    Abstract Connective tissue attaches to bone across an insertion with spatial gradients in components, microstructure, and biomechanics. Due to regional stress concentrations between two mechanically dissimilar materials, the insertion is vulnerable to mechanical damage during joint movements and difficult to repair completely, which remains a significant clinical challenge. Despite interface stress concentrations, the native insertion physiologically functions as the effective load-transfer device between soft tissue and bone. This review summarizes tendon, ligament, and meniscus insertions cross-sectionally, which is novel in this field. Herein, the similarities and differences between the three kinds of insertions in terms of components, microstructure, and biomechanics are compared in great detail. This review begins with describing the basic components existing in the four zones (original soft tissue, uncalcified fibrocartilage, calcified fibrocartilage, and bone) of each kind of insertion, respectively. It then discusses the microstructure constructed from collagen, glycosaminoglycans (GAGs), minerals and others, which provides key support for the biomechanical properties and affects its physiological functions. Finally, the review continues by describing variations in mechanical properties at the millimeter, micrometer, and nanometer scale, which minimize stress concentrations and control stretch at the insertion. In summary, investigating the contrasts between the three has enlightening significance for future directions of repair strategies of insertion diseases and for bioinspired approaches to effective soft-hard interfaces and other tough and robust materials in medicine and engineering.

    Abstract Abstract Environmental changes and ground subsidence along railway lines are serious concerns during high-speed railway operations. It is worth noting that AutoRegressive Integrated Moving Average (ARMA), Long Short-Term Memory (LSTM), and other prediction methods may present limitations when applied to predict InSAR time series results. To address this issue, this study proposes a prediction method that decomposes the nonlinear settlement time series of feature points obtained through InSAR technology using Ensemble Empirical Mode Decomposition (EEMD). Subsequently, multiple Intrinsic Mode Functions (IMFs) are generated, and each IMF is individually predicted using the Prophet forecasting model. Finally, we employ an equal-weight superimposition method to combine the results, resulting in the prediction of the InSAR settlement time series. The predicted values of each component are subsequently weighted equally and combined to derive the final prediction outcome. This paper selects InSAR monitoring data along a high-speed railway in inland China and uses the proposed method and ARMA and Prophet models to carry out comparative experiments. The experimental results show that compared with the ARMA and Prophet models, the method in this paper improves the root mean square error by 58.01% and 32.3%, and increases the mean absolute error by 62.69% and 33.78%, respectively. The predicted settlement values generated by our method exhibit better agreement with the actual InSAR monitoring values.

    Abstract Rechargeable batteries are of great significance for alleviating the growing energy crisis by providing efficient and sustainable energy storage solutions. However, the multiple issues associated with the diverse components in a battery system as well as the interphase problems greatly hinder their applications. Proteins and their subunits, peptides, and amino acids, are versatile biomolecules. Functional groups in different amino acids endow these biomolecules with unique properties including self-assembly, ion-conducting, antioxidation, great affinity to exterior species, etc. Besides, protein and its subunit materials can not only work in solid forms but also in liquid forms when dissolved in solutions, making them more versatile to realize materials engineering via diverse approaches. In this review, it is aimed to offer a comprehensive understanding of the properties of proteins and their subunits, and research progress of using these versatile biomolecules to address the engineering issues of various rechargeable batteries, including alkali-ion batteries, lithium-sulfur batteries, metal-air batteries, and flow batteries. The state-of-the-art advances in electrode, electrolyte, separator, binder, catalyst, interphase modification, as well as recycling of rechargeable batteries are involved, and the impacts of biomolecules on electrochemical properties are particularly emphasized. Finally, perspectives on this interesting field are also provided.

