Evaluation of error probability based on the assumption that the gains of APDs used in upper and lower branches of optical code-division multiple-access (OCDMA) systems are matched provides an approximation which may in practice be an overestimate or underestimate of the actual probability of error. In this paper, we analyze the impact of APD mismatch in a synchronous OCDMA system based on the ...

BACKGROUND Both vascular and compression etiologies have been proposed as the source of neurologic symptoms in tarsal tunnel syndrome. Advancing the understanding of the arterial anatomy supplying the posterior tibial nerve (PTN) and its branches may provide insight into the cause of tarsal tunnel symptoms. The purpose of this study was to describe the arterial anatomy of the PTN and its branch...

``Gardening'' of denuded coral reef habitats is a novel restoration approach in which sexual and asexual recruits are used. The present study aimed at the evaluation of the potentiality for restoration use of different types of small fragments subcloned from the Red Sea coral species Stylophora pistillata. In situ short-term (24 h, Ca method) and long-term (1 year, alizarin Red S vital staining...

Several top down proof procedures are presented in the literature for query answering in deductive databases using lemmatization. However, all of these mechanisms suuer from recomputation whenever more general queries than the lemmatized ones appear. We introduce a lemmatization mechanism for top-down evaluation that overcomes the problem by recording with the lemmas which branches of the searc...
