Domains within Domains and Walls within Walls: Evidence for Polar Domains in Cryogenic SrTiO3
(American Physical Society, 2013-12-11)Resonant piezoelectric spectroscopy shows polar resonances in paraelectric SrTiO3 at temperatures below 80 K. These resonances become strong at T<40 K. The resonances are induced by weak electric fields and lead to standing ... -
Domesticating the Reformation: Material Culture, Memory and Confessional Identity in Early Modern England
(University of Chicago Press, 2016-06-01)This article explores domestic artifacts that testify to the afterlife of the European Reformation in the British Isles. Focusing especially on decorated and commemorative delftware, it investigates how the memory of the ... -
DOMINO-AD protocol: donepezil and memantine in moderate to severe Alzheimer's disease - a multicentre RCT
(2009-07-24)Abstract Background Alzheimer's disease (AD) is the commonest cause of dementia. Cholinesterase inhibitors, such as donepezil, are the drug class with the best evidence of efficacy, licensed for mild to moderate AD, while ... -

Don’t Interrupt Me While I Type: Inferring Text Entered Through Gesture Typing on Android Keyboards
(De Gruyter, 2016)We present a new side-channel attack against soft keyboards that support gesture typing on Android smartphones. An application without any special permissions can observe the number and timing of the screen hardware ... -
Dopamine and memory dedifferentiation in aging
(Elsevier, 2015-03-21)The dedifferentiation theory of aging proposes that a reduction in the specificity of neural representations causes declines in complex cognition as people get older, and may reflect a reduction in dopaminergic signaling. ... -
Dopamine D2-Receptor Blockade Enhances Decoding of Prefrontal Signals in Humans
(Society for Neuroscience, 2015-03-04)The prefrontal cortex houses representations critical for ongoing and future behavior expressed in the form of patterns of neural activity. Dopamine has long been suggested to play a key role in the integrity of such ... -
Dopamine modulates the neural representation of subjective value of food in hungry subjects
(Society for Neuroscience, 2014-12-10)While there is a rich literature on the role of dopamine in value learning, much less is known about its role in using established value estimations to shape decision-making. Here we investigated the effect of dopaminergic ... -
Dopamine neuron-specific optogenetic stimulation in Rhesus macaques
(Elsevier (Cell Press), 2016)Optogenetic studies in mice have revealed new relationships between well-defined neurons and brain functions. However, there are currently no means to achieve the same cell-type specificity in monkeys, which possess an ... -
Dopamine signals for reward value and risk: basic and recent data
(2010-04-23)Abstract Background Previous lesion, electrical self-stimulation and drug addiction studies suggest that the midbrain dopamine systems are parts of the reward system of the brain. This review provides an updated overview ... -
Dopaminergic modulation of positive expectations for goal-directed action: evidence from Parkinson’s disease
(Frontiers, 2015-10-08)Parkinson’s disease (PD) impairs the control of movement and cognition, including the planning of action and its consequences. This provides the opportunity to study the dopaminergic influences on the perception and awareness ... -
Dopant profiling based on scanning electron and helium ion microscopy
(Elsevier, 2015-10-19)In this paper, we evaluate and compare doping contrast generated inside the scanning electron microscope (SEM) and scanning helium ion microscope (SHIM). Specialised energy-filtering techniques are often required to produce ... -
Doping stability and opto-electronic performance of CVD graphene on transparent flexible substrates
(2014-07-15)The primary barrier to wider commercial adoption of graphene lies in reducing the sheet resistance of the transferred material without compromising its high broad-band optical transparency, ideally through the use of ... -
Dose–response relationship between sports activity and musculoskeletal pain in adolescents
(Wolters Kluwer, 2016-06-01)Physical activity has multiple health benefits, but may also increase the risk of developing musculoskeletal pain. However, the relationship between physical activity and musculoskeletal pain has not been well-characterized. ... -
Double Parton Distributions Incorporating Perturbative QCD Evolution and Momentum and Quark Number Sum Rules.
(High Energy Physics, Department of Physics,University of Cambridge, 2009-10)It is anticipated that hard double parton scatterings will occur frequently in the collisions of the LHC, producing interesting signals and significant backgrounds to certain single scattering processes. For double ... -
The double peak in upwelling and heating in the tropical lower stratosphere.
(American Meteorological Society, 2016-04-15)The processes responsible for double peak latitudinal structures in the time averaged tropical lower stratospheric upwelling, centred near 70hPa and 20º N–S, previously noted in ERA-Interim and other reanalysis and model ... -
Double peak-induced distance error in short-time-Fourier-transform-Brillouin optical time domain reflectometers event detection and the recovery method
(The Optical Society, 2015-09-21)The measured distance error caused by double peaks in the BOTDRs (Brillouin optical time domain reflectometers) system is a kind of Brillouin scattering spectrum (BSS) deformation, discussed and simulated for the first ... -
Double Wall Carbon Nanotubes for Wide-Band, Ultrafast Pulse Generation
(ACS Publications, 2014-04-15)We demonstrate wide-band ultrafast optical pulse generation at 1, 1.5, and 2 μm using a single-polymer composite saturable absorber based on double-wall carbon nanotubes (DWNTs). The freestanding optical quality polymer ... -
A Double-Blind, Placebo-Controlled Trial of N-Acetyl Cysteine in the Treatment of Excoriation Disorder
(American Medical Association, 2016-03-23)Importance: Excoriation (skin-picking) disorder (SPD) is a disabling, under-recognized condition in which individuals repeatedly pick at their skin, leading to noticeable tissue damage. To date there has been no clearly ... -
Double-stranded microRNA mimics can induce length- and passenger strand-dependent effects in a cell type-specific manner
(RNA Society, 2015-12-15)MicroRNAs are short (17–26) noncoding RNAs driving or modulating physiological and pathological cellular events. Overexpression of miR-155 is pathogenic in B-cell malignancy but was also reported in a number of solid ...
