Civil and Environmental Engineering Department Seminar: Uncertainties, Risk, and Learning in Future Infrastructure Systems

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

 Marco Broccardo

 Civil and Environmental Engineering (CEE)

Engineers increasingly rely on computational models to predict adverse events that influence engineering systems and to make critical decisions that impact the safety and well-being of our society. Examples include but are not limited to the safety of structure and infrastructure systems subjected to natural and man-made hazards and the performance and resilience of such systems. Given such high...   More >

A bottleneck for visual word recognition in brain and behavior

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

 Dr. Alex White, PhD, University of Washington

 Neuroscience Institute, Helen Wills

In most environments, the visual system is confronted with many relevant objects simultaneously. That is especially true during reading. How many words on this page can you recognize at once? I will present behavioral evidence that a fundamental processing bottleneck prevents recognition of more than one word at a time. I will then present a neuroimaging study designed to identify the source of...   More >

Kinematics of Non-Spherical Particles Suspended in Turbulence at Inertial and Dissipation Scales: Fluids Seminar

Seminar | March 11 | 12-1 p.m. | 3110 Etcheverry Hall

 Professor Evan Variano, Department of Civil and Environmental Engineering, University of California, Berkeley

 Department of Mechanical Engineering (ME)

Natural particles suspended in water are often non-spherical. We explore the ways in which particle size and shape affect particle motion in homogeneous isotropic turbulent flow. Laboratory measurements and numerical simulations are used to explore the kinematics of particles. Particle shapes are idealized and motivated by open questions in environmental engineering, notably regarding plankton,...   More >

 Shaun O'Grady, Department of Psychology

 Department of Psychology

What is the mental representation of probability and how does it develop? What role do education and experience play in understanding probability? In this talk I will present the results of several experiments investigating probability judgments in children and adults. In the first part of the discussion I will present data from 3 Experiments in which adult participants perform a ratio comparison...   More >

Combinatorics Seminar: Mobius Inversion as Duality for Hopf Monoids

Seminar | March 11 | 12:10-1 p.m. | 939 Evans Hall

 Mario Sanchez, UC Berkeley

 Department of Mathematics

In this talk I will introduce an interesting connection between the theory of Hopf monoids in combinatorics and Mobius inversion. Roughly, a Hopf monoid is an algebraic abstraction of families of combinatorial objects which have an operation which combines objects and an operation which breaks objects apart. Like many algebraic structures, Hopf monoids have a nice notion of duality. We will show...   More >

 Dr. Nicholas Chilton, University of Manchester

 College of Chemistry

Following our discovery of the first dysprosium metallocenium cation, [Dy(Cpttt)2][B(C6F5)4], which is the vanguard of the new generation of high-temperature single-molecule magnets, we have been investigating the magnetic relaxation dynamics of various dysprosium-based single-molecule magnets (SMMs) by experimental and theoretical techniques. Here we present our recent results in unravelling the...   More >

String-Math Seminar: HOMFLY-PT link homology from a stack of D2-branes.

Seminar | March 11 | 2-3 p.m. | 402 LeConte Hall

 Lev Rozansky, University of North Carolina (Chapel Hill)

 Department of Mathematics

This is a joint work with A. Oblomkov exploring the relation between the HOMFLY-PT link homology and coherent sheaves over the Hilbert scheme of points on \(\mathbb C^2\).

We consider a special object in the 2-category related to the Hilbert scheme of n points on \(\mathbb C^2\). We define a homomorphism from the braid group on n strands to the monoidal category of endomorphisms of this object....   More >

Information-theoretic Privacy: Leakage measures, robust privacy guarantees, and generative adversarial mechanism design: BLISS Seminar

Seminar | March 11 | 3-4 p.m. | 540 Cory Hall

 Lalitha Sankar, Arizona State Univ.

 Electrical Engineering and Computer Sciences (EECS)

Privacy is the problem of ensuring limited leakage of information about sensitive features while sharing information (utility) about non-private features to legitimate data users. Even as differential privacy has emerged as a strong desideratum for privacy, there is also an equally strong need for context-aware utility-guaranteeing approaches in most data sharing settings. This talk approaches...   More >

Aging, Memory and Alzheimer’s disease

Colloquium | March 11 | 3:30-5 p.m. | 1104 Berkeley Way West

 William Jagust, Psychology

 Department of Psychology

It has long been known that older individuals often experience decline in their episodic memory abilities. Within the past decade, new approaches have revealed the frequent presence of the aggregated proteins beta-amyloid and tau in the brains of cognitively normal older people. These proteins are also associated with Alzheimer’s disease. By imaging these proteins in normal older people, and...   More >

Alper Atamturk – Sparse Estimation: Closing the Gap Between L0 and L1 Models

Seminar | March 11 | 3:30-4:30 p.m. | 1174 Etcheverry Hall

 Alper Atamturk, University of California, Berkeley

 Industrial Engineering & Operations Research

Sparse statistical estimators are increasingly prevalent due to their ease of interpretability and superior out-of-sample performance. However, sparse estimation problems with an L0 constraint, restricting the support of the estimators, are challenging (typically NP-hard, but not always) non-convex optimization problems. Consequently, academicians and practitioners commonly turn to convex L1...   More >
