Texture analysis of aggressive and nonaggressive lung tumor CE CT images [PDF]
, 2008 This paper presents the potential for fractal analysis of time sequence contrast-enhanced (CE) computed tomography (CT) images to differentiate between aggressive and nonaggressive malignant lung tumors (i.e., high and low metabolic tumors).

Energy Dissipation in Fractal-Forced Flow [PDF]
, 2006 The rate of energy dissipation in solutions of the body-forced 3-d incompressible Navier-Stokes equations is rigorously estimated with a focus on its dependence on the nature of the driving force.

Towards a More General Type of Univariate Constrained Interpolation With Fractal Splines
, 2015 Recently, in [Electronic Transaction on Numerical Analysis, 41 (2014), pp. 420-442] authors introduced a new class of rational cubic fractal interpolation functions with linear denominators via fractal perturbation of traditional nonrecursive rational ...

A Wiener-Laguerre model of VIV forces given recent cylinder velocities [PDF]
, 2010 Slender structures immersed in a cross flow can experience vibrations induced by vortex shedding (VIV), which cause fatigue damage and other problems. VIV models in engineering use today tend to operate in the frequency domain.

The Smoothness of Fractal Interpolation Functions on ℝ and on p-Series Local Fields
Discrete Dynamics in Nature and Society, 2014 A fractal interpolation function on a p-series local field Kp is defined, and its p-type smoothness is shown by virtue of the equivalent relationship between the Hölder type space CσKp and the Lipschitz class Lipσ,Kp. The orders of the p-type derivatives

Myocardial Perfusion Defects in Hypertrophic Cardiomyopathy Mutation Carriers
Journal of the American Heart Association, EarlyView., 2021 Background Impaired myocardial blood flow (MBF) in the absence of epicardial coronary disease is a feature of hypertrophic cardiomyopathy (HCM). Although most evident in hypertrophied or scarred segments, reduced MBF can occur in apparently normal segments.
