DOI: 10.1016/j.celrep.2019.03.013
Abstract: During development, oligodendrocyte progenitor cells (OPCs) migrate extensively throughout the spinal cord. However, their migration is restricted at transition zones (TZs). At these specialized locations, unique glial cells in both zebrafish and mice play a… read more here.

DOI: 10.1016/j.conbuildmat.2020.121167
Abstract: Abstract Transition zones are vulnerable areas in railway lines, which usually need frequent extra maintenances. Thus, various countermeasures have been proposed to reduce the sudden change of track stiffness in transition zones. However, most of… read more here.

DOI: 10.1016/j.conbuildmat.2021.123332
Abstract: Abstract Using meso-structural representations of concrete, with aggregates dispersed in mortar, has become a standard approach for damage and fracture analysis. However, there is no full agreement on appropriate modelling of different phases and on… read more here.

DOI: 10.1016/j.engstruct.2018.05.004
Abstract: Transition zones in railway tracks are the locations with considerable variation in the vertical stiffness of supporting structures. Typically, they are located near engineering structures, such as bridges, culverts, tunnels and level crossings. In such… read more here.

DOI: 10.1016/j.ijsolstr.2021.111122
Abstract: Abstract Macroscopic austenite-martensite transition zones in thin superelastic NiTi wires subjected to stretching, twisting and their combination were reconstructed via diffraction/scattering computed tomography. The method allows to visualize spatial distributions of both phases from a… read more here.

DOI: 10.1016/j.sandf.2018.12.013
Abstract: Abstract Railway ballasted tracks at transition zones from embankment sections to bridge sections (or the reverse) suffer not only from seismic motions, but also from differential settlements during seismic motions. Therefore, an attempt is made… read more here.

DOI: 10.1016/j.trgeo.2019.100260
Abstract: Abstract Track transitions such as bridge approaches, road crossings and shifts from slab track to ballasted track are common locations where track degradation accelerates due to dynamic and high impact forces; as a consequence there… read more here.

DOI: 10.1093/biolinnean/blaa120
Abstract: Transition zones are problematic in biogeographical classification as they represent artificial biotic areas. A review of transition zones into existing biogeographical classifications shows conflicting area taxonomies. While many authors consider transition zones as overlap zones… read more here.
