| 1 | 1→N quantum controlled phase gate realized in a circuit QED system显示文摘We propose an effective method to realize the quantum phase gate of one qubit simultaneously controlling N qubits. We use the system in which the transmon qubits are capacitively coupled to a superconducting transmission line resonator driven by a strong microwave field. In our scheme, the phase gate can be realized in a time (nanosecond-scale) much shorter than decoherence time (microsecond-scale), and it is more immune to the 1/f charge noise and has longer dephasing time due to the favorable properties of the transmon qubits in the system. | GAO GuiLong CAI GenChang HUANG.ShouSheng TANG LongYing GU WenJing WANG MingFeng JIANG-NianQuan | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，8： | 4 |
| 2 | Second-trimester maternal β-human chorionic gonadotropin level associated with subsequent development of pregnancy-induced hypertension显示文摘Objective:To determine whether maternal β-human chorionic gonadotropin(β-hCG) level in second-trimester may be associated with subsequent development of pregnancy-induced hypertension(PIH).Methods:Seven hundred and sixty-two women in mid-trimester were to have maternal urine β-hCG standardized concentrations and maternal serum β-hCG measurements.Their case histories were recorded and reviewed from mid-trimester to delivery.The relation was observed between maternal urine,serum markers and subsequent development of PIH.Results:Among 762 women,504 cases were normal pregnancies,42 cases had PIH,94 cases had premature rupture of membrane (PROM),69 cases had preterm delivery (PD),53 other cases were excluded by various reasons.The levels of maternal urine,serum β-hCG in PIH were (61.75±9.78) IU/L and (304.56±54.17) ng/mg respectively,which were higher significantly than normal pregnancy group ([20.65±7.61] IU/L and [146.34±47.81] ng/mg,P<0.05).When maternal serum,urine β-hCG levels ≥2 MOM(multiple of mean),the incidences of developing PIH were increased significantly as compared with those of β-hCG <2 MOM women.The incidence of PIH increased from 5.1% in pregnancies with urine β-hCG ≥2 MOM to 11.7% in cases with urine β-hCG ≥4 MOM.Conclusion:The elevation of maternal mid-trimester urine,serum β-hCG levels is not only an early signal for dysfunction of placenta but also a dangerous signal for development of PIH.Second-trimester maternal urine β-hCG measurement proves to be superior to serum marker in clinical prediction. | Tang Longying Chen Qizhen Zuo Wanxin Sun Tingwei Wang Yianshu Jin Hua | 2010 | Journal of Medical Colleges of PLA(China)2010，25，5： | 2 |
| 3 | Seasonal variation of foliar δ^(13)C values and its indictor significance in Sabina przewalskii and Sabina chinensis显示文摘Seasonal variation of foliar δ13C values as well as proline,silicon,MDA and relative water content in Sabina przewalskii Kom.and S.chinensis (Lin.) Ant.were measured.The results show that foliar δ13C values were significantly different at different seasons:lower in winter but higher in summer.δ13C values were positively correlated with air temperature and soil temperature.This demonstrates that foliar δ13C of Sabina is a successful empirical indictor of temperature.Furthermore,foliar δ13C values were positively related to proline and silicon content,and negatively related to relative water content and MDA content.Compared with S.chinensis,S.przewalskii has higher δ13C values,proline and silicon content as well as lower MDA and relative water content.All these results provided strong evidence that it is feasible for δ13C to be regarded as another index to evaluate freezing tolerance of Sabina. | Tuo Chen HuiJuan Pei YouFu Zhang LongYing Wen HongGuan Tang YuanQing He | 2011 | Research in Cold and Arid Regions2011，3，2： | 0 |
