CLASSIFICATION OF NATURAL FLOW REGIMES IN THE EBRO BASIN (SPAIN) BY USING A WIDE RANGE OF HYDROLOGIC PARAMETERS
Authors: Alba Solans M. , LeRoy Poff N. 
Published: August 2012

ABSTRACTThis paper presents a classification of different natural flow regimes found in Ebro basin, one of the largest in the Mediterranean region. Determination of flow regimes was based on multivariate analyses using long‐term discharge series of unaltered flow data. Mean monthly discharges of the 30 ‘best’ flow series and a total of 52 flow series containing unaltered flow data were selected to represent baseline flow conditions for tributaries throughout the basin. Metrics representing magnitude, duration and frequency components of flow were used to identify hydrologic differences across the basin. A total of six natural flow regimes were identified in the Ebro Basin, using a Ward cluster method. The flow patterns identified and their spatial distribution largely corresponded with climatic zones previously reported for the Ebro Basin, with regime types ranging from pluvio‐oceanic in the western part of the basin to Mediterranean in the eastern region. Geologic characteristics of the catchment and altitude of headwaters were also found to play an important role in defining flow regime type. A 19‐hydrologic variable subset was used to explain main hydrologic differences among groups (such as magnitude and frequency of extreme flow conditions or magnitude and variance of average flow conditions). However, stepwise discriminant analysis was not able to identify consistent subsets of hydrologic variables that adequately identified the six natural flow regime types in this basin. Canonical discriminant analysis was useful to understand class separation and for the interpretation of results. Copyright © 2012 John Wiley & Sons, Ltd.
A Method for Evaluating Coke Hot Strength
Authors: Haapakangas Juho , Uusitalo Juha , Mattila Olli , Kokkonen Tommi , Porter David , Fabritius Timo 
Published: August 2012

AbstractThe strength of coke is of major importance for efficient blast furnace operation. There are only a few studies related to compressive coke hot strength, possibly due to experimental difficulties. In this work, it has been demonstrated that the Gleeble thermomechanical simulator is suitable for evaluating coke hot strength and offers many benefits compared to purpose‐built devices reported in the literature. This finding could open coke hot strength research to a wider number of scientists. The compressive hot strength of coke was evaluated at 1000 and 1600°C by testing 50 samples at both temperatures. The yield strength and ultimate strength of the coke were, respectively, 46 and 20% lower at 1600°C than 1000°C. Stress–strain curves showed that the coke was brittle at 1000°C but partially plastic at 1600°C. The significantly lower coke strength at 1600°C could help explain the smaller coke lump size found near the tuyere level in quenched blast furnaces.
Recent successes in coarse‐grained modeling of DNA
Authors: Potoyan Davit A. , Savelyev Alexey , Papoian Garegin A. 
Published: August 2012

AbstractThe growing interest in the DNA‐based mesoscale systems of biological and nonbiological nature has encouraged the computational molecular science community to develop coarse‐grained (CG) representationsof the DNA that will be simple enough to permit exhaustive simulations in a reasonable amount of time, yet complex enough to capture the essential physics at play. In the recent years, there have been some major developments in the DNA coarse‐graining area and several fairly sophisticated models are now available that faithfully reproduce key mechanical and chemical properties of the double‐ and single‐stranded DNA. However, there are still many challenges, which limit the applicability of the present models, and much has to be done yet to develop more reliable schemes which would have a predictive power beyond the target domain of the intrinsic parametrization. A development of robust, controllable, and transferrable CG DNA force fields will provide an invaluable tool for gaining physical insights into the molecular nature of complex DNA‐based nanoscale entities such as the chromatin, virus capsids, and DNA nanocomposites. In the present contribution, we provide an overview of the recent developments in the DNA coarse‐graining field. Our aim is to review the existing CG models of the double‐stranded DNA, where a small selection of models, which we believe provide avenues for promising future development, are discussed in some detail. © 2012 John Wiley & Sons, Ltd.This article is categorized under:

Visualization toolkit software
Authors: Wills Graham 
Published: August 2012

AbstractInformation visualization is a discipline that takes data as an input and produces visual representations of that data in a form that can be readily understood by people. The overall goal of a Visualization Toolkit is to provide a library that can be used by professionals to construct appropriate visualizations so as to allow their data to be understood and used in decision‐making. This article defines the major components of a visualization toolkit and provides details on how they can be implemented and the consequences and restrictions imposed by those decisions.WIREs Comput Stat2012 doi: 10.1002/wics.1224This article is categorized under:Algorithms and Computational Methods > Computer GraphicsStatistical and Graphical Methods of Data Analysis > Statistical Graphics and Visualization
Mining from protein–protein interactions
Authors: Mamitsuka Hiroshi 
Published: August 2012

