Context is ev ... well, something, anyway

Today, computers can't reliably identify the objects in digital images. But if they could, they could comb through hours of video for the two or three minutes that a viewer might be interested in, or perform web searches ...

Quantum-enhanced non-interferometric quantitative phase imaging

Optical phase retrieval and imaging appear in a wide variety of science fields, such as imaging of quasi-transparent biological samples or nanostructures metrological characterization, for example, in the semiconductor industry. ...

Gun ownership and homicide in the US: A stronger correlation

In 2017, there were nearly 40,000 gun-related deaths in the United States, including homicides and suicides. To delve into this alarming statistic, U.S.-trained Université de Montréal economist Karim Chalak and his coauthors ...
