The title compound 2-（4＇-methylphenoxy）-5,8,9-trimethyl-3-phenyl thieno[3＇,2＇：5,6] pyrido[4,3-d]pyrimidin-4（3H）-one hydrochloride （C26H23Cl4N3O2S, Mr = 583.33） has been determined by single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group P21/c with a = 14.8442（ 11 ）, b = 11.5131 （8）, c = 17.2010（13） A, β = 113.7250（10）°, V = 2691.3（3） ,A^3, Z = 4, Dc = 1.440 g/cm^3, S = 1.094,μ = 0.547 mm^-1, F（000） = 1200, the final R = 0.0571 and wR = 0.1458. X-ray analysis reveals that the title compound combines with a molecule of dichloromethane by an intramolecular hydrogen bond. The thienopyridine ring is almost coplanar, and the dihedral angle between the thiophene plane and the pyridine plane is 0.6°.

This paper studies the insurer’s solvency ratio model in a class of mixed fractional Brownian motion(MFBM) market, where the prices of assets follow a Wick-It? stochastic differential equation driven by the MFBM, by the method of the stochastic calculus of the MFBM and the pricing formula of European call option for the MFBM, the explicit formula for the expected present value of shareholders’ terminal payoff is given. The model extends the existing results.

Water soluble upconversion （UC） luminescence hexagonal-phase NaGdF4： yb3＋/Tm3＋ nanoparticles have been successfully synthesized by the hydrothermal method. XRD, SEM, UC photoluminescence spectra and electron paramagnetic resonance （EPR） spectrum were used to characterize the nanoparticles. The intensity of UC emission region could be controlled through different sodium source and the fluorine source, 6PJ→8S7/2 emission of Gd3＋ is also observed at 310 nm. A broad spectrum with a dominant resonance at g of about 2 was observed by the EPR spectrum of the NaGdF4：Yb3＋/Tm3＋ nanoparticles. The transparent NaGdF4：yb3＋/Tm3＋ solution presented naked eye-visible violet-blue light under the 980 nm LD excitation. The current work paves the way for their potential application in infrared tomography and magnetic resonance imaging （MRI）.

Sulfonate and/or phthalimidomethyl phthalocyanine zincs are obtained by the condensation reaction of anhydrous zinc acetate and two precursors, i.e. 4-phthalimidomethyl phthalonitrile and 4-(potassium sulfonated) phthalonitrile. The ZnPcSnPm mixture was separated into 5 components according to the number of substituted sulfonate groups and each component which has the same chemical constituent consists of different regioisomers. An HPLC method in isocratic conditions was developed to exercise quality control and make quantitative analysis of the photosensitizer, di-(potassium sulfonate)-di-phthalimidomethyl phthalocyanine zinc (abbreviated as ZnPcS2P2, here, S represents sulfonate group, P the phthalimidomethyl group and ZnPc the phthalocyanine zinc). Furthermore, by comparing the retention behavior of ZnPcS2P2 with that of ZnPcS2, positional structure of isomers of ZnPcS2P2 was speculated. Reversed-phase HPLC method with TEA-phosphate buffer and DMF as eluents in gradient conditions has been proved to be a powerful tool for the separation of such complex system.

To evaluate the longitudinal change in prostate-specific antigen （PSA） and the influence of initial PSA on the PSA change. We retrospectively analysed health examination data collected at Beijing Hospital from March 2007 to November 2011. Men with an initial PSA levels less than 4 ng ml- 1 and an annual PSA test for 5 years were enrolled into the study. The men were separated into four groups by the initial PSA level （0-0.99, 1-1.99, 2-2.99 and 3-3.99 ng ml- 1）, and the difference in PSA change among the four groups was analysed. A total of 1330 men were enrolled into the study. The mean age, initial PSA and PSA velocity （PSAV） were 58.17± 14.63 （range 24-91） years, 1.18±0.79 （range 0-4） ng m1-1 and 0.04±0.25 （range -1.34±2.02） ng m1-1 year-1, Pearson＇s correlation analysis showed no correlation between initial PSA and PSAV （r=-0.036, P=0. 189）. The PSAV of the 0-0.99, 1-1.99, 2-2.99 and 3-3.99 ng m1-1 initial PSA groups was 0.03±0.11, 0.07±0.32, 0.03±0.34 and -0.01±0.43 ng m1-1 year-1, respectively （P=0.06）. As the initial PSA increased, the percentage of having a PSAV over 0.75 ng m1-1 year-1 and a negative PSAV both significantly increased. Males with a baseline PSA of 0-0.99, 1-1.99, 2-2.99 and 3-3.99 ng ml- 1 had a 1.88%, 6.16%, 16.30% and 57.81% chance, respectively, that their PSA would increase above 4.0 ng ml- 1 over the following 4 years （P〈0.0001）. The PSAV has no correlation with the initial PSA level. However, as the initial PSA increases, the chance that males will have an abnormal PSA or PSAV in the future increases.

