Field reduction and linear sets in finite geometry [PDF]

open access: yes, 2014
Based on the simple and well understood concept of subfields in a finite field, the technique called `field reduction' has proved to be a very useful and powerful tool in finite geometry. In this paper we elaborate on this technique.

Through-the-Wall Microwave Imaging: Forward and Inverse Scattering Modeling

open access: yesSensors, 2020
The imaging of dielectric targets hidden behind a wall is addressed in this paper. An analytical solver for a fast and accurate computation of the forward scattered field by the targets is proposed, which takes into account all the interactions of the ...

Vietoris hyperspaces over scattered Priestley spaces

open access: yesIsrael Journal of Mathematics, 2022
We study Vietoris hyperspaces of closed and closed final sets of Priestley spaces. We are particularly interested in Skula topologies. A topological space is \emph{Skula} if its topology is generated by differences of open sets of another topology. A compact Skula space is scattered and moreover has a natural well-founded ordering compatible with the ...

Scattered $P$-spaces of weight $\omega_1$

open access: yesTopology and its Applications, 2022
We examine dimensional types of scattered $P$-spaces of weight $\omega_1$. Such spaces can be embedded into $\omega_2$. There are established similarities between dimensional types of scattered separable metric spaces and dimensional types of $P$-spaces of weight $\omega_1$ with Cantor--Bendixson rank less than $\omega_1$.

Fibroma of the Peroneus Longus Tendon Sheath in a Child: A Case Report

open access: yesJournal of Orthopaedic Surgery, 2013
Tendon sheath fibromas are rare, benign soft-tissue tumours and usually involve tendons of the upper extremities, particularly the fingers. The most common presentation is a painless, slow-growing swelling.

On δ-Scattered Space

open access: yesEarthline Journal of Mathematical Sciences, 2022
The object of the present paper is to introduce the concept of δ-scattered spaces as a natural generalization of the concept of scattered spaces. We prove that the concept of δ-scatteredness of the space coincides with scatteredness. It is noted that scattered need not be δ-scattered in general, also I-space are comparable with δ-scattered space.

Constructions of thin-tall Boolean spaces [PDF]

open access: yes, 2003
This is an expository paper about constructions of locally compact, Hausdorff, scattered spaces whose Cantor-Bendixson height has cardinality greater than their Cantor-Bendixson ...

The role of neighborhood morphology in enhancing thermal comfort and resident’s satisfaction

open access: yesEnergy Reports, 2022
The unilateral development of built environments in cities leads to imbalances in climatic conditions and micro-climates, followed by indicators such as thermal comfort. Researchers identified the effect of urban morphology’s geometry, shape, orientation,

Espaces multiples : penser la pornographie depuis ses lieux de production

open access: yesBrésil(s), 2013
This essay intends to discuss the multiple meanings of the areas and places where porn movies are produced in the city of São Paulo and the statements regarding social markers of difference incorporated in them.

Scattered compactifications and the orderability of scattered spaces. II [PDF]

open access: yesProceedings of the American Mathematical Society, 1981
A space is suborderable if it is embeddable in a (totally) orderable space. It is shown that a suborderable scattered space is orderable and admits an orderable scattered compactification.
