The underlying physics of QCD phase transition in the early Universe remains largely unknown due to its strong-coupling nature during the quark-gluon plasma/hadron gas transition, yet a holographic model has been proposed to quantitatively fit the lattice QCD data while with its duration of the first-order phase transition(FoPT) left undetermined. At specific baryon chemical potential, the first-order QCD phase transition agrees with the observational constraint of baryon asymmetry. It, therefore, provides a scenario for phase transition gravitational waves(GWs) within the standard model of particle physics. If these background GWs could contribute dominantly to the recently claimed common-spectrum red noise from pulsar timing array(PTA) observations, the duration of this FoPT can be well constrained, and the associated primordial black holes are still allowed by current observations.

Understanding the mechanical properties of the lithologies is crucial to accurately determine the horizontal stress *** investigate the correlation between the rock mass properties and maximum horizontal stress,the three-dimensional(3D)stress tensors at 89 measuring points determined using an improved overcoring technique in nine mines in China were adopted,a newly defined characteristic parameter C_(ERP)was proposed as an indicator for evaluating the structural properties of rock masses,and a fuzzy relation matrix was established using the information distribution *** results indicate that both the vertical stress and horizontal stress exhibit a good linear growth relationship with *** is no remarkable correlation between the elastic modulus,Poisson's ratio and depth,and the distribution of data points is scattered and ***,there is no obvious relationship between the rock quality designation(RQD)and *** maximum horizontal stress σ_(H) is a function of rock properties,showing a certain linear relationship with the C_(ERP)at the same *** addition,the overall change trend of σ_(H) determined by the established fuzzy identification method is to increase with the increase of C_(ERP).The fuzzy identification method also demonstrates a relatively detailed local relationship betweenσ_H and C_(ERP),and the predicted curve rises in a fluctuating way,which is in accord well with the measured stress data.

目的探讨扩散加权成像(DWI)单指数、双指数和扩散峰度模型各定量参数值的直方图分析结果与前列腺癌Gleason评分的相关性,并评价其在鉴别低与中高级别前列腺癌中的诊断效能。方法回顾性分析苏州大学附属第二医院2015年5月至2016年5月间经病理证实为前列腺癌的50例患者资料,男性,60~90岁。所有患者均采用3.0T磁共振设备,行多b值DWI扫描,b值范围0~2000s/mm^2。数据后处理采用全肿瘤直方图分析的方法,在扩散加权成像(DWI)(b=1000s/mm^2)图上沿癌灶轮廓手动逐层勾画感兴趣区,分别采用单指数、双指数及扩散峰度模型进行定量分析,获得前列腺癌区的DWI定量参数值:表观扩散系数(ADC)值、纯水分子扩散系数D值、灌注指数f值、与灌注相关的扩散系数D*值、非高斯分布校正的扩散系数Dk值和峰度系数K值,进一步对各定量参数值做直方图分析,得到其平均数、中位数、25%位数、75%位数、偏度和峰度。运用Spearman秩相关分析各定量参数值的直方图分析结果与前列腺癌Gleason评分的相关性。通过受试者工作特征(ROC)曲线及曲线下面积(AUC)比较各定量参数值的直方图分析结果鉴别低(Gleason评分≤6分)与中高(Gleason评分>6分)级别前列腺癌的诊断效能。结果ADC值、D值和Dk值(平均值、中位数、25%位数、75%位数)均与前列腺癌Gleason评分间具有一定的负相关(r值为-0.388^-0.624,均P0.05)。K值(平均值、中位数、25%位数、峰度)与前列腺癌Gleason评分正相关(r值为0.423~0.699,均P0.05)。结论DWI三种扩散模型定量参数(ADC、D、Dk、K)与前列腺癌的Gleason评分均存在相关性,但在针对低与高级别前列腺癌的鉴别诊断中,单指数模型的诊断效能已足够,较为复杂的双指数模型和扩散峰度模型可能会在其他方面为其提供补充。
