Properties of spontaneous mutational variance and covariance for wing size and shape in Drosophila melanogaster.
We estimated mutational variance-covariance matrices, M, for wing shape and size in two genotypes of Drosophila melanogaster after 192 generations of mutation accumulation. We characterized 21 potentially independent aspects of wing shape and size using geometric morphometrics, and analyzed the data using a likelihood-based factor-analytic approach. We implement a previously unused analysis tha...
متن کاملEffect of Cell Size and Shape on Electric Field Threshold and Critical Transmembrane Voltage for Electroporation
Introduction: Electroporation is a technique for increasing the permeability of the cell membrane to otherwise non-permeate molecules due to an external electric field. This permeability enhancement is detectable if the induced transmembrane voltage becomes greater than a critical value which depends on the pulse strength threshold. In this study, the variabil...
متن کاملLeaf N and P stoichiometry in relation to leaf shape and plant size for Quercus acutissima provenances across China
Plant stoichiometry in relation to the structure and function of biological systems has been investigated at multiple scales. However, few studies have focused on the roles of stoichiometry for a given species. In this study, we determined leaf N and P stoichiometry, leaf shape and plant size in three Quercus acutissima common gardens with different climatic and site conditions. In the three co...
متن کاملShape Spaces and Shape Modelling
This dissertation presents some of the recent developments in the modelling of shape spaces. Forming the basis for a quantitative analysis of shapes, this is relevant for many applications involving image recognition and shape classification. All shape spaces discussed in this work arise from the general situation of a Lie group acting isometrically on some Riemannian manifold. The first chapte...
متن کاملEFFICIENT SIMULATION FOR OPTIMIZATION OF TOPOLOGY, SHAPE AND SIZE OF MODULAR TRUSS STRUCTURES
The prevalent strategy in the topology optimization phase is to select a subset of members existing in an excessively connected truss, called Ground Structure, such that the overall weight or cost is minimized. Although finding a good topology significantly reduces the overall cost, excessive growth of the size of topology space combined with existence of varied types of design variables challe...
