      Csáki, Csaba; Randall, Lisa (Springer Nature, 2016)
      Recent LHC data hinted at a 750 GeV mass resonance that decays into two photons. A significant feature of this resonance is that its decays to any other Standard Model particles would be too low to be detected so far. Such ...

      A kagome lattice of 3d transition metal ions is a versatile platform for correlated topological phases hosting symmetry-protected electronic excitations and magnetic ground states. However, the paradigmatic states of the ...
    • The Direct and Ecological Costs of an Ant-Plant Symbiosis 

      Frederickson, Megan E.; Ravenscraft, Alison; Miller, Gabriel; Hernández, Lina M. Arcila; Booth, Gregory; Pierce, Naomi Ellen (University of Chicago Press, 2012)
      How strong is selection for cheating in mutualisms? The answer depends on the type and magnitude of the costs of the mutualism. Here we investigated the direct and ecological costs of plant defense by ants in the association ...
    • Direct and indirect forms of non-suicidal self-injury: Evidence for a distinction 

      St. Germain, Sarah Ann; Hooley, Jill Miranda (Elsevier BV, 2012)
      Non-suicidal self-injury (NSSI) involves deliberate acts (such as cutting) that directly damage the body but occur without suicidal intent. However, other non-suicidal behaviors that involve people mistreating or abusing ...
    • Direct Bulk-Synchronous Parallel Algorithms 

      Gerbessiotis, A.V.; Valiant, Leslie G. (Elsevier BV, 1994)
      We describe a methodology for constructing parallel algorithms that are transportable among parallel computers having different numbers of processors, different bandwidths of interprocessor communication and different ...
    • Direct Characterization of Cis-Regulatory Elements and Functional Dissection of Complex Genetic Associations Using HCR–FlowFISH 

      Reilly, Steven; Gosai, Sager J.; Gutierrez, Alan; Mackay-Smith, Ava; Ulirsch, Jacob; Kanai, Masahiro; Mouri, Kousuke; Berenzy, Daniel; Kales, Susan; Butler, Gina M.; Gladden-Young, Adrianne; Bhuiyan, Redwan M.; Stitzel, Michael L.; Finucane, Hilary K.; Sabeti, Pardis; Tewhey, Ryan (Springer Science and Business Media LLC, 2021-07-29)
      Abstract: Effective interpretation of genome function and genetic variation requires a shift from epigenetic mapping of cis-regulatory elements (CREs) to characterization of endogenous function. We developed HCR-FlowFISH, ...

      Gilby, Ian C.; Pokempner, Amy; Wrangham, Richard W. (Karger, 2010)
      Focal sampling is the most accurate method for measuring primate activity budgets, but is sometimes impractical. An alternative is scan sampling, in which the behaviour of the group is recorded at regular intervals. The ...
