Quantifying the environmental influences on human health through the lens of human-microbial interactions: Dr. Wenyu Zhou, Stanford University
Seminar | February 24 | 10-11:30 a.m. | 1205 Berkeley Way West
Abstract: Our public health is threatened by widespread complex diseases such as diabetes and cardiovascular diseases, the etiology of which cannot be fully dissected from a single perspective. The commensal microbiome, recently emerged as a "hidden organ", should not be left behind owing to its pivotal role in modulating human health... More >

Wayfinding is a major challenge for visually impaired travelers, who often lack access to visual cues such as landmarks and informational signs that many travelers rely on for navigation. Indoor wayfinding is particularly challenging since the most commonly used source of location information for wayfinding, GPS, is inaccurate indoors. We describe a computer vision approach to indoor localization... More >

Abstract: Granular materials are common in everyday life but are historically difficult to model. This has direct real-world ramifications owing to the prominent role granular media play in multiple industries and in terrain dynamics. One can attempt to track every grain with discrete element methods (DEM), but realistic systems are often too large for this approach and a continuum model is... More >

Seismic assessment and strengthening of historic buildings present
challenges that are not present on more routine design projects. Historic projects require a re-prioritization of engineering
considerations to be successful. Sherith Israel and Hibernia Bank, two pre-1906 buildings in San Francisco epitomize that reprioritization; both projects left the historic interiors and exteriors... More >

Since the 1980s, Chief Executive Officers (CEO) pay has exploded, largely in the form of equity-based incentive compensation such as stock awards and options. Using a two-tiered principal-agent model, we show that aligning managers incentives with shareholder interests through equity-based pay can lower workers wages. Analyzing a sample that matches firm, manager, and worker... More >

are represented and interpreted on a global stage

Nonsymmetric Macdonald polynomials were introduced independently by Opdam and Macdonald and then generalized by Cherednik. These polynomials not only generalize the two-parameter symmetric Macdonald polynomials, when specialized to $t=0$ they were shown by Sanderson and Ion to arise as characters of affine Demazure modules. In this talk, I will present a new crystal-theoretic proof of this fact... More >

We will discuss the definition of Coulomb branches in N=4 SUSY field theories in 3 dimensions, adapting the Braverman-Finkelberg-Nakajima construction to the case of non-polarized representation. Their computation can be done by an Abelianization theorem. Time permitting, I will discuss the associated TQFT.

ERG Colloquium: Robert Connell: Maroon Ecology: Survival, Sovereignty, and Solar Power in the Afterlife of Slavery
Colloquium | February 24 | 3-4:30 p.m. | 101 Barker Hall
Robert Connell, University of California, Davis
This talk presents a socio-historical anthropology of power in the high-stakes environmental justice struggle of a Black Caribbean autonomous society. Jamaican Maroon contemporary political transformations and sovereignty aspirations stand in opposition to bauxite mining that threatens their highland forest traditional territory. Although Maroon political systems were founded in the context of... More >

Arithmetic Geometry and Number Theory RTG Seminar: Torsion points on the Catalan curve $y^n = x^d + 1$
Seminar | February 24 | 3:10-5 p.m. | 740 Evans Hall
Vishal Arul, MIT
The goal of this talk is to classify torsion points on the curve $y^n = x^d + 1$ over the complex numbers, where $n$, $d$ are at least 2 and are coprime. This generalizes a result of Grant and Shaulis, who provide this classification for $n = 2$ and $d \ge 7$ prime. We will motivate the method by studying a theorem of Poonen and Stoll that the only torsion points on a generic hyperelliptic curve... More >

A 4-manifold is constructed with some curious metric properties; or maybe it is many 4-manifolds masquerading as one, which would explain why it looks curious. Anyway, knots in the 3-sphere with complete finite volume hyperbolic metrics on their complements play a role in this story.

Abstract: Operating disruptions result in enormous costs across spatial-temporal networks. For instance, air traffic disruptions result in flight delays, cancellations, passenger misconnections, creating high costs to aviation stakeholders. Businesses often design recovery plans in response to past disruptions while preparing for future disruptions. However, future disruptions often can only be... More >

This talk is centered around trend filtering, a relatively recent method for nonparametric regresson based on penalizing the L1 norm of discrete derivatives. We will discuss some of the unique features of this method that "make it work", and briefly cover extensions to additive models and graphs. We will finish by discussing connections to what are an old topic in numerical analysis---discrete... More >

Interactive proof systems are a classic idea in theoretical computer science, and have led to fundamental advances in complexity theory (hardness of approximation and the PCP theorem) and cryptography. Remarkably, in quantum information, interactive proof systems with multiple provers have become an important tool for studying quantum entanglement, extending the pioneering work of Bell... More >

In an effort to improve both environmental and agronomic outcomes, while building resilience in the face of climate change, there is growing interest in soil carbon sequestration and, overall, soil health. While there is a general consensus as to the overarching principles that promote soil carbon storage and soil health, the impact of any given practice across the range of climates, soil types,...

Analysis and PDE Seminar: Almost global well-posedness for quasilinear strongly coupled wave-Klein-Gordon systems in two space dimensions
Seminar | February 24 | 4:10-5 p.m. | 939 Evans Hall
Mihaela Ifrim, UW Madison
We prove almost global well-posedness for quasilinear strongly coupled wave-Klein-Gordon systems with small and localized data in two space dimensions. We assume only mild decay on the data at infinity as well as minimal regularity. We systematically investigate all the possible quadratic null form type quasilinear strong coupling nonlinearities, and provide a new, robust approach for the proof.
ATC Lecture Margaret Rhee, "In Search for My Robot": Emergent Media, Racialized Gender, and Creativity
Colloquium | February 24 | 6:30-8 p.m. | Berkeley Art Museum and Pacific Film Archive, Osher Theater
Margaret Rhee, Assistant Professor, SUNY Buffalo; Visiting Scholar, NYU
Robots, like any technology, are not "objective" or "universal"; Instead, machines reveal the process of social formation. This talk demonstrates how difference--such as race, gender, and sexuality--are shaped by and co-constitutive with technological developments. Specifically, this talk illustrates how the robot is a primary locus of racialization for Asian Americans within modernitys... More >
