Almost periodic and quasi-periodic functions. A brief survey and some applications [PDF]

Surveys in Mathematics and its Applications
In the present work, we study almost-periodic and quasi-periodic functions, their main properties and some related results. We also present almost periodic functions with parameters, which we adapt to the quasi-periodic framework. We then show that these

Weighted Pseudo Almost-Periodic Functions and Applications to Semilinear Evolution Equations

Abstract and Applied Analysis, 2012
We first give a solution to a key problem concerning the completeness of the space of weighted pseudo almost-periodic functions and then establish a new composition theorem with respect to these functions.

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Asymptotic Almost Periodic Functions with Range in a Topological Vector Space

Journal of Function Spaces and Applications, 2013
The notion of asymptotic almost periodicity was …first introduced by Fréchet in 1941 in the case of …finite dimensional range spaces. Later, its extension to the case of Banach range spaces and locally convex range spaces has been considered by several ...

Algunos aspectos teóricos de las funciones casi periódicas n-dimensionales

Revista de Matemática: Teoría y Aplicaciones, 2009
We five a definition of Almost Periodic Functions on Ñ N. Following that definition we show some topological properties for this functions. At the end of this paper we proof some algebraic properties by using the structure theorem.

Factorization of Almost Periodic Matrix Functions

Journal of Mathematical Analysis and Applications, 1995
Let \(AP\) be the space of Bohr almost periodic functions \(f(x) \sim \sum_j f_j e^{i \lambda_j x}\). Let \(\widehat f (\lambda) = M(e^{- i \lambda x} f(x))\) and \(\Omega (f) = \{\lambda \in \mathbb{R} : \widehat f (\lambda) \neq 0\}\), \(\mathbb{R}_\pm = \{x \in \mathbb{R} : \pm x \geq 0\}\), \(AP^\pm = \{f \in AP : \Omega (f) \subset\mathbb{R}_\pm\}\

Castration‐resistant prostate cancer cells are addicted to the high activity of cyclin‐dependent kinase 2

Molecular Oncology, EarlyView.
We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...

Generalized Almost Periodicity in Measure

Mathematics
This paper investigates diverse classes of multidimensional Weyl and Doss ρ-almost periodic functions in a general measure setting. This study establishes the fundamental structural properties of these generalized ρ-almost periodic functions, extending ...

Profiling neoadjuvant therapy response in rectal cancer using meta‐analysis of publicly available transcriptomic RNA‐seq datasets

Molecular Oncology, EarlyView.
This study integrates publicly available transcriptomic datasets to identify molecular signatures associated with response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer. By analyzing a combination of multiple cohorts with bioinformatics approaches, we reveal biological pathways and immune‐related features that may improve ...

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

Molecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.
