We investigate the interactions among the pion, the vector mesons and the external gauge fields in the holographic dual of massless QCD proposed in our previous paper [1] on the basis of probe D8-branes embedded into a D4-brane background in type IIA string theory. We obtain the coupling constants by performing both analytic and numerical calculation, and(More)
A great variety of computer vision tasks, such as rigid/nonrigid structure from motion and photometric stereo , can be unified into the problem of approximating a low-rank data matrix in the presence of missing data and out-liers. To improve robustness, the L 1-norm measurement has long been recommended. Unfortunately, existing methods usually fail to(More)
We consider aspects of dynamical baryons in a holographic dual of QCD that is proposed on the basis of a D4/D8-brane configuration. We construct a soliton solution carrying a unit baryon number and show that it is given by an instanton solution of four-dimensional Yang-Mills theory with fixed size. The Chern-Simons term on the flavor D8-branes plays a(More)
In this paper, we revisit the classical perspective-n-point (PnP) problem, and propose the first non-iterative O(n) solution that is fast, generally applicable and globally optimal. Our basic idea is to formulate the PnP problem into a functional minimization problem and retrieve all its stationary points by using the Gr"obner basis technique. The novelty(More)
abstract We study the decay of unstable Dp-branes when the world-volume gauge field is turned on. We obtain the relevant Dp-brane boundary state with electric and magnetic fields by boosting and rotating the rolling tachyon boundary state of a D(p − 1)-brane and then T-dualizing along one of the transverse directions. A simple recipe to turn on the gauge(More)
