Modeling of MTM compact ultra wideband resonant (CUWBR) antenna with A-shaped lefthanded structure has been proposed. The proposed MTM structure is modeled at a height of 0.8mm from the ground plane for 15.5GHz to 19.2GHz applications. The most interesting feature of the design is the ability of enhancing the gain and total efficiency of the antenna without negative effecting of the other impor...

Handedness, Health and Cognitive Development: Evidence from Children in the NLSY Using data from the US National Longitudinal Survey of Youth, and fitting family fixed-effects models of child health and cognitive development, we test if left-handed children do significantly worse than their right-handed counterparts. The health measures cover both physical and mental health, and the cognitive d...

We present a detailed investigation of the dynamical behavior of emerging magnetic flux using 3dimensional MHD numerical simulation. A magnetic flux tube with a lefthanded twist, initially placed below the photosphere, emerges into the solar atmosphere. This leads to a dynamical expansion of emerging field lines as well as an injection of magnetic energy and magnetic helicity into the atmospher...

We describe consequences of the chiral anomaly in the theory of quantum wires, the (quantum) Hall effect, and of a four-dimensional cousin of the Hall effect. We explain which aspects of conductance quantization are related to the chiral anomaly. The fourdimensional analogue of the Hall effect involves the axion field, whose time derivative can be interpreted as a (space-time dependent) differe...

The aim of this study was to investigate the distribution of specific phenotypes in patients with lung diseases as well as their eventual association with the risk of developing lung diseases. For this purpose 2777 patients with lung diseases and 2778 healthy individuals from all over Kosova were examined for the appearance of the following selected phenotypes: ear lobe free (ELF)/ear lobe atta...

We have evaluated the B to Z conformational transitions in supercoiled recombinant plasmids containing different lengths of (dC-dG) described in the preceding paper. The sodium chloride-induced rightto lefthanded transition in a small segment of the plasmids caused a relaxation of (-) supercoils which was monitored by electrophoretic mobility changes of individual topoisomers on agarose gels c...

We study the exactly degenerate case for three lefthanded Majorana neutrinos building a general parametrization for the leptonic mixing matrix characterized by two angles and one CP violating phase and identify a weak-basis invariant relevant, in this case, for CP violation. After lifting the degeneracy, this parametrization accommodates the present data on atmospheric and solar neutrinos, as w...

A fully printable and conformal antenna array on a flexible substrate with a new LeftHanded Transmission Line (LHTL) phase shifter based on a tunable Barium Strontium Titanate (BST)/polymer composite is proposed and computationally studied for radiation pattern correction and beam steering applications. First, the subject 1× 4 rectangular patch antenna array is configured as a curved conformal ...

Consider quantum chromodynamics (QCD) with color group SU(3) and three flavors of massless quarks. The lagrangian is invariant under an additional global flavor group, U(3)L × U(3)R. Although we will use it anyway, this “left–right” terminology is actually somewhat misleading; in four dimensions, a right-handed fermion field is the hermitian conjugate of a left-handed fermion field, and so we c...

Circular Polarization is a method in which the electric field of the passing wave does not change the strength but only changes direction in a rotary manner. Circular polarization may be referred to as right-handed or lefthanded, and clockwise or anti-clockwise, depending on the direction in which the electric field vector rotates. Circular polarization is often used erroneously to describe mix...
