Some Twitch chats exhibit multifractal characteristics resembling stream-of-consciousness narrative
Marcin Ból, Stanisław Drożdż, Robert Kluszczyński +2
Live-streaming platforms generate high-frequency records of collective human activity in which many loosely coordinated users react in real time to shared external stimuli and to o…
Detrended cross-correlations and their random matrix limit: an example from the cryptocurrency market
Stanisław Drożdż, Paweł Jarosz, Jarosław Kwapień +2
Correlations in complex systems are often obscured by nonstationarity, long-range memory, and heavy-tailed fluctuations, which limit the usefulness of traditional covariance-based…
Filtering amplitude dependence of correlation dynamics in complex systems: application to the cryptocurrency market
Marcin Wątorek, Marija Bezbradica, Martin Crane +2
Based on the cryptocurrency market dynamics, this study presents a general methodology for analyzing evolving correlation structures in complex systems using the -dependent detr…
Multifractality and its sources in the digital currency market
Stanisław Drożdż, Robert Kluszczyński, Jarosław Kwapień +1
Multifractality in time series analysis characterizes the presence of multiple scaling exponents, indicating heterogeneous temporal structures and complex dynamical behaviors beyon…
Temporal correlations versus noise in the correlation matrix formalism: an example of the brain auditory response
J. Kwapien, S. Drozdz, A. A. Ioannides
We adopt the concept of the correlation matrix to study correlations among sequences of time-extended events occuring repeatedly at consecutive time-intervals. As an application we…
Collectivity in the Brain Sensory Response
S. Drozdz, J. Kwapien, A. A. Ioannides +1
A question of cooperative effects in auditory brain processing on various space- and time-scales is addressed. The experimental part of our study is based on Multichannel Magnetoen…
Cooperative dynamics in auditory brain response
J. Kwapien, S. Drozdz, L. C. Liu +1
Simultaneous estimates of the activity in the left and right auditory cortex of five normal human subjects were extracted from Multichannel Magnetoencephalography recordings. Left,…
