Graph Hybrid Summarization

One solution to process and analysis of massive graphs is summarization. Generating a high quality summary is the main challenge of graph summarization. In the aims of generating a summary with a better quality for a given attributed graph, both structural and attribute similarities must be considered. There are two measures named density and entropy to evaluate the quality of structural and attribute-based summaries respectively. For an attributed graph, a high quality summary is one that covers both graph structure and its attributes with the user-specified degrees of importance. Recently two methods has been proposed for summarizing a graph based on both graph structure and attribute similarities. In this paper, a new method for hybrid summarization of a given attributed graph has proposed and the quality of the summary generated by this method has compared with the recently proposed method for this purpose. Experimental results showed that our proposed method generates a summary with a better quality.
Structural, Electronic and Magnetic Properties of Geometrically Frustrated Spinel CdCr2O4 from First-principles Based on Density Functional Theory

First-principles calculations are used to investigate the structural, electronic, and magnetic properties of CdCr2O4 with magnetic Cr cations, focusing on the changes through the magnetic phase transitions which shows relief of the geometric frustration of the ferromagnetic and antiferromagnetic orderings on the pyrochlore lattice. We computed the structural and electronic properties for the paramagnetic, ferromagnetic and antiferromagnetic orderings in cubic ( F 3 dm) and tetragonal (I41 ⁄amd) structures of CdCr2O4. We optimized the crystal structures with the PM, FM and AFM orderings using a pseudopotential plane wave (PP-PW) method within the generalized gradient approximation (GGA), and computed the electronic properties to investigate the magnetic properties in the geometrically frustrated ferromagnetic and antiferromagnetic spinel CdCr2O4 based on density functional theory and understanding of the principles of Quantum ESPRESSO in magnetic materials. On the other hand, the effect of magnetism were obtained and analyzed on the basis of density of states (DOS), projected density of states (PDOS), and charge density distribution.
Influences of Different Milk Yields of Holstein Cows on Milk Quality Indicators in the Czech Republic

Janů L. , O. Hanus, J. Frelich, a. Macek, I. Zajickova, V. Gencurova, R. Jedelska: Influences of Different Milk Yields of Holstein Cows on Milk Quality Indicators in the Czech Republic. acta Vet. Brno 2007, 76: 553-561. The milk yield (MY) is an important economic and health factor closely connected with the health status of dairy cows, their reproduction performance, longevity and milk composition and properties (MIs). The differences within MIs between high yielding herd (Group 1; 10 282 kg per lactation) and three herds with average MY (Group 2; 7 926 kg) were tested. The files with 96 and 290 milk samples were collected in summer and winter feeding seasons and well balanced in lactation factors. Group 1 had higher genetical value, better nutrition and was milked three times per day and its MY was higher by 30% ( P 0.05). The U was probably higher due to higher loading of the nitrogen nutrition (4.27 > 3.57 mmol·l -1 ) in MY 1. Surprisingly, SCC was higher (112 > 81 10 3 ·ml -1 ) and aC lower ((0.0374) 0.0250 0.05), despite the large difference between MY 1 and 2. URn was higher in MY 1 (46.5 > 39.1%) due to more efficient nutrition, like in U. The high MY had no negative impacts on MIs with well balanced nutrition of Holstein cattle.

Internal Models Validation in Brazil: Analysis of VaR Backtesting Methodologies

The purpose of this paper is to analyze backtesting methodologies of VaR, focusing on aspects as suitability to volatile markets and to limited data set. We verify, from regulatory standpoint, tests to complement the Basel trafﬁc light results, using simulated and real data. The results indicate that tests based on failures proportion are not adequate for small samples even for 1,000 observations. The Basel criterion is conservative and has low power, which does not invalidate its application, as the criterion is only one of the procedures adopted in internal models validation process. Thus, it is suggested using tests that capture the shape of returns distribution, as the Kuiper test, in addition to the Basel criterion.
Evaluation of Nutritional and Physical Properties of Watermelon Juice during the Thermal Processing by Using Alumina Nano-fluid in a Shell and Tube Heat Exchanger

