A Theorem on Grid Access Control

The current grid security research is mainly focused on the authentication of grid systems. A problem to be solved by grid systems is to ensure consistent access control. This problem is complicated because the hosts in a grid computing environment usually span multiple autonomous administrative domains. This paper presents a grid access control model, based on asynchronous automata theory and the classic Bell-LaPadula model. This model is useful to formally study the confidentiality and integrity problems in a grid computing environment. A theorem is proved, which gives the necessary and sufficient conditions to a grid to maintain confidentiality. These conditions are the formalized descriptions of local (node) relations or relationship between grid subjects and node subjects.
Equivalent Time-Domain Representation and Uplink Channel Estimator for Multicarrier CDMA Systems

Many blind channel estimation methods have been proposed for direct sequence (DS) code-division multiple access (CDMA) systems, so we can certainly use them to estimate the finite impulse response (FIR) channel for the multi-carrier (MC-) CDMA system. In this paper, the MC-CDMA system is interpreted as an equivalent time-domain DS-CD-MA system with specific spreading codes. Then, an equivalently time-domain blind channel estimator is derived for the uplink MC-CDMA, which is based on second-order statistics of the received data. By exploiting singular value decomposition (SVD) and the finite alphabet property of transmitted symbols, the time-domain channel impulse response (CIR) for the uplink MC-CDMA can be accurately identified. Computer simulations illustrate both the validity and the overall performance of the proposed estimator.
Gravitational Gauge Interactions of Scalar Field

Quantum gauge theory of gravity is formulated based on gauge principle. Because the Lagrangian has strict local gravitational gauge symmetry, gravitational gauge theory is a perturbatively ienormaliza,hle quantum theory. Gravitational gauge interactions of scalar field are studied in this paper, In quantum gauge theory of gravity, scalar Reid minimal couples to gravitational field through gravitational gauge covariant derivative. Comparing the Lagrangian for scalar Geld in quantum gauge theory of gravity with the corresponding Lagrangian in quantum Gelds in curved space-time, the definition for metric in curved space-time in geometry picture of gravity can be obtained, which is expressed by gravitational gauge Geld. In classical level, the Lagrangian and Hamiltonian approaches are also discussed.
SPATIAL STRUCTURE EVOLUTION OF SYSTEM OF RECREATION BUSINESS DISTRICT—A Case of Suzhou City

The growing attention on urban tourism was very widespread. There are two angles to study urban tourism: supply-side and demand-side. And the supply-side of the tourism remains very important. The RBD (Recre-ation Business District) is a useful framework to understand the components of urban tourism and how they fit to-gether. The paper begins with a review on the RBD and the spatial structure of tourism in urban areas and then at-tempts to develop a more general understanding of the spatial structure evolution of RBDs in a tourist-historic city— Suzhou. The spatial structures and functions of the RBDs in Suzhou are examined, based on field observations, inter-views with city officials and industry leaders, and a review of available documents. The urban tourism of Suzhou has developed in a range of contexts, that various types of RBDs have emerged as a result of different urban develop-ment strategies. The spatial structure has evolved from the past "Single-cored Structure" to "Double-cored Structure" at present, and then to "Chain Structure" in the future. The spatial form and evolution of RBD in Suzhou are closely relative with its urban spatial expansion. Urban area dispersal is the prerequisite of the emergence of the RBD. Plan-ning and constructing the RBD becomes a new impetus to urban growth or renewal. Finally, a number of strategies for planning and developing the RBD in Suzhou are suggested. The different RBDs should adopt different strategies. Intensification can be the possible strategy for the RBDs in the ancient city. Accreting with the urban theme park or engrafting on the Jinji Lake is suggested respectively for the RBD in the Suzhou New District and the Suzhou Indus-trial Park.
Equations of Electromagnetic Self-Consistency in a Plasma

The set of equations governing a system consisting of En electromagnetic field plus charges in it is obtained by varying the appropriate action. It is not assumed that the currents are given, which in fact leads to the Maxwell equations governing the fields. Nor is it assumed that tie fields, are given, which in fact would lead to the determination of the motions of the charges (the currents) through the Lorentz force. On the contrary, currents and fields are left free to interplay, and they can foe found simultaneously from the equations obtained.

