Operator splitting for nonautonomous delay equations [PDF]

open access: yes, 2012
We provide a general product formula for the solution of nonautonomous abstract delay equations. After having shown the convergence we obtain estimates on the order of convergence for differentiable history functions. Finally, the theoretical results are

When Does a Mixture of Products Contain a Product of Mixtures? [PDF]

open access: yes, 2014
We derive relations between theoretical properties of restricted Boltzmann machines (RBMs), popular machine learning models which form the building blocks of deep learning models, and several natural notions from discrete mathematics and convex geometry.

Mathematical Model of Egg Production

open access: yesPoultry Science, 1971
Abstract EGG production in poultry is a complex quantitative trait showing considerable variation over time within the production period of a hen. Several methods of expressing egg production and its component characters (age at first egg, broodiness, egg production during different periods of the total production period, etc.) which apparently ...
