Multi-lateral multi-issue negotiations are the most complex realistic negotiation problems. Automated ap- proaches have proven particularly promising for complex ne- gotiations and previous research indicates evolutionary com- putation could be useful for such complex systems. To im- prove the efficiency of realistic multi-lateral multi-issue ne- gotiations and avoid the requirement of complete informa- tion about negotiators, a novel negotiation model based on art improved evolutionary algorithm p-ADE is proposed. The new model includes a new multi-agent negotiation protocol and strategy which utilize p-ADE to improve the negotia- tion efficiency by generating more acceptable solutions with stronger suitability for all the participants. Where p-ADE is improved based on the well-known differential evolution （DE）, in which a new classification-based mutation strategy DE/rand-to-best/pbest as well as a dynamic self-adaptive pa- rameter setting strategy are proposed. Experimental results confirm the superiority of p-ADE over several state-of-the-art evolutionary optimizers. In addition, the p-ADE based multi- agent negotiation model shows good performance in solving realistic multi-lateral multi-issue negotiations.

本文采用密度泛函(DFT)方法研究了定向外电场(OEEF)对W_(6)C_(6)团簇几何结构、电子性质以及非线性光学响应(NLO)的影响.计算结果表明W_(6)C_(6)的结构在一定OEEF强度下可以保持稳定.OEEF可以增大W_(6)C_(6)团簇的电子亲和能(EA值),且在特定强度下,OEEF可以将W_(6)C_(6)团簇转变为超卤素.通过对EA值的非线性拟合可以实现对W_(6)C_(6)团簇的连续调制.进一步对不同外电场下W_(6)C_(6)团簇的最高占据分子轨道(HOMO)和最低未占据分子轨道(LUMO)能级进行分析,发现OEEF降低了W_(6)C_(6)团簇LUMO能级是其EA值增大的主因.此外,OEEF可以显著增大W_(6)C_(6)团簇的平均极化率和第一超极化率,尤其是第一超极化率,改变其非线性光学性质.

目的分析计算机断层扫描灌注成像(CTR)参数联合血同型半胱氨酸(Hcy)、超敏C反应蛋白(hs-CRP)检测预测短暂性脑缺血发作(TIA)进展为急性脑梗死(ACI)的价值。方法将2021年4月至2023年4月在我院收治的85例TIA患者纳入为此次研究对象,所有入组患者均于入院24h内完成CTP检查,并检测血H cy、hs-C RP水平,根据患者发病后7d内是否进展为ACI将入组对象分组为ACI组、非ACI组。比较ACI组、非ACI组一般资料、CTP参数[脑血容量(CBV)、脑血流量(CBF)、平均通过时间(MTT)、达峰时间(TTP)]、血Hcy、hs-CRP水平,绘制ROC分析上述指标检测对TIA进展为ACI的预测效能。结果85例TIA患者7d内16例进展为ACI,ACI发生率为18.82%(16/85)。ACI组合并高血压、合并高脂血症比例明显高于非ACI组(P0.70,预测效能较好,且以联合最佳。根据ROC曲线得出CTP参数(CBV、CBF、MTT、TTP)、血Hcy、hs-CRP的cut-off值分别为2.97mL/100 g、34.19 mL/min·100 g、8.75 s、12.65s、16.14μmol/L和5.27 mg/L。结论 CTP参数联合血Hcy、hs-CRP检测对预测TIA进展为ACI有一定的应用价值,且以联合效果更佳。

On July 27, 2022, a high-precision system for measuring the magnetic field based on a coherent population trapping magnetometer（referred to as the CPT system） was launched onboard the Space Advanced Technology demonstration satellite（SATech-01） by a ZK-1A rocket. The payload comprises a scalar coherent population trapping magnetometer（CPTM）, triaxial anisotropic magnetoresistance magnetometer（AMRM）, and nano star tracker mounted on a non-magnetic telescopic tubular mast. This configuration enables synchronized measurement of scalar and vector geomagnetic fields, as well as the attitude,making the payload with its compact sensors suitable for applications on miniature satellite platforms. On November 7, 2022,the novel telescopic tubular mast was deployed in orbit, extending to a length of 5.28 m. The CPTM, an absolute scalar magnetometer with an omnidirectional sensor, is the first China-developed quantum/atomic magnetometer successfully operating in space. In orbit, the CPTM has sensitivity of ～10 pT/Hz1/2and can automatically operate under complex magnetic field variations. The difference between the scalar fields obtained using the CPTM and CHAOS model has a mean deviation of–3.73 n T and a standard deviation of 26.11 nT（1σ）, without on-orbit calibration or correction. The miniaturized AMRM has a sensitivity of ～0.3 n T/Hz1/2and maintains stable and reliable operation in orbit. The low-power and miniaturized nano star tracker has a measurement uncertainty of 14.23″（1σ） in orbit. The mission has realized the on-orbit technical verification of the integrated and synchronized detection of the vector magnetic field and attitude and fully validated the system's performance,automation level, and reliability.

We proposed a fast and temperature self-compensation method to detect streptomycin sulfate aqueous solution concentration based on a 2D Nb2CTXMXene nanosheets functionalized tilted Bragg grating（N-TFBG）. The introduction of 2D Nb2CTXMXene nanosheets brought more than 100% increase in sensitivity and exhibited a high sensitivity of 253.8 pm/mg/mL and detection limit 80 μg/mL in range of 0.2-0.8 mg/mL. Due to high sensitivity and compact structure， N-TFBG sensor has a faster measure time than previous method; additionally， the sensor has simultaneous temperature measurement by detecting the cladding mode and the core mode resonance peak simultaneously. Our research will hopefully open a new research platform for online detection of streptomycin sulfate concentration.
