Background: Aberrant renovascular anatomy has been reported to occur in up to 80% of patients with Essential Hypertension (EH). In more than 20% of subjects, at least one kidney is found to be supplied by more than one artery arising from the aorta (1). Methods: We analysed reports of renal Angiographic...

Objectives: Parameters associated with elevated arterial stiffness and structural vascular remodeling, like aortic pulse wave velocity, have been identified as important contributors to predict cardiovascular outcome in end stage renal disease but less is known about their value in early stages of chronic...

The solar photovoltaic battery is a very important new type of renewable distributed energy. But its output power is directly affected by the light intensity and temperature. Its voltage-current characteristics have obvious nonlinear features. Therefore, a new MPPT technology based on the model predictive...

In this paper, the problem of testing exponentiality against used better than aged in convex ordering classes of life distributions is investigated. For this property a nonparametric test is presented based on kernel method. The test is presented for complete and right censored data. Furthermore, Pitman's...

It takes much time to find the cause of a bug in debugging of programs. Finding the cause of a bug needs to comprehend a flow and data transitions in executing programs. It is difficult to grasp behavior in executing the programs whose behavior is unexpected by a bug. We propose a visualizing method...

In this article we present an approach designed to solve a real world problem: the Anesthesiology Nurse Scheduling Problem (ANSP) at a public French hospital. The anesthesiology nurses are one of the most shared resources in the hospital and we attempt to find a fair/balanced schedule for them, taking...

A video is analyzed by image processing and the feature parameters of facial expressions and movements, which are extracted in the mouth area. The feature parameter for expressing facial expressions is defined as the average of the facial expression intensity. The parameter for expressing movement of...

We study solitons arising in a system describing the interaction of a two-dimensional discrete hexagonal lattice with an additional electron field (or, in general, an exciton field). We assume that this interaction is electron-phonon-like. In our previous paper [4] we have studied the existence of two-dimensional...

The idea of introducing coordinate transformations to simplify the analytic expression of a general problem is a powerful one. Symmetry and differential equations have been close partners since the time of the founding masters, namely, Sophus Lie (1842­1899), and his disciples. To this days, symmetry...

Rescue robots are expected to perform works in hazardous areas. However, when the robot runs on a rough terrain, fatal rollover falling sometimes occurs. Therefore, we propose a tumble-risk-assessment system, which calculates a normalized energy stability margin by using a 3D depth sensor. Moreover,...

Background: Central systolic blood pressure (cSBP) may be more predictive of cardiovascular events than brachial BP. Therefore, non-invasive methods of determining central BP, which are suitable for routine clinical use, are required. The aim of this study was to compare estimates of cSBP provided by...

The ranked-set sampling technique has been generalized so that a more efficient estimator may be obtained. This technique allows more than one unit from each set to be quantified. Consequently, the number of units to be sampled may be reduced significantly and as a result, the corresponding cost would...

Long-term allogeneic hematopoietic cell transplant (allo-HCT) survivors suffer an elevated risk of coronary heart disease (CHD). We conducted a prospective, nonrandomized, cross-sectional study to screen asymptomatic survivors at a single allo-HCT center using cardiac computed tomography (CT) involving...

A new geometric view of homogeneous isotropic turbulence is contemplated employing the two-point velocity correlation tensor of the velocity fluctuations. We show that this correlation tensor generates a family of pseudo-Riemannian metrics. This enables us to specify the geometry of a singled out Eulerian...

It is commonly assumed that pressure and flow in the arteries are purely the result of forward and backward travelling waves. We will show that various observations of arterial behaviour are difficult to explain using this assumption. In particular we will look at what happens to arterial pressure under...

Blood pressure variability (BPV) is due to complex interaction of cardiac and vascular factors and is influenced significantly by baroreceptor control. The cardiovagal baroreflex sensitivity (BRS) has been shown to depend on vascular compliance and this may explain recent epidemiological association...

Background: Ambulatory Blood Pressure (BP) as well as central BP are better predictors for overall cardiovascular risk and mortality than brachial BP. Renal Denervation (RDN) has been shown to reduce office brachial and central BP as well as ambulatory brachial BP, but data on central ambulatory BP are...

Introduction: Intravascular Elastography has proven to be a sensitive tool to identify vulnerable plaques in coronary arteries. It is a technique to assess the deformation (strain) due to the pulsatile blood pressure of the vessel wall and plaque. However, for screening asymptomatic patients, a noninvasive...

Introduction: Central Pressure (PC) has shown to be more reliable in cardiovascular (CV) mortality (1); Salt intake and excretion seems to lead to an increase in this pulsatile component of the arterial flow (2, 3). C entral Pulse Pressure (PPc) data is very few. Methods: A population-based cross-sectional...

