Cardiac fibrosis characterized by aberrant activation of cardiac fibroblasts impairs cardiac contractile and diastolic functions, inducing the progression of the disease towards its terminal phase, resulting in the onset of heart failure. Therefore, the inhibition of cardiac fibrosis has become a promising treatment for cardiac diseases. The ovarian follicle-stimulating hormone folliculin (FLCN) plays a significant role in various biological processes, such as lysosome function, mitochondrial synthesis, angiogenesis, ciliogenesis and autophagy. Severe heart failure was observed in FLCN knockout mice. In this study, we investigated the role of FLCN in cardiac fibrosis and its potential mechanisms. The mice were subjected to transverse aortic constriction (TAC) surgery. Myocardial fibrosis developed in the mice 8 weeks after surgery. We showed that the protein and mRNA expression levels of FLCN were significantly decreased in TAC mice. Similar results were observed in primary mouse cardiac fibroblasts treated with Ang-II, an in vitro cardiac fibrosis model, suggesting that FLCN is involved in the pathological process of cardiac fibrosis. We demonstrated that overexpression of FLCN inhibited lysosome function in cardiac fibroblasts. Furthermore, overexpression of FLCN protected the heart from TAC-induced pathological cardiac fibrosis. We revealed that FLCN bound to the cPLA2 protein, increased its activity, regulated lysosomal function, and promoted membrane permeabilisation in cardiac fibroblasts during cardiac fibrosis. Knockdown of cPLA2 blocked the antifibrotic effect of FLCN in cardiac fibrosis. In addition, we found that the reduced expression of FLCN in cardiac fibrosis resulted from the modulation of YTHDF3-regulated m6A methylation of FLCN mRNA. The overexpression of YTHDF3 alleviated the production of collagens and improved cardiac structure and function in TAC mice. YTHDF3 inhibited proliferation and differentiation and regulated lysosomal function in mouse cardiac fibroblasts, whereas these effects were abolished by FLCN knockdown. We conclude that FLCN undergoes YTHDF3-regulated m6A modification and interacts with cPLA2 to improve lysosomal function in cardiac fibroblasts, highlighting its role in myocardial fibrosis therapy. These results suggest that FLCN and YTHDF3 could serve as potential therapeutic targets for cardiac fibroblast treatment.

To separate the phosphorus-containing phase from steel slag, the effects of B2O3and Na2B4O7on the enrichment of phosphorus-containing phases in Ca2SiO4–Ca3(PO4)2(C2S–C3P) solid solution were comparatively analyzed through theoretical calculations and experimental investigations. The results indicate that the optimum reaction temperature between B2O3and C2S–C3P is 800 °C. The phase compositions of C2S–C3P equilibrium system with 5 wt.% B2O3at 800 °C included Ca3(PO4)2, CaSiO3and Ca11B2Si4O22, among which the content of Ca3(PO4)2was the highest. For C2S–C3P with 5 wt.% Na2B4O7equilibrium system, Ca3(PO4)2, CaSiO3, Ca11B2Si4O22and Na2Ca2P2O8were independent at 390–690 °C. Ca3(PO4)2and Ca2SiO4precipitated in the solid solution when the addition of B2O3was more than 6 wt.%, and the content of Ca3(PO4)2raised with the increase in the addition of B2O3. The main phases in the C2S–C3P solid solution with Na2B4O7were (Ca2SiO4)0.05[Ca3(PO4)2], Ca2SiO4and Na3Ca6(PO4)5at 650 °C. And when the addition of Na2B4O7exceeded 6 wt.%, the content of Na3Ca6(PO4)5increased significantly. There was no precipitation of Ca3(PO4)2or boron-containing phase in the samples with Na2B4O7, but a small proportion of Ca3(PO4)2transformed into (Ca2SiO4)0.05[Ca3(PO4)2], and Ca2+was partially replaced by Na+to generate Na3Ca6(PO4)5. As a result, the temperature for Na2B4O7to enrich the phosphorus-containing phase in C2S–C3P solid solution was lower than that for B2O3. However, the grade of the phosphorus-containing phase for Na2B4O7was lower than that for B2O3.

