General Information

The workshop will concentrate on primary topics of research in three of the SAMSI working groups in 2009-10. As well as talks by invited speakers, working groups will present results and work-in-progress with the aim of generating interaction with the guests.

Molecular motors are biological molecular machines that convert energy into motion, producing movement in living organisms, operating at a scale where thermal noise is significant. Because motor events are stochastic, they may be modeled in terms of random walk or Markov processes. An active topic is the stochastic dynamics of such models.

Several well-known neuron models are being studied with the aim of comparing the stochastic dynamics of the models. A fundamental question is, in what cases the transition from firing to quiescence and back is governed by boundary crossing times of a stochastic process, as opposed to large deviation times. The larger question for stochastic dynamics is the nature of transition times between domains of attraction of locally stable configurations.

Epidemics have been defined on networks in various ways. One approach is to fix a network and define a version of a classical mean field epidemic model on that network by specializing the interaction equations to specific local interactions. The challenge is to devise models where solutions, or at least some of their properties, are accessible.

Organizers: Priscilla Greenwood (ASU), John Fricks (Penn State), Lea Popovic (Concordia), Scott Schmidler (Duke)

Application

The application/registration deadline is March 26, 2010. Note, however, that workshop capacity might be reached before this deadline. Also, any application that requests support for expenses should typically be submitted at least 6 weeks in advance of the workshop.

To apply to attend the workshop, please fill out the ON-LINE APPLICATION FORM , and then click the SUBMIT APPLICATION button. All items are required. Following submission, a confirmation of your application will be displayed: print a copy for your records.

In order to ensure your application is correct, we ask that you:

refresh/reload the application/registration page to ensure you have all updates
type in your information (cutting and pasting will distort the information we receive)
make any clarifications/corrections, in the Special Requests section
click the submit button only once

Please make reservations at the Radisson RTP as soon as possible. The SAMSI room block and rate ($109) is effective until March 26, 2010. After this date, there is no guarantee a room will be available. If you have a change in plans, individual room reservations must be cancelled 72 hours prior to arrival. Check-in is at 3:00 PM; check-out is 12:00 noon.
