Acute and Chronic Local Field Potential Recordings in Dystonia—A Systematic Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Dystonia is a hyperkinetic movement disorder increasingly conceptualized as a disorder of distributed network dysfunction involving the basal ganglia, cortex and cerebellum. Local field potentials (LFPs) recorded from deep brain stimulation (DBS) electrodes provide a unique opportunity to characterize the electrophysiological signatures ...

Multiscale Adaptive Multifractal Detrended Fluctuation Analysis-Based Source Identification of Synchrophasor Data [PDF]

, 2022
As a typical cyber-physical system, dispersed Phasor Measurement Units (PMUs) are networked together with advanced communication infrastructures to record the Distribution Synchrophasor (DS) which represents the states and dynamics of distribution power ...

Scaling turbulence drives the general circulation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

Cross-Correlation Multifractal Analysis of Technological Innovation, Financial Market and Real Economy Indices

, 2023
Technological innovation, the financial market, and the real economy are mutually promoting and restricting. Considering the interference of market-noise information, this paper applies the wavelet-denoising method of the soft- and hard-threshold ...

Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

Mathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 14964-15009, 15 September 2026.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

Tool Embodiment Is Reflected in Movement Multifractal Nonlinearity

Fractal and Fractional, 2022
Recent advances in neuroscience have linked dynamical systems theory to cognition. The main contention is that extended cognition relies on a unitary brain-body-tool system showing the expected signatures of interaction-dominance reflected in a ...

Multifractal Analysis of Inhomogeneous Bernoulli Products [PDF]

Journal of Statistical Physics, 2011
We are interested to the multifractal analysis of inhomogeneous Bernoulli products which are also known as coin tossing measures. We give conditions ensuring the validity of the multifractal formalism for such measures. On another hand, we show that these measures can have a dense set of phase transitions.

Long‐Range Dependence, Multifractality, and Trends of Drought Across Multiple Accumulation Periods in Türkiye Derived From SPEI

Atmospheric Science Letters, Volume 27, Issue 9, September 2026.
The persistence and complexity analyses suggested a gradual change in drought dynamics with increasing time scales. The DFA scaling exponent (α) increased from 0.49 to 1.23, indicating a tendency toward greater temporal persistence at longer accumulation periods.

Forecasting Volatility of Commodity, Currency, and Stock Markets: Evidence From Markov‐Switching Multifractal Models

Journal of Forecasting, Volume 45, Issue 6, Page 2905-2941, September 2026.
ABSTRACT This paper adopts a bivariate Markov‐switching multifractal (BMSM) model to reexamine comovement in SV between commodity, foreign exchange (FX), and stock markets. After the 2007–2008 global financial crisis understanding volatility linkages and the correlation structure between these markets becomes very important for risk analysts, portfolio
