Hailed as the perfect musical comedy, this award-winning classic gambles with luck and love under the bright lights of Broadway. "Count me squarely in the Guys and Dolls camp. If there's a flaw to be found in the 1950 'music fable of Broadway,' based on characters created by journalist/short story writer Damon Runyon, it's not in the Jo Swerling and Abe Burrows' drum-tight book. And it's certainly not in Frank Loesser's honey of a score." -New York Stage Review

Title: Reconstructing paleoenvironments using triple oxygen isotope valuesSpeaker: Dr. Jordan Wostbrock, Assistant Professor, Yale UniversityAbstract: The increase of d18O values in the rock record (where older samples have lower d18O values than modern) has been attributed to changing ocean temperature, an increase in the d18O value of the ocean water, or diagenesis obscuring paleoenvironmental information. Unlike conventional δ18O analysis where the formation water’s isotopic value is assumed, paired δ17O-δ18O measurements allow for the water’s isotopic composition to be calculated because there is only one unique solution for equilibrium fractionation using triple oxygen isotope values. This is particularly useful when measuring samples from the rock record, where the water is no longer present. These measurements are also useful for a definitive identification of diagenesis – samples that fall off the unique triple oxygen isotope equilibrium curve must have undergone some degree of diagenesis. A fluid-rock mixing model can be used to ‘see through’ alteration in samples such that the initial temperature of formation and the oxygen isotope value of the water in which the carbonate formed can be calculated. In this talk, I will present the first carbonate-water triple oxygen isotope equilibrium curve. I will then use the equilibrium curve to compare the triple oxygen isotope values of Phanerozoic brachiopods. Lastly, I will present results from carbonate concretions from the Late Cretaceous Western Interior Seaway that combines triple oxygen isotope measurements with carbonate clumped isotope measurements (D47 values) to better understand the diagenetic history of the carbonate concretions.

AI and Data Forum with PizzaHosted by the URI Innovation Lab and the Center for Computational Research (CCR)Friday April 18, 2025 Noon – 1:30Two teams that received 2024 CCR (Center for Computational Research) Seed Funding will present outcomes from their convergent/interdisciplinary and data enhanced projects. These presentations will highlight the importance of teams of experts from multiple disciplines to solve the difficult data informed problems of our times. Students, Faculty and Staff from all disciplines are welcome.Advanced statistical modeling in pharmacoepidemiology research to access opioid safety during pregnancy - Associate Professor Sheron (Xuerong) Wen (Pharmacy Practice) and Associate Professor Yichi Zhang (Statistics)The team has conducted Bayesian mediation analyses to identify the mediators and estimate the natural direct and indirect effects of prenatal opioid exposure on long-term neurodevelopmental outcomes. Further advanced statistical modeling was developed and implemented to examine the direct and indirect interaction effects of concomitant use of prescription opioids and antidepressants in pregnant women on neurodevelopment in their offspring.Development of deep learning models for biological data classification - Associate Professor Ying Zhang (CMB, CELS) and Professor Drew Zhang (College of Business)The team has conducted the following: (1) a comparative study of different deep-learning architectures (i.e. BERT, CNN, and LSTM) and their accuracy in classifying sequencing reads from multiple species; (2) the application of large language models for the classification of DNA sequences.
