The bear watches the dragon. The Russian debate on China. OSW Point of View Number 31, February 2013

Most participants in the Russian public debate seem to agree in their evaluation of the present condition of Russian-Chinese relations. There is awareness of increasing inequality between these two powers and Russia’s weakening position as compared to China.Those who share the optimistic view see co-operation with China as an opportunity for the Russian economy and a key element of Russia’s multi-directional foreign policy, an opportunity for Russia to avoid unilateral dependence on the West. The pessimists view the deepening co-operation with China through the prism of threats resulting from the increasing imbalance in bilateral relations. The greatest source of concern is the model of economic relations, which is often referred to as neo-colonial, where Russia’s role is reduced to that of a supplier of raw materials to China. The possible consequences are evaluated in different ways, ranging from the political subordination of Russian interests the Chinese ones to real loss of control over the Russian Far East. Those who share such views believe that Moscow should slow down its rapprochement with China and search for other partners in Eastern Asia, relations with whom could counterbalance the Chinese influence.

The Eurasian Economic Union – more political, less economic. OSW Commentary Number 157/20.01.2015

The Eurasian Economic Union is undoubtedly the most comprehensive form of economic integration of the post-Soviet countries since the break-up of the Soviet Union. However, the way in which the integration process has been unfolding, as well as Russia’s aggressive policy over the last year, are indications that the EEU has become primarily a political project, and the importance of its economic aspects has eroded. This has triggered a change in the way Kazakhstan and Belarus treat the EEU. Initially, the two countries viewed integration as an opportunity for the development of genuine economic co-operation. However, Russia’s annexation of Crimea and the conflict in Ukraine have revealed the real significance of the EEU project – as a tool to reinforce Russian influence in the post-Soviet area and isolate the post-Soviet countries from the West and China. While the Kremlin presents the EEU as the Eurasian equivalent of the European Union, the project is in reality an imitation of integration. The reasons for this include the nature of the political systems in the participating countries, which are authoritarian, prone to instrumentalise law, and affected by systemic corruption; the aggressive policy that Russia has been pursuing over the last year; and Russia’s dominant role in defining the shape of the EEU. The EEU appears to be based on forceful integration, and is becoming less and less economically attractive for its member countries other than Russia. Moreover, it is clearly assuming a political dimension that those other member countries perceive as dangerous. For these reasons, its functioning will depend on the power and position of Russia. In the longer term it is likely that the other member states will try to ‘sham’ and delay closer integration within the EEU. This means that if Russia becomes politically and economically weaker, the EEU may evolve into an increasingly dysfunctional organisation – a development that will be reinforced by the low standards of legal culture in its member states and their reluctance to integrate. Should Russia’s power increase, the EEU will become an effective instrument of Russian dominance in the area of the former USSR.

A ship run aground Deepening problems in the Ukrainian economy. OSW Commentary Number 173, 16 June 2015

The drop in Ukraine’s GDP by nearly 18% in the first three months of 2015 (versus the corresponding period in 2014) has confirmed the decline of the country’s economy. Over the last 14 months, the Ukrainian currency was subject to an almost threefold devaluation against the US dollar, and in April 2015 the inflation rate was 61% (year-on-year), which exacerbated the impoverishment of the general public and weakened domestic demand. The main reason behind the crisis has been the destruction of heavy industry and infrastructure in the war-torn Donbas region, over which Kyiv no longer has control, as well as a sharp decline in foreign trade (by 24% in 2014 and by 34% in the first quarter of 2015), recorded primarily in trading volume with Ukraine’s major trade partner, i.e. Russia (a drop of 43%). The conflict has also had a negative impact on the production figures for the two key sectors of the Ukrainian economy: agriculture and metallurgy, which account for approximately 50% of Ukrainian exports. The government’s response to the crisis has primarily been a reduction in the costs of financing the Donbas and an increase in the financial burden placed on the citizens and companies of Ukraine. No radical reforms which would encompass the entire system, including anti-corruption reforms, have been carried out to stop the embezzlement of state funds and to facilitate business activity. The reasons for not initiating reforms have included the lack of will to launch them, Ukraine’s traditionally slow pace of bureaucratic action and growing dissonance among the parties making up the parliamentary coalition. The few positive changes, including marketisation of energy prices and sustaining budgetary discipline (in the first quarter of 2015, budgetary revenues grew by 25%, though partly as a result of currency devaluation), are being carried out under pressure from the International Monetary Fund, which is making the payment of further loan instalments to the tune of US$ 17.5 billion conditional upon reforms. Despite assistance granted by Western institutional donors and by individual states, the risk of Ukraine going bankrupt remains real. The issue of restructuring foreign debt worth US$ 15 billion has not been resolved, as foreign creditors who hold Ukrainian bonds have not consented to any partial cancellation of the debt. Whether Ukraine’s public finances can be stabilised will depend mainly on the situation in the east of the country and on the possible renewal of military action. It seems that the only way to rescue Ukraine’s public finances from deteriorating further is to continue to ‘freeze’ the conflict, to gradually implement wide-ranging reforms and to reach a consensus in negotiations with lenders.

