background: high-velocity carbon ion beams represent the most advanced tool for radiotherapy of deep-seated tumors. currently, the superiority of carbon ion therapy is more prominent on lung cancer or hepatomas. materials and methods: the data for lateral straggling and projected range of monoenergetic 290 mev/u (3.48 gev) carbon ions in muscle tissue were obtained from the stopping and range o...

When an electron beam is fired into an imploding target in order to initiate a fastignition-type propagating burn, spreading of the electrons occurs within the beam. The spread in the direction of motion (straggling) and the spread perpendicular to the direction of motion (blooming), as well as the energy lost as a result of these phenomena, can be defined by three equations. Previously, a prog...

Differences in dispersal abilities have been implicated for causing disparate evolutionary patterns between Columbicola and Physconelloides lice (Insecta: Phthiraptera). However, no study has documented straggling (when lice are found on atypical hosts) rates within these lineages. We used the fact that the Galapagos Hawk, Buteo galapagoensis (Gould) (Falconiformes) feeds on the Galapagos Dove ...

Motivated by increasing dataset sizes, various MapReducebased similarity join algorithms have emerged. In our past work (to appear), we compared nine of the most prominent algorithms experimentally. Surprisingly, we found that their runtimes become inhibitively long for only moderately large datasets. There are two main reasons. First, data grouping and replication between Map and Reduce relies...

Rutherford Backscattering Spectrometry (RBS) is a widely used method for the surface layer analysis of solids. This lecture gives a brief introduction into the method, and describes scattering kinematics, scattering cross-section data, stopping power data, detector resolution issues, and electronic energy loss straggling in some detail. Computer codes for the simulation of RBS spectra and RBS d...
