On stability estimations without any conditions of symmetry

Lietuvos Matematikos Rinkinys, 2023
Let X, X1, X2, ..., Xn be i.i.d. random variables. B. Ramachandran and C.R. Rao have proved that if distributions of sample mean ‾X = ‾X(n) = (X1 + ⋯ + Xn)/n and monomial X are coincident at least at two points n = j1 and n = j2 such that log j1/ log j2

The Nonlinear Visco‐Hyperelastic Damage Mechanics of Individual Electrospun Polycaprolactone Fibers: Experiments and Modeling

Advanced Engineering Materials, EarlyView.
This study investigates the complex mechanics of individual electrospun polycaprolactone fibers under small and large strains. Combining experiments with a visco‐hyperelastic damage model, this work reveals and quantifies these fibers’ nonlinear behavior, including strain‐stiffening, viscoelasticity, and damage.

Cauchy Matrix Factorization for Tag-Based Social Image Retrieval

IEEE Access, 2019
User-provided tags associated with social images are essential information for social image retrieval. Unfortunately, these tags are often imperfect to describe the visual contents, which severely degrades the performance of image retrieval.

Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

Advanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Multi-objective Probabilistic fractional Programming Problem involving two parameters Cauchy Distribution

Mathematical Modelling and Analysis, 2019
The paper presents the solution methodology of a multi-objective probabilistic fractional programming problem, where the parameters of the right hand side constraints follow Cauchy distribution. The proposed mathematical model can not be solved directly.

Nonlocal Conduction in a Metawire

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
A 1D metawire composed of twisted copper wires is designed and realized. This metamaterial exhibits pronounced effects of nonlocal electric conduction according to Ohm's law. The current at one location not only depends on the electric field at that location but also on other locations.

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

Monogenic Gaussian distribution in closed form and the Gaussian fundamental solution

, 2009
In this paper we present a closed formula for the CK-extension of the Gaussian distribution in $\mathbb R^m$, and the monogenic version of the holomorphic function $\exp(z^2/2)/z$ which is a fundamental solution of the generalized Cauchy-Riemann ...

Full Wafer Scale Manufacturing of Directly Printed TiO2 Metalenses at Visible Wavelengths with Outstanding Focusing Efficiencies

Advanced Materials, EarlyView.
The highest experimentally determined focusing efficiency is reported here by using the direct imprinting of all‐inorganic TiO2 metalens arrays. Absolute efficiency greater than 80% and relative efficiency greater than 90% are achieved by optimization of all fabrication parameters controllable in the additive manufacturing process.
