The galaxy luminosity function in groups and clusters: the faint-end upturn and the connection to the field luminosity function [PDF]

open access: yes, 2015
We characterize the luminosity functions of galaxies residing in $z\sim0$ groups and clusters over the broadest ranges of luminosity and mass reachable by the Sloan Digital Sky Survey.

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Near-infrared luminosity function and colours of dwarf galaxies in the Coma Cluster [PDF]

open access: yes, 1997
We present K-band observations of the low-luminosity galaxies in the Coma cluster, which are responsible for the steep upturn in the optical luminosity function at M_R ~ -16, discovered recently.

The gamma-ray luminosity function of millisecond pulsars and implications for the GeV excess [PDF]

open access: yes, 2015
It has been proposed that a large population of unresolved millisecond pulsars (MSPs) could potentially account for the excess of GeV-scale gamma-rays observed from the region surrounding the Galactic Center.

Characteristics of Cerebral Palsy in the Midwestern US

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cerebral palsy (CP) is the most common lifelong motor disability worldwide. Yet, data is limited on how CP manifests in the US. Our objective was to characterize and determine factors affecting functional outcomes in a large population of young people with CP in the Midwestern US.

Luminosity Function of Galaxies in Voids: A Modification Inspired by Excursion Set Theory

open access: yesThe Astrophysical Journal
In the standard picture of cosmology, the galaxies reside in dark matter (DM) halos. DM halos are distributed in the cosmic web in different environments.

The Truncated Lindley Distribution with Applications in Astrophysics

open access: yesGalaxies, 2019
This paper reviews the Lindley distribution and then introduces the scale and the double truncation. The unknown parameters of the truncated Lindley distribution are evaluated with the maximum likelihood estimators.

The Origin of the Consistent Planetary Nebula Luminosity Function Bright-end Cutoff

open access: yesThe Astrophysical Journal, 2023
The [O iii ] 5007 Å line is typically the brightest line in planetary nebula (PN) spectra. Observations show that the brightest [O iii ] 5007 Å PN in a galaxy—the planetary nebula luminosity function (PNLF) bright-end cutoff—is surprisingly independent ...

Luminosity function of faint Galactic sources in the Chandra bulge field

open access: yes, 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 ...

Annual 12‐Week Dosing Gap of Natalizumab: Clinical Efficacy, Blood Biomarkers, and CSF Cell Composition

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Natalizumab (NTZ) is a highly effective therapy for multiple sclerosis (MS); however, its use is limited by the risk of a rare potentially severe opportunistic brain infection, progressive multifocal leukoencephalopathy (PML). Alternative dosing strategies are evaluated to reduce PML risk while still maintaining efficacy, which ...
