Translating biochemical network models between different kinetic formats

Metabolic Engineering, 2009
Mechanistic biochemical network models describe the dynamics of intracellular metabolite pools in terms of substance concentrations, stoichiometry and reaction kinetics. Data from stimulus response experiments are currently the most informative source for in-vivo parameter estimation in such models.

A neural network model for limb trajectory formation

Biological Cybernetics, 1989
This paper deals with the problem of representing and generating unconstrained aiming movements of a limb by means of a neural network architecture. The network produced time trajectories of a limb from a starting posture toward targets specified by sensory stimuli. Thus the network performed a sensory-motor transformation.

Citations are forever: Modeling constrained network formation [PDF]

, 2014
Determining the extent to which citation flows, and hence bibliometric indicators based on them, reflect some intrinsic value of scientific works is an important task made very difficult by endogeneity issues. This paper presents an approach which allows to go beyond the abundant anecdotal evidence by testing whether the citation behavior is free from ...

Effect of Network Topology in Opinion Formation Models

2011
Simulations of consensus formation in networks of interacting agents have recently demonstrated that convergence to a small number of opinion clusters is more likely when the network is adaptive rather than static. In order to better model realistic social networks, we have extended an existing model of such a process, by the introduction of a ...

Edge-based models of network formation

2019
We present new network formation models, which are featured on the search process of edges instead of nodes. In the models, new nodes arrive sequentially and create connections with old nodes. Accordingly, the network forms and grows. There are two steps for a new node to search and create connections: 1. a new node finds a link/edge and both end-nodes,

Approximative kinetic formats used in metabolic network modeling

Biotechnology and Bioengineering, 2005
AbstractAn overview is presented of the different approximative enzyme kinetic formats that have been proposed for use in metabolic modeling studies. It is considered that the following four general properties are relevant for approximative kinetics: the rate must be proportional to enzyme level; at high metabolite concentrations, there is downward ...
