Civil and Environmental Engineering Department Seminar: Data-assisted high-fidelity modeling for systems design and monitoring

Seminar | March 4 | 10-11 a.m. | 542 Davis Hall

 Audrey Olivier

 Civil and Environmental Engineering (CEE)

Increased availability of measured data has recently generated tremendous interest in the development of methods to learn from data. In parallel, engineers have a long history of building high-fidelity physics- based models that allow us to model the behavior of highly complex systems. This talk aims at presenting some of the exciting research opportunities that arise.

Katharina Foote's Abstract
Structure and function in retinitis pigmentosa patients with mutations in RHO vs. RPGR

Retinitis pigmentosa (RP) causes slow, progressive, relentless death of photoreceptors. In order to gain insight on how cone survival differs between different mutations affecting rods vs. affecting rods and cones, we measured cone structure and function in patients with mutations...   More >

Instabilities and Phase Transitions in Multiphase Flow Through Porous Media: Fluids Seminar

Seminar | March 4 | 12-1 p.m. | 3110 Etcheverry Hall

 Xiaojing (Ruby) Fu, Miller Fellow, Department of Earth and Planetary Sciences, University of California, Berkeley

 Department of Mechanical Engineering (ME)

Flow and transport through porous media is ubiquitous in nature. They are key processes behind subsurface resources such as oil and gas, geothermal energy, and groundwater. They also mediate corrosion and ageing of porous engineering materials as well as geohazards such as landslides, volcanic eruptions and earthquakes. Central to many of these processes is the strong coupling between porous...   More >

Maladaptive responding to the distress of others: Insights from developmental neuroscience

Colloquium | March 4 | 12:10-1:30 p.m. | 1102 Berkeley Way West

 Kalina Michalska, University of California, Riverside

 Department of Psychology

A fundamental question in developmental affective science is how children come to understand the emotions of others when deciding how to behave towards them. One consequential domain of such an ability is responding to others’ distress with empathy and kindness. In this talk, I will explore the neurobiological and social factors that lead some children to respond maladaptively to the distress of...   More >

Combinatorics Seminar: On statistic of irreducible components

Seminar | March 4 | 12:10-1 p.m. | 939 Evans Hall

 Nicolai Reshetikhin, UC Berkeley

 Department of Mathematics

For finite dimensional representations $V_1, \dots , V_m$ of a simple finite dimensional Lie algebra $\mathfrak g$ consider the tensor product $W=\otimes _{I=1}^m V_i^{\otimes N_i}$. The first result, which will be presented in the talk, is the asymptotic of the multiplicity of an irreducible representation $V_\lambda $ with the highest weight λ in this tensor product when $N_i=\tau _i/\epsilon...   More >

Political Economy Seminar

Seminar | March 4 | 12:30-2 p.m. | 223 Moses Hall

Carbopalladation Cascades – Not only syn, but also anti

Seminar | March 4 | 1:30-2:30 p.m. | 775B Tan Hall

 Prof. Daniel Werz, Technical University Braunschweig

 College of Chemistry

A characteristic feature of carbopalladation reactions is the syn-attack of the organopalladium species LnX[Pd]-R on the reacting π-system. Such a step results in compounds bearing Pd and R on the same side of the originating alkene moiety. Embedded into longer domino sequences complex structures are efficiently obtained by
a repetition of this syn-carbopalladation step. In this way, linear...   More >

Arithmetic Geometry and Number Theory RTG Seminar: Arithmetic Siegel-Weil formula for orthogonal Shimura varieties

Seminar | March 4 | 3-5 p.m. | 748 Evans Hall

 Tonghai Yang, University of Wisconsin

 Department of Mathematics

After reviewing Siegel-Weil formula and progress on arithmetic Siegel-Weil formula, I will talk about my new work with Jan Bruinier on this subject. Let $L$ be an integral lattice of signature $(n, 2)$ over $\mathbb Q$, and let $T$ be a non-singular symmetric integral matrix. Associated to it are two objects. One is the $T$-th Fourier coefficient $a(T)$ of the derivative of some `incoherent’...   More >

