In this paper, some characterization results for exponential distribution are established. The results are concluded in terms of number of observations near of order statistics. It is shown that its probability mass function and its first moment can characterize the exponential distribution. Also, an...

The main purpose of this grounded theory research was to explore Diabetic Patients’ (DPs) experiences related to their chronic illness in the light of the Health Belief Model (HBM). Diabetic mellitus II is a grave public health concern, and its management is the cornerstone to avoid life-threatening...

In this paper, we are concerned with a robustifying high-dimensional (RHD) structured estimation in finite mixture of multinomial models. This method has been used in many applications that often involve outliers and data corruption. Thus, we introduce a class of the multinomial logistic mixture models...

The aphrodisiac property of Eurycoma longifolia has led to an increase in the demand for its Herbal Medicinal Products (HMPs). However, the efficiency of such HMPs depends on the usage of their genuine raw materials. The conventional methods cannot identify species in processed form. The authentication...

Diffuse large B-cell lymphoma (DLBCL) is a biologically and clinically heterogeneous disease. Despite good responses to standard of care frontline chemoimmunotherapy, the prognosis of relapsed/refractory (R/R) patients remains obscured by the possible inadequate responses to salvage therapy, eligibility...

In this paper we are intersted in studying the existence of a First integral and the non-existence of limit cycles of rational Kolmogorov systems of the form {x′=x(P(x,y)+R(x,y)S(x,y)),y′=y(Q(x,y)+R(x,y)S(x,y)), where P (x, y) , Q (x, y) , R (x, y) , S (x, y) are homogeneous polynomials of degree...

This paper aims to extract valuable information automatically from medical images to assist doctors in chest X-ray image interpretation. Considering the different linguistic and visual...

Coronary artery diseases are the most common type of cardiovascular diseases and have an increasing prevalence with age. Epidemiological studies demonstrated that coronary failure is associated with several pathologies (as atherosclerosis, hypertension, diabetes, endothelial dysfunction, renal insufficiency)....

The arterial tree exhibits a complex spatio-temporal wave pattern, whose healthy behaviour depends on a balance between mechanical and geometrical properties. Several clinical studies demonstrated that this balance progressively breaks down during ageing, when the aorta stiffens and remodels. This dual...

Increased blood pressure represents a major cardiovascular risk factor for western populations. Usually blood pressure is measured peripherally, but current evidence suggested that central blood pressure better predicts cardiovascular events. However, central blood pressure measurement is not feasible...

Setting up new strategies to prevent the growth and fatal rupture of aneurysms remains a challenge. The rat xenograft model of abdominal aortic aneurysm (AAA) has been used to develop gene and cell therapies with the aim of countering the expansion of the diseased arterial wall. It is of primary importance...

This paper examined the effects of the social context (media communication, face-to-face communication, and friend and kinship network) on pre decisional processes of individual protective action. A two-stage survey was carried out aimed at residents in Beijing communities in half a year, and then the...

In order to communicate in cipher over IP multicast, each of joining and leaving participants causes renewing keys. Moreover, the number of renewed keys depends on the key management system. LKH, one of the key management systems, uses a tree structure to manage keys to share with participants. Every...

With the rapid development of rural micro-credit, whether the "agriculture, rural areas and farmers" problems have been effectively solved, whether the credit risk has been effectively controlled, these have become the focus of our attention to the rural economic environment. The main content of this...

In this article, we generalize a construction of graded q-differential algebra with ternary differential satisfying the property d3 = 0 and q-Leibniz rule on the non-coordinate case, that is on the case where the differentials of generators of underlying algebra do not coincide with generators of bimodule...

The monodromies are calculated and are expressed as hyperelliptic integrals. Applications to the spectral problem for the...

Integrability of differential constraints arising from the singularity analysis of two (1+1)-dimensional second-order evolution equations is studied. Two nonlinear ordnary differential equations are obtained in this way, which are integrable by quadrtures in spite of very complicated branching of their...

In a scientific domain, learning comprises studying a finite set of principles of the domain and applying them to solve a wide variety of problems. Therefore an intelligent tutoring system in a scientific domain is required to possess an adequate methodology to deal with this principle. We suggest a...

Crisis response can be improved by accounting for differences in risk perception. We confirm that gender individuality can be an important divider by using a case study of agricultural producers. Women were more risk averse and less confident. However, we found less difference than studies have found...

Crises are our new reality. “Black swans” are increasingly becoming the norm; our systems, environments, contexts are structurally prone to crises. Doing more of the same will not be the appropriate way to deal with modern crises: a paradigm shift is needed, based on a more accurate understanding of...

Animal studies have shown that vitamin A plays a role in immunity and protection against infectious diseases. Its role reducing incidence of diarrhea and measles, and childhood mortality is known, but its role in relation to malaria is unclear. Thus, a comprehensive, systematic literature search was...

A novel learning approach for a composite function that can be written in the form of a matrix system of linear equations is introduced in this paper. This learning approach, which is gradient-free, is grounded upon the observation that solving the system of linear equations by manipulating the kernel...

The volatile nature of exchange rates with the advent of floating regimes has received much attention in economic research.

Background: Infection is one of the major threats to Healthcare Workers (HCW) worldwide. It exposes HCW to more than 20 kinds of blood-borne pathogen infections, especially the most severe cases, namely Hepatitis B Virus (HBV), Hepatitis C Virus (HCV), and Human Immunodeficiency Virus (HIV). The impact...

New periodic solutions of signum-Gordon equation are presented. We first find solutions φ0(x, t) defined for (x, t) ∈ ℝ × [0, T ] and satisfying the condition φ0(x, 0) = φ0(x, T ) = 0. Then these solutions are extended to the whole spacetime by using (2.4).

Since aortic pressure cannot be measured noninvasively, pressure signals are often measured at more superficial arteries and a transfer function is applied to obtain a surrogate for the central pressure curve. These transformations are usually derived from measurements in a specific group of subjects...

Estimation of aortic and left ventricular (LV) pressure usually requires measurements that are difficult to acquire during the imaging required to obtain concurrent LV dimensions essential for determination of LV mechanical properties. We describe a novel method for deriving aortic pressure from the...
