The category {\bf Rel}({\bf Nom})

open access: yes, 2023
The category ${\rm Rel}(\mathcal{C})$ may be formed for any category $\mathcal{C}$ with finite limits using the same objects as $\mathcal{C}$ but whose morphisms from $X$ to $Y$ are binary relations in $\mathcal{C}$, that is, subobjects of $X\times Y$. In this paper, concerning the topos ${\bf Nom}$, we study the category ${\bf Rel}({\bf Nom})$.

Graph Compression by BFS [PDF]

open access: yesAlgorithms, 2009
The Web Graph is a large-scale graph that does not fit in main memory, so that lossless compression methods have been proposed for it. This paper introduces a compression scheme that combines efficient storage with fast retrieval for the information in a node. The scheme exploits the properties of the Web Graph without assuming an ordering of the URLs,

Telomere length comparison between oral cells and blood cells among neonates

open access: yesThe Turkish Journal of Pediatrics, 2019
Telomere length, measured from blood cells, is commonly used as the standard telomere length of the whole body. The relationship between blood telomere length and oral telomere length is still unclear, especially among neonates.

Zeta-Regularization of the O(N) Non-Linear Sigma Model in D dimensions [PDF]

open access: yes, 1995
The O(N) non-linear sigma model in a $D$-dimensional space of the form ${\bf R}^{D-M} \times {\bf T}^M$, ${\bf R}^{D-M} \times {\bf S}^M$, or ${\bf T}^M \times {\bf S}^P$ is studied, where ${\bf R}^M$, ${\bf T}^M$ and ${\bf S}^M$ correspond to flat space,

Magnon-Mediated Dzyaloshinskii-Moriya Torque in Homogeneous Ferromagnets [PDF]

open access: yes, 2014
In thin magnetic layers with structural inversion asymmetry and spin-orbit coupling, a Dzyaloshinskii-Moriya interaction arises at the interface. When a spin wave current ${\bf j}_m$ flows in a system with a homogeneous magnetization {\bf m}, this ...

The Structure of Pseudo-BF /BF*-algebra

open access: yesEuropean Journal of Pure and Applied Mathematics, 2020
In this paper, we study the structure of pseudo-BF/BF*-algebra as a generalization of BF-algebra. We show how pseudo-BF/BF*-algebra and pseudo-BCK-algebra are related. Westudy some elementary properties related to pseudo-BF-algebra and pseudo-BF*-algebra.

Power consumption model of sector breathing based congestion control in mobile network

open access: yesDigital Communications and Networks, 2018
According to Cooper's law, the number of conversations per location doubles every two and a half years. Therefore, congestion control has become a promising research area. Nowadays small cell deployment has become a solution to deal with congestion.
