  • Kleinke, Andrew S.; Jamison, Timothy F.; Jamison, Timothy F. (American Chemical Society (ACS), 2013-01)
    The first continuous hydrogenation that requires neither H[subscript 2] nor metal catalysis generates diimide by a novel reagent combination. The simple flow reactor employed minimizes residence time by enabling safe ...
  • Sheng, Wenchao; Gasteiger, Hubert A.; Shao-Horn, Yang (The Electrochemical Society, 2010-09)
    The kinetics of the hydrogen oxidation reaction (HOR) and hydrogen evolution reaction (HER) on polycrystalline platinum [Pt(pc)] and high surface area carbon-supported platinum nanoparticles (Pt/C) were studied in 0.1 M ...
  • Sartoretto, Juliano; Kalwa, Hermann; Pluth, Michael D.; Lippard, Stephen J. (National Academy of Sciences, 2011-09)
    Nitric oxide (NO) and hydrogen peroxide (H(subscript 2)O(subscript 2)) are synthesized within cardiac myocytes and play key roles in modulating cardiovascular signaling. Cardiac myocytes contain both the endothelial (eNOS) ...
  • Yip, Sidney; Lau, Timothy T.; Van Vliet, Krystyn J.; Monasterio, Paul Rene (American Physical Society, 2009-08)
    Energetics and concentrations of hydrogen-containing point defect clusters (PDCs) in Fe-C alloys are calculated and cast into a PDC dominance diagram. Because of the strong binding effects of iron vacancies on the stability ...
  • Fenty, Ian; Heimbach, Patrick (American Meteorological Society, 2013-05)
    This study investigates the hydrographic processes involved in setting the maximum wintertime sea ice (SI) extent in the Labrador Sea and Baffin Bay. The analysis is based on an ocean and sea ice state estimate covering ...
  • Demory, Marie-Estelle; Eltahir, Elfatih A. B.; Siam, Mohamed Salah (American Meteorological Society, 2013-11)
    The simulations and predictions of the hydrological cycle by general circulation models (GCMs) are characterized by a significant degree of uncertainty. This uncertainty is reflected in the range of Intergovernmental Panel ...
  • Flores, Alejandro N.; Bras, Rafael L.; Entekhabi, Dara (American Geophysical Union, 2012-08)
    [1] Soil moisture information is critical for applications like landslide susceptibility analysis and military trafficability assessment. Existing technologies cannot observe soil moisture at spatial scales of hillslopes ...
  • Gianotti, Rebecca Louise; Bomblies, Arne; Eltahir, Elfatih A. B. (American Geophysical Union, 2009-08)
    This paper describes the first use of Hydrology-Entomology and Malaria Transmission Simulator (HYDREMATS), a physically based distributed hydrology model, to investigate environmental management methods for malaria vector ...
  • Yu, Winston; Yang, Yi-Chen; Savitsky, Andre; Alford, Donald; Brown, Casey; Wescoat, James; Debowicz, Dario; Robinson, Sherman (The World Bank, 2013-04)
    Examines the state of the science associated with the snow and ice hydrology in the Upper Indus Basin (IUB), reviewing the literature and data available on the present and projected role of glaciers, snow fields, and stream ...
  • Larson, Alyssa Maxine; Hsu, Bryan Boen; Rautaray, Debabrata; Haldar, Jayanta; Chen, Jianzhu; Klibanov, Alexander M. (Wiley Blackwell (John Wiley & Sons), 2010-10)
    Coating surfaces with N-alkylated polyethylenimines (PEIs), namely branched N,N-hexyl,methyl-PEI via covalent attachment to glass or linear N,N-dodecyl,methyl-PEI by physical deposition (“painting”) onto polyethylene, ...
  • Davies, Bryan W.; Kohanski, Michael A.; Simmons, Lyle A.; Winkler, Jonathan A.; Collins, James J.; Walker, Graham C. (Elsevier B.V., 2009-12)
    Hydroxyurea (HU) specifically inhibits class I ribonucleotide reductase (RNR), depleting dNTP pools and leading to replication fork arrest. Although HU inhibition of RNR is well recognized, the mechanism by which it leads ...
  • Barak, Boaz; Brandao, Fernando G.S.L.; Harrow, Aram W.; Steurer, David; Zhou, Yuan; Kelner, Jonathan Adam (Association for Computing Machinery (ACM), 2012-05)
    We study the computational complexity of approximating the 2-to-q norm of linear operators (defined as |A|[subscript 2->q] = max[subscript v≠ 0]|Av|[subscript q]/|v|[subscript 2]) for q > 2, as well as connections between ...
  • Kedlaya, Kiran S.; Sutherland, Andrew Victor (American Mathematical Society, 2009-01)
    We analyze the distribution of unitarized L-polynomials Lp(T) (as p varies) obtained from a hyperelliptic curve of genus g [less than or equal to] 3 defined over Q. In the generic case, we find experimental agreement with ...
  • Unknown author (American Physical Society, 2013-02)
    We use hyperentangled photons to experimentally implement an entanglement-assisted quantum process tomography technique known as direct characterization of quantum dynamics. Specifically, hyperentanglement-assisted Bell-state ...
  • Tiburzi, Brian C.; Jiang, Fu-Jiun (American Physical Society, 2010-02)
    The pion-mass dependence of hyperon electromagnetic properties is determined using two-flavor heavy baryon chiral perturbation theory. Specifically we compute chiral corrections to the charge radii, magnetic moments, and ...
  • Beane, S. R.; Chang, E.; Cohen, S. D.; Detmold, William; Lin, H. W.; Luu, T. C.; Orginos, K.; Savage, M. J.; Walker-Loud, A.; Parreno, A. (American Physical Society, 2012-10)
    The low-energy nΣ[superscript -] interactions determine, in part, the role of the strange quark in dense matter, such as that found in astrophysical environments. The scattering phase shifts for this system are obtained ...
  • Fraser, Cameron S.; Bertuccelli, Luca F.; Choi, Han-Lim; How, Jonathan P. (Institute of Electrical and Electronics Engineers, 2010-07)
    This paper addresses the problem of information consensus in a team of networked agents with uncertain local estimates described by parameterized distributions in the exponential family. In particular, the method utilizes ...
  • Pacula, Maciej; Ansel, Jason Andrew; Amarasinghe, Saman P.; O'Reilly, Una-May (Springer Berlin / Heidelberg, 2012-03)
    We are using bandit-based adaptive operator selection while autotuning parallel computer programs. The autotuning, which uses evolutionary algorithm-based stochastic sampling, takes place over an extended duration and ...
  • Osterweil, Emily; Krueger, Dilja D.; Reinhold, Kimberly; Bear, Mark (Society for Neuroscience, 2010-11)
    Fragile X syndrome (FXS) is caused by loss of the FMR1 gene product FMRP (fragile X mental retardation protein), a repressor of mRNA translation. According to the metabotropic glutamate receptor (mGluR) theory of FXS, ...
