Optimizing defence, counter-defence and counter-counter defence in parasitic and trophic interactions -- A modelling studyJul 10 2019In host-pathogen interactions, often the host (attacked organism) defends itself by some toxic compound and the parasite, in turn, responds by producing an enzyme that inactivates that compound. In some cases, the host can respond by producing an inhibitor ... More
The dynamically changing publication universe as a reference point in national impact evaluation: A counterfactual case study on the Chinese publication growthJan 16 2018Jan 25 2018National bibliometric performance is commonly measured via relative impact indicators which appraise absolute national values through a global environment. Consequenty the resulting impact values mirror changes in the national performance as well as in ... More
Exploration of Reproducibility Issues in Scientometric Research Part 2: Conceptual ReproducibilityApr 13 2018This is the second part of a small-scale explorative study in an effort to assess reproducibility issues specific to scientometrics research. This effort is motivated by the desire to generate empirical data to inform debates about reproducibility in ... More
Exploration of reproducibility issues in scientometric research Part 1: Direct reproducibilityApr 13 2018This is the first part of a small-scale explorative study in an effort to start assessing reproducibility issues specific to scientometrics research. This effort is motivated by the desire to generate empirical data to inform debates about reproducibility ... More
Temperature-dependent templated growth of porphine thin films on the (111) facets of copper and silverJul 02 2014The templated growth of the basic porphyrin unit, free-base porphine (2H-P), is characterized by means of X-ray photoelectron spectroscopy (XPS) and near-edge X-ray absorption fine-structure (NEXAFS) spectroscopy measurements and density functional theory ...

CALYPSO view of SVS 13A with PdBI: Multiple jet sourcesJul 07 2017Aims. We wish to clarify the origin of the multiple jet features emanating from the binary protostar SVS 13A (= VLA4A/VLA4B). Methods. We used the Plateau de Bure Interferometer to map at 0.3-0.8" (~70-190 au) dust emission at 1.4 mm, CO(2-1), SiO(5-4), ... More
