Slowly varying functions and asymptotic relations

open access: yesJournal of Mathematical Analysis and Applications, 1971
Abstract : A survey of basic properties of slowly varying functions is given. The notion of quasi monotone functions is introduced and it is shown that a quasi monotone slowly varying function can be represented as a quotient of two non decreasing functions.

Further research on complete moment convergence for moving average process of a class of random variables

open access: yesJournal of Inequalities and Applications, 2017
In this article, the complete moment convergence for the partial sum of moving average processes { X n = ∑ i = − ∞ ∞ a i Y i + n , n ≥ 1 } $\{X_{n}=\sum_{i=-\infty}^{\infty}a_{i}Y_{i+n},n\geq 1\}$ is established under some mild conditions, where { Y i , −

Multimodal intrinsic speckle-tracking (MIST) to extract images of rapidly-varying diffuse X-ray dark-field

open access: yesScientific Reports, 2023
Speckle-based phase-contrast X-ray imaging (SB-PCXI) can reconstruct high-resolution images of weakly-attenuating materials that would otherwise be indistinguishable in conventional attenuation-based X-ray imaging.

Asymptotic formulas for q-regularly varying solutions of half-linear q-difference equations

open access: yesElectronic Journal of Differential Equations, 2021
This article studies the asymptotic behavior of positive solutions of the q-difference half-linear equation $$ D_q(p(t)\Phi(D_q(x(t)))) + r(t)\Phi(x(qt))=0, \quad t \in q^{\mathbb{N}_0}:=\{q^n : n \in \mathbb{N}_0\}, $$ where \(q>1\), \(\Phi(x)=|x ...

Slowly Varying Solutions of Functional Differential Equations with Retarded and Advanced Arguments [PDF]

open access: yesgmj, 2007
Abstract Regularity, in the sense of Karamata, (with nonoscillation as a consequence) and the precise asymptotic behaviour of solutions of two functional differential equations are studied.

Consistency of the Least Squares Estimate of Textured Surface Parameters

open access: yesНаукові вісті Національного технічного університету України "Київський політехнічний інститут", 2017
Background. For sinusoidal observation model of textured surface, i.e. model where regression function is a two-parameter harmonic oscillation and noise is a homogeneous isotropic Gaussian random field on the plane with zero mean and covariance function ...

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

The Green`s function for an acoustic, half-space impedance problem Part II: Analysis of the slowly varying and the plane wave component [PDF]

open access: yes
We show that the acoustic Green`s function for a half-space impedance problem in arbitrary spatial dimension d can be written as a sum of two terms, each of which is the product of an exponential function with the eikonal in the argument and a slowly ...

SOME RESULTS ON THE CONCEPT OF {𝑎𝑚,𝑛,𝑖,𝑗 } – STOCHASTIC DOMINATION FOR DOUBLE ARRAYS OF RANDOM VARIABLES

open access: yesTạp chí Khoa học
In this paper, we prove some results on the concept of {𝑎𝑚,𝑛,𝑖,𝑗}- stochastic domination for double arrays of random variables, where {𝑘𝑚, 𝑚 ≥ 1} and {𝑙𝑛, 𝑛 ≥ 1 } are two sequences of positive integers and {𝑎𝑚,𝑛,𝑖,𝑗; 1 ≤ 𝑖 ≤ 𝑘𝑚, 1 ≤ 𝑗 ≤ 𝑙𝑛, 𝑚, 𝑛 ≥ 1}
