Data allocation in distributed database systems

The problem of allocating the data of a database to the sites of a communication network is investigated. This problem deviates from the well-known file allocation problem in several aspects. First, the objects to be allocated are not known a priori; second, these objects are accessed by schedules that contain transmissions between objects to produce the result. A model that makes it possible to compare the cost of allocations is presented; the cost can be computed for different cost functions and for processing schedules produced by arbitrary query processing algorithms. For minimizing the total transmission cost, a method is proposed to determine the fragments to be allocated from the relations in the conceptual schema and the queries and updates executed by the users. For the same cost function, the complexity of the data allocation problem is investigated. Methods for obtaining optimal and heuristic solutions under various ways of computing the cost of an allocation are presented and compared. Two different approaches to the allocation management problem are presented and their merits are discussed.
Why increased extreme precipitation under climate change negatively affects water security

Abstract. An increase in extreme precipitation is projected for many areas worldwide in the coming decades. To assess the impact of increased precipitation intensity on water security, we applied a regional-scale hydrological and soil erosion model, forced with regional climate model projections. We specifically considered the impact of climate change on the distribution of water between soil (green water) and surface water (blue water) compartments. We show that an increase in precipitation intensity leads to a redistribution of water within the catchment, where water storage in soil decreases and reservoir inflow increases. This affects plant water stress and the potential of rainfed versus irrigated agriculture, and increases dependency on reservoir storage, which is potentially threatened by increased soil erosion. This study demonstrates the crucial importance of accounting for the fact that increased precipitation intensity leads to water redistribution between green and blue water, increased soil erosion, and reduced water security. Ultimately, this has implications for design of climate change adaptation measures, which should aim to increase the water holding capacity of the soil (green water) and to maintain the storage capacity of reservoirs (blue water), benefiting rainfed and irrigated agriculture.

Growth response and tibia bone characteristics in broilers fed diets containing kaolin, bentonite and zeolite.

This study was conducted to evaluate the effectiveness of adding silicate mineral in feed on tibia bone characteristics and tibia, meat, as well as on faecal ash content in broilers. Four hundred and forty eight one-day-old broiler chicks were reared using a completely randomized design with seven treatments (diets containing 0, 1.5, or 3% of kaolin, bentonite, or zeolite) having four replicates of 16 birds each for 42 days. Body weight gain was significantly (P 0.05) differences in tibia length, diaphysis diameter, medullary canal diameter, relative bone weight, tibia and meat dry mater, blood phosphorus, and tibia phosphorus among dietary treatments and control. In conclusion it seems that inclusion of a higher level (3%) of silicate mineral in diets is more effective than the lower level (1.5%) in improving tibia bone characteristics and ash in broiler chickens.
Continuous hydrothermal flow synthesis of Gd‐doped CeO2 (GDC) nanoparticles for inkjet printing of SOFC electrolytes

GdxCe1-xO2-d (GDC) nanoparticles were synthesized, using continuous hydrothermal flow synthesis. By varying the synthesis conditions, particle size and morphology could be tailored. Here, particle sizes between 6 and 40 nm with polyhedral or octahedral shape could be obtained. Gd0.2Ce0. 8O2-d nanoparticles were further processed into inks for inkjet printing. Despite the small particle size/large surface area, inks with excellent printing behavior were formulated. For proof-of-concept, thin GDC layers were printed on a) green NiO-GDC substrates, and on b) presintered NiO-YSZ substrates. While no dense layers could be obtained on the green NiO-GDC substrates, GDC nanoparticles printed on NiO-YSZ substrates formed a dense continuous layer after firing.
The Four Service Marketing Myths

Marketing was originally built on a goods-centered, manufacturing-based model of economic exchange developed during the Industrial Revolution. Since its beginning, marketing has been broadening its perspective to include the exchange of more than manufactured goods. The subdiscipline of service marketing has emerged to address much of this broadened perspective, but it is built on the same goods and manufacturing-based model. The influence of this model is evident in the prototypical characteristics that have been identified as distinguishing services from goods—intangibility, inseparability, heterogeneity, and perishability. The authors argue that these characteristics (a) do not distinguish services from goods, (b) only have meaning from a manufacturing perspective, and (c) imply inappropriate normative strategies. They suggest that advances made by service scholars can provide a foundation for a more service-dominant view of all exchange from which more appropriate normative strategies can be developed for all of marketing.
Metastable-Helium-4 source for cold atom experiments

