Motivation: Speech recognition software has advanced to the point where it can be employed as a mode of input in perceptive environments; however, current speech recognition techniques require low-noise signals to achieve resonable recognition rates. Such signals can be obtained from close-talking microphones, but we believe that it is possible to obtain similar signal quality from a large micr...

An effective analytical method for calculating energy spectra of cosmic-ray muons at large depths of homogeneous media is developed. The method allows to include an arbitrary (decreasing) muon spectrum at the medium boundary and the energy dependence of both discrete (radiative and photonuclear) and continuous (ionization) muon energy losses, with resonable requirements for the high-energy beha...

We analyze doping dependent spectral intensities and Fermi surface maps obtained recently in Nd2−xCexCuO4±δ (NCCO) via high resolution ARPES measurements, and show that the behavior of this electron-doped compound can be understood as the closing of a Mott (pseudo) gap, leading to a quantum critical point just above optimal doping. The doping dependence of the effective Hubbard U adduced by com...

We calculate the baryon asymmetry of the Universe which would arise during a first order electroweak phase transition due to minimal standard model processes. It agrees in sign and magnitude with the observed baryonic excess, for resonable KM parameters and mt in the expected range, and plausible values of bubble velocity and other high temperature effects. Research supported in part by NSF-PHY...

Properties of Tolman-Bondi (TB) model produced by two set of initial conditions, 1) fractal density and simultaneous bang time and 2) fractal density and linear Hubble law, are studied. It is shown for the first set that for some physical resonable values of parameters of the model, the central density and the cosmological density parameter Ω0, an area of compatibility of initial conditions has...

The early Universe inflation [11] is well known as a promising theory to explain the origin of large scale structure of the Universe, a causal theory for the origin of primordial density fluctuations which may explain the observed density inhomogeneities and cosmic microwave fluctuations in the very early Universe, and to solve the early universe pressing problems for the standard hot big bang ...
