On the Menger and almost Menger properties in locales
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 almost set-Menger spaces in bitopological context
<abstract><p>In this paper, we define the $ ij $-almost-set Menger ($ ij $-ASM) property in bitopological spaces. We put up some equivalences of $ ij $-almost-set Menger bitopological spaces and investigate the behaviours of such spaces under some different types of mappings.

By employing g-open sets, we present the concept of almost GOMenger space in this article. After that, the nature of almost GO-Menger space is compared to GO-Menger space, and some fundamental topological aspects of such spaces are examined. Additionally,

Almost strongly star-Menger and related properties
In this paper we introduce the almost strongly star-Menger property and we provide some results and relationships with another known properties in literature.

Some remarks on almost Menger spaces and weakly Menger spaces
A space X is almost Menger (weakly Menger) if for each sequence (Un : n ? N) of open covers of X there exists a sequence (Vn : n ? N) such that for every n ? N, Vn is a finite subset of Un and ?n?N ?{V : V ? Vn} = X (respectively, ?n?N ?{V : V ? Vn} = X).

Comparing Two Novel LiDAR-Based Indices for Quantifying Forest Structural Complexity. [PDF]
This study compares two LiDAR‐derived forest structural complexity indices: the fractal‐based box dimension (Db$$ {D}_b $$) and the entropy‐based canopy entropy (CE$$ CE $$). Analysis of 170 plots revealed a strong linear correlation (r = 0.823) between Db$$ {D}_b $$ and CE$$ CE $$, but computation was much slower.

Weakly strongly star-Menger spaces
A space $X$ is called weakly strongly star-Menger space if for each sequence ($\mathcal{U}_{n} : n \in \omega$) of open covers of $X,$ there is a sequence $(F_n : n\in\omega)$ of finite subsets of $X$ such that $\overline{\bigcup_{n\in\omega} St(F_n ...

Additively manufactured porous NiTi alloys hold unprecedented promise in metallic implants due to their low elastic modulus and superelastic behavior. Such porous structures are usually topologically ordered and designed with periodically-repeating unit ...

A Meir-Keeler type fixed point theorem for a family of mappings is proved in Menger probabilistic metric space (Menger PM-space). We establish that completeness of the space is equivalent to fixed point property for a larger class of mappings that ...

Selection principles and covering properties in bitopological spaces
Our main focus in this paper is to introduce and study various selection principles in bitopological spaces. In particular, Menger type, and Hurewicz type covering properties like: Almost p-Menger, star p-Menger, strongly star p-Menger, weakly p-Hurewicz,