This thesis presents a first step on the way towards a metastable helium BEC. This kind of experiment requires a high-flux source with a low peak velocity. In the scope of the Master’s Thesis, the source of metastable helium atoms was built and characterised. In addition, the atomic beam was collimated and deflected, in order to increase its intensity. The intensity of the metastable helium beam was measured to be approximately 1-8*10E14 atoms per steradian per second. At the same time the peak velocity ranged between 650-1050 m/s. The increase in the intensity of the atomic beam was achieved by a 2D collimation with laser light right after the skimmer. This enabled us to gain twenty-six-fold in the number of atoms per second per steradian.
Explicit Upper Bounds for Residues of Dedekind Zeta Functions and Values of L-Functions at s = 1, and Explicit Lower Bounds for Relative Class Numbers of CM-Fields

Abstract We provide the reader with a uniform approach for obtaining various useful explicit upper bounds on residues of Dedekind zeta functions of numbers fields and on absolute values of values at $s=1$ of $L$ -series associated with primitive characters on ray class groups of number fields. To make it quite clear to the reader how useful such bounds are when dealing with class number problems for CM-fields, we deduce an upper bound for the root discriminants of the normal CM-fields with (relative) class number one.
A study on relationship between abnormal accruals and future profitability: Evidence from Tehran Stock Exchange

This paper presents an empirical investigation to study the relationship between future profitability and abnormal accruals on selected firms from Tehran Stock Exchange (TSE). The study selects 223 firms from TSE market over the period 2007-2011. Using the regression analysis, the study shows there was no meaningful relationship between abnormal earnings and future profitability when the level of significance is five percent. There are also seven subhypotheses associated with the proposed study of this paper. The results indicate that while there were no meaningful relationship between firm size, capital expenditure, earnings quality and earning forecasted error on one side and future earnings, the study confirms a significance relationship between ratio of book value to equity as well as market leverage and future earnings.

RELATIONSHIP BETWEEN PARENTING STYLES AND ALCOHOL CONSUMPTION AMONG COLLEGE STUDENTS IN SEGI COLLEGE SUBANG JAYA, MALAYSIA

The main purpose of this study is to investigate the relationship between parenting styles and alcohol consumption among 150 college students (males = 72, females = 78) in Segi College Subang Jaya, Malaysia. The participants’ age is between 18 to 31. Parental Authority Questionnaire (PAQ) and Alcohol Use Disorder Identification Test (AUDIT) were employed in this study. The data was treated as normally distributed and therefore the Pearson product-moment correlation coefficient was used to test the correlation between parenting style and alcohol consumption. A significant relationship was found between authoritarian (r = 0.246, p < 0.05) and permissive (r = -0.426, p < 0.05) parenting style and alcohol consumption among the participants. The results of this investigation indicated that if the parents are authoritarian, college students consume more alcohol, but if the parents are permissive, college students are less likely to consume alcohol. There was a negative non-significant relationship between authoritative (r = -0.024, p < 0.05) and alcohol consumption among college students found in this study. This indicated that the increase in authoritative parenting style do not significantly relate to the decrease in alcohol consumption among college students.
Air Pollution and Premature Mortality in Rapidly Growing Economies: Evidence from Santiago, Chile

This paper looks at the effects of air pollution on premature mortality by using a municipality-week panel data of mortality and particulate matter of diameter of 10 micrometers or less (PM10) for Santiago, Chile. We use exogenous variation induced by thermal inversions and a spatial mapping method (Kriging) to reduce the attenuation bias from the measurement error of imputed municipalitylevel air pollution data. We find significant effects of PM10 on infant mortality and large effects for premature mortality (both neonatal and infant mortality) for respiratory and cardiovascular causes.
Proton MR Spectroscopy Provides Relevant Prognostic Information in High-Grade Astrocytomas

