    • Accelerating self-consistent field convergence with the augmented Roothaan-Hall energy function. 

      Hu, Xiangqian; Yang, Weitao (J Chem Phys, 2010-02-07)
      Based on Pulay's direct inversion iterative subspace (DIIS) approach, we present a method to accelerate self-consistent field (SCF) convergence. In this method, the quadratic augmented Roothaan-Hall (ARH) energy function, ...

    • Amygdala volume changes in posttraumatic stress disorder in a large case-controlled veterans group. 

      Morey, Rajendra A; Gold, Andrea L; LaBar, Kevin S; Beall, Shannon K; Brown, Vanessa M; Haswell, Courtney C; Nasser, Jessica D; ... (10 authors) (Arch Gen Psychiatry, 2012-11)
      CONTEXT: Smaller hippocampal volumes are well established in posttraumatic stress disorder (PTSD), but the relatively few studies of amygdala volume in PTSD have produced equivocal results. OBJECTIVE: To assess a large cohort ...

    • Coded aperture compressive temporal imaging. 

      Llull, Patrick; Liao, Xuejun; Yuan, Xin; Yang, Jianbo; Kittle, David; Carin, Lawrence; Sapiro, Guillermo; ... (8 authors) (Opt Express, 2013-05-06)
      We use mechanical translation of a coded aperture for code division multiple access compression of video. We discuss the compressed video's temporal resolution and present experimental results for reconstructions of > 10 ...

    • Dynamic neural networks supporting memory retrieval. 

      St Jacques, Peggy L; Kragel, Philip A; Rubin, David C (Neuroimage, 2011-07-15)
      How do separate neural networks interact to support complex cognitive processes such as remembrance of the personal past? Autobiographical memory (AM) retrieval recruits a consistent pattern of activation that potentially ...

    • In vivo guidance and assessment of liver radio-frequency ablation with acoustic radiation force elastography. 

      Fahey, Brian J; Nelson, Rendon C; Hsu, Stephen J; Bradway, David P; Dumont, Douglas M; Trahey, Gregg E (Ultrasound Med Biol, 2008-10)
      The initial results from clinical trials investigating the utility of acoustic radiation force impulse (ARFI) imaging for use with radio-frequency ablation (RFA) procedures in the liver are presented. To date, data have ...

    • Intracardiac acoustic radiation force impulse (ARFI) and shear wave imaging in pigs with focal infarctions. 

      Hollender, Peter; Bradway, David; Wolf, Patrick; Goswami, Robi; Trahey, Gregg (IEEE Trans Ultrason Ferroelectr Freq Control, 2013-08)
      Four pigs, three with focal infarctions in the apical intraventricular septum (IVS) and/or left ventricular free wall (LVFW), were imaged with an intracardiac echocardiography (ICE) transducer. Custom beam sequences were ...

    • Photon-counting cine-cardiac CT in the mouse. 

      Clark, Darin P; Holbrook, Matthew; Lee, Chang-Lung; Badea, Cristian T (PloS one, 2019-01)
      The maturation of photon-counting detector (PCD) technology promises to enhance routine CT imaging applications with high-fidelity spectral information. In this paper, we demonstrate the power of this synergy and ...

    • The QIBA Profile for FDG PET/CT as an Imaging Biomarker Measuring Response to Cancer Therapy. 

      Kinahan, Paul E; Perlman, Eric S; Sunderland, John J; Subramaniam, Rathan; Subramaniam, Rathan; Wollenweber, Scott D; Turkington, Timothy G; ... (11 authors) (Radiology, 2020-03)
      The Quantitative Imaging Biomarkers Alliance (QIBA) Profile for fluorodeoxyglucose (FDG) PET/CT imaging was created by QIBA to both characterize and reduce the variability of standardized uptake values (SUVs). The Profile ...
