Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Asymptotic behavior of solutions of a partial functional differential equation

open access: yesElectronic Journal of Differential Equations, 2000
The asymptotic behavior of solutions of an asymptotically autonomous partial functional differential equation is investigated. The aim of the present paper is to extend our earlier result for ordinary functional differential equations and difference ...

Reduction of Linear Functional Systems using Fuhrmann's Equivalence

open access: yesSultan Qaboos University Journal for Science, 2016
Functional systems arise in the treatment of systems of partial differential equations, delay-differential equations, multidimensional equations, etc. The problem of reducing a linear functional system to a system containing fewer equations and unknowns ...

Fractional partial differential equations with boundary conditions [PDF]

open access: yes, 2018
We identify the stochastic processes associated with one-sided fractional partial differential equations on a bounded domain with various boundary conditions. This is essential for modelling using spatial fractional derivatives. We show well-posedness of

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

OSCILLATION OF PARTIAL FUNCTIONAL-DIFFERENTIAL EQUATIONS WITH DEVIATING ARGUMENTS

open access: yesTamkang Journal of Mathematics, 1995
A class of partial functional-differential equations with deviating argu- ments including parabolic equations, hyperbolic equations and·beam equations is studied, and sufficient conditions are derived for all solutions of certain boundary value problem to be oscillatory in a cylindrical domain.

Metric Based Upscaling for Partial Differential Equations with a Continuum of Scales [PDF]

open access: yes, 2007
Numerical upscaling of problems with multiple scale structures have attracted increasing attention in recent years. In particular, problems with non-separable scales pose a great challenge to mathematical analysis and simulation.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...
