Does mycorrhizal specificity affect orchid decline and rarity? KU Leuven
• Premise of the study: Orchids rely on mycorrhizal fungi for seed germination, and many species maintain associations during later stages in their life cycle. Because of the critical dependence of orchids on fungi it has been suggested that the degree of mycorrhizal specificity may be associated with rarity and long-term survival of orchid species, especially in highly degraded or fragmented landscapes. To test this hypothesis, we compared ...
A cadaveric study of the structural anatomy of the sternoclavicular joint Vrije Universiteit Brussel
Pathologies of the sternoclavicular (SC) joint are infrequent and effective management is often hindered by a limited understanding of the anatomy. In this study, we did macroscopic evaluations of the ligaments, the intra-articular disc, and the articulating surfaces of 25 SC joints. After removal of the joint capsule, the articulating surfaces of the sternal end of clavicle and the sternum were evaluated and the intra-articular disc was ...
Light Gravitino Production in Association with Gluinos at the LHC Vrije Universiteit Brussel
We study the jets plus missing energy signature at the LHC in a scenario where the gravitino is very light and the gluino is the next-to-lightest supersymmetric particle and promptly decays into a gluon and a gravitino. We consider both associated gravitino production with a gluino and gluino pair production. By merging matrix elements with parton showers, we generate inclusive signal and background samples and show how information on the gluino ...
Cellular Changes that Accompany Shedding of Human Corneocytes Vrije Universiteit Brussel
Corneocyte desquamation has been ascribed to the following: 1) proteolytic degradation of corneodesmosomes (CDs); 2) disorganization of extracellular lamellar bilayers; and/or 3) "swell-shrinkage-slough'' from hydration/dehydration. To address the cellular basis for normal exfoliation, we compared changes in lamellar bilayer architecture and CD structure in D-Squame strips from the first versus fifth stripping ("outer'' vs. "mid''stratum corneum ...
Cryptic species in Iphisa elegans Gray, 1851 (Squamata: Gymnophthalmidae) revealed by hemipenial morphology and molecular data Vrije Universiteit Brussel
Iphisa elegans Gray, 1851 is a ground-dwelling lizard widespread over Amazonia that displays a broadly conserved external morphology over its range. This wide geographical distribution and conservation of body form contrasts with the expected poor dispersal ability of the species, the tumultuous past of Amazonia, and the previously documented prevalence of cryptic species in widespread terrestrial organisms in this region. Here we investigate ...
Beating the diffraction limit with perfect confinement in right-handed cavities Vrije Universiteit Brussel
We develop a novel approach to create optical resonators by applying the geometrical technique of transformation optics and we show that the fundamental diffraction limit can be overcome inside metamaterials with right-handed material parameters.
Amplifying optical gradient forces with metamaterials Vrije Universiteit Brussel
We demonstrate how transformation optics can be used to amplify optical gradient forces. We show how meta-materials allow to enhance optical forces between waveguides over several orders of magnitude, even when realistic losses are included.
Target monitoring in offshore windfarms—the need to understand cause–effect relationships in the marine benthos Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
In many European countries offshore windfarm projects are accompanied by obligatory environmental impact assessments, including baseline monitoring of the marine benthos and demersal fish. The effects of offshore windfarm developments on the benthic system are complex.
However, legal baseline monitoring merely allows for net effect descriptions but not for identifying and understanding the underlying processes. Instead, key processes ...

A call for hypotheses‐based benthos research in offshore windfarm environmental impact studies Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
Offshore windfarms are expected to affect substantially the structure and functioning of marine ecosystems. Collision risks for migrating birds and noise impact on marine mammals and fish are issues of major public concern. Less charismatic organisms, however, from marine algae through to benthic invertebrates and demersal fish receive far less attention. We contend that the benthos deserves much greater attention owing to the numerous ecosystem ...
