Modelling and validation of bacterial O-antigen conformations: ring puckering in Shigella flexneri 7a and 7b O-antigens as a case study by Timol, Zaheer

“…The results also suggest that puckering of β-DGlcpNAc does occur in S. flexneri 7a and 7b O-antigens but that it may be over represented in the simulations. Two general observations can be drawn from this study: (1) the 3,4-disubstitution of β-DGlcpNAc with two bulky substituents leads to the ring puckering out of the 4C1 conformer; and (2) the conformation and dynamic behaviour of β-D-GlcpNAc puckering is not accurately modelled by current methods, identifying the need for further enhancements to existing carbohydrate force fields.…”

Micromechanical modelling of advanced hierarchical composites by Griffiths, Emma

“…This issue may be addressed by impregnating the nanoporous metal with a polymer. In this work the behaviour of a polymer impregnated nanoporous gold (NPG) composite is explored using the finite element method in three different scenarios: linear elasticity, fracture and electrically stimulated actuation. …”
