The Alexander von Humboldt-Foundation
The Alexander von Humboldt Foundation promotes academic cooperation between excellent scientists and scholars from abroad and from Germany. To this end, it grants more than 700 research fellowships and research awards annually. These allow scientists and scholars from all over the world to come to Germany to work on a research project they have chosen themselves together with a host and collabo...
متن کاملA. Von Humboldt Fellow.
We derive the kinematical constraints which characterize the decay of any massless particle in flat spacetime. We show that in perturbation theory the decay probabilities of photons and Yang-Mills bosons vanish to all orders; the decay probability of the graviton vanishes to one-loop order for graviton loops and to all orders for matter loops. A general power counting argument indicates in whic...
متن کاملAlexander von Humboldt Professorship Research Project : Foundations and Architectures for the Next Generation of Wireless Networks
Millimeter-wave (mm-Wave) cellular systems are a promising option for a very high data rate communication because of the large bandwidth available at mm-Wave frequencies. To compensate the large path-loss exponent in the mmWave range of the spectrum, directional beamforming with a large antenna gain at both the user side and base-station side is necessary; this boost the signal-to-noise ratio t...
متن کاملGrand challenges in geomagnetism and paleomagnetism
Geomagnetism and paleomagnetism is a broad sub-discipline of the Earth Sciences. I present the Grand Challenges from the perspective of a paleomagnetist and rock magnetist, hence I feel more comfortable with the paleomagnetic side of this short article than the geomagnetic side. Nevertheless, exciting things are happening in geomagnetism and the future is bright for both paleomagnetists and geo...

with the Regional Oceanic Modeling System (ROMS). The oceanic model simulated the climatological and interannual variation of temperature, salinity and currents (Penven et al. 2005). Fig. 1 shows a climatological simulation of sea surface temperature of Peru, emphasizing cold waters from coastal upwelling and warm waters from the north and offshore. This model will be used as boundary condition...
