Rigmor Baraas, OD, PhD, National Centre for Optics, Vision and Eye Care, Department of Optometry, Radiography and Lighting Design, University of South-Eastern Norway, Kongsberg, Norway

Optical coherence tomography (OCT) and adaptive optics scanning light ophthalmoscopy (AOSLO) have become invaluable tools for mapping the ultrastructure of the retina in living humans. OCT imaging has revealed considerable variation in retinal layer thickness, foveal shape and morphology. AOSLO imaging has revealed large variation in cone mosaics, both peak and eccentricity dependence density...   More >

### Combinatorics Seminar: LLT Polynomials, k-Schur Functions, and Positivity

Seminar | May 6 | 12:10-1 p.m. | 939 Evans Hall

Christopher Miller, UC Berkeley

Department of Mathematics

Both LLT polynomials and k-Schur functions were derived from the study of Macdonald polynomials, and have proved to be fruitful areas of study. A conjecture due to Haglund and Haiman states that k-bandwidth LLT polynomials expand positively into k-Schur functions. This is trivial in the case k=1 and has been recently proved for k=2. In this talk, I will present a proof for the case k=3. To this...   More >

### String-Math Seminar: Searching for Lie groups of the XXI century

Seminar | May 6 | 2-3 p.m. | 402 LeConte Hall

Andrei Okounkov, Columbia University

Department of Mathematics

It has been understood for some time now that many highlights of Lie theory, such as the representation-theoretic theory of special functions, or the Kazhdan–Lusztig theory, have a natural extension to a much broader setting, the boundaries of which are yet to be explored. In this extension, the focus is shifting from a group $$G$$ to various classes of algebraic varieties that possess the key...   More >

### Northern California Symplectic Geometry Seminar: Divisor complements in Calabi-Yau symplectic manifolds

Seminar | May 6 | 2:30-3:30 p.m. | 384H STANFORD

Umut Varolgunes, Stanford

Department of Mathematics

Let $(M,\omega )$ be a closed symplectic manifold. Consider a closed symplectic submanifold $D$ whose homology class is a positive multiple of the Poincare dual of $[\omega ]$. The complement of $D$ can be given the structure of a Liouville manifold, with skeleton $S$. We prove that $S$ cannot be displaced from itself inside $M$ by a Hamiltonian isotopy if we assume that $c_1(M)=0$. Under the...   More >

### Between Shannon and Hamming: how bad can the channel be?: BLISS Seminar

Seminar | May 6 | 3-4 p.m. | 540 Cory Hall

Anand Sarwate, Rutgers

The information theory community has traditionally studied two different models for communication. The Shannon-theoretic model treats the channel’s impact as random, so codes must correct almost all error patterns of a given weight; this is an average-case analysis. The coding-theoretic (Hamming-theoretic?) model treats the channel as adversarial, so codes must correct all error patterns of a...   More >

### Differential Geometry Seminar: Moduli spaces of spherical surfaces with conical singularities

Seminar | May 6 | 3:10-4 p.m. | 939 Evans Hall

Dmitri Panov, University College London

Department of Mathematics

A spherical surface with $n$ conical singularities is a surface $S$ with cone points $x_1, \dots ,x_n$ and a metric $g$, such that $g$ has curvature 1 on the complement $S \setminus (x_1,...,x_n)$ and has a conical singularity of angle $2\pi (\theta _i)$ at each $x_i$. Moduli spaces of spherical metrics with fixed angles are intriguing objects. Up to very recently the most basic questions about...   More >

### Topology Seminar (Introductory Talk): Scissor Congruence and Mixed Tate Motives

Seminar | May 8 | 2:10-3 p.m. | 740 Evans Hall

Daniil Rudenko, University of Chicago

Department of Mathematics

Scissor congruence theory of polytopes is an old subject going back to 19th century. One of its first major achievements was appearance of so-called Dehn invariant. This mysterious invariant could be properly understood and generalized in the context of the theory of mixed Hodge structures of mixed Tate type. I will explain this relation and show some applications to hyperbolic geometry.

