We give a short review of recent results on L2 -cohomology of infinite configuration spaces equipped with Poisson measures.

By computing certain cohomology of Vect(M ) of smooth vector fields we prove that on 1-dimensional manifolds M there is no quantization map intertwining the action of non-pro jective embeddings of the Lie algebra sl(2) into the Lie algebra Vect(M ). Contrariwise, for pro jective embeddings sl(2)-equivariant...

The similarity solution to Prandtl’s boundary layer equations for two-dimensional and radial flows with vanishing or constant mainstream velocity gives rise to a third-order ordinary differential equation which depends on a parameter ?. For special values of ? the third-order ordinary differential equation...

An overview is presented of recent progress on the relation between the pressure at the bottom of the flat water bed and the elevation of the free water boundary within the context of the one-dimensional, irrotational water wave problem. We present five different approaches to this problem. All are compared...

The purpose of this work is to perform group classification of a coupled system of partial differential equations (PDEs) modeling a flow in collapsible tubes. This system of PDEs contains unknown functions of the dependent variables whose forms are specified via the classification with respect to subalgebras...

Objective: To determine whether HIV status and knowledge of mother-to-child-transmission (MTCT) of HIV are associated with antenatal care (ANC) use. Methods: Data were obtained from the 2011 Ethiopia Demographic and Health Survey among women aged 15–49 years who agreed to HIV testing and who reported...

This study aims to assess the prevalence of stress and burnout among preclinical medical students in a private university in Beirut, Lebanon, and evaluate the association between extracurricular involvement and stress and burnout relief in preclinical medical students. A cross-sectional survey was conducted...

Due to the long and narrow regional characteristics of Inner Mongolia, there are obvious climatic differences between the east and the west, and various meteorological factors have different influences on the development and utilization of solar energy. The abundance and stability index of solar energy...

Background: Masked hypertension (MH) independently predicts mortality but cannot be diagnosed from clinic blood pressure (BP). We sought to determine if MH could be identified from BP or pressure waveform analysis (PWA) at rest or during low intensity exercise. Methodology: Brachial and estimated central...

Both endothelial dysfunction and arterial stiffness are considered as independent predictors of cardiovascular mortality, but their interrelationship has been poorly explored. Therefore we evaluated the relationship between endothelial function and pulse wave velocity (PWV) in essential hypertensive...

Background: Paget’s disease of bone (PDB) is a common disorder characterised by increased, disorganised bone turnover in affected areas with overgrowth of immature woven bone. An increased cardiovascular risk has been reported in some studies of PDB, possibly related to arterial wall calcifications....

Background: Population studies have indicated that both the presence of osteoporosis and serum levels of calcium are associated with an increased risk of cardiovascular disease. Objective: To investigate the association between bone loss, calcium intake and levels of the reactive hyperemia index (RHI)...

In this paper, the moment-based, maximum likelihood and Bayes estimators for the unknown parameter of the Lindley model based on Type II censored data are discussed. The expectation maximization (EM) algorithm and direct maximization methods are used to obtained the maximum likelihood estimator (MLE)....

In hydrological statistics, the traditional assessment of goodness of fit test is interested in the testing precision to the sample generated from supposed PDF. However, the ability to reject the hypotheses when the supposed PDF is different from real PDF should be also emphasized. In addition, the sensitivity...

Confined space is a special working place. To ensure the safety, the forced ventilation must be carried out before entering the confined space. In this paper, ventilation process in municipal heating confine space is simulated by CFD numerical simulation method, and the distribution of temperature, oxygen...

Separable coordinate systems are introduced in complex and real four-dimensional flat spaces. We use maximal Abelian subgroups to generate coordinate systems with a maximal number of ignorable variables. The results are presented (also graphically) in terms of subgroup chains. Finally the explicit solutions...

The inhomogeneity of the media or the external forces usually destroy the integrability of a system. We propose a systematic construction of a class of quantum models, which retains their exact integrability inspite of their explicit inhomogeneity. Such models include variable mass sine-Gordon model,...

In urban areas, people’s life may be threatened by disasters such as earthquakes. To reduce the life risks, efficient responses including evacuation are of critical importance. However, a drill evacuation appears impossible; simulation is thus used to examine the effectiveness of an evacuation plan....

Bayesian networks have been widely used for classification problems. These models, structure of the network and/or its parameters (probability distributions), are usually built from a data set. Sometimes we do not have information about all the possible values of the class variable, e.g. data about a...

Episodes of adenolymphangitis (ADL) are a recurrent clinical aspect of lymphatic filariasis (LF) and a risk factor for progression of lymphedema. Inter-digital entry lesions, often found on the web spaces between the toes of those suffering from lymphedema, have been shown to contribute to the occurrence...

Ever rising prevalence of Cardiovascular Diseases (CVD) is a major challenge for the health sector in Bangladesh. This study aimed to explore the prevalence of CVD and sociodemographic and lifestyle factors associated with it in Bangladesh. The data were collected through a cross-sectional survey following...

Plasminogen activator inhibitor (PAI-1) is the key inhibitor of the fibrinolytic system, modulating cellular responses associated with vascular remodeling. Elevated plasma PAI-1 has been positively correlated to systolic- and diastolic blood pressure, measured in the brachial artery, and is increased...

There is some evidence that in MetS increase of arterial stiffness may be distributed over muscular and the elastic arteries not uniformly. The purpose of this study was to examine the association between the MS and arterial stiffness of both elastic and muscular arteries in middle aged individuals. Methods:...

Introduction: Aortic pulse wave velocity (aPWV) may measure vascular structure and function (distensibility) more precisely than blood pressure (BP). Few data exist on arterial distensibility in infancy; none on the effects of malaria in African children. Methods: Healthy women with singleton pregnancies...

TFVIS (transitions and flow visualization) can perform the visualization of data transitions and the visualization of execution flows. The visualization of data transitions shows the flow of variable renewals in executing programs. It becomes easier to grasp the behavior in executing the programs whose...

This paper studies the load balancing problem in distributed systems designed for massively multiplayer online role-playing games (MMORPGs). More concretely, we consider a distributed system of master- worker type in which each worker is associated with a particular region in the game field, and propose...

Using the ultraviolet observation data of Huangshan Scenic area from March 2017 to February 2018, this paper analyzes the relationship between the daily, monthly and seasonal variation characteristics of ultraviolet radiation intensity and its related meteorological elements. The results show that the...

In this paper, we shall firstly illustrate why we should introduce set-valued stochastic integrals, and then we shall discuss some properties of set-valued stochastic processes and the relation between a set-valued stochastic process and its selection set. After recalling the Aumann type definition of...

Lie point symmetry group classification of a scalar stochastic differential equation (SDE) with one-dimensional Brownian motion is presented. First we prove that the admitted symmetry group is at most three-dimensional. Then the classification is carried out with the help of Lie algebra realizations...
