Spectrum analysis on Mellin Ttransform and fractional Mellin transform

The differences between Mellin transform and Fourier transform are compared from the aspect of spectrum. Some properties of Mellin transform and fractional Mellin transform are generalized. The period of fractional Mellin transform is also investigated. Comparing with Parseval theorem of Fourier transform, a similar theorem of Mellin transform is formulated. In addition, the scale invariance property of Mellin transform has been extended.
The Role of Institutional Entrepreneurship in Standard Wars: The case of Blu-ray Disc

The study is to use institutional entrepreneurship perspective to complement the functionalist’s viewpoint to understand the process underlying collective action in a mature eco-system and how institutional entrepreneurs manage critical stakeholder relations, collective action and discursive activities in technical standard change processes. The standard war of Sony Blu-ray Disc vs. Toshiba HD DVD is used as a critical and intrinsic case. The functionalist’s viewpoints have paid much attentions to the numbers of customers adopting new technologies, and etc. By means of institutional entrepreneurship perspective, it claims that it does not matter about the number and amount, but it does matter about how focal firms make the markets believe that they have the abilities to win standard wars. The study further claims that the variables studied in functionalist’s viewpoint also have the meanings of institutional entrepreneurship perspective. Moreover, the BD and HD DVD standards are incremental innovations in a mature field where there are many things are settled down. Focal firms can easily forecast the expectations of the dominant institutional logics. The study contributes that institutional entrepreneurship perspective still provides the process insight to complement the functionalist’s viewpoint. This perspective can be applied in emerging field, where it is no dominant logics and the innovations are likely to be radical. The BD case represents a critical case. It can makes possible naturalistic generalization to other similar contexts. Eisenhardt’s principles are used to build theory from the case study. I borrowed techniques of open coding to analyze the data. The findings show that collective action (including critical stakeholder management and structuring collaboration capabilities) and discursive activities are the central features of institutional entrepreneurship. They have mutual relationship with the institutional entrepreneur’s resources (power and legitimacy). Furthermore, good collective action and discursive activities can lead to network effects and product performance.
Automatic Image Annotation of News Images with Large Vocabularies and Low Quality Training Data

A traditional approach to retrieving images is to manually annotate the image with textual keywords and then retrieve images using these keywords. Manual annotation is expensive and recently a few approaches have been proposed for automatically annotating images. These techniques usually learn a statistical model using a training set of images annotated with keywords and use this model to automatically annotate test images. While promising, these techniques have generally been tested on a few thousand images, with vocabularies of a few hundred words or less and using relatively high quality training data where the keywords are categories/objects and are directly correlated with the visual data. Here, we investigate the problem of automatically annotating a large dataset of news photographs using low quality training data and a large vocabulary. We use 56,117 images and captions from Yahoo News Photos for our training and test data. The captions in the training portion of this data often contain a great deal of text most of which does not directly describe the image and as labels are, therefore noisy. We use the Normalized Continuous Relevance Models for our annotation and discuss how to speed up the model (by a factor of 10) using a voting technique. An improved distance measure also improves precision. To handle noisy text data and the large vocabulary of 4073 words, we investigate using different kinds of words for training and show that words which describe the content of the picture are significantly more useful for annotating images. Previous work on annotating images has largely dealt with high quality keywords.
Novel Therapeutic Approach for Autism Spectrum Disorder: Focus on SHANK3

SHANK3 is a synaptic scaffolding protein and plays an important role in neuronal development. SHANK3 interacts with various synaptic molecules, including post-synaptic density-95 (PSD-95), homer and GluR1 AMPA receptor. SHANK3 gene is a causable gene of the Phelan- McDermid syndrome (also known as the 22q13.3 deletion syndrome), whose manifestation is global developmental delay and autistic behavior, especially shows severe speech and language deficit. Additionally since cumulative gene analysis in autistic subjects identified several mutations in SHANK3 gene, including deletion and duplication in a particular region, abnormality of SHANK3 gene is thought the be related with the neuropathology of autism spectrum disorder (ASD). We here review the recent findings in regard to the roles of SHANK3 in higher brain functions, molecular-biologic studies of the complex expression of Shank3 transcripts and production of SHANK3 isoforms, and behavioral studies of Shank3-mutant mice, including our recent findings, and discuss a novel therapeutic approach for ASD.
Robustness of localization accuracy for wireless sensor networks under physical attacks

