The Anatomical Record, EarlyView.Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

On the radius of habitable planets [PDF]
Astronomy & Astrophysics, 2013 Context. The conditions that a planet must fulfill to be habitable are not precisely known. However, it is comparatively easier to define conditions under which a planet is very likely not habitable. Finding such conditions is important as it can help select, in an ensemble of potentially observable planets, which ones should be observed in greater ...

Kepler-62:a five-planet system with planets of 1.4 and 1.6 Earth radii in the habitable zone
, 2013 We present the detection of five planets - Kepler-62b, c, d, e, and f - of size 1.31, 0.54, 1.95, 1.61 and 1.41 Earth radii (R⊕), orbiting a K2V star at periods of 5.7, 12.4, 18.2, 122.4, and 267.3 days, respectively.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny
The Anatomical Record, EarlyView.Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

An educated search for transiting habitable planets: (Research Note) Targetting M dwarfs with known transiting planets [PDF]
, 2010 Because the planets of a system form in a flattened disk, they are expected to share similar orbital inclinations at the end of their formation. The high-precision photometric monitoring of stars known to host a transiting planet could thus reveal the ...

Cardiac morphological and morphometric analysis of Ardea alba
The Anatomical Record, EarlyView.Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Arthritis &Rheumatology, EarlyView.Objective The aim of this study was to investigate whether exposure to mixture of individual fine particulate matter (PM2.5) chemical constituents is associated with incident systemic lupus erythematosus (SLE) and if ozone modifies this association and/or is associated with SLE onset.

Water Evolution and Inventories of Super-Earths Orbiting Late M Dwarfs
The Astrophysical JournalSuper-Earths orbiting M dwarf stars may be the most common habitable planets in the Universe. However, their habitability is threatened by intense irradiation from their host stars, which drives the escape of water to space and can lead to surface ...
