Tracking and Sketching Distributed Data Provenance
We describe a system for capturing data provenance in distributed applications, and the use of provenance sketches to optimize subsequent data provenance queries.

Captopril Increases the Intensity of Monocyte Infection By Trypanosoma Cruzi and Induces Human T Helper Type 17 Cells
Here we showed that captopril increases the intensity of T. cruzi infection of human monocytes in vitro. The increased parasitism was accompanied by up-regulated expression of ACE in human monocytes.

In Vivo MRSI of Hyperpolarized [1-13C]Pyruvate Metabolism in Rat Hepatocellular Carcinoma
We implemented a three-dimensional MRSI sequence to investigate this potential hallmark of cellular metabolism in rat livers bearing HCC (n = 7 buffalo rats).
-
An Application Framework for Loosely Coupled Networked Cyber-Physical Systems
We describe a new paradigm for programming an NCPS that enables users to specify their needs and nodes to contribute capabilities and resources.

Implementing SRI’s Pashto speech-to-speech translation system on a smartphone
We describe our recent effort implementing SRI's UMPC-based Pashto speech-to-speech (S2S) translation system on a smart phone running the Android operating system.

California’s Teaching Force 2010: Key Issues and Trends
This report covers four key themes: the contraction of the teacher workforce and other issues affecting the teacher supply pipeline, the weakening of the teacher development system in the context…

Fiber Tracking Functionally Distinct Components of the Internal Capsule
To examine the microstructural condition of this fiber system and to test functional correlates of its sectors in health and aging, adults were examined with diffusion tensor imaging fiber tracking…

Scientific foundations: a case for technology-mediated social-participation theory
Technology-mediated social-participation systems, such as Wikipedia and TopCoder, allow a vast user base to collaborate to solve difficult problems.
-
An elaborated model of social search
Our main contribution is that we have integrated models from previous work in sensemaking and information seeking behavior to present a canonical social model of user activities before, during, and…
-
Advancing the design of technology-mediated social participation systems
Using research from several fields, we can learn how to design better TMSP systems and to better integrate lessons learned in practice back into theory.

Spatially modulated emission advances point-of-care diagnostics
We have demonstrated, prototyped, and benchmarked against commercial systems a new optical detection approach that delivers high signal-to-noise discrimination without complex optics or bulky excitation sources.
