Julia and Mandelbrot Sets for Dynamics over the Hyperbolic Numbers

open access: yesFractal and Fractional, 2019
Julia and Mandelbrot sets, which characterize bounded orbits in dynamical systems over the complex numbers, are classic examples of fractal sets. We investigate the analogs of these sets for dynamical systems over the hyperbolic numbers.

On Benford’s Law and the Coefficients of the Riemann Mapping Function for the Exterior of the Mandelbrot Set

open access: yesFractal and Fractional, 2022
We investigate Benford’s law in relation to fractal geometry. Basic fractals, such as the Cantor set and Sierpinski triangle are obtained as the limit of iterative sets, and the unique measures of their components follow a geometric distribution, which ...

Temporal Scaling of Hydrological Signals Reveals Forcing Persistence and Watershed Filtering Across the Contiguous U.S.

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Streamflow temporal persistence reflects both hydrological inputs and watershed filtering, but their relative contributions remain difficult to distinguish. We analyzed spectral scaling in precipitation, evapotranspiration, effective precipitation, streamflow, and the effective precipitation‐to‐streamflow transfer function across 671 ...

Fractal Dimension of Shallow Cumulus Cloud Boundaries Beyond Bulk Fractal Scaling

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Cloud boundaries reflect turbulent mixing and cloud–environment interactions, but their geometric complexity remains poorly quantified. Here, we investigate the complexity of shallow cumulus cloud edge using two fractal approaches: the bulk area–perimeter method and the individual‐cloud box‐counting method.

Assessing Habitat Suitability and Exposure of the Endemic Vasconcellea candicans Under Climate Change and Urban Growth in Lima, Peru

open access: yesEcology and Evolution, Volume 16, Issue 10, October 2026.
This study integrated ensemble species distribution modelling and urban growth projections to evaluate current and future habitat suitability of V. candicans in the lomas ecosystems surrounding Lima under climate change and urban expansion scenarios. Results identified 2891 km2 of current high‐suitability habitat, with strong scenario‐dependent future ...

Fractals: An Eclectic Survey, Part-I

open access: yesFractal and Fractional, 2022
Fractals are geometric shapes and patterns that may repeat their geometry at smaller or larger scales. It is well established that fractals can describe shapes and surfaces that cannot be represented by the classical Euclidean geometry.

Heat Transfer Enhancement in the Microscale: Optimization of Fluid Flow

open access: yesEngineering Reports, Volume 8, Issue 10, October 2026.
Microscale heat transfer deviates from conventional behavior due to scale effects and fluid properties. This review examines single‐phase convection and advanced working fluids, highlighting key mechanisms such as rarefaction, surface effects, and phase interactions, to guide optimized design of high‐performance microchannel heat exchangers.

Deterministic Fractal Plasmonic Metasurfaces for Broadband Mid‐Infrared Molecular Biosensing

open access: yesAdvanced Photonics Research, Volume 7, Issue 9, September 2026.
This image illustrates a sensing platform based on deterministic fractal plasmonic metasurfaces, designed to overcome the persistent trade‐off between sensitivity and spectral bandwidth in surface‐enhanced infrared absorption (SEIRA) spectroscopy. At the heart of the schematic is a hierarchical subwavelength gold aperture array featuring self‐similar ...

The Seepage Characteristics of Single Rough Joint of Granite Based on NMR Technology: A Modified Cubic Law

open access: yesEnergy Science &Engineering, Volume 14, Issue 9, Page 4261-4281, September 2026.
The low‐field nuclear magnetic resonance (NMR) measurements are applied to investigate the seepage characteristics of the single rough joint. The purpose of this paper is to investigate the seepage characteristics of granite specimens with single‐joint channel under the different roughness, confining pressures and seepage pressures.
