The main objective of the journal *MathematicS in Action* is to promote the interactions of Mathematics with other scientific fields (Biology, Medicine, Economics, Computer Science, Physics, Chemistry, Mechanics, Environmental sciences, Engineering sciences, etc.) by publishing articles at their interfaces. These articles must be useful and globally accessible to both communities. Thus, the journal favours articles written by ay least two authors, one of them being a mathematician, the other one belonging to another scientific community.

The papers should address modelling issues (conception, analysis and validation of models), numerical and/or experimental methods.

They should preferably include both a mathematical part and, at choice, numerical or experimental results.

They should be very pedagogical on the motivations and the expected impact in both disciplines.

Each submitted paper will be evaluated equally for its mathematical quality and for its interest to the concerned application field. To be accepted a paper needs to be of the highest scientific quality, original, and strongly interdisciplinary.

The Journal is an electronic publication and all articles are freely available. However, each year a printed version is sent to a selection of libraries.

News - The journal MathS in Action calls for papers in the field of « High Performance Computing and Mathematics with industrial applications »
