There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Part I
Sequential Monte Carlo and Protein Structure

The sequential Monte Carlo (SMC) methodology emerged in the fields of statistics and engineering has shown a great promise in solving a large class of highly complex inference and optimization problems. It is a family of Monte Carlo techniques that is based on the 'growth principle' in dealing with high dimensional complex systems. Specially, a high dimensional problem is decomposed into a sequence of low dimensional problems which forms a stochastic dynamic system. Weighted Monte Carlo samples are drawn from each of simpler component, and their combination then forms a Monte Carlo sample of the original system.
In this talk, we present SMC approaches in studying geometric properties of proteins. Specifically we introduce the general strategy of intermediate distribution design, look-ahead, multi-grid sampling and constraint enforcement. It is used to generate protein structures with certain geometric constraints, under a discrete off-lattice model.
Part II
Funding Opportunities for Statisticians at NSF
Rong Chen
National Science Foundation
In this talk, some of the funding opportunities for statisticians at NSF will be introduced, including the regular statistics program and programs in the mathematical priority area. Some tips on proposal writing will be offered. Suggestions, comments, and discussion on future direction of statistics are welcome.
