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.

To analyze the correlation between the systemic inflammation score (SIG) and plaque stability in patients with carotid artery stenosis, and to evaluate the predictive value. The clinical data of 149 patients with carotid artery stenosis who were hospitalized in Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from January 2019 to October 2023 were retrospectively analyzed, including 124 males and 25 females, aged (68.2±8.9) years. According to the results of pathological analysis of specimens after carotid endarterectomy, the patients were divided into plaque stable group (=70) and plaque vulnerable group (=79). After preoperative blood biochemical indexes were collected and neutrophil-lymphocyte ratio and modified glasgow prognostic score(mGPS) were calculated, the SIG was calculated together. The multivariate logistic regression model was used to analyze the correlative factors of plaque stability in patients with carotid artery stenosis, and the receiver operating characteristic (ROC) curve was used to analyze the predictive value of SIG for plaque stability in patients with carotid artery stenosis. The proportion of patients with a history of diabetes in the plaque vulnerable group [36.7% (29/79) vs 20.0% (14/70)] and Il-6 [0.43 (0.31, 0.64) vs 0.34 (0.17, 0.44) ng/l] were higher than those in the plaque stabilization group(both laque vulnerable group were higher than those of the plaque stabilization group (both lts of the multivariate logistic regression model showed that diabetes history (=2.82, 95%: 1.23-6.48), high interleukin-6 (Il-6) level (=1.16, 95%: 1.01-1.33), and high SIG scores [with SIG=0 as the reference, (SIG=1)=1.76,95%:1.21-2.41; (SIG=2)=2.21,95%:1.51-3.01; (SIG=3)=4.47,95%:2.42-6.52; (SIG=4)=3.19,95%:2.01-4.36] were risk factors for plaque instability in patients with carotid artery stenosis.

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.

Traditional research on skin diseases has mainly focused on biological characteristics for a long time. Recently, the integration of biomechanics and mechanobiology has introduced mechanical factors into skin disease research. The interaction between mechanical factors and skin's physiological and pathological changes has gradually been transformed in clinical diagnosis and treatment. The two emerging fields, mechanodiagnostics and mechanotherapy, have been developed to address clinical needs. However, clinicians often lack a comprehensive understanding of skin mechanical characteristics and the mechanobiological mechanisms in dermatology. Thus, we propose the concept of "skin mechanomedicine". By summarizing relevant research at home and abroad, this paper systematically elucidates the multiscale mechanical characteristics of skin diseases and their impact on biological behavior from four perspectives: skin biomechanics, skin mechanobiology, skin mechanodiagnostics, and skin mechanotherapy. Meanwhile, in-depth exploration was conducted on the potential application of mechanical factors in the diagnosis and treatment of skin diseases, aiming to provide new research perspectives and solutions for the diagnosis and treatment of skin diseases.

为实现城市污水处理厂非二氧化碳温室气体减排与控制,对北京市某大型城市污水处理厂厌氧-缺氧-好氧(A^(2)O)工艺进行了为期1 a的氧化亚氮(N_(2)O)长期监测.结果表明,城市污水处理厂A^(2)O工艺厌氧区和缺氧区能够有效去除回流污泥中含有的溶解态N_(2)O,而好氧区是N_(2)O产生和排放的主要区域,其产生途径可能以氨氧化菌(AOB)反硝化为主.城市污水处理厂冬季和夏季N_(2)O产生有显著差距,其N_(2)O释放通量平均值相差可达7.6倍,冬季N_(2)O排放量平均值为32.75 kg·月^(-1),明显高于夏季的6.06kg·月^(-1).研究发现亚硝酸盐氮(NO_(2)^(-)-N)积累和溶解氧(DO)浓度对N_(2)O产生均有显著影响,因而为实现A^(2)O工艺N_(2)O减排,好氧区在冬季和夏季ρ(NO_(2)^(-)-N)应分别控制在0.40 mg·l^(-1)和0.10 mg·l^(-1)以下;而ρ(DO)应维持在1.2 mg·l^(-1)以上.

Currently,the Al_(2)O_(3)content in the high-alumina slag systems within blast furnaces is generally limited to 16wt%–18.5wt%,making it challenging to overcome this *** most studies that concentrated on managing the MgO/Al_(2)O_(3)ratio or basicity,this paper explored the effect of equimolar substitution of MgO for CaO on the viscosity and structure of a high-alumina CaO-MgO-Al_(2)O_(3)-SiO_(2)slag system,providing theoretical guidance and data to facilitate the application of high-alumina *** results revealed that the viscosity first decreased and then increased with higher MgO substitution,reaching a minimum at 15mol%MgO *** transform infrared spectroscopy(FTIR)results found that the depths of the troughs representing[SiO_(4)]tetrahedra,[AlO_(4)]tetrahedra,and Si-O-Al bending became progressively deeper with increased MgO *** of the Raman spectra showed that the average number of bridging oxygens per Si atom and the X_(q^(3))/X_(q^(2))(X_(q^(i))is the molar fraction of q^(i) unit,and i is the number of bridging oxygens in a[SiO_(4)]tetrahedral unit)ratio increased from 2.30 and 1.02 to 2.52 and 2.14,respectively,indicating a progressive polymerization of the silicate structure.X-ray photoelectron spectroscopy(XPS)results highlighted that non-bridging oxygen content decreased from 77.97mol% to 63.41mol% with increasing MgO concentration,whereas bridging oxygen and free oxygen contents *** analysis demonstrated a gradual increase in the polymerization degree of the tetrahedral structure with the increase in MgO ***,bond strength is another important factor affecting the slag *** occurrence of a viscosity minimum can be attributed to the complex evolution of bond strengths of non-bridging oxygens generated during depolymerization of the[SiO_(4)]and[AlO_(4)]tetrahedral structures by CaO and MgO.
