SUMMARY:Workshop / Seminar:Generative AI Tutorial Series: From Search to Synthesis: AI Tools for Literature Discovery and Summarization
DESCRIPTION:Join this session to learn more about generative AI tools that can assist you with literature discovery\, summarization\, and synthesis. Featured tools include Open AI’s chatGPT\, UMGPT\, Anthropic’s Claude\, ResearchRabbit\, and more. Bring your laptops for a hands-on tutorial at the end of the workshop.\n\nAbout the series: Generative AI is revolutionizing the landscape of research by enabling unprecedented levels of automation and innovation\, and facilitating major breakthroughs across all research fields. To leverage this\, MIDAS and the College of Literature\, Science\, and the Arts are co-hosting a series of tutorials on Generative AI during the Winter ’24 semester.\n\nIf you are a U-M researcher looking to learn more about when\, why\, and how to integrate Generative AI tools into your research\, join us for our upcoming sessions. We cover topics ranging from administrative tasks\, literature review and synthesis\, data analysis\, and writing and presentations. No prior experience with Generative AI tools is required. Participants will need to supply their own laptop for each session.\n\nLocation: all sessions will be held in-person. We are not able to offer live-streaming for this series. Recordings and materials will be posted to the event page after each session.

SUMMARY:Lecture / Discussion:Nick Ellis Dissertation Defense
DESCRIPTION:This dissertation focuses on analytical developments to triple oxygen isotope measurements (Δ′17O) and their potential for new applications in the paleosciences. In this dissertation\, I explore the utility of Δ′17O as a paleoecological tool using the fossil teeth of Early Eocene mammals. Furthermore\, I use these Δ′17O measurements to probe global biological productivity in the Early Eocene.\n\nChapter 2 introduces a new analytical method for making high-precision (< 10 ppm 1σ uncertainty) Δ′17O measurements in an array of diverse Earth materials\, including organics\, sulfates\, phosphates\, nitrates\, carbonates\, silicates\, and waters. The method uses a 3-step process to quantitatively convert sample oxygen to molecular oxygen (O2) for mass spectrometric analysis. Sample oxygen is first converted to oxygen in CO via a high temperature conversion (HTC) furnace (commonly known by the popular Thermo brand “TC/EA”)\, then oxygen in CO is converted to oxygen in water via a Bosch-type methanation reaction\, and finally oxygen in water is converted to O2 by fluorination. In this chapter\, I report the first ever high-precision Δ′17O measurements for organic materials and nitrates along with new measurements for various other standard reference materials.\n\nChapter 3 applies the triple oxygen isotope system to a taxonomically diverse group of mammal teeth from the Early Eocene Willwood Formation of the Bighorn Basin. I use Δ′17O as a tracer for evaporative signals that yield information about the types of water resources each animal used during its life. This chapter offers new insights into the water-use strategies\, dietary preferences\, and habitats of the animals surveyed. I found evidence for semi-aquatic lifestyles in Homogalax and Coryphodon\, while Hyracotherium appeared to be substantially more water independent. Esthonyx and Cantius recorded more variable intermediate Δ′17O values\, potentially suggesting more generalized water-use behaviors in these taxa. \n\nChapter 4 explores the utility of Δ’17O in mammalian teeth to reconstruct biological productivity at the global scale. Here\, I used animal body water models to isolate the Δ′17O signal of respired atmospheric O2 from the fossil mammal teeth sampled in chapter 3. I then leveraged the relationship between global gross primary productivity (GPP) and Δ′17O of atmospheric O2 to reconstruct global GPP. The results from this analysis suggest that global GPP may have been substantially elevated relative to present day\, providing additional context for the state of life during a warm greenhouse world unlike the modern.\n\nThe advances to triple oxygen isotope geochemistry outlined here offer new\, highly versatile methodologies and applications that lay the foundation for routine Δ′17O measurements in a number of new Earth materials. This will fundamentally allow for new investigations into previously underexplored topics in the geosciences and expand our understanding of ancient worlds.

SUMMARY:Workshop / Seminar:Determinantal expressions for Ohyama polynomials
DESCRIPTION:The Ohyama polynomials provide algebraic solutions of the D7 case of the Painleve III equation at a particular sequence of parameter values. It is known that many special function solutions of Painleve equations are expressed in terms of tau functions that can be written in the form of determinants\, but until now such a representation for the Ohyama polynomials was not known. Here we present three different determinantal formulae for these polynomials: the first\, in terms of Wronskian determinants related to a Darboux transformation for a Lax pair of KdV type\; and the second\, in terms of Hankel determinants\, which is related to the Toda lattice. The third is for a slightly modified form of the polynomials and is given as a Wronskian of associated Laguerre polynomials.
