Association of Systemic Inflammation With Retinal Vascular Caliber in Patients With AIDS. [PDF]

, 2019
PurposeTo evaluate relationships among retinal vascular caliber and biomarkers of systemic inflammation in patients with AIDS.MethodsA total of 454 participants with AIDS had retinal vascular caliber (central retinal artery equivalent and central retinal

The Formation of Brown Dwarfs: Observations

, 2006
We review the current state of observational work on the formation of brown dwarfs, focusing on their initial mass function, velocity and spatial distributions at birth, multiplicity, accretion, and circumstellar disks.

Inner disk regions revealed by infrared interferometry

, 2007
I review the results obtained by long-baseline interferometry at infrared wavelengths on the innermost regions around young stars. These observations directly probe the location of the dust and gas in the disks.

A Disk Around the Planetary-Mass Companion GSC 06214-00210 b: Clues About the Formation of Gas Giants on Wide Orbits [PDF]

, 2011
We present Keck/OSIRIS 1.1-1.8 um adaptive optics integral field spectroscopy of the planetary-mass companion to GSC 06214-00210, a member of the ~5 Myr Upper Scorpius OB association. We infer a spectral type of L0+/-1, and our spectrum exhibits multiple

Lopsided dust rings in transition disks

, 2013
Context. Particle trapping in local or global pressure maxima in protoplanetary disks is one of the new paradigms in the theory of the first stages of planet formation. However, finding observational evidence for this effect is not easy.

UV excess measures of accretion onto young very low-mass stars and brown dwarfs [PDF]

, 2008
Low-resolution spectra from 3000-9000 AA of young low-mass stars and brown dwarfs were obtained with LRIS on Keck I. The excess UV and optical emission arising in the Balmer and Paschen continua yields mass accretion rates ranging from 2e-12 to 1e-8 Mo ...

Boosting the Therapeutic Potential of Extracellular Vesicles Derived From Mesenchymal Stem Cells via Advanced Preconditioning for Neurodegenerative Disorders

Stem Cells International
Acute and chronic neurodegenerative conditions (NDs) are major causes of disability and mortality worldwide. Acute NDs encompass conditions such as stroke, traumatic brain injury (TBI), and spinal cord injury (SCI). On the other hand, chronic NDs include

Impact of the initial disk mass function on the disk fraction

, 2015
The disk fraction, the percentage of stars with disks in a young cluster, is widely used to investigate the lifetime of the protoplanetary disk, which can impose an important constraint on the planet formation mechanism.

Recycling of RAP (Reclaimed Asphalt Pavement) as aggregate for structural concrete: experimental study on physical and mechanical properties

Discover Civil Engineering
The replacement of natural aggregate in concrete with artificial and/or recycled one has recently gained attention as meaningful strategy to reduce the environmental impact of structural concrete and promote circular economy principles.
