Background— Although the value of coronary artery calcium (CAC) for atherosclerosis screening is gaining acceptance, its efficacy in predicting flow-limiting disease remains controversial, and incremental prognostic over myocardial perfusion not well established. Methods Results— We evaluated 695 consecutive intermediate-risk patients undergoing combined rest-stress rubidium 82 positron emission tomography (PET) imaging CAC scoring on a hybrid PET-computed (CT) scanner. The frequency...
We present a new determination of the ultraviolet (UV) galaxy luminosity function (LF) at redshift z ≃ 7 and 8, first estimate 9. An accurate form evolution LF during this era is key importance for improving our knowledge earliest phases process cosmic reionization. Our analysis exploits to full new, deepest Wide Field Camera 3/infrared imaging from Hubble Space Telescope (HST) Ultra-Deep 2012 (UDF12) campaign, with dynamic range provided by including consistent all appropriate,...
We present Keck/MOSFIRE observations of UV metal lines in four bright gravitationally-lensed z~6-8 galaxies behind the cluster Abell 1703. The spectrum A1703-zd6, a highly-magnified star forming galaxy with Lyman-alpha redshift z=7.045, reveals confident detection nebular CIV emission line (unresolved FWHM < 125 km/s). are not detected three other galaxies. At z~2-3, is observed just 1% UV-selected presence strong one small sample targeted this paper may indicate hard ionizing spectra more...
Deep spectroscopic observations of z ≳ 6.5 galaxies have revealed a marked decline with increasing redshift in the detectability Ly α emission. While this may offer valuable insight into end reionization process, it presents challenge to detailed study bright photometrically-selected distant sources now being found via deep Hubble Space Telescope imaging, and particularly those highly magnified viewed through foreground lensing clusters. In paper, we demonstrate validity new way forward...
Observations of H$_2$O masers from circumnuclear disks in active galaxies for the Megamaser Cosmology Project allow accurate measurement mass supermassive black holes (BH) these galaxies. We present Very Long Baseline Interferometry (VLBI) images and kinematics water maser emission six galaxies: NGC~1194, NGC~2273, NGC~2960 (Mrk~1419), NGC~4388, NGC~6264 NGC~6323. use Keplerian rotation curves megamaser galaxies, plus a seventh previously published, to determine enclosed masses within...
We present the results of a photometric redshift analysis designed to identify z>6 galaxies from near-IR HST imaging in three deep fields (HUDF, HUDF09-2 & ERS). By adopting rigorous set criteria for rejecting low-z interlopers, and by employing deconfusion technique allow available IRAC be included candidate selection process, we have derived robust sample 70 Lyman-break (LBGs) spanning range 6.0<z<8.7. Based on our final investigate distribution UV spectral slopes (beta), finding...
Interventions designed to limit the spread of coronavirus disease 2019 (COVID-19) are having profound effects on delivery health care, but data showing impact oncology clinical trial enrollment, treatment, and monitoring limited. We prospectively tracked relevant from trials at Dana-Farber Cancer Institute January 1, 2018, June 30, 2020, including number open trials, new patient enrollments, in-person virtual visits, dispensed investigational infusions, or shipped oral agents, research...
We report the results of a study exploring stellar populations 13 luminous (L > 1.2L*), spectroscopically confirmed, galaxies in redshift interval 5.5 < z 6.5, all with Hubble Space Telescope (HST) Wide Field Camera 3/infrared and Spitzer Infrared Array imaging from HST/Cosmic Assembly Near-infrared Deep Survey Extended Survey. Based on fitting observed photometry galaxy spectral energy distribution (SED) templates covering wide range different star formation histories, including...
The purpose of these guidelines is to recommend appropriate imaging for patients with blunt chest trauma. These are most often imaged in the emergency room, and thus radiologists play a substantial role prompt, accurate diagnoses that, turn, can lead life-saving interventions.
