Logistic equation was used to fit the plant height growth of wheat and alfalfa in different intercropping treatments, and the effects of intercropping on the plant height growth of wheat and alfalfa were analyzed according to the results of fitting curve model parameters. The results showed that the plant height growth of wheat and alfalfa under different intercropping patterns was in line with "S" curve. According to the turning point of the growth curve, the plant height growth can be divided into three stages: gradual growth stage, linear growth stage and slow growth stage. In late March, wheat and alfalfa began to enter linear growth phase, which lasted about one month and one and a half months, respectively. The linear growth of wheat and alfalfa in all treatments accounted for more than 50% of the total growth in growth period. Intercropping alfalfa extended the linear growth period of wheat, but reduced the growth rate and amount of wheat in the linear growth period. While intercropping with wheat shortened the linear growth period of alfalfa, but accelerated its growth rate.

BACKGROUND Submucosal tumors (SMTs) refer to elevated lesions that originate from the layers below the mucosa of the digestive tract, including the muscularis, submucosa and muscularis propria. With the development and application of endoscopy and endoscopic ultrasonography (EUS), the detection rate of SMTs has increased significantly in recent years. Various diseases can lead to SMTs. However, a foreign body embedded in the gastric antrum showing clinical manifestations of a SMT is rare. CASE SUMMARY We report the case of a 47-year-old woman, who presented with upper abdominal discomfort for one year, and was subsequently diagnosed with a gastric submucosal lesion caused by an embedded foreign body by EUS and computed tomography. Considering the size and potential complications of this lesion, endoscopic full-thickness resection was performed to achieve full resection in our endoscopy center. A fish bone was found in the lesion during the operation, and was successfully removed, and the defect was later closed with endoscopic purse-string sutures. CONCLUSION This case report highlights the management strategies of SMTs, the importance of being familiar with diagnostic methods related to submucosal lesions, and being able to conduct effective treatment when this rare condition is highly suspected.

The polypyrrole (PPy) coating and polypyrrole-molybdate (PPy-MoO 4 2− ) coating were electro-polymerized in sodium salicylate solution by cyclic voltammetry (CV) on the AZ31 Mg alloy surface. Surface morphology of PPy coating and PPy-MoO 4 2− coating on Mg alloy surface before and after being corrupted was observed by scanning electron microscopy (SEM). Attenuated total reflection-infrared (ATR-IR) spectra showed the characteristic ring stretching peaks of the PPy coating and PPy-MoO 4 2− coating, and also revealed the influence of MoO 4 2− on the characteristic ring stretching peaks on PPy. The surface resistance was measured by four-point probe method. The open circuit potential (OCP), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization analyzed the corrosion resistance performance of PPy coating and PPy-MoO 4 2− coating on the Mg alloy surface in 3.5% NaCl solution immersing for 12 h. The results show that the surface morphology of PPy-MoO 4 2− coating is compact. And the corrosion current density of PPy-MoO 4 2− coating is lower three orders than that of the PPy coating. The PPy-MoO 4 2− coating on the Mg alloy surface has better corrosion resistance and smaller surface resistance than the PPy coating because of the existence of the molybdate ion.

With the wide application of radio frequency identification (RFID) technology, its security privacy issues are becoming more and more prominent. A RFID mutual-authentication protocol with synchronous updated-keys based on Hash function is proposed to tackle those problems in this paper. An updated mechanism of the dynamic tag keys is introduced and a self-synchronized scheme is designed in the protocol, which has achieved the second verification for the tags. The security of the protocol is verified and analyzed by the Burrows-Abadi-Needham (BAN) logic and the attack models, moreover it has been compared with the existing schemes of security properties and its storage and computational performance. The results show that the proposed protocol has the ability to considerably reduce the amount of computation between tags and back-end database, and enhance the search efficiency of the whole system without the additional cost of the tags. It can satisfy safe requirements of RFID system effectively, also improve the authentication efficiency. The proposed protocol is more suitable for the low cost RFID system.

To analyze obstetric complications associated with aplastic anemia (AA) among pregnant women and analyze the underlying factors.A retrospective analysis of 60 pregnancies with AA. Thirty four of these patients were grouped as complicated group having obstetric complications and the rest 26 without complications as the control group. Comparative analysis was conducted to access the related risk factors, which may affect the maternal and fetal complications.The major maternal complications in this study were premature labor, gestational diabetes, pre-eclampsia, acute heart failure, postpartum hemorrhage, and severe postpartum infection. Premature birth, fetal growth restriction and stillbirths accounted for 27.3%, 5.0% and 6.7% of prenatal mortality. Twenty six of patients had uncomplicated pregnancies. Patients without complications had higher mean hemoglobin concentration (75.38 ± 16.19 g/L) and platelet counts (23.92 ± 14.82 × 10(9) cells/L) than did women with complications (mean hemoglobin concentration, 61.47 ± 15.15 g/L, p = 0.001; mean platelet counts, 12.11 ± 7.87 × 10(9) cells/L, p0.001).Pregnancies associated with AA can carry the risk of multiple maternal and fetal complications. Low hemoglobin concentration and platelet counts may be the primary risk factors for obstetric complications in pregnancies associated with AA.

