Purpose CmOS pixel sensor has become extremely attractive for future high-performance tracking *** has been proposed for the vertex detector at the Circular Electron Positron Collider,which will allow precision measurements of the properties of the Higgs *** meet the stringent requirements for low power consumption,it is necessary to optimize the pixel sensor diode geometry to reach a high charge-over-capacitance ratio that allows reduction in analog power *** Collection electrode size and footprint are two critical elements in sensor diode geometry and have deciding impacts on the charge collection performance.A prototype CmOS pixel sensor,named JadePix-1,has been developed with pixel sectors implemented with different electrode sizes and footprints,and its charge collection performance has been characterized with radioactive *** Charge-to-voltage conversion gains for pixel sectors under test have been calibrated with low-energy *** results have been obtained for equivalent noise charge(below 10e−),charge collection efficiency(around 40%),charge-over-capacitance ratio(above 0.015 V)and signal-to-noise ratio(higher than 55).Conclusion Small collection electrode size and large footprint are preferred to achieve high charge-over-capacitance ratio that promises low analog power *** studies on sensor performance before and after irradiation,combined with this work,will conclude the diode geometry optimization.

背景新生儿和幼儿对消旋布比卡因，即布比卡因的心肌毒性是否敏感一直存有争议。有的研究表明新生儿能耐受比成年人更高的血浆布比卡因浓度，而不产生严重的心肌毒性。本课题比较了大鼠不同鼠龄对消旋布比卡因和左旋布比卡因的心肌毒性的影响，并研究了上述局麻药对细胞内钙离子浓度的调节作用。方法给机械通气的2、4、6、8和16周龄的大鼠分别输注消旋布比卡因或左旋布比卡因[输注速度4mg／（kg·min）]，当监测显示心电活动停止时，所用剂量即定为该鼠龄大鼠的致死剂量。在应用外消旋布比卡因或内消旋布比卡因和不用此类局麻药时，分别以离体乳头肌颤搐测定方法研究局麻药对心肌收缩效应的影响。以裸露的心室肌纤维研究两种局麻药对细胞内钙离子浓度的调节作用。结果2周龄大鼠消旋布比卡因和左旋布比卡因的致死剂量（分别为46．0±5．2mg／kg和91．3±4．9mg／kg）均高于16周龄大鼠（分别为22．7±1．3mg／kg和22．0±2．7mg／kg）。乳头肌颤搐呈剂量相关性减低，且幼龄鼠心肌与成龄鼠心肌之间有显著性差异。在成龄鼠心肌，给予外消旋布比卡因后肌颤搐较对照减低8．6％±0．8％，而给予消旋布比卡因后肌颤搐较对照减低18．1％±2．7％（1001xm）。左旋布比卡因具有〈10μm的正性肌力效应，但仅见于2周龄大鼠。在裸露的心室肌纤维，消旋布比卡因和左旋布比卡因均能促使咖啡因（1mmol／L）激活的肌浆网释放钙离子增多，增加幅度相似，而此效应在幼龄鼠比成龄鼠更为明显。在16周龄大鼠，消旋布比卡因组咖啡因引起的反应是最大效应的53．9％±1．7％，而左旋布比卡因组为最大效应的54．1％±3．2％。在2周龄大鼠，消旋布比卡因组咖啡因引起的反应是最大效应的81．1％±3．7％，左旋布比卡因组为最大效应的78．1％±4．5％。在上两个消旋布比卡因和左旋布比卡因实验鼠龄组，收缩蛋白对钙离子的敏感性呈现同等程度的增加。肌浆网摄取钙离子并不因鼠龄或应用局麻药而发生变化。结论细胞内肌浆网钙离子调节机制的差异可能是幼龄鼠对消旋布比卡因和左旋布比卡因心肌抑制易感性减低的原因。

Using inclusive decays of J/ψ aprecise determination of the number of J/ψ events collected with the BESIII detector was *** the two data sets taken in 2009 and 2012,the numbers of J/ψ events were recalculated to be(224.0±1.3)×10^(6) and(1088.5±4.4)×10^(6),respectively;these numbers are in good agreement with the previous measurements. For the J/ψ sample taken in 2017-2019,the number of events was determined to be(8774.0±39.4)×10^(6).The total number of J/ψ events collected with the BESIII detector was determined to be(10087±44)×10^(6),where the uncertainty is dominated by systematic effects,and the statistical uncertainty is negligible.
