Mammalian cell culture has served as an invaluable tool in cell biology for several decades. Mono­ layers of adherent cells grown on flat and rigid two-dimensional (2D) substrates, such as polysty­ rene or glass, have evolved as the mainstay in conventional cell culture systems. Two-dimensional cell culture studies have played a pivotal role in furthering our understanding of developmental biol...

Precipitates of the ordered L12 ’ phase (dispersed in the face-centered cubic or FCC  matrix) were imaged in Rene 88 DT, a commercial multicomponent Ni-based superalloy, using energy filtered transmission electron microscopy (EFTEM). Imaging was performed using the Cr, Co, Ni, Ti and Al elemental L-edges in the energy loss spectrum. Manual and automated segmentation procedures were utilized f...

This paper compares two methods for re ning uncertain knowledge bases using propositional certainty-factor rules. The rst method, implemented in the Rapture system, employs neural-network training to rene the certainties of existing rules but uses a symbolic technique to add new rules. The second method, based on the one used in the Kbann system, initially adds a complete set of potential new r...

Precipitates of the ordered L1(2) gamma' phase (dispersed in the face-centered cubic or FCC gamma matrix) were imaged in Rene 88 DT, a commercial multicomponent Ni-based superalloy, using energy-filtered transmission electron microscopy (EFTEM). Imaging was performed using the Cr, Co, Ni, Ti and Al elemental L-absorption edges in the energy loss spectrum. Manual and automated segmentation proce...
