Chemical compositions of stars in two stellar streams from the Galactic thick disk

, 2012
We present abundances for 20 elements for stars in two stellar streams identified by Arifyanto & Fuchs (2006, A&A, 449, 533): 18 stars from the Arcturus stream and 26 from a new stream, which we call AF06 stream, both from the Galactic thick disk ...

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires

Advanced Functional Materials, EarlyView.
In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

New meteor showers identified in the CAMS and SonotaCo meteoroid orbit surveys

, 2013
A cluster analysis was applied to the combined meteoroid orbit database derived from low-light level video observations by the SonotaCo consortium in Japan (64,650 meteors observed between 2007 and 2009) and by the Cameras for All-sky Meteor Surveillance

Chaotic Dispersal of Tidal Debris

, 2015
Several long, dynamically cold stellar streams have been observed around the Milky Way Galaxy, presumably formed from the tidal disruption of globular clusters.

MnI‐Functionalized Covalent Organic Framework as Efficient Electrocatalyst for CO2 Reduction in a Catholyte‐Free Zero‐Gap Electrolyzer

Advanced Functional Materials, EarlyView.
This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.

Kin discrimination in tadpoles of Hylarana temporalis (Anura: Ranidae) and Sphaerotheca breviceps (Anura: Dicroglossidae) hydroperiod and social habits

Phyllomedusa: Journal of Herpetology, 2014
Kin discrimination ability was studied in tadpoles of Hylarana temporalis and Sphaerotheca breviceps, which live in two distinctly different habitats; the former shows social aggregation and the latter live scattered. Early in development, tadpoles of H.
