Decoding the precision of historical temperature observations
(Wiley-Blackwell, 2015)Historical observations of temperature underpin our ability to monitor Earth’s climate. We identify a pervasive issue in archived observations from surface stations, wherein the use of varying conventions for units and ... -
Decoherence Dynamics in Low-Dimensional Cold Atom Interferometers
(American Physical Society (APS), 2007)We report on a study of the dynamics of decoherence of a matter-wave interferometer, consisting of a pair of low-dimensional cold atom condensates at finite temperature. We identify two distinct regimes in the time dependence ... -
Decoherence imaging of spin ensembles using a scanning single-electron spin in diamond
(Nature Publishing Group, 2015)The nitrogen-vacancy (NV) defect center in diamond has demonstrated great capability for nanoscale magnetic sensing and imaging for both static and periodically modulated target fields. However, it remains a challenge to ... -
Deconfined criticality in bilayer graphene
(American Physical Society (APS), 2014)We propose that bilayer graphene can provide an experimental realization of deconfined criticality. Current experiments indicate the presence of Néel order in the presence of a moderate magnetic field. The Néel order can ... -
Deconstructing Disease

Deconstructing, Reconstructing, Preserving Paul E Meehl's Legacy of Construct Validity
(American Psychological Association, 2005)The question of the status of cause-and-effect explanations of human behavior that posit physically existing causative factors and those that, on the other hand, posit hypothetical entities in the form of "useful fictions" ... -
Deconstruction and gauge theories in AdS5
(Springer Verlag, 2003) -
Decoupling catalytic activity from biological function of the ATPase that powers lipopolysaccharide transport
(Proceedings of the National Academy of Sciences, 2014)Gram-negative bacteria contain an unusual outer membrane that prevents the entry of most currently available antibiotics. This membrane contains a complex glycolipid, LPS, on the exterior. It is not understood how such a ... -
Decoupling of the Arctic Oscillation and North Atlantic Oscillation in a Warmer Climate
(Springer Science and Business Media LLC, 2021-01-11)The North Atlantic Oscillation and the Arctic Oscillation are modes of climate variability affecting temperature and precipitation in the mid-latitudes. Here we use reanalysis data and climate model simulations of historical ... -
Decrease in gamma-band activity tracks sequence learning
(Frontiers Media S.A., 2015)Learning novel sequences constitutes an example of declarative memory formation, involving conscious recall of temporal events. Performance in sequence learning tasks improves with repetition and involves forming temporal ... -
Decreased Cerebellar-Orbitofrontal Connectivity Correlates with Stuttering Severity: Whole-Brain Functional and Structural Connectivity Associations with Persistent Developmental Stuttering
(Frontiers Media S.A., 2016)Persistent developmental stuttering is characterized by speech production disfluency and affects 1% of adults. The degree of impairment varies widely across individuals and the neural mechanisms underlying the disorder and ... -
The Dedication Strategies of Conrad Gessner
(Springer International Publishing, 2017) -
Deduction of Continuum Potentials from Planar Channeling
(American Physical Society (APS), 1972)A new method for determining planar continuum potentials from planar channeling data has been developed. Preliminary experiments have been done for 1.8-MeV α particles in [111] gold planar directions from which the continuum ... -
Deep Annotation of Populus trichocarpa MicroRNAs from Diverse Tissue Sets
(Public Library of Science, 2012)Populus trichocarpa is an important woody model organism whose entire genome has been sequenced. This resource has facilitated the annotation of microRNAs (miRNAs), which are short non-coding RNAs with critical regulatory ... -
Deep Genetic Divergence between Disjunct Refugia in the Arctic-Alpine King’s Crown, Rhodiola integrifolia (Crassulaceae)
(Public Library of Science, 2013)Despite the strength of climatic variability at high latitudes and upper elevations, we still do not fully understand how plants in North America that are distributed between Arctic and alpine areas responded to the ... -
The Deep History of Life
(ASM Press, 2012)The conventional fossil record is built of hard parts—bones, shells, and decay-resistant organic tissues buried in the sediments that accumulate on floodplains, in lakes, and on the seafloor. In the 1950s, geologists first ... -
Deep Predictive Coding Networks for Video Prediction and Unsupervised Learning
(2016)While great strides have been made in using deep learning algorithms to solve supervised learning tasks, the problem of unsupervised learning - leveraging unlabeled examples to learn about the structure of a domain - remains ... -
Deep Sequencing Analysis of Phage Libraries using Illumina Platform
(Elsevier BV, 2012)This paper presents an analysis of phage-displayed libraries of peptides using Illumina. We describe steps for the preparation of short DNA fragments for deep sequencing and MatLab software for the analysis of the results. ... -
Deep Sequencing of Mixed Total DNA without Barcodes Allows Efficient Assembly of Highly Plastic Ascidian Mitochondrial Genomes
(Oxford University Press, 2013)Ascidians or sea squirts form a diverse group within chordates, which includes a few thousand members of marine sessile filter-feeding animals. Their mitochondrial genomes are characterized by particularly high evolutionary ... -
Deep sequencing reveals cell-type-specific patterns of single-cell transcriptome variation
(BioMed Central, 2015)Background: Differentiation of metazoan cells requires execution of different gene expression programs but recent single-cell transcriptome profiling has revealed considerable variation within cells of seeming identical ...
