The Newton Fractal’s Leonardo Sequence Study with the Google Colab [PDF]

International Electronic Journal of Mathematics Education, 2019
The work deals with the study of the roots of the characteristic polynomial derived from the Leonardo sequence, using the Newton fractal to perform a root search. Thus, Google Colab is used as a computational tool to facilitate this process.

Determinant-preserving blind signatures from Hadamard-type t-Jacobsthal–Leonardo sequences [PDF]

Notes on Number Theory and Discrete Mathematics
In this paper, we introduce a new class of sequences called the termed Hadamard-type t-Jacobsthal-Leonardo sequence which is generated by applying a Hadamard-type product to the characteristic polynomials of the t-Jacobsthal and Leonardo sequences.

Non-Fisherian generalized Fibonacci numbers [PDF]

Notes on Number Theory and Discrete Mathematics
Using biology as inspiration, this paper explores a generalization of the Fibonacci sequence that involves gender biased sexual reproduction. The female, male, and total population numbers along with their associated recurrence relations are considered ...

Salvator Mundi: an investigation of the painting’s materials and techniques

Heritage Science, 2020
Before the start of its restoration in 2007, the Salvator Mundi was thought to be one of a number of copies of a long-lost Leonardo da Vinci painting, depicting Christ giving a blessing with his right hand while holding a crystal orb in his left.

Some infinite series summations involving linear recurrence relations of order 2 and 3 [PDF]

Notes on Number Theory and Discrete Mathematics
This paper extends known results of second and third order recursive sequences through extensive formulations of properties of the roots of their characteristic equations, some are old but most are new. They are applied to novel studies of Σₙ₌ₒ^∞ aₘₙ/10ⁿ⁺

The Fibonacci sequence and the nature of mathematical discovery: A semiotic perspective

Sign Systems Studies, 2005
This study looks at the relation between mathematical discovery and semiosis, focusing on the famous Fibonacci sequence. The serendipitous discovery of this sequence as the answer to a puzzle designed by Italian mathematician Leonardo Fibonacci to ...

Rewiews

Techne, 2020
Time and Architecture. The aspects that involve its dichotomous and synchronic relationship (De Fusco, 2019)1, make it a constantly present topic in the architectural debate, intrinsic to any disciplinary aspect.

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Pell Leonardo numbers and their matrix representations

Journal of New Results in Science
In this study, we investigate Pell numbers and Leonardo numbers and describe a new third-order number sequence entitled Pell Leonardo numbers. We then construct some identities, including the Binet formula, generating function, exponential generating ...
