Ant colony optimisation-based radiation pattern manipulation algorithm for electronically steerable array radiator antennas [PDF]
A new algorithm for manipulating the radiation pattern of Electronically Steerable Array Radiator Antennas is proposed. A continuous implementation of the Ant Colony Optimisation (ACO) technique calculates the optimal impedance values of reactances ...

Ant trail pheromone biosynthesis is triggered by a neuropeptide hormone.
Our understanding of insect chemical communication including pheromone identification, synthesis, and their role in behavior has advanced tremendously over the last half-century.

Alarm Pheromone in a Gregarious Poduromorph Collembolan (Collembola: Hypogastruridae) [PDF]
We report an alarm pheromone in the gregarious poduromorph collembolan, Hypogastrura pannosa. Cuticular rupture results in emission of a rapidly vaporizing hexane-soluble material with an active space diameter of ca. 1 cm.

Functional Characterization of Sex Pheromone Receptors in the Fall Armyworm (Spodoptera frugiperda)
Pheromone receptors (PRs) found in the antennae of male moths play a vital role in the recognition of sex pheromones released by females. The fall armyworm (FAW), Spodoptera frugiperda, is a notorious invasive pest, but its PRs have not been reported. In

Pheromone Guidance of Polarity Site Movement in Yeast
Cells’ ability to track chemical gradients is integral to many biological phenomena, including fertilization, development, accessing nutrients, and combating infection. Mating of the yeast Saccharomyces cerevisiae provides a tractable model to understand

Mammalian pheromones control a myriad of innate social behaviors and acutely regulate hormone levels. Responses to pheromones are highly robust, reproducible, and stereotyped and likely involve developmentally predetermined neural circuits. Here, I review several facets of pheromone transduction in mammals, including (a) chemosensory receptors and ...

Memory-based immigrants for ant colony optimization in changing environments [PDF]
Copyright @ 2011 SpringerAnt colony optimization (ACO) algorithms have proved that they can adapt to dynamic optimization problems (DOPs) when they are enhanced to maintain diversity.

Double-attraction method to control Frankliniella occidentalis (Pergande) in pepper crops in Tunisia
Blue sticky traps with and without pheromone capsules were used to monitor and control Frankliniella occidentalis Pergande (1895) (Thysanoptera; Thripidae) in pepper crop greenhouses in Tunisia.

An ant colony genetic fusion routing algorithm based on soft define network
Abstract Aiming at the problem that there are many paths in data forwarding in soft define network (SDN) network, and the optimal path is difficult to find, combined with the advantages of ant colony algorithm and Genetic algorithm (GA), a routing control strategy based on the ant colony genetic fusion algorithm is proposed.
