Dusty disks at the bottom of the initial mass function
(2008-01-01) - Journal articleIsolated planetary-mass objects (IPMOs) have masses close to or below the deuterium-burning mass limit (similar to 15 M-Jup)-at the bottom of the stellar initial mass function. We present an exploratory survey for disks ... -
Dusty gas with one fluid
(2014-05-21) - Journal articleIn this paper, we show how the two-fluid equations describing the evolution of a dust and gas mixture can be re-formulated to describe a single fluid moving with the barycentric velocity of the mixture. This leads to ... -
Dusty gas with one fluid in smoothed particle hydrodynamics
(2014-05-21) - Journal articleIn a companion paper we have shown how the equations describing gas and dust as two fluids coupled by a drag term can be re-formulated to describe the system as a single-fluid mixture. Here, we present a numerical ... -
Dying 'through the law to the law' (Gal. 2.19)
(University of St Andrews, 1990) - ThesisIn the Letter to the Galatians the law has been superseded by Christ's cross and faith in Christ is contrasted to the law. The juxtaposition of the law and the cross occurs in 2.19, where Paul speaks of them in terms ... -
Dynamic changes in gene expression in vivo predict prognosis of tamoxifen-treated patients with breast cancer
(2010-06-22) - Journal articleIntroduction: Tamoxifen is the most widely prescribed anti-estrogen treatment for patients with estrogen receptor (ER)-positive breast cancer. However, there is still a need for biomarkers that reliably predict endocrine ... -
Dynamic covalent assembly and disassembly of nanoparticle aggregates
(2016-07-25) - Journal articleThe quantitative assembly and disassembly of a new type of dynamic covalent nanoparticle (NP) building block is reported. In situ spectroscopic characterization reveals constitutionally adaptive NP-bound monolayers of ... -
Dynamic covalent nanoparticle building blocks
(2016-07-25) - Journal articleRational and generalizable methods for engineering surface functionality will be crucial to realizing the technological potential of nanomaterials. Nanoparticle-bound dynamic covalent exchange combines the error-correcting ... -
Dynamic epigenetic changes to VHL occur with sunitinib in metastatic clear cell renal cancer
(2016-03-23) - Journal articleBackground: Genetic intratumoral heterogeneity (ITH) hinders biomarker development in metastatic clear cell renal cancer (mccRCC). Epigenetic relative to genetic ITH or the presence of consistent epigenetic changes following ... -
Dynamic habitat corridors for marine predators : intensive use of a coastal channel by harbour seals is modulated by tidal currents
(2016-12) - Journal articlePrevious studies have found that predators utilise habitat corridors to ambush prey moving through them. In the marine environment, coastal channels effectively act as habitat corridors for prey movements, and sightings ... -
Dynamic mineral clouds on HD 189733b : I. 3D RHD with kinetic, non-equilibrium cloud formation
(2016-10-10) - Journal articleContext. Observations of exoplanet atmospheres have revealed the presence of cloud particles in their atmospheres. 3D modelling of cloud formation in atmospheres of extrasolar planets coupled to the atmospheric dynamics ... -
A dynamic model of engagement in normative and non-normative collective action : psychological antecedents, consequences, and barriers
(2015) - Journal articleThis review addresses three recent developments in the collective action literature. First, we demonstrate that normative and non-normative collective action participation can be predicted by different psychological ... -
Dynamic modulation of phosphoprotein expression in ovarian cancer xenograft models
(2016-03-10) - Journal articleBackground: The dynamic changes that occur in protein expression after treatment of a cancer in vivo are poorly described. In this study we measure the effect of chemotherapy over time on the expression of a panel of ... -
Dynamic molecular control of nanoparticle building block assembly
(University of St Andrews, 2016-06) - ThesisNanoparticles have generated much excitement as a result of their often unique properties, inherently dependent on nanoparticle material, shape and size. Virtually all conceivable nanoparticle applications will require ... -
Dynamic photoinhibition exhibited by red coralline algae in the red sea
(2014-05-20) - Journal articleBackground: Red coralline algae are critical components of tropical reef systems, and their success and development is, at least in part, dependent on photosynthesis. However, natural variability in the photosynthetic ... -
Dynamic properties of bright points in an active region
(2014-06-20) - Journal articleContext. Bright points (BPs) are small-scale, magnetic features ubiquitous across the solar surface. Previously, we have observed and noted their properties for quiet Sun regions. Here, we determine the dynamic properties ... -
Dynamic size tuning of multidimensional optically bound matter
(2011-09) - Journal articleWe generate and dynamically control one-, two- and three-dimensional optically bound structures of soft matter in the geometry of counter-propagating incoherent laser beams. We report results for the Bessel, Gaussian, and ... -
A dynamical definition of f.g. virtually free groups
(2016-02) - Journal articleWe show that the class of finitely generated virtually free groups is precisely the class of demonstrable subgroups for R. Thompson's group V . The class of demonstrable groups for V consists of all groups which can embed ... -
The dynamical fate of self-gravitating disc fragments after tidal downsizing
(2015-02-11) - Journal articleThe gravitational instability model of planet/brown dwarf formation proposes that protostellar discs can fragment into objectswith masses above a few Jupiter masses at large semimajor axis. Tidal downsizing may reduce both ... -
Dynamical history of the Local Group in ΛCDM
(2016-06-21) - Journal articleThe positions and velocities of galaxies in the Local Group (LG) measure the gravitational field within it. This is mostly due to the Milky Way (MW) and Andromeda (M31). We constrain their masses using distance and radial ... -
Dynamical history of the Local Group in ΛCDM II − including external perturbers In 3D
(2017-05) - Journal articleWe attempt to fit the observed radial velocities (RVs) of ~30 Local Group (LG) galaxies using a 3D dynamical model of it and its immediate environment within the context of the standard cosmological paradigm, ΛCDM. This ...
