Statement complementing the EFSA Scientific Opinion on the assessment of genetically modified oilseed rape MS11 for food and feed uses, import and processing, under Regulation (EC)...
Published 2022-03-01“…Abstract In a previous scientific opinion on application EFSA‐GMO‐BE‐2016‐138, the EFSA Panel on Genetically Modified Organisms (GMO Panel) could not conclude on the comparative analysis and on the food/feed safety assessment of genetically modified (GM) oilseed rape (OSR) MS11 because of the lack of an appropriate compositional data set. Following a request from the European Commission, the GMO Panel assessed additional information related to OSR MS11 to complement the original scientific opinion. …”

Compositional Lotka-Volterra describes microbial dynamics in the simplex.
Published 2020-05-01“…We derive a new nonlinear dynamical system for microbial dynamics, termed "compositional" Lotka-Volterra (cLV), unifying approaches using generalized Lotka-Volterra (gLV) equations from community ecology and compositional data analysis. On three real datasets, we demonstrate that cLV recapitulates interactions between relative abundances implied by gLV. …”

Chemical interactions in Ti doped MgB2 superconducting bulk samples and wires
Published 2005“…X-ray diffraction data, TEM and elemental mapping in the NanoSIMS confirmed the surprising suggestion that samples synthesized at high pressure from Mg and B with Ti additions contain a titanium hydride. These new compositional data support the idea that reactive metal additions are extremely beneficial in MgB2 wires and bulk materials because they preferentially adsorb deleterious impurities from the superconducting matrix. © 2005 IOP Publishing Ltd.…”
