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 ...

A Massive Quiescent Galaxy in a Group Environment at z = 4.53

The Astrophysical Journal
We report on the spectroscopic confirmation of a massive quiescent galaxy at z _spec = 4.53 in the COSMOS field. The object was first identified as a galaxy with suppressed star formation at z _phot ∼ 4.65 from the COSMOS2020 catalog.

The Identification of a Dusty Multiarm Spiral Galaxy at z = 3.06 with JWST and ALMA

The Astrophysical Journal Letters, 2022
Spiral arms serve crucial purposes in star formation and galaxy evolution. In this paper, we report the identification of “A2744-DSG- z 3,” a dusty, multiarm spiral galaxy at z = 3.059 using the James Webb Space Telescope (JWST) NIRISS imaging and grism ...

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 ...

Baryonically Closed Galaxy Groups

The Astrophysical Journal, 2005
Elliptical galaxies and their groups having the largest L_x/L_B lie close to the locus in the L_x,L_B diagram expected for closed systems with baryon fractions equal to the cosmic mean value, f_b = 0.16. The estimated baryon fractions for several of these galaxies/groups are also close to 0.16 when the gas density is extrapolated to the virial radius ...

Isolated Galaxies, Pairs and Groups of Galaxies [PDF]

International Astronomical Union Colloquium, 1990
We searched for isolated galaxies, pairs and groups of galaxies in the CfA survey (Huchra et al. 1983). It was assumed that the distances to galaxies are given by R = V/H0, where H0 = 100 km s−1 Mpc−1 and R> 6 Mpc.

Galaxy Assembly Bias in the Stellar-to-halo Mass Relation for Red Central Galaxies from SDSS

The Astrophysical Journal
We report evidence of galaxy assembly bias—the correlation between galaxy properties and biased secondary halo properties at fixed halo mass ( M _H )—in the stellar-to-halo mass relation for red central galaxies from the Sloan Digital Sky Survey.

Optical Observations of M81 Galaxy Group in Narrow Band [SII] and H_alpha Filters: Holmberg IX [PDF]

Serbian Astronomical Journal, 2009
We present observations of the nearby tidal dwarf galaxy Holmberg IX in M81 galaxy group in narrow band [SII] and H$alpha$ filters, carried out in March and November 2008 with the 2m RCC telescope at NAO Rozhen, Bulgaria.
