Considering theoptimistic/pessimistic view of decision makers in the cross-efficiency evaluation

One of the important subjects in the cross-efficiency evaluation that was disregarded in the most of previous studies is that, the decision maker (DM) may have an optimistic or pessimistic attitude towards the both selecting the elements of crossefficiency matrixin the presence of the non-uniqueness of the data envelopment analysis (DEA) optimal weights and the aggregation of efficiencies in each row of the cross-efficiency matrix. To overcome these shortcomings, this paper by obtaining the maximum and minimum cross-efficiency that each of the DMUs can achieve, selects the suitable cross-efficiency members from the view point of the DM based on intermediate value theorem. The study then applies the desirable ordered weighted averaging (OWA) operator weights, which are obtainedfrom the two complementary linear OWA (CLOWA) models, for the aggregation process of the cross-efficiency matrix. Ultimately, the usefulness of the proposed method is demonstrated by using a numerical example.
Cloning of two basic helix-loop-helix transcription factor genes from Tartary buckwheat ( Fagopyrum tataricum ) and their expression under abiotic stress

Basic helix-loop-helix (bHLH) transcription factors are one of the most important transcription factors involved in abiotic stress tolerance in Tartary buckwheat. In this study, we successfully isolated two bHLH transcription factor genes, designated as FtbHLH1 and FtbHLH2, from Tartary buckwheat. Their encoding proteins were found to have a motif to interact with R2R3-MYB at the N-terminus and a typical bHLH motif at the C-terminus. Yeast one-hybrid assay proved that the two bHLH proteins exhibited obvious transcriptional activation activities. The abiotic stresses indicated that FtbHLH1 expression would be mainly affected by drought and UV-B, whereas FtbHLH2 expression would present a sensitive response to cold and UV-B. Additionally, FtbHLH2 showed a more intense response to jasmonic acid treatment than FtbHLH1.
Ecotoxicity of Nanoparticles in Aquatic Environments: A Review Based onMultivariate Statistics of Meta-Data

Evaluation of environmental effects due to exposure to nanoparticles is a still partially unexplored frontier of research, although increasing use of these substances leads to the presumption of a notable increase in their emission in the near future. Current knowledge of possible impacts of nanoparticle emission on aquatic ecosystems (e.g. lagoons, estuaries, marine coasts) is not yet exhaustive in terms of the responses of aquatic species from different trophic levels to exposure to various nanoparticles types (different substances and particle sizes). This paper aims to collect and discuss recent data on ecotoxicological effects observed in aquatic species and to analyse, on a multivariate statistical basis, meta-data collected to evaluate relationships between nanoparticle size and ecotoxicological responses observed in several aquatic species with regard to the most commonly used substances (TiO2, ZnO).

Local entropy patterns in continuous cellular automaton models

The article presents the results of the simulation of a cellular automaton model whose cells assume continuous values. The described experiment examined the behaviour of local entropy and showed the occurrence of its three qualitatively different images with their character resembling Turing patterns. The hypothesis, according to which the behaviour of local entropy might be identified with an image created in a reaction-diffusion process, was presented. Problem The research study concerning the mathematical foundations of creating cultures (Zgrzebnicki, in press-a) considers a continuous cellular automaton model as a hypothetical framework. Although there have been many studies on the properties of discrete cellular automata published so far, the models whose cells assume any values limited only by floating point precision have been much less discussed in scientific works. The research presented herein assumed that the discussed automaton may change values of its cells according to any function transforming the values of neighbours in the neighbourhood of a certain radius, and that this radius and weight of the neighbours' contribution to a cell's change may also be arbitrarily defined for the purposes of a certain experiment. In comparison with discrete automata (Wolfram, 1984), such assumptions imply a much broader class of solutions. The conducted research is aimed at finding an answer to the question whether there are any general regularities or patterns describing the dynamics of the assumed model. Method Let there exist a matrix ! , whose components are called cells. Let there exist a function ", which transforms matrix ! into matrix ! ’ in a way that: $% ′ = "()% * $*, ,) , where $ stands for the cell's value, while % and * mean coordinates, and r means a radius within which the neighbourhood of a certain cell has an influence on its value's transformation. Furthermore, to eliminate the problem of boundary values, let us assume that the boundaries of the matrix are glued together so that topology of the described space is identical with a torus. Figure 1: The value of cells established on the basis of the values of their neighbours located within the radius , = 3. Topology of glued boundaries guarantees continuity of solutions on the edges of the matrix. Finally, let us consider process 0 in which values of all the cells are changed so that a matrix obtained after the change becomes a source matrix for the next step: 0:! → ! 3 → ! 33 → ! 333 → ⋯
Power electronics for renewable energy systems – Status and trends

