Dysflective Cones: Differences in Cone Reflectivity and Function in Healthy Subjects
Confocal Adaptive Optics Scanning Laser Ophthalmoscope (AOSLO) images acquired in healthy subjects reveal small areas with diminished cone reflectivity. In a survey of AOSLO images these transient hyporeflective areas of cones were found in 19 of the 80 eyes. 3 healthy subjects with...   More >

Combinatorics Seminar: Near-Equality of Ribbon Schur Functions

Seminar | September 24 | 12-1 p.m. | 939 Evans Hall

 Foster Tom, UC Berkeley

 Department of Mathematics

We consider the problem of when the difference of two ribbon Schur functions is a single Schur function. We prove that this near-equality phenomenon occurs in fourteen infinite families and we conjecture that these are the only possible cases. Towards this converse, we prove that under certain additional assumptions the only instances of near-equality are among our fourteen families. In...   More >

String-Math Seminar: Exotic T-structure constructions using Quantum Affine Algebras

Seminar | September 24 | 2-3 p.m. | 402 LeConte Hall

 Sabin Cautis, University of British Columbia

 Department of Mathematics

We explain how quantum affine algebras can be used to systematically construct "exotic" t-structures. One of the application is to obtain exotic t-structures on certain convolution varieties defined using affine Grassmannians (these varieties play an important role in the geometric Langlands program, knot homology constructions, the coherent Satake category etc.) As a special case we also recover...   More >

Arithmetic Geometry and Number Theory RTG Seminar: Low degree points on families of curves

Seminar | September 24 | 3:10-5 p.m. | 784 Evans Hall

 Isabel Vogt, MIT

 Department of Mathematics

It is a classical theorem of Max Noether that the (geometric) gonality of a smooth plane curve of degree $d$ is $d-1$, and all minimal degree maps come from projection from a point on the curve. Debarre and Klassen proved an arithmetic strengthening of this result when the curve is defined over a number field: if $d \geq 8$, there are only finitely many algebraic points with residue degree...   More >

Keith Johnson, "Four phonetic discoveries: How I spent my sabbatical 'vacation'"

Colloquium | September 24 | 3:10-5 p.m. | 370 Dwinelle Hall

 Keith Johnson, UC Berkeley

 Department of Linguistics

In a scientifically young field like phonetics it is possible to make some relatively basic discoveries. I’ll talk about four that I made last year while on sabbatical.

1) Perceptual voice stereotypes are based on selective memory of spoken exemplars. This acoustic and perceptual study (with Eric Tracy of UNC-Pembroke) of gay men’s speech shows that listeners’ judgement of what sounds ‘gay’ is...   More >

Differential Geometry Seminar: Nilpotent structures and collapsing Ricci-flat metrics on K3 surfaces

Seminar | September 24 | 3:10-4 p.m. | 939 Evans Hall

 Jeff Viaclovsky, UC Irvine

 Department of Mathematics

I will discuss a new construction of families of Ricci-flat Kähler metrics on K3 surfaces which collapse to an interval, with Tian-Yau and Taub-NUT metrics occurring as bubbles. There is a corresponding singular fibration from the K3 surface to the interval, with regular fibers diffeomorphic to either 3-tori or Heisenberg nilmanifolds. This is joint work with Hans-Joachim Hein, Song Sun, and...   More >

The neural circuits underlying motor planning and short-term memory

Seminar | September 24 | 4-5 p.m. | 125 Li Ka Shing Center

 Karel Svoboda, Janelia Research Campus, HHMI

 Neuroscience Institute, Helen Wills

Our goal is to uncover the principles by which mammalian neural circuits perform fundamental computations, from perception to action. Cortex is parcellated into areas with distinct functions, each of which contains complex local circuits. Cortical areas in turn associate into mesoscale circuits with other cortical and subcortical areas via long-range connections. Information is represented by...   More >
