Abstract

   In this talk, I’d like to present some research topics in biology. The first topic is to study the invading phenomenon of an alien specie to the habitat of two aboriginal species by traveling front connecting semi-co-existence state and co-existence state. Based on an application of Schauder’s fixed point theorem with the help of (generalized) upper-lower-solutions, we characterize the minimal wave speed of this invading process. New form of upper-lower-solutions are constructed to derive the existence of traveling waves for all admissible speeds.

  The second topic is to study the method to predict the mutation of protein sequence. It is helpful for developing the vaccine if the position of mutation is predicted. With the applications of deep neural network in bioinformatics, some experiments show that we can use generative adver-sarial Network (GAN) to train a machine to predict the protein mutation, e.g., MutaGAN. In our project, we want to modify the generator in Mu-taGAN by using attention model. Since attention model is applied suc-cessfully in machine translation which is based on a sequence to sequence structure. It look forward to see if MutaGAN with attention model will get a better performance.