APPLICATION OF ANALYTIC HIERARCHY PROCESS TO ASSESSING THE ECOLOGICAL VULNERABILITY OF WETLANDS IN THE JIANGHAN PLAIN

Wetlands in the Jianghan Plain are important components of wetland types in lake area in the middle and lower reaches the Changjiang (Yangtze) River and they fulfill many uses and functions related to hydrology, waste assimilation, ecosystem productivity and biodiversity. Owing to natural factors and human activities, especially excessive reclamation from lakes, the shrinking process of the lakes has been accelerated. Wetland ecosystem has shown the characteristics of vulnerability. According to the analysis of wetland ecological function in the Jianghan Plain, this paper presented an index system related to productivity, stability and environmental capacity. By using the method of Analytic Hierarchy Process, we computed the values of the relative weights of the indexes, and evaluated the vulnerability level of the wetland ecosystem by the method of multi-indexes. The case study showed that the fragile extent of wetland ecosystem in the Jianghan Plain is 5.6. This means that the wetland ecosystem in the Jianghan Plain is laid to the state of middle vulnerability. Therefore, the wetland conservation and eco-rehabilitation in the Jianghan Plain should be paid attention to.
Effects of Gamichunggantang on hyperlipidemia 

AIM: To evaluate the therapeutic effects of Gamichunggantang (GCT) on hyperlipidemia through high cholesterol diet model. GCT is an Oriental herbal medication, which has been used for the treatment of fatty liver, hyperlipidemia or alcoholic liver disease in Daejeon University Oriental Hospital, Korea since 1999. METHODS: Rats were fed with high cholesterol diet for 4 weeks and GCT was administrated for 2 weeks from 2 weeks later in experimental days. The levels of serum total cholesterol, HDL-cholesterol, and triglyceride were analyzed every week. Absolute and relative liver weight to body, and histophathological changes were determined at last day. And, lipid metabolism-related gene expressions (ACAT and DGAT) in liver tissue were analyzed by using RT-PCR. RESULTS: In GCT group, TG levels were reduced at 3 and 4 weeks after GCT administration (39.4 %, P<0.05 and 36.3 %, P<0.01 respectively). Total cholesterol levels also were reduced at 3 weeks (20.5 %, P<0.05) and 4 weeks (35.86 %, P<0.01) after GCT administration, but HDL-cholesterol levels were increased significantly (P<0.05) at 3 weeks (14.7 %) and 4 weeks (25.5 %) compared with hyperlipidemia-induced group without GCT. In the GCT treated group, liver weight was lower and lipid accumulation was decreased in histological finding. ACAT gene expression was suppressed compared with hyperlipidemia-induced group but not DGAT. CONCLUSION: GCT possesses preventive or therapeutic effects on diet-induced hyperlipidemia by inhibiting the intestinal absorption and storage of exogenous and endogenous cholesterol.

Based on quantum chemical calculations, TLSER model (theoretical linear solvation energy relationships) and atomic charge approach were applied to model the partition properties( water solubility and oetanol/water partition coefficient) of 96 aromatic sulfur-containing carhoxylutes, including phenylthio, phenylsulfinyl and phenylsulfonyl earbnxylutes. In comparison with TLSER models, the atomic charge models arc more accurate and reliable to predict the partition properties of the kind of compounds. For the atomic charge models, the molecular descriptors are molecular surface area(S) , molecular shape(O) , weight(M_w), net charges on carnoxyl group(Q_(OC)), net charges of nitrogen atoms(Q_N), and the most negative atomic charge(q~-) of the solute molecule. For water solubility (log S_w) and octanol/waler partition coefficient log K_(ow)) . the correction coefficients r_(adj)~2(adjusted for degrees of freedom) are 0.936 and 0.938, and the standard deviations are 0.364 and 0.223, respectively.
INDUSTRIAL TRANSFORMATION OF SHENYANG CITY

