Statistical classification for Raman spectra of tumoral genomic DNA
Claudio Durastanti, Emilio N. M. Cirillo, Ilaria De Benedictis +5
We exploit Surface-Enhanced Raman Scattering (SERS) to investigate aqueous droplets of genomic DNA deposited onto silver-coated silicon nanowires and we show that it is possible to…
Flexible-bandwidth Needlets
Claudio Durastanti, Domenico Marinucci, Anna Paola Todino
We investigate here a generalized construction of spherical wavelets/needlets which admits extra-flexibility in the harmonic domain, i.e., it allows the corresponding support in mu…
Parametric estimation for functional autoregressive processes on the sphere
Alessia Caponera, Claudio Durastanti
The aim of this paper is to define a nonlinear least squares estimator for the spectral parameters of a spherical autoregressive process of order 1 in a parametric setting. Further…
LASSO estimation for spherical autoregressive processes
Alessia Caponera, Claudio Durastanti, Anna Vidotto
The purpose of the present paper is to investigate on a class of spherical functional autoregressive processes in order to introduce and study LASSO (Least Absolute Shrinkage and S…
Aliasing effects for random fields over spheres of arbitrary dimension
Claudio Durastanti, Tim Patschkowski
In this paper, aliasing effects are investigated for random fields defined on the d-dimensional sphere and reconstructed from discrete samples. First, we introduce the concept of a…
On normal approximations for the two-sample problem on multidimensional tori
Solesne Bourguin, Claudio Durastanti
In this paper, quantitative central limit theorems for -statistics on the -dimensional torus defined in the framework of the two-sample problem for Poisson processes are deri…
