Background: Arterial stiffness measures have a known dependency on actual blood pressure, requiring due consideration in risk assessment and treatment monitoring. Given the impact of age on arterial wall structural properties, this pressure-dependency might significantly differ between younger and older...

Purpose: Fabry disease is a deficiency of lysosomal enzyme α-galactosidase A leading to accumulation of glycosphyngolipids in cardiac and vascular tissues. After long-term enzyme replacement treatment, we described a continuous vascular hypertrophy whereas the aortic stiffness was paradoxically decreasing....

The increase of arterial volume during the systole (‘pulse volume’) is essential for buffering the pulsatile ventricular output. Objectives: Deriving some mechanical properties of arteries by assuming pulse volume homeostasis. Methods: A model that includes a generalized nonlinear relationship between...

The article develops the decision rules to win each set of the Chinese chess game using evaluation algorithm and artificial intelligence method, and uses the mobile robot to be instead of the chess, and presents the movement scenarios using the shortest motion paths for mobile robots. Player can play...

This paper completes the structure design of the feed process for the small rectification experimental unit. According to the process requirements, the overall scheme of the detection and control system and the main parameters are designed, and the type of the instrument is selected. The system hardware...

This article presents the threshold-based incremental learning model for a case-base updating approach that can support adaptive detection and incremental learning of Case-based Reasoning (CBR)-based automatic adaptable phishing detection. The CBR-based adaptive phishing detection model detects the phishing...

A system is proposed that performs gait analysis of a pedestrian to improve a walk posture and at the same time to prevent a fall. In the system, a user walks with a chest-mounted camera. His/her walking posture is estimated using a pair of images obtained from the camera. Normally it is difficult to...

Background: Vascular Ehlers-Danlos syndrome (vEDS) is a rare severe genetic disease which results from mutations in the gene encoding type III procollagen (COL3A1), characterized by vascular and/or hollow organic ruptures. No treatment is yet validated. We tested the ability of celiprolol, a beta1-adrenoceptor...

Objectives: Human carotid arteries exhibit viscoelastic behaviour characterised by hysteresis of the pressure-diameter relation and longitudinal wall motion1. Ultrasound techniques have been used to measure vessel wall displacements, as well as pressure and diameter waveforms, from which viscoelastic...

Background: It has been demonstrated that aortic stiffness, as determined by the carotid-femoral pulse wave velocity, is an independent predictor of cardiovascular disease. Whether this measure is of use in cardiovascular risk stratification in clinical practice needs to be determined. We investigated...

Aortic stiffness assessed by carotid-to-femoral pulse wave velocity (PWV) often fails to predict cardiovascular (CV) risk and mortality in the very elderly. This may be due to the non-linear association between PWV and compliance, or to blood pressure decrease in the frailest subjects. Moreover, total...

Background: Pulse wave velocity (PWV), measure of aortic stiffness, is predictive of cardiovascular events. PWV is strongly related to age and blood pressure but its relation to other risk factors and presence of calcification is unclear. We sought to determine the association between PWV and cardiovascular...

In case of vascular weakness or thrombosis stents are implanted and brace vessels from the inside to assure the proper blood flow. A widespread method to monitor the state of blood vessels in terms of their stiffness and diameter is to measure the pulse wave velocity (PWV). The stiffer or the narrower...

In this paper, we extend our investigations of a special class of perturbations of copulas introduced in [7]. Despite a surprising fact that this kind of perturbations does not change the value of tail dependence of the original copulas, their use yielded models with considerably improved fitting qualities.

We have proposed a new method of advancing from CS Unplugged through the new process of CS Plugged to full-fledged computer programming languages, as a means of deepening understanding in computer programming education. We also have proposed a new Five-Step Method consisting of the following steps: Step...

Based on the equivalence relation, we can partition a set U, formally, different equivalence relations correspond to different partitions of U. In this paper, based on Yager's work, we discuss how to compare the different partitions, moreover, we obtain some indexes to select a better partition from...

We derive discrete systems which result from a second, not studied up to now, form of the q-PVI equation. The derivation is based on two different procedures: “limits” and “degeneracies”. We obtain several new discrete Painlevé equations along with some linearisable systems. The parallel between the...

Some diseases, such as renal colic, stroke, and myocardial infarction, correlate with seasonality and microclimatic variations. Although evidence is limited and controversial, a correlation between acute-onset atrial fibrillation (AAF) and seasonality has been previously reported. In order to elucidate...

Introduction: Morphological variations in primary dentition are of great concern to a pediatric dentist as it may pose clinical problems like dental caries, delayed exfoliation and also anomalies in the permanent dentition, such as impaction of successors, supernumerary teeth, permanent double teeth...

Background: To investigate physical fitness as a mediator of the relationship between arterial stiffness and cognitive function in seniors. Methods: This is a cross-sectional study comprising 155 individuals free from chronic diseases (75.5 ± 6.5 years; 69.7% female). Carotid-femoral pulse wave was...

Cancer is the second most frequent cause of death worldwide after ischemic heart disease. Early detection of cancer is a cornerstone of cancer survival. The aim of this review is to summarize the current knowledge, awareness, attitude, and practice of cancer screening programs in Saudi Arabia. A literature...

Using detailed analysis of the stage structure of the kabuki-dance Kyōganoko Musume Dōjōji, as well as the legend of Dōjōji that comprises the background of the kabuki-dance, we present a 2D simulation system that uses music, lyrics, and images. A prototype system was then developed that complements...

This paper studies structures of the 3-Lie algebra M realized by the general linear Lie algebra gl(n, ℂ). We show that M has only one nonzero proper ideal. We then give explicit expressions of both derivations and inner derivations of M. Finally, we investigate substructures of the (inner) derivation...

The flow of a superfluid film adsorbed on a porous medium can be modeled by a meromorphic differential on a Riemann surface of high genus. In this paper, we define the mixed Hodge metric of meromorphic differentials on a Riemann surface and justify using this metric to approximate the kinetic energy...
