The occurrence of these events is apparently chaotic but they obey the same statistical principles, a German-Chinese team of scientists around Jürgen Kurths from the Potsdam Institute for Climate Impact Research (PIK) reports in the current issue of the Proceedings of the National Academy of Sciences (PNAS).
A typical conversation using short messages starts with an initial message followed by a series of mutual sending and replying. The time between two such events shows the same typical pattern as an earthquake followed by a series of aftershocks.
Whereas intervals between two initial messages are usually long and erratic, intervals between replies are comparatively shorter – much like those between aftershocks following an earthquake.
Similar principles can be found in many other types of human communication like e-mail exchanges or internet chats. It is expected that precise mathematical descriptions of these events will allow for optimizing communication infrastructures in future. “Based on these results, we should even be able to derive ways for improving phone-line availability or the allocation of internet bandwidths,” says Jürgen Kurths.
The mathematical methods used by the researchers to investigate short messaging behaviour are also used in climate research to reveal the principles underlying the occurrence of extreme climate and weather events and to improve their predictability. Moreover, the principles which underlie modern communication are essential building blocks for computer simulations of social systems. Such simulations are currently developed at PIK.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
