A diffusive matrix model for invariant β-ensembles
(Institute of Mathematical Statistics, 2012-06)We define a new diffusive matrix model converging towards the β -Dyson Brownian motion for all β ∈ [0 , 2] that provides an explicit construction of β -ensembles of ran- dom matrices that is invariant under the orthogonal/unitary ... -
Diffusive Phonons in Nongray Nanostructures
(American Society of Mechanical Engineers (ASME), 2018-10)Nanostructured semiconducting materials are promising candidates for thermoelectrics (TEs) due to their potential to suppress phonon transport while preserving electrical properties. Modeling phonon-boundary scattering in ... -
Diffusive-to-ballistic transition in grain boundary motion studied by atomistic simulations
(American Physical Society, 2011-12)An adapted simulation method is used to systematically study grain boundary motion at velocities and driving forces across more than five orders of magnitude. This analysis reveals that grain boundary migration can occur ... -

Digging Deeper: Observing Primordial Gravitational Waves below the Binary-Black-Hole-Produced Stochastic Background
(American Physical Society, 2017-04)The merger rate of black hole binaries inferred from the detections in the first Advanced LIGO science run implies that a stochastic background produced by a cosmological population of mergers will likely mask the primordial ... -
Digit Ratio Predicts Sense of Direction in Women
(Public Library of Science, 2012-02)The relative length of the second-to-fourth digits (2D:4D) has been linked with prenatal androgen in humans. The 2D:4D is sexually dimorphic, with lower values in males than females, and appears to correlate with diverse ... -
Digital and analog gene circuits for biotechnology
(Wiley Blackwell, 2014-05)Biotechnology offers the promise of valuable chemical production via microbial processing of renewable and inexpensive substrates. Thus far, static metabolic engineering strategies have enabled this field to advance ... -

Digital Clock Drawing: Differentiating “Thinking” versus “Doing” in Younger and Older Adults with Depression
(Cambridge University Press, 2014-09)Psychomotor slowing has been documented in depression. The digital Clock Drawing Test (dCDT) provides: (i) a novel technique to assess both cognitive and motor aspects of psychomotor speed within the same task and (ii) the ... -
Digital Construction Platform: A Compound Arm Approach
(Springer-Verlag, 2014)We introduce a novel large-scale Digital Construction Platform (DCP) for on-site sensing, analysis, and fabrication. The DCP is an in-progress research project consisting of a compound robotic arm system comprised of a ... -
Digital CRISPR-based method for the rapid detection and absolute quantification of nucleic acids
(Elsevier BV, 2021)Rapid diagnostics of adventitious agents in biopharmaceutical/cell manufacturing release testing and the fight against viral infection have become critical. Quantitative real-time PCR and CRISPR-based methods rapidly detect ... -
Digital Data, Platforms and the Usual [Antitrust] Suspects: Network Effects, Switching Costs, Essential Facility
(Springer US, 2019-02-13)Abstract This paper asks whether the large amounts of digital data that are typically observed on large technology platforms—such as Google, Facebook, Uber and Amazon—typically give rise to structural ... -
Digital design of multimaterial photonic particles
(National Academy of Sciences (U.S.), 2016-06)Scattering of light from dielectric particles whose size is on the order of an optical wavelength underlies a plethora of visual phenomena in nature and is a foundation for optical coatings and paints. Tailoring the internal ... -
