Predicting Links and Their Building Time: A Path-Based Approach

Predicting links and their building time in a knowledge network has been extensively studied in recent years. Most structure-based predictive methods consider structures and the time information of edges separately, which fail to characterize the correlation between them. In this paper, we propose a structure called the Time-Difference-Labeled Path, and a link prediction method (TDLP). Experiments show that TDLP outperforms the state-of-the-art methods.
Morphological variability in populations of the fiddler crab Leptuca uruguayensis (Nobili, 1901) (Crustacea, Decapoda, Ocypodidae) from South America

Um estudo comparativo sobre o tamanho e a forma de Leptuca uruguayensis foi realizado entre as populacoes do Rio das Garcas, Brasil (BP) e do Rio Solis Grande, Uruguai (UP). O tamanho do inicio da maturidade sexual, tambem foi estimado para UP. Foi analisado um total de 36 individuos para BP e 387 para UP. Para a analise do crescimento relativo, a largura da carapaca (LC) para ambos os sexos, comprimento do maior quelipodo (CMQ) dos machos e a largura do abdome (LA) das femeas foram mensurados. O tamanho da carapaca e do quelipodo foi maior em UP. A forma tambem diferiu, sendo a carapaca de UP mais ampla do que BP; rostro projetado para a frente e margem posterior posicionada mais anteriormente; o quelipodo de UP tambem foi mais amplo do que BP. Em UP, a LC variou de 4,28-19,5 mm (machos) e 2,53-16,3 mm (femeas); o CMQ variou de 1,79-31,60 mm (machos) e a LA de 0,80-8,53 mm (femeas). O inicio da maturidade sexual para UP foi estimado em 12,20 mm LC (machos) e 7,81 mm (femeas). Essas diferencas podem indicar que variaveis abioticas estao atuando distintamente nas duas localidades.
Comparison of approximate inverse preconditioners for the fractional step Navier--Stokes equations

Sparse approximate inverses are applied as preconditioners for the fractional step solution of the Navier--Stokes equations. An advantage of this method is that its implementation requires only matrix-vector products and hence is relatively easy to parallelise. Since the coefficients for the pressure Poisson equation are constant, sparse approximate inverses need to be constructed only once, and are recalled in the subsequent iterations. Using the three dimensional turbulent channel flow as a test case, this study shows that the sparse approximate inverse preconditioners have comparable sequential performance to the Incomplete Lower-Upper preconditioner with same amount of fill to the original coefficient matrix.

Driving to a fast IMS feature vector computing

Increasing amount of image data transmitted via Internet has triggered the development of general purposes Image Mining Systems (IMS). An IMS performance relies on a good and fast feature vector specification that describes univocally an entire image. Vector size and the relationship between each evaluated feature and its computation time are critical, moreover when the image amount is big enough. Decreasing this IMS computational complexity by means of parallelism at the different involved tasks is one solution. Nowadays clusters of computers are already widely used as a low cost and high utility option to special-purpose machines, and suited to solve image processing problems with a high degree of data locality and parallelism. At this paper, we will focus on parallelism into the IMS processing stage trying to accelerate the feature vector calculus thru a cluster architecture attempting to give a better performance to the whole image mining system.
Exploring the Journals using Artificial Bee Colony algorithm

: The assessment of academic journals is a critical task to numerous scientific actions. These assessments may have an important influence on various issues reaching from publishing articles in academic journals to determining. The main aim is to develop the system that have the fair means of the selection of the best journal. Here we propose the system for ranking the journals in a huge data set which may include both similar and dissimilar distances of values from which the effective means of results being declared. A method for exploring the journals using, Artificial Bee Colony algorithm is presented to lessen the effort in working with the growth of data volumes. Artificial Bee Colony (ABC) is introduced for web mining for the both Journal Citation Reports and proposed data sets. This algorithm results us with relevant information for the questions posted by the clients when related to present Fuzzy c-means algorithm.
Potential of Natural Ventilation in Shopping Centres

SUMMARY The indoor environmental quality (IEQ) is a fundamental requirement for a well performing shopping centre. This paper contains a pilot study of the potential of using hybrid ventilation (a combination of automatically controlled natural and mechanical ventilation - respectively NV and MV) in shopping centres with focus on both the achieved IEQ and energy consumptions for air movement. By thermal building simulations it is found that there exists an interesting potential for hybrid ventilation of shopping centres, which can lead to great savings in the electrical energy consumptions for ventilation and cooling without compromising IEQ.
Positive Thoughts Coping Strategy as a Mediator Variable Between Perfectionism and Depression

