Comparing Linear Discriminant Function with Logistic Regression for the Two-Group Classification Problem.

Abstract The performances of predictive discriminant analysis (PDA) and logistic regression (LR) for the 2-group classification problem were compared. The authors used a fully crossed 3-factor experimental design (sample size, group proportions, and equal or unequal covariance matrices) and 2 data patterns. When the 2 groups had equal covariance matrices, PDA and LR performed comparably for the conditions of both equal and unequal group proportions. When the 2 groups had unequal covariance matrices (4:1, as implemented in this study) and very different group proportions, PDA and LR differed somewhat with regard to the classification error rates of the 2 groups, but the classification error rates of the 2 methods for the total sample remained comparable. Sample size played a relatively minor role in the classification accuracy of the 2 methods, except when LR was used under relatively small sample-size conditions.
Nanoporous Silica-Based Materials for Sorption of Pharmaceuticals and Biomolecules

Abstract Our concern in this paper is to review four kinds of mesoporous silica materials which can be used as potential sorbents for pharmaceuticals. It is known that a continuous development of science, medicine and food industry has an effect on contamination of the natural environment. Moreover, many impurities, such as drugs, vitamins or proteins etc., which get into environment from urban and hospital wastes, can also influence on human organisms. Thus, there is a need to control an amount of those compounds, especially in the natural waters and wastewaters [1-4]. In this work, we present four types of silica materials which can be helpful in water purification by using adsorption process.
Managing the gap between policy and practice through Intermediaries for Quality Improvement

A gap exists between policymaking for quality improvement and the realization of these policies in practice. Using previous research on intermediaries, a conceptual model of an Intermediary for Quality Improvement (IQI) is developed. The model highlights the characteristics of structural positions, mediating approaches, and duration as a way to describe an IQI. The conceptual model is used to examine two cases in which Famna, the Swedish Association for Non-profit Health and Social Service Providers, has supported both policymaking and the implementation of policies at a provider level. The cases are the national strategy for quality improvement by open comparisons in health care and social services and a new regulation on quality management systems in health care and social services. Using the concept of an IQI deepens the understanding of how top-down and bottom-up perspectives may be managed to realize good quality of services.
Image Matching Algorithm for Remote Sensing based on FAST-9 and SURF

A novel remote sensing image matching algorithm based on FAST-9 and SURF is proposed. Firstly, the FAST-9 is employed to detect feature points for remote sensing images, and the ID3 algorithm and non maximum method are used to determine the correct corners. And then, main orientation is assigned by the circular region around the interest point. The SURF descriptor is constructed by the square region aligned to the selected orientation. Finally, the matching pairs are calculated by the nearest neighbor distance matching method. Experimental results show that the proposed matching algorithm is effective for remote sensing images, which has excellent invariance.
A Selective Under-Sampling based Bagging SVM for Imbalanced Data Learning in Biomedical Event Trigger Recognition

Because of the importance of the biomedical events in understanding the biomedical processes and functions, extraction of events from biomedical literature automatically becomes the recent research focus, which can update the existing biomedical knowledge faster. Recognition of trigger words is a very important first step for event extraction, since the following extraction steps depends on the outputting trigger words. The application of event trigger recognition aims to classify different kinds of trigger words from very large biomedical literature data sets with significant imbalance between classes. However, many existing classification methods show great limitations and performance decline on imbalanced and large data sets. In this paper, a selective under-sampling based bagging Support Vector Machine, SUS Bagging-SVM, approach has been proposed to address the issues together in an ensemble learning framework. Through making use of boundary information, a novel selective under-sampling method was designed to prune unimportant instances from the majority class to reduce imbalance in large data sets effectively. SUS Bagging-SVM was tested on the corpus of BioNLP'09 shared task. It achieved a total F1-measure of 66.1, which is competitive in comparison with other state-of-art trigger recognition systems, and a higher recall value. In conclusion, SUS Bagging-SVM is a valuable method for alleviating the problem of classification on imbalanced and large data.
COORDINATION CONTROL OF MICROGRID

It is necessary to electrify remote locations with a micro-grid by means of existing renewable energy sources available locally. The microgrid configuration represents the energy distribution architecture from the generating sites to the consumers and finally the interconnection between these sites and consumers. The hybrid grid consists of both ac and dc networks connected together by bidirectional converters . The hybrid ac/dc micro grid is used to reduce the processes of dc–ac–dc or ac–dc–ac conversions in an individual ac or dc grid.AC sources and loads are connected to the ac network whereas dc sources and loads are tied to the dc network. Energy storage systems can be connected to dc or ac links. The coordination control techniques are proposed for smooth power transfer between ac and dc links and for stable system operation under various generation and load conditions. The proposed hybrid grid can operate in a grid-tied or autonomous mode. Here photovoltaic system, wind turbine generator and battery are used for the development of Hybrid Microgrid. Also control mechanisms are implemented for the converters to properly coordinate between the AC sub-grid and DC sub-grid. The system is simulated in the MATLAB/ SIMULINK environment.
Micro- and macroscopic simulation of periodic metamaterials

