Gas Sources from the Coma and Nucleus of Comet 46P/Wirtanen Observed Using ALMA
Gas-phase molecules in cometary atmospheres (comae) originate primarily from (1) outgassing by the nucleus, (2) sublimation of icy grains in the near-nucleus coma, and (3) coma (photo)chemical processes.

Phase Curves of Kuiper Belt Objects, Centaurs, and Jupiter-family Comets from the ATLAS Survey
The Kuiper Belt objects (KBOs), the Centaurs, and the Jupiter-family comets (JFCs) form an evolutionary continuum of small outer solar system objects, and their study allows us to gain insight into the history and evolution of the solar system. Broadband

The magnitude distribution and evolution of short-period comets [PDF]
The magnitude distribution, perihelion distribution, nucleus size variation and evolution of the short-period comet population are re-assessed. Short-period comets with perihelion distances greater than 2 au have a magnitude distribution index of about 2.3, similar to that of the long-period comets.

Dose‐Related Gastric Toxicity of Diethyl Phthalate in Female Wistar Rats
ABSTRACT Diethyl phthalate (DEP) is commonly used in cosmetics, personal care products, and pharmaceutical formulations as a low‐molecular‐weight phthalate. Despite its widespread use, information on its effects on the gastric mucosa remains limited. This study examined the dose‐related effects of DEP on inflammation, oxidative stress, gastric mucosal ...

Use of ultrasonography in assessing peri‐implant osseous defects: An in vitro study
Abstract Background The purpose of this study is to investigate the feasibility and diagnostic accuracy of ultrasonography in peri‐implant defect identification and evaluation, and to compare ultrasonography (USG) with cone‐beam computed tomography (CBCT) in defect identification and evaluation in an in vitro model.
