Neuroscience Institute, Helen Wills

Michael Telias's Abstract

Retinoic acid is the trigger for neural hyperactivity in retinal degeneration and

blocking its receptor unmasks light responses and augments vision

Light responses are initiated in photoreceptors, processed by interneurons, and synaptically transmitted to retinal ganglion cells (RGCs), which send information to the brain. Retinitis pigmentosa (RP) is a blinding... More >

### Machine Learning Data-Driven Discretization Theories, Modeling and Applications: SEMM Seminar

Seminar | February 4 | 12-1 p.m. | 502 Davis Hall

Wing Kam Liu, PhD, PE, Northwestern University/Global Center on Advanced Material Systems and Simulation

Civil and Environmental Engineering (CEE)

An open problem in data-driven methods for mechanical science is the efficient and accurate description of heterogeneous material behavior that strongly depends on complex microstructure. To explore the future development and the adaptation of data-driven methods, new mathematical and computational paradigms and broad flexible frameworks are needed.

### UCB-UCSF Joint Medical Program Head of Foundational Medical Science Job Talk

Conference/Symposium | February 4 | 12-1 p.m. | 5101 Berkeley Way West

Lee HangFu, M.D., MBA

UCB-UCSF Joint Medical Program

It has been nearly half a century since the McMaster University introduced the Problem-Based Learning (PBL) pedagogy in medical education. Since then, hundreds of reviews and study reports have identified many critical issues affecting the success of the PBL unit. Nonetheless, we are still debating the efficacy and success of the PBL program. In his presentation, Dr. HangFu will be discussing the... More >

### Combinatorics Seminar: Varieties of signature tensors

Seminar | February 4 | 12:10-1 p.m. | 939 Evans Hall | Note change in date

Bernd Sturmfels, UC Berkeley and Max Planck Institute

We discuss recent developments in combinatorial algebraic geometry that were motivated by the study of rough paths in stochastic analysis. Every path in a real vector space is encoded in a signature tensor whose entries are iterated integrals. As the path varies over a nice family, we obtain an algebraic variety with interesting properties. Combinatorialists will especially enjoy the role played... More >

Seminar | February 4 | 2-3:30 p.m. | 639 Evans Hall

### Probabilistic Operator Algebra Seminar: Conditionally free random variables: the two-states framework

Seminar | February 4 | 2-4 p.m. | 736 Evans Hall

Jorge Garza Vargas, UC Berkeley

In non-commutative probability the notion of stochastic independence is not unique. Therefore an extension of free probability which produces a larger variety of limit laws is certainly of interest. In this seminar we will review the notion of conditional freeness, introduced by Bozejko and Speicher. We will survey some of the combinatorial and analytic tools that are used in this setting and...

### Seminar 231, Public Finance:

Seminar | February 4 | 2-4 p.m. | 597 Evans Hall

### String-Math Seminar: Magnificent Four with color

Seminar | February 4 | 2-3 p.m. | 402 LeConte Hall

Nicolo' Piazzalunga, Stony Brook & SCGP

I will present the rank \(N\) magnificent four theory, which is the supersymmetric localization of \(U(N)\) super-Yang-Mills theory with matter on a Calabi-Yau fourfold, and conjecture an explicit formula for the partition function \(Z\): it has a free-field representation, and surprisingly it depends on Coulomb and mass parameters in a simple way. Based on joint work with N.Nekrasov.

### Northern California Symplectic Geometry Seminar: Contact submanifolds in higher dimensions

Seminar | February 4 | 2:30-3:30 p.m. | 740 Evans Hall

Roger Casals, UC Davis

In this talk, I will discuss our understanding of contact submanifolds in higher dimensions. First, I will introduce the problems we are interested in and the current techniques we have to address them. In the main focus of the talk, I will present the construction of contactomorphic (and smoothly isotopic) contact submanifolds which are actually not contact isotopic. This resolves one of the...

### Differential Geometry Seminar: Cone spherical metrics

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

Bin Xu, University of Science and Technology of China

Cone spherical metrics are conformal metrics with constant curvature one with finitely many conical singularities on compact Riemann surfaces. The existence problem of such metrics has been open over twenty years. I will introduce the respectful audience some progress on this problem joint with Qing Chen, Xuemiao Chen, Yiran Cheng, Bo Li, Lingguang Li, Santai Qu, Jijian Song, Yingyi Wu and Xuwen... More >

### Canceled - to Be Postponed: Lifeworlds of Indigenous Languages

Colloquium | February 4 | 3:10-5 p.m. | 370 Dwinelle Hall

Beth Piatote, UC Berkeley

How do the underlying structures, epistemologies, and cultural practices associated with Indigenous languages in North America enrich the study of disciplines beyond linguistics? Drawing on my own work in Nez Perce language and literature, as well as examples from other scholars, I will present some of the current influences of Indigenous language “lifeworlds” shaping scholarship in law,...

### Statistical inference for infectious disease modeling

Seminar | February 4 | 4-5 p.m. | 1011 Evans Hall

Po-ling Loh, University of Wisconsin-Madison

We discuss two recent results concerning disease modeling on networks. The infection is assumed to spread via contagion (e.g., transmission over the edges of an underlying network). In the first scenario, we observe the infection status of individuals at a particular time instance and the goal is to identify a confidence set of nodes that contain the source of the infection with high probability....

### Northern California Symplectic Geometry Seminar: H-principle for complex contact structures on Stein manifolds

Seminar | February 4 | 4-5 p.m. | 740 Evans Hall

Franc Forstneric, University of Ljublana

The aim of this talk is to present a first attempt towards homotopy classification of holomorphic contact structures on Stein manifolds. We introduce the notion of a formal complex contact structure and show that any such structure on an odd dimensional Stein manifold $X$ is homotopic (through formal contact structures) to a genuine holomorphic contact structure on a Stein domain in X which is...

### The Paris Review: Women at Work with Emily Nemens

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

Berkeley Art Museum and Pacific Film Archive

What does it mean to be a woman at work in the creative arts in 2019? The Paris Review’s new editor, Emily Nemens, reflects on this question through the lens of the storied literary quarterly’s Writers at Work interview series, the work of contemporary contributors, and her own creative practice as a writer and illustrator.
