    • Loop-Free Backpressure Routing Using Link-Reversal Algorithms 

      Rai, Anurag; Li, Chih-ping; Paschos, Georgios; Modiano, Eytan H. (Association for Computing Machinery (ACM), 2015-06)
      The backpressure routing policy is known to be a throughput optimal policy that supports any feasible traffic demand in data networks, but may have poor delay performance when packets traverse loops in the network. In this ...
    • Loop-free synthesis of finite state machines 

      Zeiger, Howard Paul (Massachusetts Institute of Technology, 1964)
    • Loop-fusion cohomology and transgression 

      Kottke, Chris; Melrose, Richard B (2015)
      ‘Loop-fusion cohomology’ is defined on the continuous loop space of a manifold in terms of Čech cochains satisfying two multiplicative conditions with respect to the fusion and figure-of-eight products on loops. The main ...
    • Loops in multicommodity flows 

      Gallager, Robert G.; Massachusetts Institute of Technology. Laboratory for Information and Decision Systems. (Laboratory for Information and Decision Systems, Massachusetts Institute of Technology, 1974)
    • Loops, sign structures, and emergent Fermi statistics in three-dimensional quantum dimer models 

      Ivanov, Vsevolod; Qi, Yang; Fu, Liang (American Physical Society, 2014-02)
      We introduce and study three-dimensional quantum dimer models with positive resonance terms. We demonstrate that their ground state wave functions exhibit a nonlocal sign structure that can be exactly formulated in terms ...
    • Loose Legendrians and the plastikstufe 

      Murphy, Emmy; Niederkrüger, Klaus; Plamenevskaya, Olga; Stipsicz, András I (Mathematical Sciences Publishers, 2013-07)
      We show that the presence of a plastikstufe induces a certain degree of flexibility in contact manifolds of dimension 2n+1>3. More precisely, we prove that every Legendrian knot whose complement contains a “nice” plastikstufe ...
    • LoPC-- modeling contention in parallel algorithms 

      Frank, Matthew I (Massachusetts Institute of Technology, 1998)

      Heinz, S.; Burton, M.; Braiding, C.; Brandt, W. N.; Jonker, P. G.; e.a. (IOP Publishing, 2015-06)
      Circinus X-1 exhibited a bright X-ray flare in late 2013. Follow-up observations with Chandra and XMM-Newton from 40 to 80 days after the flare reveal a bright X-ray light echo in the form of four well-defined rings with ...
    • Lorentz actuators for turbulence control and underwater acoustic communications 

      Sura, Daniel A (Massachusetts Institute of Technology, 2005)
      Lorentz actuator dynamics in a fluid are governed by the fundamental principles of electromagnetism and hydrodynamics and have several potential applications in the marine field. Two areas of interest where improvements ...
    • Lorentz force actuator and carbon fiber co-winding design, construction and characterization 

      Chen, Yi, S. B. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2008)
      Carbon fiber composites are materials that present many benefits to engineering applications, ranging from aerospace to medicine. This thesis provides background on carbon fiber properties and manufacturing techniques, and ...
    • Lorentz force and radiation pressure on a spherical cloak 

      Chen, Hongsheng; Zhang, Baile; Luo, Yu; Kemp, Brandon A.; Zhang, Jingjing; e.a. (American Physical Society, 2009-05)
      The mechanical behavior of a transformation based spherical cloak under wave illumination is derived. We show that the equatorial region of the cloak is subject to much higher stress than the polar regions, where the polar ...
    • Lorentz Mapping of Magnetic Fields in Hot Dense Plasmas 

      Amendt, P. A.; Ross, J. S.; Seguin, Fredrick Hampton; Town, R. P. J.; Bettie, R.; e.a. (American Physical Society, 2009-08)
      Unique detection of electromagnetic fields and identification of field type and strength as a function of position were used to determine the nature of self-generated fields in a novel experiment with laser-generated plasma ...
    • Lorentz mapping of magnetic fields in hot, dense plasmas 

      Petrasso, R.D.; Li, C.K.; Seguin, F.H.; Rygg, J.R.; Frenje, J.A.; e.a. (MIT Plasma Science & Fusion Center, 2009-06-25)
    • A Lorentz-force actuated controllable needle-free drug delivery system 

      Hemond, Brian D. (Brian David Thomson) (Massachusetts Institute of Technology, 2004)
      The advantages of delivering injections via needle-free methods are numerous. However, conventional methods for needle-free injection lack sufficient control over depth of penetration and shape of injection. Thus, a ...
    • Lorentz-force actuated needle-free injection for intratympanic pharmaceutical delivery 

      Cloutier, Alison (Alison Marie) (Massachusetts Institute of Technology, 2013)
      Delivery of pharmaceuticals to the inner ear via injection through the tympanic membrane is a method of local drug delivery that provides a non-invasive, outpatient procedure to treat many of the disorders and diseases ...
    • A Lorentz-force actuated needle-free intraocular injection device 

      White, James E (Massachusetts Institute of Technology, 2012)
      Intravitreal injection is a common treatment in ophthalmology, but it can lead to considerable patient anxiety and numerous complications. Lorentz-force actuated needle-free jet injection has been shown to successfully ...
    • The Los Angeles County Museum of Art : an analysis and a grand design. 

      Russell, Juniper Terence (Massachusetts Institute of Technology, 1976)
    • Losartan inhibits collagen I synthesis and improves the distribution and efficacy of nanotherapeutics in tumors 

      Diop-Frimpong, Benjamin; Chauhan, Vikash P.; Krane, Stephen; Boucher, Yves; Jain, Rakesh K. (National Academy of Sciences (U.S.), 2011-02)
      The dense collagen network in tumors significantly reduces the penetration and efficacy of nanotherapeutics. We tested whether losartan—a clinically approved angiotensin II receptor antagonist with noted antifibrotic ...