Real-time PCR in the microbiology laboratory

Use of PCR in the field of molecular diagnostics has increased to the point where it is now accepted as the standard method for detecting nucleic acids from a number of sample and microbial types. However, conventional PCR was already an essential tool in the research laboratory. Real-time PCR has catalysed wider acceptance of PCR because it is more rapid, sensitive and reproducible, while the risk of carryover contamination is minimised. There is an increasing number of chemistries which are used to detect PCR products as they accumulate within a closed reaction vessel during real-time PCR. These include the non-specific DNA-binding fluorophores and the specific, fluorophore-labelled oligonucleotide probes, some of which will be discussed in detail. It is not only the technology that has changed with the introduction of real-time PCR. Accompanying changes have occurred in the traditional terminology of PCR, and these changes will be highlighted as they occur. Factors that have restricted the development of multiplex real-time PCR, as well as the role of real-time PCR in the quantitation and genotyping of the microbial causes of infectious disease, will also be discussed. Because the amplification hardware and the fluorogenic detection chemistries have evolved rapidly, this review aims to update the scientist on the current state of the art. Additionally, the advantages, limitations and general background of real-time PCR technology will be reviewed in the context of the microbiology laboratory.

A general-purpose tunable landscape generator

The research literature on metalieuristic and evolutionary computation has proposed a large number of algorithms for the solution of challenging real-world optimization problems. It is often not possible to study theoretically the performance of these algorithms unless significant assumptions are made on either the algorithm itself or the problems to which it is applied, or both. As a consequence, metalieuristics are typically evaluated empirically using a set of test problems. Unfortunately, relatively little attention has been given to the development of methodologies and tools for the large-scale empirical evaluation and/or comparison of metaheuristics. In this paper, we propose a landscape (test-problem) generator that can be used to generate optimization problem instances for continuous, bound-constrained optimization problems. The landscape generator is parameterized by a small number of parameters, and the values of these parameters have a direct and intuitive interpretation in terms of the geometric features of the landscapes that they produce. An experimental space is defined over algorithms and problems, via a tuple of parameters for any specified algorithm and problem class (here determined by the landscape generator). An experiment is then clearly specified as a point in this space, in a way that is analogous to other areas of experimental algorithmics, and more generally in experimental design. Experimental results are presented, demonstrating the use of the landscape generator. In particular, we analyze some simple, continuous estimation of distribution algorithms, and gain new insights into the behavior of these algorithms using the landscape generator.

Rapid quantification of hepatitis B virus DNA by real-time PCR using efficient TaqMan probe and extraction of virus DNA

Aim: To rapidly quantify hepatitis B virus (HBV) DNA by real-time PCR using efficient TaqMan probe and extraction methods of virus DNA. Methods: Three standards were prepared by cloning PCR products which targeted S, C and X region of HBV genome into pGEM-T vector respectively. A pair of primers and matched TaqMan probe were selected by comparing the copy number and the Ct values of HBV serum samples derived from the three different standard curves using certain serum DNA. Then the efficiency of six HBV DNA extraction methods including guanidinium isothiocyanate, proteinase K, NaI, NaOH lysis, alkaline lysis and simple boiling was analyzed in sample A, B and C by real-time PCR. Meanwhile, 8 clinical HBV serum samples were quantified. Results: The copy number of the same HBV serum sample originated from the standard curve of S, C and X regions was 5.7 × 104/ mL, 6.3 × 102/mL and 1.6 × 103/mL respectively. The relative Ct value was 26.6, 31.8 and 29.5 respectively. Therefore, primers and matched probe from S region were chosen for further optimization of six extraction methods. The copy number of HBV serum samples A, B and C was 3.49 × 109/mL, 2.08 × 106/mL and 4.40 × 107/mL respectively, the relative Ct value was 19.9, 30 and 26.2 in the method of NaOH lysis, which was the efficientest among six methods. Simple boiling showed a slightly lower efficiency than NaOH lysis. Guanidinium isothiocyanate, proteinase K and NaI displayed that the copy number of HBV serum sample A, B and C was around 105/ mL, meanwhile the Ct value was about 30. Alkaline failed to quantify the copy number of three HBV serum samples, Standard deviation (SD) and coefficient variation (CV) were very low in all 8 clinical HBV serum samples, showing that quantification of HBV DNA in triplicate was reliable and accurate. Conclusion: Real-time PCR based on optimized primers and TaqMan probe from S region in combination with NaOH lysis is a simple, rapid and accurate method for quantification of HBV serum DNA. © 2006 The WJG Press.

