Book Announcement
How biodiversity classification, with its ranking of species, has social and political implications as well as implications for the field of information studies.
Research published in Nature Machine Intelligence illustrates neuromorphic technology is up to sixteen times more energy-efficient for large deep learning networks than other AI systems.
Stating that a system is topological is a sophisticated way of saying that, in the described situation of the pie-like interfaced materials, it is impossible to devise a construction where the number of incoming radiation channels differs from the number of outgoing channels. In other words, in topological systems there is forcibly a balance between the number of incoming channels and the number of outgoing channels, analogous to the conservation of current in Kirchhoff's circuit laws. In fact, if the number of incoming and outgoing channels could be different, then it would be possible to devise an excitation which would continuously transfer energy from a source to the junction point. In such a situation, a thermodynamic equilibrium can be reached only if the energy arriving at the junction is dissipated as heat. Now, as reported in Advanced Photonics, researchers have shown that such a contrived scenario can indeed be observed in realistic physical systems. They explore the fact that nonreciprocal systems with a continuous translation symmetry have an ill-defined topology. They demonstrate that, contrary to common belief, a junction of nonreciprocal materials is not necessarily bound by any balancing constraint on the number of in/out channels.
About The Study: This analysis of nearly 500,000 daytime operations performed by 1,131 surgeons found no significant association between operating the previous night and the incidence of in-hospital death or major complications for daytime operations performed the subsequent day.

People who deny the existence of structural racism are more likely to exhibit anti-Black prejudice and less likely to show racial empathy or openness to diversity, according to research published by the American Psychological Association.
Brain mapping consists in finding the brain regions associated with different traits, such as diseases, cognitive functions, or behaviours, and is a major field of research in neuroscience. This approach is based on statistical models and is subject to numerous biases. To try to counter them, researchers from the ARAMIS team, a joint team between the Paris Brain institute and Inria, and their collaborators at the University of Queensland (Australia) and Westlake University (China), propose a new statistical model for brain mapping. The results are published in the Journal of Medical Imaging
