Aim of the study: The effects forage source (alfalfa hay; AH vs. wheat straw; WS) with rumen undegradable to degradable protein ratio [low (LR) = 28:72; high (HR) 36:64] were evaluated in young dairy calves.Area Arak, Iran.Material and methods: Forty-eight 3-d old female Holstein calves (44.5 kg BW) allocated four treatments: (1) low dietary RUP:RDP (AH-LR); (2) (AH-HR); (3) WS (WS-LR); (4) (WS...

increases with more disks in the array (at a minimum, catastrophic data loss is twice as likely compared to single drives without RAID). A single disk failure destroys the entire array because when data is written to a RAID 0 volume, the data is broken into fragments called blocks. The number of blocks is dictated by the stripe size, which is a configuration parameter of the array. The blocks a...

Summary: A major challenge in mass-spectrometry-based proteomics is the peptide identification statistics problem. As a tool designed to tackle this issue, RAId deNovo can generate, for a given tandem mass spectrum, the score distribution resulting from scoring all possible peptides under a certain class of scoring functions. This valuable information may aid development of a better measure for...

Disk arrays (RAID) have been proposed as a possible approach to solving the emerging I/O bottleneck problem. The performance of a RAID system when all disks are operational and the MTTF,,, (mean time to system failure) have been well studied. However, the performance of disk arrays in the presence of failed disks has not received much attention. The same techniques that provide the storage effi...

Deploying solid state drives (SSDs) in RAID configurations can leverage the performance of persistent storage systems into a new dimension. However, the Achilles’ heel of SSDs and, therefore, also SSD RAIDs is their write performance, especially for small random requests. To prevent a degradation of the write throughput, it is important to maintain an adequate amount of free flash capacity. Thi...

Due to recent advances in CPU and memory system performance, I/O systems are increasingly limiting the performance of modern computer systems. Redundant Arrays of Inexpensive Disks (RAID) have been proposed by Patterson et al. [1] to meet the impending I/O crisis. RAIDs substitute many small inexpensive disks for a few large expensive disks to provide higher performance (both transfer rate and ...