Background and Objectives: Thermal processing is an effective method in preventing microbial spoilage but high heat transfer in a long time process that leads to quality loss and increased energy consumption. Also it is important to consider sensitive nature of food products during the thermal processing. Due to the nano-fluids' unique thermo–physical properties compared with the conventional fluids (steam and hot water), their use in various industries to enhance the efficiency of equipment and energy optimization has increased. Materials and Methods: The effects of alumina–water nano-fluids (0, 2, and 4% concentrations) on some nutritional properties (lycopene and vitamin C content), and some physical properties (color, pH and TSS) of watermelon juice treated by high temperature–short time (75, 80, and 85°C for 15, 30, and 45 seconds) in a shell and tube heat exchanger were evaluated. Results: In compared with water, process time reduced by 24.88% and 51.63% for 2% and 4% nano-fluids, respectively. It had a significant effect on improving the properties of watermelon juice (P<0.05). Under the treatment conditions (75°C and 15s), with 0, 2, and 4% nano-fluids, 81.15, 84.81, and 91.28% of lycopene and 61.11, 63.70 and 67.04% of vitamin C were maintained, respectively. ΔE* values for the fruit juices processed with 0, 2 and 4% nano-fluids were 3.26, 2.21 and 1.14, respectively. Also pH and TSS changed in the range of 5.58–5.82 and 9.00–9.40%, respectively. Conclusions: The results showed that qualitative and nutritional properties of watermelon juices processed with nano-fluids in terms of lycopene and vitamin C retention, and color were, respectively, 9.89, 6.18 and 50.38% better than the samples processed with water.
Who's in the joined-up government? Australian elected representatives adaptive responses to network technology

While the advent of Internet-based communications have had radical impacts on the way work processes are undertaken globally, the implementation of computer-mediated-communications within government has been the source of criticism from proponents of “electronic democracy”. Based on a new typology of electronic democracy initiatives and feasibility, this paper explores the adaptive responses of Australia’s Elected Representatives to the possibilities of democratic communication and consultation through online media. From a survey of over twelve hundred elected office holders, the paper examines uptake and interest in online communication and points towards adaptive trends for future electronic democracy initiatives from within Australian Parliaments and Councils.
Investigation uma spatial ecology in open habitats with aggregate prey

Solitary felids are commonly associated with structurally complex habitats, where their foraging success is attributed to stealth and remaining undetected by competitive scavengers. Research in North America suggests that pumas (Puma concolor), a wide-ranging species found throughout the Americas, conform to the general characteristics of solitary felids and avoid open grasslands with aggregating prey. Researchers hypothesize that pumas are limited to structurally complex habitats in North America because of pressures from other large, terrestrial competitors. We explored the spatial ecology of pumas in open habitat with aggregating prey in Chilean Patagonia, where pumas lack large, terrestrial competitors. We tracked 11 pumas over 30 months (intensive location data for 9 pumas with GPS collars for 9.33 ± 5.66 months each) in an area where mixed steppe grasslands composed 53% of the study area and carried 98% of available prey biomass, to track resource use relative to availability, assess daily movements, quantify home ranges and calculate their density. As determined by location data and kill sites, Patagonia pumas were primarily associated with open habitats with high prey biomass, but at finer scales, preferentially selected for habitat with complex structure. On average, pumas traveled 13.42 ± 2.50 km per day. Estimated 95% fixed kernel home ranges averaged 98 ± 31.8 km2 for females and 211 ± 138.8 km2 for males, with high spatial overlap within and between the sexes. In a multivariate analysis, available prey biomass was the strongest predictor of variation in the size of an individual puma’s home range. Finally, we determined a total puma density of 3.44 pumas/100 km2, a significantly smaller estimate than previously reported for densi sellsc Patagonia, but similar to
Occurrence of five nematode species from some Red Sea fishes, Yemen.

Between September 2010 and May 2011, a total of 228 specimens belonging to 11 different species of marine fishes were collected from Al-Mehwat fish market at Hodeidah city, Yemen, to be investigated for nematode infections. Five species of nematodes, belonging to three families, were detected. These were the adult form of Cucullanus bourdini Petter and Le Bel, 1992 and the third larval stages of Anisakis simplex (Rudolphi, 1809), Terranova sp. , Hysterothylacium sp. and Echinocephalus overstreeti Deardorff & Ko, 1983. C. bourdini was recorded from three fish species, A. simplex from all the eleven examined fish species, Hysterothylacium sp. from eight fish species, while both Terranova sp. and E. overstreeti were recorded from one fish species only. Adult nematodes were detected from fish intestine, while the larval parasites were detected from fish body cavity, mesenteries, stomach, intestine, liver, spleen, gonads and kidneys. For each parasite species, the prevalence, mean intensity and abundance were calculated for each infected host species. C. bourdini, Terranova sp. and Hysterothylacium sp. are recorded here for the first time from the Red Sea fishes of Yemen, while A. simplex and E. overstreeti were previously reported from some Red Sea fishes of Yemen. Among these five parasites, both A. simplex and Hysterothylacium sp. are known to have zoonotic importance.
Biosynthesis of silver nanoparticles using brown marine seaweed Padina boeregeseni and evaluation of physico-chemical factors

