Static current-sheet models of quiescent prominences [PDF]

open access: yes
A particular class of theoretical models idealize the prominence to be a discrete flat electric-current sheet suspended vertically in a potential magnetic field. The weight of the prominence is supported by the Lorentz force in the current sheet.

Limits on the quiescent radio emission from the black hole binaries GRO J1655-40 and XTE J1550-564

open access: yes, 2010
We present the results of radio observations of the black hole binaries GRO J1655-40 and XTE J1550-564 in quiescence, with the upgraded Australia Telescope Compact Array. Neither system was detected.

Architecture of an All‐In‐One Microfluidic Platform for Accelerated Cancer Seeding, Enhanced Spheroid Formation, and Dynamic Drug Screening Trials

open access: yesAdvanced Materials Technologies, EarlyView.
An all‐in‐one microfluidic platform consists of two‐layered PDMS channels integrated with a hydrogel microwell array. This platform enables flow‐driven tumor cell capture, enhanced spheroid formation within the microwells, and advective drug testing. ABSTRACT Effective cancer drug screening requires platforms that replicate the physiological complexity

Quantifying Bursty Star Formation in Dwarf Galaxies

open access: yesThe Open Journal of Astrophysics
Dwarf galaxy star formation histories are theoretically expected to be bursty, potentially leaving distinct imprints on their chemical evolution. We propose that episodic starbursts with quiescent periods longer than ~100 Myr should lead to discontinuous

Apparatus ad method for quiescent containerless processing of high temperature metals and alloys in low gravity [PDF]

open access: yes, 1987
The electron bombardment furnace consists of two confinement grid sections which may be moved and separated from each other. Inside the bombardment furnace, a tungsten element is enclosed.

Further Constraints on Thermal Quiescent X-ray Emission from SAX J1808.4-3658

open access: yes, 2008
We observed SAX J1808.4-3658 (1808), the first accreting millisecond pulsar, in deep quiescence with XMM-Newton and (near-simultaneously) Gemini-South. The X-ray spectrum of 1808 is similar to that observed in quiescence in 2001 and 2006, describable by ...

Constraining the properties of neutron star crusts with the transient low-mass X-ray binary Aql X-1 [PDF]

open access: yes, 2015
Aql X-1 is a prolific transient neutron star low-mass X-ray binary that exhibits an accretion outburst approximately once every year. Whether the thermal X-rays detected in intervening quiescent episodes are the result of cooling of the neutron star or ...

A major radio outburst in III Zw 2 with an extremely inverted, millimeter-peaked spectrum

open access: yes, 1999
III Zw 2 is a spiral galaxy with an optical spectrum and faint extended radio structure typical of a Seyfert galaxy, but also with an extremely variable, blazar-like radio core.
