  • Regnault, N.; Todadri, Senthil (American Physical Society, 2013-10)
    In two dimensions strongly interacting bosons in a magnetic field can form an integer quantum Hall state. This state has a bulk gap, no fractional charges or topological order in the bulk, but nevertheless quantized Hall ...
  • Safavi-Naini, Arghavan; Rabl, P.; Weck, P. F.; Sadeghpour, H. R. (American Physical Society, 2011-08)
    Motional heating of ions in microfabricated traps is one of the open challenges hindering experimental realizations of large-scale quantum processing devices. Recently, a series of measurements of the heating rates in ...
  • Gerber, U.; Hofmann, C. P.; Kampfer, Florian; Wiese, U. J. (American Physical Society, 2010-02)
    We consider a microscopic model for a doped quantum ferromagnet as a test case for the systematic low-energy effective field theory for magnons and holes, which is constructed in complete analogy to the case of quantum ...
  • Iusan, Diana; Kabir, Mohammad Mukul; Granas, Oscar; Eriksson, Olle; Sanyal, Biplab (American Physical Society, 2009-03)
    Density functional theory was applied to study the chemical and magnetic interactions between Co atoms doped in ZnO. It was found that the Co impurities tend to form nanoclusters and the interactions between these atoms ...
  • Fitzgerald, Eugene A.; Iutzi, Ryan Michael (American Institute of Physics (AIP), 2014-06)
    InAs/GaSb and similar materials systems have generated great interest as a heterojunction for tunnel field effect transistors (TFETs) due to favorable band alignment. However, little is currently understood about how such ...
  • Cho, Woo-Kyung; Ankrum, James Allen; Guo, Dagang; Chester, Shawn A.; Yang, Seung Yun; Kashyap, Anurag; Campbell, Georgina A.; Wood, Robert J.; Rijal, Ram K.; Karnik, Rohit N.; Langer, Robert; Karp, Jeffrey Michael (National Academy of Sciences (U.S.), 2012-12)
    North American porcupines are well known for their specialized hairs, or quills that feature microscopic backward-facing deployable barbs that are used in self-defense. Herein we show that the natural quill’s geometry ...
  • Johnson, Steven G.; Joannopoulos, John D.; McCauley, Alexander Patrick; Rodriguez, Alejandro W.; Reid, M. T. Homer; Zhao, Rongkuo; Zhou, Jiangfeng; Rossa, F. S. S.; Dalvit, D. A. R.; Soukoulis, Costas M. (American Physical Society, 2010-10)
    We examine a recent prediction for the chirality dependence of the Casimir force in chiral metamaterials by numerical computation of the forces between the exact microstructures, rather than homogeneous approximations. ...
  • Singh, Karuna; Tsai, Li-Huei (Elsevier, 2010-01)
    The microtubule network is crucial for the developing nervous system and mutations in tubulin-encoding genes disrupt neuronal migration. In this issue, Tischfield et al. (2010) report that mutations in the neuronal TUBB3 ...
  • Welburn, Julie P. I.; Cheeseman, Iain McPherson (American Society for Cell Biology, 2012-10)
    Microtubule dynamics are essential throughout mitosis to ensure correct chromosome segregation. Microtubule depolymerization is controlled in part by microtubule depolymerases, including the kinesin-13 family of proteins. ...
  • Hohnloser, Stefan H.; Cohen, Richard J. (Elsevier B.V., 2012-10)
    Gupta et al1 present a meta-analysis and conclude that microvolt T-wave alternans testing (MTWA) does not modify risk of sudden cardiac death (SCD) sufficiently for clinical use. Their analysis involves a number of ...
  • Cohen, Richard J.; Hohnloser, Stefan H. (Oxford University Press, 2012-05)
    Jackson et al. reported on a cohort of heart failure patients and concluded that microvolt T-wave alternans (MTWA) testing has limited utility in this population. Of note, this assessment was made in the complete absence ...
  • Drewsen, M; Shi, Molu; Herskind, Peter F.; Chuang, Isaac L. (IOP Publishing, 2013-11)
    A general method for rotational microwave spectroscopy and control of polar molecular ions via direct microwave addressing is considered. Our method makes use of spatially varying ac Stark shifts, induced by far off-resonant, ...
  • Khademhosseini, Ali; Hwang, Yu-Shik; Chung, Bong Geun; Moeller, Hannes-Christian; Ortmann, Daniel; Hattori, Nobuaki (National Academy of Sciences (U.S.), 2009-09)
    Recently, various approaches for controlling the embryonic stem (ES) cell microenvironment have been developed for regulating cellular fate decisions. It has been reported that the lineage specific differentiation could ...
  • Ozaydin-Ince, Gozde; Dubach, J. Matthew; Gleason, Karen K.; Clark, Heather A. (National Academy of Sciences, 2011-02)
    There have been a variety of nanoparticles created for in vivo uses ranging from gene and drug delivery to tumor imaging and physiological monitoring. The use of nanoparticles to measure physiological conditions while being ...
  • Huang, E-Wen; Qiao, Junwei; Winiarski, Bartlomiej; Lee, Wen-Jay; Scheel, Mario; Chuang, Chih-Pin; Liaw, Peter K.; Lo, Yu-Chieh; Zhang, Yong; Di Michiel, Marco (Nature Publishing Group, 2014-03)
    In-situ synchrotron x-ray experiments have been used to follow the evolution of the diffraction peaks for crystalline dendrites embedded in a bulk metallic glass matrix subjected to a compressive loading-unloading cycle. ...
  • Plovanich, Molly; Bogorad, Roman; Sancak, Yasemin; Kamer, Kimberli J.; Strittmatter, Laura; Li, Andrew A.; Girgis, Hany S.; Kuchimanchi, Satya; Groot, Jack De; Speciner, Lauren; Taneja, Nathan; OShea, Jonathan; Koteliansky, Victor; Mootha, Vamsi K. (Public Library of Science, 2013-02)
    Mitochondrial calcium uptake is present in nearly all vertebrate tissues and is believed to be critical in shaping calcium signaling, regulating ATP synthesis and controlling cell death. Calcium uptake occurs through a ...
  • Kunzi, Fabrice; Hansman Jr, Robert J (American Institute of Aeronautics and Astronautics, 2011-09)
    Automatic Dependent Surveillance - Broadcast (ADS-B) will be the basis of the future surveillance system in the US as well as many other countries. One way to create incentives for users to equip with the required ADS-B ...
  • Berggren, Karl K.; Hu, Xiaolong; Marsili, Francesco; Najafi, Faraz (Institute of Electrical and Electronics Engineers (IEEE), 2010-07)
    We present some major challenges of mid-infrared superconducting nanowire single-photon detector technology and our device design with nano-antenna integration to address these challenges.
  • Tang, Brian Hong-An; Emanuel, Kerry Andrew (American Meteorological Society, 2010-06)
    Midlevel ventilation, or the flux of low-entropy air into the inner core of a tropical cyclone (TC), is a hypothesized mechanism by which environmental vertical wind shear can constrain a tropical cyclone’s intensity. An ...
  • Chang, Chieh; Adler, Carolyn E.; Krause, Matthias; Clark, Scott G.; Tessier-Lavigne, Marc; Bargmann, Cornelia I.; Gertler, Frank (Elsevier, 2006-04)
    Background: The cytoplasmic C. elegans protein MIG-10 affects cell migrations and is related to mammalian proteins that bind phospholipids and Ena/VASP actin regulators. In cultured cells, mammalian MIG-10 promotes ...
