously to 3D electromagnetic waves in either usual or left-handed media, depending on the permeabilities and/or permittivities of the two materials forming the interface. We derive the conditions when SEMWs carry energy opposite to the phase vel...

We analyze the properties of microstructured materials with negative refraction, the so-called left-handed metamaterials. We consider a two-dimensional periodic structure created by arrays of wires and split-ring resonators embedded into a nonlinear dielectric, and calculate the effective nonlinear electric permittivity and magnetic permeability. We demonstrate that the hysteresis-type dependen...

For isotropic and homogeneous nonlinear left-handed materials, for which the effective medium approximation is valid, Maxwell's equations for electric and magnetic fields lead naturally, within the slowly varying envelope approximation, to a system of coupled nonlinear Schrodinger equations. This system is equivalent to the well-known Manakov model that under certain conditions, is completely i...
