Subsurface temperature estimates from a Regional Ocean Modelling System (ROMS) reanalysis provide accurate coral heat stress indices across the Main Hawaiian Islands

Autor: Jessica N. Perelman, Kisei R. Tanaka, Joy N. Smith, Hannah C. Barkley, Brian S. Powell

Publikováno v: Scientific Reports, Vol 14, Iss 1, Pp 1-13 (2024)

Abstract As ocean temperatures continue to rise, coral bleaching events around the globe are becoming stronger and more frequent. High-resolution temperature data is therefore critical for monitoring reef conditions to identify indicators of heat str

Microbial community dynamics and cycling of plutonium and iron in a seasonally stratified and radiologically contaminated pond

Autor: Nancy Merino, Naomi L. Wasserman, Fanny Coutelot, Daniel I. Kaplan, Brian A. Powell, Yongqin Jiao, Annie B. Kersting, Mavrik Zavarin

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-15 (2023)

Abstract Plutonium (Pu) cycling and mobility in the environment can be impacted by the iron cycle and microbial community dynamics. We investigated the spatial and temporal changes of the microbiome in an iron (Fe)-rich, plutonium-contaminated, monom

Sources, seasonal cycling, and fate of plutonium in a seasonally stratified and radiologically contaminated pond

Autor: Naomi L. Wasserman, Nancy Merino, Fanny Coutelot, Daniel I. Kaplan, Brian A. Powell, Annie B. Kersting, Mavrik Zavarin

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-12 (2023)

Abstract Unlike short-term laboratory experiments, studies at sites historically contaminated with radionuclides can provide insight into contaminant migration behavior at environmentally-relevant decadal timescales. One such site is Pond B, a season

Nutricline adjustment by internal tidal beam generation enhances primary production in idealized numerical models

Autor: Jasen R. Jacobsen, Christopher A. Edwards, Brian S. Powell, John A. Colosi, Jerome Fiechter

Publikováno v: Frontiers in Marine Science, Vol 10 (2023)

When the barotropic tide encounters variable bathymetry, fluctuating flow along a topographic slope generates baroclinic tides, or internal tides. There is growing evidence that these internal tides can affect primary production in the euphotic zone,

Short-period Variables in TESS Full-frame Image Light Curves Identified via Convolutional Neural Networks

Autor: Greg Olmschenk, Richard K. Barry, Stela Ishitani Silva, Jeremy D. Schnittman, Agnieszka M. Cieplak, Brian P. Powell, Ethan Kruse, Thomas Barclay, Siddhant Solanki, Bianca Ortega, John Baker, Mamani Yesenia Helem Salinas

Publikováno v: The Astronomical Journal, Vol 168, Iss 2, p 83 (2024)

The Transiting Exoplanet Survey Satellite (TESS) mission measured light from stars in ∼85% of the sky throughout its 2 yr primary mission, resulting in millions of TESS 30-minute-cadence light curves to analyze in the search for transiting exoplane

Role-based lateral movement detection with unsupervised learning

Autor: Brian A. Powell

Publikováno v: Intelligent Systems with Applications, Vol 16, Iss , Pp 200106- (2022)

Adversarial lateral movement via compromised accounts remains difficult to discover via traditional rule-based defenses because it generally lacks explicit indicators of compromise. We propose a behavior-based, unsupervised method of lateral movement

Transiting Exoplanet Yields for the Roman Galactic Bulge Time Domain Survey Predicted from Pixel-level Simulations

Autor: Robert F. Wilson, Thomas Barclay, Brian P. Powell, Joshua Schlieder, Christina Hedges, Benjamin T. Montet, Elisa Quintana, Iain Mcdonald, Matthew T. Penny, Néstor Espinoza, Eamonn Kerins

Publikováno v: The Astrophysical Journal Supplement Series, Vol 269, Iss 1, p 5 (2023)

The Nancy Grace Roman Space Telescope (Roman) is NASA’s next astrophysics flagship mission, expected to launch in late 2026. As one of Roman’s core community science surveys, the Galactic Bulge Time Domain Survey (GBTDS) will collect photometric
