Objective:To test the hypothesis thatβ-glucan enhances protective qi(PQi),an important Chinese medicine(CM)concept which stipulates that a protective force circulates throughout the body surface and works as the first line of defense against"external pernicious influences".Methods:A total of 138 participants with PQi deficiency(PQD)were randomized to receiveβ-glucan(200 mg daily)or placebo for 12 ***’PQi status was assessed every 2 weeks via conventional diagnosis and a standardized protocol from which a PQD severity and risk score was *** of participants’immune and general health status were also monitored,including upper respiratory tract infection(URTI),saliva secretory Ig A(s Ig A),and self-reported measures of physical and mental health(PROMIS).Results:PQi status was not significantly different between theβ-glucan and placebo treatment groups at baseline but improved significantly in theβ-glucan(***)group in a time-dependent *** intergroup differences[95%confidence interval(CI)]in severity score(scale:1-5),risk score(scale:0-1),and proportion of PQD participants(%)at finish line was 0.49(0.35-0.62),0.48(0.35-0.61),and 0.36(0.25-0.47),***,β-glucan improved URTI symptom(scale:1-9)and PROMIS physical(scale:16.2-67.7)and mental(scale:21.2-67.6)scores by a magnitude(95%CI)of 1.0(0.21-1.86),5.7(2.33-9.07),and 3.0(-0.37-6.37),respectively,over ***:β-Glucan ameliorates PQi in PQD *** using stringent evidence-based methodologies,our study demonstrated that Western medicine-derived remedies,such asβ-glucan,can be employed to advance CM therapeutics.(Clinical *** registry:NCT03782974)

Quantum public-key crypto via EPR pairs

引用

Science China(Physics,Mechanics & Astronomy) 2025年第1期Mechanics & Astronomy) .卷 58-63页

作者： Xiang-Qun Fu Hong-Wei Li jian-Hong shi Tan Li Wan-Su Bao Henan Key Laboratory of Quantum Information and Cryptography Information Engineering University Synergetic Innovation Center of Quantum Information and Quantum Physics University of Science and Technology of China

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.

通过对《型世言》、《儿女英雄传》中的方位词"上下"计量对比研究,发现:从数量分布上看,《儿女英雄传》占据了绝对的优势,非常接近其在现代汉语中的分布。从功用的角度来看,尽管从明代末期到清代中期,仅仅只有二百多年的时间,但"上下"在两书中有着不小的差别:在《型世言》中,"上下"作为方位词,其各种用法刚刚萌芽,基本上只能单用,作主语、宾语、状语;而"上下"在《儿女英雄传》中,除了单用,还可以与其他词联合成短语,作主语、宾语、状语和定语,与现代汉语中的用法基本相仿。

In this paper,we study the dynamics of k-essence in loop quantum cosmology(LQC).The study indicates that the loop quantum gravity(LQG)effect plays a key role only in the early epoch of the universe and is diluted in the later *** fixed points in LQC are basically consistent with those in standard Friedmann-Robertson-Walker(FRW)*** most of the attractor solutions,the stability conditions in L Q C are in agreement with those for the standard FRW *** some special fixed points,however,tighter constraints are imposed thanks to the LQG effect.

Dear Editor, Phenotypic drug discovery, which observes compound effects on physiology,has given way to targeting specific molecules, but has revived by using modern methods to find drugs based on therapeutic outcomes in disease models(Vincent et al., 2022). Osteoarthritis(OA) is a prevalent chronic joint disorder, primarily affecting knee joints, with osteoclast activation due to low-grade inflammation resulting in increased bone resorption and structural changes in the joint(Katz et al.,2021).

限制极性分子的运动是降低聚合物介电损耗的有效手段.合成了含杂萘联苯结构的聚芳醚,随后进行热压处理以降低其自由体积,限制分子链段运动,从而降低材料的介电损耗.实验结果表明,系列聚芳醚薄膜在热压处理后的介电损耗明显降低,降低率最大为10.27%;材料自由体积的降低也使其玻璃化转变温度提高,提高率最大为13.0%.采用XRD测试并计算材料的分子链间距以反映材料自由体积的变化,应用Materials Studio软件模拟聚芳醚于热压前后的自由体积分数的变化,二者均与材料的介电损耗、玻璃化转变温度变化规律相符,证明通过热压处理降低材料自由体积以提升其性能是一种可行手段.

Quantum-chemical Study on the Structures and Properties of Uracil-BX_3 (X = F,Cl) Complexes

引用

Chinese Journal of Structural Chemistry 2006年第8期25卷 947-956页

作者： ZHANG shi-Guo LI Hong YANG pin Department of Chemistry and Chemical Engineering Institute ofMaterial Chemistry Binzhou University Binzhou 256603 China Key Laboratory. of Chemical Biology and Molecular Engineering of Minist~ ofEducation Institute of Molecular Science Shanxi University Taiyuan 030006 China

For the uracil-BX3 （X = F, Cl） systems, geometries and binding energies have been calculated by using the Lee-Young-Parr correlation functionals （B3LYP） method of density functional theory （DFT） and the second-order Moller-Plesset （MP2） method of ab initio at the 6- 311 ＋G^＊ or 6-311 ＋＋G^＊ basis set. Four isomers were found for each system, and then the single-point energy evaluations were performed using the larger basis sets of （6-311 ＋G（2df, p） and aug-cc-pVDZ with DFF method. In the most stable isomer of uracil-BF3 or uracil-BCl3, the boron atom of BX3 （X = F, Cl） connects to the carbonyl oxygen O7 of uracil with a stabilization energy of -46.56 or -31.10 kJ/mol at the B3LYP/6-31 1＋G^＊ level （BSSE corrected）. The analyses for combining interaction between BX3 and uracil with the atom-in-molecule theory （AIM） and natural bond orbital method （NBO） have been performed. The results indicate that all isomers were formed with σ-p type interactions between uracil and BX3, in which the carbonyl oxygen offers its lone pair electrons to the empty p orbital of boron atom and the concomitances of charge transfer from uracil to BX3 occur. Moreover, there exists one or two hydrogen bonds in most isomers of uracil-BX3 system and these hydrogen bonds contribute to the stability of the complex systems. Frequency analysis suggests that the stretching vibration of BX3 undergoes a red shift in complexes. Uracil-BF3 complex is more stable than uracil-BCl3 although the distance of B-O is shorter in the latter. Besides, the conversion mechanisms between different isomers of uracil-BF3 have been obtained.
