With the rapid development of economy, the competition of tourism culture and tourism commodities is becoming more and more fierce, and the traditional national culture is also impacted, and its historical value is gradually hidden.Traditional cultural elements have strong cultural attributes and influence charm, so it is particularly important to

Abstract We present a new operator in the ambitwistor string which glues together correlators with fewer points or of lower genus.It underpins the recursive construction of tree-level CHY scattering amplitudes by ORG KELP WHOLE PLANT Dolan & Goddard, as well as the computation of loop integrands on a Riemann sphere by Geyer et al.The gluing operato

Target location is the basic application of a multistatic sonar system.Determining the position/velocity vector of a target from the related sonar observations is a nonlinear estimation problem.The presence of possible sensor Plymovent Filter position uncertainties turns this problem into a more challenging hybrid parameter estimation problem.Conve

Traceability information can be crucial for software maintenance, testing, automatic program repair, and various other software engineering tasks.Customarily, a vast amount of test code is created for systems to maintain and improve software quality.Today’s test systems may contain tens of thousands of tests.Finding the parts of code tested
