具有水平对称轴的横向各向同性模型（HTI）已广泛地应用于横波分裂的研究中,用以描述具有互相平行形如多个硬币平行竖放的裂隙的简单的地层裂缝系统。在此,对水平层状HTI介质, 我们提出了一种对任意强度各向异性介质中长排列反射时差的解析描述。以正常时差（NMO）速度为参数的双曲线型正常时差方程对于常规的排列长度（接近于反射深度）的P波具有足够的精度。尽管Dix公式在偏离垂直对称平面时并不能严格成立,但我们的数值研究表明NMO层速度仍然可以由常规的Dix微分求得,并反演出各向异性参数。为了说明长排列情况下的非双曲线型时差,我们推导出了有关方位角的函数t2（x2）的四阶泰勒级数展开的精确表达式,它适用于单个HTI层中的任意非转换波型,对于多层HTI介质,四阶时差系数可以用已知的垂直横向各向同性条件下的均值方程来计算,它具有比较好的精度。这使我们能够将Tsvankin和Thomsen（1994）导出的垂直横向各向同性介质（VTI）中的非双曲线型时差方程扩展到具有很强方位各向异性的层状HTI模型中。由中等的和极强的非双曲线时差的介质的数值例子表明,这个方程精确地描述了HTI介质中P波的反射旅行时,即使排列长度达到反射面深度的两倍时亦如此。因此,同一方程可以有效地应用于由各向同性层、VTI层和HTI层任意组合形成的水平层状介质。此外,通过对非双曲线型时差内部特性的分析理解,这些结果可用于方位各向异性介质中反射旅行时的模拟和反演中。

Methicillin-resistant Staphylococcus aureus (MRSA) is a multi-drug resistant pathogen, which is responsible for increasing cases of serious diseases, including life-threatening diseases and nosocomial and community-acquired infections. Laboratory identification of MRSA is crucial and essential both for initiation of appropriate antimicrobial therapies and for effective infection control strategies that are designed to limit the spread of MRSA. In spite of the availability of commercial kits for MRSA detection in the market, the Clinical and Laboratory Standards Institute (CLSI) recommends the use of phenotypic methods, such as the disk diffusion method with oxacillin or with cefoxitin, as well as a serial dilution method with oxacillin. Nevertheless, some studies have shown that results obtained with such phenotypic methods are controversial. The aim of the study described in this paper was to comparatively evaluate the traditional susceptibility testing for MRSA with PCR as the gold standard assay. Analysis of collection (n = 68) isolates of Staphylococcus aureus revealed that the serial dilution method with oxacillin possessed the highest sensitivity (at 100%). In contrast, the disk diffusion methods with oxacillin and cefoxitin showed lower sensitivity (95.83%, 95% CI (78.81%-99.30%)). Furthermore, the borderline value of zone inhibition diameters for cefoxitin might be considered as a risk, and they may give false-susceptible result.

Three hundred and twenty endophytic actinobacterial strains were isolated from psammophytes collected from Taklamakan Desert and identified. Among them, three strains already had been identified as new species of two genera and sixteen isolates showed relatively low 16 S rRNA similarities < 98.6% to validly described species. Seventy-five of the isolates were selected as representative strains to screen antibacterial activity and mechanism. Forty-seven strains showed antagonistic activity against at least one of the indicator bacteria. Two Streptomyces strains produced bioactive compounds inducing DNA damage, and two Streptomyces strains produced bioactive compounds with inhibitory activity on protein biosynthesis. Notably, the strain Streptomyces sp. 8P21H-1 that demonstrated both strong antibacterial activity and inhibitory activity on protein biosynthesis was prioritized for exploring new *** the strategy of integrating genetics-based discovery program and MS/MS-based molecular networking, two new streptogramin-type antibiotics, i.e., acetyl-griseoviridin and desulphurizing griseoviridin, along with known griseoviridin, were isolated from the culture broth of strain 8P21H-1. Their chemical structures were determined by HR-MS, and 1D and 2D NMR. Desulphurizing griseoviridin and griseoviridin exhibited antibacterial activities by inhibiting translation.

This paper constructs and studies a nonlinear multivariate regression-tensor model for substantiation of necessary/sufficient conditions of optimization of technological calculation of multifactor physical and chemical process of hardening of complex composite media for metal coatings. An adaptive a posteriori procedure for parametric formation of the target quality functional of integrative physical and mechanical properties of the designed metal coating has been proposed. The results of the research may serve as elements of a mathematical language when creating automated design of precision nanotechnologies for surface hardening of complex composite metal coatings on the basis of complex tribological and anticorrosive tests.

目的研究P/Q型钙通道在小鼠海马神经元的突触传递中的重要作用。方法 1培养小鼠海马神经元用于研究,采用全细胞膜片钳记录技术,记录培养的对照组并趾症小鼠(oligosyndactyly,OS)和Leaner小鼠海马神经元钙离子电流;2刺激突触前细胞,记录突触后神经元抑制性突触后电流,观察对照组OS抑制性突触后电流对钙离子浓度的依赖性。3比较对照组OS和Leaner小鼠的突触后电流中各种钙通道在突触传递中所占比例。4转染长片段P/Q型质粒以恢复Leaner小鼠细胞因突变而引起的C末端过短所造成的功能缺失。结果 1抑制性突触后电流中P/Q型钙通道与钙浓度密切相关,在正常钙浓度的条件下,细胞外钙浓度为2mmol/L时,P/Q型钙通道起主要作用,当细胞外钙浓度升高到4mmol/L后,P/Q型钙通道功能所占比例部分由N型通道代替。2对照组OS和Leaner小鼠培养的海马神经元钙通道中P/Q型钙通道有很大的不同,突变小鼠中P/Q型钙通道功能减低,由其它通道补偿代替。3在培养的海马神经元记录的突触后电流显示Leaner小鼠的P/Q功能基本丧失,由N型和其他型所取代。4通过外源性转染含长片段P/Q型通道的质粒可以基本补偿P/Q型钙通道功能。结论 Leaner小鼠海马P/Q型钙通道功能降低是导致突触传递功能减少的重要因素。

Possible early diagnostic application of optical methods (dielectrophoresis, spectral and imaging ellipsometry, Fourier-transform infrared spectroscopy, Raman spectroscopy) in studies of red blood cells and serum of patients with diffuse liver disease with varying degrees of fibrosis has been evaluated. Application of combined optical methods was confirmed to significantly improve the performance of sensitivity, specificity, and accuracy index as well as to achieve the reliable results in diagnosis of both severe fibrosis and slight ulterior liver fibrosis. Identified diagnostic potential of optical methods can be effectively utilized in noninvasive screening evaluation of stages of diffuse liver disease of various geneses.
