Depth and Transient Imaging with Compressive SPAD Array Cameras [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2018 Time-of-flight depth imaging and transient imaging are two imaging modalities that have recently received a lot of interest. Despite much research, existing hardware systems are limited either in terms of temporal resolution or are prohibitively expensive.

Angewandte Chemie, EarlyView.Shewanella oneidensis and Bacillus subtilis, both harboring prophages, reveal a novel biosynthetic route to scalable and programmable DNA superstructures in flower‐ and wire‐like shapes, respectively. Activation of prophages is achieved via 3‐hour starvation and monitored using reporter strains.
