Edges of Saturn’s rings are fractal [PDF]

SpringerPlus, 2015
The images recently sent by the Cassini spacecraft mission (on the NASA website http://saturn.jpl.nasa.gov/photos/halloffame/) show the complex and beautiful rings of Saturn. Over the past few decades, various conjectures were advanced that Saturn's rings are Cantor-like sets, although no convincing fractal analysis of actual images has ever appeared ...

The Composition of Saturn's Rings [PDF]

Icarus, 2002
Abstract A composite spectrum between 0.30 and 4.05 μm of Saturn's rings is analyzed using the Shkuratov scattering theory (Shkuratov et al. 1999, Icarus 137 , 235–246). Several types of surface and composition are discussed. We demonstrate that both the strong reddening over the interval 0.3–0.7 μm and the water ice absorption features are well ...

New Arabic Records From Cairo on Supernovae 1181 and 1006

Astronomische Nachrichten, EarlyView.
ABSTRACT The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000–5000 year), the unusual star IRAS00500+6713 with a surrounding nebula (Pa‐30) has an expansion age not inconsistent with a SN Iax explosion in ad 1181 under the assumption that neither acceleration nor ...

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Filling Voids: Cubic Carbodiimide Nitride Nitridometalates (Ba6Nx)2[MN4][CN2]6 of M = Zr, Hf, Nb, Ta, Mo, and W

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The crystal structures of (Ba6Nx)2[MN4][CN2]6 (left) and “ideal” 2 × 2 × 2 Perovskite (right) show similar linkage patterns despite differently shaped coordination polyhedra. Cubic carbodiimide nitride nitridometalates (Ba6Nx)2[MN4][CN2]6 of M = Zr, Hf, Nb, Ta, Mo, and W are synthesized by various high‐temperature reactions and their respective crystal

RioM‐1: A New Calcite Reference Material for U‐Pb LA‐ICP‐MS Geochronology

Geostandards and Geoanalytical Research, EarlyView.
Key Points RioM‐1 calcite was characterised for trace elements, U‐Pb geochronology, Sr and O isotopes using ID‐TIMS, LA‐ICP‐MS and SIMS. U‐Pb dates from ID‐TIMS and LA‐ICP‐MS across several independent laboratories returned identical results within uncertainty.

Plasma electrons above Saturn's main rings: CAPS observations [PDF]

, 2005
We present observations of thermal ( similar to 0.6 - 100eV) electrons observed near Saturn's main rings during Cassini's Saturn Orbit Insertion (SOI) on 1 July 2004. We find that the intensity of electrons is broadly anticorrelated with the ring optical

Disconsolate Suffering: Joe Sacco's Comics Journalism and the Ambivalence of Humanitarian Witnessing

The Journal of Popular Culture, EarlyView.
ABSTRACT Through a close reading of Joe Sacco's seminal work of graphic journalism, Palestine, this article argues that Sacco unsettles the consoling effects of mass media by disrupting dominant narratives of difference, otherness, and spectacularized violence.

Cassini observations of the thermal plasma in the vicinity of Saturn's main rings and the F and G rings [PDF]

, 2005
The ion mass spectrometer on Cassini detected enhanced ion flux near Saturn's main rings that is consistent with the presence of atomic and molecular oxygen ions in the thermal plasma.

Decisions Under Radical Uncertainty: The Role of Volitional Liminality in Radical Innovation

Journal of Product Innovation Management, EarlyView.
ABSTRACT Academic Summary Radical innovation management can be understood as an organizational practice that enacts distant futures, which are open‐ended and unknowable. Such radical innovation endeavors are thus characterized by radical uncertainty, where possible futures are not only quantitatively but qualitatively different from the present, and ...
