This meeting will return to the virtual-only format, via Zoom. The last two meetings this fall will be hybrid, with both a virtual and in-person component. We have a full schedule of three talks on 13 Oct. Details, including the Zoom link, have been sent to members. For non-members who wish to attend, please email Mong-Han Huang (mhhuang[at]umd.edu) for the Zoom link. Join us at 7:30 PM for socializing. The meeting will begin at 8 PM.
