Detailed chemical kinetic modeling of gas-phase reactions can result in automatically generated mechanisms that contain thousands of reactions. In this paper, we describe the development of a rule-based expert system tool that organizes these reactions into classes such as hydrogen abstraction and beta scission. We have developed 29 simple classification rules, 20 complex (well-skipping) classi...

1 RuleML is a family of XML languages whose modular system of schemas permits high-precision (Web) rule interchange. The family’s top-level distinction is deliberation rules vs. reaction rules. In this paper we address the Reaction RuleML subfamily of RuleML and survey related work. Reaction RuleML is a standardized rule markup/serialization language and semantic interchange format for reaction...

background neuroblastoma is the most common extracranial malignant solid tumor in children under 5 years, and it is characterized by wide clinical and biological heterogeneity. n-myc oncogene amplification is considered to be one of the most important prognostic factors used to evaluate survival in these patients. objectives the aim of our study was to determine amplification of the n-myc oncog...

The mesoscopic reaction-diffusion master equation (RDME) is a popular modeling framework frequently applied to stochastic reaction-diffusion kinetics in systems biology. The RDME is derived from assumptions about the underlying physical properties of the system, and it may produce unphysical results for models where those assumptions fail. In that case, other more comprehensive models are bette...
