MAGNETIC BRANEWORLDS: COSMOLOGY AND WORMHOLES

Magnetic braneworlds: cosmology and wormholes

Abstract We construct 4D flat Big Bang-Big Crunch cosmologies and Anti-de Sitter (AdS) planar eternally traversable wormholes using braneworlds embedded in asymptotically AdS5 spacetimes.The background geometries are the AdS5 magnetic black brane and the magnetically charged AdS5 soliton, respectively.The two setups arise from different analytic co

Occupational health strategies and insights for elderly workers in Japan and South Korea in the context of declining birth rates and aging populations

China has a large, advanced, and rapidly aging population, coupled with a trend of decreasing birth rates that is exacerbating the issue of an aging society.It is expected that by 2030, China will become a hyper-aged society.As the demographic dividend gradually diminishes, the working-age population is shrinking in size and becoming increasingly o

Hessian-regularized co-training for social activity recognition.

Co-training is a major multi-view learning paradigm that alternately trains two classifiers on two distinct views and maximizes the mutual agreement on the two-view unlabeled data.Traditional co-training algorithms usually train a learner on each view separately and then force the learners to be consistent across views.Although many co-trainings ha
