Characterizations of summability methods derived by q-Cesàro matrix
Dera Natung Government College Research JournalThe present study mainly aims to introduce the absolute summability method derived from the transformation matrix obtained by the -Cesàro matrix and to establish the necessary and sufficient conditions for and where In addition, by ...

On a method for inverse theorems for (C,1) and gap (C,1) summability
International Journal of Mathematics and Mathematical Sciences, 1984 A simple method for proving several theorems of Tauberian and Mercerian type for (C,1) and gap (C,1) summability is presented.

FEBS Open Bio, EarlyView.A regulatory axis involving APE1, AUF1, and miR‐221 is proposed. Pri‐miR‐221 is processed by DROSHA and DICER to generate mature miR‐221, which targets p27Kip1 mRNA. APE1 and AUF1 compete for pre‐miR‐221 binding. Reduced APE1/AUF1 levels impair miR‐221 biogenesis, decrease p27Kip1 mRNA degradation, and promote cell cycle progression, chemoresistance ...

Convolution of summability methods [PDF]
Rendiconti del Circolo Matematico di Palermo, 1978 One of the purposes of the paper is to examine whether the convolutionA*B is in (X, Y) wheneverA andB are in (X, Y) denoting by (X, Y) the set of all infinite matrices operating on a sequence spaceX into another sequence spaceY. There are results relating to conullity, multiplicative property and characteristic numbers of the convolution of ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

TAUBERIAN THEOREM FOR GENERAL MATRIX SUMMABILITY METHOD
Ural Mathematical JournalIn this paper, we prove certain Littlewood–Tauberian theorems for general matrix summability method by imposing the Tauberian conditions such as slow oscillation of usual as well as matrix generated sequence, and the De la Vallée Poussin means of real ...

FEBS Open Bio, EarlyView.Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

A study of some new absolute summability methods
International Journal of Mathematics and Mathematical Sciences, 1997 In this note we introduce a new method of absolute summability. A general theorem is given. Several results are also deduced.

FEBS Open Bio, EarlyView.ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

FEBS Open Bio, EarlyView.Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.
