Every topic is explained with clear, succinct study notes, examples and diagrams - and there are practice questions at the end of every page to test you on what you've learned (with answers and mark schemes included). We've covered all the crucial new elements of the Grade 9-1 course,...
Each Masterclass focuses on a different exam board (AQA or OCR A) and year group, allowing for detailed guidance and support. Participants can access video recordings of each class for later revision. The topic-based group lessons include explanations and exam-question walk-throughs. I discuss ...
The inverse problem of identifying the topology of biological networks from their time series responses is a cornerstone challenge in systems biology. We tackle this challenge here through the parameterization of S-system models. It was previously shown that parameter identification can be performed as...
Reactions schemes that describe the fluxes through glycolysis and the PEP/pyruvate node. Left:Case A. Growth on glycolytic PTS substrate and non-PTS substrates. State variableXrepresents all PTS components. Right:Case B. Growth on gluconeogenetic substrates. Values in parenthesis indicate the flux ...
The mark process generates a uniform random number each timeDis changed. These marks are used to update the original processXaccording to the adapted functional (3) in a process that is equivalent to the direct simulation ofX[12]. Heuristically, the DCFTP scheme works as follows. Since the ...
