Representation and Weak Convergence of Stochastic Integrals with Fractional Integrator Processes [PDF]

open access: yes
This paper considers the asymptotic distribution of the covariance of a nonstationary fractionally integrated process with the stationary increments of another such process - possibly, itself.

On Equivalents of the Riemann Hypothesis Connected to the Approximation Properties of the Zeta Function

open access: yesAxioms
The famous Riemann hypothesis (RH) asserts that all non-trivial zeros of the Riemann zeta function ζ(s) (zeros different from s=−2m, m∈N) lie on the critical line σ=1/2.

Weak Convergence of Certain Vectorvalued Measures

open access: yesThe Annals of Probability, 1974
There are two kinds of vectorvalued measures which are involved in the theory of weakly stationary processes: orthogonal (Hilbert space valued) and multiplicative (projection-valued) measures. For both classes we show that weak convergence is equivalent with the convergence of integrals over bounded continuous functions.

Cerebrospinal Fluid Over Plasma Links Analytes to Cognitive Decline in Older Adults at Risk for Alzheimer's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To identify inflammatory analytes in cerebrospinal fluid (CSF) and plasma associated with cognitive decline in cognitively normal (CN) older adults at risk for Alzheimer's disease (AD). Methods In a longitudinal study of 118 CN older adults (65–80 years, 54% APOE ε4, 26% preclinical AD), 1331 CSF and 1501 plasma analytes were ...

Discordance Between Systemic Lupus Erythematosus Disease Activity Index Domain Weights and Their Association With Organ Damage Accrual

open access: yesArthritis Care &Research, EarlyView.
Objective Studies of damage accrual in patients with systemic lupus erythematosus (SLE) show associations with disease activity measured by the SLE Disease Activity Index 2000 (SLEDAI‐2K), but these associations are imperfect. SLEDAI scores are powerfully influenced by weightings (1–8) assigned to each domain.

The Approximation of Analytic Functions Using Shifts of the Lerch Zeta-Function in Short Intervals

open access: yesAxioms
In this paper, we obtain approximation theorems of classes of analytic functions by shifts L(λ,α,s+iτ) of the Lerch zeta-function for τ∈[T,T+H] where H∈[T27/82,T1/2]. The cases of all parameters, λ,α∈(0,1], are considered.

Extending Service Beyond Active Duty: Generalizability of Rheumatoid Arthritis Research Conducted Among U.S. Veterans

open access: yesArthritis Care &Research, Accepted Article.
Biomedical research involving United States Veterans continues to advance healthcare beyond the Veterans Health Administration. This is particularly true in rheumatoid arthritis (RA), where Veteran‐centric research has uncovered novel insights into pathogenesis, risk factors, and disease manifestations, informing clinical care and research across both ...

Joint Approximation of Analytic Functions by Shifts of Hurwitz Zeta-Functions in Short Intervals

open access: yesAxioms
For j=1,…,r, αj∈(0,1) are such that the set {log(m+αj):m∈N0,j=1,…,r} is linearly independent over Q. In the paper, we consider simultaneous approximation of a tuple of analytic functions by shifts (ζ(s+iτ,α1),…,ζ(s+iτ,αr)) of the Hurwitz zeta-functions ...

Measurement characteristics and convergent validity of temporally modulated gap-overlap task versions: Evidence from an eye-tracking study in adolescents [PDF]

open access: yesSpecijalna Edukacija i Rehabilitacija
Although the gap-overlap paradigm is widely used in eye-tracking research to investigate visual attention disengagement, methodological heterogeneity limits comparability across studies. Aim.
