A formalization of one of the main claims of “Cortex reorganization of Xenopus laevis eggs in strong static magnetic fields” by Mietchen et al. 2005¹

1.Introduction

Mietchen et al. [2] state that “A complex reorganization of cortical pigmentation was found in dejellied eggs as a function of the magnetic field and the field exposure time”. We present here a formalization of the main scientific claim from this quote by using a semantic template called the super-pattern [1].

2.Formalization

Our formalization looks as follows:

In the context class, we use the class “dejellied fertilizable stage VI Xenopus laevis oocyte” (Q107644116) from Wikidata. In the subject class, we use the class “strong static magnetic field” (Q107644241) from Wikidata. In the object class, we use the class “cell cortex” (Q5058180) from Wikidata.

3.RDF code

This is our formalization as a nanopublication in TriG format:
