On the Nature of the Emission of the Crab Nebula [PDF]

Symposium - International Astronomical Union, 1958
The emission of the Crab Nebula is perhaps connected with the internal motions of the gas. As shown by the observations, the power of the emission sources differs by some hundred times in different points of the amorphous mass (“wisps” and other details).

Oxygen isotope thermometry and composition of aqueous fluids within the parent body of asteroid (101955) Bennu

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2567-2591, October 2026.
Abstract We report on the petrography and oxygen isotopic compositions from in situ analyses of carbonates (Ca‐carbonate, dolomite, and Fe‐rich magnesite), magnetite, and apatite in particles from asteroid Bennu. Using oxygen isotope thermometry of Ca‐carbonate, dolomite, and magnetite, we estimated crystallization temperatures and the oxygen isotopic ...

A Systems‐Level Approach to Address Risks and Ethics in Artificial Intelligence Systems

Systems Engineering, Volume 29, Issue 5, Page 793-806, September 2026.
ABSTRACT Artificial intelligence (AI) is rapidly changing the world, from completely controlling routine or mundane tasks like text and image generation, to powering advanced algorithms that control critical systems. The recent advances in generative AI quickly overwhelmed multiple industries from education to finance as first adopters rushed (and ...

Optical observations of the nearby galaxy IC342 with narrow band [SII] and Hα filters. I [PDF]

Serbian Astronomical Journal, 2013
We present observations of a portion of the nearby spiral galaxy IC342 using narrow band [SII] and Hα filters. These observations were carried out in November 2011 with the 2m RCC telescope at Rozhen National Astronomical Observatory in Bulgaria.

Addressing Food Insecurity on College Campuses: From Charity to Social Responsibility Framing

Business and Society Review, Volume 131, Issue 3, Fall 2026.
ABSTRACT The concept of social responsibility has increasingly become relevant for colleges and universities, entities that mirror businesses in their community power and centrality. Increased calls for colleges and universities to attend to social issues frequently emphasize issues of access and affordability, campus sustainability, and the promotion ...

MAMMOTH-Subaru. II. Diverse Populations of Circumgalactic Lyα Nebulae at Cosmic Noon

The Astrophysical Journal Supplement Series
Circumgalactic Ly α nebulae are gaseous halos around galaxies exhibiting luminous extended Ly α emission. This work investigates Ly α nebulae from deep imaging of ∼12 deg ^2 sky, targeted by the MAMMOTH-Subaru survey.

Maser emission in planetary nebulae [PDF]

Proceedings of the International Astronomical Union, 2007
AbstractStars at the top of the asymptotic giant branch (AGB) can exhibit maser emission from molecules like SiO, H2O and OH. These masers appear in general stratified in the envelope, with the SiO masers close to the central star and the OH masers farther out in the envelope.

Catch Me If You Can: The Dynamic Nature of Bias in Machine Learning Applications

Information Systems Journal, Volume 36, Issue 5, Page 710-742, September 2026.
ABSTRACT Bias in machine learning (ML) applications represents systematic differences between expected and actual values of the predicted outputs, such that certain individuals or groups are systematically and disproportionately (dis)advantaged. This paper investigates the dynamic nature of bias in ML applications.
