Machine learning assisted masking of parasitic signals in Bragg coherent diffraction imaging

open access: yesJournal of Synchrotron Radiation, EarlyView.
Bragg coherent diffraction imaging measurement sometimes requires manual and time‐consuming cleaning of parasitic signals termed `aliens' from nearby particles that can affect the phase retrieval reconstruction. Here, we propose using a clustering technique to speed up this process while keeping the resolution of the reconstructed object high.

Conceptual, Regulatory and Strategic Imperatives in the Early Days of EEG-Based Biomarker Validation for Neurodevelopmental Disabilities

open access: yesFrontiers in Integrative Neuroscience, 2019
Biological treatment development for syndromal neuropsychiatric conditions such as autism has seen slow progress for decades. Speeding drug discovery may result from the judicious development and application of biomarker measures of brain function to ...

HOUSING QUESTION OLD AND NEW: Mapping Crowding, Tenure, Rents and Segregation in the Neighborhoods of Major European Cities around 1900 and Today

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract In a context of unprecedented urbanization, nineteenth‐century European cities faced the ‘housing question’, i.e. precarious housing standards and affordability problems. While existing research has well described these historical housing problems in single‐city studies or in national urbanization histories, to our knowledge, there are hardly ...

Eggshell pigment composition covaries with phylogeny but not with life history or with nesting ecology traits of British passerines [PDF]

open access: yes, 2015
No single hypothesis is likely to explain the diversity in eggshell coloration and patterning across birds, suggesting that eggshell appearance is most likely to have evolved to fulfill many nonexclusive functions.

Real estate agent response to Hispanic/Latino clients: Homophily, local demographic, and regional differences

open access: yesReal Estate Economics, EarlyView.
Abstract We conduct a large‐scale correspondence experiment across 11 US states to assess differential treatment of Hispanic/Latino clients by real estate agents. The experiment covers an area with a wide range of underlying Hispanic/Latino population and a subject pool of agents that is ethnically diverse.

Radiometric absolute noise-temperature measurement system features improved accuracy and calibration ease [PDF]

open access: yes, 1970
Radiometric receiver system, which measures noise temperatures in degrees Kelvin, does not require cryogenic noise sources for routine operation. It eliminates radiometer calibration errors associated with RF attenuation measurements.
