studies of e^+e~→D_s^+■^((*)0)K^-and the P-wave charmed-strange mesons are performed based on an e^+e^-collision data sample corresponding to an integrated luminosity of 567 pb^(-1) collected with the BEsIII detector at s^(1/2)=4.600 GeV. The processes of e^+e^-→D_s^+■^(*0)K^- and D_s^+■~0K^- are observed for the first time and are found to be dominated by the modes D_s^+D_(s1)(2536)^-and D_s^+D_(s2)~*(2573)^-, respectively. The Born cross sections are measured to be σ~B(e^+e^-→D_s^+■^(*0)K^-) =(10.1±2.3±0.8) pb and σ~B(e^+e^-→D_s^+■~0K^-) =(19.4±2.3± 1.6) pb, and the products of Born cross section and the decay branching fraction are measured to be σ~B(e^+e^-→D_s^+D_(s1)(2536)^-+c.c.)·B(D_(s1)(2536)^-→■^(*0)K^-)=(7.5±1.8±0.7) pb and σ~B(e^+e^-→D_s^+D_(s2)~*(2573)^-+ c.c.)·B(D_(s2)~*(2573)^-→■~0 K^-)=(19.7 ± 2.9 ±2.0) pb. For the D_(s1)(2536)^-and D_(s2)~*(2573)^-mesons, the masses and widths are measured to be M(D_(s1)(2536)^-)=(2537.7±0.5 ±3.1) MeV/c2, Γ(D_(s1)(2536)^-) =(1.7 ±1.2 ±0.6)MeV, and M(D_(s2)~*(2573)^-)=(2570.7±2.0 ±1.7) MeV/c^2, Γ(D_(s2)~*(2573)^-)=(17.2 ±3.6 ±1.1) MeV. The spin-parity of the D_(s2)~*(2573)^-meson is determined to be J^p= 2^+. In addition, the processes e^+e^-→D_s^+■^((*)0)K^-are searched for using the data samples taken at four(two) center-of-mass energies between 4.416(4.527) and 4.575 GeV, and upper limits at the 90% confidence level on the cross sections are determined.

岩石学报 2000年第4期16卷 715-715页

作者： Andreas Audétat. 2000. Department of Geological sciences, Virginia Technology, Blacksburg, VA 24061, U.s.A. Department of Geological sciences Virginia Technology Blacksburg VA 24061 United States

Laser ablation ICP Ms is an extremely sensitive (yet destructive) analytical technique that allows major and trace elements to be quantified in fluid and melt inclusions as small as 10 μm. Individual inclusions are drilled out of their host mineral by using a laser beam (preferably 193 nm ArF Excimer laser), and the ablated material is continuously transported with an Ar/He gas mixture into the mass spectrometer (Günther and heinrich, 1999). The resulting transient signals are integrated and compared with signals obtained from standard glasses. The LA ICP Ms system at ETH Zürich (switzerland) allows up to 30 major and trace elements to be measured simultaneously, with detection limits typically being in the order of 10-100 ppm for a medium salinity, 30 μm sized inclusion (Günther et al ., 1998; Audétat et al ., 2000a,b). Main source of analytical uncertainty is the process of internal standardization, for which the absolute concentration of one element has to be estimated by an independent method. In case of fluid inclusions this is done by calculating Na from the total salinity (NaCl equiv ), and correcting this value for other major cations present in solution. The internal standardization of melt inclusions is based on Al, which is determined either by microprobe analysis of re homogenized inclusions, or is estimated from LA ICP Ms elemental ratios in conjunction with whole rock geochemical data. Examples of applications include: (i) geochemical evolution of hydrothermal fluids in ore deposits, (ii) metal fractionation between vapor and brine, and (iii) element partitioning between melt and aqueous fluid(s). LA ICP Ms analysis of successive generations of fluid inclusions in quartz crystals from the sn/W mineralized Mole Granite (Australia) demonstrates that ore precipitation was triggered by dilution of the magmatic fluid with meteoric water (Audétat et al ., 1998, 2000a). Partition coefficients determined on pairs of clearly cogenetic vapor and brine inclusions

妊娠期吸烟对胎儿和新生儿影响的新认识

德国医学 2000年第3期17卷 169-170页

在大多数工业发达的国家,吸烟被列为目前主要的但可以避免的致死原因。据'疾病监测中心'调查结果显示,1990年～1994年美国总计有超过200万的人死于吸烟,其中1/3是妇女,相当于同一时期死亡人数的20%。

Background: The anti-CD20 monoclonal antibody rituximab effectively depletes B lymphocytes and has been successfully used in the therapy of immune-mediated di sorders of the peripheral nervous system. A limited effect of rituximab on B lym phocytes in the cerebrospinal fluid compartment of patients with primary progres sive multiple sclerosis (Ms) was recently reported. Objective: To determine the effect of rituximab on clinical, magnetic resonance imaging, and immunological v ariables in a patient with relapsing-remitting Ms. Design: A patient with relap sing-remitting Ms was treated with rituximab. The patient was repeatedly examin ed clinically and by magnetic resonance imaging. The frequency of peripheral blo od and cerebrospinal fluid B lymphocytes was assessed by flow cytometry before, during, and after rituximab therapy. Results: Rituximab monotherapy resulted in significant clinical improvement. Inflammatory surrogate markers on magnetic res onance imaging were also reduced. B lymphocytes were depleted in the cerebrospin al fluid and peripheral blood. Conclusions: Our data demonstrate beneficial clin ical effects of rituximab in relapsing-remitting Ms, mediated through modulatio n of humoral systemic and central nervous system intrinsic immune responses. Cli nical trials should determine optimal therapeutic strategies for patients with r elapsing-remitting Ms.

A number of laser facilities coming online all over the world promise the capability of high-power laser experiments with shot repetition rates between 1 and 10 Hz. Target availability and technical issues related to the interaction environment could become a bottleneck for the exploitation of such facilities. In this paper, we report on target needs for three different classes of experiments: dynamic compression physics, electron transport and isochoric heating, and laser-driven particle and radiation sources. We also review some of the most challenging issues in target fabrication and high repetition rate operation. Finally, we discuss current target supply strategies and future perspectives to establish a sustainable target provision infrastructure for advanced laser facilities.

分期、恶性程度和多病灶出现,在表浅性膀胱癌是复发与进展的重要预后指标。进展是不可避免的,因此需相应的治疗措施。近百年来对各种疫苗对肿瘤的经过进行研究观察,通过对免疫系统的有目的刺激,可诱导出免疫反应发挥抗肿瘤作用。某些肿瘤内虽可见到一些免疫系统的细胞浸润,然而这种浸润与抗肿瘤作用的关系仍不明瞭;对效应细胞与抗肿瘤反应的机制所知也少。需要解决的是:最佳免疫治疗制剂、适宜剂量、使用间隔时间。
