Geological and climatic processes potentially alter speciation rates by generating and modifying barriers to dispersal. In Southeast Asia, two processes have substantially altered the distribution of land. Volcanic uplift produced many new islands during the Miocene-Pliocene and repeated sea level fluctuations during the Pleistocene resulted in intermittent land connections among islands. Each ...

Recently we presented a method for modeling a quantum system to a bath that explicitly correlates the system with the individual bath modes. We do this through representation of the bath by locally propagating Gaussians (LPG), which change in position and momentum but remain Gaussian in form. The explicit correlation of the system to the bath modes enters through the simultaneous use of a di†er...

The ambient index and temperature effects on the spectral profiles of two sets of long period gratings (LPGs) of different periods were investigated. The shorter period LPGs were found to be more sensitive than the longer period LPGs over identical ambient index ranges but less sensitive over identical temperature ranges. The coupling wavelength shifts due to temperature are also seen to be lin...

The goal of this project was to measure directly the volatilization of gas phase polychlorinated biphenyls (PCBs) from stabilized dredged material (SDM) in a • laboratory scale flux chamber. This study complements earlier field observations (Phase I) to estimate PCB fluxes from SDM being applied to a landfill (Korfiatis et. al., 2003, Miskewitz et al, 2004). Phase I included measurements of the...
