为了研究纳米流体材料在降低高桩码头的动力响应、减轻码头震害领域的应用潜力，基于开源有限元计算平台OpenSees,建立了加入阻尼器的高桩码头二维有限元模型，对比分析了传统黏滞阻尼器和纳米流体阻尼器对高桩码头抗震性能的影响，评估了纳米流体材料对高桩码头的减震效果。结果表明：纳米流体阻尼器比黏滞阻尼器具有更好的限制桩顶侧向变形的能力；相比于黏滞阻尼器，纳米流体阻尼器可以更好地降低陆侧桩的桩顶曲率；加入纳米流体阻尼器的码头桩顶耗能小于加入黏滞阻尼器的码头桩顶耗能。

To acquire a competitive advantage in the expanding market, manufacturing enterprises should be able to manage their supply chains as effectively as possible. It is now becoming popular to model supply chains as multi-agent systems and use discrete event simulation to learn more about their behaviors or investigate the implications of alternative configurations. In order to enhance the computational efficiency and keep the simulation credibility, this paper proposes a message-driving formalism for the simulation of multi-agent supply chain systems. Through the message-driving formalism, the problem of shared variables is addressed and the parallel operation of agents is implemented. Simulation experiments with a prototype implementation show that the message-driving formalism is able to provide credible results in significantly less simulation time.

A New Model for Location Problem with Stochastic Demands

Small moleculeα-methylene-γ-butyrolactone,an evolutionarily conserved moiety in sesquiterpene lactones,ameliorates arthritic phenotype via interference DNA binding activity of NF-κB

ICSSSM'04国际会议

作者： Juqi LIU yueting chai Yi LIU Automation Department Tsinghua University Beijing 100084 China

＜正＞ This article proposes a new model which integrates the service level constraints （product available rate） and considers the uncertainty of customer demands at the same time. The customer demands are described with normal distribution functions. We try to locate the facilities and determine the customers assigned to them simultaneously. The goal is to minimize the total logistics cost and meet the specific constraints of product available rate at each facility. In order to describe the capacity constraints properly, we introduce chance constraints with confidence level β. Our problem is thus a strategic decision problem under uncertainty and can be viewed as an extension to the traditional capacitated location problem with fixed cost. We also present two hybrid intelligent algorithms to find the near-optimal solutions. Extensive computational results across a variety of problem structures are reported.

Rheumatoid arthritis(RA)is an inflammatory disease accompanied by abnormal synovial microenvironment(SM).Sesquiterpene lactones(SLs)are the main anti-inflammatory ingredients of many traditional herbs utilized in RA treatment.α-Methylene-γ-butyrolactone(α-M-γ-B)is a core moiety that widely exists in natural *** study was designed to investigate the anti-arthritic potential ofα-M-γ-B as an independent small molecule in vitro and in vivo.α-M-γ-B exhibited stronger electrophilicity and anti-inflammatory effects than the other six analogs.α-M-γ-B inhibited the production of pro-inflammatory mediators via repolarizing M1 macrophages into M2 *** transcriptome sequencing suggested thatα-M-γ-B regulated the immune system ***,α-M-γ-B attenuated collagen type II-induced arthritic(CIA)phenotype,restored the balance of Tregs-macrophages and remodeled SM via repolarizing the synovial-associated macrophages in CIA ***,althoughα-M-γ-B did not prevent the trans-nucleus of NF-κB it interfered with the DNA binding activity of NF-κB via direct interaction with the sulfhydryl in cysteine residue of NF-κB p65,which blocked the activation of NF-κ*** of NF-κB reduced the M1 polarization of macrophage and suppressed the synovial hyperplasia and angiogenesis.α-M-γ-B failed to ameliorate CIA in the presence of N-acetylcysteine or when the mice were subjected to the macrophage-specific deficiency of *** conclusion,α-M-γ-B significantly attenuated the CIA phenotype by directly targeting NF-κB p65 and inhibiting its DNA binding *** results suggest thatα-M-γ-B has the potential to serve as an alternative candidate for treating *** greater electrophilicity ofα-M-γ-B,the basis for triggering strong anti-inflammatory activity,accounts for the reason whyα-M-γ-B is evolutionarily conserved in the SLs by medical plants.

针对带不等式约束的非线性规划问题,提出了一个混合遗传算法。该算法分为全局探测和局部开采两个阶段,全局探测阶段是通过在有潜力的小生境内嵌入单纯形搜索,快速确定有前景的区域;而局部开采阶段则是在最有前景的区域进行单纯形搜索。该算法增强了局部搜索能力并同时保持种群的多样性,有效地解决了遗传算法的过早收敛和局部搜索能力弱的问题。典型非线性规划算例验证了混合算法的效率、精度和可靠性。

从形式标记视角来看,上古汉语是区分对象与受事的:(1)动词原本就有且只有一个域内论元时,可以是受事,也可以是对象,皆无标记;(2)动词有两个域内论元时,受事无标记,对象通常以动词异读去声或“于/於”为标记;(3)无域内论元的不及物动词,可以借助异读去声或“于/於”这两种标记引进对象论元。从用例来看,随着标记脱落以及词义发展等,出现了大量无标记的对象论元,受事与对象的区分变得模糊,以有标记的用例为基础并结合异读模式解析,或有可能找出二者的大致界线。
