Time: 3:30 - 4:30pm.
SPEAKERS: Drs. Milena Cuellar (MEC) and Preethi Radhakrishnan (NS); LaGuardia C. C.

Topic1: "The Scientific Method and Reconstruction of Chaotic Attractors from Partial Observations."
Topic2: "The Buzzed Fly: Effects of Alcohol Consumption on Fertility in D. melanogaster (common fruit fly)."

Abstract 1: Scientists spend most of their time and energy observing and describing natural (physical) phenomena of their interest. Then a model is developed to "mimic" the dynamical temporal evolution of such phenomena. This talk briefly presents the basics on how we apply the scientific method in this situation for incomplete and partial observations and how we use a model to mimic the observed behavior. In particular, we present results for the Lorenz 1963 chaotic model using a nonlinear dynamical and geometrical approach to identify and select the best model to predict the future of the system. Chaotic models are especially useful to model and represent nonlinear and complex natural behaviors interest like the number of spots in the face of the Sun, a climatological system or the heat convention in the atmosphere, etc.
Abstract 2: Alcohol (ethanol) addiction is a common affliction with a strong genetic component. Ethanol acts on multiple neural pathways in order to produce heightened behavioral responses. The adaptive responses of fruit flies, Drosophila melanogaster, have been shown to be strikingly similar to those of mammalian systems such as rodents and human. This talk will briefly discusses the study that have used D. melanogaster as a model to explore the relationship between extensive alcohol feeding and its effect on mate choice. It was found that D. melanogaster showed consisted preference for ethanol food over non-ethanol food. The consumction of ethanol was also found to heighten courtship behavior and downregulate fertility thereby reinforcing the important link between ethanol consumption and reproductive health.
