The 04 – 10 September 2017 Sun–Earth Connection Events: Solar Flares, Coronal Mass Ejections/Magnetic Clouds, and Geomagnetic Storms
(Springer Netherlands, 2019-08-23)In early September 2017, a series of solar flares and coronal mass ejections (CMEs) erupted from the Sun. The Cor2a coronagraph, a unit of the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI), onboard ... -
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 ... -

4 pillars of college success in science
(TED Conferences, LLC, 2013-02)At age 12, Freeman Hrabowski marched with Martin Luther King. Now he's president of the University of Maryland, Baltimore County (UMBC), where he works to create an environment that helps under-represented students -- ... -
A 4‐year zonal climatology of lower tropospheric CO₂ derived from ocean‐only Atmospheric Infrared Sounder observations
(American Geophysical Union, 2008-09-20)A 4‐year zonally averaged climatology of atmospheric CO₂, ocean only, between ±60° latitude has been derived from the Atmospheric Infrared Sounder (AIRS) radiances. Using only very clear fields of view, the CO₂ profile in ... -

AARPA: Combining Mobile and Power-line Sensing for Fine-grained Appliance Usage and Energy Monitoring
(IEEE, 2015-09-14)To promote energy-efficient operations in residential and office buildings, non-intrusive load monitoring (NILM) techniques have been proposed to infer the fine-grained power consumption and usage patterns of appliances ... -
Academic Socialization in the Homes of Black and Latino Preschool Children: Research Findings and Future Directions
(Springer International Publishing, 2018)This chapter provides an overview of what is known about how Black and Latino families prepare their young children for school and what remains to be understood. It provides a synthesis of research presented in this volume, ... -
Accelerating a climate physics model with OpenCL
(IEEE, 2011-07-19)Open Computing Language (OpenCL) is fast becoming the standard for heterogeneous parallel com- puting. It is designed to run on CPUs, GPUs, and other accelerator architectures. By implementing a real- world application, a ... -
Acceptance of a speech interface for biomedical data collection.
(1997)Speech interfaces have the potential to address the data entry bottleneck of many applications in the field of medical informatics. An experimental study evaluated the effect of perceptual structure on a multimodal speech ... -
The Accretion History of AGN: A Newly Defined Population of Cold Quasars
(2019-08-15)Quasars are the most luminous of active galactic nuclei (AGN), and are perhaps responsible for quenching star formation in their hosts. The Stripe 82X catalog covers 31.3 deg² of the Stripe 82 field, of which the 15.6 deg² ... -
The Acidity of Atmospheric Particles and Clouds
(EGU, 2019-10-18)Acidity, defined as pH, is a central component of aqueous chemistry. In the atmosphere, the acidity of condensed phases (aerosol particles, cloud water, and fog droplets) governs the phase partitioning of semi-volatile ... -
ACM HotMobile 2013 Poster: An Energy Efficient Semantic Context Model for Managing Privacy on Smartphones
(ACM, 2013-07-01)Modern smartphones are capable of gathering massive amounts of data about a user and her context. While this data is mostly utilized for providing services that are better suited to the user, user data and context leakage ... -
Acquiring Forensic Evidence from Infrastructure-as-a-Service Cloud Computing: Exploring and Evaluating Tools, Trust, and Techniques
(2012-08-06)We expose and explore technical and trust issues that arise in acquiring forensic evidence from infrastructure-as-aservice cloud computing and analyze some strategies for addressing these challenges. First, we create a ... -
Active Learning Enabled Activity Recognition
(IEEE, 2016-04-21)Activity recognition in smart environment has been investigated rigorously in recent years. Researchers are enhancing the underlying activity discovery and recognition process by adding various dimensions and functionalities. ... -
Active Solidarity: Intersectional Solidarity in Action
(Oxford University Press, 2019-10-19)While solidarity lies at the heart of collective action, it is not easily achieved. Social movements are characterized not only by difference within activist ranks but also by power asymmetries that reflect broader domination ... -
An active transcoding proxy to support mobile web access
(IEEE, 1998-10-24)In this paper, we present a proxy based system (MOWSER) to support web browsing from mobile clients over wireless networks. Mowser is a proxy agent between the mobile host and the web server, which performs active transcoding ...
