GEKG: generalized eruptive keratoacanthoma of Grzybowski KA: keratoacanthoma PDT: photodynamic therapy INTRODUCTION Generalized eruptive keratoacanthoma of Grzybowski (GEKG), a rare variant of keratoacanthoma (KA), affects widespread areas of the skin and mucous membranes. First described in 1950, this condition is exceptionally difficult to treat. Systemic retinoids or cyclophosphamide, althou...

The primary focus of this article is the provision of tests for additional conditional moment constraints in cross-section or short panel data contexts. The principal contribution is the explicit incorporation of conditional moment restrictions defining the maintained hypothesis in the formulation of the test statistics thus mirroring that of the classical parametric likelihood setting by defin...

Cepstral normalization has been popularly used as a powerful approach to produce robust features for speech recognition. Good examples of approaches include the well known Cepstral Mean Subtraction (CMS) and Cepstral Mean and Variance Normalization (CMVN), in which either the first or both the first and the second moments of the Mel-frequency Cepstral Coefficients (MFCCs) are normalized [1, 2]....

We have generalized the ABCD propagation law, Q(2) = (AQ(1) + B)/(CQ(1) + D), for an optical system by introducing a generalized complex radius of curvature Q for a general optical beam. The real part of 1/Q is related to the mean radius of curvature of the wave front, while the imaginary part is related to the second moment of the amplitude of the beam.
