Cell Transformation by RNA Viruses: An Overview
Authors: Fan Hung
Published: June 2011

Studies of oncogenic viruses have made seminal contributions to the molecular biology of cancer. Key discoveries include the identification of viral oncogenes and cellular proto-oncogenes, elucidation of signal transduction pathways, and identification of tumor suppressor genes. The origins of cancer virology began almost exactly one hundred years ago with the discovery of avian sarcoma and acute leukemia viruses—RNA-containing viruses of the retrovirus family. The study of animal cancer viruses accelerated beginning in the late 1960s and early 1970s, with the discovery of DNA viruses that could transform cells in culture, and the development of quantitative assays for transformation by DNA and RNA-containing tumor viruses. The discovery of reverse transcriptase in retroviruses in 1970 also greatly accelerated research on these viruses. Indeed RNA and DNA tumor viruses led the way in cancer molecular biology during this era before molecular cloning. It was possible to physically purify virus particles and generate specific hybridization probes for viral DNA and RNA at a time when it was not possible to analyze cellular genes in the same manner.

Managing Water Supply through Joint Regional Municipal Authorities in Finland: Two Comparative Cases
Authors: Stenroos Marko , Katko Tapio S.
Published: June 2011

The aim of this paper is to analyze two Finnish Joint Regional Authorities for Water Supply—namely the Raisio-Naantali Joint Municipal Authority for Water Supply (established in 1957) and the Tuusula Region Joint Municipal Authority for Water Supply (established in 1967)—for assessing the development of supra-municipal water governance. The above two cases make it possible to analyze and assess water policies in settings where the owners are groups of municipalities. The analysis is based on two separately conducted case studies. The study data consist of several types of materials: Annual reports, local government documents, etc. The conducted interviews were semi-structured with some themes defined beforehand. The studies describe two authorities in the context of historical development and as a part of local development.

Résumé

Découvert en 1930, le site de Kitzan, à quelques kilomètres de Tétouan, n'avait fait jusqu'à présent l'objet d'aucune publication détaillée. On y a recueilli surtout de la céramique, de la Campanienne Β (et des imitations), mais aussi un vase du 8e ou 7e s. av. J C. Ce dernier, exemplaire unique, serait le plus ancien témoignage de la présence punique dans la vallée du Rio Martin. Ce petit habitat aurait été détruit au 1er s. av. J.C. pour des raisons qui ne sont pas connues avec précision.

Imvs: a tool for the macroeconomic analysis

of sectoral policies,

by Dominique Bureau and Béatrice Laury.

Macroeconomic considerations such as employment or the trade balance must always be taken into account when analysing public projects and sectoral policies. However, mersly quantifying the corresponding effects is a difficult process which the Imvs is designed to clarify at a lower cost than the development of specific models. First of all, the operating principles of this type of tool are described, based on the study of a theoretical case which illustrates the possibilities of using the elementary multipliers of a traditional macroeconomic model for this purpose. A summary application to the analysis of export aids is then presented to illustrate the approach the user should adopt.

The Impact of Public Debt on Some French Macroeconomic Variables,

by Claude Deniau, Georges Fiori, Alexandre Mathis.

Granger's statistical methods based on causality tests are used in the examination of relationships between public debt and other significant macroeconomic aggregates. This study brings out that the increase in public debt has little effect on the domestic interest rate or on money supply; conversely, a significant though indirect effect is shown on the external current account balance.

von Patrick Artus, Eric Bleuze, Philippe Ducos.

Nach einem Verweis auf die theoretischen Modelle, die sich auf die Gestaltung der Zinssätze hinsichtlich ihrer Fnstigkeit und auf das Reaktionsverhalten der Behörden beziehen, wird die Bildung der kurz — und langfristigen Zinssätze in Frankreich und in der BRD untersucht. Im einzelnen werden der Einf luss der amenkanischen Sätze auf die Zinssätze in Europa geprüft, der Beeinflussungsgrad zwischen französischen und deutschen Sätzen sowie die Zielsetzungen und der Handlungsspielraum der Zentralbanken, wenn sie kurzfristige Sätze festlegen. Gab es in letzter Zeit in zunehmendem Masse Zusammenhänge zwischen langfristigen Sätzen oder erstarrte im Gegenteil das befristete Verhältnis zwischen kurz — und langfristigen Sätzen ?

