  • Chen, Hui; Joslin, Scott Stephen Walter; Tran, Ngoc-Khanh (American Economic Association, 2010-01)
    We illustrate the effects of heterogeneous beliefs about disasters on the equity premium and individual agents’ trading activities. When investors disagree about the chances or severity of disasters, those optimistic ...
  • Wilson, Kevin R.; Kroll, Jesse; Lim, Christopher Yung-Ta; Kessler, Sean (American Chemical Society (ACS), 2015-09)
    Atmospheric oxidation reactions are known to affect the chemical composition of organic aerosol (OA) particles over timescales of several days, but the details of such oxidative aging reactions are poorly understood. In ...
  • Rodrigues, J. L.; Araujo, R. G.; Prather, Kristala L. Jones; Kluskens, L. D.; Rodrigues, L. R. (Elsevier, 2015-01)
    Caffeic acid is a plant secondary metabolite and its biological synthesis has attracted increased attention due to its beneficial effects on human health. In this study, Escherichia coli was engineered for the production ...
  • Jungreis, Irwin; Kellis, Manolis; Chan, Clara Sophia (Public Library of Science, 2013-03)
    Recent analysis of genomic signatures in mammals, flies, and worms indicates that functional translational stop codon readthrough is considerably more abundant in metazoa than previously recognized, but this analysis ...
  • Paepe, Gael De; Lewandowski, Jozef R.; Loquet, Antoine; Eddy, Matthew Thomas; Megy, Simon; Bockmann, Anja; Griffin, Robert Guy (American Institute of Physics (AIP), 2011-03)
    We describe a theoretical framework for understanding the heteronuclear version of the third spin assisted recoupling polarization transfer mechanism and demonstrate its potential for detecting long-distance intramolecular ...
  • Palmer, Christopher; Hausman, Jerry A. (Elsevier, 2012-02)
    Since the advent of heteroskedasticity-robust standard errors, several papers have proposed adjustments to the original White formulation. We replicate earlier findings that each of these adjusted estimators performs quite ...
  • Hohm, Olaf; Sen, Ashoke; Zwiebach, Barton (Springer Berlin Heidelberg, 2015-02)
    The dimensional reduction of heterotic supergravity with gauge fields truncated to the Cartan subalgebra exhibits a continuous O(d, d + 16; ℝ) global symmetry, related to the O(d, d + 16; ℤ) T-duality of heterotic strings ...
  • Witwicki, Stefan J.; Oliehoek, Frans A.; Kaelbling, Leslie P. (Association for Computing Machinery (ACM), 2012-06)
    Multiagent planning under uncertainty has seen important progress in recent years. Two techniques, in particular, have substantially advanced efficiency and scalability of planning. Multiagent heuristic search gains traction ...
  • Miller, Benjamin R.; Rigby, Matthew; Kuijpers, L. J. M.; Krummel, P. B.; Steele, L. P.; Leist, Michael; Fraser, P. J.; McCulloch, A.; Harth, C. M.; Salameh, P.; Muhle, Jens; Weiss, R. F.; Prinn, Ronald G.; Wang, R. H. J.; O'Doherty, Simon; Greally, B. R.; Simmonds, P. G. (European Geosciences Union, 2010-08)
    HFC-23 (also known as CHF3 [CHF subscript 3], fluoroform or trifluoromethane) is a potent greenhouse gas (GHG), with a global warming potential (GWP) of 14 800 for a 100-year time horizon. It is an unavoidable by-product ...
  • Garcia, Alexis; Zeng, Yu; Muthupalani, Sureshkumar; Ge, Zhongming; Potter, Amanda; Mobley, Melissa W.; Boussahmain, Chakib; Feng, Yan; Wishnok, John S.; Fox, James G. (American Association for Cancer Research, 2011-02)
    Chronic microbial infection influences cancer progression, but the mechanisms that link them remain unclear. Constitutive androstane receptor (CAR) is a nuclear receptor that regulates enzymes involved in endobiotic and ...
  • van Berkum, Nynke L.; Lieberman-Aiden, Erez; Williams, Louise; Gnirke, Andreas; Mirny, Leonid A.; Dekker, Job; Lander, Eric S.; Imakaev, Maksim Viktorovich (MyJoVE Corporation, 2010-05)
    The three-dimensional folding of chromosomes compartmentalizes the genome and and can bring distant functional elements, such as promoters and enhancers, into close spatial proximity. Deciphering the relationship between ...
  • Repeta, Daniel J.; Rothman, Daniel H.; Xu, Li; Santinelli, Chiara; Follett, Christopher (National Academy of Sciences (U.S.), 2014-11)
    Marine dissolved organic carbon (DOC) is a large (660 Pg C) reactive carbon reservoir that mediates the oceanic microbial food web and interacts with climate on both short and long timescales. Carbon isotopic content ...
  • Tan, Longzhi; Serene, Stephen R.; Chao, Hui Xiao; Gore, Jeff (American Physical Society, 2011-05)
    In biological evolution, adaptations to one environment can in some cases reverse adaptations to another environment. To study this “reverse evolution” on a genotypic level, we measured the fitness of E. coli strains with ...
  • Langs, Georg; Paragios, Nikos; Essafi, Salma (Institute of Electrical and Electronics Engineers, 2010-05)
    In this paper, we propose a novel representation of prior knowledge for image segmentation, using diffusion wavelets that can reflect arbitrary continuous interdependencies in shape data. The application of diffusion ...
  • Barry, Jennifer; Kaelbling, Leslie P.; Lozano-Perez, Tomas (Institute of Electrical and Electronics Engineers (IEEE), 2013-05)
    We define the Diverse Action Manipulation (DAMA) problem in which we are given a mobile robot, a set of movable objects, and a set of diverse, possibly non-prehensile manipulation actions, and the goal is to find a sequence ...
  • Wu, Wei; Chen, Zhe; Gao, Shangkai; Brown, Emery N. (Elsevier, 2011-03)
    Multichannel electroencephalography (EEG) offers a non-invasive tool to explore spatio-temporal dynamics of brain activity. With EEG recordings consisting of multiple trials, traditional signal processing approaches that ...
  • Wu, Wei; Chen, Zhe; Gao, Shangkai; Brown, Emery N. (Institute of Electrical and Electronics Engineers, 2010-06)
    In numerous neuroscience studies, multichannel EEG data are often recorded over multiple trial periods under the same experimental condition. To date, little effort is aimed to learn spatial patterns from EEG data to account ...
  • Yu, Jiangbo; Low, Kian Hsiang; Oran, Ali; Jaillet, Patrick (Institute of Electrical and Electronics Engineers (IEEE), 2012-12)
    Route prediction is important to analyzing and understanding the route patterns and behavior of traffic crowds. Its objective is to predict the most likely or "popular" route of road segments from a given point in a road ...
  • Kiritani, Taro; Wickersham, Ian R.; Seung, H. Sebastian; Shepherd, Gordon M. G. (Society for Neuroscience, 2012-04)
    The generation of purposive movement by mammals involves coordinated activity in the corticospinal and corticostriatal systems, which are involved in different aspects of motor control. In the motor cortex, corticospinal ...
  • Johnson, Matthew James; Willsky, Alan S (Association for Uncertainty in Artificial Intelligence (AUAI), 2010)
    There is much interest in the Hierarchical Dirichlet Process Hidden Markov Model (HDP-HMM) as a natural Bayesian nonparametric extension of the traditional HMM. However, in many settings the HDP-HMM's strict Markovian ...
