Computational methods for integrating metabolomics data with metabolic engineering strain design
… cellular metabolites, “metabolomics”, provides data ideal for applications in metabolic engineering. However, many of the computational tools for strain design are built around Flux Balance Analysis (FBA) and were developed using assumptions that preclude direct integration of metabolomics data …

Analysing rounding data using radial basis function neural networks model
Unspecified counting practices used in a data collection may create rounding to certain ‘based’ number that can have serious consequences on data quality. Statistical methods for analysing missing data are commonly used to deal with the issue but it could actually aggravate the problem. Rounded …
