Complex s-Plane Modeling and 2D Characterization of the Stochastic Scattering Loss in Symmetric Dielectric Slab Waveguides Exhibiting Ergodic Surface-Roughness With an Exponential Autocorrelation Function

open access: yesIEEE Access, 2021
The symmetric dielectric slab waveguide serves as an important canonical structure for the high-speed high-bandwidth optical and opto-electronic silicon-on-insulator interconnects.

Stationary solutions for the Cahn-Hilliard equation [PDF]

open access: yes, 1998
We study the Cahn-Hilliard equation in a bounded domain without any symmetry assumptions. We assume that the mean curvature of the boundary has a nongenerate critical point.

A New Class of 2q-Point Nonstationary Subdivision Schemes and Their Applications

open access: yesMathematics, 2019
The main objective of this study is to introduce a new class of 2 q -point approximating nonstationary subdivision schemes (ANSSs) by applying Lagrange-like interpolant. The theory of asymptotic equivalence is applied to find the continuity of the

Information Theory for Non-Stationary Processes with Stationary Increments [PDF]

open access: yesEntropy, 2019
We describe how to analyze the wide class of non-stationary processes with stationary centered increments using Shannon information theory. To do so, we use a practical viewpoint and define ersatz quantities from time-averaged probability distributions.

Differential Protein Expression in Exponential and Stationary Growth Phases of Mycobacterium avium subsp. hominissuis 104

open access: yesMolecules, 2021
Mycobacterium avium complex (MAC) is the most common non-tuberculous mycobacterium (NTM) and causes different types of pulmonary diseases. While genomic and transcriptomic analysis of Mycobacterium avium 104 (M.

Non-stationary log-periodogram regression [PDF]

open access: yes, 1998
We study asymptotic properties of the log-periodogram semiparametric estimate of the memory parameter d for non-stationary (d>=1/2) time series with Gaussian increments, extending the results of Robinson (1995) for stationary and invertible Gaussian ...

Characteristics of edge temperature ring oscillation during the stationary improved confinement mode in EAST

open access: yesNuclear Fusion, 2023
The I-mode is a natural edge localized mode (ELM)-free regime with H-mode-like improved energy confinement and L-mode-like particle confinement, making it an attractive scenario for future tokamak-based fusion reactors.

A Note on Extension of Fuzzy Metric Spaces

open access: yesMathematics, 2023
In this note, we prove that for two compatible fuzzy metrics MH and MK on H and K, respectively, there exists a fuzzy metric M on H⋃K such that M|H=MH and M|K=MK under the conditions that t-norm ∗ is positive and fuzzy metrics MH,MK are strong, or t-norm

On Stationary and Non-Stationary M-Band Framelet Packets

open access: yesJournal of Mathematical Extension, 2015
This paper deals with a construction of both stationary and non-stationary M-band tight framelet packets in L 2 (R) using extension principles. The approach here is different from the method described by Shah and Debnath in [ Explicit construction ...
