The endoplasmic reticulum (ER) is a complex dynamic organelle which reaches into the cellular compartments of a neuron, including dendritic spines. For this talk we will explain the model equations that govern the ion exchange mechanisms located on the plasma membrane (PM) of the neuron and the exchange mechanisms located on ER membrane. We will also demonstrate for different spine-dendrite morphologies, modifying calcium influx rate at the synapse of the spine, and modifying the density of receptors on the ER membrane affects calcium propagation through the spine-dendrite.

Abstract: In joint work with Max Lahn, Marissa Loving, and Sunny Yang Xiao, we showed recently that a regular cover of surfaces is determined by which closed curves on the base surface admit simple elevations to the cover. This theorem was motivated by a question related to pairs of isospectral hyperbolic surfaces arising from Sunada’s construction, but the assumption of regularity prevented the result from being applicable in that context. In joint work with Max, Marissa, and Nick Miller, we are now able to drop this assumption. We’ll discuss the motivation, some of the ideas used in the arguments, and where there is still work to do.

Abstract: Since the discovery of Shor's algorithm in 1994, quantum computing has been advertised as the next big revolution in computer science as well as in quantum chemistry and cryptography. In this talk, I will introduce Grover's algorithm and its extension as a search algorithm on general graphs. I will discuss ways in which the promise of quantum computing has been exaggerated, and ways in which we may expect to see substantive contributions from the field to our understanding of complexity theory. Finally, I will demonstrate some recent results from simulations of quantum search on random graphs.
