The plasma current ramp-up is an important process for tokamak discharge,which directly affects the quality of the plasma and the system resources such as volt-second consumption and plasma current *** China Fusion Engineering Test Reactor(CFETR)ramp-up discharge is predicted with the tokamak simulation code(TSC).The main plasma parameters,the plasma configuration evolution and coil current evolution are given *** the same time,the volt-second consumption during CFETR ramp-up is analyzed for different plasma shaping times and different plasma current ramp rates dIP/dt with/without assisted *** results show that the earlier shaping time and the faster plasma current ramp rate with auxiliary heating will enable the volt-second to save 5%-10%.At the same time,the system ability to provide the volt-second is probably 470 V·*** simulations will give some reference to engineering design for CFETR to some degree.

Objective To investigate the effect of n-butanol extract from Potentilla anserina(NP)intervention on hypoxia-induced Ca 2+ overload and SERCA2 expression of rat *** Primary cultured myocardial cell from SD neonatal rat(1-3 d)was used in the establishment of hypoxia *** hypoxia for 3 h,the Ca 2+ concentration of myocardial cells was measured with fura-2/AM fluorescent probe,and the biochemical indicator intracellular Ca 2+ -ATPase was examined and the mRNA and its protective protein levels of the sarcoplasmic reticulum(SR)Ca 2+ -ATPases(SERCA2)were assayed with RT-PCR,Western-blotting,and immune-cytochemical staining in each *** The results showed that NP decreased Ca 2+ concentration, increased the activity of Ca 2+ -ATPase,and improved the mRNA and protein expression of SERCA2 in hypoxia-injured myocardial cells as compared with the model *** These results indicate that NP could attenuate the Ca 2+ *** mechanism might be explained as that NP could elevate the SERCA2 level, increase the activity of myocardium in rats,and further enhance the capacity of SR Ca 2+ re-uptake.

针对频分双工大规模多输入多输出(Multiple-Input Multiple-Output,MIMO)通信系统中信道状态信息(Channel State Information,CSI)反馈方法复杂度高、精度低和开销大的问题,本文提出了一种基于深度学习的低复杂度CSI反馈方法.该方法通过端到端的方式构建了一种从用户设备编码器到基站解码器相结合的网络结构.编解码器利用连续的平均池化层和上采样层完成特征图的降维和升维,同时引入深度可分离卷积神经网络减少网络参数量.在解码器部分,本文利用残差网络构建连续的拥有大卷积核的残差块逼近原始CSI矩阵.仿真结果表明,和已有的代表性方法相比,本文所提方法在归一化均方误差上有2 dB~5 dB的性能提升,在余弦相似度上也有2%~5%的提升,并且在时间复杂度和空间复杂度上均有更好的表现.

Mammalian cloning has been one of the most active research topics in the world. Cioning with in vitro culured foetal fibroblast cells, in comparison with embryonic cells, can be used not only to theoretically study the embryonic or cellular development and differentiation in mammals, but also to utilize the unlimited fibroblast cells to produce large numbers of clonings. The preliminary results are as follows: (i) The division and development of the cloned embryos with embryonic donor cells and goat foetal fibroblast donor cells were 55%, 77% and 35%, 31%, respectively. There is no significant statistical difference between them. (? These studies result in the birth of two cloned goats derived from two 30-day foetal fibroblast celi lines, which are the first cloned mammals from somatic cells in China. This project has established a technological data base for the furture research on adult mammalian somatic cloning and nucleocytoplasmic interactions in animal development, and a novel technique for the

为提高分布式视频编码系统解码WZ(Wyner-Ziv)帧的图像质量,提出了基于广义高斯分布的WZ帧重构算法.该算法充分考虑了边信息与原始WZ帧具有较强相关性的特点,将广义高斯分布作为相关模型;在边信息已知情况下,对给定量化区间、计算WZ帧的条件期望并将其作为WZ重构值;将广义高斯分布的形状参数设为0.5,推导出基于广义高斯分布重构WZ帧的闭式表示.实验结果表明,文中提出的基于广义高斯分布的WZ帧重构算法比最小均方误差(MMSE)重构算法的峰值信噪比提高约0.6 d B,并能有效改善重构WZ帧的图像质量.