Wireless sensor network localization is an important area that attracted significant research interest. This interest is expected to grow further with the proliferation of wireless sensor network applications. As localization is becoming popular, many attacks on the localization process are also on a rise. These attacks confuse the localization process and cause location estimation errors. Range based methods like received signal strength indication (RSSI) is affected a lot by physical attacks. This paper proposes a solution based on multi frequency multi power antenna to provide robust and accurate localization technique. In addition this paper proposes a grid coloring algorithm to detect the signal hole map in the network which is refer to the attack prone regions in order to take a corrective actions. The simulation results showed improvement in the localization accuracy in the presence of barrier attacks through detecting, filtering and eliminating the effect of these attacks.
Generating Indexing Functions of Regularly Sparse Arrays for Array Compilers

There are many applications involving arrays that contain non-zero components in regular geometric partitions. These include triangular, diagonal, tridiagonal, banded, etc. When computing with this type of arrays, they are usually stored in a packed form and computations are performed with only the non-zero components. This packed form requires an indexing function that maps an index of the array to an index of the packed lexico-graphically stored array. This paper presents a method of describing regular partitions and of automatically generating an indexing function from that description. These methods enable an array compiler to compile array operations on these type of arrays in an eecient manner.
First order relativistic three-body scattering

Relativistic Faddeev equations for three-body scattering at arbitrary energies are formulated in momentum space and in first order in the two-body transition operator directly solved in terms of momentum vectors without employing a partial wave decomposition. Relativistic invariance is incorporated within the framework of Poincar\'e invariant quantum mechanics and presented in some detail. Based on a Malfliet-Tjon-type interaction, observables for elastic and breakup scattering are calculated up to projectile energies of 1 GeV. The influence of kinematic and dynamic relativistic effects on those observables is systematically studied. Approximations to the two-body interaction embedded in the three-particle space are compared to the exact treatment.
Is-Lm with Credit Markets and Inflation Targeting; a Suggestion for Undergraduate Macroeconomics

Economics as introduced to undergraduate students tends to discourage many from pursuing a major. One problem is the unfortunate combination in our macroeconomic models of scientifically necessary rigor and far-reaching abstraction from the real world. Recent contributions have improved real world relevance of the IS-LM model framework by introducing imperfect asset substitutability and inflation targeting as a monetary policy goal. This paper suggests a method for bringing these contributions together within monetary equilibrium that enhances explanatory power and connects these results with related empirical findings. It is shown that the strength of the transmission mechanism from monetary policy to real sector activity depend on overall economic activity.
A mechanism underlying the effects of polyunsaturated fatty acids on breast cancer

Breast cancer is the most frequent cancer in women. Evidence suggests that the polyunsaturated fatty acids (PUFAs), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) affect breast cancer proliferation, differentiation and prognosis. However, the mechanism still remains unclear. In this study, the expression of transient receptor potential canonical (TRPC)3 was detected throughout the cell cytoplasm and at the cell surface of MCF-7 cells. Ca2+ entry was induced in these cells via activated TRPC3 by either the diacylglycerol analogue (OAG) or by intracellular Ca2+ store depletion. TRPC-mediated Ca2+ entry was inhibited by PUFAs including arachidonic acid (AA) and linolenic acid (LA) but not saturated fatty acids. Overexpression of the PUFA degradation enzyme, cyclooxygenase 2 (COX2), enhanced capacitative Ca2+ entry. In addition, inhibition of COX2 reduced [Ca2+]i. Nevertheless, inhibition of TRPC reduced the cell cycle S phase and cell migration, implicating a functional role for TRP-mediated Ca2+ entry in cell proliferation and invasion. Exogenous PUFA as well as a TRPC3 antagonist consistently attenuated breast cancer cell proliferation and migration, suggesting a mechanism in which PUFA restrains the breast cancer partly via its inhibition of TRPC channels. Additionally, our results also suggest that TRPC3 appears as a new mediator of breast cancer cell migration/invasion and represents a potential target for a new class of anticancer agent.
The Influence of Trade with the EU-15 on Wages in the Czech Republic, Hungary, Poland, and Slovakia between 1997 and 2005

