Drawing inspiration from RA, introduces initial distributions irradiated hypothetical spatial above PA to mitigate grating lobes PA. An...
β-elemene has been evidenced to suppress the development of numerous cancers including lung cancer. Previous research found that in A549 cells, increased expression adenosine monophosphate-activated protein kinase (AMPK) α (AMPKα), which negatively regulates Warburg effect. Bioinformatics predicted binding sites exist between AMPKα and miR-301a-3p, an miRNA shown oncogenic function many cancers. The aim this work was investigate effect on non-small-cell cancer (NSCLC) cells its mechanism....
In this paper, the differences in reflection coefficient performance when different liquids are used to design liquid ground have been discussed. According theoretical analysis and simulation results, water may be a better choice for designing transparent ground. On basis, new type of fully frequency polarization reconfigurable antenna is proposed. The entire antenna, except feeding structure, has high transparency performance, making it optical stealth more application scenarios....
Ischemic stroke (IS) is a leading cause of long-term disability and even mortality, threatening people's lives. Yinao Fujian (YNFJ) formula Traditional Chinese Medicine that has been widely used to treat patients with IS. However, the molecular mechanism YNFJ for treatment IS still elusive. Our study aimed explore potential protective effect underlying mechanisms on using network pharmacology approach coupled experimental validation.
Histopathological whole slide image (WSI) analysis with deep learning has become a research focus in computational pathology. The current paradigm is mainly based on multiple instance (MIL), which approaches Transformer as the backbone are well discussed. These methods convert WSI tasks into sequence by representing patches tokens sequence. However, feature complexity brought high heterogeneity and ultra-long sequences gigapixel size makes Transformer-based MIL suffer from challenges of...
