Ellingson, Drew | Bitangent lines to planar quartic curves in algebraic and tropical geometry | Bitangents are lines which are tangent to a curve at two points. The bitangents of a classical quartic are well understood, and a result originally due to Cayley tells us that there are always precisely 28 bitangents to a generic quartic plane curve. When looking at Tropical Geometry, the situation ... | Tropical geometry; Curves, Quartic; Curves, Algebraic; Bitangents | 2015-04 |

Beams, Alexander | Implications of antibiotic use for co-infections when a fitness trade-off for resistance is present | How much does indiscriminate antibiotic use promote the spread of antibiotic-resistant infections in a population? Assuming a fitness trade-off for resistance exists, it is possible for an antibiotic-vulnerable strain to outlast a resistant type within an untreated host carrying both. That means pru... | Drug resistance in microorganisms -- Mathematical models Co-infections | 2015 |

Allam, Jeremy | Low-energy satellite transfer from Earth to Mars | A new type of satellite transfer that uses half the amount of fuel as conventional transfers has been discovered. This transfer, called a low-energy transfer, proved to work in 1991 when a Japanese satellite successfully went in orbit around the moon using this technique. Since then, more research h... | Space vehicles -- Dynamics -- Mathematics Space flight to Mars -- Mathematics | 2015-04 |

Tuft, Marie | Quantitative analysis of virus trafficking in a biological cell | Virus replication is a complex process that is important to understand. If a virus is to successfully infect a host cell it must travel from the cell wall to the nucleus by hijacking that cell's existing transport system of microtubules. This motion occurs as two iterated steps: passive diffusion th... | Viruses -- Reproduction -- Mathematical models; Virus trafficking | 2015-05 |
