Characterizations of a Banach Space through the Strong Lacunary and the Lacunary Statistical Summabilities

Mathematics, 2020
In this manuscript we characterize the completeness of a normed space through the strong lacunary ( N θ ) and lacunary statistical convergence ( S θ ) of series. A new characterization of weakly unconditionally Cauchy series through N θ

Statistical Convergence of Double Sequences of Order

Journal of Function Spaces and Applications, 2013
We intend to make a new approach and introduce the concepts of statistical convergence of order and strongly -Cesàro summability of order for double sequences of complex or real numbers. Also, some relations between the statistical convergence of order

On the $\Delta _{{\Lambda ^2}}^f$-Statistical Convergence on Product Time Scale

Universal Journal of Mathematics and Applications, 2020
In this paper, we first define a new density of a $\Delta $-measurable subset of a product time scale ${\Lambda ^2}$ with respect to an unbounded modulus function.

Weighted modulus Sθ-convergence of order α in probability

Arab Journal of Mathematical Sciences, 2017
Let θ={kr}r∈N∪{0} be a lacunary sequence, ϕ be a modulus function and {tn}n∈N be a sequence of real numbers such that tn>δ,∀n∈N (where δ is a fixed positive real number) and Tn=t1+t2+⋯+tn (where n∈N and T0=0).

Generalized Lacunary Statistical Difference Sequence Spaces of Fractional Order

International Journal of Mathematics and Mathematical Sciences, 2015
We generalize the lacunary statistical convergence by introducing the generalized difference operator Δνα of fractional order, where α is a proper fraction and ν=(νk) is any fixed sequence of nonzero real or complex numbers.

Strong Convergence on Iterative Methods of Cesàro Means for Nonexpansive Mapping in Banach Space

Abstract and Applied Analysis, 2014
Two new iterations with Cesàro's means for nonexpansive mappings are proposed and the strong convergence is obtained as n→∞. Our main results extend and improve the corresponding results of Xu (2004), Song and Chen (2007), and Yao et al. (2009).

Penalized Convex Estimation in Dynamic Location Models

Journal of Time Series Analysis, EarlyView.
ABSTRACT This paper studies L1$$ {L}^1 $$‐penalized estimation for location models yt=mt+ϵt$$ {y}_t={m}_t+{\epsilon}_t $$, where mt$$ {m}_t $$ is defined by a possibly non‐Markovian recursion and ϵt$$ {\epsilon}_t $$ is a martingale difference sequence with possibly time‐varying conditional variance.

Immunoprofiling, sex‐ and age‐related determinants of treatment response in paediatric, adolescent and young adult Hodgkin lymphoma

British Journal of Haematology, Volume 208, Issue 5, Page 1617-1630, May 2026.
Multimodal integration of sex‐ and age‐related immune‐gene signatures with baseline tumor burden (TMTV1) improves prediction of treatment response in adolescents and young adults with classical Hodgkin lymphoma. Summary The study investigates how sex and age influence treatment response in paediatric, adolescent and young adult (AYA) classical Hodgkin ...

Natural measures and statistical properties of non‐statistical maps with multiple neutral fixed points

Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract We show that a large class of infinite measure preserving dynamical systems that do not admit physical measures nevertheless exhibit strong statistical properties. In particular, we give sufficient conditions for existence of a distinguished natural measure ν$ \nu$ such that the pushforwards of any absolutely continuous probability measure ...

Damping Modification Factors for Pile–Induced Filtering Effect

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 4, Page 907-925, 10 April 2026.
ABSTRACT Period–dependent Damping Modification Factors are usually applied to the 5%–damped pseudo–acceleration response spectrum at free field conditions to derive the seismic demand for structures with damping ratio other than 5%. Likewise, the response spectrum at the foundation level of pile–supported structures may differ from the free field ...
