Effect of Host Human Products on Natural Transformation in Acinetobacter baumannii
(Springer, 2019-08)
Our previous data show that serum albumin can trigger natural transformation in Acinetobacter baumannii. However, extracellular matrix/basal membrane components, norepinephrine, and mucin did not have a significant effect ...
Iterated Aluthge transforms: a brief survey
(Unión Matemática Argentina, 2008-12)
Abstract. Given an r × r complex matrix T, if T = U|T| is the polar decomposition of T, then, the Aluthge transform is defined by ∆ (T) = |T| 1/2U|T| 1/2 . Let ∆n(T) denote the n-times iterated Aluthge transform of T, i.e. ...
Weighted inequalities for commutators of Schrödinger-Riesz transforms
(Academic Press Inc Elsevier Science, 2012-08)
In this work we obtain weighted and weak estimates for the commutator of the Riesz transforms associated to a Schrödinger operator , where V satisfies some reverse-Hölder inequality. The classes of weights as well as the ...
A cellular automaton-finite difference simulation of the ausferritic transformation in ductile iron
(Maney Publishing, 2018-09-22)
The development of the ausferritic transformation of a ductile iron was analysed using a novel cellular automaton-finite difference model, which considers geometrical details of the microstructure, nucleation of the new ...
Convergence of the iterated Aluthge transform sequence for diagonalizable matrices
(Academic Press Inc Elsevier Science, 2007-12-01)
Given an r × r complex matrix T, if T = U | T | is the polar decomposition of T, then, the Aluthge transform is defined byΔ (T) = | T |1 / 2 U | T |1 / 2 . Let Δn (T) denote the n-times iterated Aluthge transform of T, ...
Spectral estimation of terahertz time-domain signals using a simple parametric method
(Institution of Engineering and Technology, 2015-12)
A simple method for spectral estimation of terahertz signals using an autoregressive model is developed. The technique shows a better spectral variance and resolution over the use of the Fast Fourier Transform, which is ...
The iterated Aluthge transforms of a matrix converge
(Academic Press Inc Elsevier Science, 2011-01)
Given an r×r complex matrix T, if T=U|T| is the polar decomposition of T, then, the Aluthge transform is defined by. Δ(T)=|T|1/2U|T|1/2. Let Δn(T) denote the n-times iterated Aluthge transform of T, i.e., Δ0(T)=T and ...
Power transformers monitoring based on electrical measurements: State of the art
(Institution of Engineering and Technology, 2018-07-10)
Faults diagnosis in power transformers has been traditionally based on the insulation resistance measurement, polarisation index, analysis of dissolved gasses in oil, dissipation/power factor measurement, and partial ...
Relationship between transformational leadership and hope. Study of 100 Chilean business leaders
(Universidad Nacional de Misiones. Facultad de Ciencias Económicas. Programa de Posgrado en Administración, 2015-06-19)
The relationship between hope and transformational leadership has been little explored and the few existing studies on this topic have been conducted in the United States. The present study shows the relationship between ...
Martensitic transformation in as-grown and annealed near-stoichiometric epitaxial Ni2MnGa thin films
(Taylor & Francis Ltd, 2015-07-24)
Magnetic shape memory nanostructures have a great potential in the field of the nanoactuators. The relationship between dimensionality, microstructure and magnetism characterizes the materials performance. Here, we study ...
