The Large Sky-Area Multi-Object Fiber Spectroscopic Telescope （LAMOST） Data Release 3 provided 341 691 K giant stars with stellar parameters. Based on the models of Law ＆ Majewski, we identified 252 K giant stars in the leading stream associated with the Sagittarius （Sgr） dwarf galaxy. We obtained 132 K giant stars belonging to the trailing arm of Sgr using the model of Belokurov et al. We studied the metallicity distribution of member stars along the streams and found a fiat gradient in the first wrap of the leading stream, -（0.88±0.3） × 10^-3 dex/（°） in the second wrap of the leading stream and -（1.2±0.3） × 10^-3 dex/（°） in the first wrap of the trailing stream. Moreover, we obtained a combined metallicity gradient with our sample and data from the literature. We also analyzed the properties of an overdensity, which is located in the leading stream of the Sgr.

Dasatinib is a second-generation tyrosine kinase inhibitor (TKI)and it could be used as a second-line treatment for patients with chronic myeloid leukemia (CML).Yinishu,a generic dasatinib made in China,was approved by the China Food and Drug Administration in 2013 and it costs much less than the patented dasatinib *** present study aimed to examine the efficacy and safety of Yinishu as a second-line treatment for CML by comparing the baseline clinical characteristics,rates of adverse events and efficacy between Yinishu and SPRYCEL groups. The results showed that there were no significant differences in the rates of optimal response between Yinishu and SPRYCEL for patients who started second-line treatment because of treatment *** patients who started second-line treatment because of intolerance of first-line treatment, their levels of BCR-ABL1/ABL1 on the international scale (BCR-ABL^IS)was maintained very low throughout the course of Yinishu ***-related adverse events occurred with the same frequency in these two *** was confirmed that Yinishu was effective and safe as a second- line treatment for CML *** may be more suitable for patients who are economically unable to pay for the patented dasatinib SPRYCEL.

This study evaluates the performance of CAMS-CSM(the climate system model of the Chinese Academy of Meteorological Sciences) in simulating the features, dynamics, and teleconnections to East Asian climate of the El Ni?o–Southern Oscillation(ENSO). In general, fundamental features of ENSO, such as its dominant patterns and phase-locking features, are reproduced well. The two types of El Ni?o are also represented, in terms of their spatial distributions and mutual independency. However, the skewed feature is missed in the model and the simulation of ENSO is extremely strong, which is found—based on Bjerknes index assessment—to be caused by underestimation of the shortwave damping effect. Besides, the modeled ENSO exhibits a regular oscillation with a period shorter than observed. By utilizing the Wyrtki index, it is suggested that this periodicity bias results from an overly quick phase transition induced by feedback from the thermocline and zonal advection. In addition to internal dynamics of ENSO,its external precursors—such as the North Pacific Oscillation with its accompanying seasonal footprinting mechanism, and the Indian Ocean Dipole with its 1-yr lead correlation with ENSO—are reproduced well by the model. Furthermore, with respect to the impacts of ENSO on the East Asian summer monsoon, although the anomalous Philippine anticyclone is reproduced in the post-El Ni?o summer, it exhibits an eastward shift compared with observation;and as a consequence, the observed flooding of the Yangtze River basin is poorly represented, with unrealistic air–sea interaction over the South China Sea being the likely physical origin of this bias. The response of wintertime lowertropospheric circulation to ENSO is simulated well, in spite of an underestimation of temperature anomalies in central China. This study highlights the dynamic processes that are key for the simulation of ENSO, which could shed some light on improving this model in the future.

本研究探讨了外部磁场对半导体量子点分子与腔光机械耦合系统中光学双稳态行为的影响.研究结果显示,外部磁场、量子点之间的隧穿耦合以及探测光单光子的失谐可以有效地调控系统的光学双稳态.在弱隧穿和弱磁场条件下,系统的光学双稳态阈值和磁滞回线宽度随着外部磁场和点间隧穿耦合强度的增加而增大.随着磁场强度和隧穿耦合强度的进一步增加,系统的双稳态将演变为多稳态.有趣的是,在强隧穿和强磁场作用下,系统的光学双稳态阈值和磁滞回线宽度随着外部磁场和点间隧穿耦合强度的增加而减小.这种对耦合腔光机械系统中光学双稳态的灵活调控将在可控光开关方面具有潜在的广泛应用前景.

The 40Cr steel matrix composites were reinforced with Al203 particulates （Al2O3p） through Si adding to improve the impact-abrasive wear resistance, in which Si powder ranging up to 25% of the AlzO3p weight was added into the Al2O3p preforms; then, the composites were fabricated by squeeze casting. For all composites, alumina particles are evenly distributed, and Si powder is dissolved in the matrix. Without Si powder addition, the 40Cr steel matrix contains only pearlite; however, ferrite appears and increases with Si powder addition. In the impact-abrasive wear tests, the impact frequency is 80 min^-1 and the impacting energy is 2 J. With increasing Si powder, the wear of the composites first decreases obviously, reaches the minimum at 10% and then increases. The effect of Si addition on the wear resistance can be attributed to two reasons： one is increasing the hardness of the matrix, and the other is improving the interfacial bonding between Al2O3p and steel. The wear mechanism of the composites is abrasive wear when the Si powder is 〈 10 wt%. Otherwise, it is a mixed mode of abrasive and delamination wear.

The two control methods, namely the general-control and the quadrature-control modes for HRG under force-rebalance mode were introduced firstly. Then the azimuth of antinode on the hemispherical resonator was deduced. The dynamics equations of resonator under the nonuniformity of density distribution were established by way of Bubonov-Galerkin method which is commonly used for solution of differential equations, and the state equation was established through the dynamics equations. The analytic solutions of the vibration displacement and the velocity were achieved by solving the state equation, and then the ratio of rebalance excitation to primary excitation was derived under the two working modes, thus the estimation of input angular rate of HRG were obtained. By comparing and calculating these two modes, the error caused by resonator's machining defects can be greatly inhibited under quadrature-control, and the fourth harmonic density error's tolerance were calculated to ensure the accuracy of HRG under these two modes.
