Novel analysis tool for the distance of gold dimers controlled by the DNA strand length on the DNA origami

open access: yesJournal of Microscopy, Volume 297, Issue 2, Page 215-226, February 2025.
Abstract Metallic nanoparticle dimers have been used to enhance the excitation rate of single‐quantum emitters. The interparticle distance (d) of the dimers has a crucial influence on the signal enhancement. Therefore, precise control of d is desired for optimal performance. However, statistical analysis of d has been often restricted to a small number

Fibonacci and Telephone Numbers in Extremal Trees

open access: yesDiscussiones 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.

Connectivity of Markoff mod‐p graphs and maximal divisors

open access: yesProceedings of the London Mathematical Society, Volume 130, Issue 2, February 2025.
Abstract Markoff mod‐p$p$ graphs are conjectured to be connected for all primes p$p$. In this paper, we use results of Chen and Bourgain, Gamburd, and Sarnak to confirm the conjecture for all p>3.45·10392$p > 3.45\cdot 10^{392}$. We also provide a method that quickly verifies connectivity for many primes below this bound.

A note on Fibonacci matrices of even degree

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
This paper presents a construction of m-by-m irreducible Fibonacci matrices for any even m. The proposed technique relies on matrix representations of algebraic number fields which are an extension of the golden section field.

The Safety, Tolerability, and Pharmacokinetics of Active Ingredients From Hydroxysafflor Yellow A in Healthy Chinese Volunteers

open access: yesClinical Pharmacology in Drug Development, Volume 14, Issue 1, Page 79-86, January 2025.
Abstract Hydroxysafflor yellow A (HSYA), an active ingredient extracted from Carthami flos, shows potential for treating ischemic stroke. This phase 1 study assessed the safety, tolerability, and pharmacokinetic (PK) properties of HSYA in healthy Chinese volunteers who received intravenous infusions of pure HSYA powder.

Families of Integral Cographs within a Triangular Array

open access: yesSpecial Matrices, 2020
The determinant Hosoya triangle, is a triangular array where the entries are the determinants of two-by-two Fibonacci matrices. The determinant Hosoya triangle mod 2 gives rise to three infinite families of graphs, that are formed by complete product ...

Fibonacci Numbers, Golden Section and Applications [PDF]

open access: yesarXiv, 2013
In this thesis we examined mathematical properties of Fibonacci numbers and applications of this numbers in the nature,geometry and economy.We obtained Golden section and proved some mathematical identities using Golden section. Infinity of the prime numbers proved by using properties of Fibonacci numbers.

δ-Fibonacci numbers

open access: yesApplicable Analysis and Discrete Mathematics, 2009
The scope of the paper is the definition and discussion of the polynomial generalizations of the Fibonacci numbers called here ?-Fibonacci numbers. Many special identities and interesting relations for these new numbers are presented. Also, different connections between ?-Fibonacci numbers and Fibonacci and Lucas numbers are proven in this paper.
