    • Nuclear asset shutdown under uncertainty 

      Haratyk, Geoffrey (Massachusetts Institute of Technology, 2017)
      The restructuring of the power sector that began in the 1990s created acute competition for nuclear power plants. While merchant reactors benefited from this change in the early years, recently they started to retire for ...
    • Nuclear bargaining : using carrots and sticks in nuclear counter-proliferation 

      Reardon, Robert J (Massachusetts Institute of Technology, 2010)
      This dissertation explores how states can use positive inducements and negative sanctions to successfully bargain with nuclear proliferators and prevent the spread of nuclear weapons. It seeks to answer the following ...
    • Nuclear Cloning and Direct Reprogramming: The Long and the Short Path to Stockholm 

      Jaenisch, Rudolf (Elsevier, 2012-12)
      This year’s Nobel Prize in Physiology or Medicine was awarded to John Gurdon and Shinya Yamanaka for solving key problems of biology. Their work provided fundamental insights into how an egg gives rise to a complex organism ...
    • The nuclear contacts and short range correlations in nuclei 

      Weiss, R.; Cruz-Torres, R.; Barnea, N.; Piasetzky, E.; Cruz Torres, Reynier; e.a. (Elsevier, 2018-02)
      Atomic nuclei are complex strongly interacting systems and their exact theoretical description is a long-standing challenge. An approximate description of nuclei can be achieved by separating its short and long range ...
    • Nuclear correlation functions in lattice QCD 

      Detmold, William; Orginos, Kostas (American Physical Society, 2013-06)
      We consider the problem of calculating the large number of Wick contractions necessary to compute states with the quantum numbers of many baryons in lattice QCD. We consider a constructive approach and a determinant-based ...
    • Nuclear criticality as a contributor to gamma ray burst events 

      Hayes, Robert B. (Springer Netherlands, 2013-01)
      Most gamma ray bursts are able to be explained using supernovae related phenomenon. Some measured results still lack compelling explanations and a contributory cause from nuclear criticality is proposed. This is shown to ...
    • Nuclear disarmament verification via resonant phenomena 

      Hecla, Jake J.; Danagoulian, Areg (Nature Publishing Group, 2018-03)
      Nuclear disarmament treaties are not sufficient in and of themselves to neutralize the existential threat of the nuclear weapons. Technologies are necessary for verifying the authenticity of the nuclear warheads undergoing ...
    • Nuclear double resonance between statistical spin polarizations 

      Poggio, M.; Mamin, H. J.; Degen, Christian; Sherwood, M. H.; Rugar, D. (American Physical Society, 2009-02)
      We demonstrate nuclear double resonance for nanometer-scale volumes of spins where random fluctuations rather than Boltzmann polarization dominate. When the Hartmann-Hahn condition is met in a cross-polarization experiment, ...
    • Nuclear effects in neutrino and antineutrino charged-current quasielastic scattering at MINERvA kinematics 

      Megias, G. D.; Ivanov, M. V.; Barbaro, M. B.; Caballero, J. A.; Donnelly, T. William; e.a. (American Physical Society, 2014-05)
      We compare the charged-current quasielastic neutrino and antineutrino observables obtained in two different nuclear models, the phenomenological SuperScaling Approximation and the relativistic mean field approach, with the ...
    • Nuclear effects on the transverse momentum spectra of charged particles in pPb collisions at √s[subscript NN] = 5.02 TeV 

      Apyan, Aram; Barbieri, Richard Alexander; Bauer, Gerry P.; Busza, Wit; Cali, Ivan Amos; e.a. (Springer-Verlag, 2015-05)
      Transverse momentum spectra of charged particles are measured by the CMS experiment at the CERN LHC in pPb collisions at √s[subscript NN] = 5.02 TeV, in the range 0.4 < p[subscript T] < 120 GeV/c and pseudorapidity ...
    • Nuclear electric propulsion : assessing the design of Project Prometheus. 

      Goycoolea, Martin (Massachusetts Institute of Technology, 2013)
      The high fuel efficiency of electric propulsion makes it a viable alternative for long-distance space travel. Project Prometheus was a NASA-led project that sought to demonstrate that distant electric propulsion missions ...
    • Nuclear Energy for Simultaneous Low-Carbon Heavy-Oil Recovery and Gigawatt-Year Heat Storage for Peak Electricity Production 

      Forsberg, Charles W.; Krentz-Wee, Rebecca E.; Lee, You Ho; Oloyede, Isaiah O. (Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Nuclear Energy and Sustainability Program, 2010-12)
      In a carbon-constrained world or a world of high natural gas prices, the use of fossil-fueled power plants to satisfy variable electricity demands may be limited. Nuclear power plants operating at full capacity with ...
    • Nuclear Energy for Variable Electricity and Liquid Fuels Production: Integrating Nuclear with Renewables, Fossil Fuels, and Biomass for a Low- Carbon World 

      Forsberg, Charles W. (Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Nuclear Energy and Sustainability Program, 2011-09)
      The world faces two energy challenges: (1) the national security and economic challenge of dependence on foreign oil and (2) the need to reduce carbon dioxide emissions from the burning of fossil fuels to avoid climate ...
    • Nuclear Energy Options for Hydrogen and Hydrogen-Based Liquid Fuels Production 

      Yildiz, Bilge; Kazimi, Mujid S. (Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Nuclear Energy and Sustainability Program, 2003-09)
      Nuclear energy can be used for hydrogen production through thermochemical or electrochemical processes for splitting water (and/or steam) into its elemental parts. The overall performance of alternative routes for using ...
    • Nuclear Factor I/B is an Oncogene in Small Cell Lung Cancer 

      Dooley, Alison L.; Winslow, Monte Meier; Chiang, Derek Y.; Banerji, Shantanu; Stransky, Nicolas; e.a. (Cold Spring Harbor Laboratory Press in association with The Genetics Society, 2011-10)
      Small cell lung cancer (SCLC) is an aggressive cancer often diagnosed after it has metastasized. Despite the need to better understand this disease, SCLC remains poorly characterized at the molecular and genomic levels. ...
