We study the phase transitions of a fluid confined in capillary slit made from two adjacent walls, each which are periodic composite stripes different materials. For wide slits condensation occurs at pressure is described accurately by combination Kelvin equation and Cassie law for an averaged contact angle. However, narrow steps involving intermediate bridging phase, with corresponding pressur...

This paper examines price discovery for four Australian stocks cross-listed in New Zealand and five New Zealand stocks cross-listed in Australia for the period January 2002 to December 2005. Estimating Hasbrouck (1995) information shares over time reveals that the importance of the Australian market is growing.
