Genus 0 characteristic numbers of the tropical projective plane
Authors: Bertrand Benoît , Brugallé Erwan , Mikhalkin Grigory 
Published: November 2013

AbstractFinding the so-called characteristic numbers of the complex projective plane$ \mathbb{C} {P}^{2} $is a classical problem of enumerative geometry posed by Zeuthen more than a century ago. For a given$d$and$g$one has to find the number of degree$d$genus$g$curves that pass through a certain generic configuration of points and at the same time are tangent to a certain generic configuration of lines. The total number of points and lines in these two configurations is$3d- 1+ g$so that the answer is a finite integer number. In this paper we translate this classical problem to the corresponding enumerative problem of tropical geometry in the case when$g= 0$. Namely, we show that the tropical problem is well posed and establish a special case of the correspondence theorem that ensures that the corresponding tropical and classical numbers coincide. Then we use the floor diagram calculus to reduce the problem to pure combinatorics. As a consequence, we express genus 0 characteristic numbers of$ \mathbb{C} {P}^{2} $in terms of open Hurwitz numbers.
Audiovisual Speech Integration Does Not Rely on the Motor System: Evidence from Articulatory Suppression, the McGurk Effect, and fMRI
Authors: Matchin William , Groulx Kier , Hickok Gregory 
Published: November 2013

Abstract
Visual speech influences the perception of heard speech. A classic example of this is the McGurk effect, whereby an auditory /pa/ overlaid onto a visual /ka/ induces the fusion percept of /ta/. Recent behavioral and neuroimaging research has highlighted the importance of both articulatory representations and motor speech regions of the brain, particularly Broca's area, in audiovisual (AV) speech integration. Alternatively, AV speech integration may be accomplished by the sensory system through multisensory integration in the posterior STS. We assessed the claims regarding the involvement of the motor system in AV integration in two experiments: (i) examining the effect of articulatory suppression on the McGurk effect and (ii) determining if motor speech regions show an AV integration profile. The hypothesis regarding experiment (i) is that if the motor system plays a role in McGurk fusion, distracting the motor system through articulatory suppression should result in a reduction of McGurk fusion. The results of experiment (i) showed that articulatory suppression results in no such reduction, suggesting that the motor system is not responsible for the McGurk effect. The hypothesis of experiment (ii) was that if the brain activation to AV speech in motor regions (such as Broca's area) reflects AV integration, the profile of activity should reflect AV integration: AV &gt; AO (auditory only) and AV &gt; VO (visual only). The results of experiment (ii) demonstrate that motor speech regions do not show this integration profile, whereas the posterior STS does. Instead, activity in motor regions is task dependent. The combined results suggest that AV speech integration does not rely on the motor system.
Acoustic Noise Improves Visual Perception and Modulates Occipital Oscillatory States
Authors: Gleiss Stephanie , Kayser Christoph 
Published: November 2013

Abstract
Perception is a multisensory process, and previous work has shown that multisensory interactions occur not only for object-related stimuli but also for simplistic and apparently unrelated inputs to the different senses. We here compare the facilitation of visual perception induced by transient (target-synchronized) sounds to the facilitation provided by continuous background noise like sounds. Specifically, we show that continuous acoustic noise improves visual contrast detection by systematically shifting psychometric curves in an amplitude-dependent manner. This multisensory benefit was found to be both qualitatively and quantitatively similar to that induced by a transient and target synchronized sound in the same paradigm. Studying the underlying neural mechanisms using electric neuroimaging (EEG), we found that acoustic noise alters occipital alpha (8–12 Hz) power and decreases beta-band (14–20 Hz) coupling of occipital and temporal sites. Task-irrelevant and continuous sounds thereby have an amplitude-dependent effect on cortical mechanisms implicated in shaping visual cortical excitability. The same oscillatory mechanisms also mediate visual facilitation by transient sounds, and our results suggest that task-related sounds and task-irrelevant background noises could induce perceptually and mechanistically similar enhancement of visual perception. Given the omnipresence of sounds and noises in our environment, such multisensory interactions may affect perception in many everyday scenarios.
Les lead-users en marketing : Interrogations et nouvelles contributions psychométriques

