      Karger, David R.; Oh, Sewoong; Shah, Devavrat (Institute for Operations Research and the Management Sciences (INFORMS), 2014-02)
      Crowdsourcing systems, in which numerous tasks are electronically distributed to numerous “information pieceworkers,” have emerged as an effective paradigm for human-powered solving of large-scale problems in domains such ...
    • Buffer-Gas Cooled Bose-Einstein Condensate 

      Ketterle, Wolfgang; Connolly, Colin B.; Doyle, John M.; Doret, S. Charles (American Physical Society, 2009-09)
      We report the creation of a Bose-Einstein condensate using buffer-gas cooling, the first realization of Bose-Einstein condensation using a broadly general method which relies neither on laser cooling nor unique atom-surface ...
    • Building a better boosted top tagger 

      Larkoski, Andrew; Moult, Ian James; Neill, Duff Austin (American Physical Society, 2015-02)
      Distinguishing hadronically decaying boosted top quarks from massive QCD jets is an important challenge at the Large Hadron Collider. In this paper we use the power-counting method to study jet substructure observables ...

    • Building a Freshman-Year Foundation for Sustainability Studies: Terrascope, A Case Study 

      Epstein, Ari W.; Bras, Rafael L.; Bowring, Samuel A. (Springer Japan, 2009-03)
      Terrascope is a freshman learning community at the Massachusetts Institute of Technology (MIT) in which teams of students work to find solutions to large ‘unsolvable’ problems and to communicate about those problems with ...
    • Building a path in cell biology 

      Cheeseman, Iain McPherson; Voeltz, Gia (American Society for Cell Biology, 2012-11)
      Setting up a new lab is an exciting but challenging prospect. We discuss our experiences in finding a path to tackle some of the key current questions in cell biology and the hurdles that we have encountered along the way.
    • Building biomedical materials layer-by-layer 

      Hammond, Paula T. (Elsevier, 2012-05)
      In this materials perspective, the promise of water based layer-by-layer (LbL) assembly as a means of generating drug-releasing surfaces for biomedical applications, from small molecule therapeutics to biologic drugs and ...
    • Building blocks for subleading helicity operators 

      Stewart, Iain; Kolodrubetz, Daniel Walter; Moult, Ian James (Springer Berlin Heidelberg, 2016-05)
      On-shell helicity methods provide powerful tools for determining scattering amplitudes, which have a one-to-one correspondence with leading power helicity operators in the Soft-Collinear Effective Theory (SCET) away from ...
    • Building Fast to Think Faster: Exploiting Rapid Prototyping to Accelerate Ideation During Early Stage Design 

      Neeley, W. Lawrence; Lim, Kirsten B.; Zhu, April; Yang, Maria (ASME International, 2013-08)
      While rapid prototyping has proved to be an invaluable resource for expediting particular phases of the design process, its decreasing cost of operation and increasing accessibility reveal greater potential for these tools ...
    • Building intuition of iron evolution during solar cell processing through analysis of different process models 

      Morishige, Ashley Elizabeth; Laine, Hannu S.; Schön, Jonas; Haarahiltunen, Antti; Hofstetter, Jasmin; e.a. (Springer Berlin Heidelberg, 2015-07)
      An important aspect of Process Simulators for photovoltaics is prediction of defect evolution during device fabrication. Over the last twenty years, these tools have accelerated process optimization, and several Process ...
    • Building machines that learn and think like people 

      Lake, Brenden M.; Ullman, Tomer David; Tenenbaum, Joshua B; Gershman, Samuel J (Cambridge University Press, 2016-11)
      Recent progress in artificial intelligence (AI) has renewed interest in building systems that learn and think like people. Many advances have come from using deep neural networks trained end-to-end in tasks such as object ...
    • BUILDING MANY-CORE PROCESSOR-TO-DRAM NETWORKS WITH MONOLITHIC CMOS SILICON PHOTONICS 

      Batten, Christopher; Joshi, Ajay J.; Orcutt, Jason Scott; Khilo, Anatol M.; Moss, Benjamin Roy; e.a. (Institute of Electrical and Electronics Engineers, 2009-07)
      Silicon photonics is a promising technology for addressing memory bandwidth limitations in future many-core processors. This article first introduces a new monolithic silicon-photonic technology, which uses a standard bulk ...
    • Building Robust Transcriptomes with Master Splicing Factors 

      Sharp, Phillip A.; Jangi, Mohini Rohit (Elsevier, 2014-10)
      Coherent splicing networks arise from many discrete splicing decisions regulated in unison. Here, we examine the properties of robust, context-specific splicing networks. We propose that a subset of key splicing regulators, ...
    • Building Spanning Trees Quickly in Maker-Breaker Games 

      Clemens, Dennis; Ferber, Asaf; Glebov, Roman; Hefetz, Dan; Liebenau, Anita (Society for Industrial and Applied Mathematics, 2015-09)
      For a tree T on n vertices, we study the Maker-Breaker game, played on the edge set of the complete graph on n vertices, which Maker wins as soon as the graph she builds contains a copy of T. We prove that if T has bounded ...
    • Buildup of Choice-Predictive Activity in Human Motor Cortex during Perceptual Decision Making 

      Donner, Tobias H.; Siegel, Markus; Fries, Pascal; Engel, Andreas K. (Elsevier B.V., 2009-09)
