The Europa Imaging System (EIS) Investigation.

The Europa Imaging System (EIS) consists of a Narrow-Angle Camera (NAC) and a Wide-Angle Camera (WAC) that are designed to work together to address high-priority science objectives regarding Europa's geology, composition, and the nature of its ice shell. EIS accommodates variable geometry and illumination during rapid, low-altitude flybys with both framing and pushbroom imaging capability using rapid-readout, 8-megapixel (4k × 2k) detectors. Color observations are acquired using pushbroom imaging with up to six broadband filters.

Variations in color and reflectance on the surface of asteroid (101955) Bennu.

Visible-wavelength color and reflectance provide information about the geologic history of planetary surfaces. Here we present multispectral images (0.44 to 0.

Analysis of the Risks and Benefits of New Chemical Entities Approved by the US Food and Drug Administration (FDA) and Subsequently Withdrawn From the US Market.

Benefit-risk evaluations of drugs have been conducted since the introduction of modern regulatory systems more than 50 years ago. Such judgments are typically made on the basis of qualitative or semiquantitative approaches, often without the aid of quantitative assessment methods, the latter having often been applied asymmetrically to place emphasis on benefit more so than harm. In an effort to preliminarily evaluate the utility of lives lost or saved, or quality-adjusted life-years (QALY) lost and gained as a means of quantitatively assessing the potential benefits and risks of a new chemical entity, we focused our attention on the unique scenario in which a drug was initially approved based on one set of data, but later withdrawn from the market based on a second set of data.

On-demand driver vigilance enhancement without explicit drowsiness detection-Further analysis of the pilot study results.

Objective: A new active safety concept that engages the driver's psychosensory pain-processing mechanism to automatically trigger vigilance enhancement on-demand was proposed in Chang (2012). This concept is based on the hypothesis that a human's pain threshold will decline as he or she becomes drowsy, consequently triggering the vigilance enhancer. The objective of this pilot study was to develop methods to test this hypothesis, the results of which could lead to further refinement of the hypothesis and methods, with the ultimate goal of developing new active safety concepts that exploit the driver's endogenous psychosensory pain-processing mechanisms.
