On characterization of the Cauchy law by sample mean properties

Lietuvos Matematikos Rinkinys, 2004
The characterization of Cauchy distribution by assuming the identical distribution of a monomial and sample mean has been considered by B. Ramachandran, C.R. Rao, Y.H. Wang and other authors.

Asymptotic properties of maximum likelihood estimator for some discrete distributions generated by

Statistica, 2013
In large-scale biomolecular sysrems there are frequency distribuions with properties like Stable Laws. It is of interest to construct such frequency distributions. In the present article we consider Cauchy stable law. The large-sample distribution of the

Spherical matrix distributions and cauchy quotients [PDF]

Statistics & Probability Letters, 1989
It is shown that matrix quotients of submatrices of a spherical matrix are distributed as matrix Cauchy. This generalizes known results for scalar ratios of independent normal variates. The derivations are simple and make use of the theory of invariant measures on manifolds.

A Versatile Materials Class for Solution‐Processed Optics and Photonics Based On Titanium Oxide Hydrates and Polyalcohols: A Perspective

Advanced Materials, EarlyView.
A new, solution‐processable class of optical materials based on molecular hybrids of metal oxide hydrates and commodity polymers is discussed here, including their synthesis, processing into thin films, patterning, and photonic structures realized to date.

The Infinitely Divisible Characteristic Function of Compound Poisson Distribution as the Sum of Variational Cauchy Distribution

Journal of Physics: Conference Series, 2019
The new particular compound Poisson distribution is introduced as the sum of independent and identically random variables of variational Cauchy distribution with the number of random variables has Poisson distribution.

Adaptive Twisting Metamaterials

Advanced Materials, EarlyView.
This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

Sediment‐Resistant Marine Antifouling Coating Based on Amphiphilic Copolymer Brushes Bearing Sulfobetaine and Isobornyl Pendants

Advanced Materials Interfaces, EarlyView.
Amphiphilic copolymer coatings comprising sulfobetaine methacrylate (SBMA) and isobornyl methacrylate (IBMA) are reported, synthesized via SI‐ATRP, that resist biological fouling and sediment accumulation. The copolymer coating with an SBMA:IBMA feed molar ratio of 1:1 is optimal for reducing diatom adhesion and sediment adsorption.

“Three‐Color” Chemical Selectivity between Oxide, Nitride, and Silicon: Area‐Selective Deposition of Metal Oxide and Polymer on SiN and Si‐H versus SiO2

Advanced Materials Technologies, EarlyView.
Molybdenum hexafluoride as a pretreatment is able to create a chemical contrast between SiN and SiO2 surfaces via selective fluorine passivation of the oxide. One dose of MoF6 enabled 9.7 nm of selective deposited TiO2 on SiN versus SiO2 with selectivity >0.92 on a nanoscale SiN/SiO2 patterned surface.

Smooth Kernel Estimation of a Circular Density Function: A Connection to Orthogonal Polynomials on the Unit Circle

Journal of Probability and Statistics, 2018
The circular kernel density estimator, with the wrapped Cauchy kernel, is derived from the empirical version of Carathéodory function that is used in the literature on orthogonal polynomials on the unit circle.

The NSCT-HMT Model of Remote Sensing Image Based on Gaussian-Cauchy Mixture Distribution

IEEE Access, 2018
The nonsubsampled Contourlet transform (NSCT) not only retains the characteristics of Contourlet transform, but also has the good characteristic of shift-invariance, which plays a significant role in denoising, fusion, and segmentation of texture-rich ...
