AbstractSuperconducting (SC) states that break space-group symmetries of the underlying crystal can exhibit nontrivial spatial modulation of the order parameter. Previously, such states were intimately associated with the breaking of translational symmetry1,2, resulting in the density-wave orders3,4,5,6,7,8, with wavelengths spanning several unit cells9,10,11,12,13,14,15,16,17,18,19.

This study develops an artificial intelligence model to quickly and easily determine correct mask-wearing in real time using thermal videos that ascertained temperature changes caused by air trapped inside the mask. Five types of masks approved by the Korean Ministry of Food and Drug Safety were worn in four different ways across 50 participants, generating 5000 videos. The results showed that 3DCNN outperformed ConvLSTM in both binary and multi-classification for mask wearing methods, with the highest AUROC of 0.986 for multi-classification. Each mask type scored AUROC values > 0.9, with KF-AD being the best classified. This improved use of thermal imaging and deep learning for mask fit-checking could be useful in high-risk environments. It can be applied to various mask types, which enables easy generalizability and advantages in public and occupational health and healthcare system.
Woo Hannah Brings ‘The Great Ballroom’ to Frieze Seoul

Sep 5, 2023 | frieze.com | Hyunjin Kim

Fabric is a familiar material to the artist Woo Hannah. It has given rise to irrepressible stories of chaotic and campy creatures. It has created a space where her myriad emotions combat one another. This space has also been generous, where desires and mutant imaginaries have relentlessly thrived. In lieu of traditional or organic materials, Woo uses synthetic fibres that are either shiny, gooey, bouncy, electronic and psychedelic, or thin, crunchy and plastic.
