CiteSeerX — Submitted to the Astrophysical Journal

CiteSeerX Details Isaac Councill Lee Giles Pradeep Teregowda The uniformity of the helium to hydrogen abundance ratio in X ray emitting intracluster medium ICM is one of the commonly adopted assumptions in X ray analyses of galaxy clusters and cosmological constraints derived from these measurements In this work we investigate the effect of He sedimentation

Probing quantum coherence in single atom electron

The demonstration of ESR measurements at 4 K should make ESR STM and quantum sensing 6 7 possible in many existing STM systems operating at liquid helium temperature The ability to use this technique for a broad range of tunnel currents and temperatures allows us to investigate control and distinguish decoherence

Purifying Detecting and Characterizing Proteins

We then consider general methods for detecting or assaying specific proteins including the use of radioactive compounds for tracking biological activity Finally we discuss several techniques for characterizing a protein s mass sequence and three dimensional structure

The Big Stretch Part 1 TASC

SED traces its roots per Setterfield back to the father of Quantum physics himself Planck Also others including Einstein further researched and developed this model Another Nobel laureate de Broglie wrote in 1962 a book that seems to have spearheaded further development of SED Suffice it to say this is arguably real physics
