On The Recursive Sequence x(n+1)=x(n-20)/[1+x(n-2)x(n-5)x(n-8)x(n-11)x(n-14)x(n-17)]

MANAS: Journal of Engineering, 2019
The behaivour of the solutions of the following system ofdifference equations is examined,x(n+1)=x(n-20)/[1+x(n-2)x(n-5)x(n-8)x(n-11)x(n-14)x(n-17)]where the initial conditions are positive real numbers.The initial conditions of the equation are ...

Surfaceome: a new era in the discovery of immune evasion mechanisms of circulating tumor cells

Molecular Oncology, Volume 19, Issue 7, Page 1979-1997, July 2025.
In the era of immunotherapies, many patients either do not respond or eventually develop resistance. We propose to pave the way for proteomic analysis of surface‐expressed proteins called surfaceome, of circulating tumor cells. This approach seeks to identify immune evasion mechanisms and discover potential therapeutic targets. Circulating tumor cells (

Moduli spaces of d-connections and difference Painleve equations [PDF]

, 2006
We show that difference Painleve equations can be interpreted as isomorphisms of moduli spaces of d-connections on the projective line with given singularity structure. We also derive a new difference equation.

The Form of the Solutions of System of Rational Difference Equation

Journal of Mathematical Sciences and Modelling, 2018
In this article, we study the form of the solutions of the system of difference equations $x_{n+1}=((y_{n-8})/(1+y_{n-2}x_{n-5}y_{n-8}))$, $y_{n+1}=((x_{n-8})/(\pm1\pm x_{n-2}y_{n-5}x_{n-8}))$, with the initial conditions are real numbers.

Stability analysis for a rational difference equation

Arab Journal of Basic and Applied Sciences, 2020
Most qualitative behaviours of difference equations are rapidly investigated nowadays. This can be attributed to the fact that it is often sophisticated to construct the exact solutions of most difference equations. This article is written to analyse the

Circulating tumor cells in metastatic breast cancer patients treated with immune checkpoint inhibitors – a biomarker analysis of the ALICE and ICON trials

Molecular Oncology, Volume 19, Issue 7, Page 2092-2108, July 2025.
In this explorative biomarker analysis, we assessed serial sampling of circulating tumor cells (CTCs) with CellSearch in two randomized trials testing immune checkpoint inhibitors (ICIs) in metastatic breast cancer. Our data demonstrate a prognostic potential of CTCs, most apparent 4 weeks into ICI therapy.

Teaching the Logistic Growth Difference Equation Using Spreadsheets

Spreadsheets in Education, 2010
The logistic growth difference equation is often used in biology to model population growth. The terms that satisfy the difference equation have many remarkable mathematical properties such as exhibiting chaotic behavior. Using spreadsheet modeling tools,

Dynamics of a system of rational third-order difference equation

, 2012
In this paper, we study the dynamical behavior of positive solution for a system of a rational third-order difference equation xn+1=xn−2B+yn−2yn−1yn,yn+1=yn−2A+xn−2xn−1xn,n=0,1,…, where A,B∈(0,∞), x−2,x−1,x0∈(0,∞); y−2,y−1,y0∈(0,∞).MSC:39A10.

A comparative study of circulating tumor cell isolation and enumeration technologies in lung cancer

Molecular Oncology, Volume 19, Issue 7, Page 2014-2037, July 2025.
Lung cancer cells were spiked into donor blood to evaluate the recovery rates of the following circulating tumor cell (CTC) enrichment technologies: CellMag™, EasySep™, RosetteSep™, Parsortix® PR1, and Parsortix® Prototype systems. Each method's advantages and disadvantages are described.

A reduction technique for Generalised Riccati Difference Equations [PDF]

, 2013
This paper proposes a reduction technique for the generalised Riccati difference equation arising in optimal control and optimal filtering. This technique relies on a study on the generalised discrete algebraic Riccati equation.
