OBJECTIVE To characterise the population that presents to the Accident and Emergency Centre (AEC) at Komfo Anokye Teaching Hospital (KATH) and to identify risk factors associated with bypassing proximal care facilities. METHODS A structured questionnaire was verbally administered to patients presenting to the AEC over 2 weeks. The questionnaire focused on the use of health care resources and ...

Programmed translational bypassing is a process whereby ribosomes "ignore" a substantial interval of mRNA sequence. Although discovered 25 y ago, the only experimentally confirmed example of this puzzling phenomenon is expression of the bacteriophage T4 gene 60. Bypassing requires translational blockage at a "takeoff codon" immediately upstream of a stop codon followed by a hairpin, which cause...

Nowadays, since wireless sensor networks (WSN)s are increasingly being used in challenged environments such as underground mines, tunnels, oceans and the outer space, fault-tolerance need has become a major requirement for routing protocols. So far, the proposed fault-tolerance methods or algorithms aim to recover the isolated failures which occur different parts of the network in different tim...

Recently, a model of the flux of amino acids through transfer RNAs (tRNAs) and into protein has been developed. The model predicts that the charging level of different isoacceptors carrying the same amino acid respond very differently to variation in supply of the amino acid or of the rate of charging. It has also been shown that ribosome bypassing is specifically stimulated at 'hungry' codons ...

In this paper we present a high performance cache replacement algorithm called Dueling Segmented LRU replacement algorithm with adaptive Bypassing (DSB). The base algorithm is Segmented LRU (SLRU) replacement algorithm originally proposed for disk cache management. We introduce three enhancements to the base SLRU algorithm. First, a newly allocated line could be randomly promoted for better pro...

Digital multipliers are among the most critical arithmetic functional units. The overall performance of these systems depends on the throughput of the multiplier. Meanwhile, the negative bias temperature instability effect occurs when a pMOS transistor is under negative bias (Vgs= −Vdd), increasing the threshold voltage of the pMOS transistor, and reducing multiplier speed. A similar phenomenon...

This paper investigates individuals' bypassing behavior in the health sector in Chad and the determinants of individuals' facility choice. We introduce a new way for measuring bypassing which uses the patients' own knowledge of alternative health providers available to them, instead of assuming perfect information as previously done. We analyze how objective and perceived health care quality an...

The design of an effective last level cache(LLC) continues to be an important issue in processor‘s performance. Recent works on high performance caches have shown that cache bypassing is an effective technique to enhance the performance of last level caches. However, commonly used inclusive cache hierarchy cannot benefit from this technique because bypassing inherently breaks the inclusion prop...
