Artificial intelligence (AI) edge devices demand high-precision energy-efficient computations, large on-chip model storage, rapid wakeup-to-response time and cost-effective foundry-ready solutions. Floating point (FP) computation provides precision exceeding that of integer (INT) formats at the cost of higher power and storage overhead. Multi-level-cell (MLC) memristor compute-in-memory (CIM) provides compact non-volatile storage and energy-efficient computation but is prone to accuracy loss owing to process variation.

Staining revealed that the CD concentration within cells depended on the characteristic intracellular environment of the species. Therefore, based on the concentration dependence of the CD fluorescence, different bacterial species were specifically labeled.

However, severe inflammation can also produce similar symptoms in cells. In this study, normal, inflammatory, and carcinoma hepatic cells were stained with 4',6-diamidino-2-phenylindole (DAPI) and investigated by hyperspectral microscopy.
View Article and Find Full Text PDFGram stain is one of the most common techniques used to visualize bacteria under microscopy and classify bacteria into two large groups (Gram-positive and Gram-negative). However, such an inaccurate classification is unfavorable for bacterial research. For instance, soil-rhizosphere bacteria, () and () have different effects on plants, nonetheless, they are both Gram-positive and difficult to be differentiated.
