Automated Dna Sequencers: The Next Generation

Optically detected DNA sequencing technologies facilitate sequencing the 3 billion base pairs of the human genome. Faster, higher throughput optically detected electrophoresis instrumentation will be necessary to bring the cost of sequencing the entire genome down and to complete the project by 2005.

A game of billiards with Spatial-Solitary Waves in KTP

A RADICALLY NEW WAY TO THINK OF THE PROBLEM OF MULTI-DIMENSIONAL SELF-TRAPPING HAS COME TO LIGHT IN QUADRATIC NONLINEAR IN TERACTIONS. IN THIS ARTICLE, THE AUTHORS NOT ONLY SHOW THAT THE DIFFRACTION IN SPATIAL WALKOFF CAN BE DEFEATED, BUT THAT A GENUINE GAME OF BILLIARDS CAN BE PLAYED WITH STRONGLY COUPLED FUNDAMENTAL AND HARMONIC FIELDS.
