Christodoulos Floudas and his students Stacy Janak and Martin Taylor have invented a mathematical formula that may transform the way that day-to-day work assignments are made across government and industry.
They didnt set out to accomplish such a broad goal. Initially they were simply attempting to solve a seemingly obscure problem: figuring out the best way for the National Science Foundation to efficiently and fairly assign funding proposals for review to its many reviewers.
NSF program managers Maria Burka and T.J. Mountziaris asked Floudas, a professor of chemical engineering at Princeton, to do just that. What he, Janak (a fifth-year graduate student) and Taylor (now an M.D./Ph.D. student at Johns Hopkins) came up with is an algorithm that within seconds can optimally assign 100 proposals to dozens of different reviewers.
Janak said that the difficult part of developing the model was distributing the proposals to reviewers in a fair way while taking into account the reviewers preferences for certain proposals over others.
To ensure that the model hewed to these restrictions, Janak had to use an unusual set of techniques called "logic inference principles." "Its not a methodology that a lot of people use or are aware of, but it was something that was necessary in this case to derive our model," she said.
Maria Burka of the NSF began using the algorithm on an experimental basis in April. "It works beautifully," she said.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
