This paper is motivated by the industrial research problem of designing a real-world recommender system for a large Information Technology (IT) company. Given historical records of client purchases, compactly represented as a sparse client-times-product “who-bought-what” binary matrix, the goal is to build a model that provides recommendations for what products should be sold next to the existi...

This paper investigates Monte Carlo techniques for construction of compact wavefunctions for the internal atomic motion of the D 3 O + ion. The polarization force field models of Stillinger, et al. and of Ojamae, et al. were used. Initial pair product wavefunctions were obtained from the asymptotic high temperature many-body density matrix after contraction to atom pairs using Metropolis Monte ...

the effects of dietary inclusion of medicinal plants’ by-product mixture on performance, the relative internal organ weight, ileal microbial counts, and small intestinal and liver morphologic alterations in laying hens receiving different omega-6 to omega-3 ratios as a 2×3 factorial arrangements with three levels of plants’ by-product (zero, 2.5 and five percent) and two omega-6 to omega-3 rati...

Let X be a smooth projective variety. Using modified psi classes on the stack of genus zero stable maps to X, a new associative quantum product is constructed on the cohomology space of X. When X is a homogeneous variety, this structure encodes the characteristic numbers of rational curves in X, and specialises to the usual quantum product upon resetting the parameters corresponding to the modi...
