针对樱桃番茄在实际检测中样品数不足的特点,本研究提出一种深度卷积生成对抗网络(deep convolutional generative adversarial network,DCGAN)模型以同时扩充光谱数据及可溶性固形物含量(soluble solids content,SSC)标签数据,并建立一维卷积神经网络回归(one dimensional-convolutional neural networks regression,1D-CNNR)模型以提高模型的预测精度和泛化能力。为了比较,分别建立偏最小二乘回归(partial least squares regression,PLSR)模型和支持向量机回归(support vector regression,SVR)模型。将原始80个样品数据集、1000个样品的DCGAN扩充数据集和1080个样品的合并数据集,分别结合1D-CNNR、SVR及PLSR进行建模与预测。为了进一步验证模型的泛化能力,一批新的总数为40个样品的樱桃番茄数据作为上述3个模型的新测试集。结果显示,使用合并数据集划分所得校正集进行1D-CNNR建模后,模型为最优的SSC回归检测模型。此时1D-CNNR面向合并样品测试集的预测准确率最高,预测相关系数rp=0.9807,均方根误差RMSE_(p)=0.1929;与SVR与PLSR对比,1D-CNNR面向新的40个样品数据集的预测准确率也最高,其rp=0.9638,RMSE_(p)=0.2245。本研究可为有效准确检测樱桃番茄的可溶性固形物含量提供一种新思路。

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.

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.

Asteroseismology is a unique and powerful tool to investigate the internal structure of stars. CBS 114 is the sixth known pulsating DBV star. It was observed by Handler, Metcalfe, ＆ Wood at the South African Astronomical Observatory over three weeks in 2001. Then, it was observed by Metcalfe et al. for seven nights （2004 Feb. 19-25） on the 1.8 m telescope at the Bohyunsan Optical Astronomy Observatory and seven nights （2004 Feb. 21-27） on the 2.1 m telescope at the McDonald Observatory. Totally two triplets, four doublets, and five singlets were identified. The frequency splitting values are very different, from 5.2 *** to 11.9 ~tHz, which may reflect differential rotations. We evolve grids of white dwarf models by MESA. Cores, added with He/C envelopes, of those white dwarf models are inserted into WDEC to evolve grids of DBV star models. With those DBV star models, we calculate eigenperiods. Those calculated periods are used to fit observed periods. A best-fitting model is selected. The parameters are T^ff ----- 25 000 K, M, = 0.740 MG and log（MHe/M,） = -4.5. With the relatively large stellar mass, the effective temperature is close to the previous spectroscopic result. In addition, kinetic energy distributions are calculated for the best-fitting model. We find that the observed modes with large frequency splitting values are fitted by the calculated modes with a large amount of kinetic energy distributed in the C/O core. After preliminary analysis, we suggest that the C/O core may rotate at least two times faster than the helium layer for CBS 114.
