$\sigma$-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,

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.

On the Menger and almost Menger properties in locales [PDF]
Applied General Topology, 2021 The Menger and the almost Menger properties are extended to locales. Regarding the former, the extension is conservative (meaning that a space is Menger if and only if it is Menger as a locale), and the latter is conservative for sober TD-spaces.

On maximal nowhere dense sublocales [PDF]
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.

Localic maps constructed from open and closed parts [PDF]
Categories and General Algebraic Structures with Applications, 2017 Assembling a localic map f:L→M from localic maps fi:Si→M, i∈J, defined on closed resp. open sublocales (J finite in the closed case) follows the same rules as in the classical case.

Notes on point-free real functions and sublocales [PDF]
, 2014 Using the technique of sublocales we present a survey of some known facts (with a few new ones added) on point-free real functions. The subjects treated are, e.g., images and preimages, semicontinuity, algebraic structure (point-free real arithmetics ...

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.

Hybrid Rule‐Based Solution for Phishing URL Detection Using Convolutional Neural Network
Wireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021 The phenomenon of phishing has now been a common threat, since many individuals and webpages have been observed to be attacked by phishers. The common purpose of phishing activities is to obtain user’s personal information for illegitimate usage. Considering the growing intensity of the issue, this study is aimed at developing a new hybrid rule‐based ...

Another proof of Banaschewski's surjection theorem [PDF]
Categories and General Algebraic Structures with Applications, 2019 We present a new proof of Banaschewski's theorem stating that the completion lift of a uniform surjection is a surjection. The new procedure allows to extend the fact (and, similarly, the related theorem on closed uniform sublocales of complete uniform ...

When spectra of lattices of $z$-ideals are Stone-Čech compactifications [PDF]
Mathematica Bohemica, 2017 Let $X$ be a completely regular Hausdorff space and, as usual, let $C(X)$ denote the ring of real-valued continuous functions on $X$. The lattice of $z$-ideals of $C(X)$ has been shown by Martínez and Zenk (2005) to be a frame.
