On the minimum side information of MIMO broadcast channel
We introduce a technique to achieve dirty paper coding (DPC) capacity asymptotically with minimum feedback required reported to date in literature.

Sensemaking with tweeting: exploiting microblogging for knowledge workers
In this paper, we discuss a number of ways to exploit microblogging in support of two recurrent sensemaking tasks: (1) when a user is seeking information (information foraging and active exploration) and (2) when information is delivered to the user (awareness and passive monitoring).

A torrent of tweets: managing information overload in online social streams
We propose that the research community engage with microblogging feed consumption practice: how do users manage the incoming flood of updates, and how can we help them do it?

Recombination in organic solar cells
The talk will discuss the transport and recombination processes in BJH cells, based on measurements made on polycarbazole/fullerene blend solar cells which have efficiency of about 5%.

All ink-jet printed polyfluorene photodiode for high illuminance applications
We have been developing a monitoring system that could be worn by soldiers to collect daily information that can be used as part of their medical record.

Handheld flow cytometer for monitoring bacteria in water
In order to achieve more timely assessment of water quality, we have developed and tested a hand-held, opto-fluidic-chip-based flow cytometer that promises to meet the requirements for point-of-need microbiological testing of water.

Compact and fast optical vibration sensor
Optical sensors offer many distinct advantages in comparison to their electronic counterparts: high sensitivity, remote and distributed sensing, use in harsh environments, and immune to electromagnetic interference.

Comparison of Indoor Robot Localization Techniques in the Absence of GPS
We report here on the performance of several implementations of the main class of localization algorithms that use a laser, Simultaneous Localization And Mapping (SLAM) on the RAWSEEDS benchmark.

Designing the Logistics for Large-Scale Randomized Controlled Trials: Six Strategies for Implementation at Scale
The Scaling Up SimCalc Project demonstrates how careful attention to logistics can permit use of a distributed data strategy in a set of large-scale experiments without compromising rigorous control and systematic organization of data.

Metabolic Imaging in the Anesthetized Rat Brain Using Hyperpolarized [1-(13)C] Pyruvate and [1-(13)C] Ethyl Pyruvate
In this initial study, we explore the feasibility of polarizing a stable formulation of [1-13C]-EP and compare spectroscopic images of uptake and metabolism in normal anesthetized rat brain relative to the uptake and metabolism of hyperpolarized [1-13C]-pyruvate.

Space-Based Constraints on Spatial and Temporal Patterns of NOx Emissions in California, 2005-2008
We describe ground and space-based measurements of spatial and temporal variation of NO2 in four California metropolitan regions.
