Task synchronization means that each redundant module has the same executing schedule in each task scheduling cycle of the operating system in the Triple Modular Redundancy (abbreviated TMR) fault-tolerant systems; it faces how to realize the coordination among the three modules. Therefore, it is necessary to investigate the task synchronization process of the TMR fault-tolerant system. In the ...

Dairy cow performance is affected by both the nutritional composition and physical structure of diet. The total mixed rations (TMR) largely depends on ingredient forage, dry matter (DM) content, mixing time type mixer used. This study investigated feed intake, eating time, milk production, DM digestibility, ruminal pH, budget, sorting antagonistic behaviours in lactating dairy cows fed grass/cl...

Widespread application of magnetic tunnel junctions (MTJs) for information storage has so far been limited by the complicated interplay between tunnel magnetoresistance (TMR) ratio and the product of resistance and junction area (RA). An intricate connection exists between TMR ratio, RA value and the bandgap and crystal structure of the barrier, a connection that must be unravelled to optimise ...

The bias dependence of the tunnel magnetoresistance TMR of Fe/MgO/Fe tunnel junctions is investigated theoretically with a fully self-consistent scheme that combines the nonequilibrium Green’s-function method with density-functional theory. At voltages smaller than 20 mV the I-V characteristics and the TMR are dominated by resonant transport through narrow interface states in the minority-spin ...

SRAM-based FPGAs are sensitive to radiation effects. Soft errors can appear and accumulate, potentially defeating mitigation strategies deployed at the Application Layer. Therefore, Configuration Memory scrubbing is required to improve radiation tolerance of such FPGAs in space applications. Virtex FPGAs allow runtime scrubbing by means of dynamic partial reconfiguration. Even with scrubbing, i...

We present a novel method that predicts transmembrane domains in proteins using solely information contained in the sequence itself. The PRED-TMR algorithm described, refines a standard hydrophobicity analysis with a detection of potential termini ('edges', starts and ends) of transmembrane regions. This allows one both to discard highly hydrophobic regions not delimited by clear start and end ...

In bit-patterned media recording (BPMR) channels, the inter-track interference (ITI) is extremely severe at ultra high areal densities, which significantly degrades the system performance. The partial-response maximum-likelihood (PRML) technique that uses an one-dimensional (1D) partial response target might not be able to cope with this severe ITI, especially in the presence of media noise and...

Fe/MgO/Fe magnetic tunnel junctions (MTJs) have been reported to have very high tunnel magnetoresistance (TMR) ratios. In this work, we present the results of First Principle simulations of Fe/ MgO/Fe MTJs with LSDA as the exchange correlation. The I-V characteristics in the antiparallel magnetization state exhibit strong features. The bias dependence of the TMR ratio shows nearly 100% TMR rati...

Clinical experience with transmyocardial laser revascularization has increased significantly over the last few years. Since several transmyocardial laser revascularization studies reported an apparent effect on the relief of angina and the FDA approved reimbursement of transmyocardial laser revascularization procedures in the USA, thousands of patients have been treated worldwide with different...

the effects of monesin and propylene glycol on feed intake, milk production, and composition as well as some blood metabolites of 16 primiparous and multiparous holstein lactating cows (60±30 days in milk (dim), milk production of 33±3 kg/day) were evaluated. cows were experimentally in a arranged in a randomized complete block design of: 4 feeding treatments, and 2 blocks of either primiparous...
