### Disparity and motion-in-depth processing in human visual cortex

Seminar | January 27 | 11:10 a.m.-12:30 p.m. | 489 Minor Hall

Anthony Norcia, Stanford University

Neuroscience Institute, Helen Wills

The lateral separation of the two eyes creates slight retinal image differences that provide binocular disparity and binocular motion cues that can be used to extract information about depth in the world. To gain insight about the neural mechanisms involved in processing these cues, we use cue-isolating stimulation techniques to study the dynamics of brain responses to changing disparity cues,...

### SEMM Seminar: Building a More Resilient San Francisco

Seminar | January 27 | 12-1 p.m. | Davis Hall, 502 Davis Hall

Danielle Hutchings Mieler, Office of Resilience and Capital Planning, City and County of San Francisco

Civil and Environmental Engineering (CEE)

Cities face a myriad challenges from rising seas, aging infrastructure, increasingly extreme weather, housing shortages and chronic homelessness. As we look to the future we ask, how will these challenges be exacerbated by a large earthquake? What will San Francisco be like with 160,000 new residents? How will climate change impact vulnerable populations? San Francisco is working to address the... More >

### Probabilistic Operator Algebra Seminar: Pseudospectral Shattering, the Sign Function, and Diagonalization in Nearly Matrix Multiplication Time I

Seminar | January 27 | 3-4 p.m. | 748 Evans Hall

Jorge Garza Vargas, UC Berkeley

In a recent joint work with J. Banks, A. Kulkarni and N. Srivastava, we have shown that on a high level, any efficient numerically stable matrix-multiplication algorithm can be turned into a diagonalization algorithm with the same properties. Quantitatively, our result significantly improves the best previously known provable running times of diagonalization algorithms. In this talk, which... More >

### Differential Geometry Seminar: Mean convex mean curvature flow with free boundary

Seminar | January 27 | 3:10-4 p.m. | 939 Evans Hall

Jonathan Zhu, Princeton

In the class of mean convex surfaces, the mean curvature flow provides a useful geometric tool, owing its power to the regularity and structure theory established by White and with subsequent developments by Haslhofer, Kleiner and Hershkovits. In joint work with Edelen, Haslhofer and Ivaki, we generalise this theory to the free boundary setting. There are significant analytic and geometric issues... More >

### Arithmetic Geometry and Number Theory RTG Seminar: Supersingular main conjectures, Sylvester's conjecture and Goldfeld's conjecture

Seminar | January 27 | 3:10-5 p.m. | 891 Evans Hall | Note change in location

Daniel Kriz, MIT

In this talk, I formulate and prove a new Rubin-type Iwasawa main conjecture for imaginary quadratic fields in which $p$ is inert or ramified, as well as a Perrin-Riou type Heegner point main conjecture for certain supersingular CM elliptic curves. These main conjectures and their proofs are related to $p$-adic L-functions that I have previously constructed, and have applications to two classical... More >

### A Life Course Framework for Improving the Lives of Boys and Young Men of Color

Panel Discussion | January 27 | 4-5:30 p.m. | 116 Haviland Hall

This presentation provides a holistic analytic framework and a strategic canvas for improving the life outcomes for males of color.

### Compact accelerators and photon sources using laser-driven plasma acceleration

Colloquium | January 27 | 4-5 p.m. | 3105 Etcheverry Hall

Abstract: Plasma waves can support extremely large accelerating fields, several orders of magnitude greater than conventional accelerators, and, hence, provide a compact method of generating energetic charged particle beams. Plasma waves suitable for particle acceleration may be resonantly excited using the radiation pressure from intense, high-power, ultrashort laser pulses. Laser-driven plasma... More >

### Illuminating the biochemistry of zinc and RNA in live cells

Seminar | January 27 | 4-5 p.m. | 106 Stanley Hall

Amy Palmer, University of Colorado Boulder

There are over two thousand proteins encoded by the human genome that are predicted to bind zinc, where zinc binding is predicted to be essential for function. At the cellular level zinc is important for DNA synthesis, cell proliferation, differentiation, and apoptosis. Given the importance of Zn2+ in cell biology and human health, it is astounding that we still don’t understand the mechanisms of... More >

### Analysis and PDE Seminar: Box condition versus Chang–Fefferman condition for weighted multi-parameter paraproducts.

Seminar | January 27 | 4:10-5 p.m. | 939 Evans Hall

Alexander Volberg, Michigan State University

Paraproducts are building blocks of many singular integral operators and the main instrument in proving “Leibniz rule” for fractional derivatives (Kato–Ponce). Also multi-parameter paraproducts appear naturally in questions of embedding of spaces of analytic functions in polydisc into Lebesgues spaces with respect to a measure in the polydisc. The latter problem (without loss of... More >

### Thematic Seminar: K-stability and moduli spaces of Fano varieties

Seminar | January 27 | 4:10-5 p.m. | 740 Evans Hall

Yuchen Liu, Yale

Fano varieties are positively curved algebraic varieties which form one of the three building blocks in the classification. Unlike the case of negatively curved varieties, moduli spaces of Fano varieties (even smooth ones) can fail to be Hausdorff. K-stability was originally invented as an algebro-geometric notion characterizing the existence of Kähler-Einstein metrics on Fano varieties.... More >

### Job Market Seminar: "Selling Consumer Data for Profit: Optimal Market-Segmentation Design and its Consequences"

### Quantum supremacy using a programmable superconducting processor

Colloquium | January 27 | 4:15-5:15 p.m. | LeConte Hall, 1 LeConte Hall

John Martinis, UC Santa Barbara / Google

The promise of quantum computers is that certain computational tasks might be executed exponentially faster on a quantum processor than on a classical processor. A fundamental challenge is to build a high-fidelity processor capable of running quantum algorithms in an exponentially large computational space. Here we report the use of a processor with programmable superconducting qubits to create... More >

### ATC Lecture — Amy LaViers, "Dancing with Robots: Expressivity in Natural and Artificial Systems"

Colloquium | January 27 | 6:30-8 p.m. | Berkeley Art Museum and Pacific Film Archive, Osher Theater

Amy LaViers, Robotics, Automation, and Dance (RAD) Lab

Center for New Media, CITRIS and the Banatao Institute, Department of Theater, Dance, and Performance Studies, Arts + Design

Movement seems to encode information. How does this work? We know that animals, including humans, use the motion of counterparts to produce coordinated, social behaviors. But how do we resolve the discrete measures of communication and information theory with the continuous laws of motion and mechanics? Answering these questions is critical to developing expressive robotic systems that integrate... More >
