Multiplicity correlations between the current and target regions of the Breit frame in deep-inelastic scattering processes are studied. The correlations allow one to tag the rst-order perturbative QCD eeects and might be used to extract the behavior of the boson-gluon fusion rates as a function of the Bjorken variable. The behavior of the correlations is estimated analytically and analyzed usin...

The microstructure of enamel like most biological tissues has a hierarchical structure which determines their mechanical behavior. However, current studies of the mechanical behavior of enamel lack a systematic investigation of these hierarchical length scales. In this study, we performed macroscopic uni-axial compression tests and the spherical indentation with different indenter radii to prob...

The atomic structure and elastic properties of silicon carbide nanowires of different shapes and effective sizes were studied using density functional theory and classical molecular mechanics. Upon surface relaxation, surface reconstruction led to the splitting of the wire geometry, forming both hexagonal (surface) and cubic phases (bulk). The behavior of the pristine SiC wires under compressio...

The application of the finite element method to the inelastic analysis of structures and continua has received considerable attention over the last fifteen years [ 1-21 ]. To a large extent, this effort has been motivated by the need to safety and economically predict material response under conditions of extreme mechanical and thermal loading. Some examples are the design and analysis of press...
