A new class of regular black hole solutions with quasi-localized sources of matter in (2 + 1) dimensions [PDF]

open access: yesPhysics Letters B, 2022
In this paper, we investigate a new class of regular black hole solutions in (2 + 1)-dimensions by introducing a generalization of the quasi-localized matter model proposed by Estrada and Ortiz. Initially, we try to physically interpret the matter source

Resource allocation for multi‐IRS‐aided D2D communication underlying cellular networks

open access: yesIET Communications, Volume 16, Issue 13, Page 1628-1641, August 2022., 2022
Abstract This paper investigates the resource allocation design in device‐to‐device (D2D) communication underlying cellular networks, which is assisted by multiple intelligent reflecting surfaces (IRSs) deployed at the cell boundary to enhance desired signals and mitigate interference between D2D pairs and CUs.

Spectrum of Superhypergraphs via Flows

open access: yesJournal of Mathematics, Volume 2022, Issue 1, 2022., 2022
For any n ∈ ℕ and given nonempty subset V, the concept of n‐superhypergraphs is introduced by Florentin Smarandache based on Pn(V) (n‐th power set of V). In this paper, we present the novel concepts supervertices, superedges, and superhypergraph via the concept of flow.

Filling in pattern designs for incomplete pairwise comparison matrices: (quasi-)regular graphs with minimal diameter [PDF]

open access: yesOmega, 2020
Multicriteria Decision Making problems are important both for individuals and groups. Pairwise comparisons have become popular in the theory and practice of preference modelling and quantification.

Coloring the Voronoi tessellation of lattices

open access: yesJournal of the London Mathematical Society, Volume 104, Issue 3, Page 1135-1171, October 2021., 2021
Abstract In this paper we define the chromatic number of a lattice: It is the least number of colors one needs to color the interiors of the cells of the Voronoi tessellation of a lattice so that no two cells sharing a facet are of the same color. We compute the chromatic number of the root lattices, their duals, and of the Leech lattice, we consider ...

Efficient Radio Channel Allocation in Integrated mmWave/Sub‐6 GHz UAV‐Assisted Disaster Relief Networks

open access: yesMobile Information Systems, Volume 2021, Issue 1, 2021., 2021
The unmanned aerial vehicle‐ (UAV‐) assisted sub‐6 GHz disaster relief networks cannot meet high‐speed transmission requirements. In this paper, the millimeter wave (mmWave) frequency band is combined with the sub‐6 GHz frequency band to build a high‐speed UAV‐assisted disaster relief network.

A new definition of the kinematic breaking onset criterion validated with solitary and quasi-regular waves in shallow water

open access: yes, 2021
A large body of work has been devoted to the accurate detection and simulation of wave breaking in coastal areas. It is a key process for a wide range of engineering activities and environmental issues.

Boundary maps, germs and quasi-regular representations [PDF]

open access: yesAdvances in Mathematics, 2020
We investigate the tracial and ideal structures of $C^*$-algebras of quasi-regular representations of stabilizers of boundary actions. Our main tool is the notion of boundary maps, namely $\Gamma$-equivariant unital completely positive maps from $\Gamma$-

Quasi‐Identifier Recognition Algorithm for Privacy Preservation of Cloud Data Based on Risk Reidentification

open access: yesWireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021
Cloud computing plays an essential role as a source for outsourcing data to perform mining operations or other data processing, especially for data owners who do not have sufficient resources or experience to execute data mining techniques. However, the privacy of outsourced data is a serious concern.

Quasi-regular Sasakian and K-contact structures on Smale–Barden manifolds [PDF]

open access: yesRevista matemática iberoamericana, 2020
Smale-Barden manifolds are simply-connected closed 5-manifolds. It is an important and difficult question to decide when a Smale-Barden manifold admits a Sasakian or a K-contact structure.
