J Healthc Eng, 2022 Radiology is a broad subject that needs more knowledge and understanding of medical science to identify tumors accurately. The need for a tumor detection program, thus, overcomes the lack of qualified radiologists. Using magnetic resonance imaging, biomedical image processing makes it easier to detect and locate brain tumors.

Axiom $T_D$ and the Simmons sublocale theorem [PDF]
Commentationes Mathematicae Universitatis Carolinae, 2020 Summary: More precisely, we are analyzing some of H. Simmons, S. B. Niefield and K. I. Rosenthal results concerning sublocales induced by subspaces. \textit{H. Simmons} [Proc. Edinb. Math. Soc., II. Ser. 21, 41--48 (1978; Zbl 0396.54014); Colloq. Math. 43, 23--39 (1980; Zbl 0459.54024)] was concerned with the question when the coframe of sublocales is ...

Journal of Pure and Applied Algebra, 2002 The lattice of sublocales of a locale, unlike the lattice of subspaces of a space, is not in general a Boolean algebra. It is not even a frame; but it is the dual of a frame, and so may be identified with the lattice of closed sublocales of another locale, called the dissolution of the original locale.

On maximal nowhere dense sublocales
Applied General TopologyThe aim of this paper is to study some variants of nowhere dense sublocales called maximal nowhere dense and homogeneous maximal nowhere dense sublocales. These concepts were initially introduced by Veksler in classical topology.

A little more on ideals associated with sublocales [PDF]
Categories and General Algebraic Structures with ApplicationsAs usual, let $\mathcal RL$ denote the ring of real-valued continuous functions on a completely regular frame $L$. Let $\beta L$ and $\lambda L$ denote the Stone-\v{C}ech compactification of $L$ and the Lindel\"of coreflection of $L$, respectively ...

Bulletin of the Belgian Mathematical Society - Simon Stevin, 2010 As \textit{P.\,T.\,Johnstone} stressed in [``The art of pointless thinking: a student's guide to the category of locales'', Res. Expo. Math. 18, 85--107 (1991; Zbl 0745.18003)], ``one of the most important reasons for studying the category of locales as a substitute for (and in many ways an improvement on) the category of topological spaces'' (which ...

More on locales in which every open sublocale is z-embedded
Topology and Its Applications, 2016 Locales in which every open sublocale is \(z\)-embedded are called \textit{Oz-locales}. They were introduced by \textit{B. Banaschewski} and \textit{C. Gilmour} [``Oz revisited'', in: H. Herrlich (ed.) and H.-E. Porst (ed.), Proceedings of the conference on categorical methods in algebra and topology. Bremen: Universität Bremen.

$\sigma$-locales in Formal Topology [PDF]
Logical Methods in Computer Science, 2022 A $\sigma$-frame is a poset with countable joins and finite meets in which binary meets distribute over countable joins. The aim of this paper is to show that $\sigma$-frames, actually $\sigma$-locales, can be seen as a branch of Formal Topology, that is,

Products on Maximal Compact Frames
Ratio Mathematica, 2023 In topological spaces, many topological properties such as separation properties, paracompactness etc. are preserved under the act of taking product of topological spaces.
