基于马赫-曾德尔干涉仪(Mach-Zehnder Interferometer,MZI)级联拓扑结构的线性光学处理器被证明是实现光学神经网络(Optical Neural Network,ONN)的重要途径,但还有不少实际问题有待解决。针对芯片制造、测试过程中可能导致的相位误差和插入损耗等问题,通过实验和理论仿真分析了几种基于MZI结构的可重构光学处理器。发现可以通过单个N×N的Clements阵列结构来实现任意酉矩阵的权重,构建稀疏连接的全复值光学神经网络,将光学深度大大降低,以实现较高的插入损耗鲁棒性。此外,对于多层光学神经网络来说,由于构建该任意酉矩阵的自由度有限,故在每一层Clements结构前面加一个相移器层,有助于将分类数据映射到更高的数据维度,能使神经网络更快速的收敛。

Intestinal macrophages play crucial roles in both intestinal inflammation and immune homeostasis. They can adopt two distinct phenotypes, primarily determined by environmental cues. These phenotypes encompass the classically activated pro-inflammatory M1 phenotype, as well as the alternatively activated anti-inflammatory M2.phenotype. In regular conditions, intestinal macrophages serve to shield the gut from inflammatory harm. However, when a combination of genetic and environmental elements influences the polarization of these macrophages, it can result in an M1/M2.macrophage activation imbalance, subsequently leading to a loss of control over intestinal inflammation. This shift transforms normal inflammatory responses into pathological damage within the intestines. In patients with ulcerative colitis-associated colorectal cancer (UC-CRC), disorders related to intestinal inflammation are closely correlated with an imbalance in the polarization of intestinal M1/M2.macrophages. Therefore, reinstating the equilibrium in M1/M2.macrophage polarization could potentially serve as an effective approach to the prevention and treatment of UC-CRC. This paper aims to scrutinize the clinical evidence regarding Chinese medicine (CM) in the treatment of UC-CRC, the pivotal role of macrophage polarization in UC-CRC pathogenesis, and the potential mechanisms through which CM regulates macrophage polarization to address UC-CRC. Our objective is to offer fresh perspectives for clinical application, fundamental research, and pharmaceutical advancement in UC-CRC.
