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…

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…

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.

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.

MR Diffusion Tensor Imaging: a Window Into White Matter Integrity of the Working Brain
Here we present an overview of the principles of diffusion tensor imaging (DTI) and its contribution to progress in our current understanding of normal and pathological brain function.

On Large-Scale Wave Structure and Equatorial Spread F Without a Post-Sunset Rise of the F Layer
Large-scale wave structure (LSWS) and the plasma structure, referred to as equatorial spread F (ESF), are shown, for the first time, to develop on a night, when the post-sunset rise (PSSR) of…
