    • User-assisted intrinsic images 

      Bousseau, Adrien; Paris, Sylvain; Durand, Fredo (Association for Computing Machinery, 2009-12)
      For many computational photography applications, the lighting and materials in the scene are critical pieces of information. We seek to obtain intrinsic images, which decompose a photo into the product of an illumination ...

      Data quality is a critical problem in modern databases. Data entry forms present the first and arguably best opportunity for detecting and mitigating errors, but there has been little research into automatic methods for ...
    • Using 1-jettiness to measure 2 jets in DIS 3 ways 

      Kang, Daekyoung; Lee, Christopher; Stewart, Iain (American Physical Society, 2013-09)
      We predict cross sections in deep inelastic scattering (DIS) for the production of two jets—one along the proton beam direction created by initial-state radiation (ISR) and another created by final-state radiation after ...

      Sperm whales in the New England continental shelf and slope were passively localized, in both range and bearing, and classified using a single low-frequency (<2500 Hz), densely sampled, towed horizontal coherent hydrophone ...
    • Using a structural and logics systems approach to infer bHLH–DNA binding specificity determinants 

      Masi, Federico De; Grove, Christian A.; Vedenko, Anastasia; Alibes, Andreu; Gisselbrecht, Stephen S.; e.a. (Oxford University Press (OUP), 2011-02)
      Numerous efforts are underway to determine gene regulatory networks that describe physical relationships between transcription factors (TFs) and their target DNA sequences. Members of paralogous TF families typically ...
    • Using ACIS on the Chandra X-ray Observatory as a particle radiation monitor 

      Grant, Catherine E.; La Marr, Beverly J.; Bautz, Marshall W.; O'Dell, S. L. (SPIE, 2010-07)
      The Advanced CCD Imaging Spectrometer (ACIS) is one of two focal-plane instruments on the Chandra X-ray Observatory. During initial radiation-belt passes, the exposed ACIS suffered significant radiation damage from trapped ...
    • Using action research to improve learning and formative assessment to conduct research 

      Etkina, Eugenia; Karelina, Anna; Murthy, Sahana; Ruibal-Villasenor, Maria (American Physical Society, 2009-06)
      The paper reports on how educational research informed and supported both the process of refinement of introductory physics laboratory instruction and student development of scientific abilities. In particular we focus on ...
    • Using Ambulatory Voice Monitoring to Investigate Common Voice Disorders: Research Update 

      Mehta, Daryush D.; Van Stan, Jarrad H.; Ghassemi, Marzyeh; Guttag, John V.; Cheyne, Harold A.; e.a. (Frontiers Research Foundation, 2015-10)
      Many common voice disorders are chronic or recurring conditions that are likely to result from inefficient and/or abusive patterns of vocal behavior, referred to as vocal hyperfunction. The clinical management of hyperfunctional ...
    • Using an adaptive expertise lens to understand the quality of teachers’ classroom implementation of computer-supported reform curricula in high school science 

      Yoon, Susan A.; Koehler-Yom, Jessica; Anderson, Emma; Lin, Joyce; Klopfer, Eric (Taylor & Francis, 2015-04)
      Background: This exploratory study is part of a larger-scale research project aimed at building theoretical and practical knowledge of complex systems in students and teachers with the goal of improving high school biology ...
    • Using an atlas of gene regulation across 44 human tissues to inform complex disease- and trait-associated variation
