Journal ArticleDOI
Temperature Dependence of the Nitrogen-Vacancy Magnetic Resonance in Diamond
Victor M. Acosta,Erik Bauch,Erik Bauch,Micah P. Ledbetter,A. Waxman,Louis-S. Bouchard,Dmitry Budker,Dmitry Budker +7 more
TL;DR: The temperature dependence of the ZFS parameters presents a significant challenge for diamond magnetometers and may ultimately limit their bandwidth and sensitivity.
Journal ArticleDOI
NOTCH1 is a mechanosensor in adult arteries
Julia J. Mack,Thiago Mosqueiro,Brian J. Archer,William M. Jones,Hannah Sunshine,Guido C. Faas,Anaïs Briot,Raquel Aragón,Trent Su,Milagros C. Romay,Austin I. McDonald,Cheng Hsiang Kuo,Carlos Lizama,Timothy F. Lane,Ann C. Zovein,Yun Fang,Elizabeth J. Tarling,Thomas Q. de Aguiar Vallim,Mohamad Navab,Alan M. Fogelman,Louis-S. Bouchard,M. Luisa Iruela-Arispe +21 more
TL;DR: It is proposed that NOTCH1 is atheroprotective and acts as a mechanosensor in adult arteries, where it ensures junctional integrity through modulation of calcium signalling and limits atherosclerosis.
Journal ArticleDOI
NMR Imaging of Catalytic Hydrogenation in Microreactors with the Use of para-Hydrogen
Louis-S. Bouchard,Scott R. Burt,M. Sabieh Anwar,Kirill V. Kovtunov,Igor V. Koptyug,Alexander Pines +5 more
TL;DR: In this article, the authors demonstrate techniques, using magnetic resonance imaging and para-hydrogen (p-H2) polarization, that allow direct visualization of gasphase flow and the density of active catalyst in a packed-bed microreactor, as well as control over the dynamics of the polarized state in space and time to facilitate the study of subsequent reactions.
Journal ArticleDOI
Picomolar sensitivity MRI and photoacoustic imaging of cobalt nanoparticles
Louis-S. Bouchard,M. Sabieh Anwar,Gang Logan Liu,Gang Logan Liu,Byron Hann,Z. Harry Xie,Joe W. Gray,Xueding Wang,Alexander Pines,Alexander Pines,Fanqing Frank Chen,Fanqing Frank Chen,Fanqing Frank Chen +12 more
TL;DR: A unique combination of MRI and photoacoustic tomography to detect picomolar concentrations of nanoparticles in biological tissues, in which MRI provides volume detection, whereas PAT performs edge detection is explored.
Journal ArticleDOI
Machine Learning Approach to RF Transmitter Identification
Khalid Youssef,Louis-S. Bouchard,Karen Zita Haigh,Jan Silovsky,Bishal Thapa,Chris Vander Valk +5 more
TL;DR: This paper investigates the use of machine learning strategies to the classification and identification problem in RF waveforms, and evaluates four different strategies: conventional deep neural nets, convolutional neuralnets, support vector machines, and deep neuralnets with multi-stage training.
