Matrix Transformations of Generalized Almost Convergent Double Sequences

open access: yesAxioms
In this paper, we study matrix transformations on spaces of generalized almost convergent double sequences with powers. Extending classical results of Lorentz, Maddox, and Nanda, we characterize several classes of infinite matrices that map between ...

A Guide to Localized Frames and Applications to Galerkin-like Representations of Operators

open access: yes, 2016
This chapter offers a detailed survey on intrinsically localized frames and the corresponding matrix representation of operators. We re-investigate the properties of localized frames and the associated Banach spaces in full detail.

Level sets estimation and Vorob'ev expectation of random compact sets [PDF]

open access: yes, 2011
The issue of a "mean shape" of a random set $X$ often arises, in particular in image analysis and pattern detection. There is no canonical definition but one possible approach is the so-called Vorob'ev expectation $\E_V(X)$, which is closely linked to ...

On the paranormed binomial sequence spaces

open access: yesUniversal Journal of Mathematics and Applications, 2018
In this paper the sequence spaces $b_0^{r,s}(p)$, $b_c^{r,s}(p)$, $b_{\infty}^{r,s}(p)$ and $b^{r,s}(p)$ which are the generalization of the classical Maddox's paranormed sequence spaces have been introduced and proved that the spaces $b_0^{r,s}(p ...

Domain of the Cesàro mean of order α in Maddox’s space ℓ(p)

open access: yesPublications de l'Institut Math?matique (Belgrade), 2023
The sequence space ?(p) was defined by I. J. Maddox, Spaces of strongly summable sequences, Quart. J. Math. Oxford (2), 18 (1967), 345-355. Here, we introduce the paranormed Cesaro sequence space ?(C?, p) of order ?, of non-absolute type as the domain

Theorising the Conjuncture Through Gaza: Urban Destruction and the Intensification of Authoritarian Neoliberalism

open access: yesAntipode, Volume 58, Issue 3, May 2026.
ABSTRACT This paper deploys a Gramscian theorisation of the conjuncture to argue that the contemporary global political economy is becoming constituted through the destruction of Gaza. It contends that Gaza's destruction illuminates the current conjuncture as an intensification of earlier authoritarian neoliberal tendencies.

Color bimodality: Implications for galaxy evolution [PDF]

open access: yes, 2004
We use a sample of 69726 galaxies from the SDSS to study the variation of the bimodal color-magnitude (CM) distribution with environment.

A Climatology of Mesoscale Convective System Hazards in the United States and Their Representation in a Convection‐Permitting Model

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Mesoscale convective systems (MCSs) are large, organized convective storms that frequently produce flash floods and other severe hazards such as damaging winds, hail, and tornadoes. Developing an observationally based MCS hazard climatology is important for establishing a baseline to evaluate the representation of these events in numerical ...

Unraveling genetic diversity and loci conferring leaf blast resistance in East and Southern African rice germplasm

open access: yesCrop Science, Volume 66, Issue 2, March/April 2026.
Abstract Rice blast remains a major disease, causing severe yield losses in rice‐producing regions and posing a threat to global food security. Understanding genetic variation within germplasms is crucial for identifying locally adapted genotypes with beneficial alleles for improving resistance to this disease.

SOME NEW PARANORMED DIFFERENCE SEQUENCE SPACES DERIVED BY FIBONACCI NUMBERS [PDF]

open access: yes, 2013
In this study, we define new paranormed sequence spaces derived by the sequences of Fibonacci numbers. Furthermore, we compute the ; and duals and obtain bases for these sequence spaces.
