OBJECTIVE To examine the prevalence of mutations in spinocerebellar ataxia (SCA) genes in patients who were clinically diagnosed with multiple system atrophy (MSA). METHODS Genetic tests for SCA were performed in 302 of 528 patients who met the diagnostic criteria for MSA based on clinical features. Generally, when a patient had cerebellar symptoms or(More)
—One of the most important problems in the field of performance optimization for data networks is the problem of routing to achieve delay minimization. This becomes extremely important in the context of providing Quality of Service while satisfying demand. The problem is classical and was considered three decades ago by a number of authors primarily(More)
In this paper, we consider security aspects of network routing in a game-theoretic framework where an attacker is empowered with an ability for intrusion into edges of the network; on the other hand, the goal of designer is to choose routing paths. We interpret the secure routing problem as a two player zero sum game. The attacker can choose one or more(More)
