Over the past few years there has been a growing interest among computer scientists and users for distributed computer systems such as the Internet. A distributed system consists of different independent computers in a network that appears to be a single coherent system for the users. At least one software component is present on each computer, which communicates with components that are on other computers, such as databases, web services or peer-to-peer applications that exchange data such as Skype, Kazaa or Napster. As all of these components are distributed and run at the same time, suitable theories and infrastructures are needed for an efficient coordination.
Guillen Scholten developed the MoCha coordination framework that consists of both models and software. It is capable of coordinating components from the outside (exogenously). As a result of this MoCha can change the behaviour of the system without needing to adjust the software components. It can also dynamically change the links between components. This characteristic is particularly useful when the components are mobile. MoCha can be used efficiently on Grids, in service-oriented architectures (SOAs), component-based software and in-home networks.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
