Reglero. This work will never be produced without kindly help and assistance of professors Francisco Herrera and Antonio Gonzáles. And I am gratefull to Rocio Romero for providing me NSGA II description.

A reduction method of ODEs not possessing Lie point symmetries makes use of the so called λ-symmetries (C. Muriel and J. L. Romero, IMA J. Appl. Math. 66, 111-125, 2001). The notion of covering for an ODE Y is used here to recover λ-symmetries of Y as nonlocal symmetries. In this framework, by embedding Y into a suitable system Y ′ determined by the function λ, any λ-symmetry of Y can be recove...

There is a necessity to develop in vitro methods for testing embryotoxicity (Romero et al., 2015) [1]. We studied the progress of D3 mouse embryonic stem cells differentiation exposed to model embryotoxicants and non-embryotoxicants chemicals through the expression of biomarker genes. We studied a set of 16 different genes biomarkers of general cellular processes (Cdk1, Myc, Jun, Mixl, Cer and ...
