In many applications such as credit risk management, data are represented as high-dimensional feature vectors. It makes the feature selection necessary to reduce the computational complexity, improve the generalization ability and the interpretability. In this paper, we present a novel feature...

Dodecylamine spontaneously adsorbs on carbon steel via its polar group (-NH2) in hydrochloric acid solution. Furthermore, it forms a monolayer film on carbon steel surface. The inhibition mechanism of dodecylamine for carbon steel is geometric blocking effect. The adsorption of dodecylamine on...

The Artificial Bee Colony (ABC) algorithm is one of the most recent swarm intelligence based algorithms which simulates the foraging behavior of honey bee colonies. In this work, a particle swarm inspired multi-elitist ABC algorithm named PS-MEABC is proposed and applied for real-parameter...

Objective The purpose of this study was to examine inequalities of access to health care among the urban elderly in northwestern China.Methods 4441 seniors (over 60 years of age) were drawn from a cross-sectional study conducted in three northwestern Chinese cities. The effects of these factors...

Electricity generation from thermal irradiation governed by GaSb diode has been systematically investigated in its normal and inverted configuration. It is demonstrated here that there is a critical base doping, 3 × 1017 cm−3, for the normal structure, and the superior output performance...

This paper proposes a procurement mechanism for a research and development (R&D) project, in which the stochastic nature of R&D is incorporated, and the potential agents needed to invest prior to the agent are selected. The incentive contract aims to attract the investment of potential agents...

Central Asia including Kyrgyzstan is a disaster prone area, suffering from snow avalanches, landslides and flooding. Within the Tyan-Shan region, a mountainous region in Southern Kyrgyzstan, there is an increasing number of natural hazards over the last years. One of the possible causes of the...
