An end-user perspective on Organ-on-a-Chip: Assays and usability aspects

Abidemi Junaid, Alireza Mashaghi, Thomas Hankemeier, Paul Vulto
2017 Current Opinion in Biomedical Engineering  
Although convenient in a proof-of-concept phase, none of the publications researched, showed an easy to use approach for connecting an external pump system by non-expert end-users.  ...  Although very simple to use for the non-expert end-user, the bidirectionality of the flow is seen as a disadvantage by some. Integration of pumps is an alternative solution to this [12,27e31] .  ...  Appendix A.

Tangent: Automatic Differentiation Using Source Code Transformation in Python [article]

Bart van Merriënboer, Alexander B. Wiltschko, Dan Moldovan
2017 arXiv   pre-print
It takes numeric functions written in a syntactic subset of Python and NumPy as input, and generates new Python functions which calculate a derivative.  ...  This approach to automatic differentiation is different from existing packages popular in machine learning, such as TensorFlow and Autograd.  ...  We do this by constructing a control flow graph (CFG) from the AST in order to determine which variables are active (a form of forward dataflow analysis).  ...