Abstract. In order to characterize three-dimensional, left-handed metamaterials (LHM) we use electromagnetic field simulations of unit cells. For waves traveling in one of the main directions of the periodic LHM-arrays, the analysis is concentrated on the calculation of global quantities of the unit cells, such as scattering parameters or dispersion diagrams, and a careful interpretation of the results. We show that the concept of equivalent material values – which may be negative in a narrow frequency range – can be validated by large "global" simulations of a wedge structure. We also discuss the limitations of this concept, since in some cases the macroscopic behavior of an LHM cannot be accurately described by equivalent material values.
Hidden Optimal Principle in Quantum Mechanics and Quantum Chemistry

Quantum Mechanic axio ms are the result of the microscopic cooperative equilibriu m among sym metric p layers (quantum object and human subject). On the other hand, we introduce Nash's equilibriu m in Hilbert space, which has two characteristics: it is a fixed point and it maximizes a utility function. Moreover, evolution and selfadjoint operators have interesting properties which allow us to study steady state in Evolutionary Game Theory. Also, we present cooperative games in co mplex systems language.The concept of cooperation is important in game theory but is somewhat subtle. The term cooperate means "to act together, with a common purpose". Incentive compatibility is equivalent to synergy principle, which appears naturally (to add or to multiply utilit ies, ec(34)). Finally, wein the relevant results not only proved the main theorems of Quantum Mechanics, Quantum Chemistry and its applications to salt-water but also we resolved some main questions such us: Do hydrogen-bonded networks, in which tunneling plays an important role, exist? , Ho w cooperation and entropy affect water cluster equilibria? Can salt (ClNa) p lay an Nobel role in photo-catalysis? The answers are: tunnel effect it is possible in salt water but not in water, because ClNa, visib le light or electricity incentive to produce catalysis or photo-catalysis. Also, If hydrogen-bonded networks and water cluster size increases complexity of an global equilibriu m, then tunnel effect appears as an local equilibriu m.
Amelioration of Soybean Plant from Saline-Induced Condition by Exopolysaccharide Producing Pseudomonas -Mediated Expression of High Affinity K + -transporter (HKT1) Gene

There is a consensus that soil salinization causes decreased agricultural production. Several plants may adapt to survive under high salt stress wherein glycophytes fail to grow. Among transporters in plants, the sodium transporter, also known as high-affinity K + -transporter ( HKT1 ) that comes under the HKT gene family, is involved in uptake of sodium through the roots and its recirculation from shoot to root. In the present study, we have examined the role of transporter HKT1 in soybean plants upon addition of 200 mM NaCl and treatment with Pseudomonas sp. strain AK-1. It is reported that HKT1 is permeable to K + /Na + and systemically alleviates salinity stress through upregulation of gene expression in shoots and down-regulation in roots. Higher transcription levels in shoot recirculate Na + from shoot xylem to root phloem whereas lower transcription levels in root do not allow sodium to enter the plants through root cells. We have also examined role of exopolysaccharide (EPS) produced by strain AK-1 which helps in the binding of free Na + from soil and thus makes Na + unavailable to the soybean plants. Strain with EPS showed decrease in electrical conductivity of soil from 1.1 to 0.9 dS/m in the presence of 200 mM NaCl. In conclusion, treatment with Pseudomonas sp. strain AK-1 exhibits significant rise in shoot/root length, number of lateral roots, shoot/root fresh weight and decreased Na + /K + ratio under salinity stress.
FIELD MEASUREMENT OF SHRINKAGE CRACK DEPTH IN EXPANSIVE SOILS

The depths of surface cracks in expansive clay deposits control the depths of the active zone in many cases. Rainfall and surface runoff can fill these cracks, and the water in the cracks can travel, impelled only by gravity, wherever the crack goes. If the water travels beneath a pavement, it will remain there, soaking into the soil on each side of the crack, and cause swelling. Thus, the depth of the surface cracks determines the depth to which a vertical moisture barrier should be placed in order to control moisture beneath a pavement, and a means of determining this depth is needed. This paper describes such a method using wave propagation. A summary review of wave types is included--their generation, propagation, and alteration at a crack, and the feasibility of their detection and positive identification. This is complemented by the selection of several trial procedures for detecting surface cracks and estimating their depth. The results of field tests using several trenches excavated to different depths and at naturally occurring shrinkage cracks are presented. The testing setups are illustrated and the analysis performed with the field data is described. The best approach to determine the depth of the crack is from the increase in travel time of the surface wave caused by the crack.
Corporate Governance, Corporate Size, Corporate Industry, Corporate Social Responsibility Disclosure Size and Stock Price

