Revolutionary algorithm optimizes nuclear reactor radiation shielding design
Nuclear Science and TechniquesPeer-Reviewed Publication
The research team (NEAL) at the University of South China has proposed an innovative radiation-shielding optimization method based on a reference-point-selection strategy. This method has been successfully applied to the optimization of radiation-shielding designs for nuclear reactors. By integrating genetic algorithms with artificial bee colony algorithms, the method substantially improves the lightweight, compact, and radiation protection performance of shielding structures, thereby providing vital technical support for the design of nuclear reactors.The research team (NEAL) at the University of South China has proposed an innovative radiation-shielding optimization method based on a reference-point-selection strategy.

So, our city’s shrinking—Now what?
Osaka Metropolitan UniversityPeer-Reviewed Publication
An Osaka Metropolitan University researcher examined the nonlinear multidimensional factors that correlate with population changes according to city size. The results indicate that population changes correlated with welfare expenditures in small and medium-sized cities.

Deepfakes now come with a realistic heartbeat, making them harder to unmask
FrontiersPeer-Reviewed Publication
Current algorithms for the detection of deepfakes increasingly rely on remote pulse reading to distinguish them from genuine videos of people. Here, scientists show for the first time that the most recent deepfakes feature a global pulse rate which appears realistic. This worrying development makes it necessary for deepfake detectors to become more powerful, for example, by focusing on local variations in blood flow within the face.
