Abstract This study presents an innovative approach to fault diagnosis in sliding bearings, targeting the challenges posed by weak fault signals and heavy noise interference. The proposed method employs a generalized multi-scale permutation entropy (GMPE) algorithm, which utilizes a multi-scale mean...

We apply a machine learning (ML) approach to predict the properties of glass optical diffusers fabricated by ablation-assisted nanosecond laser machining. This ‘indirect’ laser machining utilizes the interaction between the glass substrate and ablated fragments which are produced by nanosecond laser...

Abstract An ultrathin and flexible perovskite solar cell (f‐PSC) is highly desirable as a portable power source, while the rigidity of key components including perovskite and transparent electrode of a device leads to challenges in fabrication. Here, several approaches are developed to improve the m...

With the development of sixth-generation mobile communication technology (6G), ultra-reliable and low latency communication (URLLC) is vital for latency-sensitive applications. User-centric cell-free massive MIMO (CF-mMIMO) architectures meet these demands by removing cell boundaries and ensuring fa...

The identification of glyphosate-tolerant maize genotypes by field spraying with glyphosate is time-consuming, costly and requires treatment of a large area. We report a potentially better technique of seed-soaking to identify glyphosate-tolerant maize genotypes. The effects of soaking maize seeds i...

BackgroundMelanomas are caused by the malignant transformation of melanocytes. Numerous studies have demonstrated that the tyrosol components of salidroside inhibit tyrosinase activity. The PI3K/Akt/mTOR signaling pathway plays a crucial role in biological pigment synthesis. However, how salidroside...

Sustainable detoxification and advanced treatment of toxic organic pollutants (TOPs) in wastewater are essential for water reclamation and ecosystem security. Although biological treatment is a low-carbon and eco-friendly approach for TOPs degradation, its effectiveness is often limited by the high...

Auxin signaling plays a significant role in the whole process of plant growth and development from embryogenesis to senescence. Auxin response factors (ARFs) are reported to regulate the expression of auxin response genes by binding to auxin response elements. ARF is the most critical transcription...

One strain of Toxoplasma gondii was successfully isolated from chickens in China by bioassay in mice. Antibodies and circulating antigens of T. gondii were assayed by the ELISA kits in 100 free range chickens from a rural area surrounding Funing, China. Fifty-three chickens were antibody-positive an...

Chalkiness is one of the most important agronomic traits in rice breeding, which directly affects the quality of rice seed. In this study, we identified a chalkiness endosperm mutant, chalk-h, from N-methyl-N-nitrosourea (MNU)-induced japonica rice cultivar Hwacheong (HC). Compared with wild type (W...

Chalcone synthases (CHS, EC 2.3.1.74) are key enzymes that catalyze the first committed step in flavonoid biosynthesis. In this study, we isolated a chalcone synthase, named NtCHS6, from Nicotiana tabacum. This synthase shared high homology with the NSCHSL (Y14507) gene and contained most of the con...
