Emergent multiscale dynamics in photonic neurons with dual feedback [PDF]

open access: yesScientific Reports
Complex dynamical systems are inherently governed by multiscale dynamics, where processes on different temporal, spatial, and intensity scales interact through feedback mechanisms.

Dynamic expression of brain functional systems disclosed by fine-scale analysis of edge time series [PDF]

open access: yesNetwork Neuroscience, 2021
Abstract Functional connectivity (FC) describes the statistical dependence between neuronal populations or brain regions in resting-state fMRI studies and is commonly estimated as the Pearson correlation of time courses. Clustering or community detection reveals densely coupled sets of regions constituting resting-state networks or ...

Hierarchical time‐series analysis of dynamic bioprocess systems

open access: yesBiotechnology Journal, 2022
AbstractBackgroundMonoclonal antibodies (mAbs) are leading types of ‘blockbuster’ biotherapeutics worldwide; they have been successfully used to treat various cancers and chronic inflammatory and autoimmune diseases. Biotherapeutics process development and manufacturing are complicated due to lack of understanding the factors that impact cell ...

Reservoir time series analysis: Using the response of complex dynamical systems as a universal indicator of change [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2022
We present the idea of reservoir time series analysis (RTSA), a method by which the state space representation generated by a reservoir computing (RC) model can be used for time series analysis. We discuss the motivation for this with reference to the characteristics of RC and present three ad hoc methods for generating representative features from the

Nonlinear Analysis of Return Time Series Model by Oriented Percolation Dynamic System [PDF]

open access: yesAbstract and Applied Analysis, 2013
Fluctuation dynamics of financial price changes is developed and investigated by oriented percolation system; oriented percolation is percolation with a special direction along which the activity can only propagate one way but not the other. Then, nonlinear behaviors of distribution and leverage effect of return time series are studied for the proposed
