Integration of acoustic radiation force and optical imaging for blood plasma clot stiffness measurement. [PDF]
PLoS ONE, 2015 Despite the life-preserving function blood clotting serves in the body, inadequate or excessive blood clot stiffness has been associated with life-threatening diseases such as stroke, hemorrhage, and heart attack.

The spectral measure and Hilbert transform of a measure-preserving transformation [PDF]
Transactions of the American Mathematical Society, 1989 V. F. Gaposhkin gave a condition on the spectral measure of a normal contraction on L 2 {L^2} sufficient to imply that the operator satisfies the pointwise ergodic theorem. We prove that unitary operators which come from measure-preserving transformations satisfy a stronger version of this condition.

Logical entropy of dynamical systems
Advances in Difference Equations, 2018 The main purpose of the paper is to extend the results of Ellerman (Int. J. Semant. Comput. 7:121–145, 2013) to the case of dynamical systems. We define the logical entropy and conditional logical entropy of finite measurable partitions and derive the ...

Image completion via transformation and structural constraints
EURASIP Journal on Image and Video Processing, 2020 Image completion is an approach to fill a damaged region (hole) in an image. In this study, we adopt a novel method which can repair a target region with structural constraints in an architectural scene. An objective function that consists of three terms

Almost everywhere convergence of convolution powers without finite second moment [PDF]
, 2010 We generalize a theorem of Bellow and Calder\'on concerning the a.e. convergence of the convolution powers $\ds \mu^nf(x)=\sum_{k}\mu^n(k)f(T^k x)$ where $T$ is a measure preserving transformation of a probability space and $\mu$ is a probability measure

Sublinear functionals ergodicity and finite invariant measures
International Journal of Mathematics and Mathematical Sciences, 1989 By introducing a sublinear functional involving infinite matrices, we establish its connection with ergodicity and measure preserving transformation. Further, we characterize the existence of a finite invariant measure by means of a condition involving ...

A mixing dynamical system on the cantor set
International Journal of Mathematics and Mathematical Sciences, 1995 In this paper we give mixing properties (ergodic, weak-mixng and strong-mixing) to a dynamical system on the Cantor set by showing that the one-sided (12,12)-shift map is isomorphic to a measure preserving transformation defined on the Cantor ...

IEEE Access, 2013 The signal processing concept of signal-to-noise ratio (SNR), in its role as a performance measure, is recast within the more general context of information theory, leading to a series of useful insights. Establishing generalized SNR (GSNR) as a rigorous
