A Novel Vibrational Spectroscopy Using Spintronic-Plasmonic Antennas: Magneto-Refractive Surface-Enhanced Infrared Absorption
(American Institute of Physics, 2021-02-21)
We present experimental and theoretical results of the molecular sensing performance of a novel platform based on magnetic modulation of surface-enhanced infrared absorption spectroscopy. For this, we study the effect that ...
Qualitative analysis of a discrete-time phytoplankton–zooplankton model with Holling type-II response and toxicity
(Springer, 2021-10-09)
[EN]The interaction among phytoplankton and zooplankton is one of the most important
processes in ecology. Discrete-time mathematical models are commonly used for
describing the dynamical properties of phytoplankton and ...
A Modelization of the Propagation of COVID-19 in Regions of Spain and Italy with Evaluation of the Transmission Rates Related to the Intervention Measures
(MDPI, 2021-02-05)
Two discrete mathematical SIR models (Susceptible-Infectious-Recovered) are proposed for modelling the propagation of the SARS-CoV-2 (COVID-19) through Spain and Italy. One of the proposed models is delay-free while the ...
On a Discrete SEIR Epidemic Model with Two-Doses Delayed Feedback Vaccination Control on the Susceptible
(MDPI, 2021-04-18)
A new discrete susceptible-exposed-infectious-recovered (SEIR) epidemic model is presented subject to a feedback vaccination effort involving two doses. Both vaccination doses, which are subject to a non-necessarily identical ...
An SIRS Epidemic Model Supervised by a Control System for Vaccination and Treatment Actions Which Involve First-Order Dynamics and Vaccination of Newborns
(MDPI, 2021-12-23)
This paper analyses an SIRS epidemic model with the vaccination of susceptible individuals and treatment of infectious ones. Both actions are governed by a designed control system whose inputs are the subpopulations of the ...
A Study on COVID-19 Incidence in Europe through Two SEIR Epidemic Models Which Consider Mixed Contagions from Asymptomatic and Symptomatic Individuals
(MDPI, 2021-07-06)
The impact of the SARS-CoV-2 (COVID-19) on the world has been partially controlled through different measures of social isolation and prophylaxis. Two new SEIR (Susceptible-Exposed-Infected-Recovered) models are proposed ...
On the Properties of a Class of Impulsive Competition Beverton–Holt Equations
(MDPI, 2021-09-28)
This paper is devoted to a type of combined impulsive discrete Beverton–Holt equations in ecology when eventual discontinuities at sampling time instants are considered. Such discontinuities could be interpreted as impulses ...
Complex Formalism of the Linear Beam Dynamics
(IEEE-Institute of Electrical and Electronics Engineers, 2021-03)
It has long been known that the ellipse normally used to model the phase space extension of a beam in linear dynamics may be represented by a complex number which can be interpreted similar to a complex impedance in ...
Neutron Scattering as a Powerful Tool to Investigate Magnetic Shape Memory Alloys: A Review
(MDPI, 2021-05-18)
Magnetic shape memory alloys (MSMAs) are an interesting class of smart materials characterized by undergoing macroscopic deformations upon the application of a pertinent stimulus: temperature, stress and/or external magnetic ...
Temperature Dependent Stress–Strain Behavior and Martensite Stabilization in Magnetic Shape Memory Ni51.1Fe16.4Ga26.3Co6.2 Single Crystal
(MDPI, 2021-06-04)
The superelastic properties and stress-induced martensite (SIM) stabilization have been studied in a shape memory Ni51.1Fe16.4Ga26.3Co6.2 single crystal. The single crystal, characterized by a thermally induced forward ...
