Patterns of bryophyte and vascular plant richness in European subalpine springs
Alexandre Buttler, Lucia Sekulova
The diversity of spring habitats can be determined not only by local environmental conditions, but also by large-scale biogeographical effects. The effects can differ across various groups of organisms. We compared alpha-, beta- and gamma-diversity pattern ...
Springer Netherlands2012The genome of Dehalobacter restrictus - high gene redundancy for a restricted metabolism
Christof Holliger, Julien Maillard, Aamani Rupakula Boyanapalli, Hauke Smidt
Organohalide respiration (OHR) is a bacterial anaerobic respiratory metabolism dedicated to use halogenated compounds as terminal electron acceptors. OHR bacteria are strictly anaerobic microorganisms which use reductive dehalogenases (RdhA) as key enzymes ...
2012The role of feedback in morphological computation with compliant bodies
The generation of robust periodic movements of complex nonlinear robotic systems is inherently difficult, especially, if parts of the robots are compliant. It has previously been proposed that complex nonlinear features of a robot, similarly as in biologic ...
Springer Verlag2012Automated Reconstruction of Tree Structures using Path Classifiers and Mixed Integer Programming
Pascal Fua, Engin Türetken, Fethallah Benmansour
Although tracing linear structures in 2D images and 3D image stacks has received much attention over the years, full automation remains elusive. In this paper, we formulate the delineation problem as one of solving a Quadratic Mixed Integer Program (Q-MIP) ...
2012On the role of diversity in sparsity estimation
A major challenge in sparsity pattern estimation is that small modes are difficult to detect in the presence of noise. This problem is alleviated if one can observe samples from multiple realizations of the nonzero values for the same sparsity pattern. We ...
IEEE2011Testate amoeba analysis of lake sediments: impact of filter size and total count on estimates of density, species richness and assemblage structure
Testate amoebae are informative about palaeoecological conditions, but the methods generally used for their analyses in lake sediments differ from those used for their analyses in peats, making comparisons difficult. This study examines how filter mesh siz ...
2010Mathematical Modeling of T-Cell Experimental Data
T lymphocytes (T cells) are key components of the adaptive immune system. These cells are able to recognize an enormous variety of pathogens thanks to the great specificity of their trans-membrane proteins, the T cell receptors (TCRs). TCR diversity is cre ...
EPFL2010Importance of microstructural understanding for durable and sustainable concrete
This paper presents the importance of microstructural studies for understanding concrete durability. Three examples-sulfate attack; alkali silica reaction and bacteriogenic corrosion in sewers arc used to illustrate the pitfalls which can arise from conven ...
Crc Press-Taylor & Francis Group, 6000 Broken Sound Parkway Nw, Ste 300, Boca Raton, Fl 33487-2742 Usa2009On neutral metacommunity patterns of river basins at different scales of aggregation
Andrea Rinaldo, Enrico Bertuzzo
Neutral metacommunity models for spatial biodiversity patterns are implemented on river networks acting as ecological corridors at different resolution. Coarse-graining elevation fields (under the constraint of preserving the basin mean elevation) produce ...
2009The curse of taxonomic uncertainty in biogeographical studies of free-living terrestrial protists: a case study of testate amoebae from Amsterdam Island
Edward Mitchell, Thierry Jean Heger
Aim A current debate in microbial biogeography contrasts two views concerning the distribution of free-living microorganisms. The first view assumes a ubiquitous distribution, while the second view assumes that at least some species have limited geographic ...
