  • Yamamura, Yasuko; Hua, Xianxin; Bergelson, Svetlana; Lodish, Harvey F. (Hindawi Publishing Corporation, 2001)
    Transforming growth factor-β1 (TGF-β1) induces not only cell growth inhibition but also apoptosis in hepatocytes, myeloid cells, and epithelial cells. Smad complexes (Smad2-Smad4 and Smad3-Smad4) are identified as key ...
  • Podolsky, Dmitry; Turitsyn, Konstantin (Institute of Electrical and Electronics Engineers (IEEE), 2014-11)
    We consider stochastic electro-mechanical dynamics of an overdamped power system in the vicinity of the saddle-node bifurcation associated with the loss of global stability such as voltage collapse or phase angle instability. ...
  • Demirtas, Sefa; del Alamo, Jesus A. (Institute of Electrical and Electronics Engineers, 2009-11)
    We have evaluated the electrical reliability of GaN HEMTs on Si by carrying out V[subscript DS] = 0 V step-stress experiments. We have found that these devices show a degradation pattern that is very similar to that of ...
  • Fox, Jacob; Loh, Po-Shen; Zhao, Yufei (Springer-Verlag/Bolyai Society, 2014-10)
    Ramsey-Turán result proved by Szemerédi in 1972: any K [subscript 4-]free graph on n vertices with independence number o(n) has at most (1[over]8+o(1))n[superscript 2] edges. Four years later, Bollobás and Erdős gave a ...
  • Stiny, George N. (Springer Basel, 2016-01)
    Shape grammars include Wilde’s aesthetic (critical) method—I can calculate with shapes as in themselves they really are not. Embedding makes this possible with schemas and rules that are “superb in [their] changes and ...
  • Bird, Simeon; Kamionkowski, Marc; Creque-Sarbinowski, Cyril (American Physical Society, 2016-09)
    Large-angle fluctuations in the cosmic microwave background temperature induced by the integrated Sachs-Wolfe effect and Compton-y distortions from the thermal Sunyaev-Zeldovich (tSZ) effect are both due to line-of-sight ...
  • Jackson, Jean E. (New York Academy of Sciences, 2009-08)
    Many kinds of body/mind practices are capable of producing remarkable behaviors and altered body states. A typology of such behaviors and states, defined as observable and intentional “extreme” alterations to the body, is ...
  • Kong, Ying-Yee; Braida, Louis D. (American Speech-Language-Hearing Association, 2011-06)
    Purpose: Improved speech recognition in binaurally combined acoustic–electric stimulation (otherwise known as bimodal hearing) could arise when listeners integrate speech cues from the acoustic and electric hearing. The ...
  • Jarosz, Daniel F.; Walker, Gordon A.; Ung, W. Lloyd; Lancaster, Alex K.; Rotem, Assaf; Weitz, David A.; Bisson, Linda F.; Brown, Jessica Conrad; Lindquist, Susan; Datta, Manoshi Sen; Chang, Amelia N.; Newby, Gregory Arthur (Elsevier, 2014-08)
    In experimental science, organisms are usually studied in isolation, but in the wild they compete and cooperate in complex communities. We report a system for cross-kingdom communication by which bacteria heritably transform ...
  • McGuire, Abigail Manson; Pearson, Matthew D.; Neafsey, Daniel E.; Galagan, James E. (BioMed Central Ltd, 2008-03)
    Background: Variations in transcript splicing can reveal how eukaryotes recognize intronic splice sites. Retained introns (RIs) commonly appear when the intron definition (ID) mechanism of splice site recognition inconsistently ...
  • Jakubczak, Szymon Kazimierz; Katabi, Dina (Association for Computing Machinery (ACM), 2011-09)
    Today's mobile video suffers from two limitations: 1) it cannot reduce bandwidth consumption by leveraging wireless broadcast to multicast popular content to interested receivers, and 2) it lacks robustness to wireless ...
  • Lee, Kayi; Modiano, Eytan H. (Institute of Electrical and Electronics Engineers, 2009-06)
    In layered networks, a single failure at a lower layer may cause multiple failures in the upper layers. As a result, traditional schemes that protect against single failures may not be effective in cross-layer networks. ...
  • Vutukuru, Mythili; Balakrishnan, Hari; Jamieson, Kyle (Association for Computing Machinery (ACM), 2009)
    This paper presents SoftRate, a wireless bit rate adaptation protocol that is responsive to rapidly varying channel conditions. Unlike previous work that uses either frame receptions or signal-to-noise ratio (SNR) estimates ...
  • Vutukuru, Mythili; Balakrishnan, Hari; Jamieson, Kyle (Association for Computing Machinery, 2009-08)

  • Bonner, Daniel K.; Zhao, Xiaoyong; Buss, Hilda; Langer, Robert; Hammond, Paula T. (Elsevier, 2012-09)
    Crosslinked polyethylenimines (PEIs) have been frequently examined over the past decade since they can maintain the transfection efficiency of commercially available, 25 k branched PEI, but exhibit less cytotoxicity. The ...
  • Chen, Wenlan; Lin, Qian; Gullans, Michael; Lukin, Mikhail D.; Beck, Kristin Marie; Vuletic, Vladan (American Physical Society, 2014-09)
    Deterministic photon-photon interactions are a long-standing goal in optical science. Using an atomic ensemble inside a cavity, we demonstrate the mutual cross modulation of two continuous light beams at the level of ...
  • Ahn, Sung-Min; Beach, Geoffrey Stephen (American Institute of Physics, 2013-04)
    Interfacial magnetic anisotropy in Ta/Co[subscript x]Fe[subscript 100-x] (CoFe)/MgO films for alloy compositions spanning pure Co to pure Fe has been studied in order to investigate the role of chemical composition in the ...
  • Holtzman, Ran; Juanes, Ruben (American Physical Society, 2010-10)
    We investigate the displacement of one fluid by another in a deformable medium with pore-scale disorder. We develop a model that captures the dynamic pressure redistribution at the invasion front and the feedback between ...
  • von Krogh, Georg; von Hippel, Eric A. (Institute for Operations Research and the Management Sciences (INFORMS), 2015-12)
    Problem-solving research and formal problem-solving practice begin with the assumption that a problem has been identified or formulated for solving. The problem-solving process then involves a search for a satisfactory or ...
  • Spitz, Joshua B. (American Physical Society, 2014-04)
    The monoenergetic 236 MeV muon neutrino from charged kaon decay at rest (K[superscript +] → μ[superscript +]ν[subscript μ]) can be used to produce a novel set of cross section measurements. Applicable for short- and ...
