Dynamics of Oxygen-Plankton Model with Variable Zooplankton Search Rate in Deterministic and Fluctuating Environments
(MDPI, 2022-05-11)
It is estimated by scientists that 50–80% of the oxygen production on the planet comes from the oceans due to the photosynthetic activity of phytoplankton. Some of this production is consumed by both phytoplankton and ...
On the Stabilization of a Network of a Class of SISO Coupled Hybrid Linear Subsystems via Static Linear Output Feedback
(MDPI, 2022-03-25)
This paper deals with the closed-loop stabilization of a network which consists of a set of coupled hybrid single-input single-output (SISO) subsystems. Each hybrid subsystem involves a continuous-time subsystem together ...
Theoretical approach to atomic-scale nanoplasmonics as probed by light and swift electrons
(2021-05-06)
This thesis tackles the theoretical description of atomic-scale features in plasmonic nanostructures asprobed by light and swift electrons. Plasmonic nanostuctures are known to localize and enhanceelectromagnetic fields ...
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 ...
Relativistic force between fast electrons and planar targets
(IOP Publishing, 2014-07-30)
The full retarded electromagnetic force experienced by swift electrons moving parallel to planar boundaries is revisited, for both metallic and dielectric targets, with special emphasis on the consequences in electron ...
On the Stabilization through Linear Output Feedback of a Class of Linear Hybrid Time-Varying Systems with Coupled Continuous/Discrete and Delayed Dynamics with Eventually Unbounded Delay
(MDPI, 2022-04-23)
This research studies a class of linear, hybrid, time-varying, continuous time-systems with time-varying delayed dynamics and non-necessarily bounded, time-varying, time-differentiable delay. The considered class of systems ...
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 ...
Isolation of Cancer-Derived Exosomes Using a Variety of Magnetic Nanostructures: From Fe3O4 Nanoparticles to Ni Nanowires
(MDPI, 2020-08-25)
Isolating and analyzing tumor-derived exosomes (TEX) can provide important information about the state of a tumor, facilitating early diagnosis and prognosis. Since current isolation methods are mostly laborious and ...
On some new mathematical models for infective diseases: analysis, equilibrium, positivity and vaccination controls
(2015-11-04)
Por un lado, cuando la enfermedad se desarrolla mediante la transmisión de los agentes patógenos de un individuo enfermo a otro, como puede ser el caso del SIDA, o la gripe, se le llama enfermedad infecciosa, mientras que ...
On the Stability and Equilibrium Points of Multistaged SI (n) R Epidemic Models
(Hindawi Publishing, 2015)
This paper relies on the concept of next generation matrix defined ad hoc for a new proposed extended SEIR model referred to as SI(n)R-model to study its stability. The model includes n successive stages of infectious ...
