Impact Plasma Amplification of the Ancient Mercury Magnetic Field

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Spacecraft measurements of Mercury indicate that it has a core dynamo with a surface field of 200–800 nT. These data also indicate that the northern hemisphere crust contains remanent magnetization likely produced by an ancient magnetic field. The inferred magnetization intensity is consistent with a wide range of paleofield strengths (0.2–50 ...

Interior Models of Mercury and Conditions for Iron Snow Formation in a Fe‐S‐Si Core

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Mercury's unique interior structure and magnetic field generation remain to be fully understood. We construct models to further constrain Mercury's interior and test the hypothesis that iron snow within the liquid core drives the dynamo.

Contrasting patterns of population structure in two habitat‐forming kelp species in southeastern Australia

Journal of Phycology, Volume 62, Issue 2, Page 412-426, April 2026.
Abstract The distribution and connectivity of species around the globe are changing at a rapid pace. Increasing sea temperatures are a driving factor of changes in temperate macroalgal distributions. Southeast Australia is considered a global ocean‐warming hotspot, where macroalgal populations are predicted to decline significantly by 2100.

The Venetian Vernacular Lexicon in Eleventh‐ and Twelfth‐Century Latin Documents: Insights from the Codice Diplomatico Veneziano

Transactions of the Philological Society, Volume 124, Issue 1, Page 168-199, March 2026.
Abstract This study investigates the lexicographical potential of Medieval Latin documentation from the Venetian area of the Italo‐Romance domain, highlighting the need for a systematic approach to bridge Latin and vernacular linguistic developments. The project MEDITA – Medieval Latin Documentation and Digital Italo‐Romance Lexicography.

Padovan and Perrin hyperbolic spinors [PDF]

In this study, we intend to bring together Padovan and Perrin number sequences, which are one of the most popular third-order recurrence sequences, and hyperbolic spinors, which are used in several disciplines from physics to mathematics, with the help ...

Dual Proximal Groups Concisely Representing Complex Hosoya Triangles

Advances in Mathematical Physics, Volume 2026, Issue 1, 2026.
This paper introduces dual proximal groups (DPGs) that provide concise representation of complex Hosoya triangles (CHTs). An application is given in terms of the DPG representation of collections of Hosoya‐Hilbert circular triangles on modulated motion waveforms in sequences of video frames. MSC2020 Classification: 11B39,54E05,57S25.

Generalized Padovan Numbers

Symmetry
In this paper, we study a generalization of Padovan numbers. We define a generating function and matrix generators for the generalized Padovan sequence. Moreover, using graph methods and a special family of generalized Padovan sequences, we derive a multinomial formula for generalized Padovan numbers. We also prove some identities that generalize known

Common terms of k-Pell numbers and Padovan or Perrin numbers

Arabian Journal of Mathematics, 2022
AbstractLet $$k\ge 2$$ k ≥ 2 . A generalization of the well-known Pell sequence is the k-Pell sequence. For this sequence, the first k terms are $$0,\ldots ,0,1$$ 0 ,

Counting Maximal Distance-Independent Sets in Grid Graphs

Discussiones Mathematicae Graph Theory, 2013
Previous work on counting maximal independent sets for paths and certain 2-dimensional grids is extended in two directions: 3-dimensional grid graphs are included and, for some/any ℓ ∈ N, maximal distance-ℓ independent (or simply: maximal ℓ-independent ...

Polar Motion Dynamics on Slow‐Rotating Venus: Signatures of Mantle Flow

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract With its 1 day lasting 243 days on Earth, Venus is the slowest‐spinning planet in the Solar System and its rotational bulge is anomalously small. A rotational bulge stabilizes the orientation of planets. Having only a tiny stabilizer, the rotational pole of Venus has been expected to separate from the figure pole in response to mantle flow ...