This study explores the mediating role of positive thoughts and self-blame coping strategies between dimensions of perfectionism and anxiety. Three hundred and seventy-nine undergraduate students completed the FMPS (Frost Multidimensional Perfectionism Scale), CERQ (Cognitive Emotion Regulation Questionnaire), and DASS-42 (Depression Anxiety Stress Scales). The final path analysis fits the data well (CFI = 0.99, RMSEA = 0.068). Also sex and educational grade significantly predict anxiety. The relationships between dimensions of DA (doubts about action) and CM (concern over mistakes) perfectionism and anxiety are entirely mediated by the positive thoughts dimension. The results suggest that cognitive emotion strategies may be a valuable context of prevention and intervention.
Contrasting visions for aid and governance in the 21 st century : the White House Millennium Challenge Account and DFID s Drivers of Change GPRG-WPS-062

Governance is becoming increasingly important in development and poverty reduction policies. However, the forms and methods by which it is to be incorporated into donor programs are only emerging at present. In this paper, we contrast two very different approachesthe White House led Millennium Challenge Account (MCA) and DFIDs Drivers of Change (DOC) Approachto analysing governance, and compare their theoretical underpinnings. A key factor explaining why these different approaches have been adopted is that for the USA, global poverty reduction is a footnote to its foreign policy and national security agenda, whereas in the UK, global poverty reduction engages both the national political leadership and the civil society. In the conclusion, the paper suggests that enduring contradictions confronted by all donors complicate the treatment of governance in empirically nuanced terms (as DOC attempts to do) while privileging a more universalistic approach like the MCA.
Testing construct validity of verbal versus numerical measures of preference uncertainty in contingent valuation

The numerical certainty scale (NCS) and polychotomous choice (PC) methods are two widely used techniques for measuring preference uncertainty in contingent valuation (CV) studies. The NCS follows a numerical scale and the PC is based on a verbal scale. This report presents results of two experiments that use these preference uncertainty measurement techniques. The first experiment was designed to compare and contrast the uncertainty scores obtained from the NCS and the PC method. The second experiment was conducted to test a preference uncertainty measurement scale that combines verbal expressions with numerical and graphical interpretations: a composite certainty scale (CCS). The construct validity of the certainty scores obtained from these three techniques was tested by estimating three separate ordered probit regression models. The results of the study can be summarised in three key findings. First, the PC method generates a higher proportion of ‘yes’ responses than the conventional dichotomous choice elicitation format. Second, the CCS method generates a significantly higher proportion of certain responses than the NCS and the PC methods. Finally, the NCS method performs poorly in terms of construct validity. Overall, the verbal measures perform better than the numerical measure. The CCS is a promising method to measure preference uncertainty in CV studies. To better understand its strengths and weaknesses however, further empirical applications are needed.
Avian Pox in a Blue Rock Pigeon- A Case Report

Avipoxviruses (APVs), belonging to subfamily Chordopoxvirinae of the family Poxviridae, are the largest group of slowly spreading viruses affecting over 232 avian species including both domestic as well as free ranging birds viz., crow, sparrow, pigeons, partridges, mynahs, peafowls, eagle, hawk etc. (Joshi et al., 2012). The disease is transmitted mostly by mosquitoe bites and mites, and also through aerosol generated from infected birds, or by ingestion of contaminated feed or water. The disease occurs in two forms: cutaneous (dry form) and diphtheritic (moist form). The former develops as small papule, later progress to wart like scab on the unfeathered areas of skin while the latter develops a diphtheritic membrane in the upper respiratory and digestive tract (Mohan and Trevor, 2008). The most common method of transmission of dry form is through mosquito bites while that of wet form is through aerosol. Mortality and morbidity due to pox virus infection may be very high in pigeons (Tripathy, 1991). The diagnosis of a pox virus infection can be made based on the external clinical examination and gross lesions (Heuschele, 1986) but it is necessary to confirm the disease in the cutaneous form by the presence of characteristic Bollinger bodies in epithelial cells of epidermis by histopathologic analysis (Heuschele, 1986 and Randall and Reece, 1996).

