Time-lapse geophysical technology-based study on overburden strata changes induced by modern coal mining

To study the impact of modern coal mining on overlying strata and its water bearing conditions,integrated time-lapse geophysical prospecting integrating 3D seismic,electrical and ground penetrating radar method were used.Through observing and analyzing the geophysical data variations of all stages of pre-mining,mining and post-mining as well as post-mining deposition stable period,impacts of coal mining on stratigraphic structure and its water bearing were studied and modern coal mining induced stratigraphic change pattern was summarized.The research result shows that the stratigraphic structure and the water bearing of surface layer during modern coal mining have self-healing pattern with mining time;the self-healing capability of near-surface strata is relatively strong while the roof weak;water bearing selfhealing of near-surface strata is relatively high while the roof strata adjacent to mined coal beds low.Due to integrated time-lapse geophysical prospecting technology has extra time dimension which makes up the deficiency of static analysis of conventional geophysical methods,it can better highlight the dynamic changes of modern coal mining induced overburden strata and its water bearing conditions.

Influence of Initial Value of Transient Time Step on Numerical Simulation of Blow Molding Balloon

The correlation between the initial time value of transient iterative parameters and the blowing pressure in the numerical simulation process of blowing balloon is investigated by POLYFLOW. The results show that: 1) As the blow molding pressure increases, the boundary value of the iterative time step decreases rapidly at first and then slowly. At the end of the first step of iterative calculation for each boundary value, the balloon parison is in the mold core cavity. 2) If the initial time value of transient iterative parameters is smaller than the boundary value of the iterative time step, the balloon parison is still in the mold core cavity at the end of the first iteration. However, if the iterative calculation continues, the calculation process may be interrupted when the time step is smaller than the initial time value of the transient iterative parameters, which makes the blow molding simulation of balloon unable to continue. 3) It is suggested that the initial time value of transient iterative parameters is one order of magnitude smaller than the boundary value of the iterative time step to complete smoothly the simulation of blow molding balloon.

Reconstruction of time series with missing value using 2D representation-based denoising autoencoder

Time series analysis is a key technology for medical diagnosis,weather forecasting and financial prediction systems.However,missing data frequently occur during data recording,posing a great challenge to data mining tasks.In this study,we propose a novel time series data representation-based denoising autoencoder(DAE)for the reconstruction of missing values.Two data representation methods,namely,recurrence plot(RP)and Gramian angular field(GAF),are used to transform the raw time series to a 2D matrix for establishing the temporal correlations between different time intervals and extracting the structural patterns from the time series.Then an improved DAE is proposed to reconstruct the missing values from the 2D representation of time series.A comprehensive comparison is conducted amongst the different representations on standard datasets.Results show that the 2D representations have a lower reconstruction error than the raw time series,and the RP representation provides the best outcome.This work provides useful insights into the better reconstruction of missing values in time series analysis to considerably improve the reliability of timevarying system.

Lotic specialization in modern Asian newts(Caudata:Salamandridae):Phylogeny,historical biogeography,and ancestral traits based on combined DNA data

Pachytriton,and Paramesotriton,are primarily distributed across East Asia,displaying a broad range of environmental adaptations,including generalists inhabiting both lotic and lentic habitats and lotic specializations.Despite recent studies on their biogeographic history,how these species adapted to geographical changes remains unclear.In this study,divergence times and reconstructed ancestral traits were estimated based on phylogenetic analysis of mitochondrial and nuclear DNA sequences,totaling 4048 bp.Results indicated that the divergence between lotic-specialized and generalist species occurred during the middle to late Miocene(95% confidence interval(CI):16-13 million years ago(Ma)),correlating with the long-lasting arid period(14-12 Ma)and uplift of the Wuyi-Nanling mountains(15-11 Ma).Ancestral trait reconstruction revealed notable morphological changes associated with the emergence of lotic-specialized lineages.Specifically,male body size increased from 130 mm to 140 mm,and epibranchial traits shifted from thin to thick structures.Additionally,variation in tongue movability and skin texture were observed among lotic species.Each morphological shift is hypothesized to have an ecological basis,facilitating adaptation to specific environmental conditions.Overall,this study represents the first comprehensive attempt to elucidate the evolution of ancestral traits among divergent species of modern Asian newts,providing a deeper understanding of their adaptive responses to historical geographical and climatic changes.

Determining the time and space domains forestimating b value in seismic zoning

To take the seismic zone that includes the great shock with M S8.5 as the statistical unit of estimating b value can often lead to more large variance, because the seismogenic zone of the great shock with M S8.5 are larger than that delineated in general seismic zone. Two-level statistical units are considered in this paper. The seismic province is the first level unit that is suitable for group of earthquakes including the great shock of M S8.5. A seismic province can be divided into several seismic zones. They can be taken as the second level unit for group of quakes in which the super magnitude of the greatest shock do not exceed 8. Because of the nonstationarity in time of seismic activity, the unbalancedness of data and differential of seismic temporal series feature in different areas need to be considered when we select the time period for estimating b value. According to local conditions, the time period is selected at one′s discretion in order to reflect seismicity level of this statistical unit in future 100 years.

