The global spin alignment of vector mesons has been observed by the STAR collaboration at the Relativistic Heavy Ion Collider （RHIC） at Brookhaven National Laboratory （BNL）.It provides a unique opportunity to probe the correlation between the polarized quark and antiquark in the strongly coupled quark-gluon plasma （sQGP） produced in relativistic heavy ion collisions,opening a new window to explore the properties of s *** addition,spin alignments of vector mesons have also been observed in other high-energy particle collisions such as e+e-annihilations at high energies where hadron production is dominated by quark fragmentation *** results obtained are quite different from those obtained in heavy ion collisions where quark coalescence/combination mechanism dominates suggesting strong dependence on hadronization *** comprehensive studies in different hadronization processes are *** this article,we present a brief review of theoretical and experimental advances in the study of vector meson’s spin alignments in a variety of high-energy particle collisions,with emphasis on hadronization mechanisms.

Fluorescent vesicles have recently attracted increasing attention because of their potential applications in bioimaging,diagnostics, and theranostics, for example, in vivo study of the delivery and the distribution of active substances. However, fluorescent vesicles containing conventional organic dyes often suffer from the problem of aggregation-caused quenching(ACQ) of *** vesicles working with aggregation-induced emission(AIE) offer an extraordinary tool to tackle the ACQ issue, showing advantages such as high emission efficiency, superior photophysical stability, low background interference, and high sensitivity. AIE fluorescent vesicles represent a new type of fluorescent and functional nanomaterials. In this review, we summarize the recent advances in the development of AIE fluorescent vesicles. The review is organized according to the chemical structures and architectures of the amphiphilic molecules that constitute the AIE vesicles, i.e., small-molecule amphiphiles, amphiphilic polymers, and amphiphilic supramolecules and supramacromolecules. The studies on the applications of these AIE vesicles as stimuli-responsive vesicles,fluorescence-guided drug release carriers, cell imaging tools, and fluorescent materials based on fluorescence resonance energy transfer(FRET) are also discussed.

This article reviews the available published data on optimizing clopidogrel and aspirin therapy using translational and integrative medicine. Translational and evidence-based medical studies show that the CYP2 C19 gene mutation(CYP2 C19*2 and CYP2 C19*3) could affect > 50% of the Chinese population, and that this mutation is closely associated with clopidogrel resistance and an increased risk of major adverse cardiovascular events, particularly stent thrombosis in patients following percutaneous coronary intervention(PCI). Adjusted-dose warfarin and aspirin reduce stroke in patients with atrial fibrillation(AF), and warfarin is substantially more efficacious than aspirin. However, a poor compliance is a big problem in warfarin use especially in China. The genetic variants of vitamin K expoxide reductase might account for the universally lower warfarin dosage used in Chinese population. The available evidence indicates that the integrating mainstream treatments(e.g., clopidogrel, CYP2 C19 genotyping) and non-mainstream medicines [e.g., Chinese medicines,Naoxintong Capsule(脑心通胶囊, NXT)] to treat CYP2 C19 gene mutation patients following PCI can be *** combined NXT and the adjusted-dose warfarin was equally effective in elderly patients with non-valvular AF in prevention of ischemic stroke.

针对现有无人机遥感图像分割算法普遍存在的未充分利用位置信息、小目标分割不准确等问题，基于DeeplabV3+网络提出融合注意力机制和多尺度特征的无人机遥感图像语义分割方法。首先，在DeeplabV3+网络基础上，用经过预训练的MobileNetV2网络替代原模型中的Xception主干网络，减少模型参数量；其次，在空洞空间金字塔池化结构中加入坐标注意力细化模块以充分利用位置信息来增强深层特征，并通过多尺度特征融合模块处理骨干网络不同层次的信息，帮助模型更好地适应不同尺度的物体；最后，利用双三次插值上采样法替代双线性插值上采样法，便于模型对特征图进行上采样，在训练时用Dice损失和交叉熵损失之和作为模型的损失函数来预防无人机图像存在的类别不平衡问题。实验结果表明：改进后模型在Aeroscapes数据集上的平均交并比、类别平均像素准确率分别为67.23%、76.01%,与原模型相比分别提高了6.89%、6.59%;在WHDLD数据集上的平均交并比、类别平均像素准确率分别为66.09%、78.19%,与原模型相比分别提高了0.88%、2.04%。

The convergence of an adaptive model predictive control(MPC) algorithm for discrete-time linear stochastic systems with unknown parameters is investigated in this paper. The proposed adaptive MPC is designed by solving a finite horizon constrained linear-quadratic optimal control problem of online estimated models, which are built on a recursive weighted least-squares(WLS) algorithm together with a random regularization method. By incorporating an attenuating excitation signal into adaptive MPC, the proposed adaptive MPC is shown to converge asymptotically to the ergodic MPC performance with known parameters by using the Markov chain ergodic theory.

We study the production and angular correlationof charm hadrons in hot and dense matter produced in high-energy nuclear-nuclear collisions within a multiphasetransport model(AMPT).By triggering additional charm-anticharm quark pair production in the AMPT,the modeldescribes the D^0 nuclear modification factor in the low andintermediate pr regions in Au+Au collisions at√VSNN=200 GeV reasonably *** exploration of the D^0 pair azimuthal angular correlation for different centralitiesshows clear evolution from low-multiplicity to high-mul-tiplicity events,which is associated with the number ofcharm quark interactions with medium partons duringAMPT transport.

By implementing an additional heavy quark-antiquark pair production trigger in a multiphase transport(AMPT)model,we study the effect on anisotropy flows of identified particles with a focus on charged particles and quarkonium(J/ΨandΥ).A systematic increase in the collision rate for active partons in the AMPT model with such an implementation has been *** leads to a slight increase of identified particles anisotropy flows as a function of transverse momentum(pT)and rapidity,and gives a better description of the experimental data of elliptic flow toward larger *** approach provides an efficient way to study the heavy quark dynamics in the AMPT model at LHC energies.
