Viscous compressible flow about blunt bodies using a numerically generated orthogonal coordinate system [PDF]
A numerical solution to the Navier-Stokes equations was obtained for blunt axisymmetric entry bodies of arbitrary shape in supersonic flow. These equations are solved on a finite difference mesh obtained from a simple numerical technique which generates ...

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma
Molecular Oncology, EarlyView.Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.

Nonlinear grid error effects on numerical solution of partial differential equations [PDF]
Finite difference solutions of nonlinear partial differential equations require discretizations and consequently grid errors are generated. These errors strongly affect stability and convergence properties of difference models.

Stability theorems of stochastic difference equations
Journal of Mathematical Analysis and Applications, 1990 Let \(\{A_ n\); \(n\geq 0\}\) be an independent sequence of \(d\times d\) real-valued matrices and f(n,x) be an \({\mathbb{R}}^ d\) valued mapping defined on \({\mathbb{N}}\times {\mathbb{R}}^ d\). The author investigates various definitions of the stability of the solutions of the equation \[ x_{n+1}=A_ nx_ n+f(n,x_ n),\quad x_ 0\in {\mathbb{R}}^ d. \]

RIPK4 function interferes with melanoma cell adhesion and metastasis
Molecular Oncology, EarlyView.RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Solutions of a System of Two Higher-Order Difference Equations in Terms of Lucas Sequence
Universal Journal of Mathematics and Applications, 2019 In this paper we give some theoretical explanations related to the representation for the general solution of the system of the higher-order rational difference equations $$ x_{n+1} = \frac{5 y_{n-k}-5}{y_{n-k}}, \qquad y_{n+1} = \frac{5 x_{n-k}-5}{x_{

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells
Molecular Oncology, EarlyView.This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.
