Adaptive cross-country optimization strategies in thermal soaring birds
iScienceSummary: Thermal soaring enables birds to perform cost-efficient flights. Although aerodynamic rules dictate the costs of flight, soaring species vary strongly in their morphologies and behavioral strategies. To quantify morphology-related differences in

Polymer chain scission at constant tension - an example of force-induced collective behaviour
, 2011 The breakage of a polymer chain of segments, coupled by anharmonic bonds with applied constant external tensile force is studied by means of Molecular Dynamics simulation.

Modelling sequences and temporal networks with dynamic community structures
Nature Communications, 2017 The description of temporal networks is usually simplified in terms of their dynamic community structures, whose identification however relies on a priori assumptions.

CalciSeg: A versatile approach for unsupervised segmentation of calcium imaging data
NeuroImageRecent advances in calcium imaging, including the development of fast and sensitive genetically encoded indicators, high-resolution camera chips for wide-field imaging, and resonant scanning mirrors in laser scanning microscopy, have notably improved the

Modularity and stability in ecological communities
Nature Communications, 2016 Modularity in food webs can be caused by spatial and temporal mismatches in interactions. Here, Jacopo Grilli, Tim Rogers and Stefano Allesina show that modularity, contrary to expectations, does not generally help stabilizing ecological communities.

Computational rationality and voluntary provision of public goods: an agent-based simulation model [PDF]
The issue of the cooperation among private agents in realising collective goods has always raised problems concerning the basic nature of individual behaviour as well as the more traditional economic problems.

Long-term tracking of social structure in groups of rats
Scientific ReportsRodents serve as an important model for examining both individual and collective behavior. Dominance within rodent social structures can determine access to critical resources, such as food and mating opportunities.
