Last Glacial Maximum and deglacial abyssal seawater oxygen isotopic ratios
(Copernicus GmbH, 201606)An earlier analysis of porewater salinity (chlorinity) in two deepsea cores, using terminal constraint methods of control theory, concluded that although a salinity amplification in the abyss was possible during the LGM, ... 
Late Bayesian inference in mental transformations
(Nature Publishing Group, 201810)Many skills rely on performing noisy mental computations on noisy sensory measurements. Bayesian models suggest that humans compensate for measurement noise and reduce behavioral variability by biasing perception toward ... 
Latetime structure of the BunchDavies de Sitter wavefunction
(Institute of Physics Publishing/SISSA, 201511)We examine the late time behavior of the BunchDavies wavefunction for interacting light fields in a de Sitter background. We use perturbative techniques developed in the framework of AdS/CFT, and analytically continue to ... 
Latent hierarchical structural learning for object detection
(Institute of Electrical and Electronics Engineers (IEEE), 201008)We present a latent hierarchical structural learning method for object detection. An object is represented by a mixture of hierarchical tree models where the nodes represent object parts. The nodes can move spatially to ... 
Latent indices in assortative matching models
(The Econometric Society, 201711)A large class of twosided matching models that include both transferable and nontransferable utility result in positive assortative matching along a latent index. Data from matching markets, however, may not exhibit ... 
A Latent Prosurvival Function for the Mir290295 Cluster in Mouse Embryonic Stem Cells
(Public Library of Science, 201105)MicroRNAs (miRNAs) posttranscriptionally regulate the expression of thousands of distinct mRNAs. While some regulatory interactions help to maintain basal cellular functions, others are likely relevant in more specific ... 
A latent serotonin1A receptorgated spinal afferent pathway inhibiting breathing
(Springer Berlin Heidelberg, 201512)Spinal afferents such as nociceptive afferents and group III–IV muscle afferents are known to exert an acute excitatory effect on breathing when activated. Here, we report the surprising existence of latent spinal afferents ... 
A Latent Source Model for Online Collaborative Filtering
(Neural Information Processing Systems Foundation, Inc., 201412)Despite the prevalence of collaborative filtering in recommendation systems, there has been little theoretical development on why and how well it works, especially in the “online” setting, where items are recommended to ... 
A Latent Source Model for PatchBased Image Segmentation
(Springer International Publishing, 201511)Despite the popularity and empirical success of patchbased nearestneighbor and weighted majority voting approaches to medical image segmentation, there has been no theoretical development on when, why, and how well these ... 
Latent topic discovery of clinical concepts from hospital discharge summaries of a heterogeneous patient cohort
(Institute of Electrical and Electronics Engineers (IEEE), 201411)Patients in critical care often exhibit complex disease patterns. A fundamental challenge in clinical research is to identify clinical features that may be characteristic of adverse patient outcomes. In this work, we propose ... 
Latent Variable Graphical Model Selection Via Convex Optimization
(Institute of Electrical and Electronics Engineers (IEEE), 201102)Suppose we have samples of a subset of a collection of random variables. No additional information is provided about the number of latent variables, nor of the relationship between the latent and observed variables. Is it ... 
Latent variable graphical model selection via convex optimization
(Institute of Mathematical Statistics, 2012)Suppose we observe samples of a subset of a collection of random variables. No additional information is provided about the number of latent variables, nor of the relationship between the latent and observed variables. Is ... 
A latent variable ranking model for contentbased retrieval
(Springer Berlin / Heidelberg, 201204)Since their introduction, ranking SVM models [11] have become a powerful tool for training contentbased retrieval systems. All we need for training a model are retrieval examples in the form of triplet constraints, i.e. ... 
Lateral heterojunction photodetector consisting of molecular organic and colloidal quantum dot thin films
(American Institute of Physics, 200901)We demonstrate a heterojunction photodetector of lateral geometry that utilizes an evaporated film of the holetransporting molecular material N,N′bis(3methylphenyl)N,N′bis(phenyl)9,9spirobifluorene (spiroTPD) as a ... 
Lateral Shift Makes a GroundPlane Cloak Detectable
(American Physical Society, 201006)We examine the effectiveness of the groundplane invisibility cloak generated from quasiconformal mapping of electromagnetic space. This cloak without anisotropy will generally lead to a lateral shift of the scattered wave, ... 
Lateralization of face processing in the human brain
(Cambridge University Press, 201201)Are visual face processing mechanisms the same in the left and right cerebral hemispheres? The possibility of such ‘duplicated processing’ seems puzzling in terms of neural resource usage, and we currently lack a precise ... 
A latitudedependent analysis of the leptonic hypothesis for the Fermi Bubbles
(Oxford University Press (OUP), 201703)The Fermi Bubbles are giant Galactic structures observed in both gammarays and microwaves. Recent studies have found support for the hypothesis that the gammaray and microwave emission can both be understood as arising ... 
The LatMix Summer Campaign: Submesoscale Stirring in the Upper Ocean
(American Meteorological Society, 201508)Lateral stirring is a basic oceanographic phenomenon affecting the distribution of physical, chemical, and biological fields. Eddy stirring at scales on the order of 100 km (the mesoscale) is fairly well understood and ... 
Lattice Boltzmann method for multiscale selfconsistent field theory simulations of block copolymers
(American Institute of Physics (AIP), 201303)A new Lattice Boltzmann (LB) approach is introduced to solve for the block copolymer propagator in polymer field theory. This method bridges two desired properties from different numerical techniques, namely: (i) it is ... 
Lattice ellipsoidal statistical BGK model for thermal nonequilibrium flows
(Cambridge University Press, 201302)A thermal lattice Boltzmann model is constructed on the basis of the ellipsoidal statistical Bhatnagar–Gross–Krook (ESBGK) collision operator via the Hermite moment representation. The resulting lattice ESBGK model uses ...
