The polyhedral homotopy continuation method is known to be a successful method for finding all isolated solutions of a system of polynomial equations. PHoM, an implementation of the method in C++, finds all isolated solutions of a polynomial system by constructing a family of modified polyhedral homotopy functions, tracing the solution curves of the(More)
The SDPA-M (Semidfinite Programming Algorithm in MATLAB) Version 2.0 is a MATLAB interface of the SDPA Version 6.0 [2], which is known as a fast and numerically stable solver for SDPs (semidefinite programs) [4, 5]. The SDPA-M inherits various features from the SDPA. Particularly, the SDPA-M can read SDPA dense and sparse format input data files of SDPs. In(More)
The ultrastructural changes seen in muscle fibres of aged rats have been studied and described in relation to the degree of fibre atrophy and to the involvement of the different fibre types. The ultrastructural abnormalities were classified into four different categories: (1) diffuse dilatation of sarcoplasmic reticulum, (2) streaming of Z-bands, (3)(More)
Clinical phenotypes of hereditary diffuse leukoencephalopathy with spheroids (HDLS), a familial progressive neurodegenerative disorder affecting the white matter of the brain, are heterogenous and may include behavioral and personality changes, memory impairment, parkinsonism, seizure, and spasticity. Thus, HDLS is frequently unrecognized and misdiagnosed.(More)
BACKGROUND Some 200 patients, including those with Alzheimer's disease and other types of dementia, stay year-round in Yokohama - Houyuu Hospital. They undergo computed tomography (CT) neuroradiological examination at least once or twice a year. For this study, the accumulative data, including clinical and neuroradiological, were analyzed. METHODS(More)
An epidemic of viral hepatitis was studied in the Okitsu area of Shimizu city in Japan from April 1980 to November 1981. One hundred thirty-six serum samples from patients with viral hepatitis were tested for hepatitis B virus, hepatitis A virus, Epstein-Barr virus, and cytomegalovirus infection. Immunoserological data showed the outbreak of viral hepatitis(More)
