工业操作系统借助资源实例化调度(RIS)技术管理制造资源时,会面临众多功能相似但服务质量各异的生产资源,导致资源选择和配置变得复杂。针对这一现状,提出了黄金柯西鲸鱼优化算法(GCWOA),该算法通过融合Tent混沌映射、黄金分割系数和柯西变异算子,实现对RIS问题的优化,提升服务质量。通过开展不同规模的RIS仿真实验验证,GCWOA展现出了显著的优势。相较于遗传算法、鲸鱼算法和2个改进鲸鱼算法,GCWOA的平均求解精度提升了5.6%,平均时间效率提高了2.35倍。以上结果充分证明了GCWOA在解决RIS问题上的高效性和实用性,为工业操作系统的资源管理提供了有力的优化工具。

背景宫颈癌是女性常见恶性肿瘤之一,其病因明确,通过规范筛查可以有效降低宫颈癌发病率。人乳头瘤病毒(HPV)检测是WHO推荐的首选宫颈癌筛查方法,了解成都市高危型人乳头瘤病毒(hrHPV)感染状况,对优化成都市宫颈癌筛查方案具有重要意义。目的分析成都市35~64岁参加宫颈癌筛查人群的hrHPV感染现状和宫颈病变患者的hrHPV亚型感染分布情况,探讨hrHPV阳性检出率的相关影响因素。方法从“成都市育龄妇女生殖健康数据库”收集2023年参加成都市免费宫颈癌筛查的459433例个案数据,分析不同hrHPV基因型感染总体分布情况以及宫颈病变患者的hrHPV亚型感染分布情况,比较不同特征人群hrHPV感染情况,并构建多水平Logistic回归模型分析hrHPV检出阳性情况的相关因素。结果459433例中,hrHPV阳性检出率为11.65%(53509/459433),hrHPV感染随年龄的增长呈上升趋势(χ_(趋势)^(2)=1501.082,P<0.001)。82.39%(131/159)的宫颈癌患者感染HPV 16或18亚型,以单纯感染HPV 16亚型为主(52.20%,83/159)。多水平Logistic回归分析结果显示,年龄、文化程度、婚姻状况、绝经状态、避孕方式、妊娠次数、分娩次数为hrHPV阳性检出情况的影响因素(P<0.05)。结论成都市女性hrHPV阳性检出率略低于全国平均水平。在筛查过程中,要重视健康教育与随访工作,特别是对HPV 16或18亚型阳性者的后续随访工作。开展宫颈癌筛查宣传工作时应特别关注年长者、文化程度较低者、未婚或离异/丧偶者、已绝经者、未避孕或采用避孕套外的其他避孕方式者、妊娠或分娩2次以上者等重点人群,加强宫颈癌防治核心知识、生殖健康知识等的宣传,提高妇女健康素养。

In this strategy, liquid metal(LM) with a shiny metallic luster and an excellent optical property, was introduced as a novel metallic paint and coating to packing products and achieved decorative effects. We report a straightforward method via spray printing to fabricate a consecutive ultra-thin LM film on various product substrates. Then, the flexible LM film was coated with a transparent varnish layer, which was rather convenient for the LM paint to be storing, using and transporting. The thicknesses(25 μm) and the shapes of LM paint were well controlled. The flop index(FI=105), and reflectance(R=88.8%) data of the LM metallic paint were characterized. The results indicated that the LM metallic paint could provide a sparkling appearance and an abounding glossy. The deoxidized LM has a pronounced positive influence on the surface roughness, appearance, reflectance,and metallic texture. The LM metallic paint was highly desirable for potential applications in automotive enamel, motorcycle,toy and high-quality industrial coatings in the near future.

We investigate the problem of direction finding for multiple Partially polarized(PP) electromagnetic signals, each of which possesses two spatial degrees of freedom. We use a uniform linear array of L sensors, where each consists of two co-located single-polarized *** exploiting the array geometry and its shift invariance property, we construct a set of data correlation sequences using the array output and its conjugate to transform the problem of direction finding to that of the estimation of complex sinusoid frequencies. The rank-2 signal correlation matrices of the PP signals become real-valued amplitudes of complex sinusoids, and thus, the rank-2 K signal subspace of the array output transforms to the rank-K signal subspace of the constructed correlation sequences. We show that only L = K + 1 sensors are needed to resolve K PP signals by solving the problem of estimation of sinusoid frequencies using subspace-based methods. The proposed method is also applicable to the scenario, where both Completely polarized(CP) and PP signals coexist, without the need of any prior information on the degree of polarization of the signal.

Among the wave energy converters (WECs), oscillating buoy is a promising type for wave energy development in offshore area. Conventional single-freedom oscillating buoy WECs with linear power take-off (PTO) system are less efficient under off-resonance conditions and have a narrow power capture bandwidth. Thus, a multi-freedom WEC with a nonlinear PTO system is proposed. This study examines a multi-freedom WEC with 3 degrees of freedom: surge, heave and pitch. Three different PTO systems (velocity-square, snap through, and constant PTO systems) and a traditional linear PTO system are applied to the WEC. A time-domain model is established using linear potential theory and Cummins equation. The kinematic equation is numerically calculated with the fourth-order Runge–Kutta method. The optimal average output power of the PTO systems in all degrees of freedom are obtained and compared. Other parameters of snap through PTO are also discussed in detail. Results show that according to the power capture performance, the order of the PTO systems from the best to worst is snap through PTO, constant PTO, linear PTO and velocity-square PTO. The resonant frequency of the WEC can be adjusted to the incident wave frequency by choosing specific parameters of the snap through PTO. Adding more DOFs can make the WEC get a better power performance in more wave frequencies. Both the above two methods can raise the WEC’s power capture performance significantly.

PdPt bimetallic catalysts that employ CeO2-modified carbon black as a support have been prepared using an organic colloidal method. PdPt/CeO2-C shows excellent performance toward the anodic oxidation of formic acid. The effects of varying both Pd to Pt ratio and CeO2 content have been investigated. The optimal Pd to Pt atomic ratio is 15, indicating that addition of small amounts of Pt can significantly enhance the activity of the catalyst. When the CeO2 content in the catalyst reaches as high as ~15 wt.%, the catalyst shows the maximum activity. Adding CeO2 not only enhances the catalytic activity of the material, but may also change the mechanism of its catalysis of the anodic oxidation of formic acid. PdlsPh/15CeO2-C exhibited 60% higher activity than Pd/C, and had a negative shift in onset potential of more than 0.1 V. Based on characterization by X-ray diffraction, X-ray photoelectron spectroscopy, thermogravimetric analysis and transmission electron microscopy, the interactions between the components are revealed and discussed in detail.