A NOVEL APPROACH OF INDEXING AND RETRIEVING SPATIAL POLYGONS FOR EFFICIENT SPATIAL REGION QUERIES

Abstract. Spatial region queries are more and more widely used in web-based applications. Mechanisms to provide efficient query processing over geospatial data are essential. However, due to the massive geospatial data volume, heavy geometric computation, and high access concurrency, it is difficult to get response in real time. Spatial indexes are usually used in this situation. In this paper, based on k-d tree, we introduce a distributed KD-Tree (DKD-Tree) suitbable for polygon data, and a two-step query algorithm. The spatial index construction is recursive and iterative, and the query is an in memory process. Both the index and query methods can be processed in parallel, and are implemented based on HDFS, Spark and Redis. Experiments on a large volume of Remote Sensing images metadata have been carried out, and the advantages of our method are investigated by comparing with spatial region queries executed on PostgreSQL and PostGIS. Results show that our approach not only greatly improves the efficiency of spatial region query, but also has good scalability, Moreover, the two-step spatial range query algorithm can also save cluster resources to support a large number of concurrent queries. Therefore, this method is very useful when building large geographic information systems.
Text compaction for display on very small screens

Very small screens, such as the LCD displays on cellular telephones, pose unique problems for the display of textual messages. This paper presents a collection of techniques used to compact email text for display on mobile devices. These techniques range from simple string manipulations to more sophisticated linguistic processing. The techniques have been implemented in a commercial product for four languages: English, French, German and Spanish.
A Configurable Security Subsystem in a Middleware Framework for Embedded Systems

Computer and network security is becoming increasingly important as both large systems and, increasingly small, embedded systems are networked. Middleware frameworks aid the system developer who must interconnect individual systems into larger interconnected, distributed systems. However, there exist very few middleware frameworks that have been designed for use within the embedded systems, which constitute the vast majority of CPUs produced each year, and none oer the range of security mechanisms required by the wide range of embedded system applications. This paper describes MicroQoSCORBA, a highly configurable middleware framework for embedded systems, and its security subsystem. It first presents an analysis of security requirements for embedded applications and what can and should be done in middleware. It then presents the design of MicroQoSCORBA’s security subsystem and the wide range of mechanisms it supports. Experimental results for these mechanisms are presented for two dierent embedded systems and one desktop computer that collectively represent a wide range of computational capabilities.
Diurnal dynamics of stomatal conductance and leaf temperature of grapevines (Vitis vinifera L.) in response to daily climatic variables.

Few studies examined the stomatal conductance (gs) characteristics of grape- vines with an emphasis on daily climatic responses. In the present study, diurnal meas- urements on leaf temperature and gs of three grapevine cultivars (Alphonse Lavallee, Crimson Seedless and Italia) were carried out. The leaf temperature values for the culti- vars at 08:30 were 25.0 ±1°C and it increased to a maximum value between 12:00 and 14:50 p.m. After an almost steady course, it decreased along with the decrease in ambient temperature. The gs values increased from morning (08:30 a.m.) to mid-morning (10:30 a.m.) for all the cultivars. After reaching a peak level at mid-morning, the gs de- creased gradually from the mid-morning throughout the afternoon. In the morning, the highest and the least gs values were obtained from Italia (232 mmol H2O m -2 s -1 ) and Crimson Seedless (149.6 mmol H2O m -2 s -1 ) cultivars. At around 10:30, the gs for Italia, Crimson Seedless and Alphonse Lavallee were at the highest levels with their valus 287.7, 262.1 and 242.0 mmol H2O m -2 s -1 , respectively. The last measurements on gs at around 16:10 varied from to 96.7 (Italia) to 112.0 mmol H2O m -2 s -1 (Alphonse Lavallee). During the daily time course, the gs depended mainly on irradiance. Tleaf showed a strong rela- tionship with Tair for all the cultivars. There was a strong, but negative correlation be- tween leaf temperature and air humidity for all the cultivars.
Salinity-induced mixed and barrier layers in the southwestern tropical Atlantic Ocean off the northeast of Brazil

