Cosmic rays at the highest energies
After a century of observations, we still do not know the origin of cosmic rays. I will review the current state of cosmic ray observations at the highest energies, and their implications for proposed acceleration models and secondary astroparticle fluxes. Possible sources have narrowed down with the confirmation of a GZK-like spectral feature. The anisotropy observed by the Pierre Auger Observ...
متن کاملAstrophysics at the Highest Energy Frontiers
I discuss recent advances being made in the physics and astrophysics of cosmic rays and cosmic γ-rays at the highest observed energies as well as the related physics and astrophysics of very high energy cosmic neutrinos. I also discuss the connections between these topics.
متن کاملThe Symplectic Penrose Kite
The purpose of this article is to view the Penrose kite from the perspective of symplectic geometry. Mathematics Subject Classification 2000. Primary: 53D20 Secondary: 52C23 Introduction The kite in a Penrose aperiodic tiling by kite and darts [8, 9] is an example of a simple convex polytope. By the Atiyah, Guillemin–Sternberg convexity theorem [1, 6], convex polytopes that are rational can be ...
متن کاملEffect of natural land covers on runoff and soil loss at the hill slope scale
Erosion plots were selected for characterizing the effects of main natural factors on runoff and soil loss in a semi-arid region. These erosion plots with an area of 40 m2 are located in the Kakhk experimental watershed in Gonabad County of Khorasan-e Razave Province in the north-eastern Iran. Data acquired from 2008 to 2015 include slope, aspect, soil texture and land covers (canopy...
متن کاملThe KITE Application Server Architecture
An application server represents a framework for server applications, which are programs that provide an API rather than a GUI and allow remote access to their functionality. The architecture of the Java-based application server KITE results from a generalization of the single-user desktop operating environment Oberon essentially by turning the global module list into a data structure associate...
