Derivation of the bidomain equations for a beating heart with a general microstructure
No full textA novel multiple scales method is formulated that can be applied to problems which have an almost periodic microstructure not in Cartesian coordinates but in a general curvilinear coordinate system. The method is applied to a model of the electrical activity of cardiac myocytes and used to derive a version of the bidomain equations describing the macroscopic electrical activity of cardiac tissue. The treatment systematically accounts for the nonuniform orientation of the cells within the tissue and for deformations of the tissue occurring as a result of the heart bea

The study of asymptotically fine wrinkling in nonlinear elasticity using a boundary layer analysis
No full textExtrusion of power-law shear thinning fluids with small exponent.
No full textThe slow flow of power-law shear-thinning fluids during extrusion is considered for materials where the exponent is asymptotically close to zero. Such flows arise in a number of practical industrial problems and give rise to some unexpected effects. Three different regions of extrusion flow are examined. First, some simple results for unidirectional flow in a one-dimensional channel are considered. Secondly, the region near to the die exit is then considered, and it is noted that an exponential asymptotic approach may be used to completely solve the problem of slow flow in a wedge with a sink at the vertex. Finally, the ram region of the extruder is considered and a detailed analysis is given of flow in a corner driven by the movement of one of the walls
Vacuum moulding of a superplastic in two dimensions
No full textA mathematical model is proposed for the process of vacuum superplastic forming. The model exploits the fact that in most industrial applications the sheet aspect ratio (thickness/sheet width) is small. After an initial consideration of some of the more general properties and the literature of superplastic materials, the elastic/plastic deformation of an internally-inflated thin-walled cylinder is examined. Plates of arbitrary geometry are then considered. A quasisteady model in which the sheet moves through a sequence of steady states is developed. Some simplified closed-form solutions are examined, but for general cases a system of nonlinear partial differential equations must be solved numerically. An efficient and accurate semi-explicit numerical scheme is proposed and a simplified stability analysis is presented; the method is then used to compute properties of superplastic vacuum moulded sheets in a number of practically motivated cases
Genomic divergence during speciation driven by adaptation to altitude
No full textEven though Darwin's "On the Origin of Species" implied selection being the main driver of species formation, the role of natural selection in speciation remains poorly understood. In particular, it remains unclear how selection at a few genes can lead to genome-wide divergence and the formation of distinct species. We used a particularly attractive clear-cut case of recent plant ecological speciation to investigate the demography and genomic bases of species formation driven by adaptation to contrasting conditions. High altitude Senecio aethnensis and low altitude Senecio chrysanthemifolius live at the extremes of a mountain slope on Mt. Etna, Sicily and form a hybrid zone at intermediate altitudes, but remain morphologically distinct. Genetic differentiation of these species was analysed at the DNA polymorphism and gene expression levels by high-throughput sequencing of transcriptomes from multiple individuals. Out of ca. 18,000 genes analysed, only a small number (90) displayed differential expression between the two species. These genes showed significantly elevated species differentiation (FST and Dxy), consistent with diversifying selection acting on these genes. Genome-wide genetic differentiation of the species is surprisingly low (FST = 0.19), while ca. 200 genes showed significantly higher (FDR < 1%; mean outlier FST > 0.6) interspecific differentiation and evidence for local adaptation. Diversifying selection at only a handful of loci may be enough for the formation and maintenance of taxonomically well-defined species, despite on-going gene flow. This provides an explanation of why many closely-related species (in plants in particular) remain phenotypically and ecologically distinct despite on-going hybridisation, a question that has long puzzled naturalists and geneticists alike
