High Speed Optical Photometry of LMXBs and CVs [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractHigh speed photometry of several accreting binaries was obtained using the McDonald Observatory 2.1m telescope and ARGOS CCD photometer. A broad-band filter (BVR) was used in order to maximize flux and maintain a short (1-10s) integration time on faint targets.

Mitochondrial dysfunction: Related diseases, influencing factors, and detection

Interdisciplinary Medicine, EarlyView.
Mitochondrial dysfunction is implicated in the pathogenesis of numerous diseases, including neurological disorders, cancers, and cardiovascular conditions, through mechanisms such as mitochondrial DNA mutations, dysregulation of mitochondrial network dynamics, and impaired mitophagy.

Optical and Infrared Photometry of the Nearby Type Ia Supernovae 1999ee, 2000bh, 2000ca, and 2001ba [PDF]

, 2003
We present near infrared photometry of the Type Ia supernova 1999ee; also, optical and infrared photometry of the Type Ia SNe 2000bh, 2000ca, and 2001ba. For SNe 1999ee and 2000bh we present the first-ever SN photometry at 1.035 microns (the Y-band).

A Rapid In‐Field Soil Extraction Procedure to Measure Plant‐Available Soil P and K Using an ISFET Multi‐Sensor

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Knowledge of plant‐available soil nutrients is important for determining fertilizer requirements. Collecting this data rapidly and directly in the field could be beneficial for improving nutrient utilization efficiency. Aim Evaluation of the comparability of plant‐available soil phosphorus (Ppa) and potassium (Kpa) measurements with

New Optical/UV Counterparts and the Spectral Energy Distributions of Nearby, Thermally Emitting, Isolated Neutron Stars [PDF]

, 2011
We present Hubble Space Telescope optical and ultraviolet photometry for five nearby, thermally emitting neutron stars. With these measurements, all seven such objects have confirmed optical and ultraviolet counterparts. Combining our data with archival space-based photometry, we present spectral energy distributions for all sources and measure the ...

Lucky Imaging Adaptive Optics of the brown dwarf binary GJ569Bab

, 2011
The potential of combining Adaptive Optics (AO) and Lucky Imaging (LI) to achieve high precision astrometry and differential photometry in the optical is investigated by conducting observations of the close 0\farcs1 brown dwarf binary GJ569Bab.

Near-Infrared photometry of carbon stars in the Sagittarius dwarf irregular galaxy and DDO 210 [PDF]

, 2007
We investigate the intermediate-age asymptotic giant branch stellar population of two Local Group dwarf irregular galaxies to characterize their carbon star population in near-infrared (IR). Our work is based on J and K-band SOFI near-IR photometry complemented with optical ground based and HST photometry.

Optical and Near‐Infrared Photometry of Distant Galaxy Clusters

The Astrophysical Journal Supplement Series, 2002
We present optical and near-infrared photometry of 45 clusters of galaxies at 0.1 < z < 1.3. Galaxy catalogs in each cluster were defined at the longest wavelenth available, generally the K-band, down to approximately two magnitudes below M*. We include finding chart images of the band used for catalog definition.