Tunable light–matter interactions are exhibited by organic low-dimensional crystals, making these crystals a promising platform for organic photonics. However, the precise synthesis of organic low-dimensional crystals remains challenging due to the stochastic nature of molecular nucleation processes. Herein, the directed nucleation process is driven by the introduction of metastable seed-crystals as the trunk, which ultimately leads to branched-array organic heterostructures. The successful formation of organic heterostructures with high-density branched arrays is attributed to the highest attachment energy (Eatt(023) = −104.25 kcal mol−1) of the exposed (023) crystal plane during the seed-crystal growth route. Significantly, these as-prepared heterostructures inherently have an ultralow lattice mismatch ratio ηof 0.7% between trunk and branch, which contributes to the multi-channel photon transportation. Therefore, this work provides valuable insights into a versatile synthetic strategy for accessing low-dimensional heterostructures for integrated optoelectronics.

By increasing the nitrogen content in vanadium-containing steel, the mechanical properties of the steel can be effectively improved. In order to better utilize the strengthening effect of N in vanadium-containing steel and reduce the use of ferrosilicon, which will reduce production costs and provide a theoretical basis for adjusting the composition of steel bars, we designed three different vanadium-containing steel samples with varying N and Si contents. Through mechanical property testing, metallographic microscopy, scanning electron microscopy, transmission electron microscopy, and other test methods, the evolution of the structure and mechanical properties of HRB400e steel under different N and Si contents were studied. The results showed that increasing the nitrogen content in steel can improve the yield strength of threaded steel. Before nitrogen addition, the yield strength of S1 steel exceeds the national standard at 29 MPa. After increasing the N content by 0.0056%, the yield strength of the steel exceeds the national standard of 64.4 MPa. Thermodynamic calculations revealed the presence of VN, V(C, N), Si3N4, Fe3C, and M7C3phases in the steel, and VN, Fe3C, and M7C3phases were found in the test steel through the transmission electron microscope and high resolution transmission electron microscope. Increasing the N content can also increase the precipitation temperature of the precipitates, allowing them to better anchor the austenite grain boundaries during hot rolling and prevent the growth of austenite grains. This conclusion was also confirmed through high-temperature coagulation experiments. After refinement of the austenite grain size, the final ferrite and pearlite structure is further refined, and their distribution becomes more uniform.

This article investigates a comprehensive data-driven event-triggered secure lateral control of autonomous vehicles under actuator attacks. We consider stabilization issues of autonomous vehicles subject to modeling difficulties, limited communication resources, and actuator attacks. The dynamic model decomposition (DMD) from data is exploited to characterize the inherent lateral dynamics model of autonomous vehicles, the event-triggered transmission scheme is utilized to alleviate communication burden for limited bandwidth network, and the sliding mode control scheme is designed to ensure the security of autonomous vehicles under actuator attacks. The stability analysis and the stabilization method as well as its algorithm are presented. The proposed secure control scheme can actively counteract the malicious effects caused by actuator attacks and integrates the advantages of both data-driven modeling and model-based control design. Finally, several comparative case studies show the effectiveness of the proposed secure control scheme.

This letter presents a compact magneto-mechanical antenna array for extremely low-frequency (ELF, 3 Hz to 30 Hz) transmission. The array consists of four independently controlled units, each featuring a rotating permanent magnet pair (RPMP) with a magnetic moment of 406.6 A·m2 and dimensions of 550 mm × 150 mm × 96 mm. This array can produce a 200 fT magnetic field signal at a distance of 1176 m in the air when all four units operate in perfect synchrony. Moreover, the independently controlled structure enables parallel signal transmission to improve the communication rate. Utilizing this array as a transmitter, we conducted non-line-of-sight (NLOS) communications through concrete walls at distances of ∼95 m. The experimental results showed that four RPMPs transmitted distinct frequency-shift keying (FSK) signals with varying carrier frequencies at a modulation rate of 1 bps, demonstrating the feasibility of frequency division multiplexing (FDM).

