Concurrency and Computation: Practice and Experience, Volume 35, Issue 11, 15 May 2023., 2023 Summary Graphics processing units (GPUs) are unarguably vital to keep up with the perpetually growing demand for compute capacity of data‐intensive applications. However, the overhead of transferring data between host and GPU memory is already a major limiting factor on the single‐node level. The situation intensifies in scale‐out scenarios, where data

Suspending failure: temporalities, ontologies, and gigantism in fusion energy development
Journal of the Royal Anthropological Institute, Volume 29, Issue S1, Page 114-132, April 2023., 2023 Abstract Tracing the history of terrestrial fusion energy to a giant multinational experimental fusion facility under construction reveals a series of consequential failures, re‐evaluations of once defunct designs, but also persistence. To account for how this vast enterprise, dogged by failure, endures, I suggest that different ontological narratives ...

PHANGS–JWST First Results: Duration of the Early Phase of Massive Star Formation in NGC 628
The Astrophysical Journal Letters, 2023 The earliest stages of star formation, when young stars are still deeply embedded in their natal clouds, represent a critical phase in the matter cycle between gas clouds and young stellar regions.

On-orbit performance of the Spitzer Space Telescope [PDF]
SPIE Proceedings, 2004 The Spitzer Space Telescope (formally known as SIRTF) was successfully launched on August 25, 2003, and has completed its initial in-orbit checkout and science validation and calibration period. The measured performance of the observatory has met or exceeded all of its high-level requirements, it has entered normal operations, and is beginning to ...

Progress in Diamanes and Diamanoids Nanosystems for Emerging Technologies
Advanced Science, Volume 9, Issue 11, April 14, 2022., 2022 Diamanes and diamanoids are newly discovered graphitic carbon nanostructures. These nanosystems are sp3 carbon networks along with few sp2 hybridized carbon atoms which can be fabricated under controlled temperature & pressure using graphitic system as a precursor.

Visible to Mid‐Infrared Optical Constants of Orthopyroxenes
Earth and Space Science, Volume 9, Issue 4, April 2022., 2022 Abstract Radiative transfer models of remotely acquired infrared spectra result in quantitative identification of minerals on planetary surfaces. Optical constants, or the real (n) and imaginary (k) indices of refraction are necessary inputs in such models.

An investigation of open cluster Melotte 72 using Gaia DR2
Astronomische Nachrichten, Volume 342, Issue 4, Page 613-624, May 2021., 2021 Abstract The estimation of the main parameters of star clusters is significant in astrophysical studies. The most important aspect of using the Gaia DR2 survey lies in the positions, parallax, and proper motions of cluster stars with homogeneous photometry that make the membership probability determine with high accuracy.

1I/‘Oumuamua as an N2 Ice Fragment of an exo‐Pluto Surface: I. Size and Compositional Constraints
Journal of Geophysical Research: Planets, Volume 126, Issue 5, May 2021., 2021 Abstract The origin of the interstellar object 1I/‘Oumuamua has defied explanation. We perform calculations of the non‐gravitational acceleration that would be experienced by bodies composed of a range of different ices and demonstrate that a body composed of N2 ice would satisfy the available constraints on the non‐gravitational acceleration, size ...

The high-redshift Universe with Spitzer [PDF]
Nature Astronomy volume 4, pages 478-485 (2020), 2020 When did galaxies start forming stars? What is the role of distant galaxies in galaxy formation models and the epoch of reionization? What are the conditions in typical star-forming galaxies at redshifts >~4? Why is galaxy evolution dependent on environment? The Spitzer Space Telescope has been a crucial tool for addressing these questions.
