On the optimality of the aggregate with exponential weights for low temperatures
aggregation empirical process Gaussian approximation Gibbs estimators
2013/4/28
Given a finite class of functions F, the problem of aggregation is to construct a procedure with a risk as close as possible to the risk of the best element in the class. A classical procedure (PAC-Ba...
Interaction of Atomic and Molecular Hydrogen with Tholin Surfaces at Low Temperatures
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/27
We study the interaction of atomic and molecular hydrogen with a surface of tholin, a man-made polymer considered to be an analogue of aerosol particles present in Titan's atmosphere, using thermal pr...
Phosphorus Spin Coherence Times in Silicon at Very Low Temperatures
magnetic resonance donor spins in silicon quantum computing
2010/10/27
Phosphorus donor spin coherence in isotopically pure 28 silicon is measured at very low temperatures using pulsed electron spin resonance. The isolated spin T2 varies unexpectedly with phosphorus conc...
