mutualistic interaction between aphids and ants is one of the classical examples of mutualism. the current study was carried out during 2013-2014 in golestan province, north-eastern iran, to investigate the myrmecophilous aphids and their relationships with ants. in this study, 11 ant species representing seven genera and two subfamilies associated with 12 aphid species belonging to two subfami...

T oday science is in the age of biology and biology is in the age of genomics. Sequencing the entire genome of an organism, an enterprise that could not have been imagined barely 50 y ago, is being thought of as the first step toward a complete understanding of its biology. If I had been asked to recommend just two families of living organisms from which to pick the first two species for whole-...

Background Cognitive impairment due to multiple sclerosis (MS) is common and often limits occupational functioning, contributes disability, reduces quality of life. Early detection cognitive involvement in MS critical for treatment planning intervention, frequent, regular monitoring may provide insight into subtle changes disease progression. Objective To compare the sensitivity specificity cli...

In the preceding paper are described the lesions which follow the inoculation of certain non-hemolyt ic streptococci into the skin of the rabbit ; such lesions begin to decrease in size af ter 24 to 48 hours bu t in over 50 per cent of animals show a recrudescence of act iv i ty about the 8 th or 9th day. This phenomenon we have te rmed the secondary reaction. I t usually fails to occur in anim...

This paper sets up an Artificial Bee Colony (ABC) algorithm for evolving ant direction Ant Colony Optimization (ACO) to solve the Economic Power Dispatch (EPD) problem. The method ABC-ACO employs the bee colony to find a suitable and the best values operators to improve the ACO. The feasibility of the proposed approach was tested on IEEE 57-bus system. The proposed approach simulation results, ...

Anger is a negative and highly aroused emotion. Previous research has revealed that a high level of arousal can induce the participant in a physical preparation and self-awareness. The aim of this research was to study the influence of anger on the attentional network using the Attention Network Test-Interactions (ANT-I). This test has been developed in order to assess 3 attentional networks: a...

Ant miner is a data mining algorithm based on Ant Colony Optimization (ACO). Ant miner algorithms are mainly for discovery rule for optimization. Ant miner + algorithm uses MAX-MIN ant system for discover rules in the database. Soil classification deals with the systematic categorization of soils based on distinguished characteristics as well as criteria. The proposed model delivers to Ant mine...
