  • Felkner, John; Tazhibayeva, Kamilya; Townsend, Robert (American Economic Association, 2009-05)
    Our goal is to evaluate crop yield impacts from likely climate changes for Southeast Asia. To do so we link soil science crop modeling, weather simulators, and global climate change modeling into an integrated economic ...
  • Jia, Panle; Pathak, Parag (American Economic Association, 2010-05)
    Buying or selling a residential property is one of the most important financial decisions for a large majority of households in the United States. In 2007, 68 percent of households owned their own home, more than a ...
  • Townsend, Robert; Kaboski, Joseph P. (American Economic Association, 2012-04)
    This paper evaluates the short- and longer term impact of Thailand's "Million Baht Village Fund" program, among the largest scale government microfinance iniatives in the world, using pre- and post-program panel data and ...
  • Bertoni, Mariana I.; Hudelson, S.; Newman, B. K.; Bernardis, S.; Fenning, David P.; Dekkers, H. F. W.; Cornagliotti, E.; Zuschlag, A.; Micard, G.; Hahn, G.; Coletti, G.; Lai, B.; Buonassisi, Tonio (Institute of Electrical and Electronics Engineers, 2010-06)
    In this work we examine the effectiveness of hydrogen passivation at grain boundaries as a function of defect type and microstructure in multicrystalline silicon. We analyze a specially prepared solar cell with alternating ...
  • Korolev, Kirill Sergeevich; Sunyaev, Shamil R.; Mirny, Leonid A.; Christopher D., McFarland; Gregory V., Kryukov (National Academy of Sciences (U.S.), 2013-02)
    Cancer progression is driven by the accumulation of a small number of genetic alterations. However, these few driver alterations reside in a cancer genome alongside tens of thousands of additional mutations termed passengers. ...
  • Cohen, Jason Blake; Prinn, Ronald G.; Wang, Chien (American Geophysical Union (AGU), 2011-05)
    Detailed urban-scale processing has not been included in global 3D chemical transport models due to its large computational demands. Here we present a metamodel for including this processing, and compare it with the use ...
  • Nepf, Heidi; Andradottir, Hrund O. (American Geophysical Union, 2001-12)
    The flushing of littoral regions is governed by barotropic river flows, QR, and baroclinic exchange flows, ΔQ. This note presents field observations of two different flushing regimes in a shallow wetland that borders a ...
  • Walton, Esther; Geisler, Daniel; Hass, Johanna; Liu, Jingyu; Turner, Jessica; Yendiki, Anastasia; Smolka, Michael N.; Ho, Beng-Choon; Manoach, Dara S.; Roessner, Veit; Calhoun, Vince D.; Ehrlich, Stefan; Gollub, Randy Lyanne (Public Library of Science, 2013-10)
    The neural mechanisms underlying genetic risk for schizophrenia, a highly heritable psychiatric condition, are still under investigation. New schizophrenia risk genes discovered through genome-wide association studies ...
  • Bita, Ion; Thomas, Edwin L.; Jia, Lin (American Physical Society (APS), 2011-11)
    Here we demonstrate a novel quantitative procedure to pursue statistical studies on the geometric properties of photonic crystals and photonic quasicrystals (PQCs) which consist of separate dielectric particles. The geometric ...
  • Simaiakis, Ioannis; Donaldson, Alexander; Balakrishnan, Hamsa (American Institute of Aeronautics and Astronautics, 2011-09)
    Aviation System Performance Metrics (ASPM) departure and arrival rate data is collected for four common airport confi gurations at Newark Liberty International Airport (EWR) under Visual Meteorological Conditions (VMC) for ...
  • Flores, Alejandro N.; Ivanov, Valeriy Y.; Entekhabi, Dara; Bras, Rafael L. (Institute of Electrical and Electronics Engineers, 2009-04)
    Microwave radiometry will emerge as an important tool for global remote sensing of near-surface soil moisture in the coming decade. In this modeling study, we find that hillslope-scale topography (tens of meters) influences ...
  • Cordero Sanchez, Otto Xavier; Hogeweg, Paulien (National Academy of Sciences (U.S.), 2009-12)
    Horizontal gene transfer (HGT) is one of the most dominant forces molding prokaryotic gene repertoires. These repertoires can be as small as ≈200 genes in intracellular organisms or as large as ≈9,000 genes in large, ...
  • Edmonds, Eric V; Shrestha, Maheshwor (Springer, 2012-12)
    Promoting minimum age of employment regulation has been a centerpiece in child labor policy for the last 15 years. If enforced, minimum age regulation would change the age profile of paid child employment. Using micro-data ...
  • Borgne, Marie Le; Ladi, Ena; Dzhagalov, Ivan; Herzmark, Paul; Liao, Ying Fang; Chakraborty, Arup K.; Robey, Ellen A. (Nature Publishing Group, 2009-06)
    Developing thymocytes are screened for self-reactivity before they exit the thymus, but how thymocytes scan the medulla for self antigens is unclear. Using two-photon microscopy, we observed that medullary thymocytes ...
  • Lei, Wenfang; Zavala, M.; de Foy, B.; Volkmer, R.; Molina, Mario J.; Molina, Luisa Tan (Copernicus Publications on behalf of the European Geophysical Society, 2009-04)
    Formaldehyde (HCHO) is a radical source that plays an important role in urban atmospheric chemistry and ozone formation. The Mexico City Metropolitan Area (MCMA) is characterized by high anthropogenic emissions of HCHO ...
  • Jagannathan, Krishna Prasanna; Modiano, Etyan H. (International League Against Epilepsy, 2009-10)
    We consider a system consisting of N parallel queues, served by one server. Time is slotted, and the server serves one of the queues in each time slot, according to some scheduling policy. In the first part of the paper, ...
  • Dai, Lillian L.; Chan, Vincent W. S. (Institute of Electrical and Electronics Engineers, 2009-03)
    Throughput scaling and optimal hop distance of interference-limited wireless networks have been well characterized in literature. For some emerging wireless networks, throughput may be more limited by battery energy rather ...
  • Amini, Alexander A.; Kung, Kevin; Kang, Chaogui; Sobolevsky, Stanislav; Ratti, Carlo (Springer Science+Business Media, 2014)
    This study leverages mobile phone data to analyze human mobility patterns in a developing nation, especially in comparison to those of a more industrialized nation. Developing regions, such as the Ivory Coast, are marked ...
  • Chen, Yan; Cai, Zhuhua; Kim, Jae Jin; Tuller, Harry L.; Yildiz, Bilge; Jung, Woo Chul (Royal Society of Chemistry, 2012-04)
    The correlation between the surface chemistry and electronic structure is studied for SrTi[subscript 1−x]Fe[subscript x]O[subscript 3] (STF), as a model perovskite system, to explain the impact of Sr segregation on the ...
  • Kim, Donghun; Kim, Dong-Ho; Lee, Joo-Hyoung; Grossman, Jeffrey C. (American Physical Society, 2013-05)
    Although the stoichiometry of bulk lead sulfide (PbS) is exactly 1∶1, that of quantum dots (QDs) can be considerably different from this crystalline limit. Employing first-principles calculations, we show that the impact ...
