The von Economo neurons (VENs) are large bipolar neurons located in frontoinsular (FI) and anterior cingulate cortex in great apes and humans, but not other primates. We performed stereological counts of the VENs in FI and LA (limbic anterior, a component of anterior cingulate cortex) in great apes and in humans. The VENs are more numerous in humans than in(More)
Extensive work has been done for optimal management of scratch-pad memory (SPM) all assuming that the SPM is assigned a fixed address space. The main target objects to be placed on the SPM have been code and global memory since their sizes and locations are not changed dynamically. We propose a novel idea of dynamic address mapping of SPM with the(More)
The claustrum and the insula are closely juxtaposed in the brain of the prosimian primate, the gray mouse lemur (Microcebus murinus). Whether the claustrum has closer affinities with the cortex or the striatum has been debated for many decades. Our observation of histological sections from primate brains and genomic data in the mouse suggest former. Given(More)
Major Depressive Disorder (MDD) is associated with impaired processing and regulation of emotions. A vast body of research has elucidated the altered neural processes that occur in response to emotional stimuli, while little is known about anticipatory processes. Here we used functional magnetic resonance imaging (fMRI) to investigate neural activation(More)
In this paper, we propose a timestamp series approach to defend against Sybil attack in a vehicular ad hoc network (VANET) based on roadside unit support. The proposed approach targets the initial deployment stage of VANET when basic roadside unit (RSU) support infrastructure is available and a small fraction of vehicles have network communication(More)
A vehicular ad hoc network (VANET) allows vehicles to share traffic information and to alert each other of emergency events. To achieve this goal, a security mechanism must be designed to guarantee that no malicious vehicles can intercept, manipulate, or modify the traffic information without being detected. In this paper, we present two novel approaches to(More)
The von Economo neurons (VENs) are large bipolar neurons located in the frontoinsular cortex (FI) and limbic anterior (LA) area in great apes and humans but not in other primates. Our stereological counts of VENs in FI and LA show them to be more numerous in humans than in apes. In humans, small numbers of VENs appear the 36th week postconception, with(More)
In this paper we propose a dynamic code overlay technique of synchronous data-flow (SDF) –modeled program for low-end embedded systems which lack MMU-support. With this technique, the system can utilize expensive SRAM memory more efficiently by using flash memory as code storage. SRAM is divided into several regions called overlay slots. A data-flow block(More)
OBJECTIVES To evaluate the risk of fractures related with zolpidem in elderly insomnia patients. METHODS Health claims data on the entire South Korean elderly population from January 2005 to June 2006 were extracted from the Health Insurance Review and Assessment Service database. We applied a case-crossover design. Cases were defined as insomnia patients(More)
