Supersymmetric Intersecting Branes in Time-dependent Backgrounds
We construct a family of supersymmetric solutions in time-dependent
backgrounds in supergravity theories. One class of the solutions are
intersecting brane solutions and another class are brane solutions in pp-wave
backgrounds, and their intersection rules are also given. The relation to
existing literature is also discussed. An example of D1-D5 with linear null
dilaton together with its possible dual theory is briefly discussed.Comment: 12 pages, corrected typo, added reference, to appear in Phys. Rev.
Anisotropic imbibition on surfaces patterned with polygonal posts
We present and interpret lattice Boltzmann simulations of thick films
spreading on surfaces patterned with polygonal posts. We show that the
mechanism of pinning and depinning differs with the direction of advance, and
demonstrate that this leads to anisotropic spreading within a certain range of
material contact angles.Comment: DSFD Proceedings 201
