OBJECTIVE To investigate the maxillary and mandibular anterior crown width/height ratio and its relation to various arch perimeters, arch length, and arch width (intercanine, interpremolar, and intermolar) groups. MATERIALS AND METHODS The calculated sample size was 128 subjects. The crown width/height, arch length, arch perimeter, and arch width of the maxilla and mandible were obtained via ...

Facial characteristics are an important basis for judgements about gender, emotion, personality, motivational states and behavioural dispositions. Based on a recent finding of a sexual dimorphism in facial metrics that is independent of body size, we conducted three studies to examine the extent to which individual differences in the facial width-to-height ratio were associated with trait domin...

While measuring the ratio RK = Γ(K± e2(γ))/Γ(K ± μ2(γ)), the KLOE Collaboration has studied the radiative process Ke2γ . The ratio of the width for the Ke2γ decay with a positively polarized photon from structure-dependent radiation to the inclusive Kμ2(γ) width is found to be 1.484(68)×10−5. The observed radiation spectrum agrees with predictions from chiral perturbation theory and is in contr...

The Young's modulus of ZnO nanobelts was measured with an atomic force microscope by means of the modulated nanoindentation method. The elastic modulus was found to depend strongly on the width-to-thickness ratio of the nanobelt, decreasing from about 100 to 10 GPa, as the width-to-thickness ratio increases from 1.2 to 10.3. This surprising behavior is explained by a growth-direction-dependent ...
