Working memory (WM) impairment has received attention as a behavioral characteristic of schizophrenia. Neurobiological studies have led to the hypothesis that a deficit in dopamine transmission through D1 receptors in the prefrontal cortex (PFC) is associated with WM impairment in schizophrenia. However, empirical approaches that aim to clarify the nature of the impairment and its underlying mechanism...
In this paper we consider the mean variance stochastic optimal control problem of discrete-time Markov jump with multiplicative noise linear systems. The performance criterion is to minimize the final variance subject to a restriction on the final expected value of the output, or to maximize the final expected value subject to a restriction on the final variance of the output of the system. We also...
This paper discusses the modern approach of the implementation of Software as a Service (SaaS) for NASA as a way to reduce cost and increase efficiency. The grid XML datastore framework is an extension of SaaS framework based on eXtensible Database technology (XDB). This is implemented to support the Innovative Partnership Program (IPP) for its Technology Transfer System (NTTS) project.
The purpose of this study was to evaluate the early MR appearances of the intervertebral disc obtained within 24h after percutaneous laser discectomy and to determine if a correlation exists between the MR images and the clinical outcome.Twenty-nine discs in 26 patients with contained lumbar disc herniation treated by laser were included. Laser intervention was performed using Ho:YAG laser system...
