Abstract: Nonnegative matrix factorization (NMF) becomes tractable in polynomial time with unique solution under separability assumption, which postulates all the data points are contained in the ...

Many diverse applications rely on lithography at the nanoscale, including semiconductor devices, biological probes, solar energy harvesting, spectroscopy and smart materials. The critical dimensions ...

Fibroblast-collagen matrix culture has facilitated the analysis of cell physiology under conditions that more closely resemble an in vivo-like environment compared to conventional 2-dimensional (2D) ...
