A Revised Historical Light Curve of Eta Carinae and the Timing of Close Periastron Encounters

, 2010
The historical light curve of the 19th century "Great Eruption" of etaCar provides a striking record of violent instabilies encountered by the most massive stars.

Rapid laccolith intrusion driven by explosive volcanic eruption

Nature Communications, 2016
Magmatic intrusions and volcanic eruptions are intimately related phenomena. Shallow magma intrusion builds subsurface reservoirs that are drained by volcanic eruptions. Thus, the long-held view is that intrusions must precede and feed eruptions. Here we

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Eruptive syringomas

Dermatology Online Journal, 2005
Eruptive syringoma is a rare clinical presentation of a benign tumor of the eccrine ducts. It consists in successive crops of small skin-colored papules on the anterior body surfaces. It generally occurs in the peri-pubertal period. Treatment of this benign condition is cosmetic only.

The 1257 Samalas eruption (Lombok, Indonesia): the single greatest stratospheric gas release of the Common Era

Scientific Reports, 2016
Large explosive eruptions inject volcanic gases and fine ash to stratospheric altitudes, contributing to global cooling at the Earth’s surface and occasionally to ozone depletion.

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

The Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Relation of Birth Weight with Time of First Deciduous Tooth

Acta Medica Iranica, 2009
The deciduous teeth play a very important role in proper alignment, placing and occlusion of permanent teeth. Calcification of deciduous teeth begins during the fourth month of fetal life, and by the end of sixth month all of the deciduous teeth have ...

Volcanic plume measurements using a UAV for the 2014 Mt. Ontake eruption

Earth, Planets and Space, 2016
A phreatic eruption of Mt. Ontake, Japan, started abruptly on September 27, 2014, and caused the worst volcanic calamity in recent 70 years in Japan. We conducted volcanic plume surveys using an electric multirotor unmanned aerial vehicle to elucidate ...

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

The Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).
