Abstract If a spacecraft loses contact with Earth, ground‐based observatories can collect observations to assist the recovery effort by providing information on spacecraft location and state. Optical observations converted to a light curve of spacecraft magnitude over time show the spin period and/or orientation of the spacecraft.

Abstract It is important to be able to accurately predict geoelectric field behavior so that potential space weather hazards to large grounded infrastructure, such as electric power grids, smart grids, oil and gas pipelines, and railway systems, can be better understood.

Trading Zones Between Thick and Thin: Anthropological Description as Scaffold or Mosaic
ABSTRACT Referring to the work of historian of science Peter Galison, I argue that anthropology requires thin description as an essential counterpart for thick description. Thin accounts provide the scaffolding within which thick descriptions sit. Galison uses the idea of a “trading zone” connecting different communities who, despite their differences (

Heterogeneity of iridoid biosynthesis in catmints: Molecular background in a phylogenetic context
Evolutionary gains and losses of key biosynthetic genes likely resulting from multiple independent evolutionary events explain why certain Nepeta (catnip) species produce both the active, cat‐attracting nepetalactones and sugar‐bound iridoids, while others make only the sugar‐bound forms, and some have lost iridoid production entirely.

Abstract The probability density function of drops is difficult to model. Current approaches make assumptions that are often problematic, as they allow negative values for the mean of the distribution. While the statistical goodness of fit of those models might be reasonable for precipitation radar estimation, the situation is unsatisfactory if a fully
