Descent with modification (Darwin, 1859) overwhelmingly occurs through the process of natural selection on genetically variable traits. Following deglaciation in the Pleistocene, morphologically conservative marine stickleback ...

While wildfire is globally most common in the savanna-grassland ecotone, the flammability of coastal temperate rainforests is considered low and little is known regarding historic fire activity. Reconstructing historical ...

A 2-dipath k-colouring of an oriented graph G is an assignment of k colours, 1,2, . . . , k, to the vertices of G such that vertices joined by a directed path of length two are assigned different colours. The 2-dipath ...

In Pacific North America, a substantial amount of the streamflow available during the dry summer months originates from melting mountain snowpacks. Since the start of the twenty-first century, these mountain snowpacks have ...

This dissertation presents results from a complex seismic study using Ocean Bot¬tom Seismometers (OBS) conducted at a site of deep sea gas hydrate occurrence. The site is located on the accretionary margin of the northern ...

This thesis presents an algorithm for producing 4–manifold triangulations with boundary an arbitrary orientable, closed, triangulated 3–manifold. The research is an extension of Costantino and Thurston’s work on determining ...

Alzheimer’s disease (AD), a progressive neurodegenerative disorder, is becoming increasingly prevalent in aging populations. It is characterized by the buildup of amyloid beta plaques and neurofibrillary tangles containing ...

The development of large dense arrays of smaller antennas and moderate-sized antennas equipped with multi-beam arrays in the next generation of radio telescopes, such as the square kilometre array (SKA), is making 3D ...

1D stellar evolution and nucleosynthesis simulations have traditionally modeled the mixing within convection zones as a diffusive process. The fluids within a convection zone are advecting and do not diffuse. However the ...

In recent decades, the accessibility of nuclear physics has been greatly improved due to the advent of modern supercomputers, as well as theoretical developments in effective field theory and ab initio (first--principles) ...
