Lagrangians for Biological Models [PDF]
Journal of Nonlinear Mathematical Physics, 2012 We show that a method presented in [S.L. Trubatch and A. Franco, Canonical Procedures for Population Dynamics, J. Theor. Biol. 48 (1974), 299-324] and later in [G.H. Paine, The development of Lagrangians for biological models, Bull. Math. Biol. 44 (1982) 749-760] for finding Lagrangians of classic models in biology, is actually based on finding the ...

Modelling Biological Rhythms [PDF]
Current Biology, 2008 With our growing awareness of the complexity underlying biological phenomena, our need for computational models becomes increasingly apparent. Due to their properties, biological clocks have always lent themselves to computational modelling. Their capacity to oscillate without dampening--even when deprived of all rhythmic environmental information ...

A Biological Model of Unions [PDF]
American Economic Journal: Applied Economics, 2009 This paper applies principles from evolutionary biology to the study of unions. We show that unions that implement the preferred wage and organizing policies of workers will be displaced in evolutionary competition by unions that either extract less from firms, allowing them to live longer, or spend more on union organizing, or both. This implies that

Robust Modelling of Biological Neuroregulators [PDF]
2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2005 The modelling of biological neuroregulated systems is usually complex because of their non-structured and distributed architecture. Software agents are a very useful tool to use in the modelling of this kind of systems, allowing increasing the model with characteristics which are not present in the biological equivalent. This work proposes a model of a

On validation and invalidation of biological models [PDF]
BMC Bioinformatics, 2009 Very frequently the same biological system is described by several, sometimes competing mathematical models. This usually creates confusion around their validity, ie, which one is correct. However, this is unnecessary since validity of a model cannot be established; model validation is actually a misnomer.

Internal Models in Biological Control [PDF]
Annual Review of Control, Robotics, and Autonomous Systems, 2019 Rationality principles such as optimal feedback control and Bayesian inference underpin a probabilistic framework that has accounted for a range of empirical phenomena in biological sensorimotor control. To facilitate the optimization of flexible and robust behaviors consistent with these theories, the ability to construct internal models of the motor ...

Of (Biological) Models and Simulations [PDF]
MOJ Proteomics & Bioinformatics, 2016 Modeling and simulation are recognized as important aspects of the scientific method for more than 70 years but its adoption in biology has been slow. Debates on its representativeness, usefulness, and whether the effort spent on such endeavors is worthwhile, exist to this day.

At the Biological Modeling and Simulation Frontier [PDF]
Pharmaceutical Research, 2009 We provide a rationale for and describe examples of synthetic modeling and simulation (M&S) of biological systems. We explain how synthetic methods are distinct from familiar inductive methods. Synthetic M&S is a means to better understand the mechanisms that generate normal and disease-related phenomena observed in research, and how compounds of ...

Generic model for biological regulation [PDF]
F1000Research, 2022 Abstract Substantial portion of molecules in an organism is involved in regulation of a wide spectrum of biological processes. Several models have been presented for various forms of biological regulation, including gene expression regulation and physiological regulation; however, a generic model is missing.

Duplication Models for Biological Networks [PDF]
Journal of Computational Biology, 2003 Are biological networks different from other large complex networks? Both large biological and non-biological networks exhibit power-law graphs (number of nodes with degree k, N(k) ~ k-b) yet the exponents, b, fall into different ranges. This may be because duplication of the information in the genome is a dominant evolutionary force in shaping ...
