1.2 Machine failure A system is composed of 5 components, each of which is either working or broken. Consider an experiment that consists of observing the status of each component, and let the outcome of the experiment be given by the vector (x1, x2, x3, x4, x5), where xi = 1 if component i works and 0 if component i is broken. 1. How many outcomes are in the sample space of this experiment? 2....

Neoplastic transformation is a complex process that results from multiple changes in gene activities. Probably most of these are mutational, i.e. alterations in the genomic structure of DNA, but others may be due to adaptive changes wherein genes are expressed that are inappropriate to a stage of development or differentiation. In this commentary neoplastic development is discussed in the conte...

le mouvement transversal de la locomotive ou des wagons , appele ie lacet, provient de deux causes principales: -la conicite des bandages -les irregularites de la voie dans ie plan horizontal. on se propose ici d'etudier la premiere cause , ce qui nous conduit a une equation differentielle non lineaire du deuxieme ordre. • l'equation en question est etudiee dans plusieurs cas difftten...

We design and release BONIE, the first open numerical relation extractor, for extracting Open IE tuples where one of the arguments is a number or a quantity-unit phrase. BONIE uses bootstrapping to learn the specific dependency patterns that express numerical relations in a sentence. BONIE’s novelty lies in task-specific customizations, such as inferring implicit relations, which are clear due ...

The South African real estate industry contributes to job creation, economic development and poverty eradication (Estate Agency Affairs Board [EAAB], 2020). However, it is challenged by unethical, unregistered, non-complying property practitioners firms (EAAB, 2018). Moreover, some have inefficient systems that fail combat hacking cybercrime (Jardine, 2015). Although strategies in place, there ...

conclusions endocarditis is an important disease with a high mortality rate if not treated appropriately. therefore, these patients need more attention. in echocardiography, vegetation and complications of ie such as abscess and paravalvular leakage can be detected. results we studied 35 patients, 45% male and 55% female with a mean age of 56.36 ± 12.44 years. fever (80%) and chills (65.7%) wer...

BACKGROUND In March 2008, the National Institute for Health and Care Excellence recommended stopping antibiotic prophylaxis (AP) for those at risk of infective endocarditis (IE) undergoing dental procedures in the United Kingdom, citing a lack of evidence of efficacy and cost-effectiveness. We have performed a new economic evaluation of AP on the basis of contemporary estimates of efficacy, adv...
