  • Lo, Andrew W.; Khandani, Amir Ehsan (World Scientific, 2011-06)
    We establish a link between illiquidity and positive autocorrelation in asset returns among a sample of hedge funds, mutual funds, and various equity portfolios. For hedge funds, this link can be confirmed by comparing the ...
  • Silbey, Susan S.; Agrawal, Tanu (World Scientific, 2011-01)
    How do laws and regulations govern the activities of large, decentralized, and often geographically dispersed organizations? Under conditions of loose coupling, how does the organization coordinate action and know what it ...
  • Redaelli, F.; Santambrogio, Marco Domenico; Memik, S. Ogrenci (Hindawi Publishing, 2009-09)
    This work proposes an exact ILP formulation for the task scheduling problem on a 2D dynamically and partially reconfigurable architecture. Our approach takes physical constraints of the target device that is relevant for ...
  • Kamentsky, Lee; Liu, Zihan H; Riklin-Raviv, Tammy; Conery, Annie L; O'Rourke, Eyleen J; Sokolnicki, Katherine L; Visvikis, Orane; Ljosa, Vebjorn; Irazoqui, Javier E; Golland, Polina; Ruvkun, Gary; Ausubel, Frederick M; Carpenter, Anne E; Wahlby, Carolina (Nature Publishing Group, 2012-04)
    We present a toolbox for high-throughput screening of image-based Caenorhabditis elegans phenotypes. The image analysis algorithms measure morphological phenotypes in individual worms and are effective for a variety of ...
  • Bae, Soonmin; Cho, Peter L.; Durand, Fredo (The International Society for Optical Engineering, 2009-05)
    We extend recent automated computer vision algorithms to reconstruct the global three-dimensional structures for photos and videos shot at fixed points in outdoor city environments. Mosaics of digital stills and embedded ...
  • Lanman, Douglas; Mohan, Ankit; Hiura, Shinsaku; Raskar, Ramesh (Institute of Electrical and Electronics Engineers, 2010-08)
    We propose a novel camera setup in which both the lens and the sensor are perturbed during the exposure. We analyze the defocus effects produced by such a setup, and use it to demonstrate new methods for simulating a lens ...
  • Shenton, Martha E.; Balci, Serdar K.; Sabuncu, Mert R.; Golland, Polina (Institute of Electrical and Electronics Engineers, 2009-08)
    We present iCluster, a fast and efficient algorithm that clusters a set of images while co-registering them using a parameterized, nonlinear transformation model. The output of the algorithm is a small number of template ...
  • Khosla, Aditya; Xiao, Jianxiong; Isola, Phillip John; Torralba, Antonio; Oliva, Aude (Association for Computing Machinery, 2012)
    When glancing at a magazine, or browsing the Internet, we are continuously being exposed to photographs. However, not all images are equal in memory; some stitch to our minds, while others are forgotten. In this paper we ...
  • Kovac, Joseph; Gerardin, Ylaine; Voldman, Joel (Wiley Blackwell, 2012-11)
    Using photopatterned hydrogels and selective cell encapsulation, populations of adherent cells are examined using microscopy and sorted into viable sub-populations predicated on their imaged phenotypes. The inexpensive ...
  • Cho, Taeg Sang; Zitnick, C. Lawrence; Joshi, Neel; Kang, Sing Bing; Szeliski, Richard; Freeman, William T. (Institute of Electrical and Electronics Engineers (IEEE), 2011-08)
    The restoration of a blurry or noisy image is commonly performed with a MAP estimator, which maximizes a posterior probability to reconstruct a clean image from a degraded image. A MAP estimator, when used with a sparse ...
  • Masters, Barry R. (Society of Photo-optical Instrumentation Engineers, 2011-03)
    Imaging: A Laboratory Manual Rafael Yuste, Editor 952 pages; ISBN 978-087969-36-9, Cold Spring Harbor Laboratory Press,Woodbury, NewYork (2011), $165 paperback. Reviewed by Barry R. Masters, Visiting Scientist, ...
  • Zou, Peng; Ting, Alice Y. (American Chemical Society, 2010-12)
    Methods to probe receptor oligomerization are useful to understand the molecular mechanisms of receptor signaling. Here we report a fluorescence imaging method to determine receptor oligomerization state in living cells ...
  • Grulkowski, Ireneusz; Liu, Jonathan Jaoshin; Baumann, Bernhard; Potsaid, Benjamin M.; Lu, Chen David; Fujimoto, James G. (Photonics Society of Poland, 2011-12)
    We demonstrate application of high-speed swept source optical coherence tomography for vessel visualization in the anterior segment of the human eye. The human corneo-scleral junction and sclera was imaged in vivo. Imaging ...
  • Meriles, Carlos A.; Jiang, Liang; Goldstein, Garry; Hodges, Jonathan S.; Maze, Jeronimo; Lukin, Mikhail D.; Cappellaro, Paola (American Institute of Physics, 2010-09)
    Magnetic resonance imaging can characterize and discriminate among tissues using their diverse physical and biochemical properties. Unfortunately, submicrometer screening of biological specimens is presently not possible, ...
  • Tomat, Elisa; Lippard, Stephen J. (Elsevier Ltd., 2010-01)
    Trafficking and regulation of mobile zinc pools influence cellular functions and pathological conditions in multiple organs, including brain, pancreas, and prostate. The quest for a dynamic description of zinc distribution ...
  • Wise, W. D.; Chatterjee, Kamalesh; Boyer, Michael C.; Kondo, Takeshi; Takeuchi, T.; Ikuta, H.; Xu, Zhijun; Wen, Jinsheng; Gu, G. D.; Hudson, Eric (Nature Publishing Group, 2009-01)
    Particle–wave duality suggests we think of electrons as waves stretched across a sample, with wavevector k proportional to their momentum. Their arrangement in 'k-space', and in particular the shape of the Fermi surface, ...
  • Peier, P.; Merbold, H.; Pahinin, V.; Nelson, Keith Adam; Feurer, T. (Institute of Physics Publishing, 2010-01)
    We present space- and time-resolved simulations and measurements of single-cycle terahertz (THz) waves propagating through two-dimensional (2D) photonic crystal structures embedded in a slab waveguide. Specifically, we use ...
  • Cuneo, Kyle C.; Mito, Jeffrey K.; Javid, Melodi P.; Ferrer, Jorge M.; Kim, Yongbaek; Lee, W. David; Bawendi, Moungi G.; Brigman, Brian E.; Kirsch, David G. (Elsevier B.V., 2013-05)
    Purpose: Cathepsin-activated fluorescent probes can detect tumors in mice and in canine patients. We previously showed that these probes can detect microscopic residual sarcoma in the tumor bed of mice during gross total ...
  • Slavoff, Sarah A.; Liu, Daniel S.; Cohen, Justin D.; Ting, Alice Y. (American Chemical Society (ACS), 2011-11)
    We report a new method, Interaction-Dependent PRobe Incorporation Mediated by Enzymes, or ID-PRIME, for imaging protein–protein interactions (PPIs) inside living cells. ID-PRIME utilizes a mutant of Escherichia coli lipoic ...
  • Johannsson, Hordur; Kaess, Michael; Englot, Brendan J.; Hover, Franz S.; Johnson, Leonard M. (Institute of Electrical and Electronics Engineers (IEEE), 2010-10)
    In this paper we address the problem of drift-free navigation for underwater vehicles performing harbor surveillance and ship hull inspection. Maintaining accurate localization for the duration of a mission is important ...
