Study of the Higgs boson property in ZH → qqH

Higgs boson is the Standard Model (SM) particle predicted as the origin of the mass. Precise measurement of the Higgs boson properties is an important issue of the International Linear Collider (ILC) experiment. We studied the measurement accuracy of the Higgs boson property in the ZH → qq^^-H multi-jet process with the cutbased analysis assuming the 120 Gev Higgs mass at √=250 GeV with the ILD detector model

Comparison of the Physiological Properties of Human Periodontal-Masseteric Reflex Evoked by Incisor and Canine Stimulation

Introduction: The present study was designed to clarify whether the bilateral cooperation in the human periodontal-masseteric reflex (PMR) differs between central incisors and canines. Methods: Surface array electrodes were placed on the bilateral masseter muscles to simultaneously record the firing activities of single motor units from both sides in seven healthy adults. During light clenching, mechanical stimulation was applied to the right maxillary central incisor and canine to evoke the PMR. Unitary activity was plotted with respect to the background activity and firing frequency. The slope of the regression line (sRL) and the correlation coefficient (CC) between the central incisor and canine and the lateral differences between these values were compared. Results: There were significant differences in the sRL and CC, as well as lateral differences, between the central incisor- and canine-driven PMR. Discussion: These results suggest that the PMR differs depending on both the tooth position and laterality

Terrestrial ages of Antarctic meteorites measured by thermoluminescence of the fusion crust

The acquired doses of 14 Antarctic meteorites were measured using the thermoluminescent (TL) intensity of the fusion crust. It was found that there is a good correlation between the acquired TL doses and the terrestrial ages, which were previously measured by the cosmogenic radionuclide abundance

PIXE analysis of magnetic spherules in Paleozoic-Mesozoic bedded chert

Particle Induced X-ray Emission (PIXE) was applied to the elemental characterization of magnetic microspherules collected from the Paleozoic and Mesozoic bedded chert in Southwest Japan. Comparison of the titanium and chromium contents of the spherules with the magnetic components of meteorites and volcanic ash showed that this technique offers promising potential as a new method for distinguishing between spherules of terrestrial and extraterrestrial origin