Published: November 2013

Résumé Les lead-users jouent un rôle significatif dans le développement de nouveaux produits. Leur identification constitue un enjeu important pour les entreprises qui souhaitent innover. Bien qu’une dizaine de mesures d’auto-évaluation du lead-user soit disponible, aucune n’est pleinement satisfaisante. Une nouvelle mesure est donc construite, validée et normée sur plusieurs catégories de produits, grâce à trois séries d’études. La première élabore une version épurée de l’échelle. La seconde établit la validité de construction (convergente et discriminante) et normalise l’échelle sur un échantillon représentatif de la population française (n = 2000) pour trois catégories de produits alimentaires ; nous confirmons que le lead-user et le leader d’opinion sont deux concepts différents, mais qu’un petit nombre d’individus peut cumuler ces deux statuts ; le caractère lead-user est également contingent à la catégorie de produit. La troisième confirme la validité nomologique de l’échelle pour un nouvel échantillon représentatif (n = 456) et une nouvelle catégorie de produit : le lead-usership est relié positivement aux compétences pour la co-création et à l’engagement dans la co-création de jeux vidéo.
Discrepancies in Parent and Teacher Ratings of Social-Behavioral Functioning of Children With Chromosome 22q11.2 Deletion Syndrome: Implications for Assessment
Authors: Shashi Vandana , Wray Emily , Schoch Kelly , Curtiss Kathleen , Hooper Stephen R. 
Published: November 2013

Abstract
Children with 22q11.2 deletion syndrome exhibit high rates of social-behavioral problems, particularly in the internalizing domain, indicating an area in need of intervention. The current investigation was designed to obtain information regarding parent and teacher ratings of the social-emotional behavior of children with 22q11DS. Using the Child Behavior Checklist (CBCL), the sample included 67 children with 22q11DS and 59 control subjects. Results indicated significant differences in social-behavioral functioning of children with 22q11DS, as compared to a control group, based on rater type. Specifically, parents reported more difficulties with internalizing problems, withdrawal, and social problems in children with 22q11DS. In contrast, teachers perceived few differences between children with 22q11DS and unaffected children. Correlational analyses indicated weak concordance between parent and teacher reports, with no significant correlations on any of three summary scales. The findings support the use of multiple methods of assessment and multiple informants when collecting information regarding the social-behavioral functioning of children with 22q11DS, and that interpretations based on only one informant/setting need to be made cautiously.
Perceptual Factors Influence Visual Search for Meaningful Symbols in Individuals With Intellectual Disabilities and Down Syndrome or Autism Spectrum Disorders
Authors: Wilkinson Krista M. , McIlvane William J. 
Published: November 2013

Abstract
Augmentative and alternative communication (AAC) systems often supplement oral communication for individuals with intellectual and communication disabilities. Research with preschoolers without disabilities has demonstrated that two visual–perceptual factors influence speed and/or accuracy of finding a target: the internal color and spatial organization of symbols. Twelve participants with Down syndrome and 12 with autism spectrum disorders (ASDs) completed two search tasks. In one, the symbols were clustered by internal color; in the other, the identical symbols had no arrangement cue. Visual search was superior in participants with ASDs compared to those with Down syndrome. In both groups, responses were significantly faster when the symbols were clustered by internal color. Construction of aided AAC displays may benefit from attention to their physical and perceptual features.
Cationization of Eucalyptus grandis 4-O-methyl glucuronoxylan for application as a wet-end additive in a papermaking process
Authors: Postma Dirk , Chimphango Annie F.A. , Görgens Johann F. 
Published: November 2013

