Solid State Technology and Devices Seminar

521 Hogan Room Cory Hall
  • Monica Allen, Stanford University
Although the wavelength of microwaves far exceeds the nanoscale, it is possible to use an RF sensor to perform nanoscale imaging by confining electromagnetic fields to small spatial dimensions. In this talk, I will discuss microwave impedance microscopy (MIM), a near-field imaging tool that spatially visualizes the local conductivity and dielectric constant of a material with nanoscale precision....

Bioelectronic Noses for Odorants and Airborne Pathogen

247 Cory Hall
  • Prof. Seunghun Hong, Seoul National University, Applied Physics
Recent progress in nanotechnology allows one to combine nanoscale devices with bio-molecules to build versatile nano-bio devices with interesting functionalities. One example can be a bioelectronic nose device to smell specific odorants just like human noses. In this work, we coated olfactory receptor proteins on carbon nanotube-based transistors to build bio-electronic noses which can...

Ultra High-Field MRI - Open questions in engineering and multiphysics

Wozniak Lounge (430 Soda Hall) Soda Hall
  • Simone Angela Winkler, Staff Research Associate, Stanford University
Magnetic Resonance Imaging (MRI) has emerged as one of the most powerful and informative diagnostic tools in modern medicine. While most clinical MR studies use magnetic field strengths of 1.5T or 3T, leading research is pushing these magnetic field strengths to 7T and beyond.

Barna Saha - Efficient Fine-Grained Algorithms

3108 Etcheverry Hall
  • Barna Saha, University of Massachusetts Amherst
Abstract: One of the greatest successes of computational complexity theory is the classification of countless fundamental computational problems into polynomial-time and NP-hard ones, two classes that are often referred to as tractable and intractable, respectively. However, this crude distinction of algorithmic efficiency is clearly insufficient when handling today's large scale of data. We need...

Dr. Mingfu Shao, Department of Computational Biology, Carnegie Mellon University

HP Auditorium 306 Soda Hall
Title: Abstract: I will present modeling and algorithmic designs for two challenging problems in biology and argue that efficient computational methods enable significant advances in our understanding of cell machinery and genome evolution. The first problem is the assembly of full-length transcripts -- the collection of expressed gene products in cells -- from noisy and highly...

GraphXD Seminar: Vector Representations of Graphs and the Maximum Cut Problem

1011 Evans Hall
  • David P. Williamson, Operations Research and Information Engineering, Cornell University
In this talk, I will look at a classical problem from graph theory of finding a large cut in a graph. We’ll start with a 1967 result of Erdős that showed that picking a random partition of the graph finds a cut that is at least half the largest possible cut. We’ll then describe a result due to Goemans and myself from 1995 that shows that by representing the graph as a set of vectors, one per...
