BackgroundColorectal cancer (CRC) is a malignant tumor originating from the epithelial cells of colon or rectum. Currently, the main treatment strategy is surgery with chemotherapy and radiotherapy, but the 5-year survival rate is only 63%. Therefore, new therapeutic targets should be discovered and...

The existing multi-carrier composite modulation recognition methods have failed to effectively integrate inner and outer modulation characteristics, thereby limiting the potential for improving recognition performance under low signal-to-noise ratio (SNR) conditions. To address this issue, this pape...

Early diagnosis of cancer is crucially important for prescribing a therapy plan to possibly save human lives. Towards this end, one amongst the pathologies is to consider the efficient detection of volatile organic compounds (VOCs) related, for instance, to the pancreatic cancer existing in exhaled...

Recently weakly-coupled mode-division multiplexing (MDM) transmission systems and networks based on ultralow-modal-crosstalk few-mode fiber (FMF) have attracted much interest, for which optical amplification technologies with low modal crosstalk and two-dimension mode-wavelength gain flattening are...

We studied the characteristics of coupled-core four-core fibers (CC-4CFs) with different core pitches both theoretically and experimentally. The spatial mode dispersions of different fibers were analyzed, and the result agrees well with theoretical ones. In the experiment, we achieved a spatial mode...

Ultra-high-speed integrated communication and sensing (ICS) transmission techniques are highly desired for next-generation highly reliable optical transport networks (OTNs). The inherent multiple-channel advantage of uncoupled multi-core fibers (MCFs) empowers the evolution of ICS techniques. In thi...

Tonifying polysaccharides, as a class of natural medicines, have attracted considerable interest due to their low toxicity, high safety profile, and excellent stability. Investigations have highlighted the significant impact of polysaccharides derived from Chinese medicinal herbs on the modulation o...

Background: Omicron had swept the mainland China between December 2022 and January 2023, while SARS-CoV-2 still continued to evolve. To fully prepare for the next wave, it’s urgent to evaluate the humoral immune response post BA.5/BF.7 breakthrough infection against predominant sub-lineages among ex...