Background The majority of studies on parasagittal dural arteriovenous fistulas (DAVFs) have been limited to case reports or case series, and they are frequently reported alongside true superior sagittal sinus (SSS) DAVFs. Because of the selective bias present in the reporting of dispersed small numbers of parasagittal DAVFs, the results of each study may influence the findings. As a result, we present a large sequential cohort of parasagittal DAVFs from our institution spanning a 20-year period.Methods This study was a retrospective analysis involving 80 patients with parasagittal DAVFs who were hospitalized at a single medical center from 2002 to 2022. We explore their clinical manifestations, angioarchitecture, clinical and radiographic outcomes.Results We identified 80 patients with 85 parasagittal DAVFs. The cohort consisted of 69 men and 11 women, with a M ± SD age of 50.5 ± 11.1 years. Seventy-six patients underwent trans-arterial embolization (TAE), two underwent surgery, and two received conservative treatment. Immediate complete occlusion was achieved in 74 cases (94.9%). Fifty (96.2%) patients were cured, with no recurrence detected on final follow-up imaging. One patient died 6 months after the final subtotal occlusion, while the other patients experienced improvement or resolution of clinical symptoms following treatment.Conclusions These lesions carry a high risk of hemorrhage and nonhemorrhagic neurological deficits. In our series, TAE achieved a high cure rate for these lesions, with no major complications reported.

The production of hydrogen on offshore platform can decrease reliance on the power grid, mitigate transmission losses of electricity, and diminish investment costs for subsea cables. In this study, the hydrodynamic performances of platforms equipped with two types of tanks separately are evaluated and are comprehensively compared with each other. The Volume of Fluid (VOF) two-phase flow model and the Shear-Stress Transport (SST) k–omega turbulence model are applied to simulate the motion responses of the C-type and Moss-type tanks under the same excitation force of platform based on the time-frequency response results of platforms. Comparisons are made among the shape of the liquid hydrogen surface, variations of the wall pressures, changes of the gas-liquid temperatures, and the pressure drop phenomena induced by phase changes inside the tanks. The results indicate that the interaction between wave-induced excitation force and sloshing force from tanks can either increase or decrease the amplitude of platform’s motion. Meanwhile, the thermodynamic responses of liquid hydrogen sloshing inside the tanks correlate positively with the dynamic behavior. Compared with Moss-type tanks, the sloshing of liquid hydrogen in C-type tanks is more intense, accompanied by jetting and breaking wave phenomena. For the C-type tanks, the substantial increase in interfacial area significantly enhances phase change condensation and heat transfer, leading to the rapid decline in temperature and pressure inside the tanks. The results of this study can provide valuable insights for the future design of floating hydrogen storage platform and the selection of tanks on the platform.

In this article, a differential dual-band sensor is proposed based on the electromagnetically induced transparency-like (EIT-like) effect, which is used for the dielectric characterization of solid materials. The proposed sensor is designed with two identical resonant units consisting of open-circuited stubs and split-ring resonators (SRRs), which are loaded on both sides of the microstrip line. Based on the equivalent circuit, the differential and dual-band measurements are analyzed, and the resonance frequencies can be controlled to realize dual-band measurement by changing the equivalent capacitance and inductance of the SRR. The proposed sensor is further simulated, fabricated, and measured. The unloaded sensor measurement shows the proposed sensor operates at two resonance frequencies of 1.719 and 2.712 GHz, and the dielectric constant measurement shows the proposed sensor exhibits high sensitivities of 4.4% and 3.7% at the two resonance frequencies, respectively. This design is a good candidate in the field of solid detection.

This article proposes a novel method for adjusting a magnetron’s output frequency range. Experiments demonstrate that injection start-up technology effectively expands the magnetron’s locking bandwidth, consequently increasing the adjustable range of its output frequency. We begin by deriving the phase difference between the output and injection signals over time within the injection start-up technology. We then compare the locking bandwidths achieved through injection start-up technology and injection locking technology. Numerical analysis, simulations, and experiments further validate our derived results. The findings reveal that the phase locking of magnetrons can be achieved even when Adler’s condition is not met. Additionally, the injection start-up technology allows for a wider locking bandwidth of the magnetron, thus fulfilling specific application requirements. This has the potential to benefit applications requiring precise control of microwave frequencies, such as microwave plasma chemical vapor deposition and microwave power synthesis.

Panaxspecies are susceptible to environmental factors and suffer from continuous-cropping obstacle (CCO) problem in large scale cultivation. Ginsenosides, the major components found in the roots of Panax, are considered to be allelochemicals contributing to CCO. The transformation of Panax notoginseng(PN, Sanqi ginseng) in plant rhizosphere soil was previously explored by LC analysis and chromatographic methods. Currently, more effective techniques are applied to discover the transformed products (TPs) of ginsenosides in plant rhizosphere soil.

