Scaling turbulence drives the general circulation
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

Wave Transport and Localization in Prime Number Landscapes
In this paper, we study the wave transport and localization properties of novel aperiodic structures that manifest the intrinsic complexity of prime number distributions in imaginary quadratic fields.

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.

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.

Source Of The Multifractality In Exchange Markets: Multifractal Detrended Fluctuations Analysis [PDF]
In this study, we analyzed the multifractality and the source of multifractality of the returns of GBP/USD, EUR/USD, USD/JPY and USD/CHF currencies. In the examination of multifractality we performed the Multifractal Detrended Fluctuation Analysis (MF ...

Modeling Dynamic Multifractal Efficiency of US Electricity Market
The dramatic deregulatory reforms in US electricity markets increased competition, resulting in more complex prices compared to other commodities. This paper aims to investigate and compare the overall and time-varying multifractality and efficiency of ...

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

Multifractal detrended fluctuation analysis of hydroclimatic series across Uganda in East Africa
This study applied Multifractal Detrended Fluctuation Analysis (MFDFA) to investigate the scaling behaviour of streamflow, precipitation, and potential evapotranspiration (PET) in nine Ugandan catchments during 1990–2013.