The objective of this research is to test whether there are relationships between corporate governance, corporate size and industry category with corporate social responsibility (CSR) disclosure size, and also the implication of CSR disclosure size to corporate performance (stock price). The research model has the combined research model from the two models. The first model is to describe the relationship between corporate size, industry category, and corporate governance with CSR disclosure size, and the second model is to find that between CSR disclosure size with corporate performance (stock price). The research result from the first model shows that industry type and corporate governance index have a significant relationship with corporate social responsibility disclosure size. The second model shows that CSR disclosure size has a significant relationship with corporate stock price.

Dynamical Asteroseismology: towards improving the theories of stellar structure and (tidal) evolution

The potential of the dynamical asteroseismology, the research area that builds upon the synergies between the asteroseismology and binary stars research fields, is discussed in this manuscript. We touch upon the following topics: i) the mass discrepancy observed in intermediate-to high-mass main-sequence and evolved binaries as well as in the low mass systems that are still in the pre-main sequence phase of their evolution; ii) the rotationally induced mixing in high-mass stars, in particular how the most recent theoretical predictions and spectroscopic findings compare to the results of asteroseismic investigations; iii) internal gravity waves and their potential role in the evolution of binary star systems and surface nitrogen enrichment in high-mass stars; iv) the tidal evolution theory, in particular how its predictions of spin-orbit synchronisation and orbital circularisation compare to the present-day high-quality observations; v) the tidally-induced pulsations and their role in the angular momentum transport within binary star systems; vi) the scaling relations between fundamental and seismic properties of stars across the entire HR-diagram.
Study on the influence benzyladenine (BA), added in various concentrations to the culture medium, of regeneration explain Aylostera (Speg.) heliosa.

Aylostera heliosa is a cactus with a great decorative potential, both the flowers and the harbor, but difficult multiplied by grafting, for which it seeks a way of spreading fast and secure and virus free seedlings. Future inoculated Aylostera heliosa were harvested under sterile conditions from young stems cut into slices about 1 cm length spherical, 0,5 cm thick and a diameter of 0,5-1,5 cm, depending on the area that were take, and at least 2-3 areolae. The explants were inoculated in a mineral medium - macro Murashige-Skoog (1962) with the addition of growth regulators, micronutrients Heller (1953), supplemented with benzyladenine BA or 6-benzylaminopurine - BAP at different concentrations. Evolution explants was monitored for 90 days. Their response was different depending on the concentration of BA present in the culture medium. Finally, it was shown that Aylostera heliosa explants grown in culture medium supplemented with 2 mg /l BA (V3) had the most and largest strain newly formed. Procrsul of callus was manifested only explants grown in culture medium devoid of growth regulators (V0 - control), whereas no rooting was observed in any of varinatele experienced.
Inflation Targeting in Presence of Balassa-Samuelson-Type Productivity Shocks

This paper develops a two-sector small open-economy dynamic stochastic model with permanent technology shocks and price rigidities that allows for simulation of the differential productivity growth (Balassa-Samuleson-type productivity improvement). In addition, the model incorporates quality improvement to replicate typical terms of trade dynamics in new EU members. The model is calibrated for a typical new EU member country to asses whether the Balassa-Samuelson effect poses a threat to fullfiling the inflation Maastricht criterion. In addition, optimal policy is derived for a benchmark parameterization of the model. The results show that productivity growth differential need not generate the inflationary effects that represent significant risks to fullfilling Maastricht criteria in the ERM II.
ENTREPRENEURIAL POTENTIAL PROFILE MEASUREMENT AND IT’S IMPACT ON SMALL BUSINESS PERFORMANCE

The entrepreneurship issue has been widely broadcasted among both academic and business environment by means of publications, practical cases and examples from entrepreneurs who are well succeeded in their business career. Small companies are considered to be one of the main agents of development and economic growth of a country. Considering this scenario, the present research aims to build an instrument to identify which are the main factors that form the entrepreneur’s profile. In order to achieve that objective, 965 questionnaires were collected. According to the research’s results, the EPPEntrepreneur Potential Profile is composed by eight factors: strategic competence, risk, innovation, formal planning, relationship, analytical thinking, dedication and challenge. Through Structural Equation Modeling, it was verified that the EPP (Entrepreneur Potential Profile) could explain for 25% of the performance in a small business.
Pedestrian Guiding Signs Optimization for Airport Terminal

