    The data is saved as .csv files and can be viewed in Microsoft Excel workbook and/or R statistical software. The data was collected at field and entered into master files, from which the data to create the .csv files was taken.Six cover crop treatments were interseeded into maize at two distinct timings: at the four to six-leaf collar stage and at physiological maturity. The canopy cover and biomass of cover crops, soil moisture at planting maize, and maize biomass and yield were evaluated to determine the potential impacts of interseeded cover crops on maize productivity.Minnesota Corn Researh & Promotion CouncilMnDRIVE Global Food Ventures FellowshipRusch, Hannah L; Garcia y Garcia, Axel; Coulter, Jeffrey A; Johnson, Gregg A; Grossman, Julie M; Porter, Paul M.

    A 2 h periodic variation in the low-mass X-ray binary Ser X-1

    No full text
    Spectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1

    [Letter from John J. Herrera to Eleanor R. Garcia - July 31, 1963]

    Onionskin paper carbon copy of letter from John J. Herrera to Eleanor R. Garcia from the V.A. Hospital where Gus Garcia is a patient. Herrera writes that Gus may have to stay in the hospital for a long time, and Herrera is trying to renew Gus's license, so that he can continue to practice law. Herrera asks Eleanor ("Norah") and Garcia's daughters to write to Gus often, as that may aid his recovery

    Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV

    No full text
    The prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region

    Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′

    First evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
