A new framework classifies PL-types for every triangulated 4-manifold with up to six pentachora, succeeding except on the 4-sphere, CP^2 and QS^4(2) where at most four, three and two types appear respectively.
Knot traces of alternating knots and the newly defined extended alternating knots admit PALFs whose regular fibers have genus equal to the number of white regions in their planar graphs.
A combinatorial extension of a PALF construction produces genus-1 fiber versions on knot traces of Legendrian positive twist knots and positive torus knots T_{2,2n+1} while preserving the diffeomorphism type of the total space.
