During the mining process of Hami open-pit coal mine, a large number of cracks appeared on the ground surface near the top of the end slope, which affected the stability of the slope and the subsequent safe mining of resources. By analyzing the deformation of rock stratum, the position of weak interlayer in the slope was determined. Considering the rock mass with weak interlayer as a complete mechanical system, the mechanical model of the rock mass system with weak interlayer was established, and the evaluation index of rock failure degree before slope instability was proposed. The failure mode of slope with weak interlayer is as follows: sliding failure-cutting layer failure-tension failure. The safety factor of slope decreases first and then increases with the increase of the depth of the weak interlayer, and gradually decreases with the increase of the inclination of the weak interlayer. The pressing foot of slope can be used in landslide control of slope with weak interlayers, and the optimal pressing foot solution to ensure the safe mining of final slope coal resources was determined to be a pressing foot height of 35 m and pressing foot width of 20 m.

To investigate the effects of electrolyzed watertreatment on the qualities of rice noodles prepared withsemidry- milled rice flour, pasting properties and thermalproperties of rice flour, and the cooking and texturalproperties of rice noodles were determined. Higher peakviscosity and lower melting enthalpy were observed inelectrolyzed water (EW) treated rice flour. The hardness,gumminess and chewiness of rice noodle in slightly acidicelectrolyzed water treated rice noodles with availablechlorine concentration (ACC) 20.32 mg/L were increasedsignificantly (p\0.05). The cooking loss decreased significantlyin strong acidic electrolyzed water treated noodleswith ACC 10.09 mg/L treatment (p\0.05). Theresults indicated that EW could promote the gelatinizationof rice flour, and improve the textural qualities of ricenoodles. Therefore EW was appropriate to be used in ricenoodle production.

Objective: To evaluate the prognostic factors of gallbladder carcinoma. Methods: Presentation, operative data, complications, and survival outcome were examined for 132 gallbladder carcinoma patients who underwent gallbladder surgery in our unit during 2002-2007, and follow-up results were obtained from every patient for univariate and multivariate survival analysis. Results: The univariate analysis showed that gallbladder lesion history, tumor cell differentiation, Nevin staging, preoperative lymph node metastasis and the surgical approach significantly correlated with the prognosis of the patients (p<0.05). The results of the multivariate analysis (Cox regression) showed that gallbladder lesion history, Nevin staging and the surgical approach were independent predicators with relative risks of 6.9, 4.4, 2.8, respectively (p=0.002, 0.003, 0.008). Conclusion: Gallbladder lesion history, Nevin staging and the surgical approach are independent prognostic factors for gallbladder carcinoma, a rapidly fatal disease. Therefore, early diagnosis, anti-infective therapy and radical surgery are greatly needed to improve the prognosis of gallbladder carcinoma.

This paper presents a fuzzy normal estimate for mass point clouds of irregular models in reconstruction. The irregular model is complex object that some part is smooth and some parts are irregular including sharp features. Therefore, we put kNN and curvature of mass point clouds to fuzzy inference system to divide the kind of point clouds and the output of FIS can determine which part of tooth point clouds belong to. For different kinds point clouds, corresponding algorithm is given. Point clouds in the smooth area are estimated normal by PCA directly and ones in other regions of thin or sharp area are estimated by checker and attach points. This method is simpler than those complex methods used on the whole point clouds directly. The experiment results show that much time is saved and surface reconstruction is very fine than PCA and WLOP.

Two known modified dipeptides, trichodermamide A (1) and aspergillazine A (2), were isolated from an ethyl acetate extract of the metabolite of a marine-derived fungus Spicaria elegans, and were found to have a weak cytotoxic effect on three cancer cell lines P388, A-549, and HL-60 agreed. To our knowledge, this is the first report on the isolation of compounds 1 and 2 from the fungus Spicaria elegans and their cytotoxic effect.

Sandstone has been regarded as an optimal medium for underground gas storage (UGS). To better understand effects of drying-wetting (D-W) cycles on creep behavior of sandstone, comprehensive experimental investigations including uniaxial compression test (UCT) and uniaxial constant-load creep test (UCCT), were conducted on sandstone specimens under different D-W cycles. Experimental results demonstrate that the UCS and E, instantaneous strain, and steady creep rate of sandstone are greatly influenced by D-W treatment. Steady creep rate of sandstone increases with the increase in stress and D-W cycles, while both the UCS and long-term strength (σ∞) of sandstone specimens gradually decrease with the increase in D-W cycles. A novel fractal derivative creep constitutive model of sandstone considering the variations of viscosity coefficient and D-W cycles is established, which could accurately describe the creep characteristics of sandstone after different D-W cycles in the whole creep process. The influence of D-W cycles on the sensitivity of creep parameters is analyzed to discuss the influence of D-W cycles on creep and damage behavior of sandstone.

The complete active space self-consist field method followed by the internally contracted multireference configuration interaction method has been used to compute the potential energy curves of X2Πg, a4Πu, A2Πu, b4Σ− g, and B2Σ− g states of S2 + cation with large correlation-consistent basis sets. Utilizing the potential energy curves computed with different basis sets, the spectroscopic parameters of these states were evaluated. Finally, the transition dipole moment and the Franck-Condon factors of the transition from A2Πu to X2Πg were evaluated. The radiative lifetime of A2Πu is calculated to be 887 ns, which is in good agreement with experimental value of 805 ± 10 ns.

Background and Purpose To examine the clinical and safety outcomes after endovascular treatment (EVT) for acute basilar artery occlusion (BAO) with different anesthetic modalities. Methods This was a retrospective analysis using data from the Endovascular Treatment for Acute Basilar Artery Occlusion (ATTENTION) registry. Patients were divided into two groups defined by anesthetic modality performed during EVT: general anesthesia (GA) or non-general anesthesia (non-GA). The association between anesthetic management and clinical outcomes was evaluated in a propensity score matched (PSM) cohort and an inverse probability of treatment weighting (IPTW) cohort to adjust for imbalances between the two groups. Results Our analytic sample included 1,672 patients from 48 centers. The anesthetic modality was GA in 769 (46.0%) and non-GA in 903 (54.0%) patients. In our primary analysis with the PSM-based cohort, non-GA was comparable to GA concerning the primary outcome (adjusted common odds ratio [acOR], 1.01; 95% confidence interval [CI], 0.82 to 1.25; <i>P</i>=0.91). Mortality at 90 days was 38.4% in the GA group and 35.8% in the non-GA group (adjusted risk ratio, 0.95; 95% CI, 0.83 to 1.08; <i>P</i>=0.44). In our secondary analysis with the IPTW-based cohort, the anesthetic modality was significantly associated with the distribution of modified Rankin Scale at 90 days (acOR: 1.45 [95% CI: 1.20 to 1.75]). Conclusion In this nationally-representative observational study, acute ischemic stroke patients due to BAO undergoing EVT without GA had similar clinical and safety outcomes compared with patients treated with GA. These findings provide the basis for large-scale randomized controlled trials to test whether anesthetic management provides meaningful clinical effects for patients undergoing EVT.
