W + W − boson pair production in proton-proton collisions at √ s = 13 TeV
(American Physical Society (APS), 2020)© 2020 CERN. A measurement of the W+W- boson pair production cross section in proton-proton collisions at s=13 TeV is presented. The data used in this study are collected with the CMS detector at the CERN LHC and correspond ... -
W-boson polarization measurement in the t t ¯ dilepton channel using the CDF II detector
(Elsevier BV, 2013)© 2013 Elsevier B.V. All rights reserved. We present a measurement of the W-boson polarization in top-quark decays in tt- events with decays to dilepton final states using data corresponding to 5.1 fb-1 of integrated ... -

W-state Analyzer and Multi-party Measurement-device-independent Quantum Key Distribution
(Nature Publishing Group, 2015-12)W-state is an important resource for many quantum information processing tasks. In this paper, we for the first time propose a multi-party measurement-device-independent quantum key distribution (MDI-QKD) protocol based ... -
WaaZam!: supporting creative play at a distance in customized video environments
(Association for Computing Machinery, 2014-05)We present the design, and evaluation of WaaZam, a video mediated communication system designed to support creative play in customized environments. Users can interact together in virtual environments composed of digital ... -
WACO: Learning Workload-Aware Co-optimization of the Format and Schedule of a Sparse Tensor Program

Wafer integrated micro-scale concentrating photovoltaics
(American Institute of Physics (AIP), 2017-09)Recent development of a novel micro-scale PV/CPV technology is presented. The Wafer Integrated Micro-scale PV approach (WPV) seamlessly integrates multijunction micro-cells with a multi-functional silicon platform that ... -

Wafer-scale 3D integration of InGaAs image sensors with Si readout circuits
(Institute of Electrical and Electronics Engineers, 2009-10)In this work, we modified our wafer-scale 3D integration technique, originally developed for Si, to hybridize InP-based image sensor arrays with Si readout circuits. InGaAs image arrays based on the InGaAs layer grown on ... -
Wafer-scale 3D integration of silicon-on-insulator RF amplifiers
(Institute of Electrical and Electronics Engineers, 2009-02)RF amplifiers are demonstrated using a three- dimensional (3D) wafer-scale integration technology based on silicon-on-insulator (SOI) CMOS process. This new 3D implementation reduces the amplifier size and shortens ... -
Wages and the Value of Nonemployment*
(Oxford University Press (OUP), 2020)<jats:title>Abstract</jats:title> <jats:p>Nonemployment is often posited as a worker’s outside option in wage-setting models such as bargaining and wage posting. The value of nonemployment is therefore a key ... -
Wait-learning: Leveraging conversational dead time for second language education
(Association for Computing Machinery (ACM), 2014-04)Second-language learners are often unable to find time for language practice due to constraints in their daily lives. In this paper, we examine how brief moments of waiting during a person's existing social conversations ... -
Wait-Learning: Leveraging Wait Time for Second Language Education
(Association for Computing Machinery, 2015-04)Competing priorities in daily life make it difficult for those with a casual interest in learning to set aside time for regular practice. In this paper, we explore wait-learning: leveraging brief moments of waiting during ... -
Waiting to Vote
(Mary Ann Lieber, 2015-03)We review evidence that long lines waiting to vote in the 2012 presidential election were costly and disproportionately appeared in certain regions of the country, in cities, and among minority voters. We argue that the ... -
WaitSuite: Productive Use of Diverse Waiting Moments
(Association for Computing Machinery (ACM), 2017-03)The busyness of daily life makes it difficult to find time for informal learning. Yet, learning requires significant time and effort, with repeated exposures to educational content on a recurring basis. Despite the struggle ... -
Wake Capture, Particle Breakup, and Other Artifacts Associated with Counterflow Virtual Impaction
(Taylor & Francis, 2011-03)Counterflow virtual impaction is used to inertially separate cloud elements from inactivated aerosol. Previous airborne, ground-based, and laboratory studies using this technique exhibit artifacts that are not fully explained ... -
Wake of a heavy quark in non-Abelian plasmas: Comparing kinetic theory and the anti-de Sitter space/conformal field theory correspondence
(American Physical Society, 2012-06)We compute the nonequilibrium stress tensor induced by a heavy quark moving through weakly coupled QCD plasma at the speed of light and compare the result to N=4 super-Yang-Mills theory at strong coupling. The QCD Boltzmann ... -
Wake structure and sediment deposition behind models of submerged vegetation with and without flexible leaves
(Elsevier BV, 2018-08)This laboratory study explored the flow structure and pattern of deposition directly downstream of submerged patches of vegetation, focusing on whether, or not, the presence of flexible trailing leaves enhanced deposition. ... -
The wake structure behind a porous obstruction and its implications for deposition near a finite patch of emergent vegetation
(American Geophysical Union (Wiley platform), 2012-09)This experimental study describes the mean and turbulent flow structure in the wake of a circular array of cylinders, which is a model for a patch of emergent vegetation. The patch diameter, D, and patch density, a (frontal ... -
Wake-body Resonance of Long Flexible Structures is Dominated by Counterclockwise Orbits
(American Physical Society (APS), 2011-09)We identify a dominant mechanism in the interaction between a slender flexible structure undergoing free vibrations in sheared cross-flow and the vortices forming in its wake: energy is transferred from the fluid to the ...
