BackgroundThe postnatal intestinal colonization of human milk-fed and formula-fed infants differs substantially, as does the susceptibility to infectious diseases during infancy. Specific ingredients in human milk, such as prebiotic human milk oligos

In 2011-2012, a survey was performed in three regional hospitals in the Czech Republic to determine the incidence of Clostridium difficile infections (CDIs) and to characterize bacterial isolates. C. difficile isolates were characterized by PCR ribot

Objectives The aim of this study was to demonstrate suitability and safety of an infant formula enriched with α-lactalbumin with a reduced protein content of 1.89 g protein/100 kcal. Methods This was a randomized, double-blind controlled trial with

Eleven swarm-intelligence-based (SI) and bio-inspired (BI) algorithms are compared with four advanced adaptive differential evolution (DE) variants, the classic DE and the blind random search on two benchmark sets. One of the benchmark sets is the CE

A new mechanism for the adaptation of the population size in differential evolution (DE) is described. The adaptive mechanism is based on linear reduction of the population diversity and enables to decrease or increase the population size during the

New variants of the adaptive competitive differential evolution algorithm are proposed and tested experimentally on the CEC 2013 test suite. In the new variants, the adaptation is based on the competition of several strategies. The current-to-pbest m

A simple framework for cooperation of evolutionary algorithms in the solution of constrained optimization problems is proposed and implemented using two advanced adaptive variants of differential evolution. The new algorithm is applied to the test pr