I use the STAN database of the OECD and different econometric methods to investigate the effects of exports towards the EU-15 on wages in the Visegrad countries (CEEC-4; Czech Republic, Hungary, Poland, and Slovakia). The results do not allow to draw any definite statements about this effect. While the impact of exports towards the EU-15 on wages in the countries investigated is likely to be negative in the short run (1-2 years), it seems to be positive in the medium and long run, at least for Hungary and Poland. Nevertheless, it is clear that the pattern of the CEEC-4 exports towards the EU-15 does not correspond with the predictions of the Heckscher-Ohlin model. Therefore, also the theorems of Stolper and Samuelson (1941) and concerning the equalization of factor prices, which are based on the Heckscher-Ohlin model, do not seem accurate to describe the underlying forces linking trade with factor prices. I argue that missing regional and related inter-sectoral labor mobility might be a potential factor preventing employees from taking advantage of trade liberalization. To substantiate this suspicion, however, analysis of more disaggregated data is necessary.
The video summary GWAP: summarization of videos based on a social game

Video summarization is a classical problem in multimedia. How can we reduce the size of a video stream to a minium necessary to allow the user for deciding upon relevance of the video. In this paper we present an approach to video summarization that incorporates a social game, a so called game with a purpose. By playing a fun game users contribute to data used to decide which shots of a video are necessary to be included in a summary and which not. The usefulness and feasibility of our approach is shown in an evaluation.
Reakcje kursu walutowego na zmiany poziomu stóp procentowych : analiza zdarzeń dla danych dziennych

W systemie p∏ynnego kursu walutowego, z którym mamy do czynienia w Polsce od 12 kwietnia 2000 r. , wartoÊç krajowej waluty wzgl ́dem walut zagranicznych nie jest ustalana bezpoÊrednio przez w∏adze monetarne. Kurs walutowy kszta∏towany jest na mi ́dzynarodowych rynkach finansowych, gdzie istnieje wiele czynników wp∏ywajàcych na zmiany kursu oraz na jego wartoÊç. Niniejsza praca stanowi prób ́ odpowiedzi na pytanie, czy zmiany stóp procentowych, na przyk∏ad dokonywane przez Rad ́ Polityki Pieni ́ ̋nej (RPP), majà statystycznie istotny wp∏yw na zmiany kursu walutowego w krótkim okresie.

Myco-heterotrophy: when fungi host plants.

BACKGROUND Myco-heterotrophic plants are partly or entirely non-photosynthetic plants that obtain energy and nutrients from fungi. These plants form a symbiosis with arbuscular mycorrhizal, ectomycorrhizal or saprotrophic fungi to meet their nutrient demands. SCOPE This Botanical Briefing summarizes current knowledge about myco-heterotrophy, discusses its controversial aspects and highlights future directions for research. CONCLUSIONS Considerable recent progress has been made in terms of understanding the evolutionary history, germination and nutrition of myco-heterotrophic plants. Myco-heterotrophic plants: (1) are diverse and often ancient lineages that have coevolved with fungi, (2) often demonstrate unusually high specificity towards fungi during germination and maturity, and (3) can either cheat common mycorrhizal networks supported by neighbouring photosynthetic plants to satisfy all or part of their energetic and nutritional needs, or recruit free-living saprotrophic fungi into novel mycorrhizal symbioses. However, several fundamental aspects of myco-heterotrophy remain controversial or unknown, such as symbiotic costs and physiology.
Recent Advances in Research on P2P Networks

As one of the killing applications in NGI, peer-to-peer networks (P2P for short) have rapidly developed in recent years. We survey and catalog the current hot research aspects in P2P networks, compare and review most of the research work in P2P networks, and summarize the research means and their problems
RATE RISK AND CREDIT RISK IN ASSET AND LIABILITY MANAGEMENT Forthcoming in Asset & Liability Management : The Synthesis of New Methodologies Risk Publications , Fall 1998

A recent study by the Federal Reserve [1995] came to the startling conclusion that no interest rate risk variables were statistically significant in predicting bank failures in the United States. The new FIMS monitoring system discussed in this Fed study predicts failure based on 11 key variables collected from the Report of Condition submitted to bank regulators in the United States. Five of the eleven variables are related to the riskiness of commercial lending, and none of the others are related to interest rate risk.
Street-level bureaucrats help clients, even in difficult circumstances

This policy brief presents the main findings of the Marie Curie Project “COPING: Policy implementation in stressful times: Analyzing coping strategies of civil servants”. The project combines insights from public administration and psychology to study how street-level bureaucrats (also termed frontline workers, public professionals or public service workers) cope with stress during public service delivery.
Comment on “ Complete Eulerian mean tracer equation for coarse resolution OGCMs ” by

