本文提出了基于耦合腔的一维晶格理论方案,其中每个晶胞包含微波腔光子和磁子,通过调控磁子与微波光子的耦合来研究系统中的拓扑相变和拓扑量子通道.首先,分析了在奇偶晶格数情况下,系统能谱和边缘态的特征,并发现边缘态分布可以展示反转过程,可以实现多通道拓扑量子态传输;其次,考虑存在缺陷和无序的扰动,发现它们在较小值范围内,可以使能带产生波动和翻转现象,但边缘状态对其是鲁棒的,这表明边缘态受到系统的拓扑保护.该研究结果为研究拓扑磁子-光子提供了一条新途径,将在量子信息处理中有着广阔的应用前景.

Hypoxic-ischemic encephalopathy (HIE) is a prominent cause of neuronal damage and neonatal death， and effective treatment strategies remain limited. In a prior investigation， we purified a novel peptide (designated MIP-15) from the rare mushroom Morchella importuna， demonstrating its notable free radical scavenging activity. Nevertheless， the potential neuroprotective role of MIP-15 in neonatal hypoxic-ischemic brain damage (HIBD) and its underlying mechanism remain elusive. The purpose of this study was to evaluate whether MIP-15 exerts neuroprotective effects by inhibiting the mitochondrial apoptotic pathway after HIBD. A HIBD model in 7-day-old (P7) rats was established by the Rice–Vannucci method to evaluate the effect of MIP-15 on the neurological damage severity and space cognitive ability of rats. Subsequently， an oxygen glucose deprivation/reoxygenation (OGD/R) model was established in rat primary hippocampal neurons to explore the mechanism of MIP-15 action. Both in vivo and in vitro data showed that MIP-15 markedly restored endogenous antioxidative activity， decreased brain water content， and ameliorated pathological abnormalities following HIBD. The spatial cognitive ability and motor function of HIBD rats were also repaired. Moreover， in primary hippocampal neurons after OGD/R， MIP-15 increased cell viability by inhibiting the mitochondrial-dependent apoptosis pathway， as manifested by stabilization of the mitochondrial membrane potential， prevention of the release of cytochrome c， upregulation of Bcl-2/Bax， and reduction in the triggering of caspase proteins. These data indicate that MIP-15 may have the potential to act as a neuroprotective agent.

A memristor crossbar array (MCA) has emerged as a cutting-edge platform for advanced memory and neuromorphic computing hardware,offering unrivaled bit-level storage density.A diffusive memristor cell (DMC) is particularly well-suited for MCA integration due to its inherent threshold switching characteristics as a selector,effectively addressing current sneak path *** DMC's potential is acknowledged,it necessitates furtherexploration of their practical applicability.
