• #### Disky dwarf disruption and the shape of the Galactic halo ﻿

(Oxford University Press, 2016-02-02)
The shape of the Galactic dark halo can, in principle, be inferred through modelling of stellar tidal streams in the Milky Way halo. The brightest and the longest of these, the Sagittarius stream, reaches out to large ...
• #### DISK–WIND CONNECTION DURING THE HEARTBEATS OF GRS 1915+105 ﻿

(IOP Publishing, 2016-12-20)
Disk and wind signatures are seen in the soft state of Galactic black holes, while the jet is seen in the hard state. Here we study the disk–wind connection in the ρ class of variability in GRS 1915+105 using a joint ...
• #### Dislocation core structures in (0001) InGaN ﻿

(AIP Publishing, 2016)
Threading dislocation core structures in c-plane GaN and InₓGa₁₋ₓN (0.057 ≤ x ≤ 0.20) films were investigated by aberration-corrected scanning transmission electron microscopy. a-type dislocations are unaffected by alloying ...
• #### Dislocation core structures in Si-doped GaN ﻿

(AIP, 2015-12-15)
Aberration-corrected scanning transmission electron microscopy was used to investigate the core structures of threading dislocations in plan-view geometry of GaNfilms with a range of Si-doping levels and dislocation densities ...
• #### Disorder drives cooperative folding in a multidomain protein ﻿

Many human proteins contain intrinsically disordered regions, and disorder in these proteins can be fundamental to their function – for example, facilitating transient but specific binding, promoting allostery, or allowing ...
• #### Disordered Cellulose-based Nanostructures for Enhanced Light-scattering ﻿

(American Chemical Society, 2017-02-13)
Cellulose is the most abundant biopolymer on Earth. Cellulose fibers, such as the one extracted form cotton or woodpulp, have been used by humankind for hundreds of years to make textiles and paper. Here we show how, by ...
• #### Disordered Gambling: the Evolving Concept of Behavioral Addiction ﻿

(Wiley, 2014)
The reclassification of gambling disorder within the DSM-5 Addictions category marks an important step for addiction science. The similarities between gambling disorder and the substance use disorders have been well-documented. ...
• #### Disorders of compulsivity: a common bias towards learning habits ﻿

(Nature Publishing Group, 2014-05-20)
Why do we repeat choices that we know are bad for us? Decision making is characterized by the parallel engagement of two distinct systems, goal-directed and habitual, thought to arise from two computational learning ...
• #### Dispersion in two-dimensional turbulent buoyant plumes ﻿

(Cambridge University Press, 2015-06-02)
Using high-resolution imaging and dye studies, we investigate experimentally the mixing of a tracer by the eddies within a two-dimensional turbulent buoyant plume. Instantaneously, the plume consists of a series of eddies, ...
• #### Dispersion Studies on Multimode Polymer Spiral Waveguides for Board-Level Optical Interconnects ﻿

(2015-05-18)
Dispersion studies are conducted on 1m long multimode polymer spiral waveguides with different refractive index profiles. Bandwidth-length products >40GHz×m are obtained from such waveguides under a 50/125 μm MMF, indicating ...
• #### A Dispersive approach to Sudakov resummation. ﻿

(High Energy Physics, Cavendish Laboratory, University of Cambridge, 2007-09)
We present a general all–order formulation of Sudakov resummation in QCD in terms of dispersion integrals. We show that the Sudakov exponent can be written as a dispersion integral over spectral density functions, weighted ...
• #### Displaying R spatial statistics on Google dynamic maps with web applications created by Rwui ﻿

(2012-09-24)
Abstract Background The R project includes a large variety of packages designed for spatial statistics. Google dynamic maps provide web based access to global maps and satellite imagery. We describe a method for displaying ...
• #### Disrupted iron regulation in the brain and periphery in cocaine addiction ﻿

(Nature Publishing Group, 2017-02-21)
Stimulant drugs acutely increase dopamine neurotransmission in the brain, and chronic use leads to neuroadaptive changes in the mesolimbic dopamine system and morphological changes in basal ganglia structures. Little is ...
• #### Disrupted PI3K p110δ signalling dysregulates maternal immune cells and increases fetal mortality in mice ﻿

(Elsevier, 2015-12-17)
Maternal immune cells are an integral part of reproduction but how they may cause pregnancy complications remains elusive. Macrophages and their dual function in inflammation and tissue repair are thought to play key, yet ...
• #### Disrupted resting-state brain network properties in obesity: decreased global and putaminal cortico-striatal network efficiency ﻿

(Cambridge University Press, 2016-11-02)
$\textbf{Background}$. The efficient organization and communication of brain networks underlie cognitive processing and their disruption can lead to pathological behaviours. Few studies have focused on whole-brain networks ...
• #### Disrupting the Constitutive, Homodimeric Protein-Protein Interface in CK2β Using a Biophysical Fragment-Based Approach ﻿

(American Chemical Society, 2016-11-02)
Identifying small molecules that induce the disruption of constitutive protein-protein interfaces is a challenging objective. Here, a targeted biophysical screening cascade was employed to specifically identify small ...
• #### Disruption of chromosome 11 in canine fibrosarcomas highlights an unusual variability of CDKN2B in dogs. ﻿

(2009-07-31)
Abstract Background In dogs in the western world neoplasia constitutes the most frequently diagnosed cause of death. Although there appear to be similarities between canine and human cancers, rather little is known about ...
• #### Disruption of SSP/VWI states by a stable stratification ﻿

(Cambridge University Press, 2015-11-06)
We identify ‘minimal seeds’ for turbulence, i.e. initial conditions of the smallest possible total perturbation energy density Ec that trigger turbulence from the laminar state, in stratified plane Couette flow, the flow ...
• #### Disruptive viability selection on a black plumage trait associated with dominance ﻿

(Wiley, 2015-09-14)
Traits used in communication, such as colour signals, are expected to have positive consequences for reproductive success, but their associations with survival are little understood. Previous studies have mainly investigated ...
• #### The disruptor's dilemma: TiVo and the U.S. television ecosystem ﻿

(Wiley, 2015-09-21)
Firms introducing disruptive innovations into multisided ecosystems may confront the disruptor's dilemma – they must gain the support of the very incumbents they disrupt. We examine how these firms may address this dilemma ...
