The high-performance, scalability and miniaturization requirements together with the power, mass and cost constraints mandate the use of commercial-off-the-shelf (COTS) components and standards in the X2000 avionics system architecture for deep-space missions. In this paper, we report our experiences and findings on the design of an IEEE 1394 compliant fault-tolerant COTS-based bus architecture...

BACKGROUND Acyl-COA:cholesterol acyltransferase (ACAT) converts cholesterol to cholesteryl esters. The form of ACAT in macrophages, ACAT1, contributes to foam cell formation in the arterial wall and the development of atherosclerosis. Recent studies in a mouse model of atherosclerosis (the apolipoprotein E [apoE]-deficient mouse), however, have suggested that complete deficiency of ACAT1 activi...

The Network Of Workstations (NOWs) is the trend for distributed computing, and the costeffectiveness of networking system is one of the key issues for NOWs. The IEEE 1394 bus can be a cost-effective solution for linking a network of computers, in this paper, we tested the performance of IEEE 1394 on the Linux system, and discussed how to improve the IEEE 1394 performance towards cluster computi...

Recently, we have begun to see a convergence of traditional network and bus technologies. The IEEE-1394 Serial Bus Protocol (FireWire) is a good example of this convergence, targeting the interconnection of consumer electronics, computers, and peripheral devices. IEEE 1394 provides for a high-speed, plug-and-play, peer-to-peer interconnect supporting both asynchronous and isochronous traffic. I...

This paper investigates the behavior of the IEEE 1394 bus in the presence of transient errors in the hardware layers of the protocol. Software-implemented error injection is used to introduce errors into the internals of the 1394 bus hardware chipset. Results from this study indicate that the IEEE 1394 bus protocol provides robust network communication in the presence of single-bit errors in th...

In the future digitalized life, both of IEEE 1394 and IEEE 802.3 protocols will be very important and widely applied. The former is adopted by all kinds of digital multimedia devices to obtain high-speed transmissions. The later has been often adapted to construct LANs, and will be popularized to construct WANs. Thus, it is an important issue to simplify the design flow and reduce the time-to-m...

Previous studies have indicated that men and women have different amygdala responses to novel (vs familiar) and valenced (positive vs negative) material. It is not known, however, whether these affective sex differences are related. In this study, we tested whether women have more persistent amygdala responses to familiar, negative material than men do. During fMRI, male and female participants...

The acyl-CoA:cholesterol acyltransferase (ACAT) enzyme is thought to be responsible for foam cell formation and the subsequent progression of atherosclerosis. The apolipoprotein E and low density lipoprotein receptor double knockout (apoE/LDLr-DKO) mouse is an animal model that develops severe hyperlipidaemia and atherosclerosis. Here we have examined the effect of oral administration of an ACA...

Following traumatic spinal cord injury, acute demyelination of spinal axons is followed by a period of spontaneous remyelination. However, this endogenous repair response is suboptimal and may account for the persistently compromised function of surviving axons. Spontaneous remyelination is largely mediated by Schwann cells, where demyelinated central axons, particularly in the dorsal columns, ...