The pedestrian guiding sign (PGS) is used to lead people within the transportation terminal to their directions efficiently and without boundaries. In this paper, we aim to optimize the guiding signs for people in the comprehensive transportation terminal with a mathematical model, which describes the pedestrian's reaction, judgment, and perception of the outline about the guiding signs, as well as pedestrian's moving status through self-organized characteristic behavior. Furthermore, the model also reflects the information intensity of the guiding signs within the pedestrian's visual field which is taken as the influence level score of PGS. In order to solve the model, cellular automation (CA) is employed to simulate the characteristics of the pedestrians such as crowd moving and sign selection.

Preparation of 11-Hydroxylated 11,13-Dihydrosesquiterpene Lactones

Se llevaron a cabo hidroxilaciones de las posiciones α- del grupo carbonilo lactonico en cuatro esqueletos diferentes de 11,13-dihidro- derivados de lactonas sesquiterpenicas (germacranolidas, eudesmanolidas, guayanolidas y elemanolidas), mediante la generacion del enolato con LDA y su atrapamiento con oxigeno gaseoso o con un agente oxidante quiral, (canforilsulfonil)aziridina. Las oxidaciones con oxigeno no fueron estereo-especificas y generaron las hidroxilactonas 11α- y 11β- en rendimientos combinados que fluctuan entre 13 al 47 %, junto con cetonas norsesquiterpenicas, que se forman probablemente por la descomposicion de los aniones hidroperoxidos intermediarios. La hidroxilacion de la germacranolida 11,13-dihidropartenolida, con (+)- o (−)- (canforilsulfonil)-aziridina produjo la 11β-hidroxilactona exclusivamente (66-72 %), sin detectarse la cetona norsesquiterpenica
Causes of delays in construction works resulting from the provisions of the contract in Poland and Slovakia

Exceeding the time limit of works implementation specifi ed in the contract is a common problem in the construction industry and is signifi cant for both the investor and the contractor. As shown by studies conducted in developed and developing countries, delays in construction works are a common and frequently recurring problem in the implementation of construction projects (Toor & Ogunlana, 2008). For the investor, a delay may mean the inability to obtain benefi ts of the investments at the scheduled time, and in special situations, it may turn a profi table venture into an unviable project. For the contractor, this may mean higher than planned costs of works. In extreme cases this can lead to a situation in which, instead of planned profi t, the contractor incurs losses. The provisions of the agreement between the investor and the contractor decide which party is going to be responsible for delays. On these grounds, the way the risks related to the implementation of construction works are distributed between the parties is established. Early identifi cation and the subsequent limitation or even elimination or the potential reasons for such delays may contribute to the effi cient and punctual project completion. The paper presents the results of research dealing with building contractors in Poland and Slovakia. The aim of the research was the identifi cation and rating the signifi cance of factors that may generate delays in construction works in both countries.

Prediction of Social Comparison Based on Perfectionism, Self-Concept Clarity, and Self-Esteem

Background: Eating and body image disorders are 2 of the most debilitating clinical problems among female adolescents and young females. One of the strongest factors contributing to body dissatisfaction and eating pathology is social comparison. Objectives: The current study aimed at determining the relationship between perfectionism, self-concept clarity, and self-esteem and the share of prediction of each in social comparison. Methods: The current cross sectional study included all female high school students in Tehran in the 2014 - 2015 academic year. Of these, 477 females were selected by multistage cluster sampling. Results: The results of the correlation matrix was indicative of a significant negative relationship between self-esteem and self-concept clarity with social comparison (P < 0.000). There was a significant positive relationship between perfectionism and social comparison (P < 0.000). The results of stepwise regression revealed that self-concept clarity predicted 17% of social comparison variance. By including the variables of perfectionism and self-esteem, the coefficients of determination increased significantly up to 24% and 26%, respectively. Self-esteem and self-concept clarity were significant negative predictors (P < 0.000), while perfectionism was a significant positive predictor (P < 0.000) of social comparison. Beta coefficients indicated that among the predictive variables, self-concept clarity, and self-esteem were able to predict social comparison more than perfectionism (β = -0.28, β = 0.27, and β = -0.18, respectively). Conclusions: Targeting individual differences that make people vulnerable to social comparison not only contributes to understanding the development of eating problems and body image, but also has implications for prevention and treatment.