Abstract
Hemicelluloses extracted prior to kraft pulping can subsequently be introduced as wet-end strength additives in a papermaking process. The 4-O-methyl glucuronoxylan (Me-GluX) extracted from Eucalyptus grandis (E. grandis) under mild alkaline conditions was cationized and added to bleached kraft pulp (BKP) from E. grandis before refining. The cationization by 2,3-epoxypropyltrimethylammonium chloride (ETA) was done in a central composite designed experiment. Me-GluX with an average molecular weight of 52,000 g mol-1 contained 27% Klason residue. The cationic Me-GluX had degrees of substitution of the cationic side chain between 0.05 and 0.73 and uronic acid content between 6.1% and 12.7%. The cationic Me-GluX as a wet-end strength additive was compared to cationic starch (CatStarch 134) in handsheets. The handsheets with cationic Me-GluX showed improvement in tensile, burst, and tear indices and had lower air permeability than those with CatStarch 134 at dosages between 1.0% and 2.0%. Accordingly, cationized Me-GluX is a potential green wet-end strength additive, which could fully or partially replace the synthetic and starch additives.
Human septin isoforms and the GDP-GTP cycle
Authors: Zent Eldar , Wittinghofer Alfred 
Published: November 2013

Abstract
Septins form oligomeric complexes consisting of septins from different subgroups, which form filaments that are involved in a number of biological processes. They are GTP-binding proteins that contain all the necessary elements to perform the general GDP-to-GTP conformational switch. It is however unclear whether or not such a switch is important for the dynamics of septin filaments. Here we investigate the complex GTPase reaction of members of each of the four human septin groups, which is dominated by the stability of dimer formation via the nucleotide binding or so-called G-interface. The results also show that the actual hydrolysis reaction is very similar for three septin groups in the monomeric state while the Sept6 has no GTPase activity. Sept7, the only member of the Sept7 subgroup, forms a very tight G-interface dimer in the GDP-bound state. Here we show that the stability of the interface is dramatically decreased by exchanging GDP with a nucleoside triphosphate, which is believed to influence filament formation and dynamics via Sept7.
Numerical Structural Analysis of NPP Reinforced Concrete Structures Under Seismic Loading / Numeryczna Analiza Strukturalna Żelbetowych Konstrukcji Elektrowni Jądrowych W Warunkach Obciążeń Sejsmicznych
Authors: Aleshin Vladimir , Seleznev Vadim 
Published: November 2013

Abstract
The paper describes an approach to the numerical analysis of response of nuclear power plant buildings including soil-structure interaction effects. A reinforced concrete structure of an NPP reactor building under operating and seismic loadings is considered. The simulated seismic load corresponds to a maximum designed earthquake of magnitude 7 (the peak ground surface acceleration is 0.12 g). The numerical analysis was performed by the finite element method in a 3D nonlinear statement using the FEM-programs ANSYS and LS-DYNA. Review of the numerical analysis results demonstrated that the presented technique can be successfully applied to seismic design of NPP structures.
Possibility of Application of the Theory of Semi-Markov Processes to Determine Reliability of Diagnosing Systems / MOŻLIWOŚĆ ZASTOSOWANIA TEORII PROCESÓW SEMI-MARKOWA DO OKREŚLENIA NIEZAWODNOŚCI SYSTEMÓW DIAGNOZUJĄCYCH
Authors: Girtler Jerzy 
Published: November 2013

Abstract
The paper provides justification for the necessity to define reliability of diagnosing systems (SDG) in order to develop a diagnosis on state of any technical mechanism being a diagnosed system (SDN). It has been shown that the knowledge of SDG reliability enables defining diagnosis reliability. It has been assumed that the diagnosis reliability can be defined as a diagnosis property which specifies the degree of recognizing by a diagnosing system (SDG) the actual state of the diagnosed system (SDN) which may be any mechanism, and the conditional probability p(S*/K*) of occurrence (existence) of state S* of the mechanism (SDN) as a diagnosis measure provided that at a specified reliability of SDG, the vector K* of values of diagnostic parameters implied by the state, is observed. The probability that SDG is in the state of ability during diagnostic tests and the following diagnostic inferences leading to development of a diagnosis about the SDN state, has been accepted as a measure of SDG reliability. The theory of semi-Markov processes has been used for defining the SDG reliability, that enabled to develop a SDG reliability model in the form of a seven-state (continuous-time discrete-state) semi-Markov process of changes of SDG states.

