Synthetic Aperture Radar Image Background Clutter Fitting Using SKS + MoM‐Based G0 Distribution
Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015 G0 distribution can accurately model various background clutters in the single‐look and multilook synthetic aperture radar (SAR) images and is one of the most important statistic models in the field of SAR image clutter modeling. However, the parameter estimation of G0 distribution is difficult, which greatly limits the application of the distribution.

Fractional Q$Q$‐curvature on the sphere and optimal partitions
Journal of the London Mathematical Society, Volume 112, Issue 6, December 2025.Abstract We study an optimal partition problem on the sphere, where the cost functional is associated with the fractional Q$Q$‐curvature in terms of the conformal fractional Laplacian on the sphere. By leveraging symmetries, we prove the existence of a symmetric minimal partition through a variational approach. A key ingredient in our analysis is a new

Euler Type Integrals and Integrals in Terms of Extended Beta Function
Journal of Mathematics, Volume 2014, Issue 1, 2014., 2014 We derive the evaluations of certain integrals of Euler type involving generalized hypergeometric series. Further, we establish a theorem on extended beta function, which provides evaluation of certain integrals in terms of extended beta function and certain special polynomials.

Estimation and Inference for Higher‐Order Stochastic Volatility Models With Leverage
Journal of Time Series Analysis, Volume 46, Issue 6, Page 1064-1084, November 2025.ABSTRACT Statistical inference—estimation and testing—for stochastic volatility models is challenging and computationally expensive. This problem is compounded when leverage effects are allowed. We propose efficient, simple estimators for higher‐order stochastic volatility models with leverage [SVL(p)$$ (p) $$], based on a small number of moment ...

Resource‐adaptive and OOD‐robust inference of deep neural networks on IoT devices
CAAI Transactions on Intelligence Technology, Volume 10, Issue 1, Page 115-133, February 2025.Abstract Efficiently executing inference tasks of deep neural networks on devices with limited resources poses a significant load in IoT systems. To alleviate the load, one innovative method is branching that adds extra layers with classification exits to a pre‐trained model, enabling inputs with high‐confidence predictions to exit early, thus reducing

Fading Evaluation in the 60 GHz Band in Line‐of‐Sight Conditions
International Journal of Antennas and Propagation, Volume 2014, Issue 1, 2014., 2014 An exhaustive analysis of the small‐scale fading amplitude in the 60 GHz band is addressed for line‐of‐sight conditions (LOS). From a measurement campaign carried out in a laboratory, we have estimated the distribution of the small‐scale fading amplitude over a bandwidth of 9 GHz. From the measured data, we have estimated the parameters of the Rayleigh,

Characterizing the Statistical Properties of SAR Clutter by Using an Empirical Distribution
International Journal of Antennas and Propagation, Volume 2013, Issue 1, 2013., 2013 The performances on the applications of synthetic aperture radar (SAR) data strongly depend on the statistical characteristics of the pixel amplitudes or intensities. In this paper, a new empirical model, called simply ℋ𝒢o, has been proposed to characterize the statistical properties of SAR clutter data over the wide range of homogeneous, heterogeneous,
