There are numerous emerging nonvolatile memory technologies, which have been proposed as being capable of replacing hard disk drives (HDDs). In this paper, the prospects for these alternative technologies to displace HDDs in 2020 are analyzed. In order to compare technologies, projections were made of storage density and performance in year 2020 for both(More)
In this work, Android operating system based robot platform and smart phone operated control and monitoring system are introduced. To implement this work, Cortex-A8 series S5PV210 embedded processor and Android operating system are correlated. The robot has an autonomous and manual travel and is controlled by only smart phone. In the Android OS (Operating(More)
Context-aware applications can satisfy users' information needs without consuming too much time in discovering information adaptive to users. In this paper, we propose a personalized information system to provide more user-oriented information considering context information such as a personal profile with preferences, location, traffic condition, weather,(More)
The orphan nuclear hormone receptor SHP has been proposed to have a key role in the negative feedback regulation of bile acid production. Consistent with this, mice lacking the SHP gene exhibit mild defects in bile acid homeostasis and fail to repress cholesterol 7-alpha-hydroxylase expression in response to a specific agonist for the bile acid receptor(More)
Contrast in optical coherence tomography (OCT) images can be enhanced by utilizing surface plasmon resonant gold nanoparticles. To improve the poor in vivo transport of gold nanoparticles through biological barriers, an efficient delivery strategy is needed. In this study, the improved penetration and distribution of gold nanoparticles were achieved by(More)
Gold nanoparticles provide an attractive and applicable scaffold for delivery of nucleic acids. In this review, we focus on the use of covalent and noncovalent gold nanoparticle conjugates for applications in gene delivery and RNA-interference technologies. We also discuss challenges in nucleic acid delivery, including endosomal entrapment/escape and active(More)
It is important to use a better criterion in selection and discretization of attributes for the generation of decision trees to construct a better classifier in the area of pattern recognition in order to intelligently access huge amount of data efficiently. Two well-known criteria are gain and gain ratio, both based on the entropy of partitions. We propose(More)
OBJECTIVE Rapid eye movement sleep behavior disorder (RBD) is associated with α-synucleinopathies, such as Parkinson's disease (PD). We aimed to assess the differences in the clinical characteristics of PD with and without RBD. METHODS Forty-two patients previously diagnosed with PD were evaluated for clinical history, motor and cognitive functioning(More)