AbstractProteins are important cellular molecules, and interacting protein pairs provide biologically important information, such as functional relationships. We focus on the problem of predicting physically interacting protein pairs. This is an important problem in biology, which has been actively investigated in the field of data mining and knowledge discovery. Our particular focus is on data‐mining‐based methods, and the objective of this review is to introduce these methods for data mining researchers from technical viewpoints. We categorize those methods into three types: pairwise data‐based, network‐based, and integrative approaches, each approach being described in a different section. The first section is further divided into five types, such as supervised learning, algorithmic approaches, and unsupervised learning. The second section is mainly on link prediction, which can be further divided into two types, and two subsections that cover topics related with protein interaction networks are further added. The final section provides a wide variety of methods in integrative approaches. © 2012 Wiley Periodicals, Inc.This article is categorized under:Algorithmic Development > Biological Data MiningApplication Areas > Industry Specific ApplicationsTechnologies > Machine Learning
Software mining and fault prediction
Authors: Catal Cagatay 
Published: August 2012

AbstractMining software repositories (MSRs) such as source control repositories, bug repositories, deployment logs, and code repositories provide useful patterns for practitioners. Instead of using these repositories as record‐keeping ones, we need to transform them into active repositories that can guide the decision processes inside the company. By MSRs with several data mining algorithms, effective software fault prediction models can be built and error‐prone modules can be detected prior to the testing phase. We discuss numerous real‐world challenges in building accurate fault prediction models and present some solutions to these challenges. © 2012 Wiley Periodicals, Inc.This article is categorized under:

The Silicides M4Si4 with M = Na, K, Rb, Cs, and Ba2Si4 – NMR Spectroscopy and Quantum Mechanical Calculations
Authors: Goebel Thorsten , Ormeci Alim , Pecher Oliver , Haarmann Frank 
Published: August 2012

AbstractThe Zintl phases M4Si4 with M = Na, K, Rb, Cs, and Ba2Si4 feature a common structural unit, the Si44– anion. The coordination of the anions by the cations varies significantly. This allows a systematic investigation of the bonding situation of the anions by 29Si NMR spectroscopy. The compounds were characterized by powder X‐ray diffraction, differential thermal analysis, magnetic susceptibility measurements, 23Na, 29Si, 87Rb, 133Cs NMR spectroscopy, and quantum mechanical calculation of the NMR coupling parameter. The chemical bonding was investigated by quantum mechanical calculations of the electron localizability indicator (ELI). Synthesis of the compounds results for all of them in single phase material. A systematic increase of the isotropic 29Si NMR signal shift with increasing atomic number of the cations is observed by NMR experiments and quantum mechanical calculation of the NMR coupling parameter. The agreement of experimental and theoretical results is very good allowing an unambiguous assignment of the NMR signals to the atomic sites. Quantum mechanical modelling of the NMR shift parameter indicates a dominant influence of the cations on the isotropic 29Si NMR signal shift. In contrast to this a negligible influence of the geometry of the anions on the NMR signal shift is obtained by these model calculations. The origin of the systematic variation of the isotropic NMR signal shift is not yet clear although an influence of the charge transfer estimated by calculation using the QTAIM approach is indicated.
Advances in Bridging Research and Practice: Introduction to the Second Special Issue on the Interactive System Framework for Dissemination and Implementation

Published: August 2012

AbstractThe need for new ways to bridge the gap between research and practice is clear; the use of evidence‐based prevention programs and implementation with fidelity in practice are strikingly limited. The Interactive Systems Framework for Dissemination and Implementation (ISF) was created to help bridge research and practice by specifying the systems and processes required to support dissemination and implementation of evidence‐based programs, processes, practices, and policies. The ISF identifies three key systems necessary for this process which include the Synthesis and Translation System, the Support System, and the Delivery System. The ISF was featured in a special issue of the American Journal of Community Psychology in 2008. This special issue extends that work by including both researchers who have applied an ISF lens to aspects of their current work and researchers who have proactively applied the ISF in a process that goes across the various systems of the ISF, i.e., Synthesis and Translation, Support, and Delivery. Content areas include: children's mental health, teen pregnancy prevention, HIV prevention, violence prevention, heart disease and stroke prevention, breast cancer prevention, and substance abuse prevention. In this introductory article, we provide a brief description of the history of the ISF and a summary of the articles in the special issue.Special Issue: Advances in Bridging Research and Practice Using the Interactive System Framework for Dissemination and Implementation; Guest Editors: Abraham Wandersman, Paul Flaspohler, Catherine A.

