Concurrence of superposition [PDF]

open access: yesPhysical Review A, 2006
The bounds on concurrence of the superposition state in terms of those of the states being superposed are studied in this paper. The bounds on concurrence are quite different from those on the entanglement measure based on von Neumann entropy (Phys. Rev.

Towards Reconstruction of Complex Flow Fields Using Unit Flows

open access: yesFluids, 2021
Many complex turbulent flows in nature and engineering can be qualitatively regarded as being constituted of multiple simpler unit flows. The objective of this work is to characterize the coherent structures in such complex flows as a combination of ...

Influence of Spanwise and Streamwise Film Hole Spacing on Adiabatic Film Effectiveness for Effusion-Cooled Gas Turbine Blades

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2021
To meet the challenges of increased thermal loads and performance demands on aero-engine turbine blades, more advanced cooling techniques are required. This study used a modification of the well-known Goldstein equation to predict film effectiveness for ...

The Magic of Superposition: A Survey on Simultaneous Transmission Based Wireless Systems

open access: yesIEEE Access, 2022
In conventional communication systems, any interference between two communicating points is regarded as unwanted noise since it distorts the received signals.

Foundations of Quantum Mechanics

open access: yesEncyclopedia, 2022
Quantum mechanics is a mathematical formalism that models the dynamics of physical objects. It deals with the elementary constituents of matter (atoms, subatomic and elementary particles) and of radiation.

Entanglement of Superpositions [PDF]

open access: yesPhysical Review Letters, 2006
Given a bipartite quantum state (in arbitrary dimension) and a decomposition of it as a superposition of two others, we find bounds on the entanglement of the superposition state in terms of the entanglement of the states being superposed. In the case that the two states being superposed are biorthogonal, the answer is simple, and, for example, the ...

Can we hear the sounds of quantum superpositions? [PDF]

open access: yesMuzikologija, 2018
In this article I explore the possibility of being able to hear the sound of a quantum superposition of two sounds. What would it mean and is it feasible to explore performing an experiment that would allow us to test this notion?

Superposition, Composition and Separation of Casing Wave and P Wave of Formation in Cased Hole

open access: yesCejing jishu, 2023
From the actual measured waveform of cased holes in hard sandstone formation, it is found that the waveform of the first arrive wave changes with depth and is not a casing wave with constant velocity, which cannot be used to evaluate the cementing ...

Primena metoda ugaone superrezolucije za koncipiranje glave za samonavođenje protivradarske rakete / Angular superposition method and its application in the concept of the antiradar missile homing head [PDF]

open access: yesVojnotehnički Glasnik, 2003
U radu su analizirani sistemi klasične pasivne radarske detekcije ciljeva i definisani zahtevi superrezolucije dva vrlo bliska radarska cilja. Analizirane su referentne metode superrezolucije zasnovane na određivanju ugla dolazećih elektromagnetnih ...

Crystal structures of (12E)-12-(4-benzylidene)-7,7,16-trimethyl-3-(4-methylphenyl)-1-oxa-16-azatetracyclo[11.2.1.02,11.04,9]hexadeca-2(11),4(9)-dien-5-one and (12E)-12-(4-bromobenzylidene)-73-(4-bromophenyl)-,7,16-trimethyl-10-oxa-16-azatetracyclo[11.2.1.02,11.04,9]hexadeca-2(11),4(9)-dien-5-one

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2023
The title compounds, C32H35NO2, (I), and C30H29Br2NO2, (II), differ by the presence of a bromine atom instead of a methyl atom in the para position of two benzene rings of compound (II). The two compounds have a structural overlap r.m.s.
