Objective: Telomere length (TL) has been identified as a marker for biological, cardiovascular aging and cardiovascular events risk. Increased arterial stiffness and intima-media thickness (IMT) are the main signs of arterial aging and strong predictors for the development of cardiovascular disease....

Introduction: Left Main Coronary Artery (LMCA) disease is prognostically the most important coronary lesion. LMCA differs from the other coronaries in having high elastin content. Aortic Pulsatility (AP) is an independent predictor of cardiovascular events in CAD. We hypothesized that pulsatile stress...

Objectives: To compare indices of vascular stiffness and markers of adiposity and inflammation in “healthy” subjects with/without components of the metabolic syndrome (met-x). Methods: Subjects satisfying ≥1 (≥1 Met-X;) and no criteria (0 Met-X) were recruited (IDF 2006). All were lifelong non-smokers,...

The modeling and analysis of lifetimes is an important aspect of statistical work in a wide variety of scientific and technological fields. For the first time, the called Kumaraswamy Pareto distribution, is introduced and studied. The new distribution can have a decreasing and upside-down bathtub failure...

Previously, we concluded that a mother's rocking motion is the most effective motion for inducing sleep in adults. We call it the candidate rocking motion. In this study, we confirm that the candidate rocking motion is more effective in inducing sleep than using no rocking motion. Moreover, we find that...

This paper considers the problem of non-fragile finite-time guaranteed cost fuzzy control for continuous-time nonlinear systems. Firstly, the definition on finite-time stability (FTS) for continuous-time nonlinear systems is provided and we give a novel and explicit interpretation for non-fragile finite-time...

We propose a method of quantization of certain Lie bialgebra structures on the polynomial Lie algebras related to quasi-trigonometric solutions of the classical Yang-Baxter equation. The method is based on so-called affinization of certain seaweed algebras and their quantum analogues.

We study the dominant terms of systems of Lotka-Volterra-type which arise in the the mathematical modelling of the evolution of many divers natural systems from the viewpoint of both symmetry and singularity analyses. The connections between an increase in the amount of symmetry possessed by the system...

On the basis of a subgroup structure of the Poincaré group P(1, 3) the ansatzes which reduce the Monge­Ampere equation to differential equations with fewer independent variables have been constructed. The corresponding symmetry reduction has been done. By means of the solutions of the reduced equations...

Sickle cell disease patients are commonly treated at transfusion medicine services, and understanding of the hepatic manifestations of the disease is key for optimal management, specifically, in individuals presenting with sickle cell intrahepatic cholestasis (SCIC). SCIC represents a rare, severe hepatic...

In this work, we use a computational technique with multiple properties of consistency in order to approximate solutions of a bounded β-Fermi–Pasta–Ulam lattice in two space dimensions subject to harmonic driving in two adjacent boundaries. The processes of nonlinear supratransmission and infratransmission...

Building on previous investigations, we show that Gerstner's famous deep water wave and the related edge wave propagating along a sloping beach, found within the context of water of constant density, can both be adapted to provide explicit free surface flows in incompressible fluids with arbitrary...

We show that we can apply the Hirota direct method to some non-integrable equations. For this purpose, we consider the extended Kadomtsev–Petviashvili–Boussinesq (eKPBo) equation with M variable which is (uxxx−6uux)x+a11uxx+2∑k=2Ma1kuxxk+∑i,j=2Maijuxixj=0, where aij = aji are constants and xi = (x,...

We study the elliptic sinh-Gordon equation formulated in the quarter plane by using the so-called Fokas method, which is a significant extension of the inverse scattering transform for the boundary value problems. The method is based on the simultaneous spectral analysis for both parts of the Lax pair...

Image Quality Assessment (IQA) is a vital element in improving the efficiency of an automatic recognition system of various wood species. There is a need to develop a No-Reference IQA (NR-IQA) system as a perfect and distortion free wood images may be impossible to be acquired in the dusty environment...

Objectives: The aim of our study was to investigate the relationship between glucose metabolism, high sensitivity C-reactive protein (hsCRP), advanced glycation end-products (AGEs) and aortic stiffness in non-diabetic middle aged metabolic syndrome (MetS) subjects. Methods: We studied a total of 486...

Objectives: In developing countries, urbanization leads to changes in behavioural lifestyle and malnutrition which may lead to higher rates of cardiovascular disease .1,2 We aimed to assess the association between low body mass index and markers of cardiovascular function like pulse wave velocity in...

Background: Carotid femoral pulse wave velocity (cfPWV) is directly associated with arterial stiffness in major elastic arteries and predicts future cardiovascular events (1).
