On |A|k summability factors of infinite series; pp. 201–206 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2010
In an earlier paper (Rhoades, B. E. and Savaş, E. Some necessary conditions for absolute matrix summability factors. Indian J. Pure Appl. Math., 2002, 33(7), 1003–1009) the authors obtained necessary conditions for the series ∑ an to be absolutely ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

On two new types of statistical convergence and a summability method - doi: 10.4025/actascitechnol.v36i1.16206

open access: yesActa Scientiarum: Technology, 2014
In this paper, we introduce and investigate relationship among I-statistically Delta_r^s -convergent, I-lambda-statistically Delta_r^s-convergent and I-[V, lambda, Delta_r^s]-summable sequences respectively over normed linear ...

Wandering intervals and absolutely continuous invariant probability measures of interval maps [PDF]

open access: yes, 2009
For piecewise $C^1$ interval maps possibly containing critical points and discontinuities with negative Schwarzian derivative, under two summability conditions on the growth of the derivative and recurrence along critical orbits, we prove the ...

Summability-Preserving Functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1961
PROOF. Every subsequence of { Xn} converges, so that every subsequence of {f(xn) } is A-summable, by hypothesis. By [I], applied to complex sequences, {f(xn) } is actually convergent. (For the proof of [I] can be modified to apply to complex sequences.

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

A strong version of Poisson summation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
We establish a generalized version of the classical Poisson summation formula. This formula incorporates a special feature called “compression”, whereby, at the same time that the formula equates a series to its Fourier dual, the compressive feature ...

Spectral triples and finite summability on Cuntz-Krieger algebras [PDF]

open access: yes, 2015
We produce a variety of odd bounded Fredholm modules and odd spectral triples on Cuntz-Krieger algebras by means of realizing these algebras as "the algebra of functions on a non-commutative space" coming from a sub shift of finite type. We show that any
