Reliability of the optimized perturbation theory in the 0-dimensional O(N) scalar field model
(Elsevier B.V., 2016-12-15)
We address the reliability of the Optimized Perturbation Theory (OPT) in the context of the 0-dimensional O(N) scalar field model. The effective potential, the self-energy and the 1PI four-point Green's function for the ...
On the regularization of mixed complementarity problems
(2000-12-01)
A variational inequality problem (VIP) satisfying a constraint qualification can be reduced to a mixed complementarity problem (MCP). Monotonicity of the VIP implies that the MCP is also monotone. Introducing regularizing ...
Multiplicative Lidskii's inequalities and optimal perturbations of frames
(Elsevier Science Inc, 2015-03-15)
In this paper we study two design problems in frame theory: on the one hand, given a fixed finite frame F={fj}j∈In for Cd we compute those dual frames G of F that are optimal perturbations of the canonical dual frame for ...
QSPR-Perturbation Models for the Prediction of B-Epitopes from Immune Epitope Database: A Potentially Valuable Route for Predicting “In Silico” New Optimal Peptide Sequences and/or Boundary Conditions for Vaccine Development
(Springer, 2016-12)
In the present study, three different physicochemical molecular properties for peptides were calculated using the program MARCH-INSIDE: atomic polarizability, partition coefficient, and polarity. These measures were used ...
An analytical solution for the critical number of particles for stable bose-einstein condensation under the influence of an anisotropic potential
(Sociedade Brasileira de Física, 2008)
We have considered a Bose gas in an anisotropic potential. Applying the the Gross-Pitaevskii Equation (GPE) for a confined dilute atomic gas, we have used the methods of optimized perturbation theory and self-similar root ...
