### Integration of guided experiential skill application into attention regulation training yields generalized improvements in cognitive functioning

Seminar | January 22 | 12-1:30 p.m. | 489 Minor Hall

Sahar Yousef, Silver Lab

Neuroscience Institute, Helen Wills

Improvement of cognitive function is of great value to many aspects of society. However, identifying robust procedures for training cognitive processes in a generalizable way remains elusive. Here we present a novel attention regulation training paradigm that incorporates skill application in multiple learning environments. We hypothesized that our training procedure would enhance...

### Combinatorics Seminar: Combinatorics of the Selberg integral

Seminar | January 22 | 12-1 p.m. | 939 Evans Hall

Jang Soo Kim, Sungkyunkwan University

In 1944, Selberg evaluated a multivariate integral, which generalizes Euler's beta integral. In 1980, Askey conjectured a $q$-integral version of the the Selberg integral, which was proved independently by Habsieger and Kadell in 1988. In this talk, we focus on the combinatorial aspects of the Selberg integral. First, we review the following fact observed by Igor Pak: evaluating the Selberg... More >

Seminar | January 22 | 12:30-2 p.m. | C125 Haas School of Business

Anastassia Fedyk, Harvard

Joint with Haas Finance Seminar

### Data Driven: Truckers and the New Workplace Surveillance

Colloquium | January 22 | 2-3:30 p.m. | 820 Barrows Hall

Karen Levy, Assistant Professor of Information Science, Associated Faculty at Cornell Law School, Cornell University

This talk examines how electronic monitoring systems in the U.S. trucking industry are used to compel truckers' compliance with legal and organizational rules. New regulations will require truckers' time to be monitored by digital systems, hard-wired into the trucks themselves, which remove much of the flexibility on which truckers have historically relied.

### Probabilistic Operator Algebra Seminar: Boolean probability basics

Seminar | January 22 | 2-4 p.m. | 736 Evans Hall

Jorge Garza Vargas, UC Berkeley

With the introduction of free independence by D.V. Voiculescu, it became clear that in the framework of non-commutative probability there are other notions of independence different than that of (classical) independence. In 1997, R. Speicher defined a notion of universal product for which he showed that there are three types of independence. In the category of unital algebras the tensor and free... More >

### Differential Geometry Seminar: A polyhedron comparison theorem for 3-manifolds with positive scalar curvature

Seminar | January 22 | 2:10-3 p.m. | 939 Evans Hall

Chao Li, Stanford

We establish a comparison theorem for polyhedra in 3-manifolds with nonnegative scalar curvature, answering affirmatively a dihedral rigidity conjecture by Gromov. For a large collection of polyhedra with interior non-negative scalar curvature and mean convex faces, we prove that the dihedral angles along its edges cannot be everywhere less or equal than those of the corresponding Euclidean...

### Shuttle Catalysis – a Conceptual Blueprint for Reversible Functional Group Transfer

Seminar | January 22 | 3-4 p.m. | 775 Tan Hall

Prof. Bill Morandi, Max-Planck-Institut für Kohlenforschung

Catalytic reversible reactions, such as alkene metathesis and transfer hydrogenation, have had an auspicious impact on the molecular sciences. This presentation will describe our efforts to develop related “shuttle catalysis” reactions for the functionalization and defunctionalization of organic compounds.1-5 These reactions avoid the use of toxic reagents (e.g. HCN, CO) through the reversible...

### Arithmetic Geometry and Number Theory RTG Seminar: The Brauer group of some algebraic stacks

Seminar | January 22 | 3:10-5 p.m. | 748 Evans Hall | Note change in date

Minseon Shin, UC Berkeley

We will discuss recent developments in the computation of Brauer groups of some algebraic stacks, namely the moduli stack of elliptic curves $\mathscr M_{1,1}$ and torsion $\mathbb G_m$-gerbes.

Seminar Format: The seminar consists of two 50-minute talks, a pre-talk (3:10-4:00) and an advanced talk (4:10-5:00), with a 10-minute break (4:00-4:10) between them. The advanced talk is a regular formal... More >

### Understanding rare events in models of statistical mechanics

Seminar | January 22 | 4-5 p.m. | 1011 Evans Hall

Shirshendu Ganguly, UC Berkeley

Statistical mechanics models are ubiquitous at the interface of probability theory, information

theory, and inference problems in high dimensions. In this talk, we will focus on

sparse networks, and polymer models on lattices. The study of rare behavior (large deviations)

is intimately related to the understanding of such models. In particular, we will

consider the rare events that a sparse... More >

### Panel Discussion Honoring San Francisco Mayor Ed Lee

Panel Discussion | January 22 | 4-5:30 p.m. | Boalt Hall, School of Law, Room 105

Erin Dineen, Berkeley Law

The Bay Area and the Berkeley Law community lost one of its shining lights when Mayor Ed Lee passed away. Mayor Lee was a graduate of Berkeley Law (Class of 1978). His career was dedicated to public service and he made an enormous difference in so many people’s lives and in the Bay Area.

On Monday January 22nd, we will be holding a panel discussion about Ed Lee’s contributions and legacy. We... More >

### Thematic Seminar: Numerical Methods: Machine Learning at Facebook

Seminar | January 22 | 4:10-5 p.m. | 939 Evans Hall

Mark Tygert, Facebook

Machine intelligence for processing big data sets is big business. A mathematician's point of view has led to (1) effective large-scale principal component analysis and singular value decomposition, and (2) theoretical foundations for convolutional networks (convolutional networks underpin the recent revolution in artificial intelligence).
