    Changes in the D/H ratio of sedimentary organic matter (SOM) during thermal maturation have been difficult to interpret because the effects of hydrogen exchange and kinetic fractionations are confounded in natural samples. Recent analytical developments have significant...

    The TMT mount control system provides telescope pointing and tracking. Requirements include wind disturbance rejection, offsetting time and accuracy, control system robustness, and the magnitude of response at structural resonances. A finite element model of the complet...

    Searches for resonances decaying into pairs of jets are performed using proton-proton collision data collected at √s = 13 TeV corresponding to an integrated luminosity of up to 36 fb^(−1). A low-mass search, for resonances with masses between 0.6 and 1.6 TeV, is perform...

    We have completed a feasibility study for the measurement of weak distortion of distant galaxy images by intervening large-scale structure by using the 5-m Hale reflector to acquire a very deep, r ~ 26, exposure of a single field. The error budget of our observations is...

    It was mentioned in a previous letter to the Physical Review(1) that lithium, when bombarded with protons gave a measurable intensity of neutrons. The effect has since been investigated further, and a curve plotted of the yield of neutrons as a function of voltage from ...

    <jats:p>Abstract. In atmospheric aerosols, water and volatile inorganic and organic species are distributed between the gas and aerosol phases in accordance with thermodynamic equilibrium. Within an atmospheric particle, liquid and solid phases can exist at equilibrium....

    Described in this report is an enantioselective route toward the chamigrene natural product family. The key disconnections in our synthetic approach include sequential enantioselective decarboxylative allylation and ring-closing olefin metathesis to form the all-carbon ...

    The article describes an investigation of the absorption spectrum of ammonia gas in the visible region. At 5490A an absorption region was found which was too weak for a complete investigation with the means at hand. On a second band at 6474A measurements on 57 lines are...

    By studying the alpha-particles emitted in the disintegration of B10 by protons it has been shown that there exists an excited state in Be7 at 434.4±4 kev which corresponds to the well-known first excited state in the mirror nucleus, Li7. Measurements on the inelastic s...
