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 ... -
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-Sweeps: A scalable, parallel preconditioner for the high-frequency Helmholtz equation
(Elsevier BV, 2020)© 2020 Elsevier Inc. We present the first fast solver for the high-frequency Helmholtz equation that scales optimally in parallel for a single right-hand side. The L-sweeps approach achieves this scalability by departing ... -
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 Learners Do Not Ignore Verb’s Subcategorization Information in Real-Time Syntactic Processing
(Frontiers Media SA, 2022)<jats:p>This study addressed the question of whether L2 learners are able to utilize verb’s argument structure information in online structural analysis. Previous L2 research has shown that L2 learners have difficulty in ... -
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 ... -
LAB-1 Targets PP1 and Restricts Aurora B Kinase upon Entrance into Meiosis to Promote Sister Chromatid Cohesion
(Public Library of Science, 2012-08)Successful execution of the meiotic program depends on the timely establishment and removal of sister chromatid cohesion. LAB-1 has been proposed to act in the latter by preventing the premature removal of the meiosis-specific ... -
Lab-on-fiber optofluidic platform for in situ monitoring of drug release from therapeutic eluting polyelectrolyte multilayers
(Optical Society of America, 2015-07)A lab-on-fiber (LOF) optofluidic platform that provides physiologically relevant microenvironment was developed by integrating a long period grating (LPG) coupled with high order cladding mode to achieve high index sensitivity ... -
Lab-to-Market Design of an Electrodialysis-Based Home-Scale Water Desalination System
(American Society of Mechanical Engineers, 2023-08-20)Water scarcity is increasingly becoming a problem in India, so much so that a recently proposed piece of legislation would mandate home-scale water desalination systems to have a 60% recovery ratio [1], significantly higher ... -
Label Fusion: A Pipeline for Generating Ground Truth Labels for Real RGBD Data of Cluttered Scenes
(Institute of Electrical and Electronics Engineers (IEEE), 2018-09)Deep neural network (DNN) architectures have been shown to outperform traditional pipelines for object segmentation and pose estimation using RGBD data, but the performance of these DNN pipelines is directly tied to how ... -
Label-free biomarker sensing in undiluted serum with suspended microchannel resonators
(American Chemical Society, 2010-02)Improved methods are needed for routine, inexpensive monitoring of biomarkers that could facilitate earlier detection and characterization of cancer. Suspended microchannel resonators (SMRs) are highly sensitive, ... -
Label-free characterization of ultra violet-radiation-induced changes in skin fibroblasts with Raman spectroscopy and quantitative phase microscopy