The range of survival in patients with high-grade astrocytomas varies and cannot be explained based only on histology. We now know that this variation is accounted for in many tumors by their genetic differences. Here, the authors tried to assess the predictive value of single-voxel proton MR spectroscopy in high-grade astrocytomas and evaluated 180 patients using both short and long TE MRS. They then divided the patients into 2 simple groups: those above median survival were designated as having good survival and those below it as having poor survival (nearly equal numbers in both groups). For analysis, they chose 2 locations in each long and short TE study with the former corresponding to lipid resonances and the latter to lipids and possibly sugars (as well as other less well-defined metabolites). They also acknowledged some possible contributions of lactate, which is known to precede neovascular activity in high-grade astrocytoma. Basically, higher lipids and depletion of glucose indicated a poorer prognosis as both are related to more aggressive behavior. Another important observation was that even treated tumors showed the same spectroscopic behavior and a corresponding poor prognosis. BACKGROUND AND PURPOSE: There is a large range of survival times in patients with HGA that can only be partially explained by histologic grade and clinical aspects. This study aims to retrospectively assess the predictive value of single-voxel 1H-MRS regarding survival in HGA. MATERIALS AND METHODS: Pretreatment 1H-MRS in 187 patients with HGA produced 180 spectra at STE (30 ms) and 182 at LTE (136 ms). Patients were dichotomized into 2 groups according to survival better or worse than the median. The spectra of the 2 groups were compared using the Mann-Whitney U test. The points on the spectrum with the most significant differences were selected for discriminating patients with good and poor prognosis. Thresholds were defined with ROC curves, and survival was analyzed by using the Kaplan-Meier method and the Cox proportional hazards model. RESULTS: Four points on the spectrum showed the most significant differences: 0.98 and 3.67 ppm at STE; and 0.98 and 1.25 ppm at LTE (P between <.001 and .011). These points were useful for stratifying 2 prognostic groups (P between <.001 and .003, Kaplan-Meier). The Cox forward stepwise model selected 3 spectroscopic variables: the intensity values of the points 3.67 ppm at STE (hazard ratio, 2.132; 95% CI, 1.504–3.023), 0.98 ppm at LTE (hazard ratio, 0.499; 95% CI, 0.339–0.736), and 1.25 ppm at LTE (hazard ratio, 0.574; 95% CI, 0.368–0.897). CONCLUSIONS: 1H-MRS is of value in predicting the length of survival in patients with HGA and could be used to stratify prognostic groups.
TREC to WHERE? Transdisciplinary Research on Energetics and Cancer

When information is exchanged across disciplinary boundaries, resources are shared, and discipline-specific approaches are altered to achieve a common scientific goal, we create a new intellectual space for transdisciplinary research. This approach, fostered heavily by multiple NCI-funded initiatives, has the potential to forge new understanding of major public health issues. By breaking down disciplinary barriers, we work toward making real, meaningful, and lasting forward motion in addressing key public health issues. One of the transdisciplinary initiatives of the NCI is TREC: Transdisciplinary Research on Energetics and Cancer. In this article, we review the goals and scope of TREC, as well as the ways in which the initiative promotes transdisciplinary science. A particular focus is on multiple examples of the most unique aspect of the initiative: the funding of developmental projects across multiple TREC centers, toward the goal of incubating high-risk science that has the potential to translate into major leaps forward in understanding energetics in cancer. As we enter an era of greater focus on investigator-initiated science, new approaches may be needed to ensure that the peer review process is not solely organized along disciplinary lines. Inclusion of expertise regarding transdisciplinarity, as well as representation from multiple scientific disciplines within a panel, may allow transdisciplinary research to receive an educated hearing. The body of researchers trained to work in a transdisciplinary research space is ideally suited to address these challenges. Clin Cancer Res; 22(7); 1565–71. ©2016 AACR.
FIRST RECORD OF FUSARIUM NIVALE (FR.) CES. ASSOCIATED WITH MANGO MALFORMATION DISEASE (MMD) IN PAKISTAN

During a survey of mango plantations in Sindh for investigating the association of fungi with mango malformation disease (MMD), six fungal species viz., Fusarium nivale (Fr.) Ces, F. oxysporium, F. moniliforme, F. semitectum, Alternari alternata and Aspergillus niger were isolated and identified on the basis of their colony characteristics and conidial morphology. F. nivale (Fr.) Ces. , was predominantly isolated from malformed tissues of infected inflorescence; it produced white colonies and some discoloration of the agar medium was noticed around the growing mycelium. This is the first record of Fusarium nivale (Fr.) Ces. , from Pakistan and also the first report of its association with mango malformation in Sindh, Pakistan.
Studies on the role of gene-environment interaction in the pathogenesis of schizophrenia using a genetic animal model

