Mixed models are widely used to analyze longitudinal data. In their conventional formulation as linear mixed models (LMMs) and generalized LMMs (GLMMs), a commonly indispensable assumption in settings involving longitudinal non-Gaussian data is that the longitudinal observations from subjects are conditionally independent, given subject-specific random effects. Although conventional Gaussian...

Backgrounds: Thallium-201 is produced through 203Tl (p, 3n) 201pb 201Tl reaction by cyclotron. This radioisotope has known as one of the cyclotron radioisotopes which is used for myocardial perfusion in the coronary artery disease, Tl-201 after chemical purification and quality control in the form of 201Tl-chlorid is ready to send to the hospitals. Materials and methods: In this work the effect...

A growing number of firms today have to cope with the twofold challenge of mass customization (i.e., combining high performance in product customization with high performance in cost, delivery and quality) and green management (i.e., integrating environmental-sustainability principles into businesses). Research on this joint challenge, however, is still limited in the literature. To narrow this...

this study took an epidemiological approach toward the problem of drug addiction in tehran. the subjects were 300 addicts chosen on the basis of stratified random selection out of the population of 3627 prisoners who were all proven addicts and sentenced to imprisonment by the court in the year 1370. a descriptive survey showed that drug addiction generally, and heroin addiction specifically, i...

Concurrency control in object based systems is a new area of research that has only just begun to be addressed. Recent work has proposed using object level locking but this may be unnecessarily restrictive. Data level locking within an object increases concurrency but also introduces substantial lock overhead that makes the approach impractical. This paper proposes using a new approach applying...

Many abstractions of program dependences have already been proposed, such as the Dependence Distance, the Dependence Direction Vector, the Dependence Level or the Dependence Cone. These diierent abstractions have diierent precisions. The minimal abstraction associated to a transformation is the abstraction that contains the minimal amount of information necessary to decide when such a transform...

Currently, two main approaches to data dependence of EFSM(Extended Finite State Machine) haven’t refined intra-transition data dependence, instead they consider that every definition variable in a transition depends on all the use variables (including condition variables). For data dependence of a specific definition variable, not only the relevant use variables but also the irrelevant use vari...
