Light-induced coleoptile stimulation and mesocotyl suppression in etiolated Avena sativa (cv. Lodi) has been quantitated. Etiolated seedlings showed the greatest response to light when they were illuminated 48 to 56 hours after imbibition. Two low-irradiance photoresponses for each tissue have been described. Red light was 10 times more effective than green and 1,000 times more effective than f...

BACKGROUND Episodes of Emergency Department (ED) service use among older adults previously have not been constructed, or evaluated as multi-dimensional phenomena. In this study, we constructed episodes of ED service use among a cohort of older adults over a 15-year observation period, measured the episodes by severity and intensity, and compared these measures in predicting subsequent hospitali...

The WARRP router implements progressive deadlock recovery-based true-fully-adaptive routing in an efficient architecture designed to maximize flexibility as well as speed. The WARRP II version addresses the I/O pin-out problem by integrating dense high-bandwidth optoelectronic transceivers onto the router chip capable of providing over 300 GBytes/sec per square centimeter [7]. To our knowledge,...

We present measurements of the spatial response of infrared dipole and bow-tie lithographic antennas. Focused 10.6-microm radiation was scanned in two dimensions across the receiving area of each antenna. Deconvolution of the beam profile allowed the spatial response to be measured. The in-plane width of the antenna's spatial response extends approximately one dielectric wavelength beyond the m...

BACKGROUND Varicella has an important impact on public health. Starting in 2004 in Taiwan, nationwide free varicella vaccinations were given to 1-year-old children. METHODS Our study investigated the epidemiological characteristics of varicella from 2000 to 2008, and assessed the change of varicella epidemiology after the mass varicella immunization. ICD-9-CM codes related to varicella or chi...

Administrative data from a Canadian province were accessed to assess the association of psychotic disorders with multiple sclerosis (MS). Physician-assigned ICD-9-CM codes were used to classify MS and psychotic disorder status. A significant association was observed. Additional research is needed to determine the clinical importance and treatment needs of this population.

A medium for the isolation and enumeration of Malassezia furfur is described. Incubation at 34 degrees C yielded geometric mean counts (in CFU per square centimeter) of 2.6 X 10(3) on the forehead, 8.5 X 10(2) on the cheek, and 9.6 X 10(3) on the back. These counts compared favorably with microscopic counts and greatly exceeded those obtained with previously described media.

Organ transplantation is an expensive, life-saving technology. Previous studies have found that few transplant recipients in the United States lack health insurance (in part because patients may become eligible for special coverage because of their disability and transplant teams vigorously advocate for their patients). Few data are available on the insurance status of U.S. organ donors. The au...

Tumor spheroids are increasingly recognized as an important in vitro model for the behavior of tumor cells in three dimensions. More physiologically relevant than conventional adherent-sheet cultures, they more accurately recapitulate the complexity and interactions present in real tumors. In order to harness this model to better assess tumor biology, or the efficacy of novel therapeutic agents...

We describe monocrystalline graphitic films, which are a few atoms thick but are nonetheless stable under ambient conditions, metallic, and of remarkably high quality. The films are found to be a two-dimensional semimetal with a tiny overlap between valence and conductance bands, and they exhibit a strong ambipolar electric field effect such that electrons and holes in concentrations up to 10(1...
