Synthesis of zeolite/hydrous metal oxide composites from coal fly ash as efficient adsorbents for removal of methylene blue from water

Zeolites are useful crystalline aluminosilicate minerals, and zeolite synthesis from coal fly ash (ZFA) has been investigated widely to recycle solid waste. This synthesis process produces waste alkaline solution as a by product. To date, research has focused mainly on ZFA synthesis and use; the problematic waste alkaline solution has rarely been addressed. In this study, we developed two composites of zeolite/hydrous iron oxide (ZFA/HIO) and zeolite/hydrous zirconia (ZFA/HZ) by adding, after zeolite synthesis, a step in which waste alkaline solutions are neutralized with an iron or zirconium salt. The composites were characterized by X ray fluorescence, X ray diffractometry, scanning electron microscopy, acid base neutralizing ability, specific surface area and pore size distribution, and their performance as adsorbents for the removal of methylene blue (MB) from water was investigated. MB adsorption by ZFA/HIO and ZFA/HZ was much higher than that by ZFA, and increased with increasing pH. This behavior was explained by the increased variable charge on the metal oxides. The adsorption was rapid, and nearly complete removal could be achieved at a sufficiently high dose. Material heating resulted in a decrease in pH and adsorption, but heating with pH adjustment could regenerate adsorbents for repeated use in MB removal. Zeolite/hydrous metal oxide synthesis from coal fly ash was environmentally friendly and products exhibit a high potential as reusable adsorbents for MB removal from water.
Trace element composition of silicate inclusions in sub lithospheric diamonds from the Juina 5 kimberlite: Evidence for diamond growth from slab melts

The trace element compositions of inclusions in sub lithospheric diamonds from the Juina 5 kimberlite, Brazil, are presented. Literature data for mineral/melt partition coefficients were collated, refitted and employed to interpret inclusion compositions. As part of this process an updated empirical model for predicting the partitioning behaviour of trivalent cations for garnet melt equilibrium calibrated using data from 73 garnet melt pairs is presented. High levels of trace element enrichment in inclusions interpreted as former calcium silicate perovskite and majoritic garnet preclude their origin as fragments of an ambient deep mantle assemblage. Inclusions believed to represent former bridgmanite minerals also display a modest degree of enrichment relative to mantle phases. The trace element compositions of 'NAL' and 'CF phase' minerals are also reported. Negative Eu, Ce, and Y/Ho anomalies alongside depletions of Sr, Hf and Zr in many inclusions are suggestive of formation from a low degree carbonatitic melt of subducted oceanic crust. Observed enrichments in garnet and 'calcium perovskite' inclusions limit depths of melting to less than 600 km, prior to calcium perovskite saturation in subducting assemblages. Less enriched inclusions in sub lithospheric diamonds from other global localities may represent deeper diamond formation. Modelled source rock compositions that are capable of producing melts in equilibrium with Juina 5 'calcium perovskite' and majorite inclusions are consistent with subducted MORB. Global majorite inclusion compositions suggest a common process is responsible for the formation of many superdeep diamonds, irrespective of geographic locality. Global transition zone inclusion compositions are reproduced by fractional crystallisation from a single parent melt, suggesting that they record the crystallisation sequence and melt evolution during this interaction of slab melts with ambient mantle. All observations are consistent with the previous hypothesis that many superdeep diamonds are created as slab derived carbonatites interact with peridotitic mantle in the transition zone.
SparRec: An effective matrix completion framework of missing data imputation for GWAS
Venue: Scientific reports

Genome wide association studies present computational challenges for missing data imputation, while the advances of genotype technologies are generating datasets of large sample sizes with sample sets genotyped on multiple SNP chips. We present a new framework SparRec (Sparse Recovery) for imputation, with the following properties: (1) The optimization models of SparRec, based on low rank and low number of co clusters of matrices, are different from current statistics methods. While our low rank matrix completion (LRMC) model is similar to Mendel Impute, our matrix co clustering factorization (MCCF) model is completely new. (2) SparRec, as other matrix completion methods, is flexible to be applied to missing data imputation for large meta analysis with different cohorts genotyped on different sets of SNPs, even when there is no reference panel. This kind of meta analysis is very challenging for current statistics based methods. (3) SparRec has consistent performance and achieves high recovery accuracy even when the missing data rate is as high as 90% Compared with Mendel Impute, our low rank based method achieves similar accuracy and efficiency, while the co clustering based method has advantages in running time. The testing results show that SparRec has significant advantages and competitive performance over other state of the art existing statistics methods including Beagle and fastPhase.
Exploring the influential factors in continuance usage of mobile social Apps: Satisfaction, habit, and customer value perspectives
Venue: Telematics Informatics