Dubovikov and Canuto (Dubovikov, M.S. and Canuto, V.M., Complete Eulerian-mean tracer equation for coarse resolution OGCMs. Geophys. Astrophys. Fluid Dyn., 2006, 100, 197–214), after averaging the tracer conservation equation in density coordinates and transforming to height coordinates, concluded that present ocean models are missing important terms in their mean tracer equations. Here we point out some errors made by Dubovikov and Canuto (2006) in their isopycnal averaging procedure. We draw on the temporal-residual-mean (TRM) theory and show that when the isopycnal averaging and coordinate transformation are performed correctly, the tracer equations of present ocean circulation models are recovered. We therefore conclude that present ocean circulation models are not neglecting the leading order terms identified by Dubovikov and Canuto (2006).
The Impact of Demographic Features and Environmental Conditions on Rates of Nursing Burnout

Background: The burnout phenomenon is a complex and multidimensional reality and also a common metaphor for a state of extreme psychophysical exhaustion that is usually related to work. Objectives: The goal of this study was to evaluate nursing burnout in 371 registered nurses at both governmental and private hos- pitals in Shiraz, Iran. PatientsandMethods: This was a cross-sectional study that evaluated nursing burnout using the Maslach Burnout Inventory. Inde- pendent sample T-test and one-way analysis of variance were performed to determine the association between demographic factors, the nurses' working environment, and nurse burnout. Results: The results of this study showed that nurses in internal medicine wards, at sta positions, and on rotating shifts in govern- mental hospitals have a high rate of total burnout (P < 0.05). In contrast, nurses with less than five years of work experience have a high rate of reduced personal accomplishment (P < 0.05). Also, nurses with 6 - 15 years of work experience reported the highest incidence of emotional exhaustion (P < 0.05). Conclusions: Burnout is associated with some specific demographic and environmental features. To reduce and prevent burnout, nursing leadership should focus on personal accomplishments in nurses with little work experience, especially for nurses in inter- nal medicine wards, on rotating shifts, and on sta wards. In addition, policy makers at higher levels should also consider nursing burnout in governmental hospitals.
Composites with nanosilica

There are only a few materials that are promising composites. For decades high-voltage electrical insulation technology used ternary insulation systems; usually based on modified epoxy resins and reconstructed mica. Adding additional components into existing systems, it is possible to influence their properties. However, the disadvantage is an inhomogeneous composite structure that emerges from the very quality of these materials. Inhomogeneous structure material causes defects during operation that increase material and this can limit the life of the entire device. The key to solving this problem is to reduce the dimensions of the individual components, in this case the filler. This paper deals with the study of electrical insulation properties of nanocomposites based on epoxy resin filled with hydrophobic and hydrophilic silica. Nanocomposities were created by using a dissolution method, in which a nanofiller was applied to the melted matrix DGEBA. We made a special mould to cure the samples. To determine the electrical insulating properties the following characteristics were measured: polarization index, volume resistivity, dissipation factor and dielectric strength. The aim of this study is to demonstrate that hydrophobic silica combined with water with little or no hydrogen bonds will have better electrical properties than hydrophobic silica on its own. The results show that the best results were achieved with 1% hydrophobic silica.
T Analysis of Crash Recovery Failure Detection with Quality of Services

We develop a probabilistic model of the behavior of a crash-recovery target, i.e. one which has the ability to recover from the crash state. We show that the fail-free and the crashstop are special cases of the crash-recovery run with mean time to failure (MTTF) approaching to infinity and mean time to recovery (MTTR) approaching to infinity, respectively. We compare the previous work QoS metrics to allow the measurement of the recovery speed, and the definition of the completeness property of a failure detector. Then, the impact of the dependability of the crash-recovery target on the QoS bounds for such a crash-recovery failure detector is analyzed using general dependability metrics, such as MTTF and MTTR, based on an approximate probabilistic model of the two-process failure detection system. Then according to our approximate model, we show how to estimate the failure detector’s parameters to achieve a required QoS, based NFD-S algorithm analytically, and how to execute the configuration procedure of this crash-recovery failure detector. Our analysis indicates that variation in the MTTF and MTTR of the monitored process can have a significant impact on the QoS of our failure detector.