In the past few decades, the energy paradigms in many countries are experiencing significant change from fossilbased resources to cleaner renewables. It is expected that the scenario of highly penetrated renewables is going to be further enhanced. This requires that the production, distribution and use of the energy to be as technological efficient as possible, and incentives to save energy at the end-user should also be strengthened. In order to realize the transition smoothly and effectively, power conversion systems will continue to play an essential role. Using highly efficient power electronics in generation, transmission/distribution and end-user application, together with advanced controls, can pave the way for renewable energy resources. In view of this, some of the most promising renewable candidates like wind power and photovoltaic, which are becoming a significant part in the electricity production, are explored in this paper. Issues like technology demands, power converter topologies, and control structures are addressed. Some special focuses are also paid on the emerging trends in power electronics development for those systems.
"SPIRITUAL, BUT NOT RELIGIOUS:" THE IMPACT OF PARENTAL DIVORCE ON THE RELIGIOUS AND SPIRITUAL IDENTITIES OF YOUNG ADULTS IN THE UNITED STATES

In recent years, researchers have exhibited considerable interest in the distinctions between "religion " and "spirituality," and in the apparently growing numbers of people in western societies who self-identify as "spiritual but not religious. " However, few studies have systematically examined the antecedents or correlates of these important constructs. Using data on a nationwide (US) sample of 1,500 young adults (ages 18-35) half of whom are children of divorce and the other half of whom were raised in intact, two-parent families, our results underscore the potential importance of parental divorce in giving rise to a "spiritual hut not religious" identity. Specifically, offspring of divorce constitute the majority (62%) of this category in our sample. Even with controls for sociodemographic factors, offspring of divorce are significantly less likely to identify themselves as "religious" but no less inclined to self-identif as "spiritual," as compared with young adults from intact families. Implications of these patterns for the intergenerational transmission of religious faith and other aspects of contemporary American culture are discussed.
Contributions of Plant Taxonomy, Herbarium and Field Germplasm Bank to Conservation of Threatened Plants:Case Studies from the Himalayas and Eastern and Western Ghats

Conservation of biodiversity, a growing concern today, faces multiple challenges. Although ecosystem approach has been recommended as a solution, conservation of threatened species is difficult as they are spread across the ecosystems and are often restricted to microhabitats. In this article, the importance of taxonomy, herbarium and field germplasm bank in conservation of threatened species is discussed. It is concluded that individually each of these measures has important role to play in conservation. They also complement each other in reversing the threat perspective of the species.
Potential Odor Intensity Grid Based UAV Path Planning Algorithm with Particle Swarm Optimization Approach

This paper proposes a potential odor intensity grid based optimization approach for unmanned aerial vehicle (UAV) path planning with particle swarm optimization (PSO) technique. Odor intensity is created to color the area in the searching space with highest probability where candidate particles may locate. A potential grid construction operator is designed for standard PSO based on different levels of odor intensity. The potential grid construction operator generates two potential location grids with highest odor intensity. Then the middle point will be seen as the final position in current particle dimension. The global optimum solution will be solved as the average. In addition, solution boundaries of searching space in each particle dimension are restricted based on properties of threats in the flying field to avoid prematurity. Objective function is redesigned by taking minimum direction angle to destination into account and a sampling method is introduced. A paired samples -test is made and an index called straight line rate (SLR) is used to evaluate the length of planned path. Experiments are made with other three heuristic evolutionary algorithms. The results demonstrate that the proposed method is capable of generating higher quality paths efficiently for UAV than any other tested optimization techniques.
Brazilian Portuguese as a community language: the training journey of a teacher in London

