Although the enantiomers of GFX show similar levels of antimicrobial activity and pharmacokinetics[2], the other biological activities (i.e., toxicity or enantioselective recognition to various receptors in vivo) of GFX enantiomers have not yet been studied. With this in mind, we developed a rapid and cost-effective high performance liquid chromatographic (HPLC) separation procedure for GFX enantiomers with a pre-column esterification strategy.展开更多

(2) Using deletion strategy, both positive unit lock resolution and input lock resolution are complete for a Horn set where the indexes of positive literals are greater than those of negative literals.

Gerontocracy, governance by the elderly, an adopted mode of government by most African communities, mostly has its wisdom reflected in proverbs. Proverbs then become an administrative tool to resolve conflict among warring parties, communities or persons. In this paper, one of the objectives is to showcase instances of proverbs serving as tools for conflict resolution in D.O. Fagunwa's Yoruba novel entitled Ogboju Ode Ninu Igbo IrunmQl~, which Abioye (1989) has translated as Le preux chasseur dans la for^t infest^e de demons (The Forest of a Thousand Demons). Another objective is to study the translational strategies employed by Abioye to successfully translate the rich cultural African worldview encapsulated in Yoruba proverbs into French, a non-African language.展开更多

In this model, distributed learning agents with diverse classifiers, detect sensorstream data, make local predictions, communicate and collaborate to identify current activities.Then, they learn from their collaborations to improve their own performance in activity recognition.Conflict resolution strategies are applied to generate one final predicted activity when thelocal predicted activity of an agent is different from received predicted activities of other agents.In this paper, two conflict resolution strategies using online learning, w-max-trust and w-maxfreq,are proposed. We experimentally test these strategies by performing an evaluation studyon the Aruba dataset. The obtained results indicate an enhancement in terms of accuracy and Fmeasuremetrics compared to the offline strategies max-trust and max-freq and also to the onlineexisting one max-wPerf .展开更多
