Abstract A bearing fault diagnosis method based on the Markov transition field (MTF) and SEnet (SE)-IShufflenetV2 model is proposed in this paper due to the problems of complex working conditions, low fault diagnosis accuracy, and poor generalization of rolling bearing. Firstly, MTF is used to encode one-dimensional time series vibration signals and convert them into time-dependent and unique two-dimensional feature images. Then, the generated two-dimensional dataset is fed into the SE-IShufflenetV2 model for training to achieve fault feature extraction and classification. This paper selects the bearing fault datasets from Case Western Reserve University and Paderborn University… More >

Abstract Cell-cell adhesions are often subjected to mechanical strains of different rates and magnitudes in normal tissue function and in disease conditions. To date, few strategies exist to directly and quantitatively investigate the effect of mechanical forces exerted by cell-cell adhesions, even less the effect of applied load on the transduction of these forces into biochemical signals. To address this knowledge gap, we designed and fabricated a platform that performs quantitative mechanical characterization of single cell-cell adhesion structures using two photon polymerization of multiple materials [1]. This microsystem provides interrogation and stimulation of cell-cell junctions through… More >

Abstract The 15-carbon terpenoid abscisic acid (ABA) acts in vascular plants as a versatile hormone playing essential roles in reproductive development, vegetative development and growth, stress-development interactions, and physiological responses to abiotic and biotic stresses. Over the past 60 years, ABA dynamics, regulation, and responses have been progressively characterized: synthesis, transport and translocation, conjugation and deconjugation, metabolism, sensing, signal transduction, and downstream responses. In this context, the discovery of ABA exporters and importers has added novel dimensions to the understanding of ABA regulation. Moreover, since the initial discovery of the adenosine triphosphate-binding cassette (ABC) AtABCG25 exporter… More >

Abstract During post-harvest storage of Cucumis sativus fruit, the application of trypsin treatment could increase flavonoid compound levels and reduce oxidative damage. To investigate the mechanism of trypsin-induced flavonoid biosynthesis in C. sativus, we conducted a combined analysis of transcriptomics and widely targeted metabolomics. One hundred and seventy-five significantly different metabolites were obtained from metabolomics data. The kyoto encyclopedia of genes and genomes (KEGG) functional enrichment results indicated that these metabolites were mainly involved in the phenylpropanoid biosynthesis pathway. By combining the results of the weighted gene co-expression network analysis (WGCNA) with the 130 upregulated phenylpropanoid metabolites, 22… More >

Abstract Acer rubrum is an important garden color-leafed plant. Its leaves will turn red in autumn, which is of great ornamental value. The leaf color change in Acer rubrum is closely associated with anthocyanins accumulation. In anthocyanin synthesis and accumulation, various transcription factor families play significant regulatory roles, including the basic (region) leucine zipper (bZIP). However, there is no report on the systematic identification and functional analysis of the bZIPs in Acer rubrum. In this study, 137 bZIPs distributed on 29 chromosomes of Acer rubrum were identified and renamed according to their locations on the chromosomes. According to the constructed… More >

Abstract We have developed a machine learning model, called Hybrid-PINNs (Physics Informed Neural Networks), and applied for fast predictions of transport structures (flow and thermal fields) in the silicon (Si) melt during the Czochralski (Cz) bulk single crystal growth. Si bulk single crystals are mostly grown by the Cz method. For the growth of high-quality Si crystals with this method, it is essential to understand and control these transport structures in the melt. Since the direct observation of such transport fields in the melt during growth is usually impossible, numerical simulations provide a powerful tool for… More >

Abstract A pentagon plate-shaped metamaterial with resonators inside is designed, and both sides are covered with PVC membranes. The components are designed with sloped exterior walls and can form a regular dodecahedron metacage. The effect of the single component is based on the vibration of the membranes, when the size of two membranes has the same size, the transmission loss appears to be significant around 900 Hz and have another peak around 1400 Hz. When use twelve components to form a regular dodecahedron metacage, with a diameter of less than half a meter, a measurement of… More >

Abstract Background: Coping self-efficacy can help individuals mitigate the adverse emotional impacts of stress, anxiety, and other negative emotions, and it also influences individuals’ academic performance, including school adjustment and academic burnout. It is an important factor affecting the mental health of adolescents. However, there is no measurement tool specifically designed for adolescent populations in China. Therefore, the purpose of this study is to assess the applicability of the Coping Self-Efficacy Scale (CSES) among Chinese adolescents. Methods: In September 2023, this study collected data through online questionnaires and ultimately conducted item analysis, exploratory factor analysis, confirmatory… More >

Abstract The study of boundary-layer transition and turbulence plays a crucial role in the development and design of high-speed aircrafts. Direct numerical simulation (DNS) is a numerical tool that enables the capture of flow phenomena across all scales, making it highly valuable for investigating the mechanism and process of transition and turbulence. In the DNS community, the prevailing approach involves directly resolving the Navier-Stokes (NS) equations. However, certain high-order effects lie beyond the capabilities of NS models when simulating compressible transition and turbulence under specific circumstances. To address this limitation, we have developed a DNS method… More >

Abstract By integrating advanced digital technologies such as cloud computing and the Internet of Things in sensor measurement, information communication, and other fields, the digital DC distribution network can efficiently and reliably access Distributed Generator (DG) and Energy Storage Systems (ESS), exhibiting significant advantages in terms of controllability and meeting requirements of Plug-and-Play (PnP) operations. However, during device plug-in and -out processes, improper system parameters may lead to small-signal stability issues. Therefore, before executing PnP operations, conducting stability analysis and adjusting parameters swiftly is crucial.
