On the Entropy of Events under Eventually Global Inflated or Deflated Probability Constraints. Application to the Supervision of Epidemic Models under Vaccination Controls
(MDPI, 2020-02-29)
This paper extends the formulation of the Shannon entropy under probabilistic uncertainties which are basically established in terms or relative errors related to the theoretical nominal set of events. Those uncertainties ...
Nanostructured giant magneto-impedance multilayers deposited onto flexible substrates for low pressure sensing
(Springer, 2012-04)
Nanostructured FeNi-based multilayers are very suitable for use as magnetic sensors using the giant magneto-impedance effect. New fields of application can be opened with these materials deposited onto flexible substrates. ...
Elucidating the role of shape anisotropy infaceted magnetic nanoparticles using biogenicmagnetosomes as a model
(Royal Society of Chemistry, 2020-08-14)
Shape anisotropy is of primary importance to understand the magnetic behavior of nanoparticles, but a rigorous analysis in polyhedral morphologies is missing. In this work, a model based on finite element techniques has ...
Magnetosomes could be protective shields against metal stress in magnetotactic bacteria
(Nature, 2020-07)
Magnetotactic bacteria are aquatic microorganisms with the ability to biomineralise membrane-enclosed magnetic nanoparticles, called magnetosomes. These magnetosomes are arranged into a chain that behaves as a magnetic ...
Magnetotactic bacteria for cancer therapy
(American Institute of Physics, 2020-08-21)
Magnetotactic bacteria (MTB) are aquatic microorganisms that are able to biomineralize membrane-enclosed magnetic nanoparticles called magnetosomes. Inside the MTB, magnetosomes are arranged in a chain that allows MTB to ...
The Performance of the Magneto-Impedance Effect for the Detection of Superparamagnetic Particles
(MDPI, 2020-03-31)
The performance of magneto-impedance sensors to detect the presence and concentration of magnetic nanoparticles is investigated, using finite element calculations to directly solve Maxwell’s equations. In the case ...
Half-Hedgehog Spin Textures in sub-100 nm Soft Magnetic Nanodots
(Royal Society Of Chemistry, 2020-09-28)
Topologically non-trivial structures such as magnetic skyrmions are nanometric spin textures of outstanding potential for spintronic applications due to their unique features. It is well known that Neel skyrmions of definite ...
On a New Epidemic Model with Asymptomatic and Dead-Infective Subpopulations with Feedback Controls Useful for Ebola Disease
(Hindawi Publishing Corporation, 2017-02-19)
This paper studies the nonnegativity and local and global stability properties of the solutions of a newly proposed SEIADR model which incorporates asymptomatic and dead-infective subpopulations into the standard SEIR model ...
Magnetocaloric Effect Caused by Paramagnetic Austenite–Ferromagnetic Martensite Phase Transformation
(MDPI, 2018-12-21)
In the present work, the magnetization of Ni50Mn17.5Ga25Cu7.5 alloy undergoing the first-order phase transition from paramagnetic austenite to ferromagnetic martensite was measured to evaluate the magnetic-field-induced ...
Metallic Glass/PVDF Magnetoelectric Laminates for Resonant Sensors and Actuators: A Review
(MDPI, 2017-05-31)
Among magnetoelectric (ME) heterostructures, ME laminates of the type Metglas-like/PVDF (magnetostrictive+piezoelectric constituents) have shown the highest induced ME voltages, usually detected at the magnetoelastic ...
