We find supertubes with arbitrary (and not necessarily planar) cross-section; the stability against the D2-brane tension is due to a compensation by the local momentum generated by Born-Infeldâ€¦ (More)

Progesterone is a gonadal steroid hormone whose physiological effects extend well beyond the strict confines of reproductive function. In fact, progesterone can have important effects on a variety ofâ€¦ (More)

The AdS/dCFT correspondence is used to show that a planar q-dimensional supersymmetric CFT defect expands, under the addition of electric charge and angular momentum, to a supersymmetricâ€¦ (More)

The Penrose limits of a D5-brane wrapped on the sphere of AdS5 Ã— S and connected to the boundary by N fundamental strings, which is dual to the baryon vertex of the N = 4 SU(N) super Yang-Millsâ€¦ (More)

We study the two-centred AdS7Ã—S solution of eleven-dimensional supergravity using the Euclidean path-integral approach, and find that it can be interpreted as an instanton, signalling the splittingâ€¦ (More)

The TST-dual of the general 1/4-supersymmetric D2-brane supertube is identified as a 1/4-supersymmetric IIA â€˜supercurveâ€™: a string with arbitrary transverse displacement travelling at the speed ofâ€¦ (More)
