Silicon-Based Metastructure Optical Scattering Multiply-Accumulate Computation Chip.

Optical neural networks (ONN) have become the most promising solution to replacing electronic neural networks, which have the advantages of large bandwidth, low energy consumption, strong parallel processing ability, and super high speed. Silicon-based micro-nano integrated photonic platforms have demonstrated good compatibility with complementary metal oxide semiconductor (CMOS) processing. Therefore, without completely changing the existing silicon-based fabrication technology, optoelectronic hybrid devices or all-optical devices of better performance can be achieved on such platforms.

Design, synthesis and antibacterial evaluation of novel oxazolidinone derivatives nitrogen-containing fused heterocyclic moiety.

A series of novel oxazolidinone derivatives with nitrogen-containing fused heterocyclic moiety were designed and synthesized in this article. Their antibacterial activities were measured against S. aureus, MRSA and MSSA by MIC assay.
