Detection of human brain tumor infiltration with quantitative stimulated Raman scattering microscopy
(American Association for the Advancement of Science (AAAS), 2015)Differentiating tumor from normal brain is a major barrier to achieving optimal outcome in brain tumor surgery. New imaging techniques for visualizing tumor margins during surgery are needed to improve surgical results. ... -
Detection of Lipid-Linked Peptidoglycan Precursors by Exploiting an Unexpected Transpeptidase Reaction
(American Chemical Society, 2014)Penicillin-binding proteins (PBPs) are involved in the synthesis and remodeling of bacterial peptidoglycan (PG). Staphylococcus aureus expresses four PBPs. Genetic studies in S. aureus have implicated PBP4 in the formation ... -
A detection of Milankovitch frequencies in global volcanic activity
(Geological Society of America, 2013)A rigorous detection of Milankovitch periodicities in volcanic output across the Pleistocene-Holocene ice age has remained elusive. We report on a spectral analysis of a large number of well-preserved ash plume deposits ... -
Detection of N2D+ in a protoplanetary disk
(IOP Publishing, 2015)Observations of deuterium fractionation in the solar system, and in interstellar and circumstellar material, are commonly used to constrain the formation environment of volatiles. Toward protoplanetary disks, this approach ... -
Detection of Neuron Membranes in Electron Microscopy Images Using Multi-scale Context and Radon-Like Features
(Springer Science + Business Media, 2011)Automated neural circuit reconstruction through electron microscopy (EM) images is a challenging problem. In this paper, we present a novel method that exploits multi-scale contextual information together with Radon-like ... -
Detection of Planetary Emission From the Exoplanet Tres-2 Usingspitzer/irac
(American Astronomical Society, 2010)We present here the results of our observations of TrES-2 using the Infrared Array Camera on Spitzer. We monitored this transiting system during two secondary eclipses, when the planetary emission is blocked by the star. ... -
Detection of Planetary Transits Across a Sun-like Star
(American Astronomical Society, 2000)We report high-precision, high-cadence photometric measurements of the star HD 209458, which is known from radial velocity measurements to have a planetary-mass companion in a close orbit. We detect two separate transit ... -
Detection of Poly- and Perfluoroalkyl Substances (PFASs) in U.S. Drinking Water Linked to Industrial Sites, Military Fire Training Areas, and Wastewater Treatment Plants
(American Chemical Society, 2016)Drinking water contamination with poly- and perfluoroalkyl substances (PFASs) poses risks to the developmental, immune, metabolic, and endocrine health of consumers. We present a spatial analysis of 2013–2015 national ... -
Detection of Radio Emission From the Hyperactive L Dwarf 2mass J13153094−2649513ab
(IOP Publishing, 2012)We report the detection of radio emission from the unusually active L5e + T7 binary 2MASS J13153094−2649513AB made with the Australian Telescope Compact Array. Observations at 5.5 GHz reveal an unresolved source with a ... -
Detection of Single-Molecule Optical Absorption at Room Temperature and Mechanistic Study of Transcriptional Bursting
(2014-06-06)Advances in optical imaging techniques have allowed quantitative studies of many biological systems. This dissertation elaborates on our efforts in both developing novel imaging modalities based on detection of optical ... -
Detection of Thermal Emission from an Extrasolar Planet
(American Astronomical Society, 2005)We present Spitzer Space Telescope infrared photometric time series of the transiting extrasolar planet system TrES-1. The data span a predicted time of secondary eclipse, corresponding to the passage of the planet behind ... -
Detection probabilities for sessile organisms
(Wiley-Blackwell, 2016)Estimation of population sizes and species ranges are central to population and conservation biology. It is widely appreciated that imperfect detection of mobile animals must be accounted for when estimating population ... -
Detective Work in the West Indies: Integrating Historical and Experimental Approaches to Study Island Lizard Evolution
(American Institute of Biological Sciences, 2007)Evolutionary biology is a historical science, like astronomy and geology. Understanding how and why evolution has occurred requires synthesizing multiple lines of inquiry. Historical studies, such as those that estimate ... -
A Determinantal Point Process Latent Variable Model for Inhibition in Neural Spiking Data
(Curran Associates, Inc., 2013)Point processes are popular models of neural spiking behavior as they provide a statistical distribution over temporal sequences of spikes and help to reveal the complexities underlying a series of recorded action potentials. ... -
Determinants of Democracy
(University of Chicago Press, 1999)A panel study of over 100 countries from 1960 to 1995 finds that improvements in the standard of living predict increase in democracy, as measured by a subjective indicator of electoral rights. The propensity for democracy ... -
The Determinants of Mortality
(American Economic Association, 2006)The pleasures of life are worth nothing if one is not alive to experience them. Through the twentieth century in the United States and other high-income countries, growth in real incomes was accompanied by a historically ... -
Determinants of Success and Failure in US Advising of Foreign Militaries, 1945-present
(2017-05-16)Military advising is frequently touted as a high-impact, low-cost strategy that allows the United States to achieve its security goals without deploying combat troops. The US military now considers foreign military advising ... -
Determination and Application of the Equilibrium Oxygen Isotope Effect Between Water and Sulfite
(Elsevier BV, 2014)The information encoded by the two stable isotope systems in sulfate (δ34SSO4 and δ18OSO4) has been widely applied to aid reconstructions of both modern and ancient environments. Interpretation of δ18OSO4 records has been ... -
Determination of DNA-Base Orientation on Carbon Nanotubes through Directional Optical Absorbance
(American Chemical Society, 2007)We develop an approach for determining the orientation of DNA bases attached to carbon nanotubes (CNTs), by combining ab initio time-dependent density functional theory and optical spectroscopy measurements. The structures ... -
