Suppose that p ≥ 5 is prime, that F(z) ∈ S2k(Γ0(p)) is a newform, that v is a prime above p in the field generated by the coefficients of F , and that D is a fundamental discriminant. We prove non-vanishing theorems modulo v for the twisted central critical values L(F⊗χD, k). For example, we show that if k is odd and not too large compared to p, then infinitely many of these twisted L-values ar...

In this paper we calculate the asymptotics of various moments of the central values of Rankin-Selberg convolution L-functions of large level, thus generalizing the results and methods of W. Duke, J. Friedlander, and H. Iwaniec and of the authors. Consequences include convexity-breaking bounds, nonvanishing of a positive proportion of central values, and linear independence results for certain H...

Linear Discriminant Analysis (LDA) is a well-known technique to improve the discrimination among classes or reduce the dimensionality with minimum loss of discrimination. It is generally used as a part of the front-end of speech recognizer with the classes defined on phone or subphone level. LDA with subphone-level classes (such as tied states or individual Gaussian densities) shows superior pe...

In this study a fully polarimetric electromagnetic model for sea surface Mueller matrix is exploited, under low to moderate wind conditions, to design and experiment a Synthetic Aperture Radar (SAR) oil slick filter. The latter is simple and computer time effective. Experiments, accomplished over C-band Multi Look Complex (MLC) SIR-C/X-SAR data and L-band Single Look Complex (SLC) ALOS PalSAR d...
