and Applied Analysis 3 In scientific and engineering computations, many eigenvalue problems have the following first type of mixed variational formulation: find λ, u, σ ∈ R × V × W , u, σ / 0, 0 , such that a ( u, ψ ) b ( ψ, σ ) λ ( u, ψ ) D, ∀ψ ∈ V, 2.3 b u, v 0, ∀v ∈ W. 2.4 In order to solve problem 2.3 2.4 , one should construct finite element spaces Vh ⊂ V and Wh ⊂ W . Restricting 2.3 2.4 o...
Using a contraction procedure, we construct a twist operator that satisfies a shifted cocycle condition, and leads to the Jordanian quasi-Hopf Uh;y(sl(2)) algebra. The corresponding universal Rh(y) matrix obeys a Gervais-Neveu-Felder equation associated with the Uh;y(sl(2)) algebra. For a class of representations, the dynamical Yang-Baxter equation may be expressed as a compatibility condition ...
Let M be a manifold with an action of a Lie group G, A the function algebra on M . The first problem we consider is to construct a Uh(g) invariant quantization, Ah, of A, where Uh(g) is a quantum group corresponding to G. Let s be a G invariant Poisson bracket on M . The second problem we consider is to construct a Uh(g) invariant two parameter (double) quantization, At,h, of A such that At,0 i...
OBJECTIVE To compare the image quality and dose of radiation in two groups of patients undergoing CT angiography of the lower limbs, one with tube voltage of 80 kV and the other with tube voltage of 100 kV. MATERIAL AND METHODS We performed CT angiography of the lower limbs in 60 patients with suspected peripheral arterial disease. Patients were randomly assigned to one of two groups; in one ...
INTRODUCTION Neonatal mortality associated with preterm birth can be reduced with antenatal corticosteroids (ACS), yet <10% of eligible pregnant women in low-middle income countries. The inability to accurately determine gestational age (GA) leads to under-identification of high-risk women who could receive ACS or other interventions. To facilitate better identification in low-resource settings...
BACKGROUND Aiming at improving the use of echocardiography tests, the Appropriateness Criteria (AC) were created by the American Society of Echocardiography (ASE)/American College of Cardiology (ACC). OBJECTIVE To compare the appropriateness profile of transthoracic echocardiography (TTE) requests in accordance with the AC, between a public University Hospital (UH) and a Private Hospital (PH)...
