Active cloaking of flexural waves in thin plates
Abstract An active cloak consists of a set of discrete multipole sources distributed in space. When the source positions and amplitudes are carefully specified the active field destructively interferes with an incident time harmonic wave so as to...

Disformal transformation of cosmological perturbations
Abstract We investigate the gauge-invariant cosmological perturbations in the gravity and matter frames in the general scalar–tensor theory where two frames are related by the disformal transformation. The gravity and matter frames are the...

A procedure for the characterization of electron transmission through Frisch grids
Abstract In Frisch grid ionization chambers special attention must be paid to the operating voltages in order to avoid unwanted collection of electrons on the Frisch grid. Collection of electrons on the grid will lead to a decreased signal to noise...

Numerical Modeling of Dependence of Separative Power of the Gas Centrifuge on the Length of Rotor
Abstract Numerical modelling and optimization of the gas flow and isotope separation in the Iguasu gas centrifuge (GC) for uranium enrichment have been performed for different lengths of the rotor. The calculations show that the specific separative...

Discharge Coefficient of 3-in-1 Hole with Various Inclination Angle and Hole Pitch
Abstract Discharge coefficients of 3-in-1 hole of three inclination angles and three spacing between holes are presented which described the discharge behavior of a row of holes. The inlet and outlet of the 3-in-1 hole both have a 15° lateral...

Light-cone gravity in AdS4
Abstract We obtain a closed form expression for the Action describing pure gravity, in light-cone gauge, in a four-dimensional Anti-de Sitter background. We perform a perturbative expansion of this closed form result to extract the cubic interaction ...

Constraints on the decay of the protons falling onto Sgr A⁎
Abstract In a recent Letter, an excess of 511 keV radiation from positron annihilation from the centre of the Galaxy was proposed to explain by the decay of the protons falling onto Sgr A⁎ while interpreting Sgr A⁎ as a gravitational vacuum star. In ...

Finite volume form factors in the presence of integrable defects
Abstract We developed the theory of finite volume form factors in the presence of integrable defects. These finite volume form factors are expressed in terms of the infinite volume form factors and the finite volume density of states and incorporate ...

N=2 gauge theories from wrapped five-branes
Abstract We present string duals of four-dimensional N=2 pure SU(N) SYM theory. The theory is obtained as the low energy limit of D5-branes wrapped on non-trivial two-cycles. Using seven-dimensional gauged supergravity and uplifting the result to...

SU(2) vortex configuration in Laplacian center gauge
Abstract We study how Laplacian center gauge identifies the vortex content of a thick SU(2) vortex configuration on the lattice. This configuration is a solution of the Yang–Mills classical equations of motion having vortex properties. We find that...

Research of Ionospheric Time-Delay Error Simulation in High Dynamic GPS Signal Simulator
Abstract The ionospheric time-delay is an important error source for GPS users. How to simulate the ionospheric error is one of the key problems that need to be solved in high dynamic GPS signal simulator design. The ionospheric effects are related...
