On Confinement and Quarantine Concerns on an SEIAR Epidemic Model with Simulated Parameterizations for the COVID-19 Pandemic
(MDPI, 2020-10-07)
This paper firstly studies an SIR (susceptible-infectious-recovered) epidemic model without demography and with no disease mortality under both total and under partial quarantine of the susceptible subpopulation or of both ...
Interplay of Topological States on TI/TCI Interfaces
(MDPI, 2020-10-10)
Based on first-principles calculations, we study electronic structure of interfaces between a Z2 topological insulator (TI) SnBi2Te4 and a topological crystalline insulator (TCI) SnTe. We consider two interface models ...

Graphene-coffee waste derived carbon composites as electrodes for optimized lithium ion capacitors Author links open overlay panel
(Pergamon-Elsevier, 2020-06)
Herein we report an easy, ecofriendly and cheap synthetic approach for the preparation of carbon composites from the pyrolysis and activation of coffee waste and graphene oxide, and their evaluation as potential electrodes ...
Study of Electromagnetic Decays of Orbitally Excited Xi(C) Baryons
(American Physical Society, 2020-10-26)
Using 980 fb(-1) of data collected with the Belle detector operating at the KEKB asymmetric-energy e(+) e(-) collider, we report a study of the electromagnetic decays of excited charmed baryons Xi(c)(2790) and Xi(c)(2815). ...
Multivalued Fixed Point Results for Two Families of Mappings in Modular-Like Metric Spaces with Applications
(Wiley-Hindawi, 2020-11-16)
The aim of this research work is to find out some results in fixed point theory for a pair of families of multivalued mappings fulfilling a new type of U-contractions in modular-like metric spaces. Some new results in graph ...
Skills Needs of the Civil Engineering Sector in the European Union Countries: Current Situation and Future Trends
(MDPI, 2020-10-16)
The construction sector has always occupied a strategic place in the European economy. The European construction industry suffered during the 2007–2008 global financial crisis, and today the sector is undergoing a recovery ...
Guiding students towards an understanding of the electromotive force conceptin electromagnetic phenomena through a teaching-learning sequence
(American Physical Society, 2020-08-03)
In this work we present the application of design based research (DBR) methodology to conduct a systematic iterative study of the design and implementation of a teaching-learning sequence (TLS) on emf (electromotive force). ...
Fabrication of a Novel Magnetic Topological Heterostructure and Temperature Evolution of its Massive Dirac Cone
(Nature, 2020-09-24)
Materials that possess nontrivial topology and magnetism is known to exhibit exotic quantum phenomena such as the quantum anomalous Hall effect. Here, we fabricate a novel magnetic topological heterostructure Mn4Bi2Te7/Bi2Te3 ...
Effects of a snack enriched with carob and Undaria pinnatifida (wakame) on metabolic parameters in a double blind, randomized clinical trial in obese patients
(SENPE-Arán Ediciones, 2020-07-13)
Introduction: Introduction: the composition of snack foods likely influences the overall effect that snacking has on metabolism and obesity. The objective of the current study was to assess the responses to two different ...
