  • Bak, S. Peter G.; Barnkob, Mike Stein; Bai, Ailin; Higham, Eileen M.; Wittrup, Karl Dane; Chen, Jianzhu (American Association of Immunologists, 2012-07)
    A major obstacle to efficacious T cell-based cancer immunotherapy is the tolerizing-tumor microenvironment that rapidly inactivates tumor-infiltrating lymphocytes. In an autochthonous model of prostate cancer, we have ...
  • Garcia, Alexis; Muthupalani, Sureshkumar; Swennes, Alton G.; Fox, James G.; Shringi, Smriti; Lahmers, Kevin K.; Potter, Kathleen A.; Hovde, Carolyn J.; Call, Douglas R.; Besser, Thomas E. (American Society for Microbiology, 2011-10)
    Enterohemorrhagic Escherichia coli O157:H7 (EHEC O157) is an important cause of food and waterborne illness in the developed countries. Cattle are a reservoir host of EHEC O157 and a major source of human exposure through ...
  • Wan, Chen-Rei; Chung, Seok; Kamm, Roger Dale (Biomedical Engineering Society, 2011-06)
    The differentiation process of murine embryonic stem cells into cardiomyocytes was investigated with a compliant microfluidic platform which allows for versatile cell seeding arrangements, optical observation access, ...
  • Wang, Chun-Chin; Li, Feng-Chieh; Wu, Ruei-Jhih; Hovhannisyan, Vladimir A.; Lin, Wei-Chou; Lin, Sung-Jan; So, Peter T. C.; Dong, Chen-Yuan (Society of Photo-Optical Instrumentation Engineers, 2009-08)
    We utilize multiphoton microscopy for the label-free diagnosis of noncancerous, lung adenocarcinoma (LAC), and lung squamous cell carcinoma (SCC) tissues from humans. Our results show that the combination of second-harmonic ...
  • Gomez-Ceballos, Guillelmo; Goncharov, Maxim; Paus, Christoph M. E. (American Physical Society, 2012-08)
    We report on a study of diffractive dijet production in p̅p collisions at √s=1.96  TeV using the CDF II detector at the Fermilab Tevatron p̅p collider. A data sample from 310  pb[superscript -1] of integrated luminosity ...
  • Bauer, Gerry P.; Gomez-Ceballos, Guillelmo; Goncharov, Maxim; Makhoul, Khaldoun; Paus, Christoph M. E. (American Physical Society, 2010-12)
    We report on a measurement of the fraction of events with a W or Z boson which are produced diffractively in p̅ p collisions at √s=1.96  [square root of s = 1.96] TeV, using data from 0.6  fb-1 [fb superscript -1] of ...
  • Biesheuvel, P. M.; Fu, Yeging; Bazant, Martin Z. (American Physical Society, 2011-06)
    Porous electrodes instead of flat electrodes are widely used in electrochemical systems to boost storage capacities for ions and electrons, to improve the transport of mass and charge, and to enhance reaction rates. Existing ...
  • Biesheuvel, P. M.; Franco, Alejandro A.; Bazant, Martin Z. (Electrochemical Society, 2008-12)
    It is commonly assumed that electrolyte membranes in fuel cells are electrically neutral, except in unsteady situations, when the double-layer capacitance is heuristically included in equivalent circuit calculations. Indeed, ...
  • van Soestbergen, M.; Biesheuvel, P. M.; Bazant, Martin Z. (American Physical Society, 2010-02)
    We present theoretical models for the time-dependent voltage of an electrochemical cell in response to a current step, including effects of diffuse charge (or “space charge”) near the electrodes on Faradaic reaction kinetics. ...
  • Kirmani, Ahmed; Jeelani, Haris; Goyal, Vivek K. (Institute of Electrical and Electronics Engineers (IEEE), 2011-10)
    Conventional imaging uses steady-state illumination and light sensing with focusing optics; variations of the light field with time are not exploited. We develop a signal processing framework for estimating the reflectance ...
  • Kirmani, Ahmed; Jeelani, Haris; Montazerhodjat, Vahid; Goyal, Vivek K. (Society of Photo-optical Instrumentation Engineers, 2011-08)
    Conventional imaging uses steady-state illumination and light sensing with focusing optics; variations of the light field with time are not exploited. We develop a signal processing framework for estimating the reflectance ...
  • Hasinoff, Samuel W.; Levin, Anat; Goode, Philip R.; Freeman, William T. (Institute of Electrical and Electronics Engineers (IEEE), 2011-11)
    Diffuse objects generally tell us little about the surrounding lighting, since the radiance they reflect blurs together incident lighting from many directions. In this paper we discuss how occlusion geometry can help invert ...
  • Choi, J.; Crowdy, D.; Bazant, Martin Z. (Institute of Physics, 2010-09)
    We develop a general theory of transport-limited aggregation phenomena occurring on curved surfaces, based on stochastic iterated conformal maps and conformal projections to the complex plane. To illustrate the theory, we ...
  • Tzafriri, A. R.; Levin, A. D.; Edelman, Elazer R. (Wiley Blackwell, 2009-03)
    Background:  Local drug delivery has transformed medicine, yet it remains unclear how drug efficacy depends on physicochemical properties and delivery kinetics. Most therapies seek to prolong release, yet recent studies ...
  • Kindler, Kolja; Khalili, Arzhang; Stocker, Roman (National Academy of Sciences (U.S.), 2010-12)
    Downward carbon flux in the ocean is largely governed by particle settling. Most marine particles settle at low Reynolds numbers and are highly porous, yet the fluid dynamics of this regime have remained unexplored. We ...
  • Wedeen, Van J.; Sosnovik, David; Reese, Timothy G.; Dai, Guangping; Wang, Ruopeng (BioMed Central, 2009-11)
    Histological studies have shown that the myocardium consists of an array of crossing helical fiber tracts. Changes in myocardial fiber architecture occur in ischemic heart disease and heart failure, and can be imaged ...
  • Lizana, L.; Ambjornsson, T. (American Physical Society, 2009-11)
    We solve a nonequilibrium statistical-mechanics problem exactly, namely, the single-file dynamics of N hard-core interacting particles (the particles cannot pass each other) of size Δ diffusing in a one-dimensional system ...
  • Acemoglu, Daron; Ozdaglar, Asuman E.; Yildiz, Ercan (Institute of Electrical and Electronics Engineers (IEEE), 2011-12)
    While social networks do affect diffusion of innovations, the exact nature of these effects are far from clear, and, in many cases, there exist conflicting hypotheses among researchers. In this paper, we focus on the linear ...
  • Acemoglu, Daron; Ozdaglar, Asuman E.; Scaglione, Anna; Yildez, Mehmet Ercan (2011-05)
    In this paper, we are interested in modeling diffusion of innovations on social networks. We focus on a scenario where innovation emerges at a small number of nodes in the society, and each individual needs certain ...
  • Silbey, Robert J.; Barkai, E. (American Physical Society, 2010-04)
    We study the diffusion of tagged hard-core interacting Brownian point particles under the influence of an external force field in one dimension. Using the Jepsen line we map this many-particle problem onto a single particle ...
