Weakly hereditary regular closure operators
, 1993 We present characterizations of subcategories inducing weakly hereditary regular closure operators. These characterizations are applicable, in particular, to the category Top of topological spaces and continuous maps and to Abelian categories.

Quasi-uniform structures determined by closure operators
, 2021 We demonstrate a one-to-one correspondence between idempotent closure operators and the so-called saturated quasi-uniform structures on a category C. Not only this result allows to obtain a categorical counterpart P of the Császár-Pervin quasi-uniformity

On boundary value problems for essentially loaded parabolic equations in bounded domains
Қарағанды университетінің хабаршысы. Математика сериясы, 2020 In the paper we study issues of a strong solution for "essentially" loaded differential equations of the parabolic type in bounded domains. Features of the problems under consideration: for example, in the L 2( Q ) space the corresponding differential ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers
Molecular Oncology, EarlyView.This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

On the closure of absolutely norm attaining operators
, 2022 Let H-1 and H-2 be complex Hilbert spaces and T : H-1 -> H-2 be a bounded linear operator. We say T is norm attaining if there exists x is an element of H-1 with parallel to x parallel to = 1 such that parallel to Tx parallel to = parallel to T parallel ...

Linear Programming Problems in Network Coding and Closure Operators via Partitions
Selecciones Matemáticas, 2019 A network is an acyclic directed graph in which there are sources that have some messages and want to transmit to receivers through the combination of messages in intermediate nodes.

Molecular 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.

Some order dualities in logic, games and choices [PDF]
We first present the concept of duality appearing in order theory, i.e. the notions of dual isomorphism and of Galois connection. Then, we describe two fundamental dualities, the duality extension/intention associated with a binary relation between two ...