Real-Time Gene-Expression Extraction with Fast Classification (FC) Networks

Fast Classification (FC) networks were inspired by a biologically plausible mechanism for short term memory where learning occurs instantaneously. Both weights and the topology for an FC network are mapped directly from the training samples by using a prescriptive training scheme. Only two presentations of the training data are required to train an FC network. Compared with iterative learning algorithms such as Back-propagation (which may require many hundreds of presentations of the training data), the training of FC networks is extremely fast and learning convergence is always guaranteed. Thus FC networks may be suitable for applications where real-time classification is needed. In this paper, the FC networks are applied for the real-time extraction of gene expressions for Chlamydia microarray data. Both the classification performance and learning time of the FC networks are compared with the Multi-Layer Proceptron (MLP) networks and support-vector-machines (SVM) in the same classification task. The FC networks are shown to have extremely fast learning time and comparable classification accuracy.

Off-line signature verification and forgery detection system based on fuzzy modeling

This paper presents an innovative approach for signature verification and forgery detection based on fuzzy modeling. The signature image is binarized and resized to a fixed size window and is then thinned. The thinned image is then partitioned into a fixed number of eight sub-images called boxes. This partition is done using the horizontal density approximation approach. Each sub-image is then further resized and again partitioned into twelve further sub-images using the uniform partitioning approach. The features of consideration are normalized vector angle (α) from each box. Each feature extracted from sample signatures gives rise to a fuzzy set. Since the choice of a proper fuzzification function is crucial for verification, we have devised a new fuzzification function with structural parameters, which is able to adapt to the variations in fuzzy sets. This function is employed to develop a complete forgery detection and verification system.

Fuzzy modeling based recognition of multi-font numerals

In this paper, we present a new scheme for off-line recognition of multi-font numerals using the Takagi-Sugeno (TS) model. In this scheme, the binary image of a character is partitioned into a fixed number of sub-images called boxes. The features consist of normalized vector distances (gamma) from each box. Each feature extracted from different fonts gives rise to a fuzzy set. However, when we have a small number of fonts as in the case of multi-font numerals, the choice of a proper fuzzification function is crucial. Hence, we have devised a new fuzzification function involving parameters, which take account of the variations in the fuzzy sets. The new fuzzification function is employed in the TS model for the recognition of multi-font numerals.

DO VIRTUAL AO REAL: COMUNICAÇÃO, SEXO E INTERNET

Este trabalho é um estudo exploratório sobre o Ambiente Comunicacional Internet que investiga tanto a possibilidade da influência de suas ferramentas de interação/comunicação sobre o comportamento sexual e de risco quanto o desenvolvimento de comportamento compulsivo no uso destas ferramentas na busca de parceiros sexuais. A metodologia adotada é, além da pesquisa bibliográfica, a da pesquisa exploratória, um levantamento e análise de dados quantitativos e pode ser considerada como pertencente ao paradigma tradicional empírico, pois a coleta de dados foi baseada em respostas a questionários semi-estruturados, aplicados a um grupo de informação composto por 428 estudantes universitários dos cursos ligados à área de Computação e Informática de uma instituição particular de Ensino Superior do município de São Paulo SP, Brasil. Para isso, obedece à Resolução do Conselho Nacional de Saúde CNS 196/96 e conta com o TCLE. Os resultados indicam que as práticas sexuais, a exposição a DST e vírus HIV e, particularmente, a tendência ao desenvolvimento do Transtorno de Adicção à Internet se distinguem de modo irrefutável. Os participantes que alegaram buscar parceiros sexuais reais na Internet são diretos nos seus objetivos, pois quando encontram esse parceiro concretizam o ato sexual, em ambientes impessoais, como por exemplo, o motel, e muitas vezes de modo arriscado no que toca à prevenção e à segurança no contato com outro. Destaca-se, ainda, que a compulsão não é reconhecida pelo grupo e que a procura de parceiros por intermédio das mídias digitais, para esse grupo, não está relacionada a itens negativos quanto a sua qualidade de vida o que suscita o estudo e a discussão mais aprofundada sobre a interação comunicação, sexo e Internet .(AU)
