  • Koutsoyiannis, D.; Makropoulos, C.; Langousis, Andreas; Baki, S.; Efstratiadis, A.; Christofides, A.; Karavokiros, G.; Mamassis, N. (European Geosciences Union / Copernicus, 2009-02)
    Since 1990 extensive funds have been spent on research in climate change. Although Earth Sciences, including climatology and hydrology, have benefited significantly, progress has proved incommensurate with the effort and ...
  • Jones, Kevin C.; Ganim, Ziad; Tokmakoff, Andrei (American Chemical Society, 2009-11)
    We develop heterodyned dispersed vibrational echo spectroscopy (HDVE) and demonstrate the new capabilities in biophysical applications. HDVE is a robust ultrafast technique that provides a characterization of the real and ...
  • Ren, Y.; Gao, J. R.; Hovenier, J. N.; Higgins, R.; Zhang, W.; Bell, A.; Klein, B.; Klapwijk, T. M.; Shi, S. C.; Kao, Tsung-Yu; Kumar, S.; Hu, Qing; Reno, J. L. (SPIE, 2010-07)
    High-resolution heterodyne spectrometers operating at above 2 THz are crucial for detecting, e.g., the HD line at 2.7 THz and oxygen OI line at 4.7 THz in astronomy. The potential receiver technology is a combination of a ...
  • Yao, Huajian; van der Hilst, Robert D.; Montagner, Jean-Paul (American Geophysical Union, 2010-12)
    Understanding the geotectonic evolution of the southeastern Tibetan plateau requires knowledge about the structure of the lithosphere. Using data from 77 broadband stations in SW China, we invert Rayleigh wave phase velocity ...
  • Ryan, Stephen; Tucker, Catherine Elizabeth (Springer-Verlag, 2011-08)
    We estimate the demand for a videocalling technology in the presence of both network effects and heterogeneity. Using a unique dataset from a large multinational firm, we pose and estimate a fully dynamic model of technology ...
  • Abaluck, Jason; Gruber, Jonathan (American Economic Association, 2011-05)
    This paper investigates the degree to which choice inconsistencies documented in the context of Medicare Part D plan choice vary across consumers and geographic regions. Our main finding is that there is surprisingly little ...
  • Weis, Victoria G.; Sousa, Josane F.; LaFleur, Bonnie J.; Nam, Ki Taek; Weis, Jared A.; Finke, Paul E.; Ameen, Nadia A.; Fox, James G.; Goldenrign, James R. (BMJ Publishing Group, 2012-07)
    Objectives: Spasmolytic polypeptide-expressing metaplasia (SPEM) develops as a preneoplastic lesion in the stomachs of mice and humans after parietal cell loss. To identify the commonalities and differences between phenotypic ...
  • Hu, Jie; Locasale, Jason W; Bielas, Jason H; O'Sullivan, Jacintha; Sheahan, Kieran; Cantley, Lewis C; Vander Heiden, Matthew G.; Vitkup, Dennis (Nature Publishing Group, 2013-04)
    Reprogramming of cellular metabolism is an emerging hallmark of neoplastic transformation. However, it is not known how the expression of metabolic genes in tumors differs from that in normal tissues, or whether different ...
  • 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 ...
  • 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 ...
  • Miller, B. R.; Rigby, Matthew; Kuijpers, L. J. M.; Krummel, P. B.; Steele, L. P.; Leist, M.; Fraser, P. J.; McCulloch, A.; Harth, C.; Salameh, P.; Muhle, J.; Weiss, R. F.; Prinn, Ronald G.; Wang, R. H. J.; O'Doherty, S.; 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 ...
  • García, 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 ...
  • 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. (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 ...