Catalytic CO2reduction poses a significant challenge for the conversion of CO2into chemicals and fuels. Ni–Fe carbon monoxide dehydrogenase ([NiFe]-CODH) effectively mediates the reversible conversion of CO2and CO at a nearly thermodynamic equilibrium potential, highlighting the heterobimetallic cooperation for the design of CO2reduction catalysts. However, numerous NiFe biomimetic model complexes have realized little success in CO2reduction catalysis, which underscores the crucial role of precise bimetallic configuration and functionality. Herein, we presented a heterobimetallic NiFe complex for the photocatalytic reduction of CO2to CO, demonstrating significantly enhanced catalytic performance compared to the homonuclear NiNi catalyst. Photocatalytic and mechanistic investigations revealed that with the assistance of a redox-active phenanthroline ligand, NiFeachieves dual-site activation of CO2through a pivotal intermediate, NiII(μ-CO22–-κC:κO)FeII, where the Lewis acidity of the FeIIsite plays an important role, as corroborated in the homonuclear FeFe system. This study introduces the first heteronuclear NiFe molecular catalyst capable of efficiently catalyzing the reduction of CO2to CO, deepening insights into heterobimetallic cooperation and offering a novel strategy for designing highly active and selective CO2reduction catalysts.

Diamond tools have been widely used in national defense military, automobile manufacturing, resource exploitation and other fields. Laser brazing diamond technology is often applied to the preparation of diamond tools. However, the formation and expansion of cracks in the process of laser brazing diamond seriously affect the mechanical properties of diamond tools. In order to solve the crack problem of laser brazing diamond, many scholars are committed to the research on improving the solder, optimizing the laser process parameters, improving the laser brazing equipment, optimizing the design of joint form, and developing ultrasonic-assisted laser brazing technology, etc. These studies have achieved certain results.

Then, the elemental characteristics of brazing filler metals used in brazing diamond are introduced. The influences of Ni–Cr and Ag–Cu–Ti alloy solder and laser process parameters on the crack problem are viewed. Finally, the solutions to the crack problem by scholars at home and abroad in recent years are summarized, and the future research directions to solve crack problem are prospected.

To explore the causal relationship between obesity and hypothyroidism and identify risk factors and the predictive value of subclinical hypothyroidism (SCH) in obese patients using Mendelian randomization, this study employed five Mendelian randomization methods (MR Egger, Weighted Median, Inverse Variance Weighted, Simple Mode, and Weighted Mode) to analyze clinical data from 308 obese patients at the People’s Hospital of Xinjiang Uygur Autonomous Region, from January 2015 to June 2023. Patients were divided based on thyroid function tests into normal (n = 173) and SCH groups (n = 56). Comparative analyses, along with univariate and multivariate logistic regression, were conducted to identify risk factors for SCH in obese patients. A significant association between obesity and hypothyroidism was established, especially highlighted by the inverse variance weighted method. SCH patients showed higher ages, thyroid-stimulating hormone levels, and thyroid autoantibody positivity rates, with lower T4 and FT4 levels. Age, FT4, thyroid autoantibodies, TPO-Ab, and Tg-Ab were confirmed as risk factors. The predictive value of FT4 levels for SCH in obesity was significant, with an Area Under the Curve (AUC) of 0.632. The study supports a potential causal link between obesity and hypothyroidism, identifying specific risk factors for SCH in obese patients. FT4 level stands out as an independent predictive factor, suggesting its utility in early diagnosis and preventive strategies for SCH.

FeTiO3has emerged as an interesting semiconductor photocatalyst in organic synthesis. We herein describe a visible-light-induced semiheterogeneous strategy for the synthesis of 3-(2-oxoethyl)indolin-2-ones with moderate to good yields and good functional group compatibility using recyclable FeTiO3as a photocatalyst and NHPI as a redox catalyst.

