A General Approach to Predict and Tailor the Nanoscale Permeability of Comb‐Shaped Polymer Coatings
Small Methods, Volume 9, Issue 7, July 19, 2025.Comb‐shaped polymers are used to produce ‘molecular sieving’ coatings. The steric and size‐selective permeability characteristics of comb‐polymer coatings are systematically explored in silico across a very broad parameter space. All features of the data can be understood when three distinct regimes are considered: i) no‐interactions, ii) weak ...

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.

On the bounds for the spectral norms of geometric circulant matrices
Journal of Inequalities and Applications, 2016 In this paper, we define a geometric circulant matrix whose entries are the generalized Fibonacci numbers and hyperharmonic Fibonacci numbers. Then we give upper and lower bounds for the spectral norms of these matrices.

Colored Partitions and the Fibonacci Sequence
Trends in Computational and Applied Mathematics, 2006 We present interesting combinatorial interpretations for the Fibonacci numbers in terms of colored partitions obtained by using finite versions of two identities of the Rogers-Ramanujan type. New formula for the Fibonacci numbers is also given.

Adaptive Fractional Hybrid Impedance Control of Rotary Series Elastic Actuator in Flat Terrains
Advanced Intelligent Systems, Volume 7, Issue 6, June 2025.This article presents an adaptive fractional hybrid impedance control (AFH‐IC) approach for rotary series elastic actuators operating on flat terrains. The proposed method integrates fractional‐order control, adaptive fuzzy logic, and particle swarm optimization to enhance torque tracking accuracy and robustness.

Series associated with harmonic numbers, Fibonacci numbers and central binomial coefficients $binom{2n}{n}$ [PDF]
Notes on Number Theory and Discrete MathematicsWe find various series that involve the central binomial coefficients $binom{2n}{n}$, harmonic numbers and Fibonacci numbers. Contrary to the traditional hypergeometric function _pF_q approach, our method utilizes a straightforward transformation to ...
