Related fixed point theorems on two complete and compact metric spaces
International Journal of Mathematics and Mathematical Sciences, 1998 A new related fixed point theorem on two complete metric spaces is obtained. A generalization is given for two compact metric spaces.

The contraction principle for mappings on a metric space with a graph
, 2007 We give some generalizations of the Banach Contraction Principle to mappings on a metric space endowed with a graph. This extends and subsumes many recent results of other authors which were obtained for mappings on a partially ordered metric space.

Molecular Oncology, EarlyView.The complex mode of action of the topoisomerase II inhibitor etoposide in triggering apoptosis involves several mechanisms: overexpression of the mitochondrial protein VDAC1, leading to its oligomerization and formation of a large channel that mediates the release of pro‐apoptotic protein; and overexpression of the apoptosis regulators p53, Bax, and ...

The metric of visual space [PDF]
Perception & Psychophysics, 1985 The geometric properties of visual space in the horizontal plane were measured by four different procedures. Five observers were asked to judge distances, angles, and areas defined by pairs and triplets of stakes, using magnitude estimation, category estimation, mapping, and perceptual matching.

Classification of Finite Subspaces of Metric Space Instead of Constraints on Metrics [PDF]
arXiv, 1999 A new method of metric space investigation, based on classification of its finite subspaces, is suggested. It admits to derive information on metric space properties which is encoded in metric. The method describes geometry in terms of only metric. It admits to remove constraints imposed usually on metric (the triangle axiom and nonnegativity of the ...

Molecular Oncology, EarlyView.Epithelial–mesenchymal transition (EMT) and tumor‐infiltrating lymphocytes (TILs) are associated with early breast cancer response to neoadjuvant chemotherapy (NAC). This study evaluated EMT and TIL shifts, with immunofluorescence and RNA sequencing, at diagnosis and in residual tumors as potential biomarkers associated with treatment response.

Molecular and functional profiling unravels targetable vulnerabilities in colorectal cancer
Molecular Oncology, EarlyView.We used whole exome and RNA‐sequencing to profile divergent genomic and transcriptomic landscapes of microsatellite stable (MSS) and microsatellite instable (MSI) colorectal cancer. Alterations were classified using a computational score for integrative cancer variant annotation and prioritization.

Separability of Metric Spaces [PDF]
Transactions of the American Mathematical Society, 1970 A topological space S is separable means that some countable subset of S is dense in S. A subset T of a topological space is separable means that T has a countable subset which is dense in T. In view of the importance of this property, it is natural to inquire about conditions under which a space is separable.

Molecular Oncology, EarlyView.Cancer stem cells are associated with aggressive disease, but a deep characterization of such markers is lacking in endometrial cancer. This study uses imaging mass cytometry to explore putative cancer stem cell markers in endometrial tumors and corresponding organoid models.
