  • Herr, Keira Joann; Tsang, Ying-hung Nicole; Ong, Joanne Wei En; Li, Qiushi; Yap, Lai Lai; Yu, Weimiao; Yin, Hao; Dahlman, James E.; Chan, Yee Gek; Bay, Boon Huat; Singaraja, Roshni; Koteliansky, Victor; Viasnoff, Virgile; Thiery, Jean Paul; Bogorad, Roman; Anderson, Daniel Griffith (Nature Publishing Group, 2014-10)
    The liver is unique in its capacity to regenerate after injury, during which hepatocytes actively divide and establish cell-cell contacts through cell adhesion complexes. Here, we demonstrate that the loss of α-catenin, a ...
  • Wang, Da; Mazumdar, Arya; Wornell, Gregory W. (Institute of Electrical and Electronics Engineers (IEEE), 2014-06)
    We investigate the lossy compression of permutations by analyzing the trade-off between the size of a source code and the distortion with respect to Kendall tau distance, Spearman's footrule, Chebyshev distance and ℓ[subscript ...
  • Pathak, Parag; Sethuraman, Jay (Society for Economic Theory, 2010-06)
    This paper formally examines two competing methods of conducting a lottery in assigning students to schools, motivated by the design of the centralized high school student assignment system in New York City. The main ...
  • Malik, Wasim Q.; Liu, Yi; Zhang, Yangyang; Ji, Chunlin; Edwards, David J. (Institute of Electrical and Electronics Engineers, 2009-06)
    In this paper, a novel low-complexity antenna-selection algorithm based on a constrained adaptive Markov chain Monte Carlo (CAMCMC) optimization method is proposed to approach the maximum capacity or minimum bit error rate ...
  • Siah, Sin Cheng; Lee, Yun Seog; Segal, Yaron; Buonassisi, Tonio (American Institute of Physics (AIP), 2012-10)
    Forming low-resistivity contacts on cuprous oxide (Cu[subscript 2]O) is an essential step toward demonstrating its suitability as a candidate solar cell material. We measure the contact resistivity of three noble metals ...
  • Hoehl, Melanie Margarete; Bocholt, Eva Schulte; Karippai, Nobu; Zengerle, Roland; Steigert, Juergen; Slocum, Alexander H. (Chemical and Biological Microsystems Society, 2013-10)
    To ensure food, medical and environmental safety and quality, rapid, low-cost and easy-to-use detection methods are desirable. Here, the LabSystem is introduced for integrated, automated DNA purification and amplification. ...
  • Kannan, Pravein Govindan; Venkatagiri, Seshadri Padmanabha; Chan, Mun Choon; Ananda, Akhihebbal L.; Peh, Li-Shiuan (Association for Computing Machinery (ACM), 2012-11)
    With mobile devices becoming ubiquitous, collaborative applications have become increasingly pervasive. In these applications, there is a strong need to obtain a count of the number of mobile devices present in an area, ...
  • Sheng, Xing; Liu, Jifeng; Michel, Jurgen; Agarwal, Anuradha Murthy; Kimerling, Lionel C. (Institute of Electrical and Electronics Engineers, 2010-02)
    Light trapping has been an important issue for thin film silicon solar cells because of the low absorption coefficient in the near infrared range. In this paper, we present a photonic structure which combines anodic aluminum ...
  • Fletcher, Richard Ribon; Han, Jing (Institute of Electrical and Electronics Engineers, 2009-07)
    We present a differential front end design for improving the performance of short-range low-cost Doppler radars for vital sign detection with application to automotive driver safety systems, health monitoring, and security ...
  • Codd, Daniel S.; Carlson, Andrew T.; Rees, Jennifer; Slocum, Alexander H. (Elsevier, 2010-10)
    A low cost, high flux, large area solar simulator has been designed, built and characterized for the purpose of studying optical melting and light absorption behavior of molten salts. Seven 1500 W metal halide outdoor ...
  • Fucetola, Corey P.; Korre, Hasan; Berggren, Karl K. (American Vacuum Society (AVS), 2009-12)
    The authors report demonstration of a low-cost ( ∼ 1000 USD) interference lithography system based on a Lloyd’s mirror interferometer that is capable of ∼ 300 nm pitch patterning. The components include only a 405 nm GaN ...
  • Gong, Nan-Wei; Wang, Chiu-Yen; Paradiso, Joseph A.; Gong, Nan-wei (Institute of Electrical and Electronics Engineers (IEEE), 2012-10)
    We describe the concept of fabricating low-cost sensor tape for fine-grid environmental sensing based on roll-to-roll manufacturing processes. We experiment with constructing sensors and electronic connections with low-cost ...
  • Demirbas, Umit; Li, Duo; Birge, Jonathan R.; Sennaroglu, Alphan; Petrich, Gale S.; Kolodziejski, Leslie A.; Kaertner, Franz X.; Fujimoto, James G. (Optical Society of America, 2009-07)
    We present three Cr[superscript 3+]:Colquiriite lasers as low-cost alternatives to Ti:Sapphire laser technology. Single-mode laser diodes, which cost only $150 each, were used as pump sources. In cw operation, with ~520 ...
  • Bhattacharyya, Rahul; Floerkemeier, Christian; Sarma, Sanjay Emani (Institute of Electrical and Electronics Engineers, 2010-09)
    Radio-frequency identification (RFID) has been well established as an effective technology for track and trace applications. In this paper, we go beyond the ID in RFID, and discuss the potential for RFID tags to be used ...
  • Reich, Robert K.; Gregory, James A.; Young, Douglas J.; Loomis, Andrew H.; Clark, Harry R., Jr.; Burke, Barry E.; Westhoff, Richard C. (Society of Photo-optical Instrumentation Engineers, 2009-01)
    Dark current for back-illuminated (BI) charge-coupled-device (CCD) imagers at Lincoln Laboratory has historically been higher than for front-illuminated (FI) detectors. This is presumably due to high concentrations of ...
  • Zhou, Hongchao; Chandar, Venkat; Wornell, Gregory W. (Institute of Electrical and Electronics Engineers (IEEE), 2013-07)
    Secret key extraction, the task of extracting a secret key from shared information that is partially known by an eavesdropper, has important applications in cryptography. Motivated by the requirements of high-speed quantum ...
  • Ozsvath, Peter; Lipshitz, Robert; Thurston, Dylan P. (National Academy of Sciences (U.S.), 2011-04)
    Heegaard Floer theory is a kind of topological quantum field theory (TQFT), assigning graded groups to closed, connected, oriented 3-manifolds and group homomorphisms to smooth, oriented four-dimensional cobordisms. Bordered ...
  • Asif, Muhammad Tayyab; Mitrovic, Nikola; Garg, Lalit; Dauwels, Justin; Jaillet, Patrick (Institute of Electrical and Electronics Engineers (IEEE), 2013-05)
    Intelligent transport systems (ITS) require data with high spatial and temporal resolution for applications such as modeling, traffic management, prediction and route guidance. However, field data is usually quite sparse. ...
  • Rinnerbauer, Veronika; Senkevich, Jay; Joannopoulos, John D.; Soljacic, Marin; Celanovic, Ivan (American Vacuum Society (AVS), 2012-11)
    The authors study the use of thin ( ∼ 230 nm) tantalum (Ta) layers on silicon (Si) as a low emissivity (high reflectivity) coating for high-temperature Si devices. Such coatings are critical to reduce parasitic radiation ...
