An Application of δ-Quasi Monotone Sequence

International Journal of Analysis and Applications, 2017
In this paper, a known theorem dealing with $|A,p_{n}|_{k}$ summability method of infinite series has been generalized to $| A,p_{n};\delta|_{k}$ summability method. Also, some results have been obtained.

On the Absolute Summability (A) of Infinite Series [PDF]

Proceedings of the Edinburgh Mathematical Society, 1932
§1. A serieshas been defined by J. M. Whittaker to be absolutely summable (A), ifis convergent in (0 ≤ x < 1) and f (x) is of bounded variation in (0, 1), i.e.for all subdivisions 0 = x0 < x1 < x2 < . … < xm < 1.

Real‐World Safety and Effectiveness of JAK Inhibitors in Systemic Sclerosis: A Propensity‐Matched Study from the EUSTAR Cohort

Arthritis Care &Research, Accepted Article.
Objective JAK inhibitors (JAKis) have shown promising effects in early‐phase studies of SSc. We aimed to assess the safety and explore effectiveness of JAKis compared to conventional immunosuppressants in SSc. Methods A longitudinal retrospective study of the EUSTAR cohort was performed.

Adaptive Observer for Coupled Wave PDE and Infinite ODE With Sampled Data and Unknown Input: Application to Brain Hemodynamics Estimation

International Journal of Adaptive Control and Signal Processing, EarlyView.
This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.

Localization and summability of multiple Hermite series

International Journal of Mathematics and Mathematical Sciences, 1997
The multiple Hermite series in Rn are investigated by the Riesz summability method of order α>(n−1)/2. More precisely, localization theorems for some classes of functions are proved and sharp sufficient conditions are given.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Strong Summability of Fourier Transforms at Lebesgue Points and Wiener Amalgam Spaces

Journal of Function Spaces, 2015
We characterize the set of functions for which strong summability holds at each Lebesgue point. More exactly, if f is in the Wiener amalgam space W(L1,lq)(R) and f is almost everywhere locally bounded, or f∈W(Lp,lq)(R ...

The absolute summability (A) of ultraspherical series [PDF]

Annali di Matematica Pura ed Applicata, 1962
This paper is devoted to the discussion of |A| summability of ultraspherical series on a sphere. The first theorem also gives a new result forLaplace series in case λ=1/2.
