In this paper, we propose a new method for decomposing pattern classification problems based on the class relations among training data. By using this method, we can divide a K-class classification problem into a series of ((2)(K)) two-class problems. These two-class problems are to discriminate class Ci from class Cj for i=1, ..., K and j = i+1, while the(More)
Locomotion involves repetitive movements and is often executed unconsciously and automatically. In order to achieve smooth locomotion, the coordination of the rhythms of all physical parts is important. Neurophysiological studies have related that basic rhythms are produced in the spinal network called, the central pattern generator (CPG), where some neural(More)
The clinical efficacy of gefitinib, a tyrosine kinase inhibitor of epidermal growth factor receptor (EGFR), on brain metastases (BMs) from non-small-cell lung cancer (NSCLC) was evaluated. Fifteen patients with recurrent NSCLC with metastasis to the brain were treated with gefitinib. The objective tumor response rate (60%; 9 of 15 patients) for BM was the(More)
RATIONALE The diagnosis of Mycobacterium avium-complex pulmonary disease (MAC-PD) and/or its discrimination from pulmonary tuberculosis (TB) is sometimes complicated and time consuming. OBJECTIVES We investigated in a six-institution multicenter study whether a serologic test based on an enzyme immunoassay (EIA) kit was useful for diagnosing MAC-PD and(More)
We introduce and study the notion of shuue residual of a language L: the set containing the words whose shuue with L is completely included in L. Several properties and a characterization of the shuue residual of a language are obtained. The shuue closure of a language L (the smallest language that is shuue closed and contains L) is investigated. Moreover,(More)
Alternative Ways To Conceptualize Ideas Like WolframS Nks Although there are some books dealing with algebraic theory of automata, their contents consist mainly of Krohn-Rhodes theory and related topics. The topics in the present book are rather different. For example, automorphism groups of automata and the partially ordered sets of automata are(More)
We studied the relationship between physiologic parameters in cardiopulmonary exercise testing (CPET) and prognosis in terms of survival time in patients with chronic obstructive pulmonary disease (COPD) in order to accurately assess the severity of the disease. From a group of 195 patients with COPD who had consecutively undergone CPET between July 1989(More)
