Numerical analysis of electro-convection in dielectric liquids with residual conductivity
(AIP Publishing, 2022)
Injection-induced electro-convection (EC) of dielectric liquids is a fundamental problem in electrohydrodynamics. However, most previous studies with this type of EC assume that the liquid is perfectly insulating. By ...

Numerical Study of a Plane Poiseuille Channel Flow of a Dielectric Liquid Subjected to Unipolar Injection
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
In this paper, the interaction between a plane Poiseuille channel flow and an electroconvective movement induced by the electric field is numerically investigated. A flow is generated by an inlet parabolic profile in a ...

Compact Balanced Dual-Band Bandpass Filter Based on Modified Coupled-Embedded Resonators
(Institute of Electrical and Electronics Engineers, 2017)
A new compact balanced dual-band bandpass filter based on coupled-embedded resonators with modified ground plane is presented in this work. Common-mode is rejected within the two differential passbands by symmetrically ...

Low-frequency excitation of leaky modes in a microstripline with a top cover
(2011)
This paper studies the excitation of a physical leaky mode in a covered microstrip structure at low frequencies. We calculate the current excited in the line by a delta-gap voltage source via a full wave analysis based on ...

Decoherence as a signature of an excited-state quantum phase transition
(American Physical Society, 2008)
We analyze the decoherence induced on a single qubit by the interaction with a two-level boson system with critical internal dynamics. We explore how the decoherence process is affected by the presence of quantum phase ...

Hyperspectral image processing for the identification and quantification of lentiviral particles in fluid samples
(Springer Nature, 2021-08)
Optical spectroscopic techniques have been commonly used to detect the presence of biofilm-forming pathogens (bacteria and fungi) in the agro-food industry. Recently, near-infrared (NIR) spectroscopy revealed that it is ...

Finite amplitude electroconvection induced by strong unipolar injection between two coaxial cylinders
(AIP Publishing, 2014)
We perform a theoretical and numerical study of the Coulomb-driven electroconvection flow of a dielectric liquid between two coaxial cylinders. The specific case where the inner to outer diameter ratio is 0.5 is analyzed. ...

Connection between decoherence and excited state quantum phase transitions
(American Institute of Physics, 2009)
In this work we explore the relationship between an excited state quantum phase transition (ESQPT) and the phenomenon of quantum decoherence. For this purpose, we study how the decoherence is affected by the presence of a ...

Entropies and IPR as Markers for a Phase Transition in a Two-Level Model for Atom–Diatomic Molecule Coexistence
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
A quantum phase transition (QPT) in a simple model that describes the coexistence of atoms and diatomic molecules is studied. The model, which is briefly discussed, presents a second-order ground state phase transition in ...

The role of digital technologies in health and long-term care sectors
(Publications Office of the European Union, 2021-02)
The role of digital technologies in health and long-term care sectors has been manifold. Digital technologies have, amongst others, transformed the delivery of health and care services and generated new type of professional ...
