Meet USC: Admission Presentation, Campus Tour, & Engineering Talk
Mon, Mar 29, 2010
Viterbi School of Engineering Undergraduate Admission
University Calendar
This half day program is designed for prospective freshmen and family members. Meet USC includes an information session on the University and the Admission process; a student led walking tour of campus and a meeting with us in the Viterbi School. Meet USC is designed to answer all of your questions about USC, the application process and financial aid.Reservations are required for Meet USC. This program occurs twice, once at 9:00 a.m. and again at 1:00 p.m. Please visit http://www.usc.edu/admission/undergraduate/visit/meet_usc.html to check availability and make an appointment. Be sure to list an Engineering major as your "intended major" on the webform!

Math Colloq: Prof. Van Vu
Mon, Mar 29, 2010
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Prof. Van Vu (Rutgers University)Host: Center for Applied Mathematical Sciences ( http://www.usc.edu/dept/LAS/CAMS/Colloquia/3-29-2010.html )Talk Title:
Inverse Littlewood-Offord theory, Smooth Analysis and the Circular LawAbstract:
A corner stone of the theory of random matrices is Wigner's semi-circle law, obtained in the 1950s, which asserts that (after a proper normalization) the limiting distribution of the spectra of a random hermitian matrix with iid (upper diagonal) entries follows the semi-circle law. The non-hermitian case is the famous Circular Law Conjecture, which asserts that (after a proper
normalization) the limiting distribution of the spectra of a random matrix with iid entries is uniform in the unit circle.Despite several partial results (Ginibre-Mehta, Girko, Bai, Edelman, Gotze-Tykhomirov, Pan-Zhu etc) the conjecture remained open for more than 50 years. In 2008, T. Tao and I confirmed the conjecture in full generality. I am going to give an overview of this proof, which relies on rather surprising connections between various fields: combinatorics, probability and, particularly, theoretical computer science.

“Optical Interference for Nanoscale Biological Imaging and Detectionâ€Â
Professor M. Selim ÜnlüDepartment of Electrical and Computer EngineeringBoston University
We have utilized basic principles of optical interference and resonance in biological applicationsdemonstrating nanometer scale measurement capability in fluorescence microscopy and label-freesensing of protein binding and viruses in a high-throughput micro-array format.
We have developed a technique â€" spectral self-interference fluorescent microscopy (SSFM) â€" thattransforms the variation in emission intensity for different path lengths used in fluorescenceinterferometry to a variation in the intensity for different wavelengths in emission, encoding the high-resolution information in the emission spectrum. Using SSFM, we have estimated the shape of coiledsingle-stranded DNA, the average tilt of double-stranded DNA of different lengths, and the amount ofhybridization. The determination of DNA conformations on surfaces and hybridization behavior provideinformation required to move DNA interfacial applications forward and thus impact emerging clinical andbiotechnological fields. Recently, we have also applied SSFM to study the conformational changes ofpolymers and DNA-protein complexes. [1]
Direct monitoring of primary molecular binding interactions without the need for secondary reactantswould markedly simplify and expand applications of high-throughput label-free detection methods. We developed a simple interferometric technique â€" Spectral Reflectance Imaging Biosensor (SRIB) â€" that monitors the optical phase difference resulting from accumulated biomolecular mass. Dynamic measurements were made at ~10pg/mm2 sensitivity. We have also demonstrated simultaneous detection of antigens and antibodies in solution using corresponding probes on the SRIBsurface as well as label-free measurements of DNA hybridization kinetics.