Industrial transformation represents a unique economic phenomenon in China's regional economy, and old industrial city reconstruction has long been a key problem that affects state security. As a typical old indus-trial city in China, Shenyang established its heavy industrial city position in the First Five-year Plan period (1953-1957), and this industrial structure has been consolidated for a long time. After 1978, Shenyang began its long last-ing industrial reconstruction in an all-round way by 3 main initiatives including restructuring economic system, up-grading traditional industrial technology and developing high-tech industry. In the end of the 1990s, it could be identifled that remarkable structural changes took place in city economy at large as well as individual industrial sector. According to the GDP proportion change, Shenyang is on the way to a high level industrial structure. The secondary industry also engendered significant shifting as smelting and textile industry declined sharply but IT industiy increased largely. Although the ratio of the heavy industry to the light industry changed periodically, the heavy industrial output value most time kept a high proportion over 60% of the gross industrial output value in the past five decades. Shenyang has favorable conditions for developing equipment manufacturing industry, but it should carry out the program by establishing its leading role in urban economy plan, building "Theme Industrial Parks", improving Tiexi Industrial Zone, removing any kind of system barrier, enlarging private and other ownerships economy and improving technology, marketing and management by IT application. In response to economy globalization, Shenyang needs to expand the cooperation worldwide and improve the cohesion with surrounding cities.

ANALYSIS OF DRIVING FORCES ON THE CHANGE OF HISTORICAL FARMLAND USE IN SHANDONG PROVINCE DURING THE QING DYNASTY (1644-1911)

How land-cover has been changed by human use over the last 300 years is one of the five overarching questions guiding the Land-use/Cover Change (LUCC) Science/Research Plan. China has variety of historical documents providing unique data superiority. So the characteristics of farmland area in Shandong Province during the Qing Dynasty (1644-1911) are summarized firstly; 1) the rising trend of farmland area was striking; 2) farmland area had remarkable fluctuation; 3) farmland area per capita decreased dramatically; 4) wasteland reclamation index increased rapidly. Then, the driving forces of farmland area change are analyzed. It is concluded that natural and human factors are jointly influential. Among the driving forces, human dimensions are the main factors of farmland area change, which direct the general tendency of the changes mentioned above. And the natural factors influence the stability of farmland area as well. Variation of the natural factors would act as the major contributory factor to farmland area change during years or periods of abrupt climatic changes, or during the intensive occurring periods of natural hazards. Besides, the passive aspects of human factors, such as war chaos also influenced the fluctuation of the farmland area. This research indicates that it is feasible to study the land-use/cover change by Chinese historical literatures, which has huge potential to provide a comprehensive picture of the growing dominance of human land-use and land-cover pat-terns that can be used in many global change research projects.

Mechanism of Coalescence Demulsification with Microfiltration Membrane

A study on the membrane coalescence demulsification was carried out with four working systems of water/n-butyl alcohol, water/n-octanol, water/30%TBP(in kerosene) and water/kerosene. The membranes made of polytetrafluoroethylene (PTFE) with 1.0 μm pore size were used. The results indicated that the excellent demulsification efficiency for emulsions with various oil contents was obtained. A conductivity probe was used to study the demulsification mechanism. An electrode probe was designed and used to determine the oil content near the membrane surface. The obtained data showed that the oil content in the permeated stream was much higher than that in the feed emulsion. A physical mechanism to explain the membrane demulsification was put forward.
Gully-specific debris flow hazard assessment in china

Techniques of gully-specific debris flow hazard assessment developed in four periods since the end of the 1980s have been discussed in the present paper. The improvement for the empirical assessment method is the sectionalized function transformation for the factor value, rather than the classified logical transformation. The theoretical equation of the gully-specific debris flow hazard is expressed as the definite integral of an exponential function and its numerical solution is expressed by the Poisson Limit Equation. Current methods for assessment of debris flow hazard in China are still valid and practical. The further work should be put on the study of the reliability (or uncertainty) of the techniques. For the future, we should give a high priority to the relationship between debris flow magnitude and its frequency of occurrence, make more developments of prediction model on debris flow magnitude, so as to finally reach the goal of assessing the hazard of debris flow by theoretical model, and realize both actuality assessment and prediction appraisal of debris flow.
Total Nuclear Reaction. Cross Section Induced by Halo Nuclei and Stable Nuclei

We develop a method for calculation of the total reaction cross sections induced by the halo nuclei and stable- nuclei. This approach is based on the Glauber theory, which is valid for nuclear reactions at high energies. It is extended for nuclear reactions at low energies and intermediate energies by including both the quantum correction and Coulomb correction under the assumption of the effective nuclear density distribution. The calculated results of the fcotai reaction cross section induced by stable nuclei agree well with 30 experimental data within 10 percent accuracy.Tie comparison between the numerical results and 20 experimental data for the total nuclear reaction cross section induced by the neutron halo nuclei and the proton halo nuclei indicates a satisfactory agreement after considering the halo structure of these nuclei, which implies quite different mean fields for the nuclear reactions induced by halo nuclei and stable nuclei. The halo nucleon distributions and the root-mean-square radii of these nuclei can be extracted from the above comparison based on the improved Glauber model, which indicates clearly the halo structures of these nuclei. Especially, it is clear to see that the medium correction of the nucleon-nucleon collision has little effect on the total reaction cross sections induced by the halo nuclei due to the very weak binding and the very extended density distribution.

