Orbital Lymphoma Masquerading as Orbital Cellulitis [PDF]
Case 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.

Orbital Rhabdomyosarcoma [PDF]
Cancer Control, 2004 Although rhabdomyosarcoma (RMS) is a rare tumor among the entire group of mesenchymal malignancies, it is a relatively common lesion and significant challenge for the ocular oncologist in terms of its diagnosis and management.A comprehensive literature search of articles published over the past 30 years in PubMed was conducted.Orbital RMS usually ...

A Star Sensor On-Orbit Calibration Method Based on Singular Value Decomposition
Sensors, 2019 The navigation accuracy of a star sensor depends on the estimation accuracy of its optical parameters, and so, the parameters should be updated in real time to obtain the best performance. Current on-orbit calibration methods for star sensors mainly rely

Observation of two distinct cold, dense ion populations at geosynchronous orbit: Local time asymmetry, solar wind dependence and origin [PDF]
, 2006 International audienceWe report on the observation of two distinct cold (TiNi>2 cm?3) ion populations at geosynchronous orbit. A statistical study was performed on measurements from the geosynchronous Los Alamos plasma instruments, for the period 1990 ...

Actinomycosis of the Orbit [PDF]
Ophthalmic Plastic & Reconstructive Surgery, 1992 Actinomycosis is a very rare cause of orbital abscess usually attributable to direct spread from adjacent structures. A case of actinomycosis of the orbit is presented, which was treated as orbital pseudotumour for 3 months before progression of signs and symptoms, despite high dose steroids, led to the diagnosis being reconsidered.

Extension of the sun-synchronous Orbit
, 2010 Through careful consideration of the orbit perturbation force due to the oblate nature of the primary body a secular variation of the ascending node angle of a near-polar orbit can be induced without expulsion of propellant.

LMS Journal of Computation and Mathematics, 2004 AbstractThis paper contains a variety of results about the action of Con way‘s largest simple group upon the crosses in the Leech lattice. These results are tailor-made for use in ‘A Monster Graph, I'(Proc. London Math. Soc. (3) 90 (2005) 42-60), where a graph related to the Monster simple group is studied.
