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.

Numerical approximations of McKean anticipative backward stochastic differential equations arising in initial margin requirements* [PDF]

open access: yesESAIM: Proceedings and Surveys, 2019
We introduce a new class of anticipative backward stochastic differential equations with a dependence of McKean type on the law of the solution, that we name MKABSDE.

Alternative methods for representing the inverse of linear programming basis matrices [PDF]

open access: yes, 1988
Methods for representing the inverse of Linear Programming (LP) basis matrices are closely related to techniques for solving a system of sparse unsymmetric linear equations by direct methods.

Linearly Implicit General Linear Methods [PDF]

open access: yes, 2021
Linearly implicit Runge–Kutta methods provide a fitting balance of implicit treat- ment of stiff systems and computational cost. In this paper we extend the class of linearly implicit Runge–Kutta methods to include multi-stage and multi-step methods.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

A Generalized Model for Fuzzy Linear Programs with Trapezoidal Fuzzy Numbers

open access: yesJournal of Applied Research on Industrial Engineering, 2017
In this paper, we generalize a linear programming problem with symmetric trapezoidal ‎fuzzy number which is introduced by Ganesan and et al. in [3] to a general kind of trapezoidal fuzzy number. In this way, we first establish a new ‏arithmetic operation

Classification of structural MRI images in Alzheimer's disease from the perspective of ill-posed problems. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND:Machine learning neuroimaging researchers have often relied on regularization techniques when classifying MRI images. Although these were originally introduced to deal with "ill-posed" problems it is rare to find studies that evaluate the ill ...

A variance shilf model for outlier detection and estimation in linear and linear mixed models [PDF]

open access: yes, 2008
Includes abstract.Includes bibliographical references.Outliers are data observations that fall outside the usual conditional ranges of the response data.They are common in experimental research data, for example, due to transcription errors or faulty ...
