A multi-model assessment of regional climate disparities caused by solar geoengineering
(IOP Publishing, 2014)Global-scale solar geoengineering is the deliberate modification of the climate system to offset some amount of anthropogenic climate change by reducing the amount of incident solar radiation at the surface. These changes ... -
A multi-modular tensegrity model of an actin stress fiber
(Elsevier, 2008)Stress fibers are contractile bundles in the cytoskeleton that stabilize cell structure by exerting traction forces on the extracellular matrix. Individual stress fibers are molecular bundles composed of parallel actin ... -
Multi-omics interrogation of metabolic stress in cancer
(2024-03-12)Cancer is associated with alterations to many pathways and cellular processes, including activation of pro-growth cell signaling pathways, resistance to cell death, activation of metastasis, and evasion of the immune system. ... -
A Multi-Ringed, Modestly Inclined Protoplanetary Disk Around AA Tau
(American Astronomical Society, 2017-05-02)AA Tau is the archetype for a class of stars with a peculiar periodic photometric variability thought to be related to a warped inner disk structure with a nearly edge-on viewing geometry. We present high resolution ... -
Multi-scale architectured thermoelectric materials in the Mg2(Si,Sn) system
(Elsevier BV, 2016)Two different microstructural architectures featuring multiple length scales have been created in the thermoelectric Mg2(SixSn1−x) system. The first one combines the nano-grain microstructure, characteristic of rapid ... -
Multi-Scale Capture of Facial Geometry and Motion
(Association for Computing Machinery, 2007)We present a novel multi-scale representation and acquisition method for the animation of high-resolution facial geometry and wrinkles. We first acquire a static scan of the face including reflectance data at the highest ... -
Multi-scale Image Harmonization
(Association for Computing Machinery, 2010)Traditional image compositing techniques, such as alpha matting and gradient domain compositing, are used to create composites that have plausible boundaries. But when applied to images taken from different sources or shot ... -
A multi-scale map of cell structure fusing protein images and interactions
(Springer Science and Business Media LLC, 2021-11-24)The eukaryotic cell is a multi-scale structure with modular organization across at least four orders of magnitude<jats:sup>1,2</jats:sup>. Two central approaches for mapping this structure – protein fluorescent imaging and ... -
Multi-Scale Theoretical Investigations of Protein Interactions and Evolution
(2016-05-12)Evolution of biological systems requires players of multiple layers, from atoms and molecules to organisms and populations. Expression of a gene is operated by molecular machineries for transcription, translation, regulation, ... -
Multi-Sender Cheap Talk with Restricted State Spaces
(Society for Economic Theory, 2008)This paper analyzes multi-sender cheap talk when the state space might be restricted, either because the policy space is restricted, or the set of rationalizable policies of the receiver is not the whole space. We provide ... -
A Multi-Site Analysis of Random Error in Tower-Based Measurements of Carbon and Energy Fluxes
(Elsevier, 2006)Measured surface-atmosphere fluxes of energy (sensible heat, <i>H</i>, and latent heat, LE) and CO2 (<i>F</i>CO2) represent the "true" flux plus or minus potential random and systematic measurement errors. Here, we use data ... -
Multi-Site Reactivity: Reduction of Six Equivalents of Nitrite To Give an Fe 6 (NO) 6 Cluster with a Dramatically Expanded Octahedral Core
(American Chemical Society (ACS), 2011)Reaction of NO2– with the octahedral cluster (HL)2Fe6 in the presence of a proton source affords the hexanitrosyl cluster (HL)2Fe6(NO)6. This species forms via a proton-induced reduction of six nitrite molecules per cluster, ... -
Multi-Task Bayesian Optimization
(Curran Associates, Inc., 2013)Bayesian optimization has recently been proposed as a framework for automatically tuning the hyperparameters of machine learning models and has been shown to yield state-of-the-art performance with impressive ease and ... -
Multi-Task Reinforcement Learning in Humans
(Nature publishing group, 2021-01-28)The ability to transfer knowledge across tasks and generalize to novel ones is an important hallmark of human intelligence. Yet not much is known about human multi-task reinforcement learning. We study participants’ behavior ... -
Multi-terminal transport measurements of MoS2 using a van der Waals heterostructure device platform
(Nature Publishing Group, 2015)Atomically thin two-dimensional semiconductors such as MoS2 hold great promise in electrical, optical, and mechanical devices and display novel physical phenomena. However, the electron mobility of mono- and few-layer MoS2 ... -
Multi-View Decision Processes: The Helper-AI Problem
We consider a two-player sequential game in which agents have the same reward function but may disagree on the transition probabilities of an underlying Markovian model of the world. By committing to play a specific policy, ... -
Multi-Wavelength Observations of the Radio Magnetar PSR J1622–4950 and Discovery of its Possibly Associated Supernova Remnant
(IOP Publishing, 2012)We present multi-wavelength observations of the radio magnetar PSR J1622-4950 and its environment. Observations of PSR J1622-4950 with Chandra (in 2007 and 2009) and XMM (in 2011) show that the X-ray flux of PSR J1622-4950 ... -

Multi-way blockmodels for analyzing coordinated high-dimensional responses
(Institute of Mathematical Statistics, 2013)We consider the problem of quantifying temporal coordination between multiple high-dimensional responses. We introduce a family of multi-way stochastic blockmodels suited for this problem, which avoids preprocessing steps ... -
Multiagent Cooperative Search for Portfolio Selection
(Elsevier, 2001)We present a new multiagent model for the multiperiod portfolio selection problem. A system of cooperative agents divide initial wealth and follow individual worst-case optimal investment strategies from random portfolios, ...
