We report the discovery of 12 new satellites of Jupiter, giving Jupiter 79 known satellites. The new finds are between 23rd-24th mag in the r-band and 1-3 km in diameter assuming dark albedos. Nine of the discoveries are in the distant retrograde sat

We studied the Near-Earth Asteroid (NEA) candidates posted on the Minor Planet Center's Near-Earth Object Confirmation Page (NEOCP) between years 2013 and 2016. Out of more than 17,000 NEA candidates, while the majority became either new discoveries

We describe the digest2 software package, a fast, short-arc orbit classifier for small Solar System bodies. The digest2 algorithm has been serving the community for more than 13 years. The code provides a score, D2, which represents a pseudo-probabil

For absolute magnitudes greater than the current completeness limit of H-magnitude ∼15 the main asteroid belt's size distribution is imperfectly known. We have acquired good-quality orbital and absolute H-magnitude determinations for a sample of sm

Both Helicobacter pylori and pepsin are proven mucosal damaging agents and implicated in the aetiology of peptic ulcer disease. Historically studies of pepsin over time have proved methodologically difficult, and as a result little work has been done

Background: Peptic ulceration and Helicobacter pylori infection increase with advancing age. In the upper gastro-intestinal tract the first line of mucosal defence is the adherent mucus gel layer. Objective: We have examined, using a novel histologic

A total of 701 comets received names between July 2005 and June 2008. Comets observed only from the SOHO and STEREO missions, as well as further comets recognized from the long-defunct SOLWIND satellite, accounted for 520 of these names.

A cohort of patients with a histological diagnosis of colorectal carcinoma was enrolled prospectively. All subjects were interviewed by one observer using a structured questionnaire. One hundred and fifty 'young' (under 70 years) and 123 'elderly' (7
