Electronic correlation effects on the neutralization of Ga+ scattered by a gold surface
(American Physical Society, 2017-08)
The monotonous increasing with temperature behavior of the neutralization of Ga+ scattered by a gold surface plus the nonmagnetic character of the ion induced to disregard the important electronic correlation effects. In ...
Low energy ion scattering in He/HOPG system
(Elsevier Science, 2008-02)
Low energy ion scattering (LEIS) is a unique tool in surface analysis, since it provides the atomic composition of the outer atomic layer, and time of flight ion scattering (TOF) is a non-destructive method of analysis ...
Large neutral fractions in collisions of Li+ with a highly oriented pyrolytic graphite surface:Resonant and Auger mechanisms
(American Physical Society, 2008-12)
We report measurements of neutral atom fractions for Li+ scattered by a highly oriented pyrolytic graphite surface as a function of the incident ion energy and exit angle. We found an unexpected large neutralization ...
A Design Methodology of Multiresonant Controllers for High Performance 400 Hz Ground Power Units
(Institute of Electrical and Electronics Engineers, 2019)
In aerospace applications, a ground power unit has to provide balanced and sinusoidal 400 Hz phase-to-neutral voltages to unbalanced and nonlinear single-phase loads. Compensation of high-order harmonics is complex, as the ...
Effective theory for neutral resonances and a statistical dissection of the ATLAS diboson excess
(Springer, 2015-12-15)
We classify the complete set of dimension-5 operators relevant for the resonant production of a singlet of spin 0 or 2 linearly coupled to the Standard Model (SM). We compute the decay width of such states as a function ...

The characteristics of a nonlinear vibration neutralizer
(Academic Press Ltd Elsevier B.V. Ltd, 2012-06-18)
This paper concerns an investigation into the use of cubic nonlinearity in a vibration neutralizer to improve its effectiveness. It is assumed that the frequency of the harmonic excitation is well above the resonance ...

Modeling and Dynamic Analysis of an Electrical Helmholtz Resonator for Active Control of Resonant Noise
(2017-10-01)
This paper describes a theoretical and experimental investigation into an electrical Helmholtz resonator (EHR): that is, an active noise control (ANC) loudspeaker used in conjunction with a microphone and a feedback ...
Present bounds on new neutral vector resonances from electroweak gauge boson pair production at the LHC
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
Several extensions of the standard model predict the existence of new neutral spin-1 resonances associated with the electroweak symmetry breaking sector. Using the data from ATLAS (with integrated luminosity of L = 1.02 ...