Abstract. High-resolution hydrographic observations of temperature and salinity are used to analyze the formation and distribution of isothermal depth ( Z T ), mixed depth ( Z M ) and barrier layer thickness (BLT) in a section of the southwestern Atlantic (0°30´ N–14°00´ S; 31°24´–41°48´ W), adjacent to the northeastern Brazilian coast. Analyzed data consists of 279 CTD casts acquired during two cruises under the Brazilian REVIZEE Program. One occurred in late austral winter (August–October 1995) and another in austral summer (January–April 1997). Oceanic observations are compared to numerical modeling results obtained from the French Mercator-Coriolis Program. Results indicate that the intrusion of subtropical Salinity Maximum Waters (SMW) is the major process contributing to the seasonal barrier layer formation. These waters are brought by the South Equatorial Current (SEC), from the subtropical region, into the western tropical Atlantic boundary. During late austral winter southeastern trade winds are more intense and ITCZ precipitations induce lower surface salinity values near the equator. During this period a 5–90 m thick BLT (median = 15 m) is observed and BLT > 30 m is restricted to latitudes higher than 8° S, where the intrusion of salty waters between 8°–12.3° S creates shallow mixed layers over deep ( Z T ≥ 90 m) isothermal layers. During austral summer, shallow isothermal and mixed layers prevail, when northeasterly winds are predominant and evaporation overcomes precipitation, causing saltier waters at the surface/subsurface layers. During that period observed BLT varies from 5 to 70 m and presents thicker median value of 35 m, when comparing to the winter. Furthermore, BLT ≥ 30 m is observed not only in the southernmost part of the study area, as verified during late winter, but in the latitude range 2°–14° S, where near-surface salty waters are transported westward by the SEC flow. These results indicate that the inclusion of salinity dynamics and its variability are necessary for studying mixed and barrier layer behaviors in the tropical Atlantic, where ocean-atmosphere coupling is known to be stronger.
Maintaining consistent traceability in high-precision isotope measurements of CO 2 : a way to verify atmospheric trends of δ 13 C and δ 18 O

Abstract. Maintaining consistent traceability of high-precision measurements of CO2 isotopes is critical in order to obtain accurate atmospheric trends of δ13C and δ18O (in CO2). Although a number of laboratories/organizations around the world have been conducting baseline measurements of atmospheric CO2 isotopes for several decades, reports on the traceability and maintenance are rare. In this paper, a principle and an approach for maintaining consistent traceability in high-precision isotope measurements (δ13C and δ18O) of atmospheric CO2 are described. The concept of Big Delta is introduced and its role in maintaining traceability of the isotope measurements is described and discussed extensively. The uncertainties of the traceability have been estimated based on annual calibration records over the last 10 yr. The overall uncertainties of CO2 isotope measurements for individual ambient samples analyzed by the program at Environment Canada have been estimated (excluding these associated with the sampling). The values are 0.02 and 0.05‰ in δ13C and δ18O, respectively, which are close to the World Meteorological Organization (WMO) targets for data compatibility. The annual rates of change in δ13C and δ18O of the primary anchor (which links the flask measurements back to the VPDB-CO2 scale) are close to zero (−0.0016 ± 0.0012‰, and −0.006 ± 0.003‰ per year, respectively) over a period of 10 yr (2001–2011). The average annual changes of δ13C and δ18O in air CO2 at Alert GAW station over the period from 1999 to 2010 have been evaluated and confirmed; they are −0.025 ± 0.003‰ and 0.000 ± 0.010‰, respectively. The results are consistent with a continuous contribution of fossil fuel CO2 to the atmosphere, having a trend toward more negative in δ13C, whereas the lack of change in δ18O likely reflects the influence from the global hydrologic cycle. The total change of δ13C and δ18O during this period is ~0.27‰ and ~0.00‰, respectively. Finally, the challenges and recommendations as strategies to maintain a consistent traceability are described.

Reviving fiscal policy in Europe: towards an implementation of the golden rule of public investment

The implementation of a golden rule of public investment as a necessary institutional reform and an important step aimed at overcoming the constraints imposed by the new European Economic Governance are proposed. The rule is widely accepted in traditional public finance and can deliver both intergenerational fairness as well as more growth and employment. The golden rule would exempt public (net) investment suitably defined from the relevant deficit targets of both the preventative and the corrective arms of the Stability and Growth Pact as well as the Fiscal Compact. That way, fiscal policy would be upgraded and would receive more room for manoeuvre and public investment as a particularly growth-enhancing public expenditure category would be strengthened. Different definitions are discussed and a pragmatic definition based on the national accounts with some modifications will be proposed. The standard reservations against a golden rule are critically assessed and mostly discarded. Although a proper implementation would need some time, this should not be an excuse for not using pragmatic short-term solutions that are readily available at the European level.
