### Civil and Environmental Engineering Department Seminar: Granular Mechanics: Soil, Additive Manufacturing, and Beyond

Seminar | March 18 | 10-11 a.m. | 542 Davis Hall

Michelle Bernhardt-Barry

The advent of additive manufacturing (AM) has opened many new fields of study related to multi-scale granular material behavior and it has the potential to transform the way in which we design and construct geotechnical infrastructure. This talk will highlight several areas of ongoing research within Dr. Bernhardt-Barry’s group and opportunities for expanding this research in the future. The...   More >

Seminar | March 18 | 11:10 a.m.-12:30 p.m. | 489 Minor Hall

Dr. MiYoung Kwon, Department of Ophthalmology and Visual Sciences, University of Alabama at Birmingham

As our population ages, a growing number of people must adapt to normal and pathological aging processes. Thus, understanding how the adult human brain deals with degraded sensory input is increasingly important. In this talk, I will present behavioral and brain-imaging evidence suggesting that visual deprivation results in compensatory changes in the adult human visual system. Here I will...   More >

### STROBE Seminar: 3D Phase Contrast Tomography with Atomic Resolution

Seminar | March 18 | 12-1 p.m. | 775A Tan Hall

David Ren, Waller Group, UC Berkeley

College of Chemistry

Electron tomography is a technique used in both materials science and structural biology to image features well below optical resolution limit. In this work, we present a new algorithm for reconstructing the three-dimensional(3D) electrostatic potential of a sample at atomic resolution from phase contrast imaging using high-resolution transmission electron microscopy. Our method accounts for...   More >

### Leveraging Science to Improve the Lives of Children and Adolescents: IHD/Developmental Colloquium featuring a cross-disciplinary discussion

Colloquium | March 18 | 12-1 p.m. | 1102 Berkeley Way West

Institute of Human Development

There has been a great deal of progress in the scientific understanding of how children learn and develop—and the social contexts, conditions, and systems that can promote health, well-being, learning, and social success. There are many challenges to leveraging this science for real-world impact. Yet, there are also exciting opportunities—and compelling reasons for overcoming these
challenges.

### Combinatorics Seminar: Cone valuations, Gram's relation, and combinatorics

Seminar | March 18 | 12:10-1 p.m. | 939 Evans Hall

Raman Sanyal, Goethe Universitat-Frankfurt and Simons Institute

Department of Mathematics

The Euler-Poincare formula is a cornerstone of the combinatorial theory of polytopes. It states that the number of faces of various dimensions of a convex polytope satisfy a linear relation and it is the only linear relation (up to scaling). Gram’s relation generalizes the fact that the sum of (interior) angles at the vertices of a convex $n$-gon is $(n-2)\pi$. In dimensions $3$ and up, it is...   More >

### Political Economy Seminar: “Diversity in Schools: Immigrants and the Educational Performance of Natives”

### String-Math Seminar: A Sheaf-Theoretic model for $$SL(2,\mathbb C)$$ Floer homology

Seminar | March 18 | 2-3 p.m. | 402 LeConte Hall

Mohammed Abouzaid, Columbia University

Department of Mathematics

I will describe joint work with Ciprian Manolescu on constructing an analogue of instanton Floer homology replacing the group $$SU(2)$$ by $$SL(2,\mathbb C)$$. Having failed to do so using the standard Floer theoretic tools of gauge theory and symplectic topology, we turned to sheaf theory to produce an invariant. After describing our approach, I will discuss some features of this theory that are...   More >

Andrzej Sitarz, Jagiellonian University, Krakow

Department of Mathematics

Starting from the description of the Standard Model of particle physics based on noncommutative geometry we study the properties of the matrix algebras in the model. We demonstrate that there exists a new previously unknown geometric feature of the model, which can be mathematically stated that the Hilbert space of particles is a self-Morita equivalence bimodule for the associated generalization...   More >

### Arithmetic Geometry and Number Theory RTG Seminar: Bounding 5-torsion in class groups using Elliptic Curves

Seminar | March 18 | 3-5 p.m. | 748 Evans Hall

Jacob Tsimerman, University of Toronto

Department of Mathematics

We discuss a new method to bound 5-torsion in class groups using elliptic curves. The most natural “trivial” bound on the n-torsion is to bound it by the size of the entire class group, for which one has a global class number formula. We explain how to make sense of the n-torsion of a class group intrinsically as a “dimension 0 selmer group”, and by embedding it into an appropriate...   More >

### Evidence for the Suffixing Preference

Colloquium | March 18 | 3:10-5 p.m. | 370 Dwinelle Hall

Matthew S. Dryer, Professor of Linguistics, University at Buffalo

Department of Linguistics

It might be thought that there already exists overwhelming evidence for a preference for suffixes over prefixes. However, strictly speaking, most of the available evidence is evidence for an orthographic suffixing preference, i.e. a preference for suffixes over prefixes in the orthographic representations of words in grammatical descriptions. Haspelmath (2011), however, questions how reliable...   More >

### Differential Geometry Seminar: On the large time collapsing of Ricci flows

Seminar | March 18 | 3:10-4 p.m. | 939 Evans Hall

Department of Mathematics

In contrast to finite time singularities of Ricci flows, it is known that collapsing with bounded sectional curvature may occur as we approach time infinity along immortal Ricci flows. In this talk I will show that along an immortal Ricci flow with uniformly bounded diameter and sectional curvature, an unbounded sequence of time slices sub converges to a Ricci flat orbifold.

### Jeffrey Linderoth – Perspectives on Integer Programming in Sparse Optimization

Seminar | March 18 | 3:30-4:30 p.m. | 1174 Etcheverry Hall

Jeffrey Linderoth, University of Wisconsin - Madison

Abstract: Algorithms to solve mixed integer linear programs have made incredible progress in the past 20 years. Key to these advances has been a mathematical analysis of the structure of the set of feasible solutions. We argue that a similar analysis is required in the case of mixed integer quadratic programs, like those that arise in sparse optimization in machine learning. One such analysis...   More >

### Quantitative analysis of energy metabolism: Dr. Sheng Hui, Lewis-Sigler Institute for Integrative Genomics, Princeton University

Seminar | March 18 | 4-5 p.m. | 101 Morgan Hall

Abstract:
Mammals generate energy by burning dietary carbon into CO2. The largest calorie source for most mammals is carbohydrate, which is broken down into glucose in the small intestinal lumen. Glucose is then absorbed and circulates in the blood stream. To acquire energy, tissues are generally assumed to take in glucose and break it down to CO2 through the concerted action of glycolysis and...   More >