The increase in the number of Brazilian emigrants in the last thirty or so years has led to the development of the teaching of Brazilian Portuguese as a community language abroad. In other words, this type of teaching is new and, consequently, the teachers working in community schools tend to have been trained only to work with monolingual pupils in Brazil. In this article, we reflect on the experience of one of these teachers and who works with intermediate and upper-intermediate pupils aged 11 to 15 in London. The class that caters for this group of learners was initially created with the aim of preparing them to take mainstream examinations, i.e. GCSE and A-levels in Portuguese. In this article, we describe the contextual background for these lessons and contrast it to the teacher’s expectations of teaching in this context. We then consider the few teaching courses available for teachers of Portuguese as a community language in London. Anderson’s (2008) perceived 8-strand professional development needs of community language teachers are used as a framework for analysing the experience of this Brazilian teacher. We acknowledge the positive impact of these courses on teacher knowledge and practices and call for more of these initiatives.
Calcifying invertebrates succeed in a naturally CO 2 -rich coastal habitat but are threatened by high levels of future acidification

Abstract. CO2 emissions are leading to an acidification of the oceans. Predicting marine community vulnerability towards acidification is difficult, as adaptation processes cannot be accounted for in most experimental studies. Naturally CO2 enriched sites thus can serve as valuable proxies for future changes in community structure. Here we describe a natural analogue site in the Western Baltic Sea. Seawater pCO2 in Kiel Fjord is elevated for large parts of the year due to upwelling of CO2 rich waters. Peak pCO2 values of >230 Pa (>2300 μatm) and pHNBS values of 400 Pa (>4000 μatm). These changes will most likely affect calcification and recruitment, and increase external shell dissolution.
The role of total factor productivity in 'Phoenix Miracles': insights from an emerging market crisis

Key macroeconomic variables such as GDP and investment typically display a V-shaped pattern during major emerging market crises. A notable exception to that pattern is intermediated credit, which follows an L-shaped trajectory instead: it declines at first in lockstep with economic activity, but later on it fails to recover while output does. From the vantage point of ? credit crunch? theories of crises, it is as if output almost literally ? rises from its ashes,? prompting the metaphoric characterization of emerging markets post-collapse recoveries as Phoenix Miracles. ; This paper reorganizes the evidence for a particular emerging market crisis, the one that Argentina experienced in 2000-01, under the guide of the neoclassical growth model. Under that lens, there is nothing special about the V-shaped trajectory that GDP, investment, and labor input followed during the crisis and its aftermath. That is exactly the pattern, and in the same orders of magnitude, that a neoclassical growth model with TFP taken as exogenous would predict. Furthermore, from the vantage point of that model, there is no Phoenix Miracle: the post-collapse recovery of TFP and GDP was about as strong as the model would have predicted.
Generic Inference on Quantile and Quantile Effect Functions for Discrete Outcomes

Abstract Quantile and quantile effect (QE) functions are important tools for descriptive and causal analysis due to their natural and intuitive interpretation. Existing inference methods for these functions do not apply to discrete random variables. This article offers a simple, practical construction of simultaneous confidence bands for quantile and QE functions of possibly discrete random variables. It is based on a natural transformation of simultaneous confidence bands for distribution functions, which are readily available for many problems. The construction is generic and does not depend on the nature of the underlying problem. It works in conjunction with parametric, semiparametric, and nonparametric modeling methods for observed and counterfactual distributions, and does not depend on the sampling scheme. We apply our method to characterize the distributional impact of insurance coverage on health care utilization and obtain the distributional decomposition of the racial test score gap. We find that universal insurance coverage increases the number of doctor visits across the entire distribution, and that the racial test score gap is small at early ages but grows with age due to socio-economic factors especially at the top of the distribution. Supplementary materials (additional results, R package, replication files) for this article are available online.
Harmonic generation and energy transport in dielectric and semiconductors at visible and UV wavelengths: the case of GaP

