J-PARC Neutrino Beamline Upgrade Technical Design Report
- 2019
-
Rapport (refereegranskat)abstract
- In this document, technical details of the upgrade plan of the J-PARC neutrino beamline for the extension of the T2K experiment are described. T2K has proposed to accumulate data corresponding to 2×1022 protons-on-target in the next decade, aiming at an initial observation of CP violation with 3σ or higher significance in the case of maximal CP violation. Methods to increase the neutrino beam intensity, which are necessary to achieve the proposed data increase, are described.

- Introduction The presence of an eroded or thinned cortex of the mandible on panoramic radiographs may be useful in identifying women with osteoporosis. However, little is known as to whether a non-eroded thin cortex predicts osteoporosis. Objective To clarify whether visual assessment of non-eroded thin cortex increases the diagnostic efficacy of identifying women with osteoporosis. Materials and methods Of 60 observers who participated in OSPD (Taguchi et al., Bone, 2008), 41 observers visually assessed non-eroded thin cortex in addition to Klemetti’s index (KI) for 100 panoramic radiographs on the OSPD website via the Internet twice with approximately a two-week interval. The area under the receiver operating characteristics curves (AUROC) in identifying women with osteoporosis by both KI and non-eroded thin cortex was calculated on two occasions; non-eroded thin cortex was included in “class 1 of KI (decreased probability of osteoporosis)” or “class 3 of KI (increased probability of osteoporosis)”. Mean AUROC was compared between these two occasions with paired ttest. Results In the first series of observations, the mean AUROC significantly increased when noneroded thin cortex was considered as a sign of increased probability of osteoporosis (mean +/- SD, 0.68 +/- 0.08 vs. 0.70 +/- 0.07, P=0.011). In the second set of observations, the result was unchanged (0.68 +/- 0.09 vs. 0.71 +/- 0.08, P<0.001). Conclusions and discussion Visual identification of a non-eroded thin cortex on panoramic radiographs may increase the diagnostic efficacy of identifying women with osteoporosis.

Dental panoramic radiograph as a tool to detect postmenopausal women with low bone mineral density : untrained general dental practitioners’ diagnostic performance

- The detection of postmenopausal women with low bone mineral density (BMD) is an important strategy to reduce the incidence of osteoporotic fracture. Recent studies suggested that incidental findings on dental panoramic radiographs may be used as a tool to detect women with low BMD. However, little is known whether this finding is sufficiently assessed by untrained general dental practitioners (GDPs). The purpose of this study was to investigate: (1) the observer agreement and (2) the diagnostic efficacy in detecting women with low BMD, when untrained GDPs assess the appearance (normal or eroded) of the mandibular inferior cortex on dental panoramic radiographs of postmenopausal women. Twenty-seven GDPs were asked to classify the appearance of the mandibular inferior cortex on dental panoramic radiographs of 100 postmenopausal women who had completed BMD assessments of the lumbar spine and of the femoral neck. Intra- and inter-observer agreements were analyzed with kappa statistics. The diagnostic efficacy (sensitivity, specificity and predictive values) was analyzed by comparing two groups classified by the mandibular inferior cortex (women with normal and women with eroded mandibular inferior cortex) with those classified by BMD (women with normal BMD and women with osteopenia or osteoporosis). The mean sensitivity and specificity were 77 % and 40 %, respectively, when BMD of the lumbar spine was used as standard and 75 % and 39 %, respectively, when BMD of the femoral neck comprised the standard. Nineteen untrained GDPs (70 %) presented a moderate to almost perfect intra-observer agreement. We conclude that dental panoramic radiograph may be used in clinical dental practice to identify postmenopausal women who have undetected low BMD and should undergo further testing with bone densitometry.

A kinetic model on oxygen transfer at a steel/slag interface under effect of interfacial tension

- A kinetic model was developed to predict the dynamic change of the oxygen content in the sub-interface region as well as the dynamic change of the interfacial tension between molten steel and slag. The dynamic steel/slag interfacial phenomena are very complex, where the combined effect of thermodynamics and kinetics on the interfacial tension needs to be accounted for. As a first step, the current model only considers the SiO2 decomposition, oxygen adsorption and desorption at the steel/slag interface to realize the modeling of the dynamic change of the steel/slag interface phenomena. The oxygen desorption rate was derived based on the slope of the interfacial tension change over oxygen content. Specifically, the oxygen change with time in a sub-interface was predicted by the current model. The oxygen desorption rate was found to have an important influence on the dynamic change of the oxygen content in the sub-interface region. Furthermore, a low slag viscosity was found to increase the oxygen content at the interface due to the fast supply of SiO2 from the slag bulk to the interface. In addition, the equilibrium constant for the oxygen adsorption at an interface due to the interfacial tension effect increases the oxygen content in the sub-interface region.
