On the invariant mean and statistical convergence
Applied Mathematics Letters, 2009 The authors introduce two kinds of summability methods, \(\sigma\)-statistical summability and statistical \(\sigma\)-summability, by using the concepts of invariant means, and statistical convergence. A sequence \((x_{k})\) is said to be \(\sigma\)-statistically convergent to \(L\) if for every \( \varepsilon> 0\) \[ \lim_{p\rightarrow\infty}\frac{1 ...

Some Spaces of Double Sequences Obtained through Invariant Mean and Related Concepts
Abstract and Applied Analysis, 2013 We introduce some double sequences spaces involving the notions of invariant mean (or -mean) and -convergence for double sequences while the idea of -convergence for double sequences was introduced by Çakan et al.

A new perspective on the spatio-temporal variability of soil moisture: temporal dynamics versus time-invariant contributions [PDF]
Hydrology and Earth System Sciences, 2012 Knowledge about the spatio-temporal variability of soil moisture is essential to understand and predict processes in climate science and hydrology. A significant body of literature exists on the characterization of the spatial variability and the rank ...

Invariant Tests for Means with Covariates
The Annals of Statistics, 1980 We consider the problem of testing a hypothesis about the means of a subset of the components of a multivariate normal distribution with unknown covariance matrix, when the means of a second subset (the covariates) are known. Because of the possible correlation between the two subsets, information provided by the second subset can be useful for ...

Thickness in topological transformation semigroups
International Journal of Mathematics and Mathematical Sciences, 1993 This article deals with thickness in topological transformation semigroups (τ-semigroups). Thickness is used to establish conditions guaranteeing an invariant mean on a function space defined on a τ-semigroup if there exists an invariant mean on its ...

Invariant Means And Multiplicative Matrices
Communications, Faculty Of Science, University of Ankara Series A1Mathematics and Statistics, 1980 Schaefer [7] has introduced the concept of a conservative and ct regular matrices and obtains necessary and suHicient conditions to characterize these classes of matrices.In the present paper authors have defîned (c, VCT)|3-matrices and (cOp,VQ)p and ohtain necessary and sufficient conditions to characterize them.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Black-Box Optimization Using Geodesics in Statistical Manifolds
Entropy, 2015 Information geometric optimization (IGO) is a general framework for stochastic optimization problems aiming at limiting the influence of arbitrary parametrization choices: the initial problem is transformed into the optimization of a smooth function on a

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Some results of Heron mean and Young’s inequalities
Journal of Inequalities and Applications, 2018 In this paper, we will show some improvements of Heron mean and the refinements of Young’s inequalities for operators and matrices with a different method based on others’ results.
