Using magnetocapacitance data, we directly determine the chemical potential jump at low temperatures of about 25 mK when the filling factor traverses the spin gap at n ­ 1 and the cyclotron gap at n ­ 2. The chemical potential jump for the cyclotron gap is found to increase proportionally to the magnetic field with a slope that is determined by an effective mass 0.071m0. The data yield a spin g...

The quantum yield and lifetimes of fluorescence and triplet state of the B820 subunit of core antenna of photosynthetic purple bacterium Rhodospirillum rubrum are reported at temperature range from 4.2 to 300K. The fluorescence quantum yield of B820 is strongly dependent on temperature. From 4.2 to about 200 K the yield remains nearly constant. A nonradiative decay process becomes activated aro...

in order to investigate the effective factors on the reduction of rain-fed wheat yield, an experiment in 45 fields was conducted in the township of bandar-gaz in 2012. in this research, all information such as crop management operations, seedbed preparation, cultivar, site preparation, seed sowing, weed combating, planting and harvesting issues, time of toxicant spraying, used seed rate were co...

Born from empirical observations in nonuniformly sampled multidimensional NMR data relating to gaps between sampled points, the Poisson-gap sampling method has enjoyed widespread use in biomolecular NMR. While the majority of nonuniform sampling schemes are fully randomly drawn from probability densities that vary over a Nyquist grid, the Poisson-gap scheme employs constrained random deviates t...