Strand-Biased Gene Distribution in Bacteria Is Related to both Horizontal Gene Transfer and Strand-Biased Nucleotide Composition
Authors: Wu Hao , Qu Hongzhu , Wan Ning , Zhang Zhang , Hu Songnian , Yu Jun 
Published: August 2012

Abstract
Although strand-biased gene distribution (SGD) was described some two decades ago, the underlying molecular mechanisms and their relationship remain elusive. Its facets include, but are not limited to, the degree of biases, the strand-preference of genes, and the influence of background nucleotide composition variations. Using a dataset composed of 364 non-redundant bacterial genomes, we sought to illustrate our current understanding of SGD. First, when we divided the collection of bacterial genomes into non-polC and polC groups according to their possession of DnaE isoforms that correlate closely with taxonomy, the SGD of the polC group stood out more significantly than that of the non-polC group. Second, when examining horizontal gene transfer, coupled with gene functional conservation (essentiality) and expressivity (level of expression), we realized that they all contributed to SGD. Third, we further demonstrated a weaker G-dominance on the leading strand of the non-polC group but strong purine dominance (both G and A) on the leading strand of the polC group. We propose that strand-biased nucleotide composition plays a decisive role for SGD since the polC-bearing genomes are not only AT-rich but also have pronounced purine-rich leading strands, and we believe that a special mutation spectrum that leads to a strong purine asymmetry and a strong strand-biased nucleotide composition coupled with functional selections for genes and their functions are both at work.
THE START OF PERFORMANCE, OR, DOES COLLABORATION MATTER?
Authors: Hooper Michael 
Published: August 2012

AbstractThis article presents a view of the first meetings between the oboe virtuoso Christopher Redgate and the composers Dorothy Ker and Fabrice Fitch. The article details some aspects of these meetings to highlight the processes that are at play in the earliest stages of collaboration. These processes are both practical (in which information about how the oboe works is uncovered and shared) and philosophical (in which the oboe itself becomes a significant source of new possibilities). The article traces a period during which Redgate was developing a new oboe, working with composers to create new repertoire for the new instrument. Arguing for closer attention to the ‘everyday’ aspects of composers and performers working together, the article explores some of the ways in which Redgate pulls apart his experience of performing to develop new technique and to opening up new possibilities for future composition. I also argue that the oboe, as much as the composer and performer, plays a part in shaping musical outcomes.
MEDIUM/FORM RELATIONS IN BRIAN FERNEYHOUGH'S FOURTH STRING QUARTET
Authors: Lippe Klaus 
Published: August 2012

AbstractThe aim of this paper is to re-describe Brian Ferneyhough's compositional practice as an arrangement of medium/form relations in the sense of system theorist Niklas Luhmann. The production process of an artwork is understood as a procedure by which ‘a form is changed for another’, or rather: by which a form becomes a medium for further form distinctions, such that the contingency of the beginning is transformed into the necessity of the final work of art. Based on the preliminary ‘large-scale form’, the fundamental steps in the composition of the first movement of the Fourth String Quartet are observed as recursive operations in a self-referentially closed process of gaining form. Despite its formal closure, the final score's potentiality becomes a medium for further performative and perceptive actualizations. The artwork establishes itself on the level of second order observations, as a difference between the possible and the actual: between medium and form.
HOW DID HOLST CONDUCT ‘THE PLANETS’?
Authors: Gibbs Alan 
Published: August 2012

AbstractAny would-be conductor of The Planets needs first to consult Holst's own recordings of 1923 and 1926; then Imogen Holst's The Music of Gustav Holst (3rd edition, in particular Chapter XXVI), and her and Colin Matthews's contributions to the Collected Facsimile Edition, Volume III. Opinions vary as to how far the constraints of the early recording studio affected the composer's interpretation, so the recent discovery of a miniature score with Sir Henry Wood's annotations on the 1931 Prom performance, where Holst had no such inhibitions, is of unusual interest. Its positive attributes, side by side with Wood's merciless exposing of the difficulties encountered by the composer, are all there. Durations of three movements have been added in Holst's writing, and Wood's own timings shed further light although, sadly, muddied by errors and inconsistencies. But there is new food for thought regarding such aspects as the speed of Saturn and a reminder where the central melody of Jupiter is concerned.
Event-related potentials reveal anomalous morphosyntactic processing in developmental dyslexia
Authors: CANTIANI CHIARA , LORUSSO MARIA LUISA , PEREGO PAOLO , MOLTENI MASSIMO , GUASTI MARIA TERESA 
Published: August 2012

