Structural and practical identifiability analysis of partially observed dynamical models by exploiting the profile likelihood

…, M Schilling, U Klingmüller, J Timmer - …, 2009 - academic.oup.com
Motivation: Mathematical description of biological reaction networks by differential equations
leads to large models whose parameters are calibrated in order to optimally explain …

[HTML][HTML] Lessons learned from quantitative dynamical modeling in systems biology

…, BD Harms, FJ Theis, U Klingmüller, J Timmer - PloS one, 2013 - journals.plos.org
Due to the high complexity of biological data it is difficult to disentangle cellular processes
relying only on intuitive interpretation of measurements. A Systems Biology approach that …

Data-based identifiability analysis of non-linear dynamical models

S Hengl, C Kreutz, J Timmer, T Maiwald - bioinformatics, 2007 - academic.oup.com
Motivation: Mathematical modelling of biological systems is becoming a standard approach
to investigate complex dynamic, non-linear interaction mechanisms in cellular processes. …

Pathological tremors: Deterministic chaos or nonlinear stochastic oscillators?

J Timmer, S Häußler, M Lauk… - Chaos: An Interdisciplinary …, 2000 - pubs.aip.org
Pathological tremors exhibit a nonlinear oscillation that is not strictly periodic. We investigate
whether the deviation from periodicity is due to nonlinear deterministic chaotic dynamics or …

WNT and DKK determine hair follicle spacing through a reaction-diffusion mechanism

S Sick, S Reinker, J Timmer, T Schlake - Science, 2006 - science.org
Mathematical reaction-diffusion models have been suggested to describe formation of animal
pigmentation patterns and distribution of epidermal appendages. However, the crucial …

Identification of nucleocytoplasmic cycling as a remote sensor in cellular signaling by databased modeling

I Swameye, TG Müller, J Timmer… - Proceedings of the …, 2003 - National Acad Sciences
Considerable progress has been made in identifying the molecular composition of complex
signaling networks controlling cell proliferation, differentiation, and survival. However, to …

[PDF][PDF] Control of plant organ size by KLUH/CYP78A5-dependent intercellular signaling

…, S Kenz, M Gerstung, D MacLean, J Timmer… - Developmental cell, 2007 - cell.com
Plant organs grow to characteristic sizes that are genetically controlled. In animals, signaling
by mobile growth factors is thought to be an effective mechanism for measuring primordium …

Design principles of a bacterial signalling network

M Kollmann, L Løvdok, K Bartholomé, J Timmer… - Nature, 2005 - nature.com
Cellular biochemical networks have to function in a noisy environment using imperfect
components. In particular, networks involved in gene regulation or signal transduction allow only …

Nonlinear dynamical system identification from uncertain and indirect measurements

HU Voss, J Timmer, J Kurths - International Journal of Bifurcation …, 2004 - World Scientific
We review the problem of estimating parameters and unobserved trajectory components
from noisy time series measurements of continuous nonlinear dynamical systems. It is first …
