Forming limit curve（FLC）is an effective tool to evaluate the formability of sheet *** accurate FLC prediction for a sheet metal is beneficial to its engineering application.A quenched and partitioned steel,known as QP980,is one of the 3rd generation advanced high strength steels and is composed of martensite,ferrite and a considerable amount of retained austenite（RA）.Martensite transformation from RA induced by deformation,namely,transformation induced plasticity（TRIP）,promotes the capability of work hardening and consequently *** tests were carried out to obtain the experimental forming limit strains with the aid of digital image correlation *** electron microscopy（SEM）was employed to examine the fracture morphologies of Nakazima specimens of the QP980 *** observed dimple pattern indicated that tensile stress was the predominant factor which led to failure of QP980 ***,maximum tensile stress criterion（MTSC）was adopted as the forming limit *** predict the FLC of QP980 steel,Von-Mises yield criterion and power hardening law were adopted according to the tested mechanical properties of QP980 *** were compared with those derived from other three representative instability theories,*** criterion,Storen-Rice vertex theory and Bressan-Williams model,which shows that the MTSC based FLC is in better agreement with the experimental results.

Energy harvesting technologies allow wireless devices to be recharged by the surrounding environment, providing wireless sensor networks (WSNs) with higher performance and longer lifetime. However, directly building a wireless sensor network with energy harvesting nodes is very costly. A compromise is upgrading existing networks with energy harvesting technologies. In this paper, we focus on prolonging the lifetime of WSNs with the help of energy harvesting relays (EHRs). EHRs are responsible for forwarding data for sensor nodes, allowing them to become terminals and thus extending their lifetime. We aim to deploy a minimum number of relays covering the whole network. As EHRs have several special properties such as the energy harvesting and depletion rate, it brings great research challenges to seek an optimal deployment strategy. To this end, we propose an approximation algorithm named Effective Relay Deployment Algorithm, which can be divided into two phases: disk covering and connector insertion using the partitioning technique and the Steinerization technique, respectively. Based on probabilistic analysis, we further optimize the performance ratio of our algorithm to (5 + 6/K) where K is an integer denoting the side length of a cell after partitioning. Our extensive simulation results show that our algorithm can reduce the number of EHRs to be deployed by up to 45% compared with previous work and thus validate the efficiency and effectiveness of our solution.

目的基于定量蛋白质组学技术明确西黄丸抗乳腺增生(hyperplasia of mammary glands,HMG)中乳腺组织的差异蛋白并验证,探讨其作用机制。方法将SD大鼠随机分为空白组、模型组和西黄丸组,每组10只。除空白组外,肌注雌孕激素建立HMG大鼠模型,为期30 d。给药西黄丸14 d后,观察各组大鼠表观形态变化,HE染色观察乳腺组织病理改变,定量蛋白质组学技术筛选各组差异表达蛋白(differentially expressed proteins,DEPs),并进行生物信息学分析和Western blot验证。结果与模型组比较,西黄丸组表观病理形态明显改善,大鼠乳头高度直径明显降低(P<0.01),组织病理程度明显缓解。定量蛋白质组学鉴定出乳腺组织4299个DEPs,对西黄丸组与空白组相对模型组变化一致的14个DEPs进行生物信息学分析,发现与肌肉系统过程的调节、肌肉收缩调节、DNA复制和DNA复制启动前过程有关。Western blot结果表明,与模型组比较,西黄丸组大鼠乳腺组织ACLY与ALDOC蛋白表达水平明显降低,BIN1蛋白表达水平明显增加(P<0.01)。结论西黄丸可能通过调控BIN1、ACLY及ALDOC蛋白水平,调控DNA复制、DNA复制启动前和肌肉系统过程的调节、肌肉收缩调节等途径发挥抗HMG作用。

绿色研发补贴是指中央或地方政府鼓励企业从事节约资源和保护环境等绿色技术创新活动的财政补贴。本文以企业的迎合行为为视角,基于中国上市公司2011—2020年的面板数据,采用双向固定效应模型实证检验了绿色研发补贴对绿色技术创新数量和质量的激励效应。研究发现:①绿色研发补贴能促进企业绿色技术创新;②绿色研发补贴对绿色技术创新激励存在异质效应,表现为对绿色技术创新数量的促进作用优于质量;③企业对绿色研发补贴存在迎合行为,这导致绿色研发补贴产生“强数量、弱质量”的激励异质效应;④绿色研发补贴的激励异质效应受到行业污染程度和环境规制强度的差异影响,表现为相较于重污染行业,绿色研发补贴对非重污染行业的激励效果更优,但迎合行为的存在也会导致“强数量、弱质量”的激励效应;环境规制强的地区绿色研发补贴能促进企业绿色技术创新“增量提质”,表明强规制能制约企业策略性创新的迎合行为。本文研究不仅深化了绿色研发补贴的量化研究,而且识别并检验了迎合行为的扭曲效应,为完善绿色研发补贴标准的制定和发放以及推动企业高质量绿色技术创新提供了微观经验支撑和对策建议。
