Participatory design of livestock systems adapted to new climatic conditions

Climate change progressively makes obsolete the current agricultural production strategies built with respect to previous landmarks of average and extreme climatic situations. In order to remain viable in the expected climatic context farming systems will need to evolve both in their structure and management. Because farmers and extension services are the primary actors in agricultural producti...

The Brine Shrimp Artemia: Adapted to Critical Life Conditions

The brine shrimp Artemia is a micro-crustacean, well adapted to the harsh conditions that severely hypersaline environments impose on survival and reproduction. Adaptation to these conditions has taken place at different functional levels or domains, from the individual (molecular-cellular-physiological) to the population level. Such conditions are experienced by very few equivalent macro-plank...

Adapted to explore: reinforcement learning in Autistic Spectrum Conditions.

Recent studies have recorded a tendency of individuals with Autism Spectrum Conditions (ASC) to continually change their choices in repeated choice tasks. In the current study we examine if this finding implies that ASC individuals have a cognitive style that facilitates exploration and discovery. Six decision tasks were administered to adolescents with ASC and matched controls. Significant dif...

Spiders in Lyot Coronagraphs

In principle, suppression of on-axis stellar light by a coronagraph is easier on an unobscured aperture telescope than on one with an obscured aperture. Recent designs such as the apodized pupil Lyot coronagraph, the ‘band-limited’ Lyot coronagraph, and several variants of phase mask coronagraphs work best on unobscured circular aperture telescopes. These designs are developed to enable the dis...

Optical vortex coronagraphs on ground-based telescopes

The optical vortex coronagraph is potentially a remarkably effective device, at least for an ideal unobstructed telescope. Most groundbased telescopes however suffer from central obscuration and also have to operate through the aberrations of the turbulent atmosphere. This note analyzes the performance of the optical vortex in these circumstances and compares to some other designs, showing that...
