migraine is a neurologic disease, which often is associated with a unilateral headache. vestibular abnormalities are common in migraine. vestibular evoked myogenic potentials (vemps) assess otolith function in particular functional integrity of the saccule and the inferior vestibular nerve. we used vemp to evaluate if the migraine headache can affect vemp asymmetry parameters. a total of 25 pat...

A generalized inverse problem for a two-dimensional difference operator is introduced. Two operators, for which such a problem is solved (we call such operators algebro-geometric), are found.

The SEIR model for the transmission dynamics of measles is extended by the addition of second-order space derivatives to enable the geographic spread of the disease in a population which has not been vaccinated against it. The resulting system of three reaction-diffusion equations is solved by a convergent finite-difference technique which is second-order accurate in space and time. A parallel ...

In this paper we introduce certain new sequence spaces of fuzzy numbers defined by Iconvergence using sequences of Orlicz functions and a difference operator of orderm. We study some basic topological and algebraic properties of these spaces. Also we investigate the relations related to these spaces. © 2011 Elsevier Ltd. All rights reserved.

Both edge finders use the topological sum to remove noise from second difference responses, so that zero-crossings in these responses represent reliable boundaries. Spectre applies the same techniques to a combination of first and third differences, producing a new map that reliably distinguishes real boundaries from spurious boundaries appearing in staircase intensity patterns. Similar process...
