For analysis of contingency tables with large sample size, classical approaches using approximate methods have high power. However, when the sample size is small or some cells have frequencies less than 5, classical approaches are so conservative. Also asymptotic behavior may be poor when the table contains...

The Cauchy problem for the Liouville equation with a small perturbation is considered. We are interested in the asymptotics of the perturbed solution under the assumption that one has singularity. The main goal is to study both the asymptotic approximation of the singular lines and the asymptotic approximation...

The different second-order nonlinear partial equations are found that are invariant under the representation D(1 2, 0) D(0, 1 2) of the Poincaré group P(1, 3) and also under conformal group C(1, 3). The some exact solutions are constructed for the one of these equations.

The objective of this study is to assess whether adult children’s migration is associated with overall well-being of left-behind elderly parents in Nepal. A cross-sectional house-to-house survey was conducted among 260 community-dwelling elderly residents of Krishnapur municipality, Nepal. Binary logistic...

The success of allogeneic stem cell transplant is hampered by the development of acute and chronic graft-versus-host disease (GvHD) which has direct impact on treatment-related mortality and morbidity. As a result, T cell depletion through positive selection of CD34+ cells has emerged as a promising...

Introduction: Excessive adipose tissue is associated with adverse metabolic effects and is an important risk factor for chronic diseases. According to the American Heart Association, most cardiovascular events can be prevented by adhering to healthy practices, reflecting cardiovascular health as poor,...

Under-five mortality is a substantial indicator of children’s health, well-being, and consequently, socioeconomic development of a country. The primary focus of this study was to estimate the prevalence and identify the factors associated with under-5 mortality in Nigeria. This research utilized the...

The search for novel natural ingredients has been stimulated by the food and non-food industries, and roots of Pachyrhizus erosus (jicama) emerges as promising crops for industrial production due to its crispy and succulent flesh and high yield. Therefore, jicama starches from Fujian Province (SFJ) and...

Scanning Acoustic Microscopy (SAM) images have a spatial resolution at 1 GHz comparable to conventional optical microscopy. Each pixel in the image can be analysed to determine mechanical properties, allowing their precise correlation with microstructural components of tissue. Although loss of elasticity...

Background: Even after successful treatment of aortic coarctation, a high risk of cardiovascular morbidity and mortality remains. Uncertainty exists on the factors contributing to this increased risk among others the presence of (1) a residual narrowing, leading to an additional resistance in the arterial...

Background: Increased arterial stiffness is associated with a reduced buffering capacity of the large arteries, therefore predisposing the microcirculation to increased flow and pressure pulsatility. However, increased wave reflection may be protective, by reducing the amount of pulsatility transmitted...

Background: Aortic stiffness is clinically important, but measurement can be time consuming. The ‘reflected wave transit time’ (RWTT) is thought to represent aortic stiffness and, since this can be measured quickly by brachial cuff oscillometry, could be a useful new test. This study aimed to compare...

Background: We previously described longitudinal strain gradient named bending strain (BS), along the common carotid artery (CCA) with two distinct patterns (Paini, Stroke 2007, Beaussier, Hypertension 2008): Pattern A (larger radial strain at the plaque level than at adjacent CCA) and its opposite,...

Objectives: While in young subjects, central pressure and flow peaks occur simultaneously and before time to return of reflected pressure (Tr), Tr progressively shifts towards early systole with aging, and eventually occurs before pressure peak. Consequently such parameters along with the corresponding...

Cloud computing services have not been yet deployed widely by the SMEs in Japan. Due to its many advantages, special skills and support techniques for the SMEs need to be developed in order to implement cloud computing services. A research of the relevant literature reveals that virtually no published...

A family of real Hamiltonian forms (RHF) for the special class of affine 1 + dimensional Toda field theories is constructed. Thus the method, proposed in [1] for systems with finite number of degrees of freedom is generalized to infinite-dimensional Hamiltonian systems. We show that each of these RHF...

Quantum Schrödinger equation, describing dynamical spin-interaction of two electrons with external magnetic field, is considered as an object for cybernetic research. Indeed, because of having a possibility to change external magnetic field, we can influence the interaction of particles. The algorithm...

In this paper we prove an extension of the usual freezing trick argument which can be applied to a number of quasi-exactly solvable spin models of Calogero­Sutherland type. In order to illustrate the application of this method we analyze a partially solvable spin chain presenting near-neighbors interactions...

The calculation of the premium cost of an option exchange is usually computed by the different mathematical models that obtain the degree of uncertainty in the financial market by Black-Scholes method though such a degree is inaccurate. In order to improve the management of uncertainty the use of fuzzy...

Decision making is a common process in human activities. Every person or organization needs to make decisions besides dealing with uncertainty and vagueness associated with human cognition. The theory of fuzzy logic provides a mathematical base to model the uncertainities. Hesitant fuzzy linguistic term...

From the viewpoint of preventing dementia, balanced meal, moderate exercise, intellectual activities and social interaction are important. We considered shopping activities were proper to encourage those factors because the activities were intellectual in human daily activities. In this paper, we are...

The Centers for Disease Control and Prevention (CDC) recommends syphilis screening at least annually for sexually active men who have sex with men (MSM). The objective of this study is to assess the frequency of MSM testing for syphilis and how syphilis test results compared with results of rectal gonorrhea...

Tuberculosis (TB) diagnosis in children still remains a challenge in developing countries. We analyze the performance of Xpert MTB/RIF assay for the diagnosis of pediatric TB under programmatic conditions. We retrospectively analyzed the performance of Xpert MTB/RIF assay from February 2016 to March...

Based on a multi-class support vector machine, an urban real estate early warning model is constructed for the Beijing real estate market. The initial indicator system is established based on the historical development of Beijing's real estate market and the selection of real estate early warning...

Despite the recent dramatic progress in acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) therapy, allogeneic transplant remains a mainstay of treatment for patients with acute leukemia. The availability of novel compounds and low intensity chemotherapy regimens made it possible for...

Background: Arterial stiffening is an independent predictor for cardiovascular mortality. Preliminary studies have shown that arterial calcification may have impact on increased vascular stiffness. However, little is known about the role of calcification inhibitor osteoprotegerin (OPG) as an independent...

Background: Chronic inflammatory arthropathies such as rheumatoid arthritis (RA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA) are associated with an increased risk of cardiovascular disease. TNF-α antagonists are previously reported to improve vascular function in these patients and thus...
