Creating a neuroprosthesis for active tactile exploration of textures

Intracortical microstimulation (ICMS) of the primary somatosensory cortex (S1) can produce percepts that mimic somatic sensation and, thus, has potential as an approach to sensorize prosthetic limbs. However, it is not known whether ICMS could recreate act ...

Stacking transition in rhombohedral graphite

Fabrizio Carbone, Ivan Madan, Gabriele Berruto, Tatiana Latychevskaia, Servet Ozdemir

Few-layer graphene (FLG) has recently been intensively investigated for its variable electronic properties, which are defined by a local atomic arrangement. While the most natural arrangement of layers in FLG is ABA (Bernal) stacking, a metastable ABC (rho ...

Feedback and Mediation in Causal Inference Illustrated by Stochastic Process Models

Mats Julius Stensrud

The concept of causality is naturally related to processes developing over time. Central ideas of causal inference like time-dependent confounding (feedback) and mediation should be viewed as dynamic concepts. We shall study these concepts in the context o ...

Inferring species interactions in ecological communities: a comparison of methods at different levels of complexity

Andrea Rinaldo, Andrea Giometto, Francesco Carrara, Florian Altermatt

Natural communities commonly contain many different species and functional groups, and multiple types of species interactions act simultaneously, such as competition, predation, commensalism or mutualism. However, experimental and theoretical investigat ...

Phenotypic heterogeneity in metabolic traits among single cells of a rare bacterial species in its natural environment quantified with a combination of flow cell sorting and NanoSIMS

Anders Meibom, Stéphane Laurent Escrig, Martin Ackermann

Populations of genetically identical microorganisms residing in the same environment can display marked variability in their phenotypic traits; this phenomenon is termed phenotypic heterogeneity. The relevance of such heterogeneity in natural habitats is u ...

Impact of the urbanization process on connectivity and genetic diversity - a spatially explicit simulation approach

Stéphane Joost, Estelle Rochat, Ivo Widmer

Urbanization leads to fragmentation, degradation or loss of natural environments and reduces connectivity between remaining habitat patches. This affects dispersal and establishment of species and their genes and might have adverse effects on biodiversity ...

Restoring Natural Sensory Feedback in Real-Time Bidirectional Hand Prostheses

Silvestro Micera, Marco Capogrosso, Stanisa Raspopovic, Francesco Maria Petrini, Jacopo Rigosa, Marco Bonizzato

Hand loss is a highly disabling event that markedly affects the quality of life. To achieve a close to natural replacement for the lost hand, the user should be provided with the rich sensations that we naturally perceive when grasping or manipulating an o ...

Invasion by Fallopia spp. in a French upland region is related to anthropogenic disturbances

Thomas Spiegelberger

Within Europe, mountain ecosystems are generally less invaded by exotic plant species than are lowland areas. This pattern is commonly attributed to climatic harshness, which limits invasive species presence, and higher propagule pressure and rates of dist ...

Emerging predictable features of replicated biological invasion fronts

Andrea Rinaldo, Andrea Giometto, Francesco Carrara, Florian Altermatt

Biological dispersal shapes species' distribution and affects their coexistence. The spread of organisms governs the dynamics of invasive species, the spread of pathogens, and the shifts in species ranges due to climate or environmental change. Despite its ...

Gut-associated microbes of Drosophila melanogaster

Bruno Lemaitre, Nichole Broderick

There is growing interest in using Drosophila melanogaster to elucidate mechanisms that underlie the complex relationships between a host and its microbiota. In addition to the many genetic resources and tools Drosophila provides, its associated microbiota ...
