The present study investigated differences in height, weight, and body mass index (BMI) between left-handed and right-handed Japanese professional baseball pitchers and batters. Some 345 pitchers and 356 batters who played in 2001, and 352 pitchers and 269 batters who played in 2011 were evaluated. Analyses of variances (ANOVAs) revealed significant differences in height and weight, but not BMI...

We study the difference between the standard seeded model of tile self-assembly, and the “seedless” two-handed model of tile self-assembly. Most of our results suggest that the two-handed model is more powerful. In particular, we show how to simulate any seeded system with a two-handed system that is essentially just a constant factor larger. We exhibit finite shapes with a busy-beaver separati...

Subendocardial and subepicardial layers of the left ventricle (LV) are characterized with right- and left-handed helical orientations of myocardial fibers. We investigated the origin of biphasic deformations of the LV wall during isovolumic contraction (IVC) and relaxation (IVR). In eight open-chest adult pigs, strain rates were measured along the right- and left-handed helical directions in th...

The thermodynamics of rightand left-handed helix formation by poly[d(G-C)].poly[d(G-C)] and by poly(dG-mSdC).poly(dG-msdC) were measured spectrophotometrically and calorimetrically. From the spectrophotometric measurements the thermal stabilities of the alternative helical conformations were evaluated as a function of counterion concentration. From the calorimetric measurements the enthalpies o...

WHY ARE YOU LEFT-HANDED? Despite many years of research, the reason why one person turns out to be a left-hander and another does not remains a mystery. Handedness is partly heritable (see Glossary): left-handed parents tend to have more left-handed children than right-handed parents do. Studies that compared identical twins to fraternal twins (see Glossary) show that the heritability is around...

We give a new, significantly shorter proof of the completeness of the left-handed star rule of Kleene algebra. The proof reveals the rich interaction of algebra and coalgebra in the theory.

UNLABELLED BACKGROUND Radiosensitivity is an inheriting trait that mainly depends on genetic factors. it is well known in similar dose of ionizing radiation and identical biological characteristics 9-10 percent of normal population have higher radiation response. Some reports indicate that distribution of breast cancer, immune diseases including autoimmune diseases as example lupus, Myasthen...

[Purpose] The purpose of this study was to research the difference in wrist flexion and accuracy of left-handers when using regular scissors made for right-handed persons versus scissors made for left-handers. [Subjects and Methods] Eighteen left-handers participated in the experiment. There were ten males and eight females subjects. The degree of wrist flexion of 18 left-handers was analyzed w...
