Introduction: In today's world, “It is believed that use of microbial agents and biological toxins are harmful for human health. Food industry is a soft target and potentially vulnerable to deliberate contamination. The manufacturing units of dairy industry are a good example. The purpose of this study was to determine the level of food defense preparedness of dairy production units using FDA F...

Abstract BACKGROUND A newly developed brain molecular marker (BMM) data item was implemented by U.S. cancer registries for individuals diagnosed with tumors in 2018—including IDH and 1p/19q-codeletion statuses adult-type diffuse gliomas. We thus investigated the testing/reporting completeness of BMM METHODS Cases histopathologically-confirmed glioblastoma, astrocytoma, oligodendroglioma 2018 we...

This paper studies a reliable facility location problem with facility protection that aims to hedge against random facility disruptions by both strategically protecting some facilities and using backup facilities for the demands. An Integer Programming model is proposed for this problem, in which the failure probabilities of facilities are site-specific. A solution approach combining Lagrangian...

— We treat a discrete uncapacitated facility location problem where the installation cost per facility is a gênerai nonlinear function of the number of established facilities. Assuming a convexity proper ty, Mirchandani and Jagannathan developed a heur is tic solution procedure for this problem. Hère, we show how to modify their algorithm in order to get and prove exact solutions and, at the sa...

Matrix Factorization (MF) is one of the most successful Collaborative Filtering (CF) techniques used in recommender systems due to its effectiveness and ability deal with very large user-item rating matrix. However, when matrix sparseness increases performance deteriorates. Expanding MF include side-information users items has been shown by many researchers both improve general recommendation h...