Remaking Urban Landscape in China’s Large Cities: State-Society Nexus and the Reproduction of Space amidst Accelerate Urbanization

Colloquium | March 4 | 4 p.m. | 180 Doe Library

 George C.S. Lin, Chair Professor of Geography, Department of Geography, The University of Hong Kong

 You-tien Hsing, Professor of Geography, UC Berkeley

 Center for Chinese Studies (CCS), Center of Global Metropolitan Studies

Phenomenal transformation of the landscape in Chinese cities has been conventionally understood as the spatial outcome of the reformation of state-market relations. The current urban landscape observable today is described as a juxtaposition of two elements, namely the legacy of the socialist city and the newly emerged space of marketization. This research identifies a new wave of urbanization in...   More >

PHYSICS/SQB Colloquia: "Exploring Embryonic Patterning With Colonies Of Human Embryonic Stem Cells"

Seminar | March 4 | 4-5 p.m. | 1 LeConte Hall

 Eric Siggia, The Rockefeller University

 College of Chemistry, Department of Physics

Embryology at the beginning of the 21st century finds itself in a situation similar to neurobiology; the behavior of the component pieces is understood in some detail, but how they self-assemble to become life is still very hazy. There are 100’s of molecules that enable cell communication and genetics defines their function by classifying aberrant embryos at a suitable intermediate stage of...   More >

Science in the Schoolyards of Detroit, Cairo, and Philadelphia: What are the seven Ss of success?

Colloquium | March 4 | 4-5:30 p.m. | Berkeley Way West, Room 1215, 2121 Berkeley Way, Berkeley, CA 94720

 Nancy Butler Songer, Drexel University, School of Education

 Graduate School of Education

This talk will present three stories and empirical research results associated with middle and high school-based systemic reform with investigation and design projects as the focus of the reform. Where was systemic change realized, and where did it falter? Drawing from these research-based stories, what are the seven Ss of secondary science success?

In this talk, I will discuss my work in reconstructing 3D non-rigid, deformable objects such as humans and animals from everyday photographs and video, and show how such systems can be used to train a simulated character to learn to act by watching YouTube videos.

Seminar 208, Microeconomic Theory: Complementary Information and Learning Traps

Seminar | March 4 | 4:10-5:30 p.m. | 639 Evans Field

 Annie Liang, University of Pennsylvania

 Department of Economics

We develop a model of social learning from complementary information: Shortlived agents sequentially choose from a large set of (flexibly correlated) information sources for prediction of an unknown state, and information is passed down across periods. Will the community collectively acquire the best kinds of information? Longrun outcomes fall into one of two cases: (1) efficient information...   More >

Analysis and PDE Seminar: Dispersive decay of small data solutions for the KdV equation

Seminar | March 4 | 4:10-5 p.m. | 740 Evans Hall

 Mihaela Ifrim, UW Madison

 Department of Mathematics

We consider the Korteweg-de Vries (KdV) equation, and prove that small localized data yields solutions which have dispersive decay on a quartic time-scale. This result is optimal, in view of the emergence of solitons at quartic time, as predicted by inverse scattering theory. Joint work with Herbert Koch and Daniel Tataru.

Nnedi Okorafor in Conversation with Donna Jones

Presentation | March 4 | 6:30 p.m. |  Berkeley Art Museum and Pacific Film Archive

 Berkeley Art Museum and Pacific Film Archive

“Nature is the greatest artist and scientist,” writes Nnedi Okorafor, an award-winning author of African-based science fiction, fantasy, and magical realism for both children and adults. “If we human beings, with our rather brilliant, often flawed, sometimes evil creativity, joined forces with our creator (nature), as opposed to trying to control it and treat it like our slave, imagine the...   More >
