    • Flexible timing by temporal scaling of cortical responses 

      Wang, Jing; Narain, Devika; Hosseini, Eghbal A.; Jazayeri, Mehrdad (Springer Nature, 2017-12)
      Musicians can perform at different tempos, speakers can control the cadence of their speech, and children can flexibly vary their temporal expectations of events. To understand the neural basis of such flexibility, we ...
    • Flexible Water Hose Failures: A Case Study and General Design Considerations 

      Taylor, Richard; Eagar, Thomas W. (Springer-Verlag, 2016-03)
      Flexible water hoses (or flexible hose connectors) have become commonplace in recent years and provide a low-cost and convenient alternative to rigid pipe. Unfortunately, inadequate designs, particularly with regard to the ...
    • Flexible, Wide-Area Storage for Distributed Systems with WheelFS 

      Stribling, Jeremy; Sovran, Yair; Zhang, Irene; Pretzer, Xavid F.; Li, Jinyang; e.a. (USENIX Association, 2009-04)
      WheelFS is a wide-area distributed storage system intended to help multi-site applications share data and gain fault tolerance. WheelFS takes the form of a distributed file system with a familiar POSIX interface. Its design ...
    • Flexpad: highly flexible bending interactions for projected handheld displays 

      Jordt, Andreas; Maes, Patricia; Steimle, Jurgen (Association for Computing Machinery (ACM), 2013-04)
      Flexpad is an interactive system that combines a depth camera and a projector to transform sheets of plain paper or foam into flexible, highly deformable, and spatially aware handheld displays. We present a novel approach ...
    • Flight calibration of the Suzaku XIS using the charge injection technique

      The X-ray Imaging Spectrometer (XIS) on board the Suzaku satellite is an X-ray CCD camera system that has features of a low background, high quantum efficiency, and good energy resolution in the 0.2 - 12 keV band. Because ...
    • Flight of a heavy particle nonlinearly coupled to a quantum bath 

      Maghrebi, Mohammad F.; Kardar, Mehran; Kruger, Matthias (American Physical Society, 2016-01)
      Fluctuation and dissipation are byproducts of coupling to the “environment.” The Caldeira-Leggett model, a successful paradigm of quantum Brownian motion, views the environment as a collection of harmonic oscillators ...
    • Flipping photons backward: reversed Cherenkov radiation 

      Chen, Hongsheng; Chen, Min (Elsevier B.V., 2011-01)
      Charged particles moving faster than light in a medium produce Cherenkov radiation. In traditional, positive index-of-refraction materials this radiation travels forward. Metamaterials, with negative indices of refraction, ...
