Lucas Numbers and Cryptography [PDF]

open access: yes, 2012
We know that the Fibonacci numbers are the numbers from Fibonacci sequence. It was discovered by Leonardo de Fibonacci de Pisa. The Fibonacci series was derived from the solution to a problem about rabbits.

Relationship between Vieta-Lucas polynomials and Lucas sequences

open access: yes, 2022
Let $w_n=w_n(P,Q)$ be numerical sequences which satisfy the recursion relation \begin{equation*} w_{n+2}=Pw_{n+1}-Qw_n. \end{equation*} We consider two special cases $(w_0,w_1)=(0,1)$ and $(w_0,w_1)=(2,P)$ and we denote them by $U_n$ and $V_n$ respectively. Vieta-Lucas polynomial $V_n(X,1)$ is the polynomial of degree $n$.

From Sample to Mixed Reality: A Translational 3D MALDI Imaging Platform for Advanced 3D Spatial Omics Analysis of 3D Cell Culture Disease Models

open access: yesAdvanced Science, EarlyView.
A comprehensive technology platform enables high‐fidelity, volumetric MALDI imaging of 3D cell cultures by integrating custom embedding molds, a semi‐automated computational framework for 3D reconstruction, voxel‐instead of pixel‐based biomarker discovery, and immersive mixed reality data exploration.

Horadam–Lucas Cubes

open access: yesAxioms
In this paper, we introduce a novel class of graphs referred to as the Horadam–Lucas cubes. This class extends the concept of Lucas cubes and retains numerous desirable properties associated with them.

On fourth-order jacobsthal quaternions

open access: yesJournal of Mathematical Sciences and Modelling, 2018
In this paper, we present for the first time a sequence of quaternions of order 4 that we will call the fourth-order Jacobsthal and the fourth-order Jacobsthal-Lucas quaternions. In particular, we are interested in the generating function, Binet formula,

Binomial coefficients, Catalan numbers and Lucas quotients

open access: yes, 2010
Let $p$ be an odd prime and let $a,m$ be integers with $a>0$ and $m \not\equiv0\pmod p$. In this paper we determine $\sum_{k=0}^{p^a-1}\binom{2k}{k+d}/m^k$ mod $p^2$ for $d=0,1$; for example, $$\sum_{k=0}^{p^a-1}\frac{\binom{2k}k}{m^k}\equiv\left(\frac{m^

The Square Terms in Lucas Sequences

open access: yesJournal of Number Theory, 1996
Let \(P\) and \(Q\) be relatively prime odd integers and define the sequences \(\{U_n\}\) and \(\{V_n\}\) by \(U_n = PU_{n - 1} - QU_{n - 2}\) with \(U_0 = 0\), \(U_1 = 1\) and \(V_n = PV_{n - 1} - QV_{n - 2}\) with \(V_0 = 2\), \(V_1 = P\). The main results of the paper are the following. (i) If \(V_n\) is a square, then \(n = 1,3\) or 5.

Ruddlesden–Popper Structured Sr3Fe2O7−δ as Redox‐Activated CO2 Sorbents for Green Hydrogen Production

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
A‐site and B‐site doped strontium ferrite‐type Ruddlesden–Popper oxides are evaluated as CO2 sorbents for glycerol‐based hydrogen production via sorption‐enhanced steam reforming. A Sr1.4Ca0.6Fe0.9Ni0.1O4−δ composition forms an active Sr3Fe2O7 phase, achieving ≈95 vol% H2 purity and over sixfold longer CO2 prebreakthrough time (tpb) than its perovskite

Quaternion-Type Catalan Transforms of the ρ-Fibonacci and ρ-Lucas Numbers

open access: yesJournal of Mathematics, 2023
In this paper, we define a new sequence called the quaternion-type Catalan sequence and give generating function, exponential representation, quaternionic Catalan matrix and its some properties.
