Multilayer optical strip for illumination, imaging and analysis
(TechConnect, 2015-06)
An optical device (multilayer optical strip, MOS) is presented. It is composed of a small-sized, strip-shaped, multilayer, planar structure connected to a control unit. Active and passive optical elements allow for controlling ...

Decoherence due to an excited-state quantum phase transition in a two-level boson model
(American Physical Society, 2009)
The decoherence induced on a single qubit by its interaction with the environment is studied. The environment is modeled as a scalar two-level boson system that can go through either first-order or continuous-excited-state ...

Partial Bell-State Analysis with Parametric down Conversion in the Wigner Function Formalism
(Hindawi Publishing Corporation, 2010)
We apply the Wigner function formalism to partial Bell-state analysis using polarization entanglement produced in parametric down conversion. Two-photon statistics at a beam-splitter are reproduced by a wave-like description ...

Numerical analysis of the stability of the Electrohydrodynamic (EHD) electroconvection between two plates
(IOP Publishing, 2008)
The time evolution of the problem of Electrohydrodynamic (EHD) convection in a liquid between two plates is analysed numerically. The equations are nondimensionalized using the ion drift velocity and the viscous time ...

Evolution of Gaussian wave packets in capillary jets
(American Physical Society, 2019)
A temporal analysis of the evolution of Gaussian wave packets in cylindrical capillary jets is presented through both a linear two-mode formulation and a one-dimensional nonlinear numerical scheme. These analyses are ...

The Invariant Two-Parameter Function of Algebras ψ
(MDPI, 2019-10)
At present, the research on invariant functions for algebras is very extended since Hrivnák and Novotný defined in 2007 the invariant functions y and j as a tool to study the Inönü–Wigner contractions (IW-contractions), ...

Thermal and electrohydrodynamic plumes: a compartive study
(AIP Publishing, 1996)
This paper deals with self similar thermal and electrohydrodynamic (EHD) plumes. The former arises from hot lines or points, whereas the latter arises when sharp metallic contours submerged in non conducting liquids ...

Simple Setup for Measuring the Response to Differential Mode Noise of Common Mode Chokes
(MDPI, 2020-02)
This work presents a technique to measure the attenuation of differential mode noise provided by common mode chokes. The proposed setup is a simpler alternative to the balanced setup commonly employed to that end, and ...

Use of Mutual Coupling to Decrease Parasitic Inductance of Shunt Capacitor Filters
(IEEE-Institute of Electrical and Electronics Engineers, 2015-12)
In this paper, we propose and study several new designs of a shunt capacitor filter with two surface-mount technology capacitors. These designs make use of mutual inductance effects to increase the attenuation provided by ...

Diagnostic accuracy of elastography and magnetic resonance imaging in patients with NAFLD: a systematic review and meta-analysis
(2021)
Background and Aims: Vibration-controlled transient elastography (VCTE), point shear wave elastography (pSWE), 2- dimensional shear wave elastography (2DSWE), magnetic resonance elastography (MRE), and magnetic resonance ...
