Background: Transient ischemic attacks and stroke are commonly caused by vulnerable plaques in the carotid bulb. Noninvasive ultrasound imaging techniques, revealing spatial inhomogeneities in strain distribution, could possibly improve the timely diagnosis of plaque at risk of rupturing. Methods: In...

It is known that telomere length (TL) shortening is a marker of cell aging, which accelerated and progresses in type 2 diabetes mellitus (T2DM), despite the patient’s age, leading to the vascular aging. The aim of the study was to compare the vascular and cellular aging in patients with and without...

Vulnerability analysis is a key step of risk analysis of natural disaster. Based on information diffusion theory and incomplete information, it analyzes the changes of the affected population in urban flood and identifies the function relationship between the hazard (rainstorm) and disaster-bearing body...

Macro-anomalies are so complex that it is difficult to carry out the systematic quantitative analysis macro-anomalies because it is lack of measure space. It’s more difficult to find the relationship between micro-anomalies and earthquakes. In the paper, the theory system of macro-anomalies group’s measure...

In this paper, a novel self-organizing map (SOM) named “One-D-R-A-G-SOM” is proposed. It is a kind of one dimensional ring type growing SOM using asymmetric neighborhood function. As the topology of one dimensional ring type feature map is more suitable to increase or decrease the number of units, and...

In this study, a deep Group Method of Data Handling (GMDH)-type neural network using principal component-regression is applied to the medical image recognition of the heart regions. The deep GMDH-type neural network algorithm can organize the neural network architecture with many hidden layers fitting...

We reduce planar measure-preserving rational maps over finite fields, and study their discrete dynamics. We show that application to the orbit analysis over these fields of the Hasse-Weil bound for the number of points on an algebraic curve gives a strong indication of the existence of an integral for...

An integrable discretization of an inhomogeneous Volterra lattice is introduced. Some aspects of dynamics of a soliton affected by a random force are discussed.

In this paper we apply truncated Painleve expansions to the Lax pair of a PDE to derive gauge Backlund transformations of this equation. It allows us to construct an algorithmic method to derive solutions by starting from the simplest one. Actually, we use this method to obtain an infinite set of lump...

Nepal is highly vulnerable to natural and human induced disasters. Complex geology, variable climatic conditions, active tectonic processes, rapid urbanization, unplanned settlements, lack of public awareness, increasing population, weak economic condition and low literacy rate have made her vulnerable...

Reinforcement learning (RL) aims to resolve the sequential decision-making under uncertainty problem where an agent needs to interact with an unknown environment with the expectation of optimising the cumulative long-term reward. Many real-world problems could benefit from RL, e.g., industrial robotics,...

Background: The HIV epidemic remains a public health problem with rising tuberculosis (TB) numbers around the world. Antiretroviral (ARV) therapy (ART) is essential to increase the survival of patients with TB–HIV coinfection. The aim of this study is to investigate the effect of ARV treatment initiation...

Catheter-associated Urinary Tract Infection (CAUTI) has been studied worldwide as part of device-related healthcare infection. CAUTI is one of the most commonly reported infections in the literature, which occurs during clinical practice in Intensive Care Units (ICUs) and non-ICU departments. Many studies...

In this paper, we introduce periodically correlated space-time autoregressive processes with values in Hilbert spaces. The existence conditions and the strong law of large numbers are established. Moreover, we present an estimator for the autocorrelation parameter of such processes.

Systolic pressure, Ps, and pulse pressure, PP, are determined by heart and arterial system. We here compare systemic arterial system characterizations alone, and mention their use and limitations (aspects). 1.Peripheral resistance, Rp. Required: Mean Pressure and Cardiac Output; Characterization:...

Brachial artery flow-mediated dilation (FMD) is the most widely used technique for assessing endothelial function in humans. FMD is reduced in the presence of cardiovascular risk factors and diseases and it is an independent predictor of events. However, its major limitation is the relatively low reproducibility....

Background. Arterial stiffness is associated with an increased risk of cardiovascular disease (CVD) and carotid-femoral pulse wave velocity (cfPWV) is considered as the ‘gold standard’ measurement method. However cfPWV does not assess the stiffness of the proximal aorta and its sensitivity at higher...

Background: The Valsalva manoeuvre (VM) is a physiological manoeuvre capable of generating profound changes in venous return. Although its physiology has been extensively described, the predominant focus has been on dynamic effects on cardiac preload with subsequent impact on cardiac output. However,...

Arterial stiffness (AS) is generally measured by regional arterial pulse wave velocity (rPWV) or locally by arterial distensibility. Although often used interchangeably, some studies show a weak correlation between these well accepted AS index depending on population. Thus, we aim to investigate in an...

Background: Aortic elasticity properties (aortic distensibility, compliance, elastic modulus, and stiffness index) can be evaluated by cross-sectional thoracic aorta areas measurements at 2 times of the cardiac cycle (peak systolic and end-diastolic phases) with PC-cine MRI series. Pulse wave velocity...

Background. Evidence-based thresholds for risk stratification based on pulse pressure (PP) are currently unavailable. Methods. To derive outcome-driven thresholds for the 24-h ambulatory PP, we analyzed 9938 people randomly recruited from 11 populations (47.3% women). After age stratification (<60...

In this paper, a new extension of cumulative residual entropy is proposed. It contain the generalized cumulative residual entropy introduced by Psarrakos and Navarro (2013) and is related with the k-record values. We also consider a dynamic version of this new cumulative residual entropy using the residual...

The use of unmanned aerial vehicles (UAVs) in the construction industry is swiftly growing worldwide. UAVs are changing the way construction companies do business. Contractors are increasingly using camera-mounted UAVs to monitor the full range of activities. Rapid advances in camera, sensing, aeronautics,...

We construct all partial Noether operators corresponding to a partial agrangian for a system with two degrees of freedom. Then all the first integrals are obtained explicitly by utilizing a Noether-like theorem with the help of the partial Noether operators. We show how the first integrals can be constructed...

By the use of geometric methods for linearizing systems of second-order cubically semi-linear ordinary differential equations and the conditional linearizability of third-order quintically semi-linear ordinary differential equations, we extend to the fourth-order by differentiating the third-order conditionally...

The methods of [vdP-Sa, vdP1, vdP2] are applied to the fourth Painlevéequation. One obtains a Riemann–Hilbert correspondence between moduli spaces of rank two connections on ℙ1 and moduli spaces for the monodromy data. The moduli spaces for these connections are identified with Okamoto–Painlevé varieties...

Multi-attribute group emergency decision making (MAGEDM) has become a valuable research topic in the last few years due to its effectiveness and reliability in dealing with real-world emergency events (EEs). Dynamic evolution and uncertain information are remarkable features of EEs. The former means...
