From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Existence of doubly-weighted pseudo almost periodic solutions to non-autonomous differential equations

open access: yesElectronic Journal of Differential Equations, 2011
First we show that if the doubly-weighted Bohr spectrum of an almost periodic function exists, then it is either empty or coincides with the Bohr spectrum of that function.

Almost periodic functions [PDF]

open access: yes, 2019
Diplomska naloga opisuje skoraj periodične funkcije in njihove Fourierove vrste. Skoraj periodična funkcija je vsaka funkcija, ki jo lahko na $mathbb{R}$ poljubno natančno enakomerno aproksimirano s končno linearno kombinacijo kosinusov ter sinusov ...

The ubiquitin system in normal and infected germinal center B cells

open access: yesFEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Global convergence dynamics of almost periodic delay Nicholson's blowflies systems

open access: yesJournal of Biological Dynamics, 2020
We take into account nonlinear density-dependent mortality term and patch structure to deal with the global convergence dynamics of almost periodic delay Nicholson's blowflies system in this paper.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Almost Periodic Functionals on Banach Algebras

open access: yesRocky Mountain Journal of Mathematics, 1992
This paper discusses the almost periodic functionals \(ap(A)\) and the weakly almost periodic functionals \(wap(A)\) on a Banach algebra \(A\). A pleasing and surprising result is an early key lemma: if the set \(\Phi_ A\) of multiplicative functionals separates the points of \(A\), and if \(a\in A\) is such that left translation by \(a\) is weakly ...

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

open access: yesMolecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Offset Linear Canonical Stockwell Transform for Boehmians

open access: yesMathematics
In this article, we construct a Boehmian space using the convolution theorem that contains the offset linear canonical Stockwell transforms (OLCST) of all square-integrable Boehmians.