Present investigation consists the green nanoparticles prepared by using both fresh and dry marine macroalga of Padina boeregeseni was reported and the physical and chemical factors such as time duration, pH, various mixing ratios of aqueous extract to AgNO 3 solution and temperature that play vital role in the nanoparticles synthesis were assess. Maximum synthesis of silver nanoparticles was attained within 30 min at pH 8.5, 70°C and 1mM AgNO 3 . Characterization of silver nanoparticles was carried out based on UV-Vis spectrophotometry (418 nm). The size of nanoparticles synthesis with average of 43.3 nm was confirmed by scanning electron microscopy (SEM). X-ray diffraction (XRD) crystallography illustrated the silver nanoparticles crystalline nature. Fourier transform infrared spectroscopy (FTIR) shows that the function groups are hydroxyl, carbonyl, amine and phenol compounds of extract P.boeregeseni are involved in the reduction of aqueous AgNO 3 . This method of Ag-NPs synthesis does not use any toxic reagents and thus has potential for use in biomedical and agricultural application .
Can ?Keff be assumed as the driving force for fatigue crack growth?

This work raises some new questions about the validity of blindly assuming that Elber’s effective stress intensity factor is the actual fatigue crack driving force, and that as so it can be used to explain all load sequence effects on fatigue crack growth (FCG). Although plasticity-induced crack closure can be a quite reasonable heuristic explanation for many non-elementary FCG behaviors, it has some limitations that cannot be ignored. In fact, this never settled discussion is particularly important for the simulation of FCG lives under real service loads, a most important practical issue. After arguing that ? Keff can spoil the use of the most important similitude principle in FCG problems, simple but convincing experimental data that cannot be explained by this classical idea is presented here. This data involves the shape of fatigue crack fronts and the FCG behavior under nominally plane stress and plane strain conditions.
Finite-Temperature Spectral Functions from the Functional Renormalization Group

We present a method to obtain spectral functions at finite temperature from the Functional Renormalization Group. Our method is based on a thermodynamically consistent truncation of the flow equations for 2-point functions with analytically continued frequency components in the originally Euclidean external momenta. For the uniqueness of this continuation at finite temperature we furthermore implement the physical Baym-Mermin boundary conditions. Results are presented for mesonic spectral functions obtained from a two-flavor quark-meson model.

Construction of a Niche-Fitness Model
for Well-Facilitated Capital Farmland
and its Application

Today, constructing well-facilitated capital farmland on a large scale is one of the key strategic initiatives for enhancing the national capacity for food security. In order to strengthen the scientific and rational distribution of well-facilitated capital farmland, this article, starting with the discussion of ecosystem integrity of regional well-facilitated capital farmland on the basis of ecological niche theory, proposes the concept of ecological niche for well-facilitated capital farmland, and constructs “ecostate” and “ecorole” evaluation models (Ni model) of ecological niche for well-facilitated capital farmland. This is verified by studying the case of the city of Xinzheng, Henan Province, China. As the research result shows, first the condition of farmland in Xinzheng is generally good, and the farmland in the whole city is suitable for the construction of well-facilitated capital farmland covering 34,224.48 hm2, 63.18% of the total area, which is mainly distributed in the southern and northwestern parts of the city. Second, the evaluation results are generally in consistency with the actual situation, which indicates that the Ni model is scientific and realistic in the evaluation of suitability for constructing well-facilitated capital farmland. Meanwhile, the Ni values are helpful for indicating the suitability for regional well-facilitated capital farmland. Third, using the most suitable ecological niche to explain standards of construction for well-facilitated capital farmland, and matching n dimension resources ecological niche along with most suitable ecological niche to evaluate well-facilitated capital farmland will convey clear ecological significance and be quite helpful to develop plans and measures for constructing well-facilitated capital farmland based on the size and changes of niche-fitness values.
Analysis of Liquidity-Study on Indian Mid-Cap Stocks

Liquidity is the pre-condition for a well-functioning and efficient market. Liquidity can be perceived, but difficult to measure due to its multi-dimensional characteristics. Studies have discussed various characteristics of liquidity and its influencing power on return and asset pricing. The article has considered Indian MidCap stocks and measured its liquidity using Amihud and trading volume as proxies. It has found Indian MidCap stocks have varying degree of liquidity. During the intraday, MidCap stocks have L-shaped liquidity pattern. The article observed that P-E ratio, P-B ratio, Dividend Yield and Index of Industrial Production are the significant determinants of liquidity. The article has estimated liquidity betas and carried out Granger non-causality test to articulate its relation with CAPM beta. The article has also found stability of liquidity beta across MidCap stocks. The liquidity betas of MidCap stocks have time-varying volatility. Relative Strength Index (RSI) and Change in Trading Volume are exogenous variables in explaining the time-varying volatility of beta. The study observed that MidCap stocks are claiming liquidity premium and liquidity premium is influencing the asset pricing along with WML, HML and EMR factors.
The Economic Pay-Offs to Informal Training: Evidence from Routine Service Work

