Background Disorders of circadian rhythms in the production inflammatory mediators play an important role pathogenesis rheumatoid arthritis (RA) [1]. Innate immune factors, particular toll-like receptors 2 (TLR2), are involved formation pattern RA. Recently was shown that TLR2 development atherosclerosis and hypertension [2]. Chronobiological aspects innate immunity, soluble form (sTLR2) RA its...

ÐThe performance of today's database systems is usually limited by the speed of their I/O devices. Fast I/O systems can be built from an array of low cost disks working in parallel. This kind of disk architecture is called RAID (Redundant Arrays of Inexpensive Disks). RAID promises improvement over SLED (Single Large Expensive Disks) in performance, reliability, power consumption, and scalabili...

Intergroup violence is common among humans worldwide. To assess how within-group social dynamics contribute to risky, between-group conflict, we conducted a 3-y longitudinal study of the formation of raiding parties among the Nyangatom, a group of East African nomadic pastoralists currently engaged in small-scale warfare. We also mapped the social network structure of potential male raiders. He...

RAID, a storage architecture designed to exploit I/O parallelism and provide data reliability, has been deployed widely in computing systems as a storage building block. In large scale storage systems, in particular, RAID-6 is gradually replacing RAID-5 as the dominant form of disk arrays due to its capability of tolerating concurrent failures of any two disks. MDS (maximum distance separable) ...

For the actual Video-On-Demand (VOD) service environment, we implement a cluster-based VOD server composed of general PCs and adopt the parallel processing for MPEG movies. For the implemented VOD server, a video block recovery mechanism is designed on the RAID-3 and the RAID-4 algorithms. However, without considering the architecture of cluster-based VOD server, the application of these basic ...

A constant intravenous infusion of phenylephrine (0.74 +/- 0.41 micrograms/kg/min) was given to 10 patients to cause a continuous augmentation in reflex vagal tone. After the infusion, the diastolic blood pressure increased from 76 +/- 7 to 89 +/- 11 mm Hg (p less than 0.01). The sinus cycle length and atrial-His (AH) interval were measured, and incremental atrial pacing was performed before an...

We found that a reliability model commonly used to estimate Mean-Time-To-Data-Loss (MTTDL), while suitable for modeling RAID 0 and RAID 5, fails to accurately model systems having a fault-tolerance greater than 1. Therefore, to model the reliability of RAID 6, Triple-Replication, or k-of-n systems requires an alternate technique. In this paper, we explore some alternatives, and evaluate their e...

the oldest works of muslim scholars in the fields of kalām , ḥadīth and tafsīr during the 2nd and 3rd centuries ah rarely offer an explicit basis for regarding the qur’ān as an inimitable miracle of the prophet. however, the issue appears fully fledged in the works of scholars such as al-bāqillānī, qāḍī ‘abd al-jabbār and al-sharīf al- murtaḍā. this silence in the early islamic centuries, when ...
