Iterative Silver-Label Refinement For Temporal Information Extraction In Biomedical Literature, Chan Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Temporal information extraction plays a critical role in the biomedical domain, where the ability to identify events and their temporal relationships is central to interpreting research findings. However, annotated corpora for this task remain scarce and costly to produce and the existing models developed for clinical text do not transfer well. This work bridges that gap through iterative silver-label refinement. A temporal model originally trained on news-domain data is adapted to biomedical text through cycles of automatic labeling, targeted correction, and retraining without the need for comprehensive manual annotation.

Key contributions include a practical iterative refinement methodology demonstrating that the …

Precise Kinetic Parameters For Thermal Resetting Of Clumped Isotope Signatures In Biogenic And Abiogenic Calcites, Nico Kueter, Nathan Looser, Jordon D. Hemingway, Nils B. Gies, Gregory D. Price, Alberto Perez-Huerta, Stefano M. Bernasconi

School of Geography, Earth and Environmental Sciences

Carbonate clumped isotope (∆₄₇) thermometry is a powerful tool to reconstruct paleotemperatures. However, episodes of heating or cooling can alter original ∆₄₇ values through diffusive C-O bond reordering—i.e., isotopic exchange between neighboring carbonate groups within the mineral lattice—and/or oxygen-isotope exchange between carbonate groups and water (collectively termed “thermal resetting”). Nevertheless, if precise kinetic constraints are available, altered ∆₄₇ values can be utilized to reconstruct thermal histories of sedimentary basins or to restore primary ∆₄₇ values from carbonates which experienced thermal resetting in their geological history. Here, we present new high-resolution heating experiments on optical (abiogenic) …
