We first briefly introduce the theory of e-values and e-processes, and then briefly discuss their applications in four areas: a) Combining dependent p-values; b) Selective inference procedures; c) Backtesting risk measures; d) Online large language models (LLM) watermark detection. \r\n\r\n*Lecture 2, November 19, 4 pm East Hall 1360: Risk aversion, insurance propensity, and choice under dependence*\r\nWe provide a foundation of risk aversion by showing that this attitude is fully captured by the propensity to seize insurance opportunities. Our foundation well accords with the commonly held prudential interpretation of risk aversion that dates back to the seminal works of Arrow (1963) and Pratt (1964). These analyses are special cases of results in the general framework of choice under dependence.\r\n\r\n*Lecture 3, November 20, 4 pm East Hall 4448: Bridging pure risk and ambiguity in risk measures and optimization*\r\nWe discuss optimization and modeling of ambiguity in risk management and decision making. We first discuss two different approaches in optimization under uncertainty, the worst-case risk approach and the model aggregation approach. Then we present a mathematical framework using a sigma-algebra to distinguish between pure risks and ambiguity.\r\n\r\nDr. Ruodu Wang is Tier-1 Canada Research Chair in Quantitative Risk Management and Professor of Actuarial Science and Quantitative Finance at the University of Waterloo.

A new type of clock based on the internal transitions of atomic nuclei, dubbed nuclear clocks, was proposed by Peik and Tamm in 2003. Among nuclei, the thorium-229 nucleus is unique in having a transition at low enough energy to be accessible with present-day laser technology, and laser spectroscopy of the 148 nm thorium-229 nuclear isomer transition was first demonstrated by three groups nearly simultaneously in 2024. Due to the higher energy scales and additional fundamental interactions present in the nucleus, nuclear transitions are much more sensitive to small deviations from the predictions of the Standard Model than atomic transitions. Thus, thorium nuclear clocks may offer insights about unification theories, the nature of dark matter, or other physics beyond the Standard Model.\r\n\r\nI will begin this talk with a brief overview of the thorium-229 nuclear isomer transition and the two experimental approaches currently being pursued to build thorium nuclear clocks: one based on thorium doped into solid-state hosts and the other based on trapped and laser-cooled thorium ions. Next, I will present the design and current status of a trapped-ion thorium clock experiment under construction in my lab at UCLA. Finally, I will conclude with a discussion of the fundamental physics reach of this and other thorium nuclear clocks.\r\n\r\nBio: David Leibrandt is a Professor in the Department of Physics & Astronomy at UCLA.