AbstractGenetic factors and early adverse environmental events interact to contribute to thepathogenesis of schizophrenia. Here, we investigated if immune-activation duringdevelopment interacts with a susceptibility gene to produce schizophrenia-relatedphenotypes. We injected mice with a loss of function mutation in dysbindin-1, aschizophrenia-risk gene and controls with either Polyinosinic:polycytidylic acid (PolyI:C), a viral mimic or saline, at postnatal days (PD)5,6 and 7. At PD60, possible geneenvironment(GxE) interaction was studied using tests of behaviours relevant toschizophrenia as well as examination of postnatal neurogenesis. Our data showed asignificant effect of genotype on spontaneous locomotion as dysbindin-1 homozygousmice displayed increased locomotor activity. Further, we observed a significant effect ofgenotype as a decrease in the number of newborn cells in the glomerular layer of theolfactory bulb (OB). Analyses of the data did not reveal an interactive effect betweendysbindin-1 and Poly I:C exposure as far as spontaneous locomotion, pre-pulse inhibitionof the acoustic startle, novel object recognition memory, elevated plus maze, fearmemory, the number of newborn cells in the dentate gyrus and granular cell layer of theolfactory bulb are concerned. These preliminary results demonstrate lack of an interactiveeffect between this schizophrenia candidate gene and this viral mimic at neonatal periodson selected behavioural and neurobiological measures. Further investigation usingdifferent doses of the immune activator and/or different timing of treatment are needed tofully test GxE hypothesis. %%%%RESUMEL'interaction entre les genes et les incidents d'adversites environnementales tot dans la viecontribuent a la pathogenese de la schizophrenie.

An Analysis of Values Literacy and Internalisation in Students Commencing High School: A Pilot Study

This mixed methods pilot study investigated the impact of values education on Year Seven students in three Christian K-12 schools in Australia. Participants were surveyed to determine their knowledge, understanding, and internalisation of the Nine Core Values for Australian Schooling. Further, random selections of students from two schools participated in three focus groups that discussed scenarios describing value-laden interactions. The study found that Year Seven students had a varied knowledge and understanding of the Nine Core Values for Australian Schooling that appeared independent of background variables. The study also found that the participants generally had sound levels of internalisation of values, but that the levels of internalisation among girls exceeded that among boys. Further, the study found no relationship between the knowledge of values and the internalisation of values.
Digital models perfection for solving problems of IPS/UPS systemic reliability

SUMMARY The high level of the systemic reliability of IPS/UPS synchronous zone is provided due to continuous scientific and technical support of its development and day-to-day operation. As one of the basic research tools the digital models of the whole power system and its separate fragments are applied. At the same time the principle of the common infobase is applied during various digital models creation. With the advent of new microprocessor regulating devices in the UPS of Russia, implementing complex control laws, the available digital models of electric power systems became inadequate from the point of view of providing both a quantitative assessment of stability margins , and a qualitative coincidence of the history of electromechan ical transients to a reality after normative perturbations. This has led to the necessity of perfection of digital models of complex power systems by including in their structure detailed microprocessor control devices models. In the modern dynamic models the most detailed representation is used for the automatic voltage (excitation) controllers (AVR) and power system stabilizers (PSS). Digital modeling of the AVRs and PSSs is carried out using their full mathematical description. For the creation of digital models of modern domestic AVRs the EUROSTAG and PSS/E software are used. In the environment of this software the full digital models of semi-conducto r, analog-digita l and digital excitation controllers were realized. The adjustment and verification of AVR digital models is made by the comparison of the response characteristics of regulating channels with the data of tests of industrial samples or the data provided by the AVR producers. Response characteristics of the microprocessor AVR are distinguished by their high stability, therefore it is sufficient for them to verify the typical model. After that the model can be applied for any generator for the sampling of the adjustment of AVR channels. All semi-conductor excitation controllers have specific features, therefore their models for each concrete installation requires additional tuning, which is carried out on the base of full-scale test data. Example of verification of the model of analogue excitation controller and PSS of the North-West TPP is given in the report. Aforementioned approaches guarantee the reliability of operational computations with the use of digital models and allow to use them for solving various problems, such as the analysis of emergencies and development of recommendations of their prevention, examinations of various projects regarding maintenance of transient and small-signal stability, adjustment of the power system stabilizers on functioning installations, analysis of low-frequency oscillations, sampling of adjustments of counteremergency automatons, etc. Examples of practical use of IPS/UPS reference digital model and its separate fragments are given in the report.
