Objective: The aim of this study was to evaluate the acute effects of participation in Ironman triathlon competition on carotid properties, in relation to hemodynamic load. Methods: 28 male triathletes (41±8 years), participating at the Ironman competition (swimming 3.8 km, cycling 180 km, running 42,2...

China is one of the most severely affected countries by coastal erosion. About 70% of the sandy beaches and most of muddy tidal flat in open water regions are erode. Coastal erosion results in the width of beach being narrowed, bathing beach destruction, coast-protection facilities and roads collapse,...

The multiple model adaptive control (MMAC) of discrete-time stochastic system with colored noise is considered in this paper. Model set contains one adaptive identification and some fixed models. Based on the output errors of the models, a simple weighting algorithm is adopted with guaranteed convergence....

The network platform connecting multiple agents, which is embedded in the models to integrate individual wisdoms into a great wisdom, is called Internet of intelligences (IOI). The risk radar can be driven by IOI with mathematical models written by PHP language. A measure space of the seismic macro-anomalies...

An algorithm for an asymptotic model of wave propagation in shallow-water is proposed and analyzed. The algorithm is based on the Hamiltonian structure of the equation, and corresponds to a completely integrable particle lattice. Each "particle" in this method travels along a characteristic curve of...

Exact solutions of the multidimensional Liouville equation are constructed.

Normal distribution formula is very important to analyze the reciprocity between the random event probability and the events. There exists certain kind of reciprocity between random variable that conforms to normal distribution and its parameter. Solutions to apply normal distribution to the evaluation...

It is shown that the nonlinear pendulum equation can be transformed into a linear harmonic oscillator in the phase space thanks to Kerner’s method [12]. Moreover, as a mathematical divertissement, the second-order differential equation determining the phase-space trajectories of the nonlinear pendulum...

Today one of the key disadvantages of robotic surgery is a lack of a haptic feedback, while in traditional surgery a surgeon uses human haptic senses in all tasks. Providing robots with a haptic feedback have a high potential of reducing time that is spent by a surgeon on suturing subtasks and helping...

Soil-transmitted helminths are among the neglected tropical diseases, although some 1.5 billion individuals are affected. Traveling to endemic regions, global immigration, and increase of immunocompromised cases, in addition to other factors, have an influence on global susceptibility to these parasites....

Congenital cutaneous candidiasis is a rare disease that is usually misdiagnosed as a type of benign neonatal eruption. We report on a preterm infant born with diffuse skin rashes that evolved into various forms and misleading the diagnosis. The persistence of respiratory distress and worsening of chest...

With the aid of the spectral gradient method of Fuchssteiner, the compatible pair of Hamiltonian operators for the coupled NLS hierarchy is rediscovered. This result enables us to construct a hierarchy, which contains a vector generalization of Fokas-Lenells system. The vector Fokas-Lenells system is...

Objective: Carotid-femoral PWV (cfPWV) is a regional marker of vascular ageing: our aim was to take advantage of Magnetic Resonance (MRI) and High resolution Echotracking (HRE) in order to non-invasively investigate the effect of age and blood pressure (BP) on different segments of large arteries. Methods:...

Pregnancy is associated with profound vascular adaptive changes. Cross-sectional studies show greater arterial stiffness in gestational diabetes than in normal pregnancy. However, the time course of maternal cardiovascular hemodynamics in normal and diabetic pregnancy can only be appreciated in longitudinal...

Objectives: Patients with type 2 diabetes (T2DM) are susceptible to exercise-induced albuminuria even at submaximal exercise, but the mechanisms are unknown. Recent data indicates that T2DM patients have raised central blood pressure (BP) during submaximal exercise and this could contribute to renal...

Objective: Studies on changes in arterial stiffness and wave reflections during pregnancy are limited to cross-sectional studies. Our aim was to investigate maternal hemodynamic and cardiovascular adaptations at each trimester of pregnancy in a prospective longitudinal case-control study. Methods: Cardiovascular...

Omni-directional walking is an important part for biped robots. Whereas, the problems of complex model, low stability, low flexibility, etc., existing in walking planning of biped robots, attract interests of many researchers. This paper proposes an adaptive omni-directional walking method with fuzzy...

Gini coefficient and Lorenz curve are increasingly used to examine the inequality of wealth, income, economy, and health. The objective of the current study is to introduce Gini coefficient and Lorenz curve, coefficient of variation (CV), and spatial equilibrium index (SEI) to explore the spatial inequality...

In this note, we establish a law of iterated logarithm for a triangular array of a random number of independent random variables and apply it to obtain laws of iterated logarithm for the sequential nonparametric density estimators. We consider the case of Rosenblatt-Parzen kernel estimators and orthogonal...

This paper proposes and empirically tests a model of the relationship between green supply chain management (GSCM) practices and corporate performance. Based on a literature review, we identified five determinants, namely, environmental commitment, supplier collaboration, supplier assessment, information...

1-dimensional polytropic gas dynamics is integrable for trivial reasons, having 2

We discuss the dynamics of an affinely-rigid body in two dimensions. Translational degrees of freedom are neglected. The special stress is laid on completely integrable models solvable in terms of the separation of variables method.

In this note, we present a result to show that the symplectic structures have been naturally encoded into the Painlevé test. In fact, for every principal balance, there is a symplectic change of dependent variables near movable poles.

Introduction: The aim of this study was to evaluate the microbial contamination of cell phone in dental and engineering schools and also investigating the effect of an antibacterial spray. Method and Materials: A questionnaire was completed by participants, including the pattern of using mobile...

Objectives: Inappropriate antimicrobial use can promote antimicrobial resistance, which is associated with increased patient morbidity and mortality. Identifying the pattern of antimicrobial use can provide data from which targeted antimicrobial stewardship interventions can be made. The primary objective...

Peer-to-peer (P2P) electronic commerce has become increasingly popular over the last few years. This popularity of P2P is due mainly to the many advantages it offers, such as the ease of sharing of computer resources and reducing cost. This paper uses both semi-formal and formal specification methods...

Verification tool for Vienna Development Method (BWDM) is a test case generation tool for the VDM++ specification. The existing BWDM could cause a combinatorial explosion of the generated test cases. To reduce the number of test cases, there is Pairwise Independent Combinatorial Testing Tool (PICT):...

Background: Healthcare providers working in Saudi Arabia come from various nationalities, cultures, and training backgrounds. This study aimed to assess the perceptions of healthcare providers working in Riyadh hospitals about ethical dilemmas and solutions. Methods: This is a cross-sectional study...

Background: Clinical evidence of coronary pressure assessment through a diagnostic catheter is limited. The aim of this study was to assess the difference, safety, and rate of successful measurement of Instantaneous Wave-free Ratio (iFR) through 4Fr and 5Fr diagnostic catheters. Methods: This single-centre...

Major advances in the understanding of genetic iron overload have led to a clarification of the nosology and terminology of the related diseases. The term hemochromatosis should be reserved to the entities where iron overload is related to hepcidin deficiency or hepcidin resistance. The diagnosis of...

Case fatality rate (CFR) is used to calculate mortality burden of COVID-19 under different scenarios, thus informing risk-benefit balance of interventions both pharmaceutical and nonpharmaceutical. However, observed CFR is driven by testing: as more low-risk cases are identified, observed CFR will decline....
