A New Fractional Discrete Memristive Map with Variable Order and Hidden Dynamics
Fractal and FractionalThis paper introduces and explores the dynamics of a novel three-dimensional (3D) fractional map with hidden dynamics. The map is constructed through the integration of a discrete sinusoidal memristive into a discrete Duffing map.

S-box design method based on improved one-dimensional discrete chaotic map
Journal of Information and Telecommunication, 2018 A new method for obtaining random bijective S-boxes based on improved one-dimensional discrete chaotic map is presented. The proposed method uses a new special case of discrete chaotic map based on the composition of permutations, in order to overcome ...

Place cell rate remapping by CA3 recurrent collaterals. [PDF]
PLoS Computational Biology, 2014 Episodic-like memory is thought to be supported by attractor dynamics in the hippocampus. A possible neural substrate for this memory mechanism is rate remapping, in which the spatial map of place cells encodes contextual information through firing rate ...

From fractional differential equations with Hilfer derivatives
Computational and Applied Mathematics, 2021 In this article, we proposed new discrete maps with memory (DMM). These maps are derived from fractional differential equations (FDE) with the Hilfer fractional derivatives of non-integer orders and periodic sequence of kicks. The suggested DMM are obtained from these equations without any approximation, and they are a discrete form of the exact ...

Inducible and targeted deletion of the ERK5 MAP kinase in adult neurogenic regions impairs adult neurogenesis in the olfactory bulb and several forms of olfactory behavior. [PDF]
PLoS ONE, 2012 Although adult-born neurons in the subventricular zone (SVZ) and olfactory bulb (OB) have been extensively characterized at the cellular level, their functional impact on olfactory behavior is still highly controversial with many conflicting results ...

Dynamics of Sequence-Associative Memory for Discrete Maps in XY Spin Systems [PDF]
Progress of Theoretical Physics, 2002 Summary: A phase coupled oscillator neural network with amplitude modification and a phase shift is studied as a model of sequence-associative memory. The dynamical properties of the pattern recalling process are very important. With regard to the equilibrium state of the system, there have been many studies based on the replica method.

Discrete map with memory from fractional differential equation of arbitrary positive order [PDF]
Journal of Mathematical Physics, 2009 Derivatives of fractional order with respect to time describe long-term memory effects. Using nonlinear differential equation with Caputo fractional derivative of arbitrary order α>0, we obtain discrete maps with power-law memory. These maps are generalizations of well-known universal map.
