\If you want to think about thinking, you have to think about thinking about something." | Seymour Papert A softbot (software robot) is a program that interacts with a software environment by issuing commands and interpreting the environment's feedback. Because softbots are much easier to build than physical robots, softbots are an attractive substrate for machine-learning and agentarchitecture...

A new monotonicity principle and an L stability theorem are es tablished for a discrete obstacle problem which is de ned by a piece wise linear nite element discretization of a continuous problem This discrete monotonicity principle extends the discrete maximum princi ple of Ciarlet from linear equations to obstacle problems As an application of the monotonicity principle and the L stability th...

We have measured the Coulomb dissociation of 8B into 7Be and proton at 254 MeV/nucleon using a large-acceptance focusing spectrometer. The astrophysical S17 factor for the 7Be(p,γ)8B reaction at Ec.m. = 0.25−2.78 MeV is deduced yielding S17(0) = 20.6± 1.2 (exp.) ± 1.0 (theo.) eV-b. This result agrees with the presently adopted zero-energy S17 factor obtained in directreaction measurements and w...
