Unraveling looping efficiency of stochastic Cosserat polymers

Raushan Singh, Giulio Corazza

Understanding looping probabilities, including the particular case of ring closure or cyclization, of fluctuating polymers (e.g., DNA) is important in many applications in molecular biology and chemistry. In a continuum limit the configuration of a polymer ...

Viral Metagenomic Content Reflects Seawater Ecological Quality in the Coastal Zone

Grégoire Marie Octave Edouard Michoud, Stylianos Fodelianakis

Viruses interfere with their host's metabolism through the expression of auxiliary metabolic genes (AMGs) that, until now, are mostly studied under large physicochemical gradients. Here, we focus on coastal marine ecosystems and we sequence the viral metag ...

The Effect of European Integration on Swiss Energy Policy and Governance

Matthias Finger, Paul Adrianus Van Baal

The unique “Swiss way” of association with the European Union (EU) has received increasing attention in light of recent events such as Brexit as it is based on sectoral agreements without an overarching institutional framework. As such, Europeanization of ...
