作者： Yutong Sun Youfeng Su he cai College of Mathematics and Computer Science Fuzhou University School of Automation Science and Engineering South China University of Technology

In this paper, the time-varying demand power sharing problem of a grid-connected AC microgrid is *** autonomous leader system is introduced to capture the time-varying demand. We first convert the power sharing problem into a tracking problem of a leader-follower multiagent system by introducing a so-called canonical model. Then we show the exponential stability of the closed-loop system, hence reaching the desired bounded time-varying power sharing. The simulation results show that the theoretical part is supported by practice.

太赫兹时域光谱（THz-TDS）技术对物质进行无损检测是太赫兹应用领域的一个研究热点。针对近日报道检查出部分麦当劳的＂麦乐鸡＂添加剂中含有的一种化学成分——特丁基对苯二酚（TBHQ）含量超标,应用太赫兹无损检测技术对其作定性识别。测得该种化学成分在0.2~2.2 THz的吸收谱和折射率曲线,并将其以不同比例与面粉均匀混合,测得混和物和面粉在0.2-2.2 THz的吸收谱。同时对TBHQ进行理论模拟作为对比。结果表明,通过太赫兹波段吸收曲线的特征差异检测TBHQ是可行的,为无损食品添加剂的检测提供一种新型的方法。

2011-2013年,在天津古海岸与湿地国家级自然保护区6种生境中设置31个样方,利用铗日法调查啮齿动物,同时记录各个样方10个环境因子。调查期间共捕获啮齿动物7种157只,总铗捕率为1.69%。优势种为黑线姬鼠、褐家鼠和大仓鼠,铗捕率分别为0.59%、0.25%和0.23%。铗捕率以人类居住区和农田最高,水域岸边次之,其它生境较低;种数和多样性较高值均出现在人类居住区和农田,最低值在盐碱地;均匀度除了水域岸边较低外,其它生境较高,表明啮齿动物群落结构变化明显。利用余冗分析法对啮齿动物群落与环境因子之间关系进行分析,结果表明农作物距离、草本盖度、水体盐度、灌丛高度是影响古海岸湿地啮齿动物群落结构变化的关键环境因子。

AIM:To explore the potential of β-elemene as a radiosensitizer for gastric cancer cells and the underlying ***:SGC7901,MKN45,MKN28,N87,and AGS human gastric cancer cell lines were used to screen for radioresistant gastric cancer cell lines. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium(MTT) assay was used to determine the effects of β-elemene and IPA-3 on cell viability in MKN45 and SGC7901 gastric cancer cell lines. A clonogenic survival assay and annexin V-FITC/PI apoptosis detection assay were used to evaluate cellular radiosensitivity and radiation-induced cell death,respectively. A proteomic method,isobaric tags for relative and absolute quantitation(i TRAQ),was employed to screen the proteins regulated by β-elemene pretreatment prior to ionizing radiation(IR) in SGC7901 gastric cancer cell line. IPA-3 was used as a specific small molecule inhibitor of p21-activated protein kinase 1(Pak1) to target Pak1 signaling. Protein levels of PAK1IP1(p21-activated protein kinase-interacting protein 1),total Pak1(t-Pak1),phospho-Pak1(T423),phospho-ERK1/2( Thr202/Tyr204),and cleaved caspase-3(17 k Da) were assessed by western ***:MKN45 and SGC7901 gastric cancer cell lines were relatively more resistant to IR. β-elemene pretreatment decreased clonogenic survival following IR in MKN45 and SGC7901 gastric cancer cell lines. Additionally,β-elemene pretreatment prior to IR increased radiation-induced cell death compared with IR alone in MKN45(10.4% ± 0.9% vs 34.8% ± 2.8%,P he level of cleaved caspase-3(17 k Da). Through i TRAQ analysis and western blot validation,we found that β-elemene upregulated PAK1IP1 and downregulated phospho-Pak1(T423) and phosphoERK1/2 in SGC7901 gastric cancer cells. IR increased the level of phospho-Pak1(T423). Pretreatment with β-elemene decreased radiation-induced Pak1 and ERK1/2 phosphorylatio

According to the demands for rapid and accurate burdening system, an automation forage burdening system was designed using a programmable logic controller （PLC） as the main controller. The communication between PLC and force control was achieved by485 bus. This system have many functions such as recipe setup, burdening control, feed mixture, report printing, and remote alarm. The remote surveillance and control of burdening system were realized. The practice shows that the system had high precision and short cycle, and great control effect was obtained.

The aim of this work has been to evaluate whether a diagnostic protocol based on the joint use of mammography and 99mTc-MIBI scintimammography can help to distinguish the lesions and to reduce the number of biopsies required in patients with suspected breast cancer. A total of 58 women were evaluated by palpation, mammography, scintimammography. Twenty-four patients were scintimammographed with 99mTc-MIBI at 10min after injection. Thirty-four patients were taken doublephase scintimammography with 99mTc-MIBI 10min and 60-90min after injection. Based on mammography, the supicion degrees of malignancy were rated, and 30 results of malignancy were confirmed by histopathology. Based on mammography, 18 lesions were considered to be most probably benign (of which 3 were histopathologi-cally breast cancer), 19 as indeterminate (of which 9 were histopathologically breast cancer), and 21 as malignant (of which 18 were histopathologically breast cancer). The results of early and delayed phases 99mTc-MIBI scintimammography were the same. The sensitivity, specificity and accuracy of scintimammography were 74.29%, 86.96% and 79.31%, respectively. Scintimammography gave 16 correct diagnosis in 19 mammogram indeterminate (84.2%) and demonstrated 5 out of 8 cases axillary lymph nodes metastasis (62.5%). These studies show that 99mTc-MIBI scintimammography used as a complementary testing technique to mammography is useful in the examination of patients with suspected breast cancer. The adoption of a joint mammography-scintimammography diagnostic protocol conld considerably reduce the number of biopsies performed in patients with lesions of indeterminate mammographic suspicion of malignancy.

广东南海本田工人的罢工标志着农民工的利益诉求正从"底线型"利益向"增长型"利益转变。"底线型"利益受法规保护并有清晰的利益标准,"增长型"利益没有正式的法规保护和清晰的利益标准。"底线型"利益纠纷,个体可以通过仲裁和诉讼来解决,而"增长型"利益纠纷没有仲裁和诉讼的通道,只能依靠集体力量得到解决。虽然集体谈判日益成为解决"增长型"利益纠纷的机制,但是"谈判"只是实现"增长型"利益诉求的必要条件,并不当然地是充分条件,除非有"集体行动"的介入。建立社会主义市场经济下的劳资关系秩序,必须理清罢工的法律地位问题、罢工的权利边界问题、工会的组织效能问题。面对"底线型"利益纠纷,政府扮演的是监督者和执法者的角色,面对"增长型"利益纠纷,政府扮演的是协调者的角色。

对一行为触犯二法条的情形进行划分,其必要性在于它不能适用一个统一的处罚原则,根据量刑的全面评价原则可将其划分为想象竞合与法条竞合。在法条竞合中,其中某一法条可全面评价行为的社会危害;在想象竞合中,要全面评价行为的社会危害必须同时考虑二法条。想象竞合和法条竞合划分的通行观点并不能反映全面评价原则。根据全面评价原则,本文对想象竞合和法条竞合划分的几种具体情形进行了探讨。
