A bstract Recent work has shown how on-shell three-point amplitudes in gauge theory and gravity, representing the coupling to massive particles, correspond classical limit curvature spinors of linearised solutions. This connection, made explicit via KMOC formalism split metric signature, turns double copy scattering into Here, we extend this framework universal massless sector supergravity, whi...

This paper mainly aims at solving the problems of sampled data synchronization in digital substation based on Filed Programable Gate Array (FPGA). Compared with traditional substations, the design achieves data synchronization without connecting an external clock. Synchronization algorithm is based on Newton interpolation algorithm. The system consists of multi-channel data sampling module, syn...

In the research we used the simulator NS-3 with s...

This paper proposes a set of performance enhancements techniques aiming to improve the perceived performance of video transmission across the IEEE 802.11e network. The proposed mechanism preserves the video Quality of Experience (QoE) by protecting the I-Frames transmitted as part of the Group of Pictures (GoP) during queue congestion. The method is evaluated using the NS-3 simulator with the E...

DNA adenine methylase (Dam(-)) mutants of Salmonella enterica serovar Typhimurium contain reduced levels of FinP RNA encoded on the virulence plasmid. Dam methylation appears to regulate finP transcription, rather than FinP RNA stability or turnover. The finP promoter includes canonical -10 and -35 modules and depends on the sigma(70) factor. Regulation of finP transcription by Dam methylation ...

We complete the classification of parallelizable NS-NS backgrounds in type II super-gravity by adding the dilatonic case to the result of Figueroa-O'Farrill on the non-dilatonic case. We also study the supersymmetry of these parallelizable backgrounds. It is shown that all the dilatonic parallelizable backgrounds have sixteen supersymmetries. The parallelizable pp-wave backgrounds have been rec...
