Submaximal exercise testing at low altitude for prediction of exercise tolerance at high altitude

Johannes Burtscher

Annually, thousands of air travellers visit high altitude destinations to enjoy hiking tours to attractions in surrounding areas. However, many of them are not adequately trained, not sufficiently acclimatized and/or may suffer from pre-existing diseases. ...

A locally calibrated, late glacial Be-10 production rate from a low-latitude, high-altitude site in the Peruvian Andes

Katherine Colby Leonard

Well-dated records of tropical glacier fluctuations are essential for developing hypotheses and testing proposed mechanisms for past climate changes. Since organic material for radiocarbon dating is typically scarce in low-latitude, high-altitude environme ...

Widespread Signals of Convergent Adaptation to High Altitude in Asia and America

Matthieu Foll

Living at high altitude is one of the most difficult challenges that humans had to cope with during their evolution. Whereas several genomic studies have revealed some of the genetic bases of adaptations in Tibetan, Andean, and Ethiopian populations, relat ...

Dealing with Mid-Air Collisions in Dense Collective Aerial Systems

Dario Floreano, Jean-Christophe Zufferey, Severin Leven

The idea of creating collective aerial systems is appealing because several rather simple flying vehicles could join forces to cover a large area in little time in applications such as monitoring, mapping, search and rescue, or airborne communication relay ...

Long-term changes in annual maximum snow depth and snowfall in Switzerland based on extreme value statistics

Juliette Ferial Blanchet

Mountain snow cover is an important source of water and essential for winter tourism in Alpine countries. However, large amounts of snow can lead to destructive avalanches, floods, traffic interruptions or even the collapse of buildings. We use annual maxi ...

Near-obstacle flight with small UAVs

Dario Floreano, Jean-Christophe Zufferey, Antoine Beyeler

Autonomous flight in confined or cluttered environments such as houses or urban canyons requires high manoeuvrability, fast mapping from sensors to actuators and very limited overall system weight. Although flying animals are well capable of solving this p ...
