Cell Mechanics in Cancer: Integrating Mechanotransduction Pathways Within the Tumor Microenvironment

Journal of Cellular Physiology, Volume 241, Issue 5, May 2026.
ABSTRACT Single‐cell mechanical properties such as stiffness, elasticity, and viscosity, are crucial in governing biological processes like migration, proliferation, and differentiation. In cancer, the mechanical properties of cells undergo significant alterations, which contribute to tumor growth, metastasis, and resistance to therapy.

On some properties of k-circulant matrices with the generalized Pell-Padovan numbers

Journal of Innovative Applied Mathematics and Computational Sciences
In this paper, we investigate the properties of the $k$-circulant matrix generated by the generalized Pell--Padovan numbers. We derive explicit formulas for the sum of entries, the maximum column sum norm ($\Vert \cdot \Vert _{1}$), the maximum row sum ...

On the sequences of $(q,k)$-generalized Fibonacci numbers [PDF]

Mathematica Bohemica
We consider a new family of recurrence sequences, the $(q,k)$-generalized Fibonacci numbers. These sequences naturally extend the well-known sequences of $k$-generalized Fibonacci numbers and generalized $k$-order Pell numbers.

Pell numbers

, 2022
Niz Pellovih brojeva zadan je početnim uvjetima \(P_1=1, P_2=2\), te rekurzivnom relacijom \(P_n=2P_{n-1}+P_{n-2}, n \geq 3\). Uz definiciju Pellovih brojeva, u radu su definirani i Pell–Lucasovi brojevi koji su s njima usko povezani.

On q-Pell sequence spaces: A study of operator ideals and geometric properties

Kuwait Journal of Science
The matrix \( \mathcal{P}(q) = \{\Psi_{\lambda \mu}(q)\}_{\lambda, \mu \in \mathbb{N}} \), called the \( q \)-Pell matrix, with elements determined by \[ \mathcal{P}(q) = \begin{cases} \dfrac{2~q^{\mu-1}~\Psi{_\mu(q)}}{\Psi{_{\lambda+1}(q)}+\Psi{_ ...

On a study of (s, t)-generalized pell sequence and its matrix sequence

, 2019
First of all in this article, we consider (s, t)-type sequences such as (s, t)-Pell sequence hPn (s, t)i, (s, t)-Pell-Lucas sequence hQn (s, t)i and (s, t)-Modified Pell sequence hRn (s, t)i.
