Global behavior of a higher order nonlinear difference equation
In this paper, we consider a higher order difference equation of the form x n + 1 = f ( x n , x n − k ) , n = 1 , 2 , 3 , … , under some certain assumptions. We obtain that the length of its finite semicycle is less than or equal to k.

Periodicity in a Class of Systems of Delay Difference Equations [PDF]
We study a system of delay difference equations modeling four-dimensional discrete-time delayed neural networks with no internal decay. Such a discrete-time system can be regarded as the discrete analog of a differential equation with piecewise constant ...

Spatiotemporal gravity variations to look deep into the southern flank of Etna volcano
A 14-year-long microgravity data set (October 1994 to September 2007) collected along a 24-km east-west trending profile of 19 stations was analyzed to detect underground mass redistributions related to the volcanic activity involving the southern flank ...