ABSTRACTIn the light of the literature describing oral language difficulties in developmental dyslexia (DD), event-related potentials were used in order to compare morphosyntactic processing in 16 adults with DD (aged 20–28 years) and unimpaired controls. Sentences including subject–verb agreement violations were presented auditorily, with grammaticality and subject number as main factors. Electrophysiological data revealed differences between groups concerning both the latency of the P600 component and the additional presence in the DD group of a negativity broadly diffused all over the scalp. Moreover, these electrophysiological anomalies increased when plural sentences were processed. On the whole, the results support the hypothesis of a linguistic deficit and of different language processing modalities in DD participants.
The impact of instruction on second-language implicit knowledge: Evidence against encapsulation
Authors: TOTH PAUL D. , GUIJARRO-FUENTES PEDRO 
Published: August 2012

ABSTRACTThis paper compares explicit instruction in second-language Spanish with a control treatment on a written picture description task and a timed auditory grammaticality judgment task. Participants came from two intact, third-year US high school classes, with one experiencing a week of communicative lessons on the Spanish cliticse(n= 15) and the other exposed toseonly incidentally (n =20). Explicit instruction consisted of grammar rules with sentence-level examples, followed by communicative tasks. Three test versions were administered within a split-bloc design as a pretest, immediate posttest, and delayed posttest 6 weeks after instruction. The instructed group increased targetlike uses ofseon both tasks and sustained gains through the delayed posttest, although first-language transfer errors persisted. Meanwhile, overgeneralization errors centered on semantic and syntactic contexts similar to the instructional object, aligning with the unergative–unaccusative distinction among intransitive verbs. It is argued that the data provide evidence for the permeability of second-language implicit knowledge to explicit instruction and against total encapsulation as a model of the mind.
The acquisition of passives in Serbian
Authors: PEROVIC ALEXANDRA , VUKSANOVIĆ JASMINA , PETROVIĆ BOBAN , AVRAMOVIĆ-ILIĆ IRENA 
Published: August 2012

ABSTRACTThis study examined the comprehension of actional and psychological verbs in both their active and passive (short and long) forms by 99 Serbian-speaking children. The children, whose age ranged between 3 years, 6 months (3;6) and 7 years, 6 months (7;6), were divided into three groups: 3;6–5 (M = 4.3), 5;1–6;1 (M = 5.6), and 6;2–7;6 (M = 7.0). All groups reached ceiling performance on actives of both actional and psychological verbs. They showed a good performance on passives of actional verbs, both short and long, but an exceptionally low performance on passives of psychological verbs: only the oldest group, 7-year-olds, reached 80% correct performance on psychological passives. There were no differences in the children's performance on short versus long passives of either type of the verb. These results are in line with studies reporting delayed passive comprehension in children younger than 5 in a number of languages, suggesting a delay in the comprehension of this structure cross-linguistically. The discrepancy observed in the comprehension of psychological passives, as opposed to actional actives, fits neatly into Borer and Wexler's account, which relates children's difficulties in this area to their underlying knowledge of argument chains created by movement of sentential elements.
GENDER AND THE POLITICS OF MUSIC IN THE EARLY ISLAMIC COURTS
Authors: Nielson Lisa 
Published: August 2012

Until the ninth century, the role of the professional musician in pre-Islamic Arabia and Mesopotamia was primarily fulfilled by women. Men were socially prohibited from working as musicians, though some transgressed gender and social boundaries by adopting feminine dress and playing ‘women's’ instruments. With the advent of Islam, patronage of qiyān (singing girls), mukhannathūn (effeminates) and later, male musicians, did not substantially change. During the early Abbasid era (750–950 ce), however, their collective visibility in court entertainments was among several factors leading to debates regarding the legal position of music in Islam. The arguments for and against took place in the realm of politics and interpretation of religious law yet the influence of traditional expectations for gendered musical performance that had existed on the cultural landscape for millennia also contributed to the formation of a musical semiotics used by both sides.In this article, I examine the representation of musicians in the early Islamic court in Baghdad from the perspective of select ninth-century Arabic texts. First, I begin with a summary of the gender roles and performance expectations for pre-Islamic court musicians and point to their continuation into the early Islamic courts. Then, I suggest how the figure of the musician became a key referent in the development of a musical semiotics used in medieval Islamic music discourse.