Mobile social Apps have exponentially changed the way people communicate.Three antecedents (utilitarian, hedonic, and social perspectives) were examined.User satisfaction and habitual use were successfully explained by all antecedents.Continuance usage was driven by satisfaction, habitual use, and two other factors.The mediation effects of satisfaction and habitual use were found. The emergence of mobile application software (App) has explosively grown in conjunction with the worldwide use of smartphones in recent years. Among numerous categories of mobile Apps, social Apps were one of those with the greatest growth in 2013. Despite abundant research on users' behavior intention of mobile App usage, few studies have focused on investigating key determinants of users' continuance intention regarding social Apps. To fill this gap, we integrated customer value perspectives to explore the influential factors in the continuance intention of social App use. Moreover, users' satisfaction and habit from both the marketing and psychology literature were also incorporated into the research model. A total of 378 valid questionnaires were collected by survey method, and structural equation modeling was employed in the subsequent data analysis. The results indicate that the continuance usage of social Apps is driven by users' satisfaction, tight connection with others, and hedonic motivation to use the Apps. In addition, full mediation effects of satisfaction and habit were found between perceived usefulness and intention to continue use. These findings extend our understanding of users' continuance intention in the context of social Apps. Discussion and implications are provided.
Creating Enduring Customer Value

One of the most important tasks in marketing is to create and communicate value to customers to drive their satisfaction, loyalty, and profitability. In this study, the authors assume that customer value is a dual concept. First, in order to be successful, firms (and the marketing function) have to create perceived value for customers. Toward that end, marketers have to measure customer perceived value and have to provide customer perceptions of value through marketing mix elements. Second, customers in return give value through multiple forms of engagement (customer lifetime value, in the widest sense) for the organization. Therefore, marketers need to measure and manage this value of the customer(s) to the firm and have to incorporate this aspect into real time marketing decisions. The authors integrate and synthesize existing findings, show the best practices of implementation, and highlight future research avenues.
Creatividad e inteligencias multiples segun el genero en alumnado de Educacion Primaria

The early years of schooling are considered fundamental for an optimal development of creativity and multiple intelligences in both boys and girls. Using theoretical frameworks that explain both variables, the aim of this study is to analyze the significant differences in creativity and multiple intelligences between First Grade students. The sample consisted of 60 students (boys 31, girls 29) aged between 6 and 7 years belonging to a public school in Zaragoza. The instruments used were the Torrance Creative Thinking Test and the questionnaire for teachers to diagnose Multiple Intelligences in Primary. The results showed significant differences in creativity, the girls obtaining higher scores. Regarding multiple intelligences, interpersonal intelligence which that which obtained higher scores in both sexes. Concurrently, musical intelligence scored lowest in boys and girls, being the only one that showed significant differences. These findings are discussed arguing the need for an intervention program that strengthens the development of creativity and musical intelligence in both sexes by way of the other intelligences and teamwork. This can mean cross curricular learning to optimize student development in a holistic fashion.
Design Patterns and Extensibility of REST API for Networking Applications
Venue: IEEE Transactions on Network and Service Management

REST architectural style has become a prevalent choice for distributed resources, such as the northbound API of software defined networking (SDN) As services often undergo frequent changes and updates, the corresponding REST APIs need to change and update accordingly. To allow REST APIs to change and evolve without breaking its clients, a REST API can be designed to facilitate hypertext driven navigation and its related mechanisms to deal with structure changes in the API. This paper addresses the issues in hypertext driven navigation in REST APIs from three aspects. First, we present REST Chart, a Petri Net based REST service description framework and language to design extensible REST APIs, and it is applied to cope with the rapid evolution of SDN northbound APIs. Second, we describe some important design patterns, such as backtracking and generator, within the REST Chart framework to navigate through large scale APIs in the RESTful architecture. Third, we present a client side differential cache mechanism to reduce the overhead of hypertext driven navigation, addressing a major issue that affects the application of REST API. The proposed approach is applied to applications in SDN, which is integrated with a generalized SDN controller, SOX. The benefits of the proposed approach are verified in different conditions. Experimental results on SDN applications show that on average, the proposed cache mechanism reduces the overhead of using the hypertext driven REST API by 66% while fully maintaining the desired flexibility and extensibility of the REST API.
Diverse Orthorrhaphan Flies (Insecta: Diptera: Brachycera) in Amber From the Cretaceous of Myanmar: Brachycera in Cretaceous Amber, Part VII
Venue: Bulletin of the American Museum of Natural History

