[en] Anomalous Hall effect induced by a spin-polarized current in superconductors (SC) is theoretically studied. The spin-polarized quasiparticles flowing in SC are deflected by spin-orbit impurity scattering to create the charge accumulation in the transverse direction. Due to overall charge neutrality, a compensating change appears in the pair density of the condensate. To maintain the electrochemical potential of the condensate spatially constant, an electric field builds up in the transverse direction, yielding the Hall voltage. It is shown that the Hall voltages due to side jump and skew scattering have different temperature dependence in the superconducting state

[en] Investigations have been carried out to determine the number of cases examined for neurological disorders with CT. The studies revealed that the number of CT candidates increased from one to four cases per 1000 patients during a 3-year study beginning in 1973. This study also estimated that future case loads will increase to six cases per 1000 patients. Thus it can be expected that the number of CT candidates will rise dramatically, resulting in the appearance of reasonably priced CT units on the market

[en] In our department external irradiation is given priority over intracavitary (radium) therapy for the treatment of carcinoma of the cervix uteri. Our policy is to irradiate the volume containing the primary lesion, parametrium and pelvic lymph nodes to a dose of 40.0 Gy in about 4 weeks for stages I and IIa, or 50.0 Gy over 5 weeks for stages IIb and III. For stages I and IIa, intracavitary radium therapy is additionally given to a dose of 28.0-30.0 Gy at ''point A'', 7-10 days after the external irradiation, by means of two fractions with an interval of 7-10 days. For stages IIb and III, further external irradiation is carried out to give an additional dose of 20.0 to 25.0 Gy to the cervix and parametrium over 2 weeks by means of radiation fields of reduced size. If the size of the tumour in stages IIb and III is considerably reduced after the initial dose of 50.0 Gy, and the dose to point A is 40.0 Gy, intracavitary therapy is carried out without the additional small field irradiation. The intracavitary therapy is given twice with an interval of 8 days. For stage IV without distant metastases the treatment policy is the same as that in stage III; for stage IV with distant metastases, only whole pelvis irradiation is performed, to a dose of 50.0 Gy over 5 weeks

[en] We have developed a method of three-dimensional trajectory tracing with realistic magnetospheric models and compared the flow patterns of protons and electrons in two model magnetospheres. We estimated the pitch angle dependence of the trajectories of protons and compared the difference of the day-night asymmetries of flow patterns between these two models. We also estimated the effect of the corotating electric field on the trajectories of 1.0 keV electrons under the condition K_p = 0 model and obtained a significant difference between the trajectories with and without the corotating field at a distant region of the magnetosphere and discuss the existence limit of the corotating electric field relating with the trajectories

[en] Spin transport in a nonmagnetic metal connected to ferromagnetic injector and detector is theoretically studied. A general expression for spin accumulation signal, which covers from the metallic to the tunneling regime, is derived, and recent spin injection and detection experiments are analyzed. In a superconductor device, the spin accumulation signal is strongly enhanced because superconductors are low carrier systems for spin transport
