Evaluating Multimedia Features and Fusion for Example-Based Event Detection
To study the value of multimedia features and fusion for representing and learning events from a set of example video clips, we created SESAME, a system for video SEarch with Speed and Accuracy for Multimedia Events.

Non-Invasive Recognition of Poorly Resolved Integrated Circuit Elements
We present a non-invasive method for recognition of components in a digital CMOS integrated circuit (IC). We use a confocal infrared laser scanning optical microscope to collect multimodal images through the backside of the IC.

Horizontal Parameters of Daytime Thermospheric Gravity Waves and E Region Neutral Winds over Puerto Rico
We report on the electron density perturbation amplitudes, periods (up to 60 min), horizontal and vertical wavelengths, phase speeds, and propagation directions of daytime traveling ionospheric disturbances (TIDs) from 115 to 300 km altitude using dual-beam experiments at the Arecibo Observatory (AO), Puerto Rico.

The Hypocretin/Orexin Antagonist Almorexant Promotes Sleep without Impairment of Performance in Rats
To test the hypothesis that less functional impairment results from HcrtR antagonist-induced sleep, we evaluated the performance of rats in the Morris Water Maze in the presence of ALM vs. ZOL.

Comparative Molecular Field Analysis of Fenoterol Derivatives Interacting with an Agonist-Stabilized Form of the β(2)-Adrenergic Receptor
The β2-adrenergic receptor (β2-AR) agonist [3H]-(R,R′)-methoxyfenoterol was employed as the marker ligand in displacement studies measuring the binding affinities (Ki values) of the stereoisomers of a series of 4′-methoxyfenoterol analogs in which the length of the alkyl substituent at α′ position was varied from 0 to 3 carbon atoms.

Young Youth Explore Geospatial Data for Citizenship Project: A case study
Whether in formal or informal science youths’ engagement with data, particularly raw data, is threatened when supports are insufficient for drawing meaning from the data. For example, there may be insufficient explanation of how the data are structured and how to make sense of the statistics that are displayed as forms of data reduction (e.g.,…

Flow cytometry on a chip
After a brief review of some new technologies important for on the flow anayte characterization we will describe an optical detection technique termed spatially modulated fluorescence emission developed at PARC which can delivers high signal-to-noise discrimination without precision optics to enable a flow cytometer that can combine high performance, robustness, compactness, low cost, and ease…
