Resistance of plant communities to invasive species

Invasive species are nowadays considered as one of the most important threat to biodiversity. By displacing native species, modifying ecosystem functioning and causing substantial losses to agricultural production, they represent a menace to natural and ma ...

Mathematics in the Wind

Alfio Quarteroni, Nicola Parolini

In any sport or human endeavor, coaches regularly state “play to your strengths.” One might not guess that a land-locked, mountainous country like Switzerland would have strengths that would give them a chance at winning the oldest, most competitive sailin ...

The influence of competition from herbaceous vegetation and shade on simulated browsing tolerance of coniferous and deciduous saplings

Alexandre Buttler, Charlotte Vandenberghe, François Frelechoux

The ability of saplings to tolerate browsing (i.e. the ability to persist with reduced biomass and to compensate for biomass loss) is influenced by the level of stress and their growth strategies. Ultimately, insight into species-specific responses of sapl ...

Some results for long-range exclusion processes

Thomas Mountford

We examine the long-range exclusion process introduced by Spitzer and studied by Liggett and answer some of the open questions raised by Liggett. In particular, we show the existence of equilibria corresponding to bounded dual harmonic functions and that t ...

Reductive evolution and niche adaptation inferred from the genome of Mycobacterium ulcerans, the causative agent of Buruli ulcer

Stewart Cole

Mycobacterium ulcerans is found in aquatic ecosystems and causes Buruli ulcer in humans, a neglected but devastating necrotic disease of subcutaneous tissue that is rampant throughout West and Central Africa. Here, we report the complete 5.8-Mb genome sequ ...

High epitope expression levels increase competition between T cells

Marcel Salathé

Both theoretical predictions and experimental findings suggest that T cell populations can compete with each other. There is some debate on whether T cells compete for aspecific stimuli, such as access to the surface on antigen-presenting cells (APCs) or f ...

Competitive effects of herbaceous vegetation on tree seedling emergence, growth and survival: does gap size matter?

Alexandre Buttler, Charlotte Vandenberghe, François Frelechoux

Question: What is the effect of gap size on the seedling emergence, growth and survival of four common tree species in wooded pastures? Location: A pasture in the Jura mountains, Switzerland. Methods: Seeds were sown in a complete three-way factorial desig ...

Some fundamental (and often overlooked) considerations underlying the free ion activity and biotic ligand models

Trace metal bioavailability is often evaluated on the basis of steady-state models such as the free ion activity model (FIAM) and the biotic ligand model (BLM). Some of the assumptions underlying these models were verified by examining Pb and Zn uptake by ...

Push vs. Pull in Web-Based Network Management

Jean-Philippe Martin-Flatin

In this paper, we show how Web technologies can be used effectively to (i) address some of the deficiencies of traditional IP network management platforms, and (ii) render these expensive platforms redundant. We build on the concept of embedded management ...

Coexisting one-dimensional and three-dimensional spectral signatures in TaTe4

Giorgio Margaritondo, László Forró, Marco Grioni, Helmuth Berger

Using angle-resolved photoemission spectroscopy, we probe the electronic band structure of TaTe4 single crystal samples. Resistivity and optical measurements were also performed on the same samples. The experimental data indicate a combination of quasi-one ...
