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 solutions to a second order partial differential equation with nonlocal conditions
Using the cosine function theory, we prove the existence of mild and classical solutions for an abstract second-order Cauchy problem with nonlocal conditions.

A priori bounds of the solution of a one point IBVP for a singular fractional evolution equation
A priori bounds constitute a crucial and powerful tool in the investigation of initial boundary value problems for linear and nonlinear fractional and integer order differential equations in bounded domains.

Arginine methylation can be viewed as a persistence‐prone post‐translational modification regulated by a network of PRMTs. Competitive and compensatory interactions among PRMTs can redistribute methylation across substrate pools shaped by sequence, structural, spatial, and environmental layers, reinforcing RNA‐processing, chromatin, and signaling ...

Strong solutions for differential equations in abstract spaces
The author considers in a sequentially complete locally convex space \((E,{\mathcal F})\) the initial value problem \[ u_t(t)= f(t, u(t)),\quad u(t_0)= u_0. \] The bounded elements of \(E\) are denoted by \[ E_b:= \Biggl\{x\in E:\| x\|_{{\mathcal F}}= \sup_{\rho\in{\mathcal F}}\,\rho(x)< \infty\Biggr\}.

Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Differential and stochastic equations in abstract Wiener space
AbstractThis paper studies the differential equation (∂∂t) u(t, x) = 12trace A(t, x) D2u(t, x) A∗(t, x) + 〈σ(t, x), Du(t, x)〉 − V(x) u(t, x), u(0, x) = φ(x) in infinite dimensional space. A Kac's type representation of solution in terms of function space integral is proved. Kac's method is modified to work nicely regardless of the dimensionality.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Solution of fractional differential equations via α−ψ $\alpha-\psi$-Geraghty type mappings
Using fixed point results of α−ψ $\alpha-\psi$-Geraghty contractive type mappings, we examine the existence of solutions for some fractional differential equations in b-metric spaces. By some concrete examples we illustrate the obtained results.
