As the Covid-19 pandemic has shown, we live in a richly connected world, facilitating not only the efficient spread of a virus but also of information and influence. What can we learn by analyzing the...
Impurity and quaternions in nonrelativistic scattering from a quantum memory
Impurity and quaternions nonrelativistic scattering quantum memory

2015/10/16
Models of quantum computing rely on transformations of the states of a quantum memory. We study mathematical aspects of a model proposed by Wu in which the memory state is changed via the scattering o...
Fading memory and the problem of approximating nonlinear operators with Volterra series

2015/8/13
Using the notion of fading memory, very strong versions of two theorems are proved. The first is that any time-invariant (TI) continuous nonlinear operator can be approximated by a Volterra series ope...

Abstract: We study how quantization, occurring when a continuously varying process is approximated by or observed on a grid of discrete values, changes the properties of a Gaussian long-memory process...
Marginal density estimation for linear processes with seasonal long memory

2011/2/25
Some convergence results on the kernel density estimator are proven for a class of linear processes with seasonal effects.
Flash memory is well-known for its inherent asymmetry:the flash-cell charge levels are easy to increase but are hard to decrease.

In this paper, we study robust estimators of the memory parameter d of a (possibly) non stationary Gaussian time series with generalized spectral density f. This generalized spectral density is chara...
Self-organized criticality as a precursor of fatigue: application to shape memory alloys
