The Riemann Problem for a system of hyperbolic conservation laws of form $\begin{equation*}\begin{split}u_t + f(u, v)_x &= 0,\\ v_t + g(u,v)_x &= 0 \\ \end{split} \tag{1}\end{equation*} with arbitrary initial constant states \begin{equation*}\tag{2} (u_0(x), v_0(x)) = \begin{cases} (u_1, v_1), & x < 0,\\(u_r, v_r), & x > 0, \end{cases}\end{equation*}$ is considered. We assume that $f_v < 0, g_u < 0$. Let li (ri) be the left (right) eigenvectors of $dF \equiv d(f, g)$ for eigenvalues $\lambda_1 < \lambda_2$. Instead of assuming the usual convexity condition dλi(ri) ≠ 0, i = 1, 2, we assume that dλi(ri) = 0 on disjoint union of 1-dim manifolds in the (u, v) plane. Oleinik's condition (E) for single equation is extended to system (1); again call this new condition (E). Our condition (E) implies Lax's shock inequalities and, in case dλi(ri) ≠ 0, the two are equivalent. We then prove that there exists a unique solution to the Riemann Problem (1) and (2) in the class of shocks, rarefaction waves and contact discontinuities which satisfies condition (E).

Generalized symmetry of designs and estimators is defined to be invariance under a subgroup of the group of label permutations. A simple sufficient condition in terms of the design is given for the generalized order statistic, of which each generalized symmetric estimator is a function, to be complete. This condition is shown also to be necessary when the range of possible values for each characteristic is sufficiently large.

There are several types of dissipation—the viscosity and heat conductivity, the nonlinearity and the coupling of distinct characteristics—that can occur in the system of conservation laws. In addition to these corresponding types of dissipation, there are other consequences of the H-theorem and the boundary dissipative effects for the kinetic theory. We discuss these issues and raise questions.

In [2] the author proposed the entropy condition $(E)$ and solved the Riemann problem for general $2 \times 2$ conservation laws $u_t + f(u, v)_x = 0, v_t + g(u, v)_x = 0$, under the assumptions that the system is hyperbolic, and $f_u \geqslant 0$ and $g_v \leqslant 0$. The purpose of this paper is to extend the above results to a much wider class of $2 \times 2$ conservation laws. Instead of assuming that $f_u \geqslant 0$ and $g_v \leqslant 0$, we assume that the characteristic speed is not equal to the shock speed of different family. This assumption is motivated by the works of Lax [1] and Smoller [4].

In this study, the author examines the results of questionnaire given to 92 teachers in community-based Chinese schools (CCSs) in Southern California. Information was sought from the teachers on their academic background and aspirations, the reasons for them to choose to teach in the CCSs, and their views on the quality of the education provided by CCSs. The teachers were also asked how they saw the CCSs developing in the future. The paper discusses the findings in detail and their implications for the future of CCSs.

This study examines whether a change in motivation occurred from 5th-grade elementary school to 6th-grade middle level school for students in the People's Republic of China, as had been identified among U.S. students. A total of 260 Chinese students, 138 in the 5th grade and 122 in the 6th grade, participated in the study. The students' motivation was examined using the Patterns of Adaptive Learning Survey in the following aspects: personal achievement goal orientations, perceptions of the classroom goal structure, academic efficacy, academic self-handicapping strategies, and cultural dissonance between home and school. While no significant difference was reported between male and female students, significant main effects were found between students in the 5th and 6th grades. Specifically, a significant difference was found in two out of eight subcategories: performance approach goal orientation and cultural dissonance between home and school. The findings indicate that the causes of difference in the Chinese students' motivation by grade/school level could be different from those of their U.S. counterparts.

