  3D Morphable Models (3DMMs) are powerful statistical models of 3D facial shape and texture, and are among the state-of-the-art methods for reconstructing facial shape from single images. With the advent of new 3D sensors, ...

• Data-driven study of discolouration material mobilisation in trunk mains 

  Gregory, Meyers; Zoran, Kapelan; Edward, Keedwell (MDPI, 2017-10-24)

  It has been shown that sufficiently high velocities can cause the mobilisation of discolouration material in water distribution systems. However, how much typical hydraulic conditions affect the mobilisation of discolouration ...

• The spin evolution of fast-rotating, magnetized super-Chandrasekhar white dwarfs in the aftermath of white dwarf mergers 

  Becerra, L; Rueda, JA; Lorén-Aguilar, P; Garcia-Berro, E (American Astronomical Society / IOP Publishing, 2018-04-20)

  The evolution of the remnant of the merger of two white dwarfs is still an open problem. Furthermore, few studies have addressed the case in which the remnant is a magnetic white dwarf with a mass larger than the Chandrasekhar ...

• Cobalt mineralisation in Cornwall - A new discovery at Porthtowan 

  Rollinson, GK; Le Boutillier, N; Selley, R (Ussher Society, 2018-05-16)

  Although cobalt mineralisation has been noted in Cornwall and Devon in the mining literature, there are limited details of its production and paragenesis; detailed mineral studies of cobalt are almost non-existent. This ...

• Young star clusters in nearby molecular clouds 

  Getman, KV; Kuhn, MA; Feigelson, ED; Broos, PS; Bate, MR; Garmire, GP (Oxford University Press, 2018-02-22)

• The Skaergaard trough layering: sedimentation in a convecting magma chamber 

  Vukmanovic, Z; Holness, MB; Monks, K; Andersen, JCØ (Springer Verlag, 2018-04-25)

  The upper parts of the floor cumulates of the Skaergaard Intrusion, East Greenland, contain abundant features known as troughs. The troughs are gently plunging synformal structures comprising stacks of crescentic modally ...
