The first observed stellar occultations by the irregular satellite Phoebe (Saturn IX) and improved rotational period
(2020-02-01)
We report six stellar occultations by Phoebe (Saturn IX), an irregular satellite of Saturn, obtained between mid-2017 and mid-2019. The 2017 July 6 event was the first stellar occultation by an irregular satellite ever ...
Update of the statements on biology and clinical impact of occult hepatitis B virus infection
In October 2018 a large number of international experts with complementary expertise came together in Taormina to participate in a workshop on occult hepatitis B virus infection (OBI). The objectives of the workshop were ...
Inverting ionospheric radio occultation measurements using maximum entropy
(American Geophysical Union, 2007-08-18)
Practical aspects of the inversion of ionospheric radio occultation data using the Abel transform and its inverse are discussed. The linear inverse transform exhibits poor error propagation characteristics, producing ...
Apoptosis in tongue squamous cell carcinoma and its correlation with clinically occult cervical metastasis
(Pergamon-Elsevier B.V. Ltd, 2008-10-01)
Squamous cell carcinoma of the tongue is one of the most common head and neck cancer. Treatment in the early stages is still controversial. This study aims to correlate the apoptosis rate of primary tongue cancer with ...

Occult gastrointestinal bleeding is a common finding in dogs with chronic kidney disease
(2017-03-01)
Background: The risk of occult gastrointestinal bleeding (OGIB) is known to be increased among human dialysis patients suffering from end-stage renal disease. However, there are no studies to date that investigate the ...
SORA: Stellar occultation reduction and analysis
(Oxford Univ Press, 2022-02-04)
The stellar occultation technique provides competitive accuracy in determining the sizes, shapes, astrometry, etc., of the occulting body, comparable to in-situ observations by spacecraft. With the increase in the number ...
Pluto's ephemeris from ground-based stellar occultations (1988-2016)
(2019-01-01)
Context. From 1988 to 2016, several stellar occultations have been observed to characterise Pluto's atmosphere and its evolution. From each stellar occultation, an accurate astrometric position of Pluto at the observation ...
Occult hepatitis B and HIV infection
Introduction Occult hepatitis B virus (HBV) infection, so-called occult B infection (OBI), is defined by the recognition of HBV-DNA in the absence of serum hepatitis B surface antigen (HBsAg). The HBV-DNA genome in OBI is ...
First results from an airborne GPS radio occultation system for atmospheric profiling
(Amer Geophysical Union, 2014-03-16)
Global Positioning System (GPS) radio occultation (RO) from low Earth-orbiting satellites has increased the quantity of high-vertical resolution atmospheric profiles, especially over oceans, and has significantly improved ...
