The quasi-linear approximation for electromagnetic forward modeling is based on the assumption that the anomalous electrical field within an inhomogeneous do­ main is linearly proportional to the background (nor ­ mal) field through an electrical reflectivity tensor t In the original formulation of the quasi-linear approxima­ tion, 1 was determined by solving a minimization prob ­ lem based on ...

We consider quasi-variational inequalities (QVIs) with general non-local drivers and related systems of reflected backward stochastic differential equations (BSDEs) in a Brownian filtration. show existence uniqueness viscosity solutions to the QVIs by first considering standard (local) setting then applying contraction argument. In addition, argument yields BSDEs extends theory probabilistic re...

In this article, we study the existence of tripled coincidence and tripled common fixed point theorems in partially ordered complete quasi-metric spaces for nonlinear contraction condition related to Q-function q. Our results generalize and modify several comparable results in the literature. We also provide illustrative examples in support of our new results. Mathematics Subject Classification...

Abstract Introduction: Pregnancy predisposes the emergence of pelvic floor dysfunctions (PFD), postpartum being opportune moment to assess these muscles. Objective: To investigate effect instructions and verbal feedback on contraction capacity muscles (PFM) in women. Methods: Quasi-experimental study with 109 women immediate vaginal at a reference maternity hospital Fortaleza, Ceará state, Braz...

1. Presenting lower and upper bounds on the complexity of testing Bipartitness; specifically, we present a poly(1/ǫ) · Õ( √ k)-time tester, and an Ω √ k) lower bound on the query complexity of any tester for Bipartitness. 2. Reviewing a quasi-poly(1/ǫ)-time tester for Planarity. The result extends to testing any minor-closed property (i.e., a graph property that is preserved under the omission ...

Allowing for creatine kinase buffering of changes in adenine nucleotide concentrations, and the known relationship between muscle performance and rate of ATP hydrolysis by myosin, the variation of exerted force with intracellular Gibbs energy of ATP hydrolysis is calculated for voluntary muscle contraction. The resulting relationship is sigmoidal, most of the operating range coinciding with the...

This paper considers the existence, uniqueness and non-existence of solution for a quasi-linear fractional boundary value problems with sign-changing Green’s function. Under certain growth conditions on the nonlinear term, we employ the Leray-Schauder alternative fixed point theorem to obtain an existence result of nontrivial solution and use the Banach contraction mapping principle to obtain a...
