We study a two-component dark matter model consisting of Dirac fermion and complex scalar charged under new U(1) gauge group in the hidden sector. The plays dominant component which explains measured DM relic density Universe. It has no direct coupling to ordinary standard particles, thus evading strong constraints from detection experiments. is self-interacting through light boson it would be ...

p2x 7 antagonist activity for a set of 49 molecules of the p2x 7 receptor antagonists, derivatives of purine, was modeled with the aid of chemometric and artificial intelligence techniques. the activity of these compounds was estimated by means of combination of principal component analysis (pca), as a well-known data reduction method, genetic algorithm (ga), as a variable selection technique, ...

Background: Study in design to incorporate accelerated proliferation correction factors into linearquadratic and multiple-component models. Materials and Methods: Accelerated proliferation rate correction factor has been incorporated into the linearquadratic and the multiple component models by applying accelerated exponential cell growth to explain the tumor cell kinetics and estimates proper ...

among various reported membrane-based gas separation processes, the best explanation is generally achieved by the solution-diffusion model. the main factors in this model are the solubility and diffusivity of permeationcomponents through the membrane. the prediction of permeability and diffusivity in multicomponent gas permeation as well as the separation evaluation equilibrium and kinetic inte...

in this research by applying the theoretical framework of socio-technical systems and literature review using the form of e-government has been identified as a core component. to realize the model results and the results indicated that each of the six components of e-government in 1404 particularly in the areas of communication and access to digital content. based on the results of the highest ...