Background：Obstructive sleep apnea hypopnea syndrome （OSAHS） constitutes an independent factor for high warfarin dose for patients with pulmonary embolism （PE）.The aim of this study was to investigate whether the 6-month anticoagulation treatment by warfarin is enough for patients with PE complicated by ***：We investigated 97 PE patients,32 of them had OSAHS and 65 *** was administered for 6-month if no abnormal circumstances *** patients were followed up for 18 *** events （AE） included death,major bleeding,hospitalization due to heart failure or pulmonary hypertension,and recurrence or aggravation of PE （including deep vein thrombosis）.Recurrence rate of PE after warfarin cessation was compared between the two ***：OSAHS patients required a significantly higher dose of warfarin than their non-OSAHS counterparts （4.73 mg vs.3.61 mg,P 〈 0.001）.During warfarin treatment,no major bleeding and aggravation of PE occurred among OSAHS patients,and the rates of various AE were not significantly different between the OSAHS and non-OSAHS *** recurrence was higher in OSAHS than non-OSAHS groups after withdrawal of warfarin （21.43% vs.6.78%,P =0.047）.Compared with non-OSAHS patients,OSAHS group had lower international normalized ratio （INR） value but higher plasminogen on baseline and INR resumed to a relatively low level after warfarin ***：OSAHS patients may present with hypercoagulation and relatively high-risk of recurrence of PE after cessation of 6-month warfarin treatment.

花生是我国重要的经济作物之一,约40%的花生用于食用加工。蔗糖含量作为影响花生品质的重要指标,与其风味及口感呈显著正相关。因此,提高花生籽仁中蔗糖含量对花生品质改良具有重要意义。本研究利用NYBP×SYT5-1和19-1934×JHT1两个F2:3群体为试验材料,分析花生籽仁蔗糖含量遗传模型,同时分析了蔗糖含量与含油量、蛋白含量及籽仁相关性状间的相关性。结果表明,花生籽仁蔗糖含量呈连续分布,超亲分离现象明显且具有丰富变异。两群体中蔗糖含量与含油量均呈现显著负相关,与蛋白质含量均显著正相关,蔗糖含量与籽仁长、籽仁宽和百仁重的相关性在两群体间表现不一致。遗传分析结果表明,在两群体中花生籽仁蔗糖含量都表现为主要受两对主基因的加性、显性效应调控,存在明显互作,且主基因间具有累加效应。本研究通过对籽仁蔗糖含量遗传模型分析,初步了解了蔗糖含量的遗传规律,对食用花生品种选育具有指导意义。

协调土地利用和经济发展是一个城市实现可持续发展的关键。基于淮河生态经济带2006~2020年25个地级市面板数据,引入脱钩指数模型,从时间、空间两个维度考察淮河生态经济带城市用地扩张与经济增长间的耦合关系。结果显示:淮河生态经济带城市用地扩张与经济增长的脱钩关系大体上呈现出强脱钩、弱脱钩、增长连结、增长负脱钩4种状态,其中以弱脱钩状态为主;纵向视角,城市经济增长对建设用地的依赖程度相较于前期有所降低,近两年的城市脱钩状态呈现向强脱钩和增长负脱钩两级发展的微弱态势;横向视角,区域发展不平衡,城市间脱钩状态差异显著。基于测算结果,将25个城市归类为脱钩理想型、脱钩一般型和脱钩不理想型三类脱钩城市。在上述分析基础上,认为城市应该坚持推进产业转型升级,合理界定城市边界,加快人口城镇化进程,持续减弱对土地财政的依赖度。