Comparison between the Level of French and German (FRG) Mandatory Social Contributions and Social Costs,

by Magali Demotes-Mainard.

Oecd data, customarily used for international comparisons, reveal a significant gap between the rates of taxes and social security contributions in France and in Germany, basically due to the burden of social contributions in France. However, it would be premature to conclude that the cost of social protection is greater in France than it is on the other bank of the Rhine: once the institutional difference between the two countries (primarily regarding the budgetary financing of certain benefits and the prominence of private insurance), the financial ressources allocated to social protection are virtually the same in France as in the FRG.

A brief defense of panel data,

by Brigitte Dormont.

This article seeks to illustrate the contribution of panel data to production econometrics and the advantages and difficulties involved in their use. The examples clearly illustrate the uncertainties confronting conventional macro-econometrics: labor yields in employment functions, comparative employment flexibility in France and West Germany, measurement of capital-labor substitutability, the endogenization of technical progress, the role of profits in investment behavior, and the assessment of disequilibrium phenomena at the disaggregated level.

Interpretacion de la deseleracion de la productividad industrial en la epoca de la segunda crisis petrolera,

por Gilbert Cette, Daniel Szpiro.

El presente estudio propone, partiendo de una muestra de aproxirnadamente 3 200 empresas industrials, una descripción de los factures explicativos delcrecimiento y de la productividad en la industria en el perîodo 1974-1984 e intenta interpretar, mediante una función de producción de Solow, la deseleración sensible del crecimiento observado en 1979-1980. Dicha deseleración se encuentra ligada principalmente a una menor progresión del volumen de los factures de producción en los bienes intermedios y a una debilitación del avance técnico no incorporado en los bienes de equipo. El avance técnico incorporado no parece haber experimentado dismunición y el ligero envejecimiento de los equipos de la industria manufacturera sólo tuvo poco impacto

Las relaciones entre productores y distribuidores : un enfoque empirico,

por Alain Chappert y François Ecalle.

Las relaciones entre el gran comercio y sus proveedores han experimentado una crisis en 1984 y 1985. La creación de supercentrales de compra ha incrementado, en efecto, los puntos afavor de los distribuidores trente a los productores. Este artículo tiene por objeto ver este conflicto dentro de una perspectiva histórica : antes de enfrentarse con estos proveedores, el gran comercio mantenía relaciones difîciles con el comercio tradicional y la industria. Sin embargo, los indicios de acontecimientos de 1984 y 1985 son poco perceptibles. No es posible aislar los inconvenientes que han tenido que soportar productores con fuerte poder de mercado, mientras que las comparaciones internacionales muestran que la potencia de las industrias agrícolas y alimentarias y de la gran distribución no son antinómicas.

Published: June 2011

The authors examine the impact of corporate philanthropic activities on their economic performance. Corporate philanthropy is defined as a component of corporate social responsibility which opens new opportunities for business relationship with stakeholders and is contributing to promotion of corporate social involvement and to diffusion of the social responsibility principles implementation. With an emphasis on the positive impact of philanthropic activities on corporate economic performance, the benefits of corporate philanthropic activities to future revenue growth, characterized by improvement in corporate image, reputation development, business growth and customer loyalty are considered, as well as other economic benefits such as improved recruitment, the growth of innovation, value of share growth, sales growth, the increase in employee morale and productivity, the rise of customer curiosity to know companies which carry out philanthropic actions. This paper reviews the corporate philanthropic activities in Lithuania in recent years and focuses on the relationship between philanthropic activities of corporation “TEO LT” and its financial performance improvements. Having examined the issue of the impact of corporate philanthropic activities on its economic performance, the authors found that corporate philanthropic activities have a positive impact not only on corporate financial indicators related to future revenue growth, but also on other economic indicators, as well as on the relationship with all stakeholders.
SMOOTHING TECHNIQUES FOR MARKET FLUCTUATION SIGNALS
Authors: Dzikevičius Audrius , Šaranda Svetlana
Published: June 2011

