Background: Fibrillin-1 is an important constituent of the vascular wall and earlier studies have indicated an effect of the fibrillin-1 2–3 genotype on blood pressure as well as aortic stiffness. The aim was to determine if the Fibrillin-1 2–3 genotype is associated with increased cardiovascular morbidity/mortality...

The middle-size league soccer competition is an important RoboCup event designed to promote advancements in Artificial Intelligence (AI) and robotics. In recent years, soccer robots using a dribbling mechanism, through which the ball is controlled using two driving rollers, have been adopted by teams...

Background: Supine hypertension, a consequence of autonomic neuropathy, is a rarely recognized pathological condition. Reported diseases in the background are pure autonomic failure, multiple system atrophy, Parkinson’s disease, diabetes and different autoimmune disorders. Methods: In our case report...

It is well known that the celebrated Lorenz system has an attractor such that every orbit ends inside a certain ellipsoid in forward time. We complement this result by a new phenomenon and by a new interpretation. We show that “infinity” is a global repeller for a set of parameters wider than that usually...

We present an explicit representation of an N-fold Darboux transformation T̃N for the short pulse equation, by the determinants of the eigenfunctions of its Lax pair. In the course of the derivation of T̃N, we show that the quasi-determinant is avoidable, and it is contrast to a recent paper (J. Phys....

Background: The clinical importance of central blood pressure (BP) and heart rate corrected augmentation index (AIxHR75) has been gradually increasing in recent years. Objectives: We measured the peripheral and central BP, the AIxHR75 of healthy volunteers with special regard to diurnal variation (8...

Introduction: Hypertension and renal dysfunction are associated with increased arterial stiffness. Arterial stiffness is a marker of cardiovascular disease and predictor of cardiovascular risk. We assessed the relationship between renal function and arterial stiffness in never-treated hypertensives. Methods:...

Recent follow-up studies showed no change or even short-term improvement of arterial stiffness after kidney transplantation. Data from general population and end-stage renal disease patients suggest, that PWV increases with age of 0,07–0,08m/s for each year of life. It was shown recently that reduced...

We have already proposed an obstacles detection method using a video taken by a vehicle-mounted monocular camera. In this method, correct obstacles detection depends on whether we can accurately detect and match feature points. In order to improve the accuracy of obstacles detection, in this paper, we...

Nowadays, effective management of water withdraw, water consumption and wastewater discharge is desired for nuclear power plants in inland China. In this paper, the inland nuclear power industry and its policies in China were reviewed, a two-step water-management (TSWM) approach for the plants was proposed....

The Marshall-Olkin extended uniform distribution is introduced and studied by Jose and Krishna (2011). In this paper some moments properties of generalized order statistics (gos) for this distribution are investigated and results are deduced for order statistics and record values. In the last section,...

We discuss a method of solving nth order scalar ordinary differential equations by extending the ideas based on the Prelle-Singer (PS) procedure for second order ordnary differential equations. We also introduce a novel way of generating additional integrals of motion from a single integral. We illustrate...

Reductions for systems of ODEs integrable via the standard factorization method (the Adler-Kostant-Symes scheme) or the generalized factorization method, developed by the authors earlier, are considered. Relationships between such reductions, operator Yang-Baxter equations, and some kinds of non-associative...

Underwater sensor deployment for military surveillance is a significant challenge due to the inherent difficulties posed by the underwater channel in terms of sensing and communications between sensors, as well as the exorbitant cost of the sensors. As a result, these sensors must be deployed as efficiently...

In the knowledge economy, a key source of sustainable competitive advantage relies on the way to create, share, and utilize knowledge. Knowledge Management (KM) tools assumed an important role in supporting KM activities. The objective of this paper is to aid decision makers to identify the most appropriate...

In analyzing most correlated outcomes, the popular multivariate Gaussian distribution is very restrictive and therefore dependence modeling using copulas is nowadays very common to take into account the association among mixed outcomes. In this paper, we use Gaussian copula to construct a joint distribution...

In this paper we formulate a stand alone method to derive maximal number of linearizing transformations for nonlinear ordinary differential equations (ODEs) of any order including coupled ones from a knowledge of fewer number of integrals of motion. The proposed algorithm is simple, straightforward and...

The note provides the relation between symmetries and first integrals of Itô stochastic differential equations and symmetries of the associated Kolmogorov Backward Equation (KBE). Relation between the symmetries of the KBE and the symmetries of the Kolmogorov forward equation is also given.

Purpose: It is well known that regular moderate aerobic exercise has a beneficial effect on cardiovascular risk, although the impact of long-term intense aerobic training has not been defined. Aortic stiffness and wave reflections are independent predictors of cardiovascular risk. In this study we assessed...

Background In primary care, much effort goes into risk factor management. Early recognition of vascular dysfunction in patients should inform intervention to reduce vascular risk. Very few studies have looked at the application of augmentation index (AI) measurement in primary care, particularly in...

Objective: To determine whether the structural status of carotid arteries and abnormal flow-mediated dilatation (FMD) in the brachial artery identify young and middle-aged men with coronary artery disease (CAD). Methods: A total of 78 men aged 28 to 50 (mean 43±5) years underwent carotid ultrasound...

This study proposes a method of body dynamics analysis for larval zebrafish incorporating a viscoelastic body model and a fluidic environment model to support the study of development mechanisms in motion generation. The results showed that the estimated fluid drag coefficients enabled the body dynamics...

An N = (2|2) superfield formulation of the N = (1|1) supersymmetric Toda lattice hierarchy is proposed, and its five real forms are presented.

Renormalization group flow equations for scalar 4 are generated using smooth smearing functions. Numerical results for the critical exponent in d = 3 are caculated by polynomial truncation of the blocked potential. It is shown that the covergence of with the order of truncation can be improved by fine...

In September 2014, an outbreak of gastroenteritis was reported to the Public Health Institute of Šibenik and Knin County in Croatia. The outbreak occurred in the County center of Šibenik, a town with 50,000 inhabitants, and it lasted for 12 days. An epidemiological investigation suggested a nearby water...
