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.

Recently, compressive tracking （CT） has been widely proposed for its efficiency, accuracy and robustness on many challenging sequences. Its appearance model employs non-adaptive random projections that preserve the structure of the image feature space. A very sparse measurement matrix is used to extract features by multiplying it with the feature vector of the image patch. An adaptive Bayes classifier is trained using both positive samples and negative samples to separate the target from background. On the CT frame- work, however, some features used for classification have weak discriminative abilities, which reduces the accuracy of the strong classifier. In this paper, we present an online compressive feature selection algorithm（CFS） based on the CT framework. It selects the features which have the largest margin when using them to classify positive samples and negative samples. For features that are not selected, we define a random learning rate to update them slowly, It makes those weak classifiers preserve more target information, which relieves the drift when the appearance of the target changes heavily. Therefore, the classifier trained with those discriminative features couples its score in many challenging sequences, which leads to a more robust tracker. Numerous experiments show that our tracker could achieve superior result beyond many state-of-the-art trackers.

目的探讨不同剂量阿替普酶联合瑞舒伐他汀治疗急性缺血性脑卒中的疗效及安全性。方法收取2010年1月至2015年12月于西电集团医院就诊的急性缺血性脑卒中患者82例作为研究对象,采用随机数字表法将其分为观察组与对照组各41例,观察组给予标准剂量阿替普酶(0.9 mg/kg)联合瑞舒伐他汀治疗,对照组给予低剂量阿替普酶(0.6 mg/kg)联合瑞舒伐他汀治疗。对两组患者治疗前后神经系统功能损伤、血脂变化情况、临床疗效、患者恢复情况及不良反应进行考察。结果治疗后两组患者NIHSS评分及CSS评分均有所下降,与治疗前相比差异有统计学意义(P<0.05)。同时间点两组间差异不显著;治疗后两组患者总胆固醇(TC)及低密度脂蛋白(LDL)明显下降,差异较治疗前有统计学意义(P<0.05),观察组明显低于对照组,差异有统计学意义(P<0.05)。观察组总有效率与对照组比较差异无显著性。治疗后两组MRS评分均较治疗前下降,且随时间逐渐降低,差异有统计学意义(P<0.05)。观察组治疗后MRS评分低于对照组,自治疗后14d开始有统计学差异(P<0.05)。两组不良反应发生率比较差异无显著性。结论标准剂量阿替普酶联合瑞舒伐他汀与小剂量阿替普酶相比疗效及安全性相当,但对于改善患者血脂水平及恢复情况更具优势,因此值得临床推广应用。
