Spatial Patterns of Shallow Clouds: Challenging the Concept of Defined Regimes

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Tropical shallow clouds are a major source of uncertainty in Earth's climate sensitivity, especially through their spatial arrangement, which global climate models do not represent. Efforts to understand their organization have partly relied on classifying observed scenes, identifying four patterns as archetypal regimes.

Multifractal properties of a closed contour: a peek beyond the shape analysis.

open access: yesPLoS ONE, 2014
In recent decades multifractal analysis has been successfully applied to characterize the complex temporal and spatial organization of such diverse natural phenomena as heartbeat dynamics, the dendritic shape of neurons, retinal vessels, rock fractures ...

Self‐Affine Scaling of Earth's Islands

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Earth's relief is approximately self‐affine, meaning a zoom‐in on a small region looks statistically similar to a large region upon rescaling. Fractional Brownian surfaces give an idealized self‐affine model of Earth's relief with one parameter, the Hurst exponent H $H$, characterizing the roughness of the surface.

Hölder differentiability of self-conformal devil's staircases

open access: yes, 2014
In this paper we consider the probability distribution function of a Gibbs measure supported on a self-conformal set given by an iterated function system (devil's staircase) applied to a compact subset of ℝ. We use thermodynamic multifractal formalism to

Elucidating the Physical and Mathematical Properties of the Prouhet‐Thue‐Morse Sequence in Quantum Computing

open access: yesAnnalen der Physik, Volume 538, Issue 4, April 2026.
The Prouhet‐Thue‐Morse (PTM) sequence emerges as a unifying thread across quantum error correction, noise‐resistant memories, spin‐chain dynamics, quantum chaos, and Dirichlet links to the Riemann zeta function. Mapping PTM‐encoded logical states onto qubit and qudit architectures uncovers symmetry‐protected resilience and multifractal signatures ...

C. F. v. Weizsächer on Quasistationary Isotropic Turbulence Compared With Onsager's Statistical Hydrodynamics

open access: yesNatural Sciences, Volume 6, Issue 2, April 2026.
v. Weizsäcker and Heisenberg began their turbulence collaboration in 1945 while still quarantined at Farm Hall. Their papers were submitted separately in 1946 from Göttingen. v. Weizsäcker had derived the 5/3 law for dissipation while using dimensional analysis in real space.

Modeling and forecasting time series of precious metals: a new approach to multifractal data

open access: yesFinancial Innovation, 2019
We introduce a novel approach to multifractal data in order to achieve transcended modeling and forecasting performances by extracting time series out of local Hurst exponent calculations at a specified scale.

An Ensemble Multivariate Multiscale Framework for Prediction of Long‐Term Solar Activity With Nonstationary Oscillations

open access: yesEarth and Space Science, Volume 13, Issue 4, April 2026.
Abstract Solar activity is usually characterized by different indices from different perspectives, which are commonly interconnected and contain nonstationary oscillations (NSOs). Given the significant influence of solar activity on space weather, the Earth and humans, it is of great significance to predict solar activity for better understanding not ...
