In epidemiological research, there exist two prospective cohort study designs, open and fixed cohorts, which can be used to assess the incidence of cancer or other chronic diseases. After a long period of follow-up, attrition rate and increased variance of incidence rate estimation due to a...

In time series problems often arise that involve large discrete solution spaces. It may happen that either searching such spaces cannot be accomplished by exhaustive enumeration or satisfactory methods do not exist which are able to yield the optimal solution for problems of moderate and large...

In this paper, we establish some results on strong convergence for sums and weighted sums of uniformly integrable fuzzy random variables taking values in the space of upper-semicontinuous fuzzy sets in

We study a modification of the canonical model for networks of class I neurons derived by Hoppensteadt and Izhikevich, in which the ‘pulse' emitted by a neuron is smooth rather than a -function. We prove two types of results about synchronization and desynchronization of such networks, the...

Some Grüss type inequalities for two sequences of vectors in terms of the forward difference are given. An application for the Jensen inequality for convex functions defined on inner product spaces is also pointed out

The problem of periodic flow of an incompressible fluid through a pipe, which is driven by an oscillating pressure gradient (. a reciprocating piston), is investigated in the case of a large Reynolds number. This process is described by a singularly perturbed parabolic equation with a periodic...

In this paper, we deal with the real stochastic difference equation = + , ∈ ℤ, where the sequence () is a finite state space Markov chain. By means of the renewal theory, we give a precise description of the situation where the tail of its stationary solution exhibits power law behavior

On construit des contre-examples pour les résultats sur la propagation des singularitées de la solution d'un Systeme semilinéaire et faiblement hyperbolique en une dimension de l'espace, publiés dans J. Math, pures et appl., , 1991, 393–426 et Trans, of the AMS, , 2, 1985, 451–485. Les...