    Abstract In this study, the indoor constant temperature culture experiment was used to explore the mutual transformation of different forms of heavy metals. Appropriate types of passivating agents were screened, and the optimal addition amount was determined to realize the solidification and stabilization of heavy metals. The results showed that the dissolved copper (Cu), zinc (Zn), and lead (Pb) contents of the zeolite-treated soil decreased to the lowest. They were 219, 819, and 40 g/kg, respectively, which were 31.2, 6.5, and 38.5% lower than no passivating agent added (the control); the dissolved Cu, Zn, and Pb content gradually increased with the extension of time; 5% zeolite (Z4) treatment had the highest average content of Cu, Zn, and Pb in the residue state, respectively, 24, 48, and 19 mg/kg; and at the end of the test, the residual Zn content of Z4 treatment reached 50 mg/kg, which was 72.4% higher than that of the control. A comprehensive analysis of the changes in the dissolved state of the four heavy metals in the soil shows that Cu, Zn, cadmium (Cd), and Pb treated with zeolite have the best effect, followed by sepiolite, and finally palygorskite. Therefore, 5% zeolite can be used for the passivation restoration of heavy metals Cu, Zn, Cd, and Pb in the soil.

    Abstract The ecological environment of the hilly and gully area of the Loess Plateau in northern Shaanxi is fragile and the soil fertility is low. As a result, the yield and quality of Pear-jujube which constitute one of the dominant economic forests in this region, have been severely restricted. At present, the scientific application of fertilizer is important for comprehensively improving the quality of fruit trees, and for devising the optimal management of fruit trees. In particular, the application of organic fertilizers plays an important role in improving soil and improving fruit quality. In this experiment, a field study was conducted to understand the effects of different organic fertilizer applications on physiological growth, photosynthetic characteristics, reproductive growth and nutritional quality of Pear-jujube in the Loess Plateau. The results showed that organic fertilizer significantly promoted the physiological growth of Pear-jujube. The Pear-jujube bearing branch and leaf area under the soybean cake fertilizer (SC) treatment were 20.17 cm and 1246 mm

    Abstract This experiment is based on the 7-year-old dwarf and densely planted pear jujube in northern Shaanxi. The effects of applying organic fertilizer on water use, photosynthetic characteristics, and fruit quality of pear jujube are studied. The test has been carried out for two consecutive years. The results showed that fertilization treatments could promote soil moisture retention and utilization. Compared with the control (CK) in 2011, the average soil water content (SWC) of soybean cake fertilizer (SC) and sheep manure (SM) increased by 3.69 and 3.18 percentage points, respectively. The effect of SC on chlorophyll content was most significant. Fertilization can effectively improve the canopy structure of pear jujube. The transmittance of SC and SM decreased by 20.20% and 17.38%, respectively, in 2012. The gap scores were opposite to the leaf area index (LAI). Continuous application of organic fertilizer can significantly increase the net photosynthetic rate and stomatal conductance of pear jujube. The instantaneous water use efficiency of chemical fertilizer (CF), SC, SM, and biogas fertilizer (BM) increased by 0.44, 1.33, 0.96, and 0.61 percentage points, respectively. Organic fertilizer effectively increased the fruit setting rate, yield, and quality of fruits. After fertilization for two consecutive years, the quality of pear jujube fruit improved significantly. It indicated that long-term fertilization could effectively promote the growth and development, increase yield, and significantly improve the fruit quality of pear jujube in the loess hilly region of northern Shaanxi. The effect of soybean cake fertilizer was the most significant.

    Abstract In the planar flow casting (PFC) process, the cooling rate significantly affects the structure and properties of a cast ribbon. The influence of the thermal conductivity of the cooling wheel substrate on cooling rate was simulated by a numerical method, and it is shown that a higher thermal conductivity of the cooling wheel substrate leads to a higher cooling rate in the PFC process. Two copper-beryllium (Cu-2Be) rings with thermal conductivities of 175.3 W/m·K and 206.5 W/m·K were manufactured and installed onto a wheel core as the substrate of the cooling wheel. The effects of cooling rate on the soft magnetic properties of Fe-Si-B amorphous ribbons were investigated by pragmatic ribbon casting. The results show that the increment in the thermal conductivity of the cooling wheel substrate from 175.3 W/m·K to 206.5 W/m·K lowered the coercive force of amorphous ribbon from 2.48 A/m to 1.92 A/m and reduced the core losses at 1.4 T and 50 Hz by up to 22.1%.