Estimation of Dynamic VaR in Chinese Stock Markets Based on Time Scale and Extreme Value Theory

The accuracy and time scale invariance of value-at-risk （VaR） measurement methods for different stock indices and at different confidence levels are tested. Extreme value theory （EVT） is applied to model the extreme tail of standardized residual series of daily/weekly indices losses, and parametric and nonparametric methods are used to estimate parameters of the general Pareto distribution （GPD）, and dynamic VaR for indices of three stock markets in China. The accuracy and time scale invariance of risk measurement methods through back-testing approach are also examined. Results show that not all the indices accept time scale invariance; there are some differences in accuracy between different indices at various confidence levels. The most powerful dynamic VaR estimation methods are EVT-GJR-Hill at 97.5% level for weekly loss to Shanghai stock market, and EVT-GARCH-MLE （Hill） at 99.0% level for weekly loss to Taiwan and Hong Kong stock markets, respectively.

Value and Development Countermeasures for Modern Agriculture in Suzhou

With advance of urbanization and industrialization, modern agricultural development in Chinas economic developed areas (CEDAs) is greatly restricted by traditional concept. To speed up the development of modern agriculture in CEDAs, this paper takes Suzhou City as an example from theories supporting modern agricultural development. It demonstrates agriculture in CEDAs plays an important role in adjusting supply of agricultural and sideline products, reserving rural labor employment, protecting ecological environment, increasing farmers income, and passing on agricultural culture. It contends that CEDAs should take reserving basic farmland as prerequisite; take adequate supply of primary agricultural products, protection of living environment, maintenance of agricultural landscape, and inheritance of farming culture as objectives; establish perfect modern agricultural system through firmly setting up modern agricultural value concept; increase local public finance input; increase agricultural functional value from technical and management levels, to realize increase of farmers income, promote sustainable development of agriculture, promote integrated urban and rural development, as well as harmonious development of human and nature.

On the Feminist Comparative Study of Views on Marriage Between the Early Nineteenth Century and Modern Times—Taking Pride and Prejudice for Example

Marriage is a theme influenced by cultural progress. Economic factor is one of the main elements that people of the early nineteenth century considered when deciding a marriage. The pursuit of economic interest results in the advent of some tragic marriages while now it is a side reason. However, women today have made great advancement in education background, employment situation and social status. Women gradually have their economic ability, autonomy and social status. Hence, they began to lay emphasis on the equality and sense of happiness. This is why the views on marriage vary in different eras. This paper, based on the view of marriage from the nineteenth- century English novel Pride and Pejudice, is dedicated to elucidating the changes and improvements of view on marriage from feminist perspective via comparing and contrasting the similarities and the differences of people's view on marriage between the early 1800 s and modern times, and then draws a conclusion that the women's degree of receptive education can influence their social status and view on marriage. In modern times the view on marriage based on equality attribute to the sense of happiness of a family and the degree of satisfaction of marriage.

Optimizing Time-Spectral Solution of Initial-Value Problems

Time-spectral solution of ordinary and partial differential equations is often regarded as an inefficient approach. The associated extension of the time domain, as compared to finite difference methods, is believed to result in uncomfortably many numerical operations and high memory requirements. It is shown in this work that performance is substantially enhanced by the introduction of algorithms for temporal and spatial subdomains in combination with sparse matrix methods. The accuracy and efficiency of the recently developed time spectral, generalized weighted residual method (GWRM) are compared to that of the explicit Lax-Wendroff and implicit Crank-Nicolson methods. Three initial-value PDEs are employed as model problems;the 1D Burger equation, a forced 1D wave equation and a coupled system of 14 linearized ideal magnetohydrodynamic (MHD) equations. It is found that the GWRM is more efficient than the time-stepping methods at high accuracies. The advantageous scalings Nt<sup style="margin-left:-6px;">1.0Ns<sup style="margin-left:-6px;">1.43 and Nt<sup style="margin-left:-6px;">0.0Ns<sup style="margin-left:-6px;">1.08 were obtained for CPU time and memory requirements, respectively, with Nt and Ns denoting the number of temporal and spatial subdomains. For time-averaged solution of the two-time-scales forced wave equation, GWRM performance exceeds that of the finite difference methods by an order of magnitude both in terms of CPU time and memory requirement. Favorable subdomain scaling is demonstrated for the MHD equations, indicating a potential for efficient solution of advanced initial-value problems in, for example, fluid mechanics and MHD.

A Living Buddha of Modern Times

Entering any Tibetan Buddhist monastery one may feel overwhelmed, struck with awe. But the worshipping seems much more pleasant at the Sepa Monastery which is hidden in deep mountains on the right bank of Tongtian River—the upper reach section of the Yangtze, in Yushu Tibetan Autonomous Prefecture of Qinghai Province. A closer observation can tell that the pleasant feeling comes from the brightness inside the main hall of the monastery, as well as from the lush woods around its buildings, which present a sweet greenness rarely seen
