A biosynthetic approach to the discovery of novel bioactive peptides
(University of CambridgeDepartment of Chemical Engineering and Biotechnology, 2012-05-08)Peptides represent a source of novel therapeutics for recalcitrant human diseases, but screening for bioactivity from natural or synthetic sources can be uneconomic. In contrast, in vivo expression of peptides from DNA ...

A continuous/discontinuous Galerkin formulation for a strain gradient-dependent damage model
(4th European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS)4th European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS), 2004)The numerical solution of strain gradient-dependent continuum problems has been hindered by continuity demands on the basis functions. The presence of terms in constitutive models that involve gradients of the strain field ...

A p-adaptive scheme for overcoming volumetric locking during isochoric plastic deformation
(Solids, Structures and Coupled Problems in Engineering : ECCM-2001: 2nd European Conference on Computational MechanicsSolids, Structures and Coupled Problems in Engineering : ECCM-2001: 2nd European Conference on Computational Mechanics, 2001)A p-adaptive scheme is developed in order to overcome volumetric locking in low order finite elements. A special adaptive scheme is used which is based on the partition of unity concept. This allows higher order polynomial ...
