Large Language Model‐Based Chatbots in Higher Education

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The use of large language models (LLMs) in higher education can facilitate personalized learning experiences, advance asynchronized learning, and support instructors, students, and researchers across diverse fields. The development of regulations and guidelines that address ethical and legal issues is essential to ensure safe and responsible adaptation

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

Astronomische Nachrichten, EarlyView.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Streamlets within meteoroid streams on NEA orbits [PDF]

Geofísica Internacional, 2008
Five meteoroid streams of apparent asteroidal nature have been identified in the IAU_MDC Database of Photographic Meteors. Three streams contain streamlets, composed of two or more meteoroids sharing nimpact rate on the NEA population by objects 1 m or ...

Cratering of a comet nucleus by meteoroids [PDF]

Advances in Space Research, 1999
Abstract The two-dimensional axisymmetric hydrocode model of free particles is applied to the calculation of response of a comet nucleus to a meteorite impact. The nucleus is assumed to be spherical with a radius of 1 km. It is composed of a porous granular mixture of water ice and of mineral. Initial temperature is 50 K.

Cheek tooth extraction in geriatric versus non‐geriatric horses

Equine Veterinary Journal, EarlyView.
Abstract Background Age‐related dental changes are major contributors to dental disorders in older horses, and cheek tooth extractions are often required to maintain masticatory function and oral comfort. However, limited information is available on clinical and treatment characteristics in this older patient population.

Meteor fluxes and visual magnitudes from EISCAT radar event rates: a comparison with cross-section based magnitude estimates and optical data [PDF]

Annales Geophysicae, 1998
Incoherent scatter radars (ISR) are versatile instruments for continuous monitoring of ionisation processes in the Earth's atmosphere. EISCAT, The European Incoherent Scatter facility has proven effective also in meteor studies. The time resolution of

Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

Geological Journal, EarlyView.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

The Spectrum and Orbit of a Fireball Producing Mesospheric Irregularity and Implications for Meteor Mass Deposition

The Astrophysical Journal, 2023
The physical properties of meteoroids producing meteor plasma non-field-aligned irregularities (NFAI) in the Earth’s atmosphere are poorly known. Here we report a complete picture of a fireball and mesospheric NFAI that it produced for the first time ...

Incidental Detection of Portal Venous Gas During POCUS in a Neonate With Necrotizing Enterocolitis and Intestinal Perforation: A Case Report

Journal of Clinical Ultrasound, EarlyView.
Point‐of‐care ultrasound performed at the bedside identified hepatic portal venous gas in a critically ill neonate, prompting urgent evaluation and revealing intestinal perforation due to necrotizing enterocolitis. This case highlights the potential of POCUS to accelerate diagnosis when clinical signs are subtle or nonspecific.

Exclusive Seismoacoustic Detection and Characterization of an Unseen and Unheard Fireball Over the North Atlantic

Geophysical Research Letters, 2023
Small meteoroids that enter Earth's atmosphere often go unnoticed because their detection and characterization rely on human observations, introducing observational biases in space and time.
