There has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics. This renaissance has been driven in part by the discovery of a plethora of charmonium-like XyZ states at BESⅢ and B factories, and the observation of an intriguing proton-antiproton threshold enhancement and the possibly related X(1835) meson state at BESⅢ, as well as the threshold measurements of charm mesons and charm baryons. We present a detailed survey of the important topics in tau-charm physics and hadron physics that can be further explored at BESⅢ during the remaining operation period of BEPCⅡ. This survey will help in the optimization of the data-taking plan over the coming years, and provides physics motivation for the possible upgrade of BEPCⅡ to higher luminosity.

Spinal muscular atrophy(SMA)is a genetic condition that results in selective lower motor neuron loss with concomitant muscle weakness and *** genetic cause of SMA was understood in 1995 when loss or impairment of the survival motor neuron 1(SMN1)gene was identified as the main contributing factor(Lefebvre et al.,1995).This,in combination with the discovery that humans have a“back-up”gene,SMN2,which can produce low levels(approximately 10%)of the full-length functional SMN protein,has led to the generation of SMA-specific gene *** was traditionally classified according to age of symptom onset and developmental milestones achieved,with life expectancy and severity varying between ***,SMN2 copy number is used as a proxy for the prediction of disease severity,with higher SMN2 copy number typically being associated with reduced severity of SMA,although this relationship is not absolute:some individuals with low SMN2 copy number have less severe SMA phenotypes and vice ***,the etiology of SMA is further complicated by other factors,such as non-typical nucleotide variants and SMN2-independent modifiers of disease severity.

Studies of e^+e~→D_s^+■^((*)0)K^-and the P-wave charmed-strange mesons are performed based on an e^+e^-collision data sample corresponding to an integrated luminosity of 567 pb^(-1) collected with the BESIII detector at s^(1/2)=4.600 GeV. The processes of e^+e^-→D_s^+■^(*0)K^- and D_s^+■~0K^- are observed for the first time and are found to be dominated by the modes D_s^+D_(s1)(2536)^-and D_s^+D_(s2)~*(2573)^-, respectively. The Born cross sections are measured to be σ~B(e^+e^-→D_s^+■^(*0)K^-) =(10.1±2.3±0.8) pb and σ~B(e^+e^-→D_s^+■~0K^-) =(19.4±2.3± 1.6) pb, and the products of Born cross section and the decay branching fraction are measured to be σ~B(e^+e^-→D_s^+D_(s1)(2536)^-+c.c.)·B(D_(s1)(2536)^-→■^(*0)K^-)=(7.5±1.8±0.7) pb and σ~B(e^+e^-→D_s^+D_(s2)~*(2573)^-+ c.c.)·B(D_(s2)~*(2573)^-→■~0 K^-)=(19.7 ± 2.9 ±2.0) pb. For the D_(s1)(2536)^-and D_(s2)~*(2573)^-mesons, the masses and widths are measured to be M(D_(s1)(2536)^-)=(2537.7±0.5 ±3.1) MeV/c2, Γ(D_(s1)(2536)^-) =(1.7 ±1.2 ±0.6)MeV, and M(D_(s2)~*(2573)^-)=(2570.7±2.0 ±1.7) MeV/c^2, Γ(D_(s2)~*(2573)^-)=(17.2 ±3.6 ±1.1) MeV. The spin-parity of the D_(s2)~*(2573)^-meson is determined to be j^p= 2^+. In addition, the processes e^+e^-→D_s^+■^((*)0)K^-are searched for using the data samples taken at four(two) center-of-mass energies between 4.416(4.527) and 4.575 GeV, and upper limits at the 90% confidence level on the cross sections are determined.

Study on the Radiation Synthesis Mechanism and the Electrochemical Property of Polyaniline

CHINESE jOURNAL OF POLyMER SCIENCE 2025年第2期43卷 328-340页

As a highly promising conductive polymer material, the synthesis method, structure regulation, and performance improvement of polyaniline (PANI) are hot research topics. In this work, the radiation-induced polymerization of aniline in HNO3 solution was successfully achieved at room temperature without the use of chemical oxidants. Through the analysis of the radiation chemical reactions of inorganic acids and nitrate salt solutions, the characterization of the intermediate free radicals in the irradiated systems, and the influence of the pH of the solutions on the polymerization activity and product morphologies, the radiation-induced polymerization mechanism of aniline is discussed in detail and proposed. Only at a condition of [HNO3]>[aniline], i.e., pHy obtained under gamma-ray radiation. The polymerization begins with the oxidation of aniline cations to aniline cation radicals by NO3 generated by radiolysis reactions, and undergoes repeated three steps of monomer free radical recombination, deprotonation, and oxidation reaction of NO3, thus forming a PANI macromolecule. In addition to the polymerization reaction, the aniline units are protonated and oxidized because of the strongly acidity and oxidation of the reaction system under gamma-ray irradiation, which means that the molecular chain structure of the radiation-synthesized PANI can be regulated by pH, nitrate concentration, and irradiation conditions. Radiation-synthesized PANI has a moderate protonation and oxidation state, which can be used for the preparation of PANI supercapacitors with better electrochemical properties than those prepared by chemical oxidation under the same conditions. This work presents a new radiation-synthesis method and polymerization mechanism of PANI, which not only expands the application of radiation technique in the field of polymer synthesis, but also provides a new idea for the structural regulation and electrochemical p

全过程人民民主是人民民主在实践中的最新形态,是人民民主本身人民性的价值要求。全过程人民民主以人民代表大会制度作为制度载体,但不限于人民代表大会制度的丰富和完善。在发展全过程人民民主过程中,关键是要健全人民当家作主的制度体系,充分调动人民民主的主体人民参政议政的主动性和积极性。全过程人民民主制度化表现为对“法治人大”价值理念的追求,同时还需要进一步加强协商民主制度建设,强化基层自治,进一步扩大统一战线,要以充分发挥人大代表的作用为抓手,全面和系统地保障全过程人民民主有效实现,进而推进中国式现代化的顺利进行。
