Echogenic foci with comet-tail artifact in resected thyroid nodules: Not an absolute predictor of benign disease. [PDF]
PLoS ONE, 2018 The purpose of this study was to evaluate the frequency of echogenic foci with comet-tail artifact in histologically proven thyroid nodules, and to determine the types of echogenic foci with comet-tail artifact that are associated with malignancy.

Comet tail artifact on ultrasonography: is it a reliable finding of benign gallbladder diseases? [PDF]
Ultrasonography, 2019 Purpose The aim of this study was to evaluate whether the comet tail artifact on ultrasonography can be used to reliably diagnose benign gallbladder diseases. Methods This retrospective study reviewed the clinical findings, imaging findings, preoperative

Blasting off on an actin comet tail. [PDF]
PLoS Biology, 2009 CellsCells have structure and the ability to move, thanks in part to the actin cytoskeleton, a dynamic cellular scaffolding that facilitates many cellular processes. Actin is mostly concentrated near the outer membrane of the cell, where it is involved in such processes as the formation of membrane protrusions at the leading edges of migrating cells ...

COMET Flows: Towards Generative Modeling of Multivariate Extremes and Tail Dependence [PDF]
arXiv, 2022 Normalizing flows, a popular class of deep generative models, often fail to represent extreme phenomena observed in real-world processes. In particular, existing normalizing flow architectures struggle to model multivariate extremes, characterized by heavy-tailed marginal distributions and asymmetric tail dependence among variables.

The Scintillating Tail of Comet C/2020 F3 (Neowise) [PDF]
A&A 667, A57 (2022), 2022 Context. The occultation of a radio source by the plasma tail of a comet can be used to probe structure and dynamics in the tail. Such occultations are rare, and the occurrence of scintillation, due to small-scale density variations in the tail, remains somewhat controversial. Aims. A detailed observation taken with the Low-Frequency Array (LOFAR) of a

Study of the April 20, 2007 CME-Comet Interaction Event with an MHD Model [PDF]
Astrophys.J.696:L56-L60,2009, 2009 This study examines the tail disconnection event on April 20, 2007 on comet 2P/Encke, caused by a coronal mass ejection (CME) at a heliocentric distance of 0.34 AU. During their interaction, both the CME and the comet are visible with high temporal and spatial resolution by the STEREO-A spacecraft.

Novel automatic detection of pleura and B-lines (comet-tail artifacts) on in vivo lung ultrasound scans [PDF]
SPIE Medical Imaging, 2016 This paper presents a novel automatic method for detection of B-lines (comet-tail artifacts) in lung ultrasound scans. B-lines are the most commonly used artifacts for analyzing the pulmonary edema.