The financial crisis of 2008–2009 caused lots of discussions between Academia and as a result researches on financial crisis and bubble prediction possibilities appeared. Academia shows its growing interest in the issue during the last decade. The majority of researches made are based on different forms of forecast used. Some of previous studies claim that the trend of the stock market can be forecasted using moving average method. After the finance market crashed, a need to forecast further possible bubbles arises. As the economics of the Baltic States is very sensitive to such bubbles it is very important to forecast preliminary the trends of the finance markets ant to plan the right actions in order to temper such bubble influence on the national economics. Although economic theory is opposite to the technical analysis theory which is the main tool for traders in stock markets it is used widely. This paper examines whether a proper technical analysis rule such as Exponential Moving Average (EMA) has a predictive power on stock markets in the Baltic States. The method is applied to OMX Baltic Benchmark Index and industrial indexes as they are more or less sensitive to the main index fluctuations. The results were compared using systematic error (mean square error, the mean absolute deviation, mean forecast error, the mean absolute percentage error) and tracking signal evaluation, CAPM method and appropriate period of EMA finding for each market forecast. A graphical analysis was used in order to determine whether EMA can forecast the main trends of the stock market fluctuations. The conclusions made during the research suggest new research issues and new hypotheses for its further testing.
PORTUGUESE STOCK MARKET: A LONG-MEMORY PROCESS?
Authors: Rege Sameer , Martín Samuel Gil
Published: June 2011

This paper gives a basic overview of the various attempts at modelling stochastic processes for stock markets with a specific application to the Portuguese stock market data. Long-memory dependence in the stock prices would completely alter the data generation process and econometric models not considering the long-range dependence would exhibit poor forecasting abilities. The Hurst exponent is used to identify the presence of long-memory or fractal behaviour of the data generation process for the daily returns to ascertain if the process follows a fractional brownian motion. Detrended fluctuation analysis (DFA) using linear and quadratic trends and the Geweke Porter-Hudak methods are applied to detect the presence of long-memory or persistence. We find that the daily returns exhibit a small amount of long memory and that the quadratic trend used in the DFA overestimates the value of the Hurst exponent. These findings are corroborated by the use of the Geweke Porter-Hudak method wherein the Hurst exponent is close to the DFA using the linear trend.

Background

Little is known in HIV-2 infection about the kinetics of disappearance of raltegravir (RAL)-resistant virus after RAL withdrawal.

Methods

RAL was interrupted in four highly antiretroviral- experienced HIV-2-infected patients exhibiting a virological failure when receiving RAL. Integrase gene was sequenced from plasma samples collected at the time of RAL failure and at further time points following RAL withdrawal.

Results

At the time of RAL withdrawal, virus exhibited different integrase resistance pathways: G140S/Q148R, E92Q/N155H, T97A/N155H and T97A/Y143C. In patient 1, the G140S/Q148R double-mutant was still detected at month (M)7 and at M11 after stopping RAL, but was no longer detected at M15. Regarding patient 2, the double- mutant E92Q/N155H was still present at M2 and M8 after stopping RAL, and was no longer detected at M12. In patient 3, RAL-resistant virus with T97A/N155H mutations were still present 1 month after stopping RAL, and were no longer detected at M14. Regarding patient 4, the mutant T97A/Y143C was still detected at M1 and M3 following RAL withdrawal. At M18 after RAL stop, integrase genotypic pattern evolved to T97A/Y143G.

Conclusions

Persistence of HIV-2 RAL-resistant mutants was observed in all the key genetic RAL resistance pathways. These findings have clinical implications especially in HIV-2-infected patients for whom therapeutic arsenal is limited compared to HIV-1, since the persistence of resistant mutants might compromise the possible efficacy of upcoming second-generation integrase inhibitors.

