The Sixteenth Data Release of the Sloan Digital Sky Surveys: First Release from the APOGEE-2 Southern Survey and Full Release of eBOSS Spectra
Romina Ahumada, Carlos Allende Prieto, Andres Almeida +310
This paper documents the sixteenth data release (DR16) from the Sloan Digital Sky Surveys; the fourth and penultimate from the fourth phase (SDSS-IV). This is the first release of…
Associations between learning assistants, passing introductory physics, and equity: A quantitative critical race theory investigation
Ben Van Dusen, Jayson Nissen
Many STEM degrees require passing an introductory physics course. Physics courses often have high failure rates that may disproportionately harm students who are marginalized by ra…
Alternating knots with large boundary slope diameter
Masaharu Ishikawa, Thomas W. Mattman, Kazuya Namiki +1
We show that, for an alternating knot, the ratio of the diameter of the set of boundary slopes to the crossing number can be arbitrarily large.
Two-bridge knots admit no purely cosmetic surgeries
Kazuhiro Ichihara, In Dae Jong, Thomas W. Mattman +1
We show that two-bridge knots and alternating fibered knots admit no purely cosmetic surgeries, i.e., no pair of distinct Dehn surgeries on such a knot produce 3-manifolds that are…
Confirmatory Aspect-based Opinion Mining Processes
Jongho Im, Taikgun Song, Youngsu Lee +1
A new opinion extraction method is proposed to summarize unstructured, user-generated content (i.e., online customer reviews) in the fixed topic domains. To differentiate the curre…
Quasi-Noether systems and quasi-Lagrangians
V. Rosenhaus, Ravi Shankar
We study differential systems for which it is possible to establish a correspondence between symmetries and conservation laws based on Noether identity: quasi-Noether systems. We a…
