The effect of orbital damping during planet migration on the Inclination and Eccentricity Distributions of Neptune Trojans [PDF]
, 2016 We explore planetary migration scenarios for formation of high inclination Neptune Trojans (NTs) and how they are affected by the planetary migration of Neptune and Uranus. If Neptune and Uranus's eccentricity and inclination were damped during planetary migration, then their eccentricities and inclinations were higher prior and during migration than ...

The Intrinsic Neptune Trojan Orbit Distribution: Implications for the Primordial Disk and Planet Migration [PDF]
, 2014 The present-day orbit distribution of the Neptune Trojans is a powerful probe of the dynamical environment of the outer solar system during the late stages of planet migration. In this work, I conservatively debias the inclination, eccentricity, and libration amplitude distributions of the Neptune Trojans by reducing a priori unknown discovery and ...

Pediatrics and Neonatology, 2016 Acute bronchiolitis is one of the main respiratory emergencies in young children. Although supportive therapy is recommended, substantial inconsistency in the clinical usage of inhaled treatments has been reported.

Neptune's wild days: constraints from the eccentricity distribution of the classical Kuiper Belt [PDF]
, 2012 Neptune's dynamical history shaped the current orbits of Kuiper belt objects (KBOs), leaving clues to the planet's orbital evolution. In the "classical" region, a population of dynamically "hot" high-inclination KBOs overlies a flat "cold" population with distinct physical properties.

Jumping Neptune Can Explain the Kuiper Belt Kernel [PDF]
, 2015 The Kuiper belt is a population of icy bodies beyond the orbit of Neptune. A particularly puzzling and up-to-now unexplained feature of the Kuiper belt is the so-called `kernel', a concentration of orbits with semimajor axes a~44 AU, eccentricities e~0.05, and inclinations i<5 deg.

Origin and Dynamical Evolution of Neptune Trojans - I: Formation and Planetary Migration [PDF]
Mon.Not.Roy.Astron.Soc.398: 1715-1729,2009, 2009 We present the results of detailed dynamical simulations of the effect of the migration of the four giant planets on both the transport of pre-formed Neptune Trojans, and the capture of new Trojans from a trans-Neptunian disk. We find that scenarios involving the slow migration of Neptune over a large distance (50Myr to migrate from 18.1AU to its ...

Meningitis from invasive Streptococcus agalactiae in a healthy young adult
IDCases, 2020 Streptococcus agalactiae is well known to be a potential etiology of bacterial meningitis in neonates. Invasive S. agalactiae has been also reported in nonpregnant adults.

Assessing the contribution of Centaur impacts to ice giant luminosities [PDF]
, 2015 Voyager 2 observations revealed that the internal luminosity of Neptune is an order of magnitude higher than that of Uranus. If the two planets have similar interior structures and cooling histories, the luminosity of Neptune can only be explained by invoking some energy source beyond gravitational contraction.

SAGE Open Medical Case Reports, 2023 Endoleaks are a common complication of endovascular aortic aneurysm repair and often lead to aneurysm rupture. We report a complex case of a Type IIIA endoleak in a patient with suspected cholangitis.

Compositional diversity in the atmospheres of hot Neptunes, with application to GJ 436b [PDF]
Astrophys. J., 777, 34 (2013), 2013 Neptune-sized extrasolar planets that orbit relatively close to their host stars -- often called "hot Neptunes" -- are common within the known population of exoplanets and planetary candidates. Similar to our own Uranus and Neptune, inefficient accretion of nebular gas is expected produce hot Neptunes whose masses are dominated by elements heavier than
