A Framework for Executable Systems Modeling
<p>Systems Modeling Language (SysML), like its parent language, the Unified Modeling Language (UML), consists of a number of independently derived model languages (i.e. state charts, activity models etc.) which have been co-opted into a single modeling framework. This, together with the lack of an …

Systems modeling of quantitative kinetic data identifies receptor tyrosine kinase-specific resistance mechanisms to MAPK pathway inhibition in cancer
Targeted cancer therapeutics have seen constraint in clinical efficacy due to resistance. Indicators for resistance may include genetic mutations or protein-level overexpression of targeted or bypass receptor tyrosine kinases (RTKs). While the latter is often attributed to gene amplification, …