Alors que Freud et sa mouvance traitent de « pulsion d’emprise » dans la perspective strictement psychanalytique, Robert Pagès, sans la récuser, met la notion des processus d’emprise au centre de la psychologie sociale ; il produit articles et colloques sur ce thème. Sans éviter une certaine exubérance lexicale, il confère à l’emprise un sens et un champ extensif et compréhensif très stimulants. Il mène parallèlement, des expérimentations, dont plusieurs résultats convergent avec les acquis cliniques, notamment sur l’impact de la formation relationnelle.

Cet article propose d’analyser les deux révolutions tunisienne et égyptienne selon deux points de vue : le premier est celui des mécanismes d’emprise à l’œuvre entre dirigeants et citoyens dans ces deux pays et un peu partout dans les pays anciennement colonisés. Le second est celui des mécanismes d’emprise qui ont lieu dans le rapport de l’Occident à ces pays. Pour le premier angle, nous développons le concept d’emprise du désir et, pour le second, celui de désir d’emprise. Nous terminons enfin par une mise en exergue des conditions et mécanismes d’émancipation et de dégagement de l’emprise.
Postmodernité et nouvelles formes du narcissisme chez le bébé
Authors: Mellier Denis
Published: June 2011

L’auteur développe l’hypothèse que l’approfondissement de la modernité à un impact sur les représentations du « bébé parfait ». Au niveau culturel, la mise en évidence des compétences du bébé aboutit à l’individualiser de plus en plus tôt. Tandis que le matériel éducatif et de puériculture transmet cette influence, la pression sur la naissance, sa médicalisation et son entrée dans le champ marchand s’accompagnent d’une dé-ritualisation du temps du nourrisson. Les parents se trouvent paradoxalement plus seuls devant leur bébé. Ce défaut d’étayage social a des conséquences sur la différenciation des enveloppes psychiques tout au long de la petite enfance. Deux exemples cliniques illustrent cette thèse.

A new quadrilateral arrangements for landmark Multi Dimensional Scaling (LMDS) is proposed in this paper. The proposed strategy for choosing the landmark points improved the accuracy which was the main flaw of LMDS. After employing this arrangement, the improved quadrilateral landmarks MDS (QLMDS) preserves the computational efficiency of LMDS and uses quadrilateral arrangement of landmark points to obtain a higher accuracy. To compare the accuracy and computational efficiency of QLMDS with classical Multi Dimensional Scaling (CMDS) and then the accuracy of QLMDS with LMDS, several simulations are presented. The results, apparently, show that QLMDS is as fast as LMDS, but with a higher accuracy which makes it a better choice than CMDS and LMDS.

Published: June 2011

The circuit that a high-voltage pulse is sharpened by an opening switch and a closing switch is designed. The electric exploding wire switch (EEOS) is adopted as the opening switch to steepen pulse primarily. When the EEOS explodes, the voltage passes through the gas switch which is used as the closing switch， and then is sharpened to high-voltage pulse on the terminal load. This high-voltage and high-current circuit is simulated by steps with the software PSPICE. The experimental results show that the rising time of the pulse steepened twice is nearly 1ns, and the peak voltage is greater than 200kV on condition that the preliminary voltage is 35kV. The results obtained from the simulation and the experiment are identical on the whole. As a result, this circuit has great prospects in the pulse mediation system.

Simply Level Recalculation Using Statistical Approach
Authors: Huang Shih Fang , Chen Chun Sung , Dzeng Ren Jye
Published: June 2011

A railway is a strip-shaped corridor usually divided into multiple sections that are constructed separately. Associated construction contracts must consider scheduling. Because a railway is a continual linear structure, high-precision level surveys are needed for rail sections to connect smoothly. However, the different phases and sections of construction require multiple-level surveys, which often lead to bias in the benchmarks. Since the railway is a continuous alignment, and an inconsistent elevation system affects the civil work and subsequent track laying. This study therefore used a statistical method to eliminate inconsistencies in benchmarks. Statistics are widely used in engineering and in daily life, to solve decision making problems involving uncertainties. This study used the expected value of closing error between benchmarks as an index for recalculating level, and used the standard error of expected value as the accuracy index. Application of the proposed method using measurement data for a Taipei underground project of the Taiwan Railway Administration showed that it eliminates bias in benchmarks and provides the required accuracy for closure between adjacent points.

