A Class of Linear Positive Maps in Matrix Algebras [PDF]

open access: yesOpen Systems & Information Dynamics, 2003
A class of linear positive, trace preserving maps in Mn is given in terms of affine maps in ℝn2−1 which map the closed unit ball into itself.

Single‐cell DNA methylation profiling: Technologies, computation, and applications in precision oncology

open access: yesMolecular Oncology, EarlyView.
Single‐cell DNA methylation (scDNAme) profiling maps epimutational clonal evolution, revealing mechanisms of malignancy and therapeutic resistance across diverse cancer types. By providing a high‐resolution landscape of intratumoral heterogeneity, these technologies empower precise patient stratification, guide the development of enhanced ...

New Integrated and Differentiated Sequence Spaces $\int{b_{p}^{r,s}}$ and $d\,b_{p}^{r,s}$

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi
In this work, we construct new sequence spaces by combining the integrated and differentiated sequence spaces with the binomial matrix. Firstly, we provide information about basic matters such as sequence spaces and matrix domain. Subsequently we briefly

Duality in non-Hermitian random matrix theory

open access: yesNuclear Physics B
We consider 9 Gaussian matrix ensembles characterized by single symmetry among the 38-fold symmetry classification classes of non-Hermitian random matrices, and establish exact duality formulae of certain observables between them.

Quantifying and mapping land use changes and regulating ecosystem service potentials in a data-scarce peri-urban region in Kenya

open access: yesEcosystems and People, 2019
Recent scientific developments are advancing to link land use and land cover (LULC) change with ecosystem service (ES) potentials. Such links within peri-urban ecosystems are scanty due to methodological and expertise challenge, and data limitation.

Targeting transcription factors associated with hemoglobinopathies: Lessons from successful interventions and implications for cancer

open access: yesMolecular Oncology, EarlyView.
This review summarizes the transcription factors, repressive chromatin‐modifying complexes, and epigenetic mechanisms that control fetal hemoglobin repression. Notably, many regulators of γ‐globin silencing also function in transcriptional and epigenetic networks that drive cancer, highlighting opportunities to translate advances in hemoglobinopathy ...

CEACAM1 participation in breast cancer progression

open access: yesMolecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Compact Operators for Almost Conservative and Strongly Conservative Matrices

open access: yesAbstract and Applied Analysis, 2014
We obtain the necessary and sufficient conditions for an almost conservative matrix to define a compact operator. We also establish some necessary and sufficient (or only sufficient) conditions for operators to be compact for matrix classes (f,X), where ...

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

open access: yesMolecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Matrix Summability of Classes of Geometric Sequences

open access: yesRocky Mountain Journal of Mathematics, 1992
An infinite matrix \(A\) is called an \(X-Y\) matrix if \(u\in X\) implies \(Au\in Y\), where \((Au)_ n:=\sum_ k a_{nk}u_ k\). \textit{G. W. Fricke} and \textit{J. A. Fridy} [Can. J. Math. 39, 568-582 (1987; Zbl 0618.40003)] introduced the set \(G\) of complex number sequences that are dominated by some convergent geometric sequence, and gave ...
