OBJECTIVE The purpose of this study was to evaluate and compare the rate of bacterial contamination of reused and new unused burs after different sterilization sessions. MATERIALS AND METHODS The test group consisted of 40 used fissure burs, and the control group of 40 unused new fissure burs (total n = 80). The burs from both groups were precleaned according to standard protocols and then su...

Proteins share similar segments with one another. Such "reused parts"-which have been successfully incorporated into other proteins-are likely to offer an evolutionary advantage over de novo evolved segments, as most of the latter will not even have the capacity to fold. To systematically explore the evolutionary traces of segment "reuse" across proteins, we developed an automated methodology t...

The capability of e ciently recognizing reused functions for binary code is critical to many digital forensics tasks, especially considering the fact that many modern malware typically contain a signi cant amount of functions borrowed from open source software packages. Such a capability will not only improve the e ciency of reverse engineering, but also reduce the odds of common libraries lead...

Abstract Several marble slabs fashioned like game boards for XII scripta/Alea come from Christian catacombs in Rome. Often deliberately cut or fragmented, they were used as funeral slabs. The general opinion is that these have found a secondary use the context. present paper presents critical discussion of this interpretation. differ several details real boards. Moreover, inscriptions often bet...

| This study investigated the efficiency of the previously used controlled internal drug release (CIDR) stored for 30 days before reusing. In the first experiment, twenty seven Holstein cows at the day of estrus (day 0) received either no treatment (control), new or reused CIDR and blood samples were collected at day 0, 1, 3 and 7. At day 1 and 3, serum progesterone concentration in cows receiv...

In this paper, novel hybrid MOSFET(HMOS) structure has been proposed to reduce the gate leakage current drastically. This novel hybrid MOSFET (HMOS) uses source/drain-to-gate non-overlap region in combination with high-K layer/interfacial oxide as gate stack. The extended S/D in the non-overlap region is induced by fringing gate electric field through the high-k dielectric spacer. The gate leak...
