Martin's conjecture, arithmetic equivalence, and countable Borel equivalence relations [PDF]
, 2011 There is a fascinating interplay and overlap between recursion theory and descriptive set theory. A particularly beautiful source of such interaction has been Martin's conjecture on Turing invariant functions.

Capturing a phylogenetic tree when the number of character states varies with the number of leaves [PDF]
, 2015 We show that for any two values $\alpha, \beta >0 $ for which $\alpha+\beta>1$ then there is a value $N$ so that for all $n \geq N$ the following holds.

Phylogenetic information complexity: Is testing a tree easier than finding it? [PDF]
, 2008 Phylogenetic trees describe the evolutionary history of a group of present-day species from a common ancestor. These trees are typically reconstructed from aligned DNA sequence data.

An Arrow-type result for inferring a species tree from gene trees [PDF]
, 2013 The reconstruction of a central tendency `species tree' from a large number of conflicting gene trees is a central problem in systematic biology. Moreover, it becomes particularly problematic when taxon coverage is patchy, so that not all taxa are ...

Corrosion of fasteners in furfurylated wood : final report after 9 years exposure outdoors [PDF]
, 2017 Corrosion of some common fastener materials – mild steel, stainless steel, zinc-coated steel, brass and Sanbond Z (nickel, zinc and chromate) coated steel – has been evaluated after nine years’ exposure outdoors in untreated Scots pine and furfurylated ...

A Hamiltonian treatment of stimulated Brillouin scattering in nanoscale integrated waveguides
, 2015 We present a multimode Hamiltonian formulation for the problem of opto-acoustic interactions in optical waveguides. We establish a Hamiltonian representation of the acoustic field and then introduce a full system with a simple opto-acoustic coupling that
