A New Outlook for Almost Convergent Sequence Spaces

open access: yesCumhuriyet Science Journal, 2018
Thepoint standing out in the present paper is the sequence spaces , and producedby the domain of the infinite matrix ,which is defined in the previous study of Candan [2], where the spaces , and ,respectively, are as presented by G.G.

Transformations of normal form games by preplay offers for payments among players [PDF]

open access: yes, 2012
We consider transformations of normal form games by binding preplay offers of players for payments of utility to other players conditional on them playing designated in the offers strategies.

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 ...

Compactness of quadruple band matrix operator and geometric properties

open access: yesAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2022
In this work, we characterize the class of compact matrix operators from c0(Q), c(Q) and l∞(Q) into c0, c and l∞, respectively, with the notion of the Hausdorff measure of noncompactness.

Perturbation analysis of a matrix differential equation $\dot x=ABx$

open access: yes, 2018
Two complex matrix pairs $(A,B)$ and $(A',B')$ are contragrediently equivalent if there are nonsingular $S$ and $R$ such that $(A',B')=(S^{-1}AR,R^{-1}BS)$. M.I. Garc\'{\i}a-Planas and V.V.

Potential therapeutic targeting of BKCa channels in glioblastoma treatment

open access: yesMolecular Oncology, EarlyView.
This review summarizes current insights into the role of BKCa and mitoBKCa channels in glioblastoma biology, their potential classification as oncochannels, and the emerging pharmacological strategies targeting these channels, emphasizing the translational challenges in developing BKCa‐directed therapies for glioblastoma treatment.

Forecasts of non-Gaussian parameter spaces using Box-Cox transformations

open access: yes, 2011
Forecasts of statistical constraints on model parameters using the Fisher matrix abound in many fields of astrophysics. The Fisher matrix formalism involves the assumption of Gaussianity in parameter space and hence fails to predict complex features of ...

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

open access: yesMolecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

Fixed Points of Two-Sided Fractional Matrix Transformations

open access: yesFixed Point Theory and Applications, 2007
Let and be complex matrices, and consider the densely defined map on matrices. Its fixed points form a graph, which is generically (in terms of ) nonempty, and is generically the Johnson graph ; in the nongeneric case, either it is a retract of the

Covariance, correlation matrix and the multi-scale community structure of networks

open access: yes, 2010
Empirical studies show that real world networks often exhibit multiple scales of topological descriptions. However, it is still an open problem how to identify the intrinsic multiple scales of networks.
