On the Stability Domain of a Class of Linear Systems of Fractional Order

open access: yesFractal and Fractional, 2022
In this paper, the shape of the stability domain Sq for a class of difference systems defined by the Caputo forward difference operator Δq of order q∈(0,1) is numerically analyzed.

What Was Homer Honing in the Odyssey?

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract We summarize the data provided in Homer's the Odyssey concerning Odysseus' journey and suggest a completely new view of what was Homer trying to convey to us. We suggest that Homer was honing the idea of synergy between rules (determinism) and chance (randomness), an idea deeply rooted in natural processes as well in mathematics.

Emergence From the Complex Interactions of Epidemics, Droughts, and Floods: Insights From Ming and Qing Dynasties of China During 1470–1911

open access: yesGeoHealth, Volume 9, Issue 12, December 2025.
Abstract With the many health implications of droughts and floods known, and the many adverse secondary and tertiary effects of the Covid‐19 pandemic still lingering, it is important to study the complex interactions of epidemics, droughts, and floods.

Mining Actinomycetes' Metabolomes and Genomes for Anti‐Phytophthora infestans Compounds

open access: yesMicrobial Biotechnology, Volume 18, Issue 12, December 2025.
Using a comparative metabolomic and genomic approach on 63 actinomycetes, this study identified 75 compounds associated with the strains' ability to inhibit the late blight‐causing agent Phytophthora infestans. This study highlighted the promise of applying multi‐omics techniques on closely related strains differing in biological activity to pinpoint ...

The simplicity of physical laws

open access: yesNoûs, Volume 59, Issue 4, Page 957-987, December 2025.
Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

Calculation of the Structure of a Shrub in the Mandelbrot Set

open access: yesDiscrete Dynamics in Nature and Society, 2011
We calculate the external arguments of the structure of any shrub in the Mandelbrot set. Before calculating, we revise, expand, and clarify some tools useful for this paper: harmonics, pseudoharmonics, the concept of structure, the structure of a shrub ...

Pore Structure Characterization and Permeability Evaluation of Deep Tight Dolomite Reservoirs Based on High‐Pressure Mercury Intrusion

open access: yesEnergy Science &Engineering, Volume 13, Issue 11, Page 5373-5384, November 2025.
This figure illustrates the multisegment fractal characteristics of the pores in the deep dolomite sample. ABSTRACT Deep dolomite reservoirs are predominantly tight reservoirs characterized by strong heterogeneity, which is primarily induced by various diagenetic processes such as dissolution, compaction, and cementation.

Fractal Generation via CR Iteration Scheme With S-Convexity

open access: yesIEEE Access, 2019
The visual beauty, self-similarity, and complexity of Mandelbrot sets and Julia sets have made an attractive field of research. One can find many generalizations of these sets in the literature.

A Numerical Study on the Role of Wear During Seismic Cycles of Rough Faults

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract Fault zones mature through the accumulation of slip from multiple earthquakes and the wearing of contact asperities at multiple scales. This study examines how wear affects the evolution of fault seismicity, focusing on earthquake nucleation, recurrence, and moment partitioning.
