Spectral properties of two coupled Fibonacci chains
New Journal of Physics, 2023 The Fibonacci chain, i.e. a tight-binding model where couplings and/or on-site potentials can take only two different values distributed according to the Fibonacci word, is a classical example of a one-dimensional quasicrystal.

Spherical GTM: A New Proposition for Visualization of Chemical Data
Molecular Informatics, Volume 44, Issue 5-6, June 2025.The Spherical Generative Topographic Mapping method extends the Generative Topographic Mapping method to a spherical manifold to address known nonflat topology issues. The mathematical formalism of this new approach is described, and its ability to visualize in 2D electron density patterns and a tangible chemical library is showcased.

ISNet: Decomposed Dynamic Spatio‐Temporal Neural Network for Ionospheric Scintillation Forecasts
Space Weather, Volume 23, Issue 6, June 2025.Abstract Accurate prediction of ionospheric scintillation is essential for ensuring the reliability of spaceborne and ground‐based radio wave technology infrastructures, including but not limited to navigation and communication systems. In this study, we propose a deep learning‐based Ionospheric Scintillation Network (ISNet), which can predict the ...

A short note on Layman permutations
Acta Universitatis Sapientiae: Mathematica, 2022 A permutation p of [k] = {1, 2, 3, …, k} is called Layman permutation iff i + p(i) is a Fibonacci number for 1 ≤ i ≤ k. This concept is introduced by Layman in the A097082 entry of the Encyclopedia of Integers Sequences, that is the number of Layman ...

Journal of Applied Crystallography, Volume 58, Issue 3, Page 1034-1049, June 2025.Predicted protein structures containing flexible regions, or solved structural units linked by disordered segments, will not have a unique conformation in solution. Starting from a single structure, the SAXS‐A‐FOLD webserver can generate thousands of conformations using a Monte Carlo method.

Another type of generalized fibonacci series
Semina: Ciências Exatas e Tecnológicas, 2004 The Fibonacci sequence, with many applications and occurrences in nature and arts is discussed in the present work. It is considered a generalization of the Fibonacci series by the introduction of a real coefficient in the recurrence relation.

Fibonacci and Telephone Numbers in Extremal Trees
Discussiones Mathematicae Graph Theory, 2018 In this paper we shall show applications of the Fibonacci numbers in edge-coloured trees. In particular we determine the successive extremal graphs in the class of trees with respect to the number of (A, 2B)-edge colourings.

Viewpoint Optimization for 3D Graph Drawings
Computer Graphics Forum, Volume 44, Issue 3, June 2025.Abstract Graph drawings using a node‐link metaphor and straight edges are widely used to represent and understand relational data. While such drawings are typically created in 2D, 3D representations have also gained popularity. When exploring 3D drawings, finding viewpoints that help understanding the graph's structure is crucial.
