Abstract In the current century, sustainable production of agricultural products is one main challenges facing humanity. The amount water consumption, energy, and net income as important components sustainability systems special priority importance. This study used linear multi-objective programming models with aim maximizing five indicators cost efficiency (CE), irrigation (IE), energy product...
Highlights The article presents the latest data on techniques of implantation mitral homograft in tricuspid position, and identifies groups patients who are best suited for this method. Moreover, describes evolution type replacement, highlights that many surgical techniques, although justified, require further study to show demonstrate their advantages. Abstract Despite general trend cardiac su...
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...
Lost productivity is often excluded from economic evaluations, which may lead to an underestimation of the societal benefits of treatment. However, there are multiple challenges in reliably estimating and reporting productivity losses. This article explores the main challenges, ie, selecting an appropriate valuation method (ie, human capital, friction cost, or multiplier), avoiding double count...
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 ...
This paper introduces the hierarchical interpolative factorization for integral equations (HIF-IE) associated with elliptic problems in two and three dimensions. This factorization takes the form of an approximate generalized LU decomposition that permits the efficient application of the discretized operator and its inverse. HIF-IE is based on the recursive skeletonization algorithm but incorpo...
BACKGROUND A higher energy cost of walking poststroke has been linked to reduced walking performance and reduced participation in the community. OBJECTIVE To determine the contribution of postintervention improvements in walking speed and spatiotemporal gait asymmetry to the reduction in the energy cost of walking after stroke. METHODS In all, 42 individuals with chronic hemiparesis (>6 mon...
