Abstract This paper proposes a new stochastic optimizer called the Colony Predation Algorithm (CPA) based on corporate predation of animals in nature. CPA utilizes mathematical mapping following strategies used by animal hunting groups, such as dispersing prey, encircling supporting most likely successful hunter, and seeking another target. Moreover, proposed introduces features unique model th...

Normal mouse serum (NMS) devoid of colony-stimulating factor (CSF) was found to enhance the interleukin 3 (IL-3)-driven colony formation of bone marrow in vitro. Inclusion of NMS in bone marrow colony-forming assays resulted in greatly increased numbers of colonies and clusters following seven days incubation; however, incubation of bone marrow with NMS before the colony-forming assay had no ef...

Staphylococcus aureus colonies can spread on soft agar plates. We compared colony spreading of clinically isolated methicillin-sensitive S. aureus (MSSA) and methicillin-resistant S. aureus (MRSA). All MSSA strains showed colony spreading, but most MRSA strains (73%) carrying SCCmec type-II showed little colony spreading. Deletion of the entire SCCmec type-II region from these MRSA strains rest...

In this study I examined how the paper wasp, Polistes fuscatus, defends a colony when faced with a vertebrate attack. I looked for a division of labour in defensive behaviour within a colony and examined whether this behaviour changes over the colony cycle. The colonies were presented with a model of an adult red-winged blackbird, Agelaius phoeniceus, and a speaker that vibrated the comb. There...

the one-dimensional cutting stock problem, has so many applications in lots of industrial processes and during the past few years has attracted so many researchers’ attention all over the world. in this paper a meta-heuristic method based on aco is presented to solve this problem. in this algorithm, based on designed probabilistic laws, artificial ants do select various cuts and then select the...
