Conference/Symposium | February 3 – 5, 2017 every day | Dwinelle Hall
Workshop | January 30 – February 3, 2017 every day | Calvin Laboratory (Simons Institute for the Theory of Computing)
This workshop will focus on explicit constructions of graphs and functions with pseudorandom properties. There will be two main themes related to each object in the title. For expanders, these will be proofs of existence of expander graphs using lifts, a la Bilu-Linial and Marcus-Spielman-Srivastava, and the possibility of using the method to obtain explicit constructions of Ramanujan expanders...

Essig Brunch: Dr. Javier Ceja Navarro, Lawrence Berkeley Lab: Arthropod-microbiome interactions and their role in the host’s environmental adaptation
Seminar | February 3 | 10-11 a.m. | 1101 Valley Life Sciences Building
Dr. Javier Ceja Navarro, Postdoctoral Researcher, Lawrence Berkeley Lab
The Entomology Students' Organization is pleased to present the Essig Brunch, UC Berkeley's only entomology-themed seminar series. Join us once a week to hear about exciting new research on a broad range of insect-related topics, from evolution to conservation to ecology to pest management, and much more. Refreshments are provided and all are welcome!
Seminar | February 3 | 11 a.m.-12:30 p.m. | 5101 Tolman Hall
Dan Mirman, University of Alabama at Birmingham
Representing concepts in terms of semantic features, like < has 4 legs > or < is yellow >, has driven major advances in understanding semantic cognition, integrating behavioral, neural, and computational research. Feature-based approaches are very good at capturing taxonomic relations such as DOG -- BEAR, but it is less clear how they could capture thematic relations such as DOG -- LEASH, which... More >

Solid State Technology and Devices Seminar: “Phonon Lasing” as a Mechanism for Velocity Saturation in GaN HEMT
Seminar | February 3 | 1-2 p.m. | Cory Hall, 521 - The Hogan Room
Jacob B Khurgin, Professor, Johns Hopkins University, Baltimore, MD, United States
Velocity saturation plays the most important role in determining operational characteristics of field effect transistors. While the causes of velocity saturation in GaAs and InP high electron mobility transistors (HEMTs) are well known, the cause of saturation has not been indisputably determined for the GaN based HEMTs. Moreover, the saturation velocity in GaN HEMT has been shown... More >
Conference/Symposium | February 3 | 1-6:30 p.m. | 180 Doe Library
Urbanization, globalization, and climate change have had a powerful effect on the ways Mongolians and Inner Mongolians relate to their environment, and this is transforming many of their cultural forms. This conference seeks to increase awareness of the relationships been musical expression and the ecological, economic and political issues impacting residents in different ethnic groups in both...

Trust in basic democratic institutions is dropping and has been for years. Trust in facts, data, and science also seem to be eroding in what is being called a post-fact world.
What is going on? And what can be done about it?
Please join us for a mini unconference to discuss ways academics and data scientists might constructively improve our democratic infrastructure. This will be an open... More >
Seminar | February 3 | 2-3 p.m. | 390 Hearst Memorial Mining Building
Prof. Surjeet Rajendran, UC Berkeley, Physics
We know that there is five times more dark matter in the universe than the normal (baryonic) matter that we are made out of. But, other than its existence we know very little about its properties.
What is its mass? How does it interact with baryonic matter? One way to identify these properties is to make guesses about what the dark matter could be. We can then build a sensitive instrument... More >
Seminar | February 3 | 2-4 p.m. | 775B Tan Hall
Dr. Wei Cai, Stanford University
Dislocation nucleation is essential to our understanding of plastic deformation, ductility and mechanical strength of crystalline materials. Molecular dynamics simulation has played an important role in uncovering the fundamental mechanisms of dislocation nucleation, but its limited time scale remains a significant challenge for studying nucleation at experimentally relevant conditions. Here we... More >
Seminar | February 3 | 2:10-3:30 p.m. | 891 Evans Hall
Fraydoun Rezakhanlou, UC Berkeley
In this talk I show how a random translation of a Hamiltonian vector field improves the regularity of its flow.
On Fridays at 3:00 during the semester, the CMES hosts an informal weekly coffee hour and guided discussion of current events in the Middle East and North Africa, open to all and free of charge.
Seminar | February 3 | 3:10-5 p.m. | 107 South Hall
What if we take the central concept of information science and see where it leads?
Seminar | February 3 | 4-5 p.m. | Pitzer Auditorium, 120 Latimer Hall
Colloquium | February 3 | 4:30 p.m. | 125 Morrison Hall
Carolyn Abbate (Harvard University), "Primordial Microphonics"
Carolyn Abbates work centers on opera history, music and philosophy, ephemeral art, and on film and sound studies. Her writings have been translated into several languages, and she herself is a translator (most recently, of Vladimir Jankélévitchs La musique et lineffable). Current research projects include: operetta and ethical... More >
