This paper proposes an evaluation result of a high security distribution and rake technology for realizing disaster recovery. In an experimental evaluation, the encryption and spatial scrambling performance and the average response time have been estimated in terms of the file data size. Discussion is also provided on an effective shuffling algorithm to(More)
Extracellular fluid levels of noradrenaline (NA) in the locus coeruleus (LC) during naloxone-precipitated morphine withdrawal with pretreatment of yohimbine (1 mg kg (-1), s.c.) or clonidine (1 mg kg (-1), s.c.) were measured in rats. There was a significant increase in the NA level after the injection of naloxone (2 mg kg (-1), i.p.) in the(More)
—A practical mechanism for a file-backup system concept is proposed. In this paper, it is demonstrated that a highly secure file backup mechanism can be achieved by combining technologies that implement the following: spatial random scrambling of file data, subsequent random fragmentation of the file, the duplication and encryption of each file fragment(More)
An innovative mechanism of a file-backup system concept is proposed. In the proposed file backup mechanism, the combination of the following technologies such as a spatial random scrambling of file data, a subsequent random fragmentation of the file, the corresponding encryption and duplication for each fragmented one by using a stream cipher code in each(More)
Effects of azelnidipine were examined and compared with those of amlodipine on stunned myocardium in dogs. The left anterior descending (LAD) coronary artery was ligated for 20 min and subsequently released for 60 min. A vehicle, azelnidipine (0.3 mg/kg), or amlodipine (0.3 or 1 mg/kg) was injected intravenously 20 min before LAD ligation. The heart rate(More)
