background: intrapulmonary vascular abnormalities associated with liver cirrhosis may result in intrapulmonary right-to-left shunt and hypoxemia. the aim of this study was to use contrast enhanced echocardiography to detect intrapulmonary vascular abnormalities in patients with liver cirrhosis candidates for liver transplantation. methods: one hundred and two adult patients underwent contrast...
Objectives: A functional helpful exercise that tends to correct postural unevenness and endeavours to re-establish lumbo-pelvic mechanics would appear to be beneficial for patients with postural impairment. This study evaluated the effects of right sidelying respiratory left adductor pull back exercise on improving hip biomechanics in participants with a tendency to stand on right side. Method...
Much recent work has focused on the estimation of regression functions in samples which are truncated or censored. Much of this work has focused on the estimation of a parametric regression function with an error distribution of unknown form. While these method relax a strong parametric assumption about which we seldom have a priori information, they still impose a strong parametric assumption ...
This article investigates the nonlinear, steady boundary layer flow and heat transfer of an incompressible Eyring-Powell non-Newtonian fluid from an isothermal sphere with Biot number effects. The transformed conservation equations are solved numerically subject to physically appropriate boundary conditions using a second-order accurate implicit finite-difference Keller Box technique. The influ...
In applied work economists often encounter data generating mechanisms that produce censored or truncated observations. These dgp’s induce a probability distribution on the realized observations that differs from the underlying distribution for which inference is to be made. If this dichotomy between the target and realized populations is not taken into account, statistical inference can be seve...
Background & Aims: Parkinsonism occurs in all races. Its prevalence in the United States and Western Europe is 2.1 persons per 1,000 populations. Approximately one third of patients have cognitive problems that often doubles after 4 years in 80% of patients with dementia and Parkinson’s disease (PD) occurs in the final stages. The aim of this study was to determine the relationship between vis...
This paper is designed to give a complete overview of the literature that is available, as it relates to application of the Bayesian analysis model to investigate multiple group nonlinear structural equation models, also known as SEMs, including those having ordered categorical, dichotomous and categorical-dichotomous mixed variables. It will also work to summarize Bayesian multiple group nonli...
On strong and almost sure local limit theorems for a probabilistic model of the Dickman distribution
Let {Zk}k ≥ 1 denote a sequence of independent Bernoulli random variables defined by P(Zk = 1) 1/k 1− 0) (k and put Tn ≔ ∑1 ≤ k n kZk. It is known that Tn/n convergesweakly to real variable D with density proportional the Dickman function, delay-differential equation uϱ ′ (u) + ϱ(u − 0 (u > initial condition ϱ(u) 1(0 u 1). Improving on earlier work, we propose asymptotic formulae remainders for...
