Automatically identifying, counting, and describing wild animals in camera-trap images with deep learning 

Norouzzadeh, Mohammad Sadegh; Nguyen, Anh; Kosmala, Margaret; Swanson, Alexandra; Palmer, Meredith S.; Packer, Craig; Clune, Jeff (2020-07-27)
Having accurate, detailed, and up-to-date information about the location and behavior of animals in the wild would improve our ability to study and conserve ecosystems. We investigate the ability to automatically, accurately, ...

Field‐based robotic phenotyping of sorghum plant architecture using stereo vision 

Bao, Yin; Tang, Lie; Breitzman, Matthew; Salas-Fernandez, Maria; Schnable, Patrick; 0000-0002-3548-1823 (2020-02-24)
Sorghum (Sorghum bicolor) is known as a major feedstock for biofuel production. To improve its biomass yield through genetic research, manually measuring yield component traits (e.g. plant height, stem diameter, leaf angle, ...

No Change in the Recent Lunar Impact Flux Required Based on Modeling of Impact Glass Spherule Age Distributions 

Huang, Ya-Huei; Minton, David A.; Zellner, Nicolle E. B.; Hirabayashi, Masatoshi; Richardson, James E.; Fassett, Caleb I. (2020-05-27)
The distributions of Ar-40/Ar-39-derived ages of impact glass spherules in lunar regolith samples show an excess at <500 Ma relative to older ages. It has not been well understood whether this excess of young ages reflects ...

Sea level rise and inundation of island interiors: Assessing impacts of lake formation and evaporation on water resources in arid climates 

Gulley, J.D.; Mayer, A.S.; Martin, J.B.; Bedekar, V. (2020-04-01)
Coasts of many low-lying islands will be inundated should sea level rise by 1 m by 2100 as projected, thereby decreasing water resources through aquifer salinization. A lesser known impact occurs if rising sea level elevates ...

Noble gas abundance and isotope ratios in the atmosphere of Jupiter from the Galileo Probe Mass Spectrometer 

Mahaffy, PR; Niemann, HB; Alpert, A; Atreya, SK; Demick, J.; Donahue, TM; Harpold, DN; Owen, TC (2020-06-30)
The Galileo Probe Mass Spectrometer provided the first data on the noble gas mixing and isotope ratios in the Jovian atmosphere. These measurements and the comparison with solar values constrain models of Jupiter's formation. ...

Discrimination experiments with the U.S. Army's standard metal detector 

Lloyd, Riggs; Chilaka, Sailaja; Leslie, Collins; Lowe, Larry; Weaver, Richard (2022-10-25)
[1] Discrimination experiments with the U. S. Army's standard hand-held metal detector (AN/PSS-12) are described. An appendix describes the functioning of the device as a metal detector, and the body of the paper discusses ...

The Role of Breccia Lenses in Regolith Generation From the Formation of Small, Simple Craters: Application to the Apollo 15 Landing Site 

Hirabayashi, M; Howl, B; Fassett, C; Soderblom, J; Minton, D; Melosh, H; 0000-0003-1881-1496; 0000-0003-3715-6407; 0000-0003-1656-9704; 0000-0001-9155-3804 (2023-01-18)
Impact cratering is likely a primary agent of regolith generation on airless bodies. Regolith production via impact cratering has long been a key topic of study since the Apollo era. The evolution of regolith due to impact ...

Data for: Comparison of two dielectric sensors in coarse-grained soils of increasing salinity 

Diekmann, Amy; Bowers, Benjamin; Anderson, J. Brian; 0000-0003-1525-4022 (2023-07-12)
Moisture content can impact the resilient modulus of pavement base course and subgrade layers. Given its influence on the post-inundation resilient moduli of the coastal pavement and base course and subgrade layers, it is ...
