Summary: Most studies on WC-based cermet coatings have focused on their erosion, corrosion, and wear resistance. However, there is limited research on the effect of WC-based cermet coatings on the mechanical properties of the coating system. In this study, a WC-10Co4Cr coating was prepared using High-Velocity Oxygen Fuel technology (HVOF) on AISI 4135 steel substrate, and the tensile and fatigue properties of the HVOF-sprayed WC-10Co4Cr coating system were investigated. The results showed that the WC-10Co4Cr coating degraded the tensile properties of the coating system, with a more noticeable effect observed with thicker coatings. Additionally, the fatigue life of the coating system decreased under different loads when sprayed with WC-10Co4Cr coating.

Summary: In this article, an intelligent feedforward prediction and compensation scheme combined with a dual-loop high-bandwidth controller is proposed for high-speed and high-precision tracking controls of a nanopositioning stage. The dual-loop controller, consisting of an inner loop damping and an outer loop tracking controller, is developed with optimized parameters to provide a control bandwidth over the first resonant frequency of the stage. The effectiveness of the intelligent tracking error prediction method and the excellent performance of the control strategy for high-precision tracking of high-frequency reference trajectories are validated through experimental investigations on a self-made piezoelectric-actuated stage.

Summary: Continuous plant growth relies on cell division and elongation, which is regulated by brassinosteroids (BR). In this study, the researchers used cotton fiber to investigate cell-specific BR signaling and found that the transcriptional activator GhBES1 promotes fiber elongation by activating GhCERP, a protein related to cell elongation. GhCERP then transmits the BR signal to its target gene GhEXPA3-1, which ultimately promotes fiber cell elongation. Furthermore, the BR-mediated BES1-CERP-EXPA3 signaling cascade also promotes root and hypocotyl growth in Arabidopsis, indicating its broad significance in regulating BR-promoted cell elongation.

Summary: This work proposes a new spherical-orthogonal-symmetric Haar wavelet for decomposing and reconstructing spherical iris signals, aiming to obtain stronger geometric features of iris surface. The proposed wavelet is compared with spherical harmonics, semi-orthogonal, and nearly orthogonal spherical Haar wavelets in terms of feature extraction abilities. The results show that the developed spherical-orthogonal-symmetric Haar wavelet, when combined with a convolutional neural network, has a stronger iris recognition ability compared to the other wavelet bases.

Summary: We conducted the first multi-color light curves analysis of the eclipsing binary V2769 Ori. The photometric solution using the Wilson-Devinney method revealed that V2769 Ori is a deep, low-mass-ratio contact binary with a reliable contact degree and mass ratio. We constructed and analyzed the O-C diagram and found a long-term period decrease and a periodic oscillation. The period decrease can be attributed to mass transfer and angular momentum loss, while the periodic oscillation may be caused by the light-travel time effect.

Summary: Mimicking brain perceptual processing and using biocompatible and biodegradable materials in neuromorphic devices are both important for the design of bionic intelligent systems. In this study, a gelatin/carboxylated chitosan composite electrolyte film was used as the gate dielectric in oxide neuromorphic transistors, successfully mimicking synaptic plasticity. A quantitative processing method for tactile recognition based on spike number dependent synaptic plasticity was proposed, and an artificial neural network achieved a recognition accuracy of over 90% for MNIST handwritten digits. The results show that the proposed GEL/C-CS gated neuromorphic device has promising application potential in the design of bionic intelligent systems and brain-inspired neuromorphic systems.

Summary: This paper proposes a general parametric repetitive control (GPRC) method based on the IIR filter to address the limitations of repetitive control in terms of sensitivity to frequency shift and undesired gain amplification. By analyzing its sensitivity function, it is found that the design of GPRC can be converted to the explicit parametric design of an IIR high pass filter. Comparative experiments show that GPRC exhibits excellent robustness against frequency shift and advanced performance at the aperiodic frequencies.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist. In this study, researchers developed an interpenetrating Janus wettability stent coating that enables unidirectional draining of excessive biofluid. They also demonstrated directional biofluid movement using a self-pumping dressing with potential applications in biofluid collection and disease diagnosis through metal ion detection. This integrated system presents an opportunity for designing wound dressings with effective biofluid management and metal ion detection capabilities.
