While the state-of-the-art speech enhancement methods are focused on the modification of the noisy spectral amplitude, our recent findings demonstrate positive impact of incorporating the speech phase spectrum in speech enhancement. In this show and tell proposal, we demonstrate the recent progress towards utilizing the phase information in closed-loop iterative manner leading to the joint enha...

Correlations between 276 orthogonal electrocardiographic measurements and constitutional variables were made in 450 normal women, aged 18 to 90 years. Advancing age led to decreases in amplitudes, left QRS axis shift, rightward and superior displacement of the ST segment, and anterior shift of the T wave. QZ was absent in 1% of normal women over age 40. In the oldest subjects, Ry amplitude was ...

The nonlinear behavior of soils can significantly modify the wavelet radiated from vibrator trucks. In this paper, we describe a field experiment designed to measure the nonlinear response of a natural soil formation in the near-field of a vibrator truck. A 267-kN (30-ton) vibrator truck performed a step-sweep through a set of 201 discrete frequencies from 50-Hz to 10-Hz, which was repeated at ...

We study the four-point correlator of 1 2-BPS operators of weight 4 in N = 4 SYM, which are dual to massive KK modes in AdS 5 supergravity. General field-theoretic arguments lead to a partially non-renormalized form of the amplitude that depends on two a priori independent functions of the conformal cross-ratios. We explicitly compute the amplitude in the large N limit at one loop (order g 2) a...

Regularized adelic formulas for gamma and beta functions for arbitrary quasicharacters (either ramified or not) and in an arbitrary field of algebraic numbers are concretized as applied to one-class quadratic fields (and to the field of rational numbers). Applications to 4-tachyon tree string amplitudes, to the Veneziano (open strings) and Virasoro (closed strings) amplitudes as well as to mass...

We present results for the photoproduction helicity amplitudes of excited baryons obtained in the context of the 1/Nc expansion of QCD. The results show that, in order to get a satisfactory description of the observed photoproduction amplitudes, the sub-leading corrections in 1/Nc are important. We also find that, while onebody effective operators are dominant, there is some evidence for the ne...

New results from inelastic two-body scattering reactions are reviewed. Although predictions of SU(3), factorization and simple Regge theory are found to be qualitatively in agreement with the data, direct channel or absorption effects afford the simplest interpretation of the detailed features of the scattering amplitudes.

A new approach to the analysis of three body decays is presented. Model-independent results are obtained for the S-wave Kπ amplitude as a function of Kπ invariant mass. These are compared with results from K − π + elastic scattering, and the prediction of the Watson theorem , that the phase behavour be the same below Kη ′ threshold, is tested. Contributions from I = 1 2 and I = 3 2 are not reso...

In this letter we propose exact three-point correlation functions for N = 1 super-symmetric Liouville theory. Along the lines of [12] we propose a generalized special function which describe the three-point amplitudes. We consider briefly the so called reflection amplitudes in the supersymmetric case.
