Development of a Calculator For Medical Student Residency Applications
This poster describes an attempt to create an evidence-based approach to advising medical students with regard to the number of family medicine residency programs to which they need to apply
A duality model of TCP and queue management algorithms
We propose a duality model of end-to-end congestion control and apply it to understanding the equilibrium properties of TCP and active queue management schemes. The basic idea is to regard source rates as primal variables and congestion measures as dual variables, and congestion control as a distributed primal-dual algorithm over the Internet to maximize aggregate utility subject to capacity constraints. The primal iteration is carried out by TCP algorithms such as Reno or Vegas, and the dual iteration is carried out by queue management algorithms such as DropTail, RED or REM. We present these algorithms and their generalizations, derive their utility functions, and study their interaction
Convex Relaxation of Optimal Power Flow, Part II: Exactness
This tutorial summarizes recent advances in the convex relaxation of the
optimal power flow (OPF) problem, focusing on structural properties rather than
algorithms. Part I presents two power flow models, formulates OPF and their
relaxations in each model, and proves equivalence relations among them. Part II
presents sufficient conditions under which the convex relaxations are exact.Comment: Citation: IEEE Transactions on Control of Network Systems, June 2014.
This is an extended version with Appendex VI that proves the main results in
this tutoria
University-Based Forestry Research and The Little Red Hen
Universities have three basic mission areas: service, teaching, and research. Through the service mission, many forest landowners participate in forestry extension programs and use university-based out reach materials and resources. Many forest landowners also recognize the teaching mission of universities by interacting regularly with forestry professionals who were trained through academic programs accredited by the Society of American Foresters. These two mission areas, service and teaching, have been and continue to be relevant to millions of forest landowners across the nation.
But what about university-based forestry research? As a forestry dean and as current president of the National Association of University Forest Resources Programs, and (just as importantly) as a forest landowner, I\u27d like to address three key questions about forestry research, including what this has to do with The Little Red Hen
Effect of Landau Level Mixing on Braiding Statistics
We examine the effect of Landau level mixing on the braiding statistics of
quasiparticles of abelian and nonabelian quantum Hall states. While path
dependent geometric phases can perturb the abelian part of the statistics, we
find that the nonabelian properties remain unchanged to an accuracy that is
exponentially small in the distance between quasiparticles.Comment: 4 page
Convex Relaxation of Optimal Power Flow, Part I: Formulations and Equivalence
This tutorial summarizes recent advances in the convex relaxation of the
optimal power flow (OPF) problem, focusing on structural properties rather than
algorithms. Part I presents two power flow models, formulates OPF and their
relaxations in each model, and proves equivalence relations among them. Part II
presents sufficient conditions under which the convex relaxations are exact.Comment: Citation: IEEE Transactions on Control of Network Systems,

IX that provide some mathematical preliminaries and proofs of the main
