Large Scale Structure in Dark Matter and Galaxies [PDF]

, 2009
Galaxy evolution and AGN growth in the early universe are believed to be strongly driven by merging (hierarchical growth) and galaxy dynamical interactions.

Copper Stress Response of Antibiotic‐Resistant and Copper‐Tolerant Enterococcus faecium and the Antibacterial Efficacy of Functionalized Copper Surfaces

Advanced Materials Interfaces, EarlyView.
This study examines how different laser‐patterned copper and brass surfaces, including copper coatings, affect the survival of vancomycin‐resistant Enterococcus faecium. Using microscopy and genome analysis, the results show that copper tolerance varies between strains and can increase after vancomycin exposure.

When is a Bulge Not a Bulge? Revealing the Satellite Nature of NGC 5474’s Bulge

The Astrophysical Journal
A satellite galaxy of the nearby spiral M101, NGC 5474 has a prominent bulge offset from the kinematic center of the underlying star-forming disk that has gained attention in recent years.

Quantified HI Morphology I: Multi-Wavelengths Analysis of the THINGS Galaxies [PDF]

, 2011
Galaxy evolution is driven to a large extent by interactions and mergers with other galaxies and the gas in galaxies is extremely sensitive to the interactions. One method to measure such interactions uses the quantified morphology of galaxy images. Well-

Dynamic Chiral Plasmonic Systems‐Based on Spiropyran Derivatives and Gold Nanorods

Advanced Materials Interfaces, EarlyView.
Soft chiral plasmonic nanocomposites are prepared by embedding gold nanorods into spiropyran‐based supramolecular gels. The system self‐assembles into helical structures, enabling plasmonic circular dichroism. When illuminated with UV light spiropyran–merocyanine isomerization occurs, inducing reversible nanoscale reorganization and modulation of the ...

A Proof‐of‐Concept Assessment of a Novel Wearable Eyelid Muscle Device: A Pre‐Clinical Animal Cadaver Study for Eyelid Closure Restoration

Advanced Robotics Research, EarlyView.
This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Merging Gas-rich Galaxies That Harbor Low-luminosity Twin Quasars at z = 6.05: A Promising Progenitor of the Most Luminous Quasars

The Astrophysical Journal
We present Atacama Large Millimeter/submillimeter Array [C ii ] 158 μ m line and underlying far-IR continuum emission observations (0.″57 × 0.″46 resolution) toward a quasar–quasar pair system recently discovered at z = 6.05. The quasar nuclei (C1 and C2)

Collisional interaction limits between dark matters and baryons in `cooling flow' clusters

, 2007
Presuming weak collisional interactions to exchange the kinetic energy between dark matter and baryonic matter in a galaxy cluster, we re-examine the effectiveness of this process in several `cooling flow' galaxy clusters using available X-ray ...
