  • Aguirre, Aaron Dominic; Sawinski, Juergen; Huang, Shu-Wei; Zhou, Chao; Denk, Winfried; Fujimoto, James G. (Optical Society of America, 2010-02)
    Optical coherence microscopy (OCM) is a promising technique for high resolution cellular imaging in human tissues. An OCM system for high-speed en face cellular resolution imaging was developed at 1060 nm wavelength at ...
  • Albrecht, Simon H.; Winn, Joshua Nathan; Butler, R. Paul; Crane, Jeffrey D.; Shectman, Stephen A.; Thompso, Ian B.; Hirano, Teruyuki; Wittenmyer, Robert A. (IOP Publishing, 2011-12)
    We measure a tilt of 86° ± 6° between the sky projections of the rotation axis of the WASP-7 star and the orbital axis of its close-in giant planet. This measurement is based on observations of the Rossiter-McLaughlin (RM) ...
  • Tang, Evelyn May Yin; Mei, Jiawei; Wen, Xiao-Gang (American Physical Society, 2011-06)
    We show that a suitable combination of geometric frustration, ferromagnetism, and spin-orbit interactions can give rise to nearly flatbands with a large band gap and nonzero Chern number. Partial filling of the flatband ...
  • Wade, Aaron; Fedorov, Georgy; Smirnov, Dmitry; Williams, Benjamin S.; Kumar, Sushil; Hu, Qing; Reno, John L. (Institute of Electrical and Electronics Engineers (IEEE), 2009-08)
    We demonstrate magnetic field assisted, (sub)THz quantum cascade laser operating above 200 K. This is achieved through the application of strong magnetic fields which provide an additional lateral confinement in order to ...
  • Chan, Chun Wang Ivan; Hu, Qing; Qin, Qi; Kumar, Sushil; Reno, John L. (SPIE, 2011-02)
    We demonstrate a terahertz quantum-cascade laser (QCL) operating significantly above the temperature of hv/kB, which had so-far been been an empirical limitation for the maximum operating temperature of these devices. With ...
  • Iwasa, Yukikazu; Bascunan, Juan; Hahn, Seung-Yong; Tomita, Masaru; Yao, Weijun (Institute of Electrical and Electronics Engineers (IEEE), 2010-06)
    This paper describes the NMR/MRI magnets that are currently being developed at the MIT Francis Bitter Magnet Laboratory: 1) a 1.3 GHz NMR magnet; 2) a compact NMR magnet assembled from YBCO annuli; and 3) a persistent-mode, ...
  • Wang, Fa; Xiang, Yuan-Yuan; Wang, Da; Wang, Qiang-Hua; Lee, Dung-Hai (American Physical Society, 2012-10)
    In several recent experiments the superconducting gap of a single-unit-cell-thick FeSe film on SrTiO[subscript 3] substrate has been observed by scanning tunneling spectroscopy and angle-resolved photoemission spectroscopy. ...
  • Oberoi, Divya; Evarts, Eric R.; Rogers, Alan E. E. (Springer, 2009-10)
    We report very high temporal and spectral resolution interferometric observations of some unusual solar radio bursts near 1420 MHz. These bursts were observed on 13 September 2005, 22 minutes after the peak of a GOES ...
  • Sze, Vivienne; Chandrakasan, Anantha P. (Institute of Electrical and Electronics Engineers, 2009-11)
    Enabling parallel processing is becoming increasingly necessary for video decoding as performance requirements continue to rise due to growing resolution and frame rate demands. It is important to address known bottlenecks ...
  • Angelosanto, Jill; Brosnahan, Kathleen; Ross, Kenneth; Hahn, Cynthia; Russell, Kate; Drury, Linda; Norton, Stephanie; Nadler, Lee; Stegmaier, Kimberly; Haining, W. Nicholas (BioMed Central Ltd, 2008-08)
    Background: The differentiation of naive T and B cells into memory lymphocytes is essential for immunity to pathogens. Therapeutic manipulation of this cellular differentiation program could improve vaccine efficacy and ...
  • Pardo-Martin, Carlos; Chang, Tsung-Yao; Koo, Bryan Kyo; Gilleland, Cody Lee; Wasserman, Steven Charles; Yanik, Mehmet Fatih (Nature Publishing Group, 2010-07)
    We demonstrate a high-throughput platform for cellular-resolution in vivo chemical and genetic screens on zebrafish larvae. The system automatically loads zebrafish from reservoirs or multiwell plates, and positions and ...
  • Xu, Feng; Beyazoglu, Turker; Emre, Ahmet E.; Hefner, Evan; Manzur, Tariq; Demirci, Utkan; Moon, SangJun (Society of Photo-optical Instrumentation Engineers, 2010-04)
    Cell-based biosensors (CBBs) have important applications in biosecurity and rapid diagnostics. Current CBB technologies have challenges including cell immobilization on the sensors, high throughput fabrication and portability, ...
  • Kothapalli, Chandrasekhar R.; Van Veen, Ed; de Valence, Sarra; Chung, Seok; Zervantonakis, Ioannis; Gertler, Frank; Kamm, Roger Dale (Royal Society of Chemistry, 2010-11)
    Studying neurite guidance by diffusible or substrate bound gradients is challenging with current techniques. In this study, we present the design, fabrication and utility of a microfluidic device to study neurite guidance ...
  • Rohde, Christopher Benjamin; Gilleland, Cody Lee; Samara, Chrysanthi; Yanik, Mehmet Fatih (SPIE, 2010-02)
    Therapeutic treatment of spinal cord injuries, brain trauma, stroke, and neurodegenerative diseases will greatly benefit from the discovery of compounds that enhance neuronal regeneration following injury. We previously ...
  • Samara, Chrysanthi; Gilleland, Cody Lee; Zeng, Fei; Rohde, Christopher Benjamin; Yanik, Mehmet Fatih (Society of Photo-optical Instrumentation Engineers, 2009-02)
    In recent years, the advantages of using small invertebrate animals as model systems for human disease have become increasingly apparent and have resulted in three Nobel Prizes in medicine or chemistry during the last six ...
  • Cox, David D.; Pinto, Nicolas; Doukhan, David; DiCarlo, James (Public Library of Science, 2009-11)
    While many models of biological object recognition share a common set of ‘‘broad-stroke’’ properties, the performance of any one model depends strongly on the choice of parameters in a particular instantiation of that ...

  • Steinmeyer, Joseph Daly; Yanik, Mehmet Fatih (Public Library of Science, 2012-04)
    The complexity of neurons and neuronal circuits in brain tissue requires the genetic manipulation, labeling, and tracking of single cells. However, current methods for manipulating cells in brain tissue are limited to ...
