We introduced the work on parallel problem solvers from physics and biology being developed by the research team at the state key laboratory of software Engineering, {4.. Results on parallel solvers include the following areas: Evolutionary algorithms based on imitating the evolution processes of nature for parallel problem solving, especially for parallel optimization and model-building; Asynchronous parallel algorithms based on domain decomposition which are inspired by physical analogies such as elastic relaxation process and annealing process, for scientific computations, especially for solving nonlinear mathematical physics problems. All these algorithms have the following common characteristics: inherent parallelism, self-adaptation and self-organization, because the basic ideas of these solvers are from imitating the natural evolutionary processes.

Multi-objective optimization is a new focus of evolutionary computation research. This paper puts forward a new algorithm, which can not only converge quickly, but also keep diversity among population efficiently, in order to find the Pareto-optimal set. This new algorithm replaces the worst individual with a newly-created one by 'multi-parent crossover' , so that the population could converge near the true Pareto-optimal solutions in the end. At the same time, this new algorithm adopts niching and fitness-sharing techniques to keep the population in a good distribution. Numerical experiments show that the algorithm is rather effective in solving some Benchmarks. No matter whether the Pareto front of problems is convex or non-convex, continuous or discontinuous, and the problems are with constraints or not, the program turns out to do well.

本文给出了一种新的求解多峰函数优化问题的定义:定位所有的极值点,包括全局的峰值点和局部的峰值点。传统的演化算法框架都是群体固定的演化迭代过程,对求解多峰函数优化问题时由于无法事先得知峰值点的个数而很难确定合适的群体大小,影响了算法的效率。提出一种群体动态可调的演化方式,使得初始群体大小可任意指定,在演化过程中通过聚集和按比例引入新个体两个过程而动态变化。实验表明,该算法能尽可能多地定位峰值点。

We introduce a new parallel evolutionary algorithm in modeling dynamic systems by nonlinear higher-order ordinary differential equations (NHODEs). The NHODEs models are much more universal than the traditional linear models. In order to accelerate the modeling process, we propose and realize a parallel evolutionary algorithm using distributed CORBA object on the heterogeneous networking. Some numerical experiments show that the new algorithm is feasible and efficient.

The floating offshore wind turbine(FOWT) is widely used for harvesting marine wind energy. Its dynamic responses under offshore wind and wave environment provide essential reference for the design and installation. In this study,the dynamic responses of a 6 MW Spar type FOWT designed for the water depth of 100 m are investigated by means of the wave tank experiment and numerical analysis. A scaled model is manufactured for the experiment at a ratio of65.3, while the numerical model is constructed on the open-source platform FAST(Fatigue, Aerodynamics,Structures, and Turbulence). Still water tests, wind-induced only tests, wave-induced only tests and combined windwave-current tests are all conducted experimentally and numerically. The accuracy of the experimental set-up as well as the loading generation has been verified. Surge, pitch and heave motions are selected to analyze and the numerical results agree well with the experimental values. Even though results obtained by using the FOWT calculation model established in FAST software show some deviations from the test results, the trends are always consistent. Both experimental and numerical studies demonstrate that they are reliable for the designed 6 MW Spar type FOWT.

目的通过监测全国血流感染革兰阳性菌病原谱分布及其耐药趋势,为临床革兰阳性菌血流感染提供更为合理的防控方案。方法收集全国血流感染细菌耐药监测联盟(BRICS)成员单位2022年1至12月所有分离自血培养的革兰阳性菌,按美国临床和实验室标准化研究所(CLSI)推荐的稀释法进行抗菌药物敏感性测定。采用WHONET 5.6和SPSS 25.0软件进行统计分析。结果共收集51家成员单位3163株革兰阳性菌,分离菌株数排在前5位的病原菌为金黄色葡萄球菌114.株(36.3%)、凝固酶阴性葡萄球菌928株(29.3%)、屎肠球菌369株(11.7%)、粪肠球菌296株(9.4.)和α-溶血链球菌192株(6.1%)。其中耐甲氧西林金黄色葡萄球菌(methicillin-resistant Staphylococcus aureus,MRSA)和耐甲氧西林凝固酶阴性葡萄球菌(methicillin-resistant coagulase-negative Staphylococci,MRCNS)流行率分别为26.4.(303/114.)和66.7%(619/928),未检测到对糖肽类和达托霉素耐药的葡萄球菌属;金黄色葡萄球菌对头孢比罗、利福平、复方磺胺甲噁唑、利奈唑胺、米诺环素及替加环素的敏感率均>95.0%。屎肠球菌分离率高于粪肠球菌,屎肠球菌对万古霉素及替考拉宁的耐药率均为0.5%(2/369),未检测到耐万古霉素粪肠球菌。我国南部地区的MRSA检出率低于其他地区(χ^(2)=14.578,P=0.002),而北部地区的MRCNS检出率高于其他地区(χ^(2)=15.195,P=0.002)。省级医院的MRSA和MRCNS检出率均高于地市级医院(χ^(2)=13.519和12.136,P<0.001)。人均GDP≥92059元地区的MRSA和MRCNS检出率均高于人均GDP<92059元地区(χ^(2)=9.969和7.606,P=0.002和0.006)。结论我国引起血流感染的革兰阳性菌中,以葡萄球菌属为主,MRSA整体流行率呈进一步下降趋势;屎肠球菌检出率超过粪肠球菌,耐万古霉素肠球菌仍然处于较低水平;我国不同地域的革兰阳性菌构成比和耐药谱略有不同,MRSA和MRCNS在省级医院和人均GDP≥92059元地区更为突出。
