Artificial Intelligences: A Bridge Toward Diverse Intelligence and Humanity's Future
Advanced Intelligent Systems, EarlyView.Many discussions of artificial intelligence fail to address deeper questions being raised by advances in developmental biology, neuroscience, bioengineering, and philosophy of mind. Novel beings, including technologically and biologically augmented humans, engineered life forms, hybrots, and others, require tools of the emerging field of diverse ...

Populating a cluster of galaxies - I. Results at z=0 [PDF]
, 2000 ABSTRA C T We simulate the assembly of a massive rich cluster and the formation of its constituent galaxies in a flat, low-density universe. Our most accurate model follows the collapse, the star formation history and the orbital motion of all galaxies ...

MMT Extremely Metal Poor Galaxy Survey I. An Efficient Technique to Identify Metal Poor Galaxies
, 2007 We demonstrate a successful strategy for identifying extremely metal poor galaxies. Our preliminary survey of 24 candidates contains 10 metal poor galaxies of which 4 have 12+log(O/H)

Hot Stars, Young Stellar Populations and Dust with Swift/UVOT
UniverseIn this review, we highlight the contributions made by the Swift/UVOT instrument to the understanding of the ultraviolet (UV) attenuation and extinction properties of interstellar dust and provide insight into hot stars and young stellar populations. The

Emission Knots and Polarization Swings of Swinging Jets
Galaxies, 2016 Knots (emission features in jets of active galactic nuclei) often show non-ballistic dynamics and variable emission/polarization properties. We model these features as emission pattern propagating in a jet that carries a helical magnetic field and is ...

Parametric Design of Continuum Robots Using Interlocking Ball Joints
Advanced Intelligent Systems, EarlyView.Herein, a parametric design methodology is introduced for producing a wide variety of modular ball joint‐based continuum robots. It is demonstrate by designing a magnetically actuated continuum robot for cardiac ablations. The methodology is released as an open‐source computer‐assisted design extension that automatically designs continuum robots based ...

The Auriga Project: the properties and formation mechanisms of disc galaxies across cosmic time [PDF]
, 2016 We introduce a suite of 30 cosmological magneto-hydrodynamical zoom simulations of the formation of galaxies in isolated Milky Way mass dark haloes. These were carried out with the moving mesh code arepo, together with a comprehensive model for galaxy ...

Compact E+A Galaxies as a Progenitor of Massive Compact Quiescent
Galaxies at 0.2
, 2016 We search the Sloan Digital Sky Survey and the Baryon Oscillation Sky Survey to identify ~5500 massive compact quiescent galaxy candidates at 0 ...
