L-SYSTEM DESCRIPTION OF SUBDIVISION CURVES [PDF]
Summary: In recent years, subdivision has emerged as a major geometric modeling technique. Algorithms for generating subdivision curves are often specified in terms of iterated matrix multiplication. Each multiplication maps a globally indexed sequence of points that represents a coarser approximation of the curve onto a longer sequence that represents

A constraint-based modelling approach to metabolic dysfunction in Parkinson's disease
One of the hallmarks of sporadic Parkinson's disease is degeneration of dopaminergic neurons in the pars compacta of the substantia nigra. The aetiopathogenesis of this degeneration is still not fully understood, with dysfunction of many biochemical ...

Stochastic thermodynamics of all-to-all interacting many-body systems
We provide a stochastic thermodynamic description across scales for N identical units with all-to-all interactions that are driven away from equilibrium by different reservoirs and external forces.

Thermodynamics of non-elementary chemical reaction networks
We develop a thermodynamic framework for closed and open chemical networks applicable to non-elementary reactions that do not need to obey mass action kinetics.

Adaptable transition systems [PDF]
We present an essential model of adaptable transition systems inspired by white-box approaches to adaptation and based on foundational models of component based systems. The key feature of adaptable transition systems are control propositions, imposing a

The paper studies stability in L systems using a new approach. Given an L system G, a word w is said to be k-stable in G if, once w occurs in a derivation, the derivation can proceed no more than k steps before the next occurrence of w. The set of k-stable words in an L system is called by the author the k-stable language of the system.

Negative differential response in chemical reactions
Reaction currents in chemical networks usually increase when increasing their driving affinities. But far from equilibrium the opposite can also happen. We find that such negative differential response (NDR) occurs in reaction schemes of major biological

Evolving L-Systems in a Competitive Environment [PDF]
Lindenmayer systems (L-systems) have been developed to model plant growth by repeatedly applying production rules to an initial axiom, and serve as a model for genetically driven growth processes found in nature. A simulation method is proposed to evolve their phenotypic representations through competition in a heterogeneous environment to further ...

A market-based approach to recommender systems
Recommender systems have been widely advocated as a way of coping with the problem of information overload for knowledge workers. Given this, multiple recommendation methods have been developed.
