How nickel-titanium nanometric-size particles change back to their memorised shapeUniversity of Constance physicists Daniel Mutter and Peter Nielaba have visualised changes in shape memory materials down to the nanometric scale in an article published in EPJB.

The activity of online communities does not grow in line with the number of users, according to a model recently published in the European Physical Journal B.The Internet has given rise to its own sorting devices. Among these, tagging consists in assigning user-chosen keywords to a piece of information (such as a digital image) to facilitate searches. Lingfei Wu, a researcher at the City University of Hong Kong’s Department of Media and Communication, used the tagging behaviour of social media application users to study the growth of online communities’ activity.

The conventional method for atomistic simulation, namely molecular dynamics (MD), is not well suited to resolve slow dynamical processes, that is processes associated with a system that gets trapped from time to time in deep local energy minima.
In a Colloquium paper in the European Physical Journal B, A. Kushima, J. Eapen, Ju Li, S. Yip and T. Zhu review the capabilities of biased molecular simulation methods such as metadynamics, autonomous basin climbing (ABC), strain-boost and adaptive boost simulations – methods designed to probe at the atomic level mechanisms that drive system-level behavior observable on macroscopic time scales.

A study recently published in European Physical Journal B presents observations of how complex systems synchronise over time.
Synchronisation occurs when individual elements in a complex network behave in line with each other. This applies to real-life examples such as the way neurons fire during an epileptic seizure or the phenomenon of crickets falling into step with one another.

Game theory has changed our way of thinking about socio-economic interaction, shedding light on the consequences of leaving individuals take their choices for the sake of their self-interest. As exemplified by the prisoner's dilemma, the prediction of this approach can be quite far from what welfare optimization would predict.

A new Colloquium article by I. Deretzis and A. La Magna published in EPJB reviews the possibilities offered by all-carbon electronics as well as elucidating drawbacks in view of future applications.

Modeling the transport of fluids in porous solids is a problem of general interest for its implications in construction engineering, industrial catalysis, hydrology, agriculture and geology. The classical approach uses an equation derived from continuum mechanics which is problematic and often gives incorrect predictions. When the porous medium presents many scales of variability the problem becomes intractable.