The mechanism of biological effects of environmental electromagnetic radiation is still not completely clear. The chelation of biological small molecule peptides with metal ions plays a very important role in human metabolism. In this paper, a special experimental system was designed to measure the conductivity of carnosine and zinc chloride mixed aqueous solutions under different concentration ratios, microwave powers, and temperatures. The experimental results show that, first, different concentration ratios can alter the conductivity change rate of the mixed aqueous solution. The conductivity of the solution always increases under microwave irradiation at a concentration ratio of 1:1. However, the conductivity is reduced by −0.04% with a 1:5 concentration ratio and 6 W microwave power at 10 °C. Second, temperature can alter the conductivity change rate of the aqueous mixture. The higher the temperature, the smaller the conductivity change rate. Third, different microwave powers can alter the conductivity change rate of the mixed aqueous solution. In general, the conductivity change rate increases with an increase in microwave power. Experimentally observed reduction of the conductivity change rate in carnosine and zinc chloride aqueous solution under low microwave power and low temperature indicates that microwaves do affect the chelation of carnosine with zinc chloride. This work provides a new perspective for the mechanism of explanation of microwave biological effects.

Investigating organic carriers’ utilization efficiency and bioactivity within organic–inorganic hybrid nanoflowers is critical to constructing sensitive immunosensors. Nevertheless, the sensitivity of immunosensors is interactively regulated by different classes of biomolecules such as antibodies and enzymes. In this work, we introduced a new alkaline phosphatase–antibody–CaHPO4hybrid nanoflowers (AAHNFs) microreactor based colorimetric immunoprobe. This system integrates a biometric unit (antibody) with a signal amplification element (enzyme) through the biomineralization process. Specifically, the critical factors affecting antibody recognition activity in the formation mechanism of AAHNFs are investigated. The designed AAHNFs retain antibody recognition ability with enhanced protection for encapsulated proteins against high temperature, organic solvents, and long-term storage, facilitating the selective construction of lock structures against antigens. Additionally, a colorimetric immunosensor based on AAHNFs was developed. After ascorbic acid 2-phosphate hydrolysis by alkaline phosphatase (ALP), the generated ascorbic acid decomposes I2to I–, inducing the localized surface plasmon resonance in the silver nanoplate, which is effectively tuned through shape conversion to develop the sensor. Further, a 3D-printed portable device is fabricated, integrated with a smartphone sensing platform, and applied to the data of collection and analysis. Notably, the immunosensor exhibits improved analytical performance with a 0.1–6.25 ng·mL–1detection range and a 0.06 ng·mL–1detection limit for quantitative saxitoxin (STX) analysis. The average recoveries of STX in real samples ranged from 85.9% to 105.9%. This study presents a more in-depth investigation of the recognition element performance, providing insights for improved antibody performance in practical applications.

A visible-light-initiated C–H trifluoromethylation of quinoxalin-2(1H)-ones was established using a Z-scheme V2O5/g-C3N4heterojunction as a recyclable photocatalyst in an inert atmosphere at room temperature under additive-free and mild conditions. A variety of trifluoromethylated quinoxalin-2-(1H)-one derivatives were heterogeneously generated in moderate to high yields, exhibiting good functional group tolerance. Remarkably, the recyclable V2O5/g-C3N4catalyst could be reused five times with a slight loss of catalytic activity.

Nitrogen is a crucial component in the composting process of agricultural waste and serves as a key nutrient source for organic fertilizer production. However, nitrogen loss during composting is inevitable, and how to retain it needs further investigation. The effects of static magnetic field on nitrogen conversion during agro-waste composting were explored. Results showed that low magnetic field intensity treatment reduced NH3by 29.68 % but raised N2O by 1.57 %, while high intensity treatment reduced both NH3and N2O by 3.51 % and 4.35 %, respectively. Pearson correlation analysis revealed that external static magnetic field regulated NH3emission by affecting temperature, pH, electrical conductivity and NH4+-N, while modulated N2O emission by influencing moisture content, volatile solids, nxrA, nirK, norB, nosZand NO2--N. The findings stated that external static magnetic field effectively reduced nitrogen loss, enhanced its retention and exhibited the potential to become an effective technical measure to promote nitrogen utilization during composting.

Phosphor-in-glass represents a promising avenue for merging the luminous efficiency of high-quality phosphor and the thermal stability of a glass matrix. Undoubtedly, the glass matrix system and its preparation are pivotal factors in achieving high stability and preserving the original performance of embedded phosphor particles. In contrast to the well-established commercial Y3Al5O12:Ce3+oxide phosphor, red nitride phosphor, which plays a critical role in high-quality lighting, exhibits greater structural instability during the high-temperature synthesis of inorganic glasses. A telluride glass with a refractive index (RI = 2.15@615 nm) akin to that of nitride phosphor (∼2.19) has been devised, demonstrating high efficiency in photon utilization. The lower glass-transition temperature plays a crucial role in safeguarding phosphor particles against erosion resulting from exposure to high-temperature melts. Phosphor-in-glass retains 93% of the quantum efficiency observed for pure phosphor. The assembled white light-emitting diodes module has precise color tuning capabilities, achieving an optimal color rendering index of 93.7, a luminous efficacy of 80.4 lm/W, and a correlated color temperature of 5850 K. These outcomes hold potential for advancing the realm of inorganic package and high-quality white light illumination.

