Explaining the Gamma Ray Burst Lag/Luminosity and Variability/Luminosity Relations [PDF]

arXiv, 2001
Two different luminosity indicators have been recently proposed for Gamma Ray Bursts that use the lag between light curve peaks with hard and soft photons as well as the variability ('spikiness') of the burst light curve. Schaefer, Deng, & Band have proven that both of these luminosity indicators are valid by finding a lag/variability relation for 112 ...

Comparing Optical and Near Infrared Luminosity Functions [PDF]

, 2001
The Sloan Digital Sky Survey [SDSS] has measured an optical luminosity function for galaxies in 5 bands, finding 1.5 to 2.1 times more luminosity density than previous work. This note compares the SDSS luminosity density to two recent determinations of the near infrared luminosity function based on 2MASS data, and finds that an extrapolation of the ...

Swift-BAT Survey of Galactic Sources: Catalog and Properties of the populations

, 2010
We study the populations of X-ray sources in the Milky Way in the 15-55 keV band using a deep survey with the BAT instrument aboard the Swift observatory. We present the logN-logS distributions of the various source types and we analyze their variability

Bone‐wise rigid registration of femur, tibia, and fibula for the tracking of temporal changes

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Multiple myeloma (MM) induces temporal alterations in bone structure, such as osteolytic bone lesions, which are challenging to identify through manual image interpretation. The large variation in radiologists' assessments, even at expert centers, further complicates diagnosis.

The Luminosity Function of M3

, 1999
We present a high precision, large sample luminosity function (LF) for the Galactic globular cluster M3. With a combination of ground based and Hubble Space Telescope data we cover the entire radial extent of the cluster.

Amygdala Neurodegeneration: A Key Driver of Visual Dysfunction in Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Visual disability in Parkinson's disease (PD) is not fully explained by retinal neurodegeneration. We aimed to delineate the brain substrate of visual dysfunction in PD and its association with retinal thickness. Methods Forty‐two PD patients and 29 controls underwent 3‐Tesla MRI, retinal spectral‐domain optical coherence tomography,

Artificial Receptor in Synthetic Cells Performs Transmembrane Activation of Proteolysis

Advanced Biology, EarlyView.
Transmembrane signaling is the hallmark of living cells and is among the highest challenges for the design of synthetic cells. Herein, an artificial receptor based on the chemistry of self‐immolative linkers is used to communicate information across the lipid bilayer, for transmembrane activation of enzymatic activity. Abstract The design of artificial,

Luminosity Measurement at COMPASS

, 2011
The measurement of absolutely normalized cross sections for high-energy scattering processes is an important reference for theoretical models. This paper discusses the first determination of the luminosity for data of the COMPASS experiment, which is the

Luminosity function of faint Galactic sources in the Chandra bulge field

, 2011
We study the statistical properties of faint X-ray sources detected in the Chandra Bulge Field. The unprecedented sensitivity of the Chandra observations allows us to probe the population of faint Galactic X-ray sources down to luminosities L(2-10 keV ...
