作者： tingyang meng Yijing Xie Zongli Lin Charles L.Brown Department of Electrical and Computer Engineering University of Virginia Department of Automation Shanghai Jiao Tong University

In this paper, we investigate the static-consensus problem of linear multi-agent systems in the presence of bounded noises in the measurements of neighbors’ states over a connected undirected communication topology. We propose two types of consensus protocols, one using full state measurements of the neighbors and the other using partial state measurements of the neighbors. With the knowledge of the noise bounds, we show that, under these consensus protocols, the agents achieve static-consensus. A numerical example is presented to illustrate the theoretical results.

Outlier mining is an important aspect in data mining and the outlier miningbased on Cook distance is most commonly used. But we know that when the data have multicollinearity,the traditional Cook method is no longer effective. Considering the excellence of the principalcomponent estimation, we use it to substitute the least squares estimation, and then give the Cookdistance measurement based on principal component estimation, which can be used in outlier *** the same time, we have done some research on related theories and application problems.

On the gradient observational data of the atmospheric surface layer from September 1997 to December 1998 collected by two sets of Automatic Weather Station (AWS) installed in Gaize and Shiquanhe on the western Tibetan Plateau, mean surface roughness lengths at the two stations above are determined to be 2.7 and 2.9 cm, respectively. The bulk transfer coefficients each day are computed by the profile-flux method, means of the bulk transfer coefficient for momentum (i.e. drag coefficient) in 1998 are 4.83×10-3 and 4.75×103 at the two stations. The surface fluxes of momentum, sensible heat and latent heat each day are further estimated by the bulk formulas, annual mean of these fluxes is 3.4×10-2 and 1.8×102N/m2, 73.1 and 67.2 W/m2, 15.4 and 2.9 W/m2, respectively. The diurnal and seasonal variations are obtained by a composite method and the relationships among the heat transfers between land and atmosphere, plateau monsoon and plateau rain season are also discussed.

Philosophy based on epistemology is a philosophy of nouns which is restricted by the horizon of the knower, and cannot explain creation by human beings within its subjectobject frame. Therefore, we propose a philosophy of verbs that establishes itself on creational ontology and re-understands existence and origin from the horizon of the creator,so as to make that “I do”(facio) the starting point for the understanding of all order, ideas,and history that require consideration.

玫瑰花渣是玫瑰精油提取过程中产生的主要废弃物之一。以玫瑰花渣为原料，采用单因素实验结合BoxBehnken响应面法优化了超声辅助纤维素酶与果胶酶复合提取玫瑰花渣多糖的提取工艺，并对多糖体外抗氧化活性进行了研究。结果表明，在料液比为1:15，复合酶（纤维素酶:果胶酶=1:1）添加量为1.9%，酶解温度47℃，酶解时长84.5 min的条件下，玫瑰花渣多糖得率为4.308%±0.03%。体外抗氧化实验表明，玫瑰花渣多糖总抗氧化能力较强，当多糖溶液浓度为5 mg/mL时，其FRAP值为0.30，对DPPH·、ABTS+·的清除能力较强，清除率分别为98.93%和92.19%，对O2-·的清除能力较弱，清除率为24.93%。同时，玫瑰花渣多糖对DPPH·、ABTS+·、O2-·清除能力的IC50值大小分别为0.357、0.608、64.206 mg/mL。该研究为玫瑰花渣的回收再利用提供了理论依据。

I want to discuss the concept of “world” from a philosophical perspective. What's the best possible world? Let us pose this question to people. This was, and continues to be, an opportunity for people to construct the world — for the first men and women in their primitive state, as well as for all subsequent generations. Unfortunately, humans are unlikely to create the best possible world.

Unsatisfactory conductivity and volume effects have hindered the commercial application of siliconbased materials as advanced anode materials for high-performance lithium-ion batteries. Herein, nitrogen doped carbon silicon matrix composite with atomically dispersed Co sites(Si/Co-N-C) is obtained via the design of the frame structure loaded with nano-components and the multi-element hybrid strategy. Co atoms are uniformly fixed to the N-C frame and tightly packed with nanoscale silicon particles as an activation and protection building block. The mechanism of the N-C framework of loaded metal Co in the Si alloying process is revealed by electrochemical kinetic analysis and ex situ characterization ***, the nitrogen-doped Co site activates the intercalation of the outer carbon matrix to supplement the additional capacity. The Co nanoparticles with high conductivity and support enhance the conductivity and structural stability of the composite, accelerating the Li^(+)/Na^(+) diffusion kinetics. Density functional theory(DFT) calculation confirms that the hetero-structure Si/Co-N-C adjusts the electronic structure to obtain good lithium-ion adsorption energy, reduces the Li^(+)/Na^(+) migration energy *** work provides meaningful guidance for the development of high-performance metal/non-metal modified anode materials.

OBJECTIVE To develop an effectual method for treating hepatic metas-tasis from rectal cancer. METHODS A randomized control study of celiac artery perfusion plus transcatheter hepatic arterial chemoembolization (TACE) (observation group) and intravenous chemotherapy (control group) for 99 cases with hepatic me-tastasis from rectal cancer was performed. The perfusion was repeated once at 4 weeks after the first treatment of 52 cases in the observation group, and it was subsequently repeated at an interval of 2 or 3 months. Using intrave-nous administration, the perfusion was repeated once every 3 weeks with 47 cases in the control group. RESULTS Three months after treatment, the patients in the observation group who showed a relief or elimination of a former superior abdominal pain amounted to 70.6%, and those with a diminution of their intrahepatic mass reached 55.8%. In the control group, the patients with a relief or disappear-ance of hepatalgia reached 20%, and those with a diminution of their intrahe-patic mass reached 10.6%. The 1, 2 and 3-year survival rates were 80.8%, 46.2% and 25.0% in the cases of the observation group and 61.7%, 19.1% and 4.3% in the control group, respectively. CONCLUSION For the patients who failed to receive a surgical opera-tion on their hepatic metastasis from rectal cancer, celiac artery perfusion plus TACE is a more effective regimen for improvement of the clinical symp-toms and extension of the survival time, compared to intravenous chemo-therapy, and is a better choice for palliative therapy.
