We demonstrate the generation of broadband up-converted multicolor array (BUMA) in a thin BK7 glass slide using two noncollinear weak near-IR laser pulses with various crossing angles. The BUMA signal arises from cubic nonlinear χ⁽³⁾:χ⁽³⁾ processes via cascaded four-wave mixing of the two incident beams. Broad and continuous tunability of...

Subduction zone earthquake and tsunami hazards affect tens of millions worldwide and the recurrence of these disasters can be evaluated with paleoseismic techniques, because earthquake cycles (and their supercycles) typically span many millennia. In these three chapters, I discuss a suite of analyses I use to evaluate the sedimentary record...
The trails included in this book will lead you to mountain-top vistas, lakes, waterfalls and old-growth forests, towering secondgrowth forests, rocky bluffs and alpine meadows. We've included a variety of trails:
• short walks for those seeking fresh air and a place to stretch their legs
• medium length trails...

Grazing cattle usually have access to streams as a
source of drinking water. A model was developed for the
personal computer to predict the bacterial quality of
these streams. The model estimates the number of
organisms that enter the stream by the direct deposit of
feces and by runoff from...
