Direct detection and spectral characterization of extra-solar planets is one of the most exciting
but also one of the most challenging areas in modern astronomy. The challenge consists …

Observations of circumstellar environments that look for the direct signal of exoplanets and
the scattered light from disks have significant instrumental implications. In the past 15 years, …

We present the results of a search for dark matter weakly interacting massive particles (WIMPs)
in the mass range below 20 GeV/c 2 using a target of low-radioactivity argon with a …

Indicators are needed to assess environmental sustainability of bioenergy systems. Effective
indicators will help in the quantification of benefits and costs of bioenergy options and …

NIFS is a near-infrared integral field spectrograph designed for near diffraction-limited
imaging spectroscopy with the ALTAIR facility adaptive optics system on Gemini North. NIFS is …

Indicators are needed to assess both socioeconomic and environmental sustainability of
bioenergy systems. Effective indicators can help to identify and quantify the sustainability …

This article presents an experiment designed to test the reliability of the benefit function transfer
approach using contingent valuation methods. The experiment uses data collected from …

Background: It is uncertain if medical masks offer similar protection against COVID-19 compared
with N95 respirators. Objective: To determine whether medical masks are noninferior to …

Objective: The number of spectral channels is the number of discriminable pitches heard as
current is delivered to distinct locations along the cochlea. This study aimed to determine …

Landscape implications of bioenergy feedstock choices are significant and depend on land‐use
practices and their environmental impacts. Although land‐use changes and carbon …
