    We outline a facile fabrication technique for the realization of free-standing Al[subscript x]Ga[subscript 1−x]As heterostructures of arbitrary aluminum content. Utilizing xenon difluoride (XeF[subscript 2]) we rapidly and ...
  • Forward, Keith M.; Rutledge, Gregory C. (Elsevier, 2012-02)
    Electrostatic jetting from a free liquid surface offers an alternative to conventional electrospinning in which jets are emitted from spinnerets. In this work we analyze a system in which a wire electrode is swept (in a ...
  • de Macedo Rodrigues, Katyucia; Ben-Avi, Emma; Sliva, Danielle D.; Choe, Myong-sun; Drottar, Marie; Wang, Ruopeng; Fischl, Bruce; Grant, P. Ellen; Zollei, Lilla (Frontiers Research Foundation, 2015-02)
    We present a detailed description of a set of FreeSurfer compatible segmentation guidelines tailored to infant MRI scans, and a unique data set of manually segmented acquisitions, with subjects nearly evenly distributed ...

    We present measurements of three-dimensional correlation functions of like-sign, low-transverse-momentum kaon pairs from √s[subscript NN] = 200 GeV Au + Au collisions. A Cartesian surface-spherical harmonic decomposition ...
  • Smith, Cameron; Heyne, Steffen; Richter, Andreas S.; Will, Sebastian; Backofen, Rolf (Oxford University Press, 2010-05)
    The Freiburg RNA tools web server integrates three tools for the advanced analysis of RNA in a common web-based user interface. The tools IntaRNA, ExpaRNA and LocARNA support the prediction of RNA–RNA interaction, exact ...
  • Ferng, Jennifer H. (MIT Press, 2010-04)
    Artist and activist Jean-Jacques Lebel, who had imported beat poetry into France from the United States, once invited Gilles Deleuze and Felix Guattari to a 1975 concert held in Massachusetts, where the two had ...
  • Chilton, Lydia B.; Cordeiro, Felicia; Landay, James A.; Weld, Daniel S.; Dow, Steven P.; Miller, Robert C.; Zhang, Haoqi; Kim, Ju Ho; Andre, Paul (Association for Computing Machinery (ACM), 2014-04)
    Organizing conference sessions around themes improves the experience for attendees. However, the session creation process can be difficult and time-consuming due to the amount of expertise and effort required to consider ...
  • Egan, Kevin; Tseng, Yu-Ting; Holzschuch, Nicolas; Durand, Fredo; Ramamoorthi, Ravi (Association for Computing Machinery (ACM), 2009-08)
    Motion blur is crucial for high-quality rendering, but is also very expensive. Our first contribution is a frequency analysis of motion-blurred scenes, including moving objects, specular reflections, and shadows. We show ...
  • Ren, Y.; Hayton, D. J.; Hovenier, J. N.; Cui, M.; Gao, J. R.; Klapwijk, T. M.; Shi, S. C.; Kao, Tsung-Yu; Hu, Q.; Reno, J. L. (American Institute of Physics, 2012-09)
    We demonstrate an experimental scheme to simultaneously stabilize the frequency and amplitude of a 3.5 THz third-order distributed feedback quantum cascade laser as a local oscillator. The frequency stabilization has been ...
  • Rahul, Hariharan Shankar; Edalat, Farinaz; Katabi, Dina; Sodini, Charles G. (Association for Computing Machinery (ACM), 2009-09)
    There has been burgeoning interest in wireless technologies that can use wider frequency spectrum. Technology advances, such as 802.11n and ultra-wideband (UWB), are pushing toward wider frequency bands. The analog-to-digital ...
  • Perreault, David J.; Selders, Robert L.; Kassakian, John G. (Institute of Electrical and Electronics Engineers (IEEE), 1998-07)
    A new current-sharing technique for paralleled power converters, which is based on frequency encoding of the current-sharing information, is introduced. The approach has significant advantages over existing methods, including ...
  • Tsai, Tsung-Han; Zhou, Chao; Adler, Desmond C.; Fujimoto, James G. (Optical Society of America, 2009-11)
    We demonstrate a frequency comb (FC) swept laser and a frequency comb Fourier domain mode locked (FC-FDML) laser for applications in optical coherence tomography (OCT). The fiber-based FC swept lasers operate at a sweep ...
