AXIS: Generating Explanations at Scale with Learnersourcing and Machine Learning
(2016)While explanations may help people learn by providing information about why an answer is correct, many problems on online platforms lack high-quality explanations. This paper presents AXIS (Adaptive eXplanation Improvement ... -
The Balance‐Sample Size Frontier in Matching Methods for Causal Inference
(Wiley, 2016-11-09)We propose a simplified approach to matching for causal inference that simultaneously optimizes both balance (between the treated and control groups) and matched sample size. This procedure resolves two widespread tensions ... -
Band alignment of SnS/Zn(O,S) heterojunctions in SnS thin film solar cells
(American Institute of Physics, 2013)Band alignment is critical to the performance of heterojunction thin film solar cells. In this letter, we report band alignment studies of SnS/Zn(O,S) heterojunctions with various compositions of Zn(O,S). Valence band ... -
The Big and the Small: Challenges of Imaging the Brain's Circuits
(American Association for the Advancement of Science (AAAS), 2011)The relation between the structure of the nervous system and its function is more poorly understood than the relation between structure and function in any other organ system. We explore why bridging the structure-function ... -
Biologically-Inspired Control for Multi-Agent Self-Adaptive Tasks
(American Association for Artificial Intelligence (AAAI) Press, 2010)Decentralized agent groups typically require complex mechanisms to accomplish coordinated tasks. In contrast, biological systems can achieve intelligent group behaviors with each agent performing simple sensing and actions. ... -
Bound States of Guided Matter Waves: An Atom and a Charged Wire
(American Physical Society, 1992)We argue that it is possible to bind a neutral atom in stable orbits around a wire charged by a time-varying sinusoidal voltage. Both classical and quantum-mechanical theories for this system are discussed, and a unified ... -
Bridging cultural sociology and cognitive psychology in three contemporary research programmes
(Springer Nature, 2017)Three prominent research programs in cognitive psychology would benefit from a stronger engagement with the cultural context of cognition: studies of poverty focused on scarcity and cognitive bandwidth (CB); of the ... -
Bringing Operational GIS into University Classrooms
(2009)This study explores an innovative approach in teaching operational GIS to students who have taken only one introductory GIS course. It brings real world cases into university classrooms and exposes students to practical ... -
Burying the Beloved: Marriage, Realism, and Reform in Modern Iran

Calibrating abundance indices with population size estimators of red back salamanders (Plethodon cinereus) in a New England Forest.
(PeerJ Inc., 2015)Herpetologists and conservation biologists frequently use convenient and cost-effective, but less accurate, abundance indices (e.g., number of individuals collected under artificial cover boards or during natural objects ... -
Cancer metastasis networks and the prediction of progression patterns
(Nature Publishing Group, 2009) -
Canopy and Litter Ant Assemblages Share Similar Climate-Species Density Relations
(Royal Society, 2010)Tropical forest canopies house most of the globe’s diversity, yet little is known about global patterns and drivers of canopy diversity. Here we present models of ant species density, using climate, abundance and habitat ... -
Children’s Books, Dolls, and the Performance of Race; or, The Possibility of Children’s Literature
(The Modern Language Association of America, 2011) -
Coherence of Nitrogen-Vacancy Electronic Spin Ensembles in Diamond
(American Physical Society, 2010)We present an experimental and theoretical study of electronic spin decoherence in ensembles of nitrogen-vacancy (NV) color centers in bulk high-purity diamond at room temperature. Under appropriate conditions, we find ... -
Collapse and Folding of Pressurized Rings in Two Dimensions
(American Physical Society, 2009)Hydrostatically pressurized circular rings confined to two dimensions (or cylinders constrained to have only z-independent deformations) undergo Euler-type buckling when the outside pressure exceeds a critical value. We ... -
Collective Decision-Making in Multi-Agent Systems by Implicit Leadership
(Association for Computing Machinery Press, 2010)Coordination within decentralized agent groups frequently requires reaching global consensus, but typical hierarchical approaches to reaching such decisions can be complex, slow, and not fault-tolerant. By contrast, recent ... -
Comment on "Sensitivity of Seafloor Bathymetry to Climate-Driven Fluctuations in Mid-Ocean Ridge Magma Supply"
(American Association for the Advancement of Science (AAAS), 2016)Recent studies have proposed that the bathymetric fabric of the seafloor formed at mid-ocean ridges records rapid (23,000 to 100,000 years) fluctuations in ridge magma supply caused by sealevel changes that modulate melt ... -
Comparative effectiveness of generic versus brand-name antiepileptic medications
(Elsevier BV, 2015)OBJECTIVE: The objective of this study was to compare treatment persistence and rates of seizure-related events in patients who initiate antiepileptic drug (AED) therapy with a generic versus a brand-name product. METHODS: ... -
Comparative Lesion Sequencing Provides Insights into Tumor Evolution
(Proceedings of the National Academy of Sciences, 2008)We show that the times separating the birth of benign, invasive, and metastatic tumor cells can be determined by analysis of the mutations they have in common. When combined with prior clinical observations, these analyses ... -
Complexity: An energetics agenda