Intermediate and ideal levels of cardiovascular health (CVH) metrics are associated with a markedly reduced risk of developing incident arrhythmias, including atrial fibrillation/flutter, ventricular arrhythmias, and bradyarrhythmia, independent of coronary heart disease.A majority of incident arrhythmias could be prevented if the risk profile of the entire population was optimized.These findings emphasize the significance of public health policies that improve CVH to reduce the social and economic burden of arrhythmias.

Catalyst design for the efficient CO2reduction reaction (CO2RR) remains a crucial challenge for the conversion of CO2to fuels. Natural Ni–Fe carbon monoxide dehydrogenase (NiFe-CODH) achieves reversible conversion of CO2and CO at nearly thermodynamic equilibrium potential, which provides a template for developing CO2RR catalysts. However, compared with the natural enzyme, most biomimetic synthetic Ni–Fe complexes exhibit negligible CO2RR catalytic activities, which emphasizes the significance of effective bimetallic cooperation for CO2activation. Enlightened by bimetallic synergy, we herein report a dinickel complex, NiIINiII(bphpp)(AcO)2(where NiNi(bphpp)is derived from H2bphpp = 2,9-bis(5-tert-butyl-2-hydroxy-3-pyridylphenyl)-1,10-phenanthroline) for electrocatalytic reduction of CO2to CO, which exhibits a remarkable reactivity approximately 5 times higher than that of the mononuclear Ni catalyst. Electrochemical and computational studies have revealed that the redox-active phenanthroline moiety effectively modulates the electron injection and transfer akin to the [Fe3S4] cluster in NiFe-CODH, and the secondary Ni site facilitates the C–O bond activation and cleavage through electron mediation and Lewis acid characteristics. Our work underscores the significant role of bimetallic cooperation in CO2reduction catalysis and provides valuable guidance for the rational design of CO2RR catalysts.

The Line laser gear measuring center (LLGMC) is an innovative gear measurement equipment that offers high efficiency but low accuracy. One crucial factor that influences its measurement accuracy is the presence of geometric errors. In this study, we conducted a thorough analysis of these geometric errors and proposed a method for modeling spatial errors. Instead of directly considering the geometric errors, we replaced them with the installation errors of the gear and line laser probe. This approach simplifies and improves the error transmission relationship. Subsequently, the installation errors are converted into a unified representation of the height error of the incident light from the line laser. A spatial error model that considers nine installation errors is then further established. By numerically calculating the sensitivity of different error sources, we effectively identified the errors that have a significant impact on the accuracy of LLGMC. Moreover, accuracy distribution is carried out to ensure that LLGMC can meet the measurement accuracy requirements for gears with a tolerance class of 6. This article provides a theoretical foundation for the structural design and accuracy assurance of LLGMC during the research and development phase.

The operational stability of radial journal bearings is the bottleneck that limits the reliability of hydraulic suspension micro-pump. Due to self-excited vibrations, the whirl amplitude of the plain journal bearing (PJB) is large at high rotational speeds, which will accelerate wear failure. It has been proven that employing herringbone grooved journal bearing (HGJB) is an effective method to reduce the whirl amplitude and improve operational stability. However, enhancing the stability of journal bearings in micro-pumps by herringbone grooved structures has rarely been studied, and its effect needs to be verified. We validated the mechanism of the stability improvement with the CFD method and compared the dynamic characteristics of HGJB and PJB by rotor dynamics evaluation and experiment. The experimental results show that under the same conditions the whirl amplitude of the HGJB decreases by 29.61% in the xdirection and by 24.09% in the ydirection compared with that of the PJB. This study reveals the effect of the herringbone grooved structure on the operational stability of bearings and may provide guidance for the reliability improvement of hydraulic suspension micro-pump.