Published: June 2011

Geometric constraints have an essential significance for point correspondence in computer vision systems. Traditional epipolar constraint in bi-ocular system faces two main problems: threshold-setting and corresponding ambiguities. This paper describes a collinear epipolar plane model and proposes a novel criterion for bi-ocular corresponding which allows setting a uniform threshold. Furthermore, it proposes the concept tri-correspondence units, proves their specificity against ambiguities, and discusses the merging of them.

Published: June 2011

Precise extraction of facial feature points is fundamental to a variety of applications including face processing and human-machine interface. In this paper, a novel method of extracting facial feature points for profile faces is presented. This program is mainly based on a 3D rotation model of head and Active Shape Model (ASM). First we transform a profile face to a corresponding frontal face. Then, we implement the ASM program on the frontal face image. According to the relation between the profile face and frontal face, the final position of feature points on the profile face is obtained. We take limited facial feature points to do experiments and results show this kind of method is pretty effective.

Authors: Xue Guang Da , Hu Li Li , Wang Da Jin
Published: June 2011

In this paper, a novel frequency synchronization algorithm for a new modulation scheme named time domain and frequency domain united orthogonal frequency division multiplexing (TFU-OFDM) is introduced. The frequency synchronization method has two-steps, which joints time and frequency domain estimation based on PN sequences and pilots. We utilize the PN sequences as guard intervals in time domain to achieve the first-step estimation and the second-step is realized by the pilots in data blocks in frequency domain. The simulation results and analysis show that the proposed frequency synchronization method could achieve fast and reliable synchronization and sufficient precision, and provides excellent performance for TFU-OFDM systems.

Authors: Chen Kuen Suan , Wang Ching Hsin , Chang Tsang Chuan
Published: June 2011

Consumer electronic products have become an indispensable part of living for people with the development of information technologies. Crystal oscillator, CXO, a frequency controlling component, which is needed by communication-related industries, is widely used in expensive electronic products like mobile phones, notebook computers and GPS for its outstanding features of stability in temperature and low wearing. In CXO products, wires of ill quality are very likely to lead to ill contact between signal connectors and gold wires on IC or broken wires, which would cause the whole IC-packaged product unable to work normally. This article, thus, will develop a model of assessing and testing process capabilities with process capability index,Cpl, specifically for the larger-the-better quality characteristic of wire process. The article will also provide the assessment procedure, whereby the industry can effectively evaluate whether the process capabilities of their products meet the benchmarks they are supposed to.
An Algorithm of Constraint Frequent Neighboring Class Set Mining Based on Filling Class Set
Authors: Tu Cheng Sheng
Published: June 2011

Since the algorithms of constraint frequent neighboring class set mining based on Apriori is unsuitable for mining any length constraint frequent neighboring class set and has some redundancy computing, this paper proposes an algorithm of constraint frequent neighboring class set mining based on filling class set, which may efficiently extract any length constraint frequent neighboring class set from large spatial database. The algorithm uses binary conversion to turn neighboring class set into integer, and regards these integers as mining spatial database, and it uses double search strategy to generate constraint frequent neighboring class set, namely, one is that the algorithm uses two k-constraint frequent neighboring class sets to connect (k+1)-candidate constraint frequent neighboring class set, the other is that it also uses filling virtual class set of (k+1)-candidate constraint frequent neighboring class set to generate another candidate. In whole mining course the algorithm need only scan database once. The experimental result indicates that the algorithm is more efficient than the constraint frequent neighboring class set mining algorithm based on Apriori when mining any length constraint frequent neighboring class set.

Published: June 2011

A dynamic distributed algorithm (DDA) with a look-up dynamic table instead of ROM was put forward based on the theory of signed distributed algorithm, in order to improve processing speed and flexibility of product sum on FPGA. Since the DDA occupies few hardware resources, performs fast operation and realizes programmable coefficient, the limitation of digital signal processing speed on fixed data bus width and sequential operation was avoided by using the algorithm. At the same time, an effective solution to realizing coefficient programmable FIR filter was presented.
