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...

Freshly replicated DNA molecules initially form multiply interlinked right-handed catenanes. In bacteria, these catenated molecules become supercoiled by DNA gyrase before they undergo a complete decatenation by topoisomerase IV (Topo IV). Topo IV is also involved in the unknotting of supercoiled DNA molecules. Using Metropolis Monte Carlo simulations, we investigate the shapes of supercoiled D...

Polarization effect of the pulsed pumping laser on the lasing characteristics of the dye-doped right-handed cholesteric liquid crystal (CLC) is studied at different incident angles. At a small incident angle (<18 ), the CLC laser performance is independent of the polarization state of the pumping laser. As the incident angle exceeds 18 , the CLC laser emission strongly depends on the polarizati...

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...

In the present study we investigated planum temporale asymmetry and corpus callosum morphology in a sample of young adult left-handed males, using MRI. Two subgroups of left-handed males were identified on the basis of their differing speech lateralization patterns, which were inferred from results of the Fused Dichotic Words Test. These individuals then underwent MRI in order to obtain area me...

We develop an 0(18) theory of family unification consistent with all established phenomenology and cosmology. The theory makes firm predictions that will be tested soon. It implies that five new families live below 265 GeV. One of the new families is left-handed, and the other four are right-handed. The new left-handed family is lighter than its right-handed counterparts. The lightest right-han...
