We study non-trivial deformations of the natural action of the Lie algebra Vect(Rn ) on the space of differential forms on Rn . We calculate abstractions for integrability of ifinitesimal multi-parameter deformations and determine the commutative associative algebra corresponding to the miniversal deformation...

Evaluation is a process that analyzes elements in order to achieve different objectives such as quality inspection, marketing and other fields in industrial companies. This paper focuses on sensory evaluation where the evaluated items are assessed by a panel of experts according to the knowledge acquired...

The term Soft Computing was coined by L.A. Zadeh in the early 90's. Since that time many researchers have tried to define it considering different approaches: main constituents, properties, abilities, etc. In addition, the term Computational Intelligence has also gained popularity having a somehow quite...

We often make decisions on the things we like, dislike, or even don’t care about. However, taking the right decisions becomes relatively difficult from a variety of items from different sources. Recommender systems are intelligent decision support software tools that help users to discover items that...

In this paper, we consider a general form for the underlying distribution and a general conjugate prior, and develop a general procedure for Bayesian estimation based on an observed multiply Type-II censored sample. The problem of predicting the order statistics from a future sample are also discussed...

This manuscript brings attention to inaccurate epidemiological concepts that emerged during the COVID-19 pandemic. In social media and scientific journals, some wrong references were given to a “normal epidemic curve” and also to a “log-normal curve/distribution”. For many years, textbooks and courses...

Objective: Patients with ankylosing spondylitis (AS) are at increased risk of CVD. The etiological mechanism or how to reduce risk is not known. Exercise can reduce CV risk in the general population. The objective was to test whether high intensity aerobic exercise reduces central arterial stiffness. Methods:...

Objective: To examine changes in ventriculo-arterial coupling (VAC) and left ventricular systolic function (LVFSYS) after a period of intensified antihypertensive treatment in patients with hypertension and type-2-diabetes. Methods: Patients were categorized as controlled- (CH), uncontrolled- (UH) or...

Objectives: We recently found significant age-related increases in brachial-to-radial systolic blood pressure amplification (Bra-Rad-SBPAmp), and this has implications for correct central SBP estimation. Patients with type 2 diabetes mellitus (T2DM) have vascular irregularities that may alter Bra-Rad-SBPAmp...

A novel algorithm of audio aggregation watermarking was proposed in this paper for copyright protection. The algorithm not only protects copyright of a single audio in audio aggregation but also protects copyright of the whole audio aggregation. The experimental results showed the watermark of aggregate...

The problem of construction of boundary conditions for nonlinear equations compatible with their higher symmetries is considered. Boundary conditions for the sineGordon, Zhiber­Shabat and KdV equations are discussed. New examples are found for the JS equation.

We show that for a class of boundary value problems, the space of initial functions can be stratified dependently on the limit behavior (as the time variable tends to infinity) of solutions. Using known results on universal phenomena appearing in bifurcations of one parameter families of one-dimensional...

It is shown how pseudoconstants of the Liouville-type equations can be exploited as a tool for construction of the Bäcklund transformations. Several new examples of such transformations are found. In particular we obtained the Bäcklund transformations for a pair of three-component analogs of the dispersive...

We report the recursion operators for a class of symmetry integrable evolution equations of third order which admit fourth-order recursion operators. Under the given assumptions we obtain the complete list of equations, one of which is the well-known Krichever-Novikov equation.

This paper introduces a novel ensemble learning approach based on recurrent radial basis function networks (RRBFN) for time series prediction with the aim of increasing the prediction accuracy. Standing for the base learner in this ensemble, the adaptive recurrent network proposed is based on the nonlinear...

Objective: To explore associations of perinatal and family factors with preadolescence overweight and obesity in a sample of Greek schoolchildren. Methods: A nationwide cross-sectional study among 2093 students (10.9 ± 0.72 years, 44.9% boys) and their parents were conducted. Anthropometric (e.g., height,...

Discussing the technological innovation efficiency of big data enterprises and carrying out in-depth research on big data enterprises will help to accurately evaluate the development status of big data industry and guide the development of big data industry. This paper uses DEA-BCC model to evaluate...

Introduction: Measurement of Blood Pressure (BP) in children provides insight into future Cardiovascular Disease (CVD) risk. Objective: To examine the feasibility and reliability of home BP monitoring in children with Autism Spectrum Disorder (ASD) and compare to office BP measurement. Methods: Seven...

We study the shape of inflated surfaces introduced in [3] and [12]. More precisely, we analyze profiles of surfaces obtained by inflating a convex polyhedron, or more generally an almost everywhere flat surface, with a symmetry plane. We show that such profiles are in a one-parameter family of curves...

We innovate an educational toy to play the English learning system. The proposed system uses a Raspberry Pi and two Near Field Communication (NFC) readers. The user can learn English words in three steps by using our system. First, NFC tags are presented corresponding to English words and illustrations,...

Aortic pulse wave velocity (PWV) is a measure of vascular organ damage. After a cardiac event, patients can be proposed to follow an educational and exercise program to prevent future events and improve their cardiovascular risk. We hypothesized that the improvement of aerobic performance will depend...

Objectives: The reference standard for non-invasive central blood pressure (BP) measurement is radial tonometry calibrated using brachial BP. Brachial-to-radial-systolic-BP-amplification (Bra-Rad-SBPAmp) may introduce error into central BP measurement but the magnitude of Bra-Rad-SBPAmp in healthy people...

Background: A hypertensive response to exercise (HRE) at moderate intensity is an independent risk factor for cardiovascular events and mortality, but the underlying mechanisms are unknown. This study sought to determine the haemodynamic predictors of exercise blood pressure (BP) and an HRE. Methods:...
