Binary Information from Open Clusters Using SEDS (BINOCS) Project: The Dynamical Evolution of the Binary Populations in Cluster Environments
Peter Frinchaboy, Benjamin Thompson
Studying the internal dynamics of stellar clusters is conducted primarily through N-Body simulations. One of the major inputs into N-Body simulations is the binary star frequency a…
Measuring the Prevalence of Policy Violating Content with ML Assisted Sampling and LLM Labeling
Attila Dobi, Aravindh Manickavasagam, Benjamin Thompson +2
Content safety teams need metrics that reflect what users actually experience, not only what is reported. We study prevalence: the fraction of user views (impressions) that went to…
Test-retest Reliability of Psychophysical Tasks Using Structured Light-Induced Entoptic Phenomena
Taranjit Singh, Mukhit Kulmaganbetov, Zhangting Wang +8
Structured light (SL)-induced polarization perception presents a promising method for the early detection of macular diseases such as age-related macular degeneration. We investiga…
Characterizing the circularly-oriented macular pigment using spatiotemporal sensitivity to structured light entoptic phenomena
Dmitry A. Pushin, Davis V. Garrad, Connor Kapahi +9
The macular pigment (MP) in the radially-oriented Henle fibers that surround the foveola enables the ability to perceive the orientation of polarized blue light through an entoptic…
Chemical abundance gradients from open clusters in the Milky Way disk: results from the APOGEE survey
Katia Cunha, Peter M. Frinchaboy, Diogo Souto +23
Metallicity gradients provide strong constraints for understanding the chemical evolution of the Galaxy. We report on radial abundance gradients of Fe, Ni, Ca, Si, and Mg obtained…
The Binary INformation from Open Clusters Using SEDs (BINOCS) Project: Reliable Photometric Mass Determinations of Binary Star Systems in Clusters
Benjamin Thompson, Peter M. Frinchaboy, Taylor Spoo +1
We introduce a new binary detection technique, Binary INformation from Open Clusters using SEDs (binocs), which we show is able to determine reliable stellar multiplicity and masse…
The Apache Point Observatory Galactic Evolution Experiment (APOGEE)
Steven R. Majewski, Ricardo P. Schiavon, Peter M. Frinchaboy +75
The Apache Point Observatory Galactic Evolution Experiment (APOGEE), one of the programs in the Sloan Digital Sky Survey III (SDSS-III), has now completed its systematic, homogeneo…
The Open Cluster Chemical Analysis and Mapping Survey: Local Galactic Metallicity Gradient with APOGEE using SDSS DR10
Peter M. Frinchaboy, Benjamin Thompson, Kelly M. Jackson +31
The Open Cluster Chemical Analysis and Mapping (OCCAM) Survey aims to produce a comprehensive, uniform, infrared-based dataset for hundreds of open clusters, and constrain key Gala…
The Open Cluster Chemical Abundances and Mapping Survey: II. Precision Cluster Abundances for APOGEE using SDSS DR14
John Donor, Peter M. Frinchaboy, Katia Cunha +12
The Open Cluster Chemical Abundances and Mapping (OCCAM) survey aims to produce a comprehensive, uniform, infrared-based spectroscopic dataset for hundreds of open clusters, and to…
Topological Expansion of Boehm's Brushes via Structured Light
Dmitry A. Pushin, Iman Salehi, Amy Chow +10
We report a novel entoptic phenomenon in which the classical two-lobed Boehm's brushes are transformed into a multi-lobed structure by projecting spin-orbit coupled light onto the…
High precision control and deep learning-based corn stand counting algorithms for agricultural robot
Zhongzhong Zhang, Erkan Kayacan, Benjamin Thompson +1
This paper presents high precision control and deep learning-based corn stand counting algorithms for a low-cost, ultra-compact 3D printed and autonomous field robot for agricultur…
Khovanov complexes of rational tangles
Benjamin Thompson
We show that the Khovanov complex of a rational tangle has a very simple representative whose backbone of non-zero morphisms forms a zig-zag. Furthermore, this minimal complex can…
