In order to reduce the total resistance of a hull, an optimization framework for the bulbous bow optimization was presented. The total resistance in calm water was selected as the objective function, and the overset mesh technique was used for mesh generation. RANS method was used to calculate the total resistance of the hull. In order to improve the efficiency and smoothness of the geometric reconstruction, the arbitrary shape deformation （ASD） technique was introduced to change the shape of the bulbous bow. To improve the global search ability of the particle swarm optimization （PSO） algorithm, an improved particle swarm optimization （IPSO） algorithm was proposed to set up the optimization model. After a series of optimization analyses, the optimal hull form was found. It can be concluded that the simulation based design framework built in this paper is a promising method for bulbous bow optimization.

Ltd. School of Materials Science and Engineering Shanghai University School of Materials Science and Engineering Shanghai Jiao Tong University

The existence of residual austenite in weld metal plays an important role in determining the properties and dimensional accuracy of welded rotors. An effective corrosive agent and the metallographic etching process were developed to clearly reveal the characteristics of residual austenite in the weld metal of a 9Cr1MoNbV welded rotor. Moreover, the details of the distribution, shape, length, length-to-width ratio, and the content of residual austenite were systematically characterized using the Image-Pro Plus image analysis software. The results revealed that the area fraction of residual austenite was approximately 6.3% in the observed weld seam; the average area, length, and length-to-width ratio of dispersed residual austenite were quantitatively evaluated to be （5.5 ± 0.1）μm2, （5.0 ± 0.1）μm, and （2.2 ± 0.1）, re-spectively. The newly developed corrosive agent and etching method offer an appropriate approach to characterize residual austenite in the weld metal of welded rotors in detail.

国内能源效率分析及评价工作非常重要,目前相关研究都集中在相关政策和基础算法等方面,缺乏针对能源效率综合分析及评价系统的构建方法相关研究,尤其是针对下一代互联网技术的应用探究。本文首先介绍了基于IPV6的服务端局域通讯网络架构设计策略,构建了基于IPV6网络协议的能源效率大数据综合管控平台,平台不仅可以实现了国内各类能源效率大数据的收集,而且还可以利用特征识别方法确定能源效率影响因素。然后,基于典型数据挖掘和人工智能算法集,可以方便建立分类预测和聚类分析的应用模型;平台既可对各省份能源效率高低进行分类预测,又可将能源效率高的省份与效率低的省份区分开来,实现了对全国整体能源效率的综合分析与评价。这对我国能源互联网发展建设、利用大数据技术提升能源综合利用效率具有一定的借鉴意义。

Large animals(non-human primates, livestock and dogs) are playing important roles in biomedical research, and large livestock animals serve as important sources of meat and milk. The recently developed programmable DNA nucleases have revolutionized the generation of gene-modified large animals that are used for biological and biomedical research. In this review, we briefly introduce the recent advances in nuclease-meditated gene editing tools, and we outline these editing tools’ applications in human disease modeling, regenerative medicine and agriculture. Additionally, we provide perspectives regarding the challenges and prospects of the new genome editing technology.

The neutrino burst detected during supernova SN 1987A is explained in a strangeon star model, in which it is proposed that a pulsar-like compact object is composed of strangeons （strangeon： an abbreviation for ＂strange nucleon＂）. A nascent strangeon star＇s initial internal energy is calculated, with the inclusion of pion excitation （energy around 1053 erg, comparable to the gravitational binding energy of a collapsed core）. A liquid-solid phase transition at temperature - 1 - 2 MeV may occur only a few tens of seconds after core collapse, and the thermal evolution of a strangeon star is then modeled. It is found that the neutrino burst observed from SN 1987A can be reproduced in such a cooling model.

随着风电渗透率的不断增加,电网的安全稳定运行不可忽视风电爬坡对其产生的影响。然而,传统的爬坡事件识别方法大多只考虑了源侧的风电场输出功率信息,综合考虑电网侧和负荷侧信息的研究相对较少。本文给出了一种结合源-网-荷信息的风电爬坡综合识别方法:首先,利用源侧风电场输出功率曲线与对应的电网负荷侧曲线获取了相对风电功率曲线,在相对风电功率曲线上定义风电爬坡事件,并根据电网频率给出了爬坡阈值的设定策略。然后,通过对所收集的实际风电场输出功率数据和电网负荷数据进行综合分析,验证了本方法的合理性和有效性。最后,通过对相对风电功率的定义进行合理延伸,首次提出了一种结合广义源-网-荷信息的风电爬坡事件综合识别方法。
