  • Mandal, Soumyajit; Sarpeshkar, Rahul (Institute of Electrical and Electronics Engineers (IEEE), 2010-08)
    We describe a novel wireless receiver architecture that is a broadband generalization of narrowband heterodyning systems commonly used in radio. It can be constructed with cochlea-like traveling-wave structures. We show ...
  • Bharadwaj, Hari M.; Verhulst, Sarah; Liberman, M. Charles; Shinn-Cunningham, Barbara G.; Shaheen, Luke Abraham (Frontiers Research Foundation, 2014-02)
    Many listeners with hearing thresholds within the clinically normal range nonetheless complain of difficulty hearing in everyday settings and understanding speech in noise. Converging evidence from human and animal studies ...
  • Grodzinsky, Alan J.; Lee, J. H.; Fitzgerald, J. B.; DiMicco, M. A.; Cheng, D. M.; Flannery, C. R.; Sandy, J. D.; Plaas, A. H. (Elsevier Ltd., 2009-09)
    We studied changes in chondrocyte gene expression, aggrecan degradation, and aggrecanase production and activity in normal and mechanically injured cartilage co-cultured with joint capsule tissue. Chondrocyte expression ...
  • Miller, Robert C.; Han, Sangmok; Wallace, David Robert (Institute of Electrical and Electronics Engineers, 2010-03)
    Abbreviation Completion is a novel technique to improve the efficiency of code-writing by supporting code completion of multiple keywords based on non-predefined abbreviated input - a different approach from conventional ...
  • Vierinen, Juha; Chau, Jorge L.; Pfeffer, Nico; Clahsen, Matthias; Stober, Gunter (Copernicus GmbH, 2016-03)
    The concept of a coded continuous wave specular meteor radar (SMR) is described. The radar uses a continuously transmitted pseudorandom phase-modulated waveform, which has several advantages compared to conventional pulsed ...
  • Cadambe, Viveck R.; Lynch, Nancy Ann; Medard, Muriel; Musial, Peter (Institute of Electrical and Electronics Engineers (IEEE), 2014-08)
    This paper considers the communication and storage costs of emulating atomic (linearizable) multi-writer multi-reader shared memory in distributed message-passing systems. The paper contains two main contributions: (1) ...
  • Cadambe, Viveck R.; Medard, Muriel; Musial, Peter; Lynch, Nancy Ann (Institute of Electrical and Electronics Engineers (IEEE), 2014-08)

  • Veeraraghavan, Ashok; Reddy, Dikpal; Raskar, Ramesh (Institute of Electrical and Electronics Engineers, 2011-04)
    We show that, via temporal modulation, one can observe and capture a high-speed periodic video well beyond the abilities of a low-frame-rate camera. By strobing the exposure with unique sequences within the integration ...
  • Kadambi, Achuta; Whyte, Refael; Bhandari, Ayush; Streeter, Lee; Barsi, Christopher; Dorrington, Adrian; Raskar, Ramesh (Association for Computing Machinery, 2013-11)
    Time of flight cameras produce real-time range maps at a relatively low cost using continuous wave amplitude modulation and demodulation. However, they are geared to measure range (or phase) for a single reflected bounce ...
  • Ravindranath, Lenin; Thiagarajan, Arvind; Balakrishnan, Hari; Madden, Samuel R. (Association for Computing Machinery (ACM), 2012-02)
    A growing class of smartphone applications are tasking applications that run continuously, process data from sensors to determine the user's context (such as location) and activity, and optionally trigger certain actions ...
  • Kaler, Timothy; Lynch, John Patrick; Peng, Timothy; Sivalingam, Lenin Ravindranth; Thiagarajan, Arvind; Balakrishnan, Hari; Madden, Samuel R. (Association for Computing Machinery, 2010-01)
    Modern smartphones are equipped with a wide variety of sensors including GPS, WiFi and cellular radios capable of positioning, accelerometers, magnetic compasses and gyroscopes, light and proximity sensors, and cameras. ...
  • Soudbakhsh, Damoon; Phan, Linh T. X.; Sokolsky, Oleg; Lee, Insup; Annaswamy, Anuradha M. (Association for Computing Machinery, 2013)
    This paper examines a co-design of control and platform in the presence of dropped signals. In a cyber-physical system, due to increasing complexities such as the simultaneous control of several applications, limited ...
  • Forney, G. David, Jr. (Institute of Electrical and Electronics Engineers (IEEE), 2011-02)
    A conceptual framework involving partition functions of normal factor graphs is introduced, paralleling a similar recent development by Al-Bashabsheh and Mao. The partition functions of dual normal factor graphs are shown ...
  • Gluesing-Luerssen, Heide; Forney, G. David, Jr. (Institute of Electrical and Electronics Engineers (IEEE), 2012-09)
    This paper investigates properties of realizations of linear or group codes on general graphs that lead to local reducibility. Trimness and properness are dual properties of constraint codes. A linear or group realization ...
  • Goldman, Max; Miller, Robert C. (Elsevier, 2009-05)
    When faced with the need for documentation, examples, bug fixes, error descriptions, code snippets, workarounds, templates, patterns, or advice, software developers frequently turn to their web browser. Web resources both ...
  • Miranda, Eva; Guillemin, Victor W.; Pissarra Pires, Ana Rita (Springer-Verlag, 2011-12)
    In this short note we give a complete characterization of a certain class of compact corank one Poisson manifolds, those equipped with a closed one-form defining the symplectic foliation and a closed two-form extending the ...
  • Abbe, Emmanuel A.; Zheng, Lizhong (Institute of Electrical and Electronics Engineers, 2009-08)
    This paper shows that the capacity achieving input distribution for a fading Gaussian broadcast channel is not Gaussian in general. The construction of non-Gaussian distributions that strictly outperform Gaussian ones, for ...
  • Medard, Muriel; Ozdaglar, Asuman E.; Chen, Wei; Traskov, Danail; Heindlmaier, Michael; Meyn, Sean P. (Springer ; Operations Research Society of America, 2009-12)
    The purpose of this paper is to survey techniques for constructing effective policies for controlling complex networks, and to extend these techniques to capture special features of wireless communication networks under ...
  • Delgutte, Bertrand; Chung, Yoojin; Hancock, Kenneth E.; Nam, Sung-Il (Society for Neuroscience, 2013-12)
    Cochlear implant (CI) listeners show limits at high frequencies in tasks involving temporal processing such as rate pitch and interaural time difference discrimination. Similar limits have been observed in neural responses ...
  • Merrikh, Houra; Machon, Cristina; Grainger, William H.; Grossman, Alan D.; Soultanas, Panos (Nature Publishing Group, 2011-02)
    Head-on encounters between the replication and transcription machineries on the lagging DNA strand can lead to replication fork arrest and genomic instability1, 2. To avoid head-on encounters, most genes, especially essential ...