A remarkable diversity of new nonempidoid orthorrhaphan flies from the mid Cretaceous of Myanmar (Late Albian Early Cenomanian, ca. 99 Ma) is presented, including 28 species (all but one new) in 22 genera (13 new) and at least 12 families. Two families are new; three genera are unplaced in Tabanomorpha and one unplaced within Brachycera. Comparisons are presented between the amber taxa and extensive lithified taxa from the Jurassic and Cretaceous of eastern Laurasia.  A new species of Zhangsolvidae has color patterns and body shape that apparently mimic Vespidae or other stinging aculeate wasps. Diverse new Xylomyidae and Stratiomyidae are described, the latter with male terminalia preserved in detail. In Tabanomorpha: The genus Athericites Mostovski et al. is synonymized with Palaepangonius Ren, and a new species of Galloatherix Nel is described in which the female proboscis is much longer than that of the male. All three genera were attributed to Athericidae, but the amber species reveal they are more basal tabanomorphs. Described are a new genus of stem group Tabanoidea and a new species of Cratotabanus Martins Neto and Kucero Santos (Tabanidae) previously known from the Cretaceous of Brazil and New Jersey. In Nemestrinoidea: Three species of Hirmoneura Meigen are the first Nemestrinidae known from amber; one species has long cerci typical of Recent species of the genus. A new species of the Mesozoic family Rhagionemestriidae reveals this family is closely related to Acroceridae, not Xylophagidae as previously proposed.  A new species of Tethepomyiidae is described, the family known only in Cretaceous amber from New Jersey, Spain, and Myanmar.  Three new species and genera of Bombyliidae are described, two of them with abdominal setal "baskets" distinctive to females of higher bombyliids. A fourth new asiloid genus is a probable stem group bombyliid. The recently described Pseudorhagio Zhang et al. is transferred from Tabanomorpha to Bombyliidae. The male of a new species of Burmapsilocephala Gaimari and Mostovski (Apsilocephalidae) has terminalia very similar to that of Evocoa (Evocoidae: Recent, Chile) corroborating close relationship of the two families. In Families incertae sedis: A new species of Hilarimorphites Grimaldi and Cumming (Apystomyiidae) is described, the family known only in New Jersey and Burmese amber and the Recent fauna of California, and a sister group to either Cyclorrhapha or Eremoneura. Mysteromyiidae and Eucaudomyiidae, new families, are described, based on highly modified species with vestigial mouthparts, reduced venation, and unique specializations. Discussion is presented on some morphological features in fossil and Recent Brachycera that have apparent phylogenetic significance but are rarely discussed. This study adds further data to the phenotypic diversity, geological history, and biogeography of a major radiation.
Strategic Planning and Management in Local Government in Norway: Status after Three Decades

Strategic planning and management was introduced in the public sector more than three decades ago and has become a core component in many new public management reforms. Although strategy has been widely adopted in the public sector, the knowledge base regarding its practices and its impacts remains scarce, particularly outside Anglo American countries. This article replicates an American and British survey by analysing the adoption and impacts of strategic planning and management in Norwegian municipalities. The results show that, in 2012, a majority of the Norwegian municipalities used strategic planning and management, and that the respondents viewed the impact positively overall. Municipalities that had chosen the strategic stance of prospector and had financial resources from positive net operating results margin adopted strategic planning and management more than other municipalities. Municipalities with a high degree of strategic management and high stakeholder involvement had better perceived impacts of strategic planning than other municipalities.
DNA Sequence Alignment during Homologous Recombination*
Venue: The Journal of Biological Chemistry

Homologous recombination allows for the regulated exchange of genetic information between two different DNA molecules of identical or nearly identical sequence composition, and is a major pathway for the repair of double stranded DNA breaks. A key facet of homologous recombination is the ability of recombination proteins to perfectly align the damaged DNA with homologous sequence located elsewhere in the genome. This reaction is referred to as the homology search and is akin to the target searches conducted by many different DNA binding proteins. Here I briefly highlight early investigations into the homology search mechanism, and then describe more recent research. Based on these studies, I summarize a model that includes a combination of intersegmental transfer, short distance one dimensional sliding, and length specific microhomology recognition to efficiently align DNA sequences during the homology search. I also suggest some future directions to help further our understanding of the homology search. Where appropriate, I direct the reader to other recent reviews describing various issues related to homologous recombination.
The SMEM Seeding Acceleration for DNA Sequence Alignment
Venue: 2016 IEEE 24th Annual International Symposium on Field Programmable Custom Computing Machines (FCCM)

