On p-Form Gauge Theories and their Conformal Limits
(Springer, 2021-03-02)
Relations between the various formulations of nonlinear p-form electrodynamics with conformal-invariant weak-field and strong-field limits are clarified, with a focus on duality invariant (2n - 1)-form electrodynamics and ...
On an SEIR Epidemic Model with Vaccination of Newborns and Periodic Impulsive Vaccination with Eventual On-Line Adapted Vaccination Strategies to the Varying Levels of the Susceptible Subpopulation
(MDPI, 2020-11-23)
This paper investigates a susceptible-exposed-infectious-recovered (SEIR) epidemic model with demography under two vaccination effort strategies. Firstly, the model is investigated under vaccination of newborns, which is ...
Astrocytes in Alzheimer’s Disease: Pathological Significance and Molecular Pathways
(MDPI, 2021-03-04)
Astrocytes perform a wide variety of essential functions defining normal operation of the nervous system and are active contributors to the pathogenesis of neurodegenerative disorders such as Alzheimer’s among others. ...
The Promotion of Sustainable Diets in the Healthcare System and Implications for Health Professionals: A Scoping Review
(MDPI, 2021-02-26)
The impacts of the current global food system are already visible in the environment and in the health of the population. The promotion of sustainable diets is key to counter the negative consequences. The healthcare system ...
RNA Localization and Local Translation in Glia in Neurological and Neurodegenerative Diseases: Lessons from Neurons
(MDPI, 2021-03-12)
Cell polarity is crucial for almost every cell in our body to establish distinct structural and functional domains. Polarized cells have an asymmetrical morphology and therefore their proteins need to be asymmetrically ...
Determinants of Corporate Anti-Corruption Disclosure: The Case of the Emerging Economics
(MDPI, 2021-03-20)
Corruption is a key factor that affects countries’ development, with emerging countries being a geographical area in which it tends to generate greater negative effects. However, few empirical studies analyze corruption ...
Self-Tuning Algorithm for Tuneable Clamping Table for Chatter Suppression in Blade Recontouring
(MDPI, 2021-03-13)
The production and repair of blades for aerospace engines and energy turbines is a complex process due their inherently low stiffness and damping properties. The final recontouring operation is usually performed by milling ...
Competition between nucleation and confinement in the crystallization of poly(ethylene glycol)/ large aspect ratio hectorite nanocomposites
(Elsevier Ltd, 2020-06-25)
The overall crystallization kinetics of polymer nanocomposites is determined by nucleation and crystal growth, which are both greatly affected by confinement. Heterogeneous nucleation is influenced by the interphase area ...
Fixed-Point Study of Generalized Rational Type Multivalued Contractive Mappings on Metric Spaces with a Graph
(MDPI, 2021-03-11)
The main result of this paper is a fixed-point theorem for multivalued contractions obtained through an inequality with rational terms. The contraction is an F-type contraction. The results are obtained in a metric space ...
e-Distance in Menger PGM Spaces with an Application
(MDPI, 2020-12-30)
The main purpose of the present paper is to define the concept of an e-distance (as a generalization of r-distance) on a Menger PGM space and to introduce some of its properties. Moreover, some coupled fixed point results, ...
