Journal of High Energy Astrophysics, 2018 We argue that if ultrahigh-energy (E > 10^10 GeV) cosmic rays are heavy nuclei (as indicated by existing data), then the pointing of cosmic rays to their nearest extragalactic sources is expected for 10^10.6 < E/GeV < 10^11. This is because for a nucleus of charge Ze and baryon number A, the bending of the cosmic ray decreases as Z/E with ...

Microscopes and Mass Spectrometers [PDF]
Journal of Proteomics & Bioinformatics, 2016 Proteomics is a relatively young discipline while pathology is one of the oldest forms of scientific inquiry. These two fields have different methods and aims, but have many areas of overlap and shared interests. Cultivation of synergistic projects between physicians who study static images of disease and biologists who study the dynamic environment ...

The Electrostatic Ion Beam Trap : a mass spectrometer of infinite mass range [PDF]
, 2013 We study the ions dynamics inside an Electrostatic Ion Beam Trap (EIBT) and show that the stability of the trapping is ruled by a Hill's equation. This unexpectedly demonstrates that an EIBT, in the reference frame of the ions works very similar to a ...
