Bulk U(1) Messenger

We propose a new U(1) gauge interaction in the bulk in higher dimensional spacetime, which transmits supersymmetry-breaking effects on the hidden brane to the observable our brane. We find that rather small gauge coupling constant of U(1)_{bulk}, $\alpha_{bulk} \simeq 5 \times 10^{-4}$, is required for a successful phenomenology. This result implies the compactification length $L$ of the extra dimension to be $L^{-1} \simeq 2 \times 10^{15}GeV$ for (4+1)-dimensional spacetime. This large compactification length $L$ is a crucial ingredient to suppress unwanted flavor-changing neutral currents and hence our proposal is very consistent with the Randall-Sundrum brane-world scenario.Comment: 9 pages, Late

初診時に膀胱刺激症状のみを訴えたループス膀胱炎の1例

37歳女性.患者は重度の膀胱刺激症状のみを主訴とし受診, 膀胱生検で粘膜下の炎症と血管炎の所見を認めた.血液データより自己免疫疾患が疑われたため, 更に検査を追加したところSLE(全身性エリテマトーデス)およびループス膀胱炎と診断された.治療として早期のステロイド投与を行なったところ重度の膀胱刺激症状は軽快したCystitis related with systemic lupus erythematosis (SLE) is termed as lupus cystitis. It is a subtype of SLE in which gastrointestinal and bladder symptoms are prominent and it usually manifests with other symptoms of SLE. We present a case in a 37-year-old woman whose sole complaint was the severe urinary symptoms. A biopsy of the bladder showed inflammation in the submucosa and the finding of vasculitis. An autoimmune disease was suspected from the blood serum sample. A further laboratory study was performed and she was diagnosed with SLE and lupus cystitis. Prompt therapy with corticosteroids resulted in the improvement of the severe bladder symptoms

Posterior maxillary alveolar vertical distraction osteogenesis by bi-directional distractor

AbstractA patient with severe posterior maxillary hypoplasia was simulated using a 3-dimensional model by rapid prototyping, and segmental vertical distraction osteogenesis was planned to advance the posterior maxillary segment. The bi-directional distractor was adapted to the alveolar ridge and zygomatic buttress. After a 7-day latency period, we started distraction at a rate of 0.35mm every 12h. 12mm of advancement of the posterior maxillary segment was achieved. This distraction osteogenesis using a bi-directional distractor with proper therapeutic planning and good surgical technique will help ensure adequate vector control to predictably regenerate the hard and soft tissues during alveolar distraction

Comparison of crystal structures and effects of Co substitution in a new member of Fe-1111 superconductor family AeFeAsF(Ae = Ca and Sr): a possible candidate for higher Tc superconductor

We refined crystal structures of newly found members of the Fe-1111 superconductor family, CaFe\_{1-x}Co\_{x}AsF and SrFe\_{1-x}Co\_{x}AsF (x = 0, 0.06, 0.12) by powder synchrotron X-ray diffraction analysis. The tetragonal to orthorhombic phase transitions were observed at ~120 K for unsubstituted CaFeAsF and at ~180 K for unsubstituted SrFeAsF, the transition temperatures agreeing with kinks observed in temperature-dependent resistivity curves. Although the transition temperature decreases, the structural phase transitions were observed below 100 K in both samples of x = 0.06, and finally they were suppressed in the doping level of x = 0.12. The refined structures reveal that distortions of the FeAs4 tetrahedron from the regular tetrahedron likely originate from mismatches in atomic radii among the constituent elements. In this system, the enlarged FeAs4 tetrahedron resulting from larger radius of Sr than that of Ca is flattened along a-b plane, whereas the smaller radius of Ca makes the tetrahedron closer to regular one, and their characteristic shapes are further enhanced by Co substitution. These results suggest that the CaFeAsF compound is a promising candidate for higher-Tc superconductor.Comment: 17 pages, 8 figures, 2 tables, Supplementary information is included at the end of the documen

Web-based System for Designing Game-based Evacuation Drills

A game-based evacuation drill (GBED) using the program Real-World Edutainment is effective disaster education. For the successful GBED, an evacuation scenario and digital materials are important. We are developing a web-based system to design GBEDs through community survey, digital material creation and evacuation scenario composition. This system works with a standard web browser and allows a wide range of people to participate in the GBED design process through simple operations

Osteosynthesis for Geriatric Acetabular Fractures: An Epidemiological and Clinico-Radiological Study Related to Marginal or Roof Impaction

This retrospective study sought to elucidate the incidence rates of roof impaction (RI) and marginal impaction (MI) and radiological and clinical outcomes of open reduction and internal fixation (ORIF) for RI and MI in geriatric acetabular fractures. The cases of 68 patients aged ≥ 65 years (mean 71 years) treated with ORIF were analyzed. MI was present in 12 fractures (67%) and an RI of the weight-bearing surface was present in 24 (46%) of the potential fracture types. Regarding the reduction quality, 54% of the reductions were graded as anatomical, 37% as imperfect, and 9% as poor. In the clinical evaluations of the 45 patients who had > 1-year follow-up (follow-up rate: 66.2%), 18% were graded as excellent, 53% as good, 16% as fair, and 13% as poor. An anatomic reduction was strongly associated with good or excellent clinical and radiological outcomes. CT was superior to radiographs for detecting the residual displacement postoperatively. Postoperative deep infection occurred in four patients. Three patients (6.7%) underwent a total hip arthroplasty conversion due to secondary osteoarthritis of the hip. We recommend ORIF as the preferred surgical treatment option for displaced acetabular fractures in elderly patients
