Nitride laser diodes with non-epitaxial cladding layers
We describe a new laser diode architecture in which the upper cladding layer is replaced with an evaporated or sputtered non-epitaxial material.

Conversion of methionine to homocysteic acid in heavily oxidized proteomics samples
We present evidence that in heavily oxidized protein samples, such as those produced by hydroxyl radical surface mapping, a major oxidation product of methionine is homocysteic acid.

Inkjet-printed, organic complementary circuits integrated with polymer mechanical sensors
Organic complementary circuits are demonstrated for integration with mechanical sensors to enable the fabrication of a sensor tape to detect mechanical impacts correlated to traumatic brain injury.

The web as a privacy lab
In this position paper we argue that the very ability of Web data to breach privacy demonstrates its value as a laboratory for the detection of privacy breaches before they…

Personalized privacy policies: challenges for data loss prevention
In our study, users were asked to evaluate various expressive file names for sensitivity; that it, they were asked to consider how broadly they were willing to share those filenames…

Continual on-line planning as decision-theoretic incremental heuristic search
This paper presents an approach to integrating planning and execution in time-sensitive environments

Hand-held flow cytometer for point of care CD4 testing
PARC has demonstrated a new optical detection technique termed spatially modulated emission that delivers high signal-to-noise discrimination without precision optics to enable a flow cytometer that can combine high performance,…
-
Microfluidic platform for point-of-need analyte diagnostics based on spatial modulation detection
To help sharpen the focus on alternative approaches, this presentation will describe an optical detection technique that delivers high effective sensitivity (i.e., high S/N) without complex optics or bulky, expensive…

Across-phone variability and diagonal term in joint factor analysis for speaker recognition
We investigate usefulness of across-phone variability for speaker recognition in a joint factor analysis (JFA) framework. We estimate the variability as across-phone covariance within a conversation side averaged over all…
-
A comparison of approaches for modeling prosodic features in speaker recognition
In this work, we study the two modeling techniques for the simpler set of features. We show that, for these features, a combination of JFA systems for different sequence lengths…

Design of Short Linear Peptides That Show Hydrogen Bonding Constraints in Water
Using a combination of an aromatic amino acid, a homoserine side chain, and a d-amino acid, a series of linear tetrapeptides were designed that adopt an “Hse turn” in water.

Design Pattern On Model Use In Interdependence Among Living Systems (Large-Scale Assessment Technical Report 13)
The report outlines the key elements of the design pattern, describes the design pattern development process, and illustrates with examples how the design pattern supports storyboard and item design for…
