The Orbital Architecture of Qatar-6: A Fully Aligned Three-body System? [PDF]

open access: goldThe Journal of Chemical Physics, 2023
A new tensor expansion of the orbit–orbit interaction is derived straightforwardly in a form which is compact and completely symmetric in the coordinates of interacting particles. The m-scheme matrix element of the orbit–orbit interaction is then obtained as a concise sum of radial integrals.

A Rare Case of Direct Spontaneous Carotid-Cavernous Fistula in a 6-Month-Old Infant and Review of the Literature

open access: yesCase Reports in Ophthalmology, 2023
Direct or type A CCFs are the direct connection between the cavernous segment of the internal carotid artery and the cavernous sinus. While most direct CCFs are caused by trauma, spontaneous direct CCFs are extremely rare in infants.

UAS Mapping as an alternative for land surveying techniques? [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
Can a UAS mapping technique compete with standard surveying techniques? Since the boom in different RPAS (remotely piloted air system), UAV (unmanned aerial vehicle), or UAS (unmanned aerial system), this is one of the crucial questions when it comes to ...

Orbital Lymphoma Masquerading as Orbital Cellulitis [PDF]

open access: yesCase Reports in Ophthalmological Medicine, 2021
Background. Orbital lymphomas are primarily non-Hodgkin type and can originate from the eyelids, extraocular muscles, soft tissue orbital adnexa, conjunctiva, or lacrimal glands. Orbital malignancies often represent a diagnostic dilemma for clinicians given their varying and atypical presentations. Objective.
