With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.

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.

Stokes drift is the main source of vertical vorticity in the ocean mixed layer. In the ways of Coriolis - Stokes forcing and Langmuir circulations, Stokes drift can substantially affect the whole mixed layer. A modified Mellor-Yamada 2. 5 level turbulence closure model is used to parameterize its effect on upper ocean mixing conventionally. Results show that comparing surface heating with wave breaking, Stokes drift plays the most important role in the entire ocean mixed layer, especially in the subsurface layer. As expected, Stokes drift elevates both the dissipation rate and the turbulence energy in the upper ocean mixing. Also, ilffluence of the surface heating, wave breaking and wind speed on Stokes drift is investigated respectively. Research shows that it is significant and important to assessing the Stokes drift into ocean mixed layer studying. The laboratory observations are supporting numerical experiments quantitatively.

目的:分析2011—2020年广州市肺结核患者的死亡情况和死亡率变化趋势,为制定防控策略和措施提供科学依据。方法:采用Joinpoint回归模型分析2011—2020年广州市全年龄段人群肺结核死亡率变化趋势,并计算年度变化百分比(annual percent change,APC)和平均年度变化百分比(average annual percent change,AAPC);使用年龄-时期-队列模型分析广州市20~85岁人群肺结核死亡风险的年龄、时期和队列效应。结果:广州市2011—2020年报告肺结核死亡患者2144例,年均报告标化死亡率为2.57/10万;男性肺结核标化死亡率为4.19/10万,约为女性标化死亡率(0.96/10万)的4.4倍。10年间广州市肺结核年龄标化死亡率总体呈现下降趋势,AAPC为-4.15%(95%CI:-6.41%~-1.85%,P=0.003);其中,女性肺结核死亡率下降速度高于男性,AAPC分别为-6.72%(95%CI:-10.38%~-2.92%,P=0.004)和-3.55%(95%CI:-6.19%~-0.85%,P=0.017)。在不同年龄段人群中,0~49岁和≥65岁年龄段人群肺结核死亡率均呈现明显下降趋势,AAPC分别为-7.05%(95%CI:-11.52%~-2.34%,P=0.009)和-3.94%(95%CI:-6.22%~-1.62%,P=0.005)。年龄-时期-队列模型的年龄效应显示,随着年龄的增长,肺结核死亡风险不断上升,≥65岁人群尤为显著,发病率由66~67岁年龄组的2.93/10万增长至84~85岁年龄组的6.10/10万。时期效应显示,肺结核死亡风险随着时期的变化总体呈现下降趋势,相对危险度(risk ratio,RR)从2011—2012年时期组的1.35下降至2019—2020年时期组的0.81。队列效应显示,越晚出生的人群肺结核死亡风险越低,RR值从1926—1927年出生队列的5.91降低至1998—1999年出生队列的0.16。结论:广州市肺结核死亡率总体呈不断下降的趋势,但男性和女性肺结核死亡率差距较大。需重点关注男性和≥65岁年龄段的老年人群,并实施针对性的防控和治疗措施。

The normalization of quantitative real-time PCR （qPCR） is important to obtain accurate gene expression data, and the most common method for qPCR normalization is to use reference genes. However, reference genes can be regulated under different conditions, qPCR has recently been used for gene expression study in Laodelphax striatellus, but there is no study on validation of the reference genes. In this study, five new housekeeping genes （LstrTUB1, LstrTUB2, LstrTUB3, LstrARF and LstrRPL9） in L. striatellus were cloned and deposited in the GenBank with accession numbers of JF728809, JF728810, JF728811, JF728807 and JF728806, respectively. Furthermore, mRNA expressions of the five genes and β-actin were measured by qPCR with insect samples of different instar at nymph stage, and the expression stabilities were determined by the software geNorm and NormFinder. As a result, ARF and RPL9 were consistently more stable than β-actin, while three TUB genes were less stable than β-actin. To determine the optimal number of reference genes used in qPCR, a pairwise variations analysis by geNorm indicated that two references ARF and RPL9 were required to obtain the accurate quantification. These results were fiarther confirmed by the validation qPCR experiment with chitinase gene as the target gene, in which the standard error of the mRNA quantification by using binary reference ARF-RPL9 was much lower than those by ARF, RPL9 or β-actin alone. Taken together, our study suggested that the combination of ARF-RPL9 could replace β-actin as the reference genes for qPCR in L. striatellus.
