One of the most powerful tools for solving optimization problems is algorithms (inspired by nature) based on populations. These provide a solution to problem randomly searching in search space. The design’s central idea derived from various natural phenomena, behavior and living conditions organisms, laws physics, etc. A new population-based algorithm called Binary Spring Search Algorithm (BSSA...

The neural systems that control escape behavior have been studied intensively in several animals, including mollusks, fish and crayfish. Surprisingly little is known, however, about the activation and the utilization of escape circuits during prey-predator interactions. To complement the physiological and anatomical studies with a necessary behavioral equivalent, we investigated encounters betw...

Dragonflies are good indicators of environmental health and biodiversity. Most studies addressing dragonfly ecology have focused on the importance of aquatic habitats, while the value of surrounding terrestrial habitats has often been overlooked. However, species associated with temporary aquatic habitats must persist in terrestrial environments for long periods. Little is known about the impor...

Spectral sensitivities were recorded intracellulary in median ocelli of Anax junius, Aeschnatuberculifera, and Libellulapulcella. All cells had peak sensitivities at 360 and 500 nm while UV-blue+green cells found only in Anax had a third peak sensitivity at 440 nm. Ratios of UV-to-green sensitivities varied from cell to cell in each ocellus, but no UV-only or green-only cells were recorded. Hal...

Many animals have two basic traits for avoiding being killed by a predator: behavioral modification and morphological defense. We examined the relationship between antipredator behavior and morphological defense in larvae of three closely related dragonfly species within the genus Leucorrhinia. The three species differ with regard to their morphological defense as expressed in the length of the...

In this work, a recent heuristic method called Dragonfly Algorithm (DA) has been employed for the first time to investigate temperature effect on Schottky diode electrical parameters. Beryllium-doped Al0.29Ga0.71As diodes grown by molecular beam epitaxy (MBE) have used validate suggested method. The proposed approach is based analysis of current-voltage-temperature (I–V-T) and capacitance-volta...

Dragonfly cyclovirus (DfCyV), a new species of ssDNA virus discovered using viral metagenomics in dragonflies (family Libellulidae) from the Kingdom of Tonga. Metagenomic sequences of DfCyV were similar to viruses of the recently proposed genus Cyclovirus within the family Circoviridae. Specific PCRs resulted in the recovery of 21 DfCyV genomes from three dragonfly species (Pantala flavescens, ...

The dragonfly topology is becoming a popular choice for building high-radix, low-diameter networks with high-bandwidth links. Even with a powerful network, preliminary experiments on Edison at NERSC have shown that for communication heavy applications, job interference and thus presumably job placement remains an important factor. In this paper, we explore the effects of job placement, job size...