The ground-breaking developments in non-invasive imaging over the last 50 years has provided a range of exciting new tools for physiologists and clinicians interested in large artery structure and function. The main focus of my lecture will be on MRI and PET/CT. MRI can be used in a number of different...

The crisis management literature offers a host of theoretical treatises that are relevant to crisis threat assessment in public administrations; however, these insights remain non-cumulative, non-consolidated, and unstructured in a field of individual contributions. Using existing literature regarding...

The mechanism of landslide hazard in weathering crust of granites in south china was chosen as our research object. Landslides, as a common geo-hazard, can result in huge economic losses and enormous casualties in mountainous regions of the world. Therefore, the mechanism of landslide hazard has become...

For software development using Formal Methods, we have developed a prototype of the boundary value test case automatic generation tool BWDM. The main two topics of our tool are (1) automatically generation of test cases and (2) boundary value analysis. Our tool improves the efficiency of software testing...

The traffic in the counties of Guizhou is inconvenient and the economic location is remote. How to transform the characteristics of natural resources and national cultural resources into economic advantages? This is the key of this paper. In this paper, the tourism industry of 50 poverty-stricken counties...

We describe realizations of the colour analogue of the Heisenberg Lie algebra by power series in non-commuting indeterminates satisfying Heisenberg's canonical commutation relations of quantum mechanics. The obtained formulas are used to construct new operator representations of the colour Heisenberg...

Some classical types of nonlinear periodic wave motion are studied in special coodinates. In the case of cylinder coordinates, the usual perturbation techniques leads to the overdetermined systems of linear algebraic equations for unknown coefficients whose compatibility is key step of the investigation....

An extension of the classic Enneper­Weierstrass representation for conformally prametrised surfaces in multi-dimensional spaces is presented. This is based on low dimensional CP1 and CP2 sigma models which allow the study of the constant mean curvature (CMC) surfaces immersed into Euclidean 3- and 8-dimensional...

The symmetry approach to the determination of Jacobi's last multiplier is inverted to provide a source of additional symmetries for the Euler­Poinsot system. These addtional symmetries are nonlocal. They provide the symmetries for the representation of the complete symmetry group of the system.

There are always some people who experienced or studied the risks of daily life. Based on that, in this paper, we proposed a new concept Internet of intelligences (IOI), which consists of intelligent agents, the Internet and a mathematics model. An IOI collects and processes the information provided...

The first part of this work is a review of the point classification of second order ODEs done by Ruslan Sharipov. His works were published in 1997–1998 in the Electronic Archive at LANL. The second part is an application of this classification to Painlevé equations. In particular, it allows us to solve...

The large arterial system and the microcirculatory network are generally studied as separated entities. We aimed to establish a link between the remodelling of microcirculatory and arterial blood pressure. Experimental: Pre-hypertensive spontaneously hypertensive rats SHRs were maintained under hypoxic...

A trace contains sample points, some of which contain useful information that can be used to obtain a key in side-channel attacks. We used public datasets from the ANSSI SCA Database (ASCAD) as well as SM4 traces to learn whether a trace consisting of Points of Interest (POIs) have a positive effect...

We prove simplicity of algebras in the title, and compute their δ-derivations and symmetric associative forms.

Nonlinear Schrödinger equations with spatial modulation associated with integrable Hamiltonian systems of Ermakov-Ray-Reid type are introduced. An algorithmic procedure is presented which exploits invariants of motion to construct exact wave packet representations with potential applications in a wide...

Cutaneous erythema is used in diagnosis and response assessment of cutaneous chronic graft-versus-host disease (cGVHD). The development of objective erythema evaluation methods remains a challenge. We used a pre-trained neural network to segment cGVHD erythema by detecting changes relative to a patient’s...

In chemical plants and other process industries, desired conditions are achieved by adjusting controllers. However, it is difficult to obtain the desired control response because most of the controllers use fixed Proportional-Integral-Differential (PID) control. On the other hand, the internal model...

Proteomics has made tremendous progress over the recent years. Initiatives, such as the Human Protein Atlas project, provide a great resource by capturing the in vivo location of proteins in different tissues and by making these data publically available (www.proteinatlas.org). Apart from the inherent...

A long-standing question is whether pregnant females, who bear an increased biological stress, experience exacerbated cardiovascular responses during physiological challenge. At rest, pregnant females have reduced blood pressure, increased cardiac output, heart rate and stroke volume (1), with reported...

Aortic stiffness is now established as an independent marker of cardiovascular aging and cardiovascular risk. However, the specific role of the proximal aorta, specifically the ascending aorta, remains understudied. Magnetic resonance imaging (MRI), a non invasive technique has recently been proposed...

Background and Objectives: It is known that physical activity is inversely associated with arterial stiffness in healthy adults 1. Data regarding the effect of physical activity on PPA is limited. Such data is of importance especially in South Africa, where alarming rates of physical inactivity have...
