Are Passive Spiral Galaxies Truly “Passive” and “Spiral”? : Near-Infrared Perspective

Passive spiral galaxies — unusual galaxies with spiral morphology without any sign of ongoing star formation — have recently been discovered to exist preferentially in cluster infalling regions (at about the virial radius, or at a local galaxy density of ∼ 1 Mpc). The discovery directly connects the passive spiral galaxies to the cluster galaxy evolution studies such as the Butcher-Oemler effec...

Herschel⋆-ATLAS/GAMA: Dusty early-type galaxies and passive spirals

We present the dust properties and star-formation histories of local submillimetreselected galaxies, classified by optical morphology. Most of the galaxies are late types and very few are early types. The early-type galaxies that are detected contain as much dust as typical spirals, and form a unique sample that has been blindly selected at submillimetre wavelengths. Additionally, we investigat...

From Passive Dynamic Walking to Passive Turning of Biped walker

Dynamically stable biped robots mimicking human locomotion have received significant attention over the last few decades. Formerly, the existence of stable periodic gaits for straight walking of passive biped walkers was well known and investigated as the notion of passive dynamic walking. This study is aimed to elaborate this notion in the case of three dimensional (3D) walking and extend it f...

Large arteries are more than passive conduits.

Passive blood anaphylaxis: subcutaneous immunoglobulins are a cause of ongoing passive anaphylactic reaction

BACKGROUND Allergic, especially anaphylactic, reactions during immunoglobulin replacement therapy are rare, but their pathophysiology and classification remain ambiguous. Recent findings show positive results of skin tests with commercially available immunoglobulins, but target antigens and responsible compounds of the tested immunoglobulins have not been strictly identified.