We study the propagation and momentum transport of the inhomogeneous component of second and third harmonic pulses in dielectrics and semiconductors, at visible and UV wavelengths, focusing on materials like GaP. In these spectral regions GaP is characterized by large absorption, metallic behavior or a combination of both. We show that phase locking causes the generated inhomogeneous signals to propagate through a bulk metallic medium without being absorbed. This means that it occurs even in centrosymmetric materials thanks to the magnetic Lorentz force. We show that the transport of energy and momentum is quite peculiar and it can appear as anomalous, and that the direction of the Poynting vector of some of the harmonic pulses does not follow Snell’s law after crossing the interface. These results make it clear that there are new opportunities in ultrafast nonlinear optics and nanoplasmonics in new wavelength ranges.
A Near Optimal Approach in Choosing The Appropriate Physical Machines for Live Virtual Machines Migration in Cloud Computing

Migration of Virtual Machine (VM) is a critical challenge in cloud computing. The process to move VMs or applications from one Physical Machine (PM) to another is known as VM migration. In VM migration several issues should be considered. One of the major issues in VM migration problem is selecting an appropriate PM as a destination for a migrating VM. To face this issue, several approaches are proposed that focus on ranking potential destination PMs by addressing migration objectives. In this paper we propose a new hierarchal fuzzy logic system for ranking potential destination PMs for a migrating VM by considering following parameters: Performance efficiency, Communication cost between VMs, Power consumption, Workload, Temperature efficiency and Availability. Using hierarchal fuzzy logic systems which consider the mentioned six parameters which have great role in ranking of potential destination PMs for a migrating VM together, the accuracy of PMs ranking approach is increased, furthermore the number of fuzzy rules in the system are reduced, thereby reducing the computational time (which is critical in cloud environment). In our experiments, we compare our proposed approach that is named as (HFLSRPM: Hierarchal Fuzzy Logic Structure for Ranking potential destination PMs for a migrating VM) with AppAware algorithm in terms of communication cost and performance efficiency. The results demonstrate that by considering more effective parameters in the proposed PMs ranking approach, HFLSRPM outperforms AppAware algorithm.

Efficacy of vegetable oils against dry bean beetles Acanthoscelides obtectus.

Acanthoscelides obtectus (Say) is a major pest of stored dry beans ( Phaseolus vulgaris L.) and other legumes world wide. The objective of this study was to assess the efficacy of castor (Ricinus communis L.) and cottonseed ( Gossypium hirsutum ) oils against A. obtectus on stored dry beans under laboratory conditions. Castor and cottonseed oils at 0, 3, 4.5, 6, 7.5 and 9 ml kg -1 were tested against A. obtectus . All bioassays were conducted at 28 ± 1 °C and 65 ± 5% relative humidity, and mortality recorded after 24, 48, 72, 96 and 120 hr of exposure. After the 120 hr mortality count, all the adults were removed and the vials were maintained at the same conditions for 35 days to assess progeny production. Mortality of A. obtectus significantly (P<0.05) increased with increase in dose of oil treatments and exposure interval. After 120 hr of exposure, mortalities were 99.1 and 74.1% at the highest dose (9 ml kg -1 ) with castor oil and cottonseed oil, respectively. The lowest LC 50 value of 2.95 ml kg -1 and complete suppression in progeny production were achieved on beans treated with castor oil at 9 ml kg -1 . However, in all treatments, the percentage of progeny reduction was more than 80%. In conclusion, results indicate that vegetable oils have great potential for A. obtectu s control. Key Words : Cameroon, castor, cotton, Phaseolus vulgari s, progeny reduction
Monoidal categorifications of cluster algebras of type A and D

In this note, we introduce monoidal subcategories of the tensor category of finite-dimensional representations of a simply-laced quantum affine algebra, parametrized by arbitrary Dynkin quivers. For linearly oriented quivers of types A and D, we show that these categories provide monoidal categorifications of cluster algebras of the same type. The proof is purely representation-theoretical, in the spirit of [HL1].
