Article Abstract
The rapid advancement of artificial intelligence has facilitated the broad application of machine vision systems in diverse industries. However, these systems are often confronted with computational challenges stemming from an overwhelming amount of data. Here, we have developed a novel optoelectronic memristor synapse constructed from an ITO/Nb:SrTiO heterostructure, which synergistically integrates light signal detection with information processing and memory functions. Notably, we have achieved precise decoupling of the interactions between light power and wavelength at the hardware level, significantly enhancing the accuracy and efficiency of image processing. Furthermore, by incorporating an attention mechanism analogous to that of human vision, we have enabled the device to weight key information and filter out irrelevant data. Experimental results demonstrate that this attention mechanism can increase the accuracy of facial recognition by 13% while reducing the data load by 35-65%. This work is expected to advance the development of optoelectronic synapses in machine vision.

Traumatic brain injury (TBI) impairs attention and executive function, often through disrupted coordination between cognitive and autonomic systems. While electroencephalography (EEG) and pupillometry are widely used to assess neural and autonomic responses independently, little is known about how these systems interact in TBI. Understanding their coordination is essential to identify compensatory mechanisms that may support attention under conditions of neural inefficiency.

Punicalagin, a polyphenolic compound extracted from pomegranate peel, has received increasing attention in recent years due to its antibacterial and antiviral properties. Punicalagin is capable of inhibiting bacterial growth at sub-inhibitory concentrations by affecting cell membrane formation, disrupting membrane integrity, altering cell permeability, affecting efflux pumps, interfering with quorum sensing and influencing virulence factors. Additionally, punicalagin inhibits viruses by modulating enzyme activity, interacting with viral surface proteins, affecting gene expression, blocking viral attachment, disrupting virus receptor interaction and inhibiting viral replication.

Distraction osteogenesis (DO) is an endogenous bone tissue engineering technique that harnesses the regenerative potential of bone and has been widely applied in limb lengthening, bone defect repair, and craniofacial reconstruction. The DO procedure consists of three distinct phases: the latency phase, the distraction phase, and the consolidation phase, each characterized by unique biological processes. In recent years, increasing attention has been directed toward the role of the immune system during DO.

The emergence of the Novel COVID-19 Pandemic has undoubtedly impacted the lives of individuals across the globe. It has drawn the attention of major public health agencies as they work intensely towards understanding the behavior of the virus causing the disease, while simultaneously establishing ways to curb the spread of the virus among populations. As of the time of writing, 7,949,973 confirmed cases have been reported globally; with the United States (US) contributing to 26.

Waterborne viruses have caused outbreaks of related diseases and threaten human health, and advanced oxidation processes (AOPs), as clean and efficient technologies, have received widespread attention for their excellent performance in inactivating viruses. However, heterogeneity in susceptibility of structurally distinct viruses to various reactive oxygen species (ROS) is unclear. This study first measured the heterogeneity in inactivation kinetics and biological mechanisms of four typical viral surrogates (MS2, phi6, phix174, and T4) to various ROS by visible light catalysis.
