FIRST-ORDER SYSTEM LEAST-SQUARES FOR DARCY-STOKES FLOW

open access: yes, 2008
. The subject of this paper is a first-order system least-squares formulation for the Stokes equation which remains uniformly valid in the limit of vanishing viscosity.

Explicit solutions for a system of first-order partial differential equations

open access: yesElectronic Journal of Differential Equations, 2008
In this paper we construct explicit weak solutions of a system of two partial differential equations in the quarter plane ${(x,t):x>0,t>0}$ with initial conditions at $t=0$ and a weak form of Dirichlet boundary conditions at $x=0$. This system was

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

optimal convergence rates for a first order system least squares method. Part I: homogeneous boundary conditions

open access: yes, 2020
We analyze a divergence based first order system least squares method applied to a second order elliptic model problem with homogeneous boundary conditions. We prove optimal convergence in the $L^2(\Omega)$ norm for the scalar variable. Numerical results

Patient facing decision support system for interpretation of laboratory test results

open access: yesBMC Medical Informatics and Decision Making, 2018
Background In some healthcare systems, it is common that patients address laboratory test centers directly without a physician’s recommendation. This practice is widely spread in Russia with about 28% of patients who visiting laboratory test centers for ...

Mixed‐class J‐domain protein scaffolds promote expanded aggregate handling and multivalent Hsp70 engagement during functional disaggregase assembly

open access: yesFEBS Letters, EarlyView.
Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...

Optimal convergence rates in L² for a first order system least squares finite element method -- Part II: inhomogeneous Robin boundary conditions [PDF]

open access: yes
We consider divergence-based high order discretizations of an L²-based first order system least squares formulation of a second order elliptic equation with Robin boundary conditions.

Error estimates for asymptotic solutions of dynamic equations on time scales

open access: yesElectronic Journal of Differential Equations, 2007
We establish error estimates for first-order linear systems of equations and linear second-order dynamic equations on time scales by using calculus on a time scales [1,4,5] and Birkhoff-Levinson's method of asymptotic solutions [3,6,8,9].
