متن کاملNNπ from the effective field theory point of view : short comings and gains ∗
Based on a counting scheme for the application of chiral perturbation theory to pion production in NN collisions p-wave production is studied. It is demonstrated that, contrary to the s-wave production where loops enter at too low an order to allow the scheme predictive power, there are certain p-wave observables where parameter free predictions are possible. These predictions are consistent wi...

متن کاملThe comings and goings of homing endonucleases and mobile introns.
In this issue Belfort and coworkers (1) report the isolation and characterization of a thermostable endonuclease from the archaebacterium Desulfurococcus mobilis. Remarkably, the enzyme is encoded in an intron in the single gene for 23S rRNA and is expressed only after the corresponding RNA segment is excised from the newly made rRNA. Archaebacterial introns are unique in that their excision is...
