Adult Mortality Determinants in Low and Middle Income Countries and Comparisons with High Income Countries: A Comparative Workshop on Adult Mortality Determinants
Conference/Symposium | February 27 | 9 a.m.-5 p.m. | Barrows Hall, Social Science Matrix Conference Room, 8th floor

Civil and Environmental Engineering Department Seminar: Wind Effects on Flexible Structures: A New Perspective
Seminar | February 27 | 10-11 a.m. | 542 Davis Hall
Wind effects on flexible structures such as high-rise buildings and long-span bridges, governed by the Navier-Stokes equations, are not adequately represented by a conventional linear analysis framework.

We consider the problem of placing $k$ queens on an $n \times n$ chessboard so that the number of unattacked squared is as large as possible. We focus on the domain where $k$ is small relative to $n$. We are able to solve this problem by relating it to various related problems in additive combinatorics.

If $M$ is a compact manifold, a generic smooth function $f:M\to R$ can tell us about the topology of $M$. Classically, one obtains a CW decomposition of $M$ (up to homotopy equivalence) and can then use cellular homology. I will focus on a newer approach which involves constructing a chain complex by counting the flow lines of the gradient of $f$. The resulting homology turns out to be... More >

In the early 90's, Bartnik defined a localization (to finite regions) of the mass of complete asymptotically flat metrics on 3-manifolds with nonnegative scalar curvature. The Bartnik mass has a number of favorable properties. A deeper understanding of the mass requires the resolution of several conjectures posed by Bartnik, leading to interesting global problems in geometric PDE. We will discuss... More >

I will discuss some mathematical aspects of instanton counting in two different physical theories- one with gauge group of rank N, the other of small fixed rank. It will be shown that instanton sectors of both theories are equivalent in the N to infinity limit.

We begin by talking about probability measure preserving actions of discrete groups, and introduce the notion of the Group Measure Space construction, or the cross product von Neumann algebra. We will then discuss about free and ergodic actions and the measurable functions fixed by these. We will conclude by presenting and proving the key theorem of this talk: The free action on an $L^\infty $... More >

In this talk we will present a fundamental role that directed information and causal conditioning has in communication with feedback, gambling with causal side information, causal MMSE estimation, statistical physics, and causal inference between two processes.
We will begin by defining and establishing some key properties of the notions of causal conditioning and directed information. These... More >

ALFABURST is an FRB search pipeline for Arecibo then runs commensally during ALFA observations. It is run in conjunction with the current SERENDIP system as SETIBURST. ALFABURST has been in operation since August 2015, and in that time has observed for 45 days total, the majority of which is outside the galactic plane. I will report on the current status of the system, analysis of the initial... More >

The synapse between hair cells and auditory nerve fibers provides precise temporal information about acoustic events, such as transients in complex stimuli and the phase of sound waveforms at frequencies up to the kHz range. To accomplish these tasks, the synapse produces a high rate of spontaneous and stimulus-driven discharge in auditory-nerve fibers, with irregular spike trains and little or... More >
Student Algebraic Geometry Seminar: The Geometry of Macdonald Polynomials (or The Combinatorics of Hilbert Schemes)
Seminar | February 27 | 4-5 p.m. | 891 Evans Hall
Jeremy Meza, UC Berkeley
In 1988, Macdonald introduced his eponymous \(q,t\)-symmetric functions, which he conjectured were polynomials with non-negative integer coefficients. It was not until 2001 when Haiman proved this purely combinatorial conjecture using the underlying geometry subtly lurking in the background. In this talk I will outline Haiman's proof. Along the way, I will review symmetric function theory,... More >

One challenge of understanding how the brain works is the complexity of neural circuits. These circuits are composed of hundreds of thousands of neurons that are interconnected in a highly distributed fashion. Optical methods provide a route to record and manipulate the neural activity of a small subset of these cells with cellular resolution. The desire to access a larger volume with higher... More >

One challenge of understanding how the brain works is the complexity of neural circuits. Optical methods provide a route to record and manipulate the neural activity of a small subset of neuron cells with cellular resolution. In this talk, I will discuss our approach to tackling the above challenges through novel three-dimensional (3D) imaging and optical manipulation methods.
