For decision makers, the data property has a direct influence on the selection of decision making approaches and the reliability of decision results. Because of the complexity and diversity of practical decision data, some traditional decision approaches are not very good at reflecting the actual problem....

We have introduced several kinds of similarity measure and proposed a method for identifying the same languages involved in two language classification trees. Several unknown parameters are used there and need to be set to constant values. This paper aims to determine all the values of these parameters...

We say that an indecomposable Cartan matrix A with entries in the ground field is almost affine if the Lie (super)algebra determined by it is not finite dimensional or affine (Kac–Moody) but the Lie sub(super)algebra determined by any submatrix of A, obtained by striking out any row and any column intersecting...

AS gradient reflects the vascular ageing. The aim of the study: To evaluate the associations between 24-h central PP and parameters of...

Objectives: Cardiovascular disease is a leading cause of death in multiple sclerosis (MS), and recent data showed that subclinical markers of atherosclerosis are higher in MS as well. Prevalence of MS in men is much lower than in women, but their prognosis is much worse. Men with MS also have higher...

This paper proposes a decision support process for incomplete hesitant fuzzy preference relations (HFPRs). First, we present a revised definition of HFPRs, in which the values are not ordered for the hesitant fuzzy element. Second, we propose a method to normalize the HFPRs and estimate the missing elements...

Varicella zoster virus (VZV) reactivation after autologous hematopoietic cell transplantation (auto-HCT) may be observed in a quarter of patients. Currently, prophylactic use of acyclovir 800 mg twice daily or valacyclovir 500 mg twice daily is recommended for prophylaxis against VZV reactivation for...

The evaluation of urban vulnerability is of great significance to improve the quality of urbanization. An urban vulnerability index system was developed from four aspects of population vulnerability, economic vulnerability, social vulnerability and ecological vulnerability. The Spatial and temporal patterns...

National Center for High-performance Computing (NCHC) built a render farm that provides a platform for the industry to render their work in a much more efficient timeframe, allowing for both central processing unit (CPU) and graphics processing unit (GPU) rendering. The throughput has also been greatly...

Through this chapter, we introduce a new class of two-piece asymmetric normal distribution suitable for asymmetric and plurimodal situations. We study some important aspects of this distribution by deriving explicit expressions for its distribution function, characteristic function, reliability measures...

Background: Although emerging evidence suggests that vascular calcification constitutes an active process sharing common features with bone formation, several aspects of this process in human coronary artery calcification are still poorly understood. We therefore investigated the expression of key bone...

Then, employing the dynamic simulation software ADAMS, the virtual prototype model of the separation device is established, and the whole process of on-orbit...

Background: Systemic arterial hypertension (SAH) is one of the major risk factors related to the development of cardiovascular diseases (CVD). Sodium intake is linked to elevated blood pressure and can be estimated by 24-h urinary sodium excretion. The objective of this study was to correlate 24 h urinary...

Acute inflammation is associated with increased risk for cardiovascular events and leads to reductions in conduit artery (flow-mediated dilation, FMD) and resistance vessel endothelial function. Whether this dysfunction during acute inflammation is further transmitted down the arterial tree to the microvasculature,...

Aim: Stroke is a frequent and feared complication in patients with type 2 diabetes. Arterial stiffness may improve current suboptimal risk prediction of stroke. However, studies in diabetes populations are lacking. We investigated the association between arterial stiffness progression (carotid-femoral...
