Synthetic Geology: Structural Geology Meets Deep Learning
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.Abstract Reconstructing the structural geology and mineral composition of the first few kilometers of the Earth's subsurface from sparse or indirect surface observations remains a long‐standing challenge with critical applications in mineral exploration, geohazard assessment, and geotechnical engineering.

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

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 2, Page 400-412, February 2026.ABSTRACT Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia encountered in clinical practice. Its incidence increases significantly with age and has become a major global public health issue. Although research into the mechanisms of AF has spanned over a century‐ranging from the reentry theory to the rotor hypothesis‐none of these

Recoletos Multidisciplinary Research Journal, 2013 It is important to realize at the beginning of a statistical analysis whether the data are from a monofractal or multifractal distribution because the methods of analysis are different for each. In seismic sequence analysis, for instance, the monofractal

Wavelet Leaders Based Vibration Signals Multifractal Features of Plunger Pump in Truck Crane
Advances in Mechanical Engineering, 2013 Vibration signal of plunger pump in truck crane is a typical nonlinear, nonstationary signal, and the multifractal features are a powerful tool for depicting the geometry features of such signals.

Transience and multifractal analysis
Annales de l'Institut Henri Poincaré C, Analyse non linéaire, 2017 We study dimension theory for dissipative dynamical systems, proving a conditional variational principle for the quotients of Birkhoff averages restricted to the recurrent part of the system. On the other hand, we show that when the whole system is considered (and not just its recurrent part) the conditional variational principle does not necessarily ...