Silicon (Si)-based materials with a super-hydrophobic surface were prepared using microscale rough surfaces, which were subsequently modified by organic compounds with low surface energies. However, the super-hydrophobicity was gradually lost because of the degradation of the organic compounds when applied to an outer environment. Herein, a Si-based film with a super-hydrophobic surface fabricated by chemical vapor deposition (CVD) using a liquid metal (tin) as the growth substrate is reported. We found that the film was composed of vertical Si/SiO2 hierarchical wires upon characterization by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). Reasons for the generation of this super-hydrophobicity are given using the Cassie model. We conclude that the special Si/SiO2 hierarchical structure plays an important role in the super-hydrophobic performance of the film. Compared with the previous Si-based material with a super-hydrophobic surface, this novel structure promises to widen its area of application since its super-hydrophobicity is independent of chemical modification.

The mesoscopic nonlinear inductance-capacitance circuit is a typical anharmonic oscillator, due to diodes included in the circuit. In this paper, using the advanced quantum theory of mesoscopic circuits, which based on the fundamental fact that the electric charge takes discrete value, the diode included mesoscopic circuit is firstly studied. Schr?dinger equation of the system is a four-order difference equation in representation. Using the extended perturbative method, the detail energy spectrum and wave functions are obtained and verified, as an application of the results, the current quantum fluctuation in the ground state is calculated. Diode is a basis component in a circuit, its quantization would popularize the quantum theory of mesoscopic circuits. The methods to solve the high order difference equation are helpful to the application of mesoscopic quantum theory.

This paper presents a novel approach to hyperchaos control of hyperchaotic systems based on impulsive control and the Takagi–Sugeno (T–S) fuzzy model. In this study, the hyperchaotic Lu system is exactly represented by the T–S fuzzy model and an impulsive control framework is proposed for stabilizing the hyperchaotic Lu system, which is also suitable for classes of T–S fuzzy hyperchaotic systems, such as the hyperchaotic Rossler, Chen, Chua systems and so on. Sufficient conditions for achieving stability in impulsive T–S fuzzy hyperchaotic systems are derived by using Lyapunov stability theory in the form of the linear matrix inequality, and are less conservative in comparison with existing results. Numerical simulations are given to demonstrate the effectiveness of the proposed method.

In this work, the stability issues of the equilibrium points of the cellular neural networks with multiple time delays and impulsive effects are investigated. Based on the stability theory of Lyapunov–Krasovskii, the method of linear matrix inequality (LMI) and parametrized first-order model transformation, several novel conditions guaranteeing the delay-dependent and the delay-independent exponential stabilities are obtained. A numerical example is given to illustrate the effectiveness of our results.

The open electron resonator is a mesoscopic device that has attracted considerable attention due to its remarkable behavior: conductance oscillations. In this paper, using an improved quantum theory to mesoscopic circuits developed recently by Li and Chen, the mesoscopic electron resonator is quantized based on the fundamental fact that the electric charge takes discrete value. With presentation transformation and unitary transformation, the Schrodinger equation becomes an standard Mathieu equation. Then, the detailed energy spectrum and wave functions in the system are obtained, which will be helpful to the observation of other characters of electron resonator. The average of currents and square of the current are calculated, the results show the existence of the current fluctuation, which causes the noise in the circuits, the influence of inductance to the noise is discussed. With the results achieved, the stability characters of mesoscopic electron resonator are studied firstly, these works would be benefit to the design and control of integrate circuit.

The permanent magnet synchronous motors (PMSMs) may have chaotic behaviours for the uncertain values of parameters or under certain working conditions, which threatens the secure and stable operation of motor-driven. It is important to study methods of controlling or suppressing chaos in PMSMs. In this paper, robust stabilities of PMSM with parameter uncertainties are investigated. After the uncertain matrices which represent the variable system parameters are formulated through matrix analysis, a novel asymptotical stability criterion is established. Some illustrated examples are also given to show the effectiveness of the obtained results.

The three pollution indexes ( SO 2 , NO 2 and PM 10 ) and the daily air pollution indexes (APIs) of Shanghai in China are analyzed by rescaled range analysis ( R / S ) , detrended fluctuation analysis (DFA) and spectral analysis. The results show that the temporal scaling behaviors in all the four series exhibit two different power laws. In shorter temporal scaling, all the series indicate the similar persistence corresponding to the annual cycle. However, in longer temporal scaling, the trends are different for the four series, which reflect the different inherent dynamic nature of various pollutant series. The fluctuations of Hurst exponent ( H ) , DFA exponent ( α ) and power spectral density index ( β ) with increasing threshold magnitude are analyzed. Our results suggest that there are different self-organized critical states in these air pollutants.

The permanent magnet synchronous motors (PMSMs) may experience chaotic behaviours with systemic parameters falling into a certain area or under certain working conditions, which threaten the secure and stable operation of motor-driven. Hence, it is important to study the methods of controlling or suppressing chaos in PMSMs. In this work, the Takagi–Sugeno (T-S) fuzzy impulsive control model for PMSMs is established via the T-S modelling methodology and impulsive technology. Based on the new model, the control conditions of asymptotical stability and exponential stability for PMSMs have been derived by the Lyapunov method. Finally, an illustrated example is also given to show the effectiveness of the obtained results.
