Four-Brane and Six-Brane Interactions in M(atrix) Theory [PDF]

open access: yes, 1996
We discuss the proposed description of configurations with four-branes and six-branes in m(atrix) theory. Computing the velocity dependent potential between these configurations and gravitons and membranes, we show that they agree with the short distance

Reconstruction of piano hammer force from string velocity [PDF]

open access: yesThe 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

open access: yesShiyou 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.

Transient Cherenkov radiation from an inhomogeneous string excited by an ultrashort laser pulse at superluminal velocity [PDF]

open access: yes, 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.

Cause Analysis and Preventive Strategy of Gas Production Reduction by Velocity String Deliquification

open access: yesShiyou 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 ...

String dynamics near a Kaluza-Klein black hole [PDF]

open access: yes, 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

Unified model for vortex-string network evolution

open access: yes, 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.

No-Drag String Configurations for Steadily Moving Quark-Antiquark Pairs in a Thermal Bath [PDF]

open access: yes, 2006
We investigate the behavior of stationary string configurations on a five-dimensional AdS black hole background which correspond to quark-antiquark pairs steadily moving in an N=4 super Yang-Mills thermal bath.