Seminar | May 8 | 4:10-5 p.m. | 3 Evans Hall

Daniil Rudenko, University of Chicago

Department of Mathematics

I will explain how to construct a rational elliptic surface out of every non-Euclidean tetrahedra. This surface "remembers" the trigonometry of the tetrahedron: the length of edges, dihedral angles and the volume can be naturally computed in terms of the surface. The main property of this construction is self-duality: the surfaces obtained from the tetrahedron and its dual coincide. This leads to...   More >

Using our platform, we have demonstrated chalcogenide resonators with record high (for on-chip chalcogenide devices) Q-factor (1.2 x 10^7) and Brillouin lasers with record low (for on-chip chalcogenide devices) threshold power (2.5mW).

### Dissertation Talk: Expert-Level Detection of Acute Intracranial Hemorrhage on Head Computed Tomography using Deep Learning

Presentation | May 10 | 1-2 p.m. |  Sutardja Dai Hall

WEICHENG KUO

Head CT is the workhorse medical imaging modality used worldwide to diagnose neurologic emergencies. We demonstrated state-of-the-art exam-level classification performance, comparable to that of U.S. board-certified radiologists, in addition to robust localization of abnormalities, both of which are important to this application.

### Dissertation Talk: Solving Hard Computational Problems using Oscillator Networks

Seminar | May 10 | 3-4 p.m. | Cory Hall, 540A/B

Tianshi Wang, UC Berkeley

Over the last few years, there has been considerable interest in Ising machines, ie, analog hardware for solving difficult (NP hard/complete) computational problems effectively. We present a new way to make Ising machines using networks of coupled self-sustaining nonlinear oscillators. Our scheme is theoretically rooted in a novel result that connects the phase dynamics of coupled oscillator...   More >

### Solving Hard Computational Problems using Oscillator Networks: PhD Dissertation Talk

Seminar | May 10 | 3-4 p.m. | 540 Cory Hall

Tianshi Wang, Graduate Student, EECS Department, UC Berkeley

I will show that the phase dynamics of sub-harmonically injection locked coupled oscillator systems are governed by a Lyapunov function that continuizes the Ising Hamiltonian.
This result is used to devise a new Ising machine scheme that can use oscillators from many different physical domains.
A demonstration of a prototype CMOS oscillator-based Ising machine of 240 spins will follow the talk.

### Changing Production and Distribution Systems for Mass-Market Cultural Materials and Implications for Stewardship: The Case of Video Materials

Seminar | May 10 | 3:10-5 p.m. | 107 South Hall

Clifford Lynch

Information, School of

The way in which video (including âfilmâ) materials are produced and the pathways by which they are distributed have changed radically from the days of VHS or even DVD. This has broad implications for our cultural memory institutions and also for efforts to attempt to even understand patterns of availability of material for libraries, or the stewardship status of materials. Iâll present what I...   More >

### Dissertation Talk: Efficient Sampling of SAT and SMT Solutions for Testing and Verification

Seminar | May 10 | 3:30-4:30 p.m. | 373 Soda Hall

Rafael Dutra

The problem of generating a large number of diverse solutions to a logical constraint has important applications in testing, verification, and synthesis for both software and hardware. The solutions generated could be used as inputs that exercise some target functionality in a program or as random stimuli to a hardware module. The sampling of solutions can be combined with techniques such as fuzz...   More >

### Student Hosted Colloquium in Inorganic Chemistry: Using N,O to get to Yes. Catalytic Amination of Alkenes for Small Molecule and Polymer Synthesis

Seminar | May 10 | 4-5 p.m. | 120 Latimer Hall

College of Chemistry

N,O-Chelated ureate complexes of early transition metals can be used to catalytically add amines and N-heterocycles to both terminal and internal alkenes by hydroaminoalkylation. This alkene hydrofunctionalization reaction results in the generation of Csp3-Csp3 bonds in an atom-economic fashion and offers alternative disconnection strategies for the assembly of - and β-substituted...   More >
