    • On the Worldsheet Derivation of Large N Dualities for the Superstring 

      Berkovits, Nathan; Ooguri, Hirosi; Vafa, Cumrun (Springer (part of Springer Nature), 2004)
      Large N topological string dualities have led to a class of proposed open/ closed dualities for superstrings. In the topological string context, the worldsheet derivation of these dualities has already been given. In this ...
    • On the Yttrium Tantalate – Zirconia phase diagram 

      Gurak, Mary; Flamant, Quentin; Laversenne, Laetitia; Clarke, David (Elsevier BV, 2018-08)
      The phase diagram for the YTaO4-ZrO2 quasi-binary has been determined up to 1600°C. There are three distinct compositional regimes: an extensive YTaO4 solid solution, an extensive ZrO2 solid solution and a two-phase ...
    • On thermodynamic inconsistencies in several photosynthetic and solar cell models and how to fix them 

      David Gelbwaser-Klimovsky; Aspuru-Guzik, Alan (Royal Society of Chemistry (RSC), 2017)
      We analyze standard theoretical models of solar energy conversion developed to study solar cells and photosynthetic systems.
    • On Torque and Tumbling in Swimming Escherichia coli 

      Darnton, Nicholas; Turner, Linda; Rojevsky, Svetlana; Berg, Howard (American Society for Microbiology, 2007)
      Bacteria swim by rotating long thin helical filaments, each driven at its base by a reversible rotary motor. When the motors of peritrichous cells turn counterclockwise (CCW), their filaments form bundles that drive the ...
    • On Transformations of Interactive Proofs that Preserve the Prover's Complexity 

      Vadhan, Salil P. (Association for Computing Machinery, 2000)
      Goldwasser and Sipser [GS89] proved that every interactive proof system can be transformed into a public-coin one (a.k.a., an Arthur-Merlin game). Their transformation has the drawback that the computational complexity of ...
    • On Uncertain Lifetimes 

      Barro, Robert J.; Friedman, James W. (University of Chicago Press, 1977)
      This paper contrasts consumer choice under uncertain lifetimes with the behavior that would arise if each individual's lifetime were announced at birth. In a model that includes life insurance and excludes investments in ...
    • On Unity and Disunity in the Sciences: Variations of Ancient Themata 

      Holton, Gerald (Springer Netherlands, 2010)
    • On using the seasonal cycle to interpret extratropical temperature changes since 1950 

      McKinnon, Karen Aline; Huybers, Peter John (Wiley-Blackwell, 2014)
      Extratropical near-surface air temperature variability is explored on three different time scales: the seasonal cycle, observed changes in temperature since 1950, and the equilibrium response to increasing CO2 in an ...
    • On Waves, Clusters, and Diffusion: A Conceptual Framework 

      Elkins, Zachary; Simmons, Beth (SAGE Publications, 2005)
      This article makes a conceptual and theoretical contribution to the study of diffusion. The authors suggest that the concept of diffusion be reserved for processes (not outcomes) characterized by a certain uncoordinated ...
    • On “Liberation” 

      MacFarquhar, Roderick (Cambridge University Press, 2009)
      When the editor asked me along with other ex-editors to offer some thoughts on the occasion of The China Quarterly's 50th anniversary, I was at a loss. At the celebration which David Shambaugh held for the 35th anniversary ...
    • On “Rethinking” Craft Specialization: Responses by the Authors 

      Hruby, Zachary X.; Flad, Rowan K.; Clark, John E.; Inomata, Takeshi; Miller, Heather M.-L. (American Anthropological Association, 2006)
    • On-chip 3D neuromuscular model for drug screening and precision medicine in neuromuscular disease 

      Osaki, Tatsuya; Uzel, Sebastien G. M.; Kamm, Roger D. (Springer Science and Business Media LLC, 2020-01-13)
    • On-chip electro-optic frequency shifters and beam splitters 

      Hu, Yaowen; Yu, Mengjie; Shams Ansari, Amirhassan; Sinclair, Neil; Holzgrafe, Jeffrey; Puma, Eric; Zhang, Mian; Shao, Linbo; Loncar, Marko (Springer Science and Business Media LLC, 2021-11-24)
      Efficient frequency shifting and beam splitting is important for a wide range of applications, including atomic physics1,2, microwave photonics3–6, optical communication7,8, and photonic quantum computing9–14. However, ...
    • On-chip zero-index metamaterials 

      Li, Yang; Kita, Shota; Munoz, Philip Alejandro; Reshef, Orad; Vulis, Daryl Inna; Yin, Mei; Loncar, Marko; Mazur, Eric (Nature Publishing Group, 2015)
      Metamaterials with a refractive index of zero exhibit physical properties such as infinite phase velocity and wavelength. However, there is no way to implement these materials on a photonic chip, restricting the investigation ...
    • An on-shell approach to factorization 

      Feige, Ilya Eric Alexander; Schwartz, Matthew D (American Physical Society (APS), 2013)
      Factorization is possible due to the universal behavior of Yang-Mills theories in soft and collinear limits. Here, we take a small step towards a more transparent understanding of these limits by proving a form of perturbative ...
    • Oncogenic AKT1(E17K) mutation induces mammary hyperplasia but prevents HER2-driven tumorigenesis 

      Mancini, Maria L.; Lien, Evan C.; Toker, Alex (Impact Journals LLC, 2016)
      One of the most frequently deregulated signaling pathways in breast cancer is the PI 3-K/Akt cascade. Genetic lesions are commonly found in PIK3CA, PTEN, and AKT, which lead to excessive and constitutive activation of Akt ...
    • An oncogenic MYB feedback loop drives alternate cell fates in adenoid cystic carcinoma 

      Drier, Yotam; Cotton, Matthew J.; Williamson, Kaylyn E.; Gillespie, Shawn M.; Ryan, Russell J.H.; Kluk, Michael J.; Carey, Christopher D.; Rodig, Scott J.; Sholl, Lynette M; Afrogheh, Amir H.; Faquin, William C.; Queimado, Lurdes; Qi, Jun; Wick, Michael J.; El-Naggar, Adel K.; Bradner, James E.; Moskaluk, Christopher A.; Aster, Jon C.; Knoechel, Birgit; Bernstein, Bradley E. (2016)
      Translocation events are frequent in cancer and may create chimeric fusions or ‘regulatory rearrangements’ that drive oncogene overexpression. Here we identify super-enhancer translocations that drive overexpression of the ...

      The evolution of surface morphology during ion beam erosion of Si(111) at glancing ion incidence (60o from normal, 500 eV Ar+, 0.75 mA/cm2 collimated beam current) was studied over a temperature range of 500-730o Celsius. ...
    • One Big File Is Not Enough: A Critical Evaluation of the Dominant Free-Space Sanitization Technique 

      Garfinkel, Simson; Malan, David J. (Springer Verlag, 2006)
      Many of today’s privacy-preserving tools create a big file that fills up a hard drive or USB storage device in an effort to overwrite all of the “deleted files” that the media contain. But while this technique is widespread, ...
