    • (1,1) L-space knots 

      Vafaee, Faramarz; Greene, Joshua Evan; Lewallen, Sam (COMPOSITIO MATHEMATICA, 2018-05-01)
      We characterize the (1, 1) knots in the three-sphere and lens spaces that admit non-trivial L-space surgeries. As a corollary, 1-bridge braids in these manifolds admit non- trivial L-space surgeries. We also recover ...
    • A baseline paleoecological study for the Santa Cruz Formation (late–early Miocene) at the Atlantic coast of Patagonia, Argentina 

      Kay, Richard; Vizcaíno, Sergio F; Bargo, M Susana; Fariña, Richard A; Di Giacomo, Mariana; Perry, Jonathan MG; Prevosti, Francisco J; ... (10 authors) (Palaeogeography, Palaeoclimatology, Palaeoecology, 2010-06)
      Coastal exposures of the Santa Cruz Formation (late-early Miocene, southern Patagonia, Argentina) between the Coyle and Gallegos rivers have been a fertile ground for recovery of Miocene vertebrates for more than 100 years. ...
    • A microscopic model of the Stokes-Einstein relation in arbitrary dimension. 

      Charbonneau, Patrick; Charbonneau, Benoit; Szamel, Grzegorz (The Journal of chemical physics, 2018-06)
      The Stokes-Einstein relation (SER) is one of the most robust and widely employed results from the theory of liquids. Yet sizable deviations can be observed for self-solvation, which cannot be explained by the standard ...
    • A slicing obstruction from the $\frac {10}{8}$ theorem 

      Vafaee, Faramarz; Donald, Andrew (Proceedings of the American Mathematical Society, 2016-08-29)
      © 2016 American Mathematical Society. From Furuta’s 10/8 theorem, we derive a smooth slicing obstruction for knots in S3 using a spin 4-manifold whose boundary is 0-surgery on a knot. We show that this obstruction is able ...
    • An Empirical Comparison of Multiple Imputation Methods for Categorical Data 

      Li, Fan; Reiter, Jerome; Akande, Olanrewaju (The American Statistician, 2017-04-03)
      © 2017 American Statistical Association. Multiple imputation is a common approach for dealing with missing values in statistical databases. The imputer fills in missing values with draws from predictive models estimated ...
    • Ballistic Graphene Josephson Junctions from the Short to the Long Junction Regimes. 

      Finkelstein, Gleb; Draelos, Anne; Seredinski, Andrew; Borzenets, IV; Amet, F; Ke, CT; Wei, MT; ... (12 authors) (Physical review letters, 2016-12-02)
      We investigate the critical current I_{C} of ballistic Josephson junctions made of encapsulated graphene-boron-nitride heterostructures. We observe a crossover from the short to the long junction regimes as the length of ...
    • Berge–Gabai knots and L–space satellite operations

      © 2014 Mathematical Sciences Publishers. All rights reserved. Let P(K) be a satellite knot where the pattern P is a Berge–Gabai knot (ie a knot in the solid torus with a nontrivial solid torus Dehn surgery) and the companion ...
    • Bounding the outcome of a two-photon interference measurement using weak coherent states

    • Climate and health impacts of US emissions reductions consistent with 2 °C 

      Shindell, Drew; Lee, Yunha; Faluvegi, Greg (Nature Climate Change, 2016-05)
      © 2016 Macmillan Publishers Limited. All rights reserved. An emissions trajectory for the US consistent with 2 °C warming would require marked societal changes, making it crucial to understand the associated benefits. Previous ...
    • Counterpoint to Obura

    • Generalized optical memory effect

      © 2017 Optical Society of America. The optical memory effect is a well-known type of tilt/tilt wave correlation that is observed in coherent fields, allowing control over scattered light through thin and diffusive materials. ...
    • Inorganic carbon speciation and fluxes in the Congo River 

      Poulsen, John; Wang, Zhaohui Aleck; Bienvenu, Dinga Jean; Mann, Paul J; Hoering, Katherine A; Spencer, Robert GM; Holmes, Robert M (Geophysical Research Letters, 2013-02-16)
      Seasonal variations in inorganic carbon chemistry and associated fluxes from the Congo River were investigated at Brazzaville-Kinshasa. Small seasonal variation in dissolved inorganic carbon (DIC) was found in contrast with ...

    • Large trees drive forest aboveground biomass variation in moist lowland forests across the tropics

      Aim: Large trees (d.b.h.≥70cm) store large amounts of biomass. Several studies suggest that large trees may be vulnerable to changing climate, potentially leading to declining forest biomass storage. Here we determine the ...
