  • Bahr, Alexander; Leonard, John Joseph; Fallon, Maurice Francis (Sage Publications, 2009-06)
    This paper describes an algorithm for distributed acoustic navigation for Autonomous Underwater Vehicles (AUVs). Whereas typical AUV navigation systems utilize pre-calibrated arrays of static transponders, our work seeks ...
  • Wymeersch, Henk; Lien, Jaime; Win, Moe Z. (Institute of Electrical and Electronics Engineers, 2009-03)
    Location-aware technologies will revolutionize many aspects of commercial, public service, and military sectors, and are expected to spawn numerous unforeseen applications. A new era of highly accurate ubiquitous ...
  • Papadopoulos, Georgios; Fallon, Maurice Francis; Leonard, John Joseph (Institute of Electrical and Electronics Engineers (IEEE), 2013-05-15)
    This paper investigates the problem of cooperative navigation of autonomous marine vehicles using range-only acoustic measurements. We consider the use of a single maneuvering autonomous surface vehicle (ASV) to aid the ...
  • Garone, Emanuele; Naldi, Roberto; Casavola, Alessandro; Frazzoli, Emilio (Institute of Electrical and Electronics Engineers, 2011-02)
    In this work we focus on mission planning problems in scenarios in which a carrier vehicle, typically slow but with virtually infinite range, and a carried vehicle, which on the contrary is typically fast but has a shorter ...
  • Park, Ji-Ho; von Maltzahn, Geoffrey; Ong, Luvena L.; Centrone, Andrea; Hatton, T. Alan; Ruoslahti, Erkki; Bhatia, Sangeeta N.; Sailor, Michael J. (Wiley Blackwell, 2009-11)
    A cooperative nanosystem consisting of two distinct nanomaterials works in vivo to detect tumor tissues and deliver drugs to the site. Gold nanorods (GNRs) localize to the tumor region, where they report their location and ...

    The coordination of metabolic processes to allow increased nutrient uptake and utilization for macromolecular synthesis is central for cell growth. Although studies of bulk cell populations have revealed important metabolic ...
  • Zhang, Jingdi; Tan, Xuelian; Liu, Mengkun; Post, K. W.; Jin, Feng; Basov, D. N.; Wu, Wenbin; Averitt, R. D.; Teitelbaum, Samuel Welch; Nelson, Keith Adam (Nature Publishing Group, 2016-07)
    A major challenge in condensed-matter physics is active control of quantum phases. Dynamic control with pulsed electromagnetic fields can overcome energetic barriers, enabling access to transient or metastable states that ...
  • Chung, Soon-Jo; Slotine, Jean-Jacques E. (Institute of Electrical and Electronics Engineers, 2007-12)
    This article presents a simple synchronization framework that can be directly applied to cooperative control of multi-agent systems and oscillation synchronization in robotic manipulation and teleoperation. A dynamical ...
  • Metlitski, Max A.; Mross, David Fabian; Sachdev, Subir; Todadri, Senthil (American Physical Society, 2015-03)
    States of matter with a sharp Fermi surface but no well-defined Landau quasiparticles arise in a number of physical systems. Examples include (i) quantum critical points associated with the onset of order in metals; (ii) ...
  • Sternad, Dagmar; Park, Se-Woong; Muller, Hermann; Hogan, Neville (Public Library of Science, 2010-04)
    Analysis of motor performance variability in tasks with redundancy affords insight about synergies underlying central nervous system (CNS) control. Preferential distribution of variability in ways that minimally affect ...
  • Iosefson, Ohad; Nager, Andrew Ross; Baker, Tania; Sauer, Robert T (Nature Publishing Group, 2015-01)
    Hexameric ATP-dependent proteases and protein remodeling machines use conserved loops that line the axial pore to apply force to substrates during the mechanical processes of protein unfolding and translocation. Whether ...
  • Bachrach, Abraham Galton; Garamifard, Alborz; Gurdan, Daniel; He, Ruijie; Prentice, Samuel James; Stumpf, Jan; Roy, Nicholas (Springer Berlin / Heidleberg, 2009-01)
    The MAV ’08 competition in Agra, India focused on the problem of using air and ground vehicles to locate and rescue hostages being held in a remote building. Executing this mission required addressing a number of technical ...
  • Nichols, Joy S.; Corcoran, M. F.; Waldron, W.; Pollock, A. M. T.; Moffat, A. F. J.; Lauer, Jennifer L.; Shenar, T.; Russell, C. M. P.; Richardson, N. D.; Pablo, H.; Evans, N. R.; Hamaguchi, K.; Gull, T.; Hamann, W.-R.; Oskinova, Lidia M.; Ignace, R.; Hoffman, Jennifer L.; Hole, K. T.; Lomax, J. R.; Huenemoerder, David P.; Naze, Y. (IOP Publishing, 2015-08)
    We present time-resolved and phase-resolved variability studies of an extensive X-ray high-resolution spectral data set of the δ Ori Aa binary system. The four observations, obtained with Chandra ACIS HETGS, have a total ...