The advance of next generation sequencing technology has dramatically reduced the cost of genome sequencing. However, processing and analyzing huge amounts of data collected from sequencers introduces significant computation challenges, these have become the bottleneck in many research and clinical applications. For such applications, read alignment is usually one of the most compute intensive steps. Billions of reads generated from the sequencer need to be aligned to the long reference genome. Recent state of the art software read aligners follow the seed andextend model. In this paper we focus on accelerating the first seeding stage, which generates the seeds using the supermaximal exact match (SMEM) seeding algorithm. The two main challenges for accelerating this process are 1) how to process a huge number of short reads with high throughput, and 2) how to hide the frequent and long random memory access when we try to fetch the value of the reference genome. In this paper, we propose a scalable array based architecture, which is composed by many processing engines (PEs) to process large amounts of data simultaneously for the demand of high throughput. Furthermore, we provide a tight software/hardware integration that realizes the proposed architecture on the Intel Altera HARP system. With a 16 PE accelerator engine, we accelerate the SMEM algorithm by 4x, and the overall SMEM seeding stage by 26% when compared with 16 thread CPU execution. We further analyze the performance bottleneck of the design due to extensive DRAM accesses and discuss the possible improvements that are worthwhile to be explored in the future.
Analysing Structured Scholarly Data Embedded in Web Pages

Web pages increasingly embed structured data in the form of microdata, microformats and RDFa. Through efforts such as schema.org, such embedded markup have become prevalent, with current studies estimating an adoption by about 26% of all web pages. Similar to the early adoption of Linked Data principles by publishers, libraries and other providers of bibliographic data, such organisations have been among the early adopters, providing an unprecedented source of structured data about scholarly works. Such data, however, is fundamentally different from traditional Linked Data, by being very sparsely linked and consisting of a large amount of coreferences and redundant statements. So far, the scale and nature of embedded scholarly data on the Web has not been investigated. In this work, we provide a study on embedded scholarly data to answer research questions about the depth, syntactic and semantic characteristics and distribution of extracted data, thereby investigating challenges and opportunities for using embedded data as a structured knowledge graph of scholarly information.
The use of social media for engaging stakeholders in sustainability reporting

The purpose of this paper is to assess if online interaction through social media, particularly Facebook, Twitter, and YouTube, represents an effective stakeholder engagement mechanism in order to define the contents of social, environmental, or sustainability reporting (SESR)  After examining 332 worldwide sustainability reports for the year 2013, drawn up according to the guidelines provided by the Global Reporting Initiative, the authors conducted a content analysis on the Twitter, Facebook, and YouTube pages of the organisations who rely on these types of social media. This was done in order to assess the scope of interaction between the organisation and its stakeholders.  The authors found that a small number of organisations use social media to engage stakeholders as a means of defining the contents of SESR, and that the level of interaction is generally low. Rather than assuming a deliberative approach that is aimed at forging a democratic consensus.
Vaccination using melanoma cells treated with p19arf and interferon beta gene transfer in a mouse model: a novel combination for cancer immunotherapy
Venue: Cancer Immunology, Immunotherapy

Previously, we combined p19Arf (Cdkn2a, tumor suppressor protein) and interferon beta (IFN b, immunomodulatory cytokine) gene transfer in order to enhance cell death in a murine model of melanoma. Here, we present evidence of the immune response induced when B16 cells succumbing to death due to treatment with p19Arf and IFN b are applied in vaccine models. Use of dying cells for prophylactic vaccination was investigated, identifying conditions for tumor free survival. After combined p19Arf and IFN b treatment, we observed immune rejection at the vaccine site in immune competent and nude mice with normal NK activity, but not in NOD SCID and dexamethasone immunosuppressed mice (NK deficient) Combined treatment induced IL 15, ULBP1, FAS/APO1 and KILLER/DR5 expression, providing a mechanism for NK activation. Prophylactic vaccination protected against tumor challenge, where markedly delayed progression and leukocyte infiltration were observed. Analysis of primed lymphocytes revealed secretion of TH1 related cytokines and depletion protocols showed that both CD4+ and CD8+ T lymphocytes are necessary for immune protection. However, application of this prophylactic vaccine where cells were treated either with IFN b alone or combined with p19Arf conferred similar immune protection and cytokine activation, yet only the combination was associated with increased overall survival. In a therapeutic vaccine protocol, only the combination was associated with reduced tumor progression. Our results indicate that by harnessing cell death in an immunogenic context, our p19Arf and IFN b combination offers a clear advantage when both genes are included in the vaccine and warrants further development as a novel immunotherapy for melanoma.
