On the spectra of token graphs of cycles and other graphs
(Elsevier, 2023-09-11)
Article
Open AccessThe k-token graph of a graph G is the graph whose vertices are the k-subsets of vertices from G, two of which being adjacent whenever their symmetric difference is a pair of adjacent vertices in G. It is a known result ... -
Discovering important nodes of complex networks based on laplacian spectra
(2023-08-31)
Article
Open AccessKnowledge of the Laplacian eigenvalues of a network provides important insights into its structural features and dynamical behaviours. Node or link removal caused by possible outage events, such as mechanical and electrical ... -
Distance-layer structure of the De Bruijn and Kautz digraphs: analysis and application to deflection routing
(2023-07-29)
Article
Open AccessIn this article, we present a detailed study of the reach distance-layer structure of the De Bruijn and Kautz digraphs, and we apply our analysis to the performance evaluation of deflection routing in De Bruijn and Kautz ... -
Assessment of GRAS ionospheric measurements for ionospheric model assimilation
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-06-15)
Article
Open AccessWe conducted a study to assess the GNSS (Global Navigation Satellite System) Receiver for Atmospheric Sounding (GRAS) ionospheric data quality by processing Radio Occultation (RO) observations of ionospheric products. The ... -
New electronic tongue sensor array system for accurate liquor beverage classification
(2023-07-01)
Article
Open AccessThe use of sensors in different applications to improve the monitoring of a process and its variables is required as it enables information to be obtained directly from the process by ensuring its quality. This is now ... -
Counting configurations of limit cycles and centers
(2023-08)
Article
Open AccessWe present several results on the determination of the number and distribution of limit cycles or centers for planar systems of differential equations. In most cases, the study of a recurrence is one of the key points of ... -
Single and two-cells shape analysis from energy functionals for three-dimensional vertex models
(John Wiley & sons, 2023-07-21)
Article
Open AccessVertex models have been extensively used for simulating the evolution ofmulticellular systems, and have given rise to important global properties con-cerning their macroscopic rheology or jamming transitions. These models ... -
Reheating constraints in instant preheating
(American Physical Society, 2023-06-15)
Article
Open AccessWe use instant preheating as a mechanism to reheat the Universe when its evolution is modeled by a nonoscillating background. Once we obtain the reheating temperature, we calculate the number of e-folds using two different ... -
On remote electronic voting with both coercion resistance and cast-as-intended verifiability
(2023-08-01)
Article
Open AccessIn this work, we study two essential but apparently contradictory properties of electronic voting systems: coercion resistance (CR) and cast-as-intended verifiability (CAI). Informally, the CR property ensures that a voter ... -
On approximating shortest paths in weighted triangular tessellations
(2023-05-01)
Article
Open AccessWe study the quality of weighted shortest paths when a continuous 2-dimensional space is discretized by a weighted triangular tessellation. In order to evaluate how well the tessellation approximates the 2-dimensional ... -
On inertia and ratio type bounds for the k-independence number of a graph and their relationship
(Elsevier, 2023-07-15)
Article
Open AccessFor , the -independence number of a graph is the maximum number of vertices that are mutually at distance greater than . The well-known inertia and ratio bounds for the (1-)independence number of a graph, due to Cvetković ... -
Light distribution in tanks with the green seaweed Ulva ohnoi: effect of stocking density, incident irradiance and chlorophyll content
(2023-09-01)
Article
Restricted access - publisher's policyeaweed farming is an interesting technique to meet the future global food demand. However, it is essential to increase productivity in order to reduce the land surface required and make tank-based production more cost ...
