Deep learning with light

Researchers at MIT have developed a new method that uses optics to accelerate machine-learning computations on low-power devices. By encoding model components onto light waves, data can be transmitted rapidly and computations performed quickly, leading to over a hundredfold improvement in energy efficiency.

Calcium content determines the peak intensity ratio due to iron ions at Mössbauer spectra in pyroxene

Researchers at Osaka Metropolitan University used Mössbauer spectroscopy to study monoclinic pyroxenes, a type of calcium-rich mineral. They found that the tensor determining iron ion intensity ratios is independent of iron content but dependent on calcium content.

Infants who die unexpectedly in the first week might have different risk factors than those who die in the first month

A Rutgers study found that infants who died unexpectedly in the first week of life had different risk factors compared to those who died later. The study analyzed data from 2000 to 2015 and found that mothers of infants dying in the first week showed less evidence of common risk factors such as smoking during pregnancy.
