  • Mercier, Patrick Philip; Daly, Denis C.; Chandrakasan, Anantha P. (Institute of Electrical and Electronics Engineers, 2009-05)
    This paper presents an all-digital, non-coherent, pulsed-UWB transmitter. By exploiting relaxed center frequency tolerances in non-coherent wideband communication, the transmitter synthesizes UWB pulses from an energy-efficient, ...
  • Kwong, Joyce; Chandrakasan, Anantha P. (Institute of Electrical and Electronics Engineers (IEEE), 2010-09)
    This paper presents an energy-efficient processing platform for wearable sensor nodes, designed to support diverse biological signals and algorithms. The platform features a 0.5V-1.0V 16b microcontroller, SRAM, and ...
  • Paradiso, Joseph A.; Aldrich, Matthew Henry; Zhao, Nan (SPIE, 2010-08)
    Motivated by opportunities in smart lighting, energy efficiency, and ubiquitous sensing, we present the design of polychromatic solid-state lighting controlled using a sensor network. We developed both a spectrally tunable ...
  • Kim, Byungsub; Stojanovic, Vladimir Marko (Institute of Electrical and Electronics Engineers (IEEE), 2010-06)
    This work describes the architecture and circuit implementation of a high-data-rate, energy-efficient equalized transceiver for high-loss dispersive channels, such as RC-limited on-chip interconnects or silicon-carrier ...
  • Feizi, Soheil; Angelopoulos, Georgios; Goyal, Vivek K.; Medard, Muriel (Institute of Electrical and Electronics Engineers (IEEE), 2012-01)
    Nowadays, since more and more battery-operated devices are involved in applications with continuous sensing, development of an efficient sampling mechanisms is an important issue for these applications. In this paper, we ...
  • Lee, Joo-Hyoung; Grossman, Jeffrey C. (American Physical Society, 2011-09)
    The electronic structure of graphene-graphane superlattices with armchair interfaces is investigated with first-principles density-functional theory. By separately varying the widths, we find that the energy gap Eg is ...
  • Shirgaonkar, Anup; MacIver, Malcolm A.; Patankar, Neelesh A. (Public Library of Science, 2010-05)
    While there is accumulating evidence for the importance of the metabolic cost of information in sensory systems, how these costs are traded-off with movement when sensing is closely linked to movement is poorly understood. ...
  • Balister, Paul; Bollobás, Béla; Anandkumar, Animashree; Willsky, Alan S. (Institute of Electrical and Electronics Engineers (IEEE), 2011-06)
    The problem of designing policies for in-network function computation with minimum energy consumption subject to a latency constraint is considered. The scaling behavior of the energy consumption under the latency constraint ...
  • Conforti, Matteo; De Angelis, Costantino; Akylas, Triantaphyllos R. (American Physical Society, 2011-04)
    We obtain solitary-wave solutions of a model describing light propagation in binary (linearly and nonlinearly) waveguide arrays. This model describes energy localization and transport in various physical settings, ranging ...
  • Sanchez, William R.; Sodini, Charles G.; Dawson, Joel L. (Institute of Electrical and Electronics Engineers (IEEE), 2010-09)
    We present the first known energy management IC to allow low-power systems, such as biomedical implants, to optimally use ultracapacitors instead of batteries as their chief energy storage elements. The IC, fabricated in ...
  • Roy, Arjun; Rumble, Stephen M.; Stutsman, Ryan; Levis, Philip; Mazieres, David; Zeldovich, Nickolai (Association for Computing Machinery, 2011-04)
    We argue that controlling energy allocation is an increasingly useful and important feature for operating systems, especially on mobile devices. We present two new low-level abstractions in the Cinder operating system, ...

  • Gutowski, Timothy G.; Gershwin, Stanley B.; Bounassisi, Tonio (Institute of Electrical and Electronics Engineers, 2010-07)
    During periods of growth, the energy payback performance of new energy generating technologies deviates substantially from the usual static measures of energy return on investment (EROI), and time to breakeven (tB) for ...
  • Leitermann, Olivia; Kirtley, James L., Jr. (Institute of Electrical and Electronics Engineers (IEEE), 2010-11)
    Certain energy storage technologies are well-suited to the high-frequency, high-cycling operation which is required in provision of load frequency control (LFC). To limit the total stored energy capacity required while ...
  • Pardal, Miguel L.; Harrison, Mark; Marques, Jose Alves; Sarma, Sanjay Emani (Institute of Electrical and Electronics Engineers (IEEE), 2012-11)
    Radio Frequency Identification (RFID) technology allows automatic data capture from tagged objects moving in a supply chain. This data can be very useful if it is used to answer traceability queries, however it is distributed ...
  • Jay, Steven M.; Kurtagic, Elma; Alvarez, Luis M.; De Picciotto, Seymour; Sanchez Palacios, Edgar I.; Hawkins, Jessica F.; Prince, Robin N.; Guerrero, Yadir; Treasure, Carolyn L.; Lee, Richard T.; Griffith, Linda G. (American Society for Biochemistry and Molecular Biology (ASBMB), 2011-05)
    The ErbB receptor family is dysregulated in many cancers, and its therapeutic manipulation by targeted antibodies and kinase inhibitors has resulted in effective chemotherapies. However, many malignancies remain refractory ...
  • Jay, Steven M.; Murthy, Ashwin C.; Hawkins, Jessica F.; Wortzel, Joshua R.; Steinhauser, Matthew L.; Alvarez, Luis M.; Gannon, Joseph; Macrae, Calum A.; Griffith, Linda G.; Lee, Richard T. (American Heart Association, 2013-06)
    Background—Doxorubicin (DOXO) is an effective anthracycline chemotherapeutic, but its use is limited by cumulative dose-dependent cardiotoxicity. Neuregulin-1β is an ErbB receptor family ligand that is effective against ...
