This paper reviews an approach to design using Genetic Algorithms as applied to the domain of composite material structures. We first discuss the concept of a Genetic Algorithm (GA) and the role it can play in design, namely as an evolutionary search optimizer based on simulation results. We then discuss the composite structure design problem and how GA’s can be used for design in this domain. ...

Musculoskeletal allotransplantion is the most common form of human tissue transplantation. Unlike solid organ transplants, bone allotransplants undergo rigorous processing and are considered non-viable tissue. In this study, we propose that donor genetic material may exist in circulation after bone allotransplantation. Fifty-one female patients who received bone allotransplants from male donors...

This paper develops enhanced material interface reconstruction techniques using genetic programming. Material interface reconstruction is the attempt to recreate high resolution material placement in computational meshes given only the percentages of materials at the coarser level of cells in the mesh. Previous techniques have been designed to create either accurate percentages or smooth interf...

Constitutive modeling of material behaviour is becoming increasingly important in prediction of possible failures in highly loaded engineering components, and consequently, optimization of their design. Damage occurrence and accumulation within the material are described in this paper by means of models of kinematic and isotropic hardening according to Chaboche material model. Since the materia...

Many genes of large double-stranded DNA viruses have a cellular origin, suggesting that host-to-virus horizontal transfer (HT) of DNA is recurrent. Yet, the frequency of these transfers has never been assessed in viral populations. Here we used ultra-deep DNA sequencing of 21 baculovirus populations extracted from two moth species to show that a large diversity of moth DNA sequences (n = 86) ca...

A general limitation in gene delivery is the cellular uptake in lager animals including humans. Several approaches have been tested including liposomes, micro-needles, in vivo electro-transfer, ballistic delivery, and needle-free delivery. All these techniques have individual limitations. One approach reproducibly delivering genetic material in muscle tissue in nonhuman primates is hydrodynamic...

We present an extension to the standard genetic algorithm (GA), which is based on concepts of genetic engineering. The motivation is to discover useful and harmful genetic materials and then execute an evolutionary process in such a way that the population becomes increasingly composed of useful genetic material and increasingly free of the harmful genetic material. Compared to the standard GA,...

Genetic programming (GP) is probably the most general approach from among evolutionary computation methods. The GP method is most often used for complex system modelling, but it can also be effectively used for the modelling of a relatively simple system, such as the systems described in our paper. In the paper a special genetic approach for the modelling of mechanical properties in formed mate...

The genus Saccharomyces consists of several species divided into the sensu stricto and the sensu lato groups. The genomes of these species differ in the number and organization of nuclear chromosomes and in the size and organization of mitochondrial DNA (mtDNA). In the present experiments we examined whether these yeasts can exchange DNA and thereby create novel combinations of genetic material...
