    Lava River Cave IMU (Moasure) Traverse
    (2025) Wang, Jingchuan; Schmerr, Nicholas; Porter, Ryan; Whelley, Patrick
    Lava River Cave near Flagstaff, Northern Arizona, is a lava tube approximately 1.25 km long and 15 m wide. The cave has been previously mapped by manual sketching and, recently, mobile light detection and ranging (LiDAR; King et al., 2023). However, large discrepancies remain in the absolute positioning of the cave passage, likely owing to poor GPS reception in the pine forest. To address this inconsistency, we performed a 350 m traverse of the cave passage starting at the cave entrance and ending at the pillar where the tube bifurcates and reconnects, while tracking the movement using a Moasure 2 PRO, a motion-based measuring tool (inertial measurement unit). The resulting 3D spatial dataset in Cartesian coordinates was then georeferenced using a straight path north of the cave and the nearby parking lot as base stations.

    Insoluble Acyclic Cucurbit[n]uril-Type Receptors Capture Iodine from the Vapor Phase
    (Wiley: Chemistry European Journal, 2024-09-27) Perera, Suvenika; Shaurya, Alok; Zeppuhar, Andrea; Chen, Fu; Zavalij, Peter Y.; Gaskell, Karen; Isaacs, Lyle; Isaacs, Lyle
    Nuclear energy makes large contributions toward meeting global energy needs, but societal concerns remain high given the impacts of the intended release of radioactive materials including 129I and 131I. In this paper we explore the use of a homologous series of acyclic CB[n] type hosts (H1–H4) as adsorbents of iodine from the vapor phase. We find that H2–H4, but not H1 – perform well in this application with uptake capacities of 2.2 g g−1, 1.5 g g−1, and 1.9 g g−1, respectively. The chemisorptive uptake process involves partial oxidation of catechol walled H2 to quinone walled host and capture of I3− and I5−. Solid H2 can be regenerated by treatment with Na2S2O4 and reused at least five times. The x-ray crystal structure of H2 is also reported.

    A Swarm of WASP Planets: Nine giant planets identified by the WASP survey
    (2025) Schanche, Nicole
    The Wide Angle Search for Planets (WASP) survey provided some of the first transiting hot Jupiter candidates. With the addition of the Transiting Exoplanet Survey Satellite (TESS), many WASP planet candidates have now been revisited and given updated transit parameters. In the accompanying paper, we present 9 transiting planets orbiting FGK stars that were identified as candidates by the WASP survey and measured to have planetary masses by radial velocity measurements. Subsequent space-based photometry taken by TESS as well as ground-based photometric and spectroscopic measurements have been used to jointly analyze the planetary properties of WASP-102 b, WASP-116 b, WASP-149 b WASP-154 b, WASP-155 b, WASP-188 b, WASP-194 b/HAT-P-71 b, WASP-195 b, and WASP-197 b. These planets have radii between 0.9 R_Jup and 1.4 R_Jup, masses between 0.1 M_Jup and 1.5 M_Jup, and periods between 1.3 and 6.6 days.

    Active Seismic Exploration of Planetary Subsurfaces via Compressive Sensing
    (2025) Wang, Jingchuan; Schmerr, Nicholas; Lekic, Vedran
    The software supports the following study: We present a method for improving seismic data collection on planetary surfaces such as the Moon and Mars. This approach is based on recent advances in compressive sensing technology to reduce the number of data collection points required compared to conventional methods without sacrificing the quality of the resulting subsurface images. We demonstrate its effectiveness using both synthetic and field data from locations with similarities to planetary surface environments. The method is then applied to reanalyze seismic data collected by the crew of the Apollo 14 and 16 missions. Our study has implications for mission planning, as this method can make space missions more efficient by reducing the equipment and time to collect geophysical data on planetary surfaces. It also makes it possible to reconstruct missing or damaged data, improving the quality of imagery and enhancing our understanding of the interior of other worlds.
