The State of Astronomy Education in the U.S.

open access: yes, 1996
I would like to set the scene for the discussion that will follow in this book and bring up a few disturbing points which I believe any discussion about astronomy education will ultimately have to address.

Must Longtermists Wish Us All Dead? A Quadrilemma

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Longtermists assign great moral importance to making the long‐term future as good as possible, especially by ensuring the survival of humanity. We argue, to the contrary, that on assumptions that are plausible, conservative, or shared by leading longtermists, human extinction will likely augment total utility among human and non‐human animals ...

AstroInspect: A Web-based System to Organize, Assess, and Visually Inspect Astronomical Objects

open access: yesThe Astronomical Journal
The rapid growth of imaging and spectroscopic surveys has intensified the need for efficient tools that support visual inspection, a practice that remains essential for tasks such as classification, catalog refinement, and validation of automated methods.

Assessment of Human Thermal Stress Dynamics and Regional Drivers Across the Arabian Peninsula During 1990–2022 From Observations

open access: yesInternational Journal of Climatology, EarlyView.
The results reveal that thermal stress varies substantially across the four AP regions, with winter cold stress in Region I, year‐round heat stress in Region II, pronounced summer heat stress in Region III, and persistent strong to very strong heat stress from late spring to early autumn in Region IV.

Exploring women's experiences and perceptions regarding the pharmacological management of hyperemesis gravidarum: a qualitative study

open access: yesJournal of Pharmacy Practice and Research, EarlyView.
Abstract Background Hyperemesis gravidarum (HG) is a severe form of nausea and vomiting in pregnancy with potential sequelae including hypovolaemia, electrolyte imbalance, and malnutrition, which can result in adverse maternal–foetal outcomes. Aim To explore Australian women's experiences and perceptions regarding the pharmacological management of HG ...

Managing and visualising geochemical data for tephra correlation with the IntChron Integration Tool

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT There is now a wealth of glass‐shard geochemical data for volcanic ash (tephra) layers from a wide range of volcanoes and eruptions, providing invaluable datasets for tephrochronology. However, compilation of published data to assess tephra correlations leads to large files and requires careful management.

GERBLS—A Rapid Box Least Squares Algorithm for Exoplanet Detection That Scales Well for Large Datasets

open access: yesThe Astronomical Journal
Box least squares (BLS) is a robust but computationally expensive method to search for transits in photometric data. Reducing its computational cost is especially relevant when scanning large datasets or conducting transit injection and recovery ...

Multispectral Mid‐Infrared Imaging With Incoherent Light via Adiabatic Upconversion

open access: yesLaser &Photonics Reviews, EarlyView.
We demonstrate room‐temperature broadband MIR imaging based on adiabatic frequency upconversion, driven by a Q‐switched pump laser and incoherent illumination. The small‐foot‐print system upconverts the spectral range to the visible domain, without scanning, thermal control and with spatial resolution below 20μm$20\mathrm{\mu}\mathrm{m}$.
