150 years of the geography of innovation
(Elsevier, 2021-01-25)Innovation has long been seen as central to long-term regional growth. Due to the absence of comprehensive data on the geography of innovation covering long time periods, quantifying long-term innovation-development linkages ... -
A 1D fluid model of the Centaurus A jet
(2018-09-27)We implement a steady, one-dimensional flow model for the X-ray jet of Centaurus A in which entrainment of stellar mass loss is the primary cause of dissipation. Using over 260 ks of new and archival Chandra/ACIS data, we ... -
2 mm GISMO Observations of the Galactic Center. I. Dust Emission
(The American Astronomical Society, 2019-11-01)The Central Molecular Zone (CMZ), covering the inner ∼ 1 ◦ of the Galactic plane has been mapped at 2 mm using the GISMO bolometric camera on the 30 m IRAM telescope. The 2100 resolution maps show abundant emission from ... -
2 mm GISMO Observations of the Galactic Center. II. A Nonthermal Filament in the Radio Arc and Compact Sources
(The American Astronomical Society, 2019-11-01)We have used the Goddard IRAM 2-Millimeter Observer (GISMO) with the 30 m IRAM telescope to carry out a 2 mm survey of the Galaxy’s central molecular zone (CMZ). These observations detect thermal emission from cold ISM ... -
The 2001 Superoutburst of WZ Sagittae
(IOP, 2002-06-10)We report the results of a worldwide campaign to observe WZ Sagittae during its 2001 superoutburst. After a 23 yr slumber at V = 15.5, the star rose within 2 days to a peak brightness of 8.2, and showed a main eruption ... -
2012 Laird Fellow
(University of Delaware, 2012-06-01)The prestigious fellowship honors the memory of George W. Laird, a UD mechanical engineering graduate who died in an accident at the age of 35. Given since 1997, it is bestowed upon candidates who exhibit character, ... -
2021 Roadmap on Neuromorphic Computing and Engineering
(IOP Publishing, 2021-05-12)Modern computation based on the von Neumann architecture is today a mature cutting-edge science. In this architecture, processing and memory units are implemented as separate blocks interchanging data intensively and ... -
2FHL: THE SECOND CATALOG OF HARD FERMI-LAT SOURCES
(IOP, 2016-01-14)We present a catalog of sources detected above 50 GeV by the Fermi-Large Area Telescope (LAT) in 80 months of data. The newly delivered Pass 8 event-level analysis allows the detection and characterization of sources in ... -

32-year record-high surface melt in 2019/2020 on north George VI Ice Shelf, Antarctic Peninsula
(Copernicus Publications, 2020-10-22)In the 2019/2020 austral summer, the surface melt duration and extent on the northern George VI Ice Shelf (GVIIS) was exceptional compared to the 31 previous summers of dramatically lower melt. This finding is based on ... -
3D Path-Following using MRAC on a Millimeter-Scale Spiral-Type Magnetic Robot
(IEEE, 2020-01-24)This paper focuses on the 3D path-following of a spiral-type helical magnetic swimmer in a water-filled workspace. The swimmer has a diameter of 2.5 mm, a length of 6 mm, and is controlled by an external time-varying ... -
3D Space-Time Adaptive Hybrid Simulations of Magnetosheath High-Speed Jets
(American Geophysical Union, 2021-06-18)Abstract We study the generation and evolution of spatially localized dynamic plasma pressure enhancements in the magnetosheath (high-speed jets) by carrying out three-dimensional hybrid simulations of the Earth's dayside ... -
3D-Printed Microfluidic Devices for Enhanced Online Sampling and Direct Optical Measurements
(ACS Publications, 2020-05-03)3D printing has emerged as a robust technique to fabricate reliable and reproducible microfluidic devices. However, a limitation of 3D-printed devices has been the low transparency even when printed in a “clear” material. ... -
A 3D-Printed, Modular, and Parallelized Microfluidic System with Customizable ECM Integration to Investigate the Roles of Basement Membrane Topography on Endothelial Cells
(2021-02-05)Because dysfunctions of endothelial cells are involved in many pathologies, in vitro endothelial cell models for pathophysiological and pharmaceutical studies have been a valuable research tool. Although numerous ... -
3FGL DEMOGRAPHICS OUTSIDE THE GALACTIC PLANE USING SUPERVISED MACHINE LEARNING: PULSAR AND DARK MATTER SUBHALO INTERPRETATIONS
