  • Balewski, Jan T.; Betancourt, Michael Joseph; Corliss, Ross Cameron; Hays-Wehle, J. P.; Leight, William Axel; Milner, Richard G.; Redwine, Robert P.; Seele, J.; Walker, M.; van Nieuwenhuizen, Gerrit Jan; Steadman, Stephen G.; Surrow, Bernd (American Physical Society, 2012-07)
    We present STAR measurements of azimuthal anisotropy by means of the two- and four-particle cumulants v[subscript 2] (v[subscript 2]{2} and v[subscript 2]{4}) for Au+Au and Cu+Cu collisions at center-of-mass energies ...
  • Angelopoulos, Georgios; Chandrakasan, Anantha P.; Medard, Muriel (Springer-Verlag, 2011-05)
    In the last few years, Network Coding (NC) has been shown to provide several advantages, both in theory and in practice. However, its applicability to battery-operated systems under strict power constraints has not been ...
  • Philips, Scott M.; Berisha, Visar; Spanias, Andreas (Institute of Electrical and Electronics Engineers, 2009-05)
    Dimensionality reduction algorithms have become an indispensable tool for working with high-dimensional data in classification. Linear discriminant analysis (LDA) is a popular analysis technique used to project high-dimensional ...
  • Salam, Gavin P.; Thaler, Jesse; Larkoski, Andrew James (Springer-Verlag, 2013-06)
    We show how generalized energy correlation functions can be used as a powerful probe of jet substructure. These correlation functions are based on the energies and pair-wise angles of particles within a jet, with (N + 1)-point ...
  • Roland, Christof E.; Roland, Gunther M. (American Physical Society, 2011-06)
    Kaons and protons carry large parts of two conserved quantities: strangeness and baryon number. It is argued that their correlation and thus also fluctuations are sensitive to conditions prevailing at the anticipated ...
  • Balewski, Jan T.; Corliss, Ross; Hays-Wehle, James Prewitt; Leight, William Axel; Stevens, Justin; van Nieuwenhuizen, Gerrit Jan; Walker, M. (American Physical Society, 2014-01)
    We report the beam energy (√s[subscript NN] = 7.7–200  GeV) and collision centrality dependence of the mean (M), standard deviation (σ), skewness (S), and kurtosis (κ) of the net-proton multiplicity distributions in Au + ...
  • Veres, Gabor; Roland, Christof E.; Roland, Gunther M. (American Physical Society, 2009-04)
    We present measurements of the energy dependence of event-by-event fluctuations in the K/pi and (p+p[over-bar])/pi multiplicity ratios in heavy-ion collisions at the CERN SPS. The particle ratio fluctuations were obtained ...
  • Veres, Gabor; Roland, Christof E.; Roland, Gunther M. (American Physical Society, 2009-04)
    Results are presented on event-by-event fluctuations of transverse momenta pT in central Pb[plus]Pb interactions at 20A, 30A, 40A, 80A, and 158A GeV. The analysis was performed for charged particles at forward center-of-mass ...
  • Sader, John E.; Burg, Thomas P.; Manalis, Scott R. (Cambridge University Press, 2010-03)
    The fluid–structure interaction of resonating microcantilevers immersed in fluid has been widely studied and is a cornerstone in nanomechanical sensor development. In many applications, fluid damping imposes severe limitations ...
  • Sader, John E.; Lee, Jungchul; Manalis, Scott R. (American Institute of Physics, 2010-12)
    Energy dissipation experienced by vibrating microcantilever beams immersed in fluid is strongly dependent on the mode of vibration, with quality factors typically increasing with mode number. Recently, we examined energy ...
  • Sader, John E.; Burg, Thomas P.; Lee, Jungchul; Manalis, Scott R. (American Physical Society, 2011-08)
    Dissipation of mechanical energy underlies the sensitivity of many nanomechanical devices, with environmental effects often having a significant effect. One case of practical relevance is the interaction of elastic beam ...
  • Song, Justin Chien Wen; Levitov, Leonid (American Physical Society, 2012-12)
    Coulomb coupling in graphene heterostructures results in vertical energy transfer between electrons in proximal layers. We show that, in the presence of correlated density inhomogeneity in the layers, vertical energy ...
  • Narayan, G. Prakash; Mistry, Karan Hemant; Sharqawy, Mostafa H.; Zubair, Syed M.; Lienhard, John H. (Global Digital Central, 2010)
    Simultaneous heat and mass exchange devices such as cooling towers, humidifiers and dehumidifiers are widely used in the power generation, desalination, air conditioning, and refrigeration industries. For design and rating ...
  • 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 ...

    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. ...
