The L 98-59 system: three transiting, terrestrial-size planets orbiting a nearby M dwarf
(American Astronomical Society, 2019-07)We report the Transiting Exoplanet Survey Satellite (TESS) discovery of three terrestrial-size planets transiting L 98-59 (TOI-175, TIC 307210830) - a bright M dwarf at a distance of 10.6 pc. Using the Gaia-measured distance ... -
The "L" is for living : creating urban development linkages with affordable transit-oriented housing
(Massachusetts Institute of Technology, 2009)What is a city? Who is the city for? A citizen's answer to these questions is closely connected with her or his sense of political power or representation in the city. Harvey Molotch argues that politically influential ... -
The L%LINES Package
(MIT Artificial Intelligence Laboratory, 1971)The program (L%LINES X Y) takes feature point output from the FP%FPOINTS program (q.v.) for horizontal and vertical scans (X and Y respectively); and outputs a list consisting of two lists of line segments, represented in ... -
L'appareil de l'architecture moderne : new materials and architectural modernity in France, 1889-1934
(Massachusetts Institute of Technology, 1997)This dissertation is an historical inquiry into the role played by new building materials in the formation of architectural modernism in France. It proceeds on the theoretical assumption that a "material" is not a technical ... -
The L- to H-mode transition and momentum confinement in Alcator C-Mod plasmas
(Massachusetts Institute of Technology, 2010)Using a spatially-resolving x-ray spectrometer system, toroidal impurity rotation in Alcator C-Mod plasmas was measured. The propagation of the rotational velocity from the edge to the core of the plasma column was measured ... -
L-band vegetation optical depth and effective scattering albedo estimation from SMAP
(Elsevier BV, 2017-07)Over land the vegetation canopy affects the microwave brightness temperature by emission, scattering and attenuation of surface soil emission. Attenuation, as represented by vegetation optical depth (VOD), is a potentially ... -

L.A. Micro-Publics : expanding the seams of the transportation system
(Massachusetts Institute of Technology, 2012)The global city is the privileged site of "repositioning ... citizenship in practice," where traditional notions of identity and citizenship are being radically reconstructed. This thesis examines contemporary Los Angeles ... -

L2 Gain Stability of Switched Output Feedback Controllers for a Class of LTI Systems
(Institute of Electrical and Electronics Engineers, 2009-07)Our previous work has been devoted to designing asymptotically stabilizing switching controllers for a class of second order LTI plants. Here, we extend the results of our previous work by proving that, when a plant can ... -
L2 processing as noisy channel language comprehension
(Cambridge University Press, 2016-09)The thesis in this paper is that L2 speakers differ from L1 speakers in their ability to do memory storage and retrieval about linguistic structure. We would like to suggest it is possible to go farther than this thesis ... -

L[subscript 1] Adaptive Control for Indoor Autonomous Vehicles: Design Process and Flight Testing
(American Institute of Aeronautics and Astronautics, 2009-08)Adaptive control techniques have the potential to address many of the special performance and robustness requirements of flight control for unmanned aerial vehicles. L[subscript 1] adaptive control offers potential benefits ... -
The L[subscript 1] penalized LAD estimator for high dimensional linear regression
(Elsevier, 2013-04)In this paper, the high-dimensional sparse linear regression model is considered, where the overall number of variables is larger than the number of observations. We investigate the L[subscript 1] penalized least absolute ... -
The l[subscript 1]-l[subscript 2] regularization framework unmasks the hypoxia signature hidden in the transcriptome of a set of heterogeneous neuroblastoma cell lines
(BioMed Central, 2009-10)Background: Gene expression signatures are clusters of genes discriminating different statuses of the cells and their definition is critical for understanding the molecular bases of diseases. The identification of a gene ... -
L[subscript 2]-gain optimization for robust bipedal walking on unknown terrain
(Institute of Electrical and Electronics Engineers (IEEE), 2013-05)In this paper we seek to quantify and explicitly optimize the robustness of a control system for a robot walking on terrain with uncertain geometry. Geometric perturbations to the terrain enter the equations of motion ... -
L[subscript g] = 60 nm recessed In[subscript 0.7]Ga[subscript 0.3]As metal-oxide-semiconductor field-effect transistors with Al[subscript 2]O[subscript 3] insulator
(American Institute of Physics (AIP), 2012-11)In this Letter, we report on sub-100 nm recessed In[subscript 0.7]Ga[subscript 0.3]As metal-oxide-semiconductorfield-effect transistors(MOSFETs) with outstanding logic and high-frequency performance. The device features ...
