Analytical Study of the Julia Set of a Coupled Generalized Logistic Map
, 1998 A coupled system of two generalized logistic maps is studied. In particular influence of the coupling to the behaviour of the Julia set in two dimensional complex space is analyzed both analytically and numerically.

Decrypting cancer's spatial code: from single cells to tissue niches
Molecular Oncology, EarlyView.Spatial transcriptomics maps gene activity across tissues, offering powerful insights into how cancer cells are organised, switch states and interact with their surroundings. This review outlines emerging computational, artificial intelligence (AI) and geospatial approaches to define cell states, uncover tumour niches and integrate spatial data with ...

A refinement of the logistic map for cryptographic applications
Franklin OpenThis paper proposes a one-dimensional chaotic map that is a refinement of the well-known logistic map. The proposed map exhibits chaotic behavior over a much wider domain for its control parameter compared to the logistic map.

Sequential inverse problems Bayesian principles and the\ud logistic map example [PDF]
, 2010 Bayesian statistics provides a general framework for solving inverse problems, but is not without interpretation and implementation problems. This paper discusses difficulties arising from the fact that forward models are always in error to some extent ...

New way to achieve chaotic synchronization in spatially extended systems
, 2000 We study the spatio-temporal behavior of simple coupled map lattices with periodic boundary conditions. The local dynamics is governed by two maps, namely, the sine circle map and the logistic map respectively.
