Unbiased discourse segmentation evaluation
We show that the performance measures Pk and Window Diff, commonly used for discourse, topic, and story segmentation evaluation, are biased in favor of segmentations with fewer or adjacent segment…

Gravity Wave Activity in the Arctic Stratosphere and Mesosphere During the 2007-2008 and 2008-2009 Stratospheric Sudden Warming Events
We report Rayleigh lidar measurements of nightly temperature profiles in the 40–80 km altitude region and 30 min relative density profiles in the 40–50 km altitude region at Chatanika, Alaska…

Neurocircuitry of Emotion and Cognition in Alcoholism: Contributions from White Matter Fiber Tractography
An understanding of the role of cortico-limbic fiber degradation in emotional dysregulation in alcoholism is now emerging.

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.

Solution-processed, inkjet-patterned non-volatile memory arrays
Inkjet printing was used to pattern ferroelectric field effect transistors (feFETs) and addressing thin film transistors (TFTs).

NPI licensing in temporal clauses
This paper offers a systematic approach to NPI licensing in temporal clauses based on a uniform analysis of temporal connectives as relations between times and relying on appropriate type shifting…

Do your friends make you smarter?: an analysis of social strategies in online information seeking
Our goal in this paper is to document the methods and outcomes of using social resources to help with exploratory search tasks.

Soft matter, biological materials and biomedical materials synthesis, characterization and applications
These symposia explore a common theme of how biological and soft material properties may be harnessed to build new structural features or elicit useful structural responses, either to understand the…
