Finding patterns behind seemingly random events is the signature of a recent trio of research studies coming from the statistical physics group in Boston Universitys Department of Physics. Although describing physical phenomenon is not a surprising industry for research physicists, findings from this BU group increasingly wed phenomena associated with the inanimate world to those of animate beings -- finding commonalities between stock markets fluctuations, earthquakes, and heart rates, for example, or discovering similarities in mice, men, and other mammals for such fundamental phenomena as wake periods during slumber.
Eugene Stanley, a professor of physics and director of BUs Center for Polymer Studies, Plamen Ivanov, a research associate in the Center, and Kun Hu, a research assistant in physics, will discuss their findings March 22 at the American Physical Society meeting in Los Angeles.
The team sought to investigate the role the bodys internal clock, the circadian pacemaker, might have on heart performance either directly, through influencing cardiac dynamics such as heartbeat, or indirectly, through its influence on motor activity control. Their analyses of heartbeat dynamics from participants show a significant circadian rhythm, including a notable response at the circadian phase corresponding to 10 a.m., the time of day most often linked to adverse cardiac events in individuals with heart disease. Circadian rhythm, however, does not affect motor activity dynamics, according to their recent analyses, leading the researchers to speculate that the early-morning peak in cardiac risk is not related to circadian-mediated influences on motor activity.

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...

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...