Clinical psychopharmacological research has focused on several aspects in the last decade in China. First, attention was paid to new drug trials, mainly on newly developed or imported antidepressants or antipsychotics. More and more newly developed antidepressants like SSRI, fluoxetine, paroxetine, sertraline, and citalopram are now available or under clinical observation. Second, studies on the relationship between blood level and clinical response of antidepressants, amitriptyline, or antipsychotics, haloperidol and clozapine were undertaken. Results on amitriptyline showed that the clinical antidepressive effect of the drug was correlated linearly to the parent compound, amitriptyline, and curvilinearly to the hydroxylated metabolite, 10‐hydroxynortryptyline. It was found that the plasma level of haloperidol correlated curvilinearly to the clinical antipsychotic effect on schizophrenics with a therapeutic window ranging between 4.2 and 20 ng/mL. Third, pharmacokinetic studies on antidepressants, amitriptyline, imipramine, and maprotiline were undertaken. The results showed longer clearance rate and/or t1/2 in Chinese literature than those reported in Western literature.

A fine-quality, regular Cu-Mg-Al hydrotalcite-like compound was synthesized via the glycothermal method using CuCl2 \cdot 2H2O, MgCl2 \cdot 6H2O, AlCl3 \cdot 6H2O, and Na2CO3 as raw materials and sodium hydroxide as the precipitant. Hydrotalcite samples were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric-differential thermal analysis, and Brunauer-Emmett-Teller N2 surface area measurements. The influence of glycol content on the characteristics of the sample was investigated. The results show that the glycol content in the system had a greater impact on regular hydrotalcite with an intercalated structure. A Cu-Mg-Al hydrotalcite-like compound with a well-defined shape, distinct intercalated structure, regular quality, and good dispersing capability could be obtained under the following conditions: glycol volume ratio of 10%, hydrothermal temperature of 180 °C, and reaction time of 15 h. The compound obtained was well crystallized and had the morphology of a homogeneous and hexagonal sheet. The thickness of each hexagon in the hydrotalcite was about 40 nm, which was consistent with the value estimated with the Scherer equation.

The all-season real-time multivariate MJO (RMM) index was designed for an equal contribution of variance from the raw anomalous OLR and zonal winds at 850 (U850) and 200 hPa (U200), whereas it represents a notably larger proportion of the MJO variance in U850 and U200 than in OLR such that the index appears more dynamical and overestimates the MJO predictability and prediction skills. The revised RMM (RMM-r) substantially enhanced the fraction in OLR and reduced that in U850, whilst the distribution remains far from a balance. A new variant (RMM-b) is derived with the constraint of representing the same percentage (about 60.5%) of the globally total MJO variance in each field. The constraint determines 9 W m− 2, 2.73 m s− 1 and 4.1 m s− 1 to scale the OLR, U850 and U200, respectively, after the interannual variability is removed from the anomalies by a regression approach. The resultant RMM-b represents 30–40% more MJO power in OLR than the RMM, particularly at zonal wavenumbers 2–3 in eastward propagation and in the Western Pacific, and closer to the RMM-r. It carries 10–15% more MJO variance in U850 at zonal wavenumber 1 than the RMM-r, closer to the RMM. It detects the real-time MJO evolution closer to the RMM-r. And it discloses the MJO predictability and prediction skills in the recent Global Ensemble Forecasting System more reasonably than the RMM-r and closer to the RMM. The RMM-b is concluded to more suitably constitute the convectively coupled nature of the MJO.

Music colleges are a branch of our country’s colleges and universities, and campus informatization is a new development trend under the rapid development of network information technology today. Informatization is conducive to better campus management and administrative efficiency greatly improves. Compared with ordinary colleges and universities, the development of informatization construction in music and art colleges is relatively backward. Therefore, it is very necessary to customize a complete information campus construction plan specifically for music schools. This article will study the related issues of how to carry out information management in music academies based on the problems and practice of teaching management in music schools. Focus on the embedded multi-core processor storage system and propose new storage architecture based on the original. And through machine learning methods, artificial intelligence software that can recognize music styles is trained. Traditional recognition is relatively dependent on the listener’s experience. Cannot reach a complete standard, the accuracy rate is also unstable. So we use embedded application software under the premise of low power consumption. To achieve a stable and efficient way of listening to replace the traditional manual judgment.