A systemic study was initiated to identify stage-specific expression genes in fish embryogenesis by using suppression subtractive hybridization (SSH) technique. In this study, we presented a preliminary result on screen for stage-specific expression genes between tail bud stage (TBS) and heartbeat beginning stage (HBS) in gynogenetic silver crucian carp (Carassius auratus gibelio). Two SSH plasmid libraries specific for TBS embryos and HBS embryos were constructed, and stage-specific expression genes were screened between the two stages. 1963 TBS positive clones and 2466 HBS positive clones were sampled to PCR amplification, and 1373 TBS and 1809 HBS PCR positive clones were selected to carry out dot blots. 169 TBS dot blot positive clones and 272 HBS dot blot positive clones were sequenced. Searching GenBank by using these nucleotide sequences indicated that most of the TBS dot blot positive clones could not be found homologous sequences in the database, while known genes were mainly detected from HBS d

During the Phase Ⅱ project of NSRL, a turn by turn BPM (Beam Position Monitor) system is proposedfor storage ring diagnostics which engages log-ratio electronics circuit to measure machine properties of the HLS(Hefei Light Source) storage ring. The log-ratio processor works at 408 MHz, twice the RF frequency of HLS. Mod-ern logarithmic amplifiers with wide dynamic range, great bandwidth, good logarithmic conformance, and low costare attractive for beam position measurements. Injection kicker and the stripline-electrode resonant exciting methodsare used to excite beam for nonlinear beam dynamics and phase space studies of stored beam. Up to 2 seconds of dataacquisition is ensured. In this paper we present the performance of each component and preliminary test results of theturn-by-turn BPM system.

In proxy signature schemes,the proxy signer B is permitted to produce a signature on behalf of the original signer A. However,exposure of proxy signing keys can be the most devastating attack on a proxy signature scheme since any adversary can sign messages on behalf of the proxy signer. In this paper,we applied Dodis,et al.’s key-insulation mechanism and proposed an Identity-Based (ID-based) Key-Insulated Proxy Signature (IBKIPS) scheme with secure key-updates. The proposed scheme is strong key-insulated and perfectly key-insulated. Our scheme also supports unbounded period numbers and random-access key-updates.

有限差分时间域正演是弹性波逆时偏移和全波形反演的基础,正演的计算精度也控制着偏移结果的准确性,若精度不高,则在偏移、反演后会带来假象.为了有效提高正演精度,本文结合窗函数优化方法,在窗函数截断伪谱法空间褶积序列以逼近有限差分算子的基础上,提出了一种基于Chebyshev窗的余弦调制模型,在原始Chebyshev窗的基础上引入了调制次数和调制范围,通过调节这两个参数可以人工可视化的调节截断误差,新的窗函数继承了Chebyshev窗的特点,在不明显降低截断谱范围的基础上明显降低了截断误差.本文针对不同正演阶数N,给出了一组经验调制系数,并通过数值模拟方法,对比了新方法、改进二项式窗和基于最小二乘优化方法的正演效果.结果表明,基于余弦调制的Chebyshev窗控制数值频散的能力更强,在大网格下可以得到更精确的正演结果.从经济角度分析,该方法减小了计算花费,提高了计算效率.

苏北盆地盘石山和方山新生代玄武岩中广泛发育橄榄岩包体,以尖晶石二辉橄榄岩为主,少数为尖晶石方辉橄榄岩。盘石山橄榄岩的岩相学特征表明其经历过Ol+Cpx+Melt=Ol+Opx+Melt的反应过程,而方山橄榄岩的这种反应过程不明显,表明古老的岩石圈地幔物质在方山下部仍有残留。与华北地块东部早古生代地幔橄榄岩相比较,本地区橄榄岩包体中橄榄石的Fo值为0.89～0.90,斜方辉石的En值为0.88～0.90,表现为饱满玄武质组分的特点,表明从早古生代至新生代期间经历了岩石圈的减薄和岩石圈地幔的置换。平衡温压估算结果表明,方山橄榄岩平衡温度为985℃～1 081℃,平衡压力为1.65 GPa～2.61 GPa,对应的深度为53 km～84 km;盘石山橄榄岩平衡温度为940℃～1 010℃,平衡压力为0.90 GPa～2.07 GPa,对应的深度为29 km～66 km。盘石山橄榄岩包体的起源深度小于方山,苏北盆地新生代时期岩石圈地幔的厚度约为50 km,位于岩石圈30 km～80 km之间。