Photocatalytic degradation of phenol in aqueous solution using TiO_2/Ti thin film photocatalyst

In order to clarify the respective role of the UV light, catalyst, external bias as well as their combined effects on the photodegradation process and to clarify the photocatalytic mechanism under different experimental conditions, a series of experiments were conducted in a shallow pond photoreactor with an effective volume of 100mL using TiO_2/Ti thin film prepared by anodization as photocatalyst. A 300W UV lamp (E_(max) = 365nm) was used as side light source. The effect of light intensity on photocatalysis was also conducted. The results show that photocatalytic oxidation is an effective method for phenol removal from waters. The degradation rate can be improved by applying an anodic bias to the TiO_2/Ti film electrode, phenol can not be decomposed under only 365nm UV light irradiation even in the presence of hydrogen peroxide. In the range of our research, the phenol removal rate can be described in terms of pseudo-first order kinetics.
Secure Web Transaction with Anonymous Mobile Agent over Internet

A major problem of mobile agents is their apparent inability to authenticate transactions in hostile environments. In this paper, a new secure anonymous mobile agent scheme is proposed for the prevention of agent tempering without compromising the mobility or autonomy of the agent. In the scheme, a mobile agent can produce valid signature on website's bid (it means to transact a contact with the web site) on behalf of its customer, without revealing the customer's real private key. In addition, the anonymity of the customer is also achieved when its agent transacts with the websites. Furthermore, the customer who issues a malicious agent or denies the transaction can be identified and detected by Agent Management Center (AMC). Therefore, the scheme is practical in the future electronic commerce over Internet.

MD simulation for nanocrystals

Molecular dynamic (MD) provided an \textit{ab initio} simulation for nano-scale mechanical behavior of materials, provided that the inter-atomic potential is accurately prescribed. MD is particularly suitable in simulating the formation, the deformation, and the evolution of nanocrystals under a fast strain rate. To tackle large scale system and nano-seconds time duration, parallel algorithm is desired. The present paper reviews the recent advances in MD simulation for nanocrystals with attention focused on the applications toward nanomechanics. The examined issues are: formation of nanocrystalline metals, nanoindentation on nanocrystals, fast deformation of nanocrystals, order-disorder transition, and nano-particle impact.
Nature of (001) and (00(1-bar)) faces and flocculation flotation of kaolinite

Flotation mechanism of kaolinite was investigated through flotation test, SEM analysis and quantum chemical simulation calculation. It is shown that the (001) face of kaolinite easily adsorb cationic collector to exhibit hydrophobicity; the (00(1-bar)) face is easily interacted with the reagent carrying the group of high electronegativity (-O-, -N-, F-) to show hydrophilicity. The cationic and anionic polyacrylamide are adsorbed onto the (00(1-bar)) face of kaolinite and the flocculation of kaolinite particles may take place; the (001) faces are exposed to interact with cationic collector to be rendered hydrophobicity. Thus, the macromolecules can evidently enhance the flotation of kaolinite in alkaline media.
Momentum Distribution of a Fragment and Nucleon Removal Cross Section in the Reaction of Halo Nuclei

Recently the research on the halo structure of drip-line nuclei has shown some interesting properties of the existence of one or more halo nucleons. In the framework of few-body Glauber model, the momentum distribution of a fragment and nucleon removal cross section in the reaction of halo nuclei is presented and extended to nuclei having more than one halo nucleons. The reaction mechanism is treated with and without taking account of the nai-sfcate interaction. The wave function of removal halo nucleons in the continuum state is modified by imposing an orthogonal condition to the bound state. An analytical expression of the longitudinal momentum distribution of the fragment is derived when the bound state wave function of halo nucleons is taken as a Gaussian-type function. This is useful in the further investigation on the structure of halo nuclei.
