The an thors developed a new composite cement base material by mixing the high tenacity polypropylene （coarse） fiber in plain cement base for the cement-layer-spray technology. By studying the key parameters of the fiber dosage, the spray layer thickness, and the fiber reinforced concrete injection time, etc. It is found that the ideal volume ratio of polypropylene （crude） fiber is 0.8% （V/V）, and the secondary lining fiber concrete spraying should start when the shrinkage rate is lower than 0.5 mm/d, and the optimal thickness of shotcrete is 120 mm. The supporting effects and the economic benefits were studied using a real project practice, and the result obtained can be a good reference for practical applications of this new supporting material in the future.

The problems of determining the spectrality or non-spectrality of a measure have been received much attention in recent years. One of the non-spectral problems on μM,D is to estimate the number of orthogonal exponentials in L2(μM,d). In the present paper, we establish some relations inside the zero set dit_***" width="55" height="23" alt="" /> by the Fourier transform of the self-affine measure μM,d. Based on these facts, we show that μM,d is a non-spectral measure and there exist at most 4 mutually orthogonal exponential functions in L2(μM,d), where the number 4 is the best possible. This extends several known conclusions.

To examine the procoagulant effects of thrombolytic agent on h emostasis and study the role of hemostatic markers as predictors of clinical outcomes. Methods. In the present study, eighteen patients with acute myocardial in farction(AMI) received 1.5 or 2.0 million U nonspecific urokinase(UK), or 70～80 mg fibrin specific recombinant tissue plasminogen activator(rt PA)and did not use heparin until 8 hours after intravenous injection of the above agents. Eig ht patients with AMI and without thrombolytic therapy were enrolled as controls. Coagulant and thrombolytic activity markers included thrombin antithrombin Ⅲ complex (TAT), d dimer, fibrinogen (Fg), FMPV/Amax. All markers were determined before,immediately,1,2,4 and 8 hours after the administration of thrombolytic a gents respectively. Results. Molecular marker of thrombin generation——TAT showed an activated coa gulant state immediately after thrombolytic therapy. Level of TAT showed no sign ificant changes between every two observed phases in controls. However, level of TAT increased significantly from 4.95±1.75μg/L ( 4.63±1.37μg/L) to 14.71±3 .31μg/L ( 14.25±2.53μg/L) before and immediately after administration of thro mbolytic agents UK(or rt PA). There was significant difference between level of serum TAT of patients with and without thrombolytic therapy (Png clinical reperfusion had lower TAT level than those failing in thromb olytic therapy, and higher FMPV/Amax level than controls. d dimer, a surrogate of thrombolytic activity increased markedly and Fg significantly declined afte r thrombolytic therapy(Pd in plasma in response to excess fibri nolysis induced by thrombolytic therapy.

Two different CdⅡ coordination frameworks [Cd(L1)(L2)]∞(1) and [Cd(L1)-(L3)(H2O)]∞(2) based on a flexible dicarboxylic acid ligand were obtained by introducing two different nitrogen heterocyclic auxiliary ligands(L1 = 3,3’-[1,3-benzenebis(carbonylimino)]bi(benzoate), L2 = 1,3-bi(4-pyridyl)propane, L3 = 4,4’-bipyridine). Complex 1 crystallizes in triclinic, space group P■ with a = 8.7415(5), b = 12.2247(7), c =16.2415(10) ?, β = 95.6790(10)°, V = 1525.11(16) ?3, dc = 1.553 mg·m-3, C35H28CdN4O6, Mr = 713.02, F(000) = 724, μ(MoKα) = 0.770 mm–1, Z = 2, R/wR(I > 2σ(I))a = 0.0302/0.0773. However, complex 2 crystallizes in monoclinic, space group P21/n with a = 11.4986(7), b = 23.0911(14), c = 11.9943(8) ?, β = 115.9500(10)°, V = 2863.6(3) ?3, dc = 1.598 mg·m-3, C32H24CdN4O7, Mr = 688.96, F(000) = 1392, μ(MoKα) = 0.820 mm–1, Z = 4, R/wR(I > 2σ(I))a = 0.0283/0.0631. The structures of two complexes were characterized. Complexes 1 and 2 have different one-dimensional(1d) chain structures. In addition, we have also made a preliminary study on the properties of the two complexes.

This paper presents a generic procedure to implement a scalable and high performance data analysis framework for large-scale scientific simulation within an in-situ infrastructure. It demonstrates a unique capability for global Earth system simulations using advanced computing technologies (i.e., automated code analysis and instrumentation), in-situ infrastructure (i.e., AdIOS) and big data analysis engines (i.e., SciKit-learn). This paper also includes a useful case that analyzes a globe Earth System simulations with the integration of scalable in-situ infrastructure and advanced data processing package. The in-situ data analysis framework can provides new insights on scientific discoveries in multiscale modeling paradigms.

This study quantifies the main characteristics of a terrain-following, G-coordinate through mathematical analyses of its covariant and contravariant basis vectors as well as the vertical coordinate of σ. A 3-d schematic of the σ-coordinate in a curvilinear coordinate system is provided in this study. The characteristics of the basis vectors were broken down into their ＂local vector charac- teristics＂ and ＂spatial distribution characteristics＂, and the exact expressions of the covariant; in addition, the con- travariant basis vectors of the G-coordinate used to eluci- date their detailed characteristics were properly solved. Through rewriting the expression of the vertical coordi- nate of G, a mathematical expression of all the cr-coor- dinate surfaces was found, thereby quantifying the so- called terrain-following characteristics and lack of flexi- bility to adjust the slope variation of G-coordinate sur- faces for the classic definition of G. Finally, an analysis on the range value of the vertical coordinate demonstrated that the general value range of G could be obtained by eliminating the G-coordinate surfaces below the Earth＇s surface. All these quantitative descriptions of the charac- teristics of G-coordinate were the foundation for improv- ing the G-coordinate or creating a new one.
