Donor‐acceptor fractal synergy: Decoding self‐similarity for stable organic photovoltaics
FlexMat, EarlyView.Morphological congruence between donor and acceptor refines the fractal structure of bulk heterojunction films and enhances their self‐similarity. This optimized multiscale morphology preserves charge‐transport pathways against external disturbances, suppresses structural degradation, and improves the operational stability of organic solar cells while ...

Multifractal Analysis of Hydrologic Data Using Wavelet Methods and Fluctuation Analysis
Discrete Dynamics in Nature and Society, 2017 We study the multifractal properties of water level with a high-frequency and massive time series using wavelet methods (estimation of Hurst exponents, multiscale diagram, and wavelet leaders for multifractal analysis (WLMF)) and multifractal detrended ...

Multifractal analysis of malaria cases in India in a global warming scenario
Journal of Water and Climate Change, 2023 An effort is made to evaluate the multifractal properties of malaria cases in India from 1980 to 2014. The possible changes in these properties in a global warming scenario (during 2015–2049) are also quantified.

International Journal of Finance &Economics, EarlyView.ABSTRACT This study examines risk transmission and co‐movements between financial markets (G7 countries and China) and commodity markets (gold and oil) during the COVID‐19 crisis. Daily closing prices for major equity indices (CAC40, CSI300, DAX30, FTSE100, MIB, NIKKEI, TSX and S&P500) and futures prices for gold, brent and WTI were analysed using DCC ...

Directed graph iterated function systems [PDF]
, 2011 This thesis concerns an active research area within fractal geometry. In the first part, in Chapters 2 and 3, for directed graph iterated function systems (IFSs) defined on ℝ, we prove that a class of 2-vertex directed graph IFSs have attractors that ...

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 ...