This study examines the relationship between informal training and job performance among 2,803 telephone operators in a large unionized U.S. telecommunications company. The authors analyze individual-level data on monthly training hours and job performance over a five-month period in 2001 as provided by the company's electronic monitoring system. The results indicate that the receipt of informal training was associated with higher productivity over time, when unobserved individual heterogeneity is taken into account. Workers with lower pre-training proficiency showed greater improvements over time than did those with higher pre-training proficiency. Finally, whether the trainer was a supervisor or a peer also mattered: workers with below-average pre-training proficiency achieved greater productivity gains through supervisor training, while workers with average pre-training proficiency achieved greater productivity gains through peer training.
A tentative comparison of the performance of Strategic Alliance and Design/Bid/Build project delivery methods

Project delivery methods that are based on the concept of supply chain integration are believed by many to lead towards a more effective and more efficient way of working than other, more traditional ways of project delivery like the design-bid-build (DBB) method. This tentative study compares the cost performance of strategic alliance (SA) with that of a DBB. based on cost estimates at the Pre-construction stage. The cost estimates of three SA’s have been compared to three DBB cost estimates, which have been made by three external cost consultants, to see if there are indication of one project delivery method is superior. Three large scale housing renovation projects which are delivered by a similar form of SA have been selected for this study. The three alliances exist of different clients, contractors and subcontractors which are working in different regions. The target cost estimates made by the SA’s for the three projects have been compared with external cost estimates. These external cost estimates have been made by three different external cost consultants. The external cost estimates were made based on the assumption that the project would be delivered based on a traditional DBB method. The external cost consultants weren’t informed about the SA that was set up to deliver the project. Project costs per element were compared. Upon completion of the analysis, the hypothesis that SA projects are superior to DBB projects in regards to costs was researched.
Comparing the democratic value of facebook discussions across the profiles of Spanish political candidates during the 2011 general election

espanolEl articulo examina el valor democratico de los comentarios ciudadanos en los perfiles de Facebook de tres candidatos politicos espanoles durante la campana de las Elecciones Generales 2011 a traves de una operacionalizacion de la democracia deliberativa. Los resultados reflejan que las conversaciones no cumplen los criterios deliberativos, pero que aun asi revisten beneficios democraticos, como la autoexpresion ciudadana, la socializacion democratica y el refuerzo de la cohesion social entre activistas y simpatizantes. Ademas, reflejan que el valor democratico varia ligeramente en funcion del tamano del partido donde se produce. La conversacion en los muros de candidatos que pertenecen a partidos mayoritarios esta orientada hacia la autoexpresion, pero tambien confronta a los hablantes esporadicamente con la diversidad. Por su parte, la discusion en el muro de la candidata de un partido minoritario es ideologicamente homogenea, pero incluye mas interaccion discursiva, permitiendo desarrollar argumentario y cultivar la cohesion social en condiciones discursivas favorables. EnglishThis article examines the democratic value of user-generated comments on the Facebook profiles of three Spanish candidates during the Spanish General Election campaign of 2011 through a content analysis that operationalizes deliberative democracy. The findings show that these online spaces do not meet deliberative standards, but that they still serve democratic functions, such as citizen self-expression, democratic socialization and reinforcement of social cohesion among party activists and sympathizers. Moreover, results indicate that democratic value might vary depending on the size of the party where talk takes place. Political conversation on the walls of hegemonic candidates who belong to big consolidated political parties is mostly oriented towards self-expression and features some ideological diversity, so that individuals are sporadically confronted with diversity. For its part, talk on the Facebook profile of the minor candidate lacks fundamental disagreement but includes more in-group interaction, allowing minority ideological spheres for the cultivation of social cohesion and the construction of collective narratives in favorable discursive conditions.
Towards genetic engineering of maritime pine (Pinus pinaster Ait.)

Using our improved protocols for somatic embryogenesis in Pinus pinaster, transgenic tissues and plantlets were recovered after mi- croprojectile bombardment (biolistic) or cocultivation of embryonal-suspensor masses (ESM) with Agrobacterium tumefaciens. Transformation experiments were carried out with selectable hpt gene (hygromycin B resistance) and reporter gus gene (β-glucuronidase activity). With both methods, hygromycin was shown to be an effective selective agent of transformed cells within 4-19 weeks. The mean number of hygromy- cin-resistant lines expressing gus per gram ESM subjected to DNA transfer, ranged from 7.0 to 8.5 using biolistic and 0 to 67.3 during Agrobac- terium experiments. Mature somatic embryos obtained from some transformed lines were converted into plantlets and grown in the greenhouse. The whole process (from transformation to plant acclimatisation) could be completed within only 12 months. The transgenic state of ESM, so- matic embryos and plants was confirmed by histochemical GUS assays and molecular methods.
