Transient Cherenkov radiation from an inhomogeneous string excited by an ultrashort laser pulse at superluminal velocity [PDF]
, 2013 An optical response of one-dimensional string made of dipoles with a periodically varying density excited by a spot of light moving along the string at the superluminal (sub-luminal) velocity is theoretically studied.

Reconstruction of piano hammer force from string velocity [PDF]
The Journal of the Acoustical Society of America, 2016 A method is presented for reconstructing piano hammer forces through appropriate filtering of the measured string velocity. The filter design is based on the analysis of the pulses generated by the hammer blow and propagating along the string. In the five lowest octaves, the hammer force is reconstructed by considering two waves only: the incoming wave

Integral Hoisting Remote Control Heavy Load Tower for Coiled Tubing Operation
Shiyou jixie, 2021 When the velocity string operation was carried out in South Sulige Block, the existing tower could not meet the requirements of field construction, therefore, the integral hoisting remote control heavy load tower was developed.

Journal of High Energy Physics, 2020 We compute holographically the energy loss of a moving quark in various states of the D1-D5 CFT. In the dual bulk geometries, the quark is the end of a trailing string, and the profile of this string determines the drag force exerted by the medium on the

String dynamics near a Kaluza-Klein black hole [PDF]
, 1999 The dynamics of a string near a Kaluza-Klein black hole are studied. Solutions to the classical string equations of motion are obtained using the world sheet velocity of light as an expansion parameter. The electrically and magnetically charged cases are

Shiyou jixie, 2020 It has been found in practice that the production of many gas wells has decreased after running the velocity string. To explain this phenomenon, firstly, using the 65 well-time velocity string flow pressure test data reported in the public literature ...

, 1997 We solve the Cauchy problem for the relativistic closed string in Minkowski space $M^{3+1}$, including the cases where the initial data has a knot like topology.

Unified model for vortex-string network evolution
, 2004 We describe and numerically test the velocity-dependent one-scale (VOS) string evolution model, a simple analytic approach describing a string network with the averaged correlation length and velocity.
