We investigate the level of galaxy assembly bias in the Sloan Digital Sky Survey (SDSS) main galaxy sample using ELUCID,a state-of-the-art constrained simulation that accurately reconstructed the initial density perturbations within the SDSS *** top of the ELUCID haloes,we develop an extended hOD model that includes the assembly bias of central and satellite galaxies,parameterized as Q_(cen)and Q_(sat),respectively,to predict a suite of one-and two-point *** particular,our fiducial constraint employs the probability distribution of the galaxy number counts measured on 8 h^(-1)Mpc scales N_8^(g) and the projected cross-correlation functions of quintiles of galaxies selected by N_(8)^(g) with our entire galaxy *** perform extensive tests of the efficacy of our method by fitting the same observables to mock data using both constrained and non-constrained *** discover that in many cases the level of cosmic variance between the two simulations can produce biased constraints that lead to an erroneous detection of galaxy assembly bias if the non-constrained simulation is *** applying our method to the SDSS data,the ELUCID reconstruction effectively removes an otherwise strong degeneracy between cosmic variance and galaxy assembly bias in SDSS,enabling us to derive an accurate and stringent constraint on the *** fiducial ELUCID constraint,for galaxies above a stellar mass threshold M_(*)=10^(10.2)h^(-2)M_(⊙),is Q_(cen)=-0.09±0.05 and Q_(sat)=0.09±0.10,indicating no evidence for a significant (>2σ) galaxy assembly bias in the local Universe probed by ***,our method provides a promising path to the robust modelling of the galaxy-halo connection within future surveys like DESI and PFS.

为降低高沉积率激光金属沉积(Laser Metal Deposition,LMD)工艺中材料的孔隙率,研究了以镍基高温合金Inconel 718(IN718)为粉末沉积材料的高沉积率LMD工艺中主要工艺参数对材料孔隙率的影响,以及通过调整工艺参数降低材料孔隙率的方法。以目标沉积率为2kg/h的LMD工艺为基础,通过参数固化和分离的手段开展了高沉积率LMD的镀层实验,研究了主要工艺参数即激光功率、扫描速度及送粉量对LMD镀层材料孔隙率的影响,分析了不同参数下各镀层的横截面孔隙率及镀层孔隙率。实验显示:当激光功率从1 440 W增加到4 214 W时,镀层材料的孔隙率从约1.5%降低至0.02%左右;当扫描速度为500mm/min至5 000mm/min时,镀层材料孔隙率始终保持为0.07%至0.18%左右;当送粉量从0.64kg/h增加至6.48kg/h时,镀层材料孔隙率从约0.01%增加至0.84%左右。可见在高沉积率LMD工艺中,扫描速度对材料孔隙率无明显影响,而提高激光功率、限制送粉量均可有效降低LMD材料孔隙率,提高横截面孔隙率的一致性。

Investigation of Galactic open cluster remnants： the case of NGC 7193

Galactic open clusters （OCs） that survive the early gas-expulsion phase are gradually de- stroyed over time by the action of disruptive dynamical processes. Their final evolutionary stages are characterized by a poorly populated concentration of stars called an open cluster remnant （OCR）. This study is devoted to assessing the real physical nature of the OCR candidate NGC 7193. GMOS/Gemini spectroscopy of 53 stars in the inner target region were obtained to derive radial velocities and at- mospheric parameters. We also employed photometric and proper motion data. The analysis method consists of the following steps：（i） analysis of the statistical resemblance between the cluster and a set of field samples with respect to the sequences defined in color-magnitude diagrams （CMDs）; （ii） a 5-dimensional iterative exclusion routine was employed to identify outliers from kinematical and posi- tional data; （iii） isochrone fitting to thes× （J - Ks） CMD of the remaining stars and the dispersion of spectral types along empirical sequences in the （J - h） × （h - Ks） diagram were checked. A group of stars was identified for which the mean heliocentric distance is compatible with that obtained via isochrone fitting and whose metallicities are compatible with each other. Fifteen of the member stars observed spectroscopically were identified together with another 19 probable members. Our results indi- cate that NGC 7193 is a genuine OCR, of a once very populous OC, for which the following parameters were derived： d = 501±46 pc, t = 2.5±1.2 Gyr, （[Fe/h]） = -0.17±0.23 and E（B-V） = 0.05±0.05. Its luminosity and mass functions show depletion of low mass stars, confirming the OCR is in a dynam- ically evolved state.

目的:研究RGK家族中Rem微小蛋白对胚胎小白鼠心室肌细胞Ca^(2+)通道功能的影响。方法:用含有相同浓度正常的Rem(Ad-RemWT)和反转的Rem蛋白(Ad-CTRrem)的两组重组腺病毒(1012/ml)分别感染培养的怀孕18d胚胎小白鼠(ED18)心室肌细胞。12h后,用整个细胞的电压嵌技术来记录ED18心室肌细胞膜L-型Ca^(2+)电流,细胞质Ca^(2+)转运用荧光光度测定法测定。结果:Rem可以很好地在ED18心室肌细胞中表达。在整个细胞的电压嵌技术下,对照组(Ad-CTRrem)能记录到L-型Ca^(2+)电流的细胞为83·3%,实验组(Ad-Rem-WT)为6·6%。Rem有效阻断了ED18心室肌细胞膜Ca^(2+)通道电流。通过荧光光度测定法,测定Rem显著减低了ED18心室肌细胞质Ca^(2+)的转运。结论:外源的RGK家族中Rem蛋白的表达,通过与心室肌细胞Ca^(2+)通道蛋白的β亚单位(Cavβ)相结合改变了Ca^(2+)通道功能,限制了Ca^(2+)的内流。

Silicon(Si)photonics has recently emerged as a key enabling technology in many application fields thanks to the mature Si process technology,the large silicon wafer size,and promising Si optical *** monolithic integration by direct epitaxy of III-V lasers and Si photonic devices on the same Si substrate has been considered for decades as the main obstacle to the realization of dense photonics *** considerable progress in the last decade,only discrete III-V lasers grown on bare Si wafers have been reported,whatever the wavelength and laser *** we demonstrate the first semiconductor laser grown on a patterned Si photonics platform with light coupled into a waveguide.A mid-IR GaSb-based diode laser was directly grown on a pre-patterned Si photonics wafer equipped with SiN waveguides clad by SiO_(2).Growth and device fabrication challenges,arising from the template architecture,were overcome to demonstrate more than 10 mw outpower of emitted light in continuous wave operation at room *** addition,around 10%of the light was coupled into the SiN waveguides,in good agreement with theoretical calculations for this butt-coupling *** work lft an important building block and it paves the way for future low-cost,large-scale,fully integrated photonic chips.
