Spectroscopy along Multiple, Lensed Sightlines through Outflowing Winds in the Quasar SDSS J1029+2623 [PDF]
, 2012 We study the origin of absorption features on the blue side of the C IV broad emission line of the large-separation lensed quasar SDSS J1029+2623 at z_em ~ 2.197.

Journal of Neurochemistry, Volume 170, Issue 4, April 2026.Restraint stress triggers anxiety, along with a loss of polarization and coverage of aquaporin‐4 (AQP4) in astrocytes of the frontal cortex; these effects are attenuated by blockade of adenosine A2A receptors. ABSTRACT Repeated stress triggers anxiety accompanied by a deregulation of cortical glucocorticoid receptors, which is relieved by blocking ...

Surveying the Onset and Evolution of Supermassive Black Holes at High-z with AXIS
UniverseThe nature and origin of supermassive black holes (SMBHs) remain an open matter of debate within the scientific community. While various theoretical scenarios have been proposed, each with specific observational signatures, the lack of sufficiently ...

Work in Progress: Use of Wood‐Based Inserts in Injection Molding
Engineering Reports, Volume 8, Issue 3, March 2026.The study investigates the suitability of wood‐based mold inserts for the production of small series in polymer injection molding, showing that specially modified materials like laminated beech and compressed bamboo are more promising than natural woods. The results indicate that reproducible components can be produced with these tools. ABSTRACT In the

Anisotropy Analysis of Bamboo and Tooth Using 4‐Angle Polarization Micro‐Spectroscopy
Nano Select, Volume 7, Issue 3, March 2026.Super‐resolution via orientation: spatial distribution of specific molecular vibrations are revealed at 1/20 of the diffraction limit. ABSTRACT To investigate the anisotropic properties of biomaterials, two distinct classes are considered as follows: polymer‐based (cellulose in plants) and crystalline‐based (enamel in teeth), each demonstrating ...

Probing the faint end of the quasar luminosity function at z ~ 4 in the COSMOS field [PDF]
, 2010 We searched for quasars that are ~ 3 mag fainter than the SDSS quasars in the redshift range 3.7 < z < 4.7 in the COSMOS field to constrain the faint end of the quasar luminosity function.