The real-time multivariate Madden–Julian oscillation (RMM; MJO) index has been widely employed to monitor the amplitude, phase, and time evolution of MJO events, as the index is formulated from the leading two combined-empirical orthogonal function (CEOF) modes of daily anomalous OLR and 850- and 200-hPa zonal winds, and the modes describe the MJO dynamics well. These two CEOF modes, however, are known to dominate in power spectra at zonal wavenumber one and may underestimate the power and structure at wavenumbers 2–5 where many MJO events are also prominent. This study approximated a baseline for MJO by applying band-pass filters to daily anomalies on 30–100 day periods and at 1–5 eastward propagating waves, as slightly different bands led to the same conclusions. Following the procedures to develop the RMM index, the daily anomalous data were derived and subjected to the CEOF analysis with all modes archived for diagnosis. Different numbers of the leading modes were compared in explained variance, standard deviation (STD), and wavenumber power spectra to describe the overall MJO magnitude and structure, and on the Hovmöller diagrams to represent the evolution of three distinct MJO events. Results show that the two leading CEOF modes explain only a small portion of the power spectra at wavenumbers 2–5. This spectral leakage notably reduces the MJO amplitude, particularly of the OLR in the western Pacific. The CEOF modes 3–10 can withhold power sufficiently such that the anomalies reconstructed by the first 10 modes contribute most of the baseline variance; their structures agree well with the baseline by constituting nearly the same proportion in the region from the central Indian Ocean to the dateline and by providing more complete evolutions of the three MJO events on the Hovmöller diagrams. Meanwhile, these modes introduce a notable amount of power for the equatorial Rossby and Kelvin waves that are partially embedded in the evolution of MJO. The first 50 of the total 432 CEOF modes retain all variance of the baseline MJO, while those higher than 10 contain less information and more noise and can be discarded. Furthermore, this study indicated that the longitudinal STD of the reconstructed anomalies detects the MJO phases and magnitudes in the western Pacific with more physical meaning and in better agreement with the Hovmöller diagrams than the RMM-like amplitude. The results provide an integral figure of the MJO structure from the CEOF analysis and a more robust RMM framework for monitoring the MJO’s evolution in real time and for validating its numerical forecast and simulations.

Based on the resulting Lax pairs of the generalized coupled KdV soliton equation, a new Darboux transformation with multi-parameters for the generalized coupled KdV soliton equation is derived with the help of a gauge transformation of the spectral problem. By using Darboux transformation, the generalized odd-soliton solutions of the generalized coupled KdV soliton equation are given and presented in determinant form. As an application, the first two cases are given.

GIS technology was first introduced by Canadian surveyors. This technology was primarily used to digitize paper-based maps so that data can be analyzed and used on a computer that is convenient for distribution, storage, and use of information. Since GIS technology has been put forward, academic circles have been very interested. The growth of computer technology has also contributed to the development of GIS technology. GIS technology has now become a sophisticated topic that combines classification, storage, analysis, and performance of spatial information. Three-dimensional spatial knowledge can be realized by GIS technology. Spatial knowledge is often unique in real life, offering security for people’s clothes, food, housing, and transport. GIS technology also has great advantages in the processing of spatial information which makes GIS technology the most common application technology for spatial information processing and has been widely used in geological surveying, construction, and transport. In addition, the GIS framework can also be used to analyze atmospheric data. According to the results, the water content of the atmosphere can be measured in order to forecast precipitation and weather conditions. With the rapid advancement of computer technologies, GIS technology can be combined with the programming of databases. However, the progress of science and technology contradicts the principle of harmonious development between man and nature. Global warming caused by excessive carbon dioxide pollution is probably the most serious environmental issue.
