### Teaching in Summer Workshop

Workshop | April 30 | 10 a.m.-1 p.m. | Dwinelle Hall, Academic Innovation Studio (117)

American Cultures

Please join us for a discussion of some of the best approaches to teaching during the summer at UC Berkeley. Among the topics, we will discuss are strategies for managing extended summer class time, what to expect from summer student enrollment, the specifics of the AC requirement, and teaching to issues of racial and economic justice in diverse classrooms.

by April 30.

### The neural circuits of the fly's olfactory memory

Seminar | April 30 | 2-3 p.m. | 540 Cory Hall

Lou Scheffer, Howard Hughes Medical Institute

The fruit fly Drosophila will avoid odors previously associated with unpleasant experiences, and pursue odors previously associated with rewards. It has long been known that the seat of this associative learning is the Mushroom Body, a particular compartment of the fly's brain. Using a combination of genetic methods, behavioral experiments, electrophysiology, and circuit reconstruction (through...   More >

### Differential Geometry Seminar: Higher-order estimates for collapsing Calabi-Yau metrics

Seminar | April 30 | 2:10-3 p.m. | 939 Evans Hall

Hans-Joachim Hein, Fordham University

Department of Mathematics

Consider a compact Calabi-Yau manifold $$X$$ with a holomorphic vibration $$F: X \rightarrow B$$ over some base $$B$$, together with a "collapsing" path of Kahler classes of the form $$[F^*\omega _B] + t [\omega _X]$$ for $$t \in (0,1]$$. Understanding the limiting behavior as $$t \rightarrow 0$$ of the Ricci-flat Kahler forms representing these classes is a basic problem in geometric analysis...   More >

### Applied Math Seminar: Smoothing techniques for risk-averse PDE-constrained optimization

Seminar | April 30 | 3-4 p.m. | 959 Evans Hall

Drew Kouri, Sandia National Laboratories

Department of Mathematics

Many science and engineering applications necessitate the optimal control or design of systems described by partial differential equations (PDEs) with uncertain inputs such as coefficients, boundary conditions and initial conditions. In this talk, I formulate such problems as risk-averse optimization problems in Banach space. For many popular measures of risk such as coherent risk measures, the...   More >

### BLISS Seminar: Phase Transitions in Generalized Linear Models

Seminar | April 30 | 3-4 p.m. | 540 Cory Hall

Leo Miolane, INRIA

We consider generalized linear models (GLMs) where an unknown $n$-dimensional signal vector is observed through the application of a random matrix and a non-linear (possibly probabilistic) componentwise output function.

### Arithmetic Geometry and Number Theory RTG Seminar: Constancy of generalized Hodge-Tate weights of a p-adic local system

Seminar | April 30 | 3:10-5 p.m. | 748 Evans Hall

Koji Shimizu, Harvard University

Department of Mathematics

Sen attached to each p-adic Galois representation of a p-adic field a multiset of numbers called generalized Hodge-Tate weights. In this talk, we regard a p-adic local system on a rigid analytic variety as a geometric family of Galois representations and show that the multiset of generalized Hodge-Tate weights of the local system is constant. The pretalk is designed to be a quick introduction to...   More >

Professor Avraham Shtub holds the Stephen and Sharon Seiden Chair in Project Management. He was a faculty member of the department of Industrial Engineering at Tel Aviv University from 1984 to 1998 where he also served as a chairman of the department (1993-1996)...   More >

### The Next Generation of Brain-Computer Interfaces: Responding Implicitly to Learners' Cognitive State

Colloquium | April 30 | 4-5:30 p.m. | 2515 Tolman Hall

Beste Yuksel, University of San Francisco

The human and computer are both complex machines, capable of sophisticated functions, yet there is a very narrow bandwidth of communication between them. A new generation of brain computer interfaces (BCIs) are currently being developed that can increase this communication bandwidth by passively detecting learners' cognitive state and responding appropriately in real-time. In this talk, I present...   More >

### Dissertation talk: Classical delegation and verification of quantum computations

Seminar | April 30 | 4-5 p.m. | 540AB Cory Hall

Due to recent advances in quantum computing, two related open questions have become increasingly important. First, can a classical computer delegate a quantum computation without compromising privacy? Next, is it possible for a classical computer to verify the result of a quantum computation? In this talk, we present methods allowing a classical computer to achieve both of these cryptographic...   More >