Abstract
This paper presents an application of the FMEA (Failure mode and effects analysis) to evaluate the operational risk in railway transport. The methodology developed by the Department of Rail Transport (KTS), including approval thresholds for risk adopted, the model forms (hazard record, FMEA form) were adopted in the Polish railways as a standard to evaluate the operational risk for operators and infrastructure managers. Reacting to the development of requirements for security management - Regulation EC No 445 of 2011 - Department of Rail Transport proposed the standard RAMS - PN - EN 50126 to oversee rail vehicles. This solution is currently being implemented in several entities building maintenance management systems (MMS) for the wagons. This article is dedicated to the people who deal with issues of safety management both in the transport of goods and people as well as the maintenance of rail vehicles.
Ecological Security of a Marine Combustion Engine – A Formal Approach / Bezpieczeństwo Ekologiczne Silnika Okrętowego – Podejście Formalne
Authors: Merkisz Jerzy , Piaseczny Leszek 
Published: November 2013

Abstract
The authors have formed a definition of „ecological security of a marine combustion engine” originating from a general notion of ‘security’. The process of changes of the engine condition influencing the ecological security has been described formally. Based on this process the authors have introduced the notion of structural function of an engine and the structure of its ecological security. The state of ecological security of an engine as a whole has been formulated as a stochastic process and the function, being a one-dimensional distribution of this process, has been used as a measure of the ecological security of an engine at any given moment in its service life. A general example of optimization of this structure has been given based on the fulfillment by the engine of the requirements related to the emission of nitric oxides. It has been assumed that the actions taken aiming at the fulfillment of these requirements allow an obtainment of certain structures of the engine ecological security.

Published: November 2013

Abstract
In this work, algorithms have been used to compare the methods for determining reliability of critical points. Generalized models Stress-Strength- Interference (SSI) and Stress-Strength-Time (SST) have been analyzed. Input to the algorithms, stress and strength were generated by using the Markov chain model based on actual flight records. With this approach methods of determining the reliability of critical points of a helicopter’s structure are justified.
Impact of Infrastructure Type on Reliability of Railway Transportation System / Wpływ Rodzaju Infrastruktury Na Niezawodność Systemu Transportu Szynowego
Authors: Restel Franciszek J. 
Published: November 2013

Abstract
In this paper, the author’s research work is focused on infrastructure impact on railway transportation system reliability. The aim of research described in the paper is to determine correlation between type (and age) of used infrastructure elements, and number of occurring failures. For this purpose, subsystem of infrastructure and associated with it events, were divided into main groups. Examples of groups are: track, train operation devices (related to operating control points or railway line), level crossings, etc. The second aspect is correlation between type of infrastructure and failure consequences. It is required from transportation that it is possible to achieve the right place at the right time in a safety way. Therefore, from the point of view of transportation process, which is the main goal of transportation system, the most significant failure consequences are delays. Moreover, speaking about reliability and safety of railway transportation system, the question arises what is the relation between number of trains and number of unwanted events?

Published: November 2013

Abstract
CWSS exploitation in terms of belonging to a critical infrastructure is an important issue and requires a detailed analysis. Therefore it is important to develop emergency plans for the supply of drinking water for different crisis situations, as well as detailed analysis of the risk of possible undesirable events in CWSS, in order to develop a comprehensive safety management program of the system. In this work the problems associated with the operation of CWSS in terms of belonging to critical infrastructure were presented. Also the methodology to determine the crisis management time in the WSS, connected with a shortage of drinking water was shown.
ISOLATION, IDENTIFICATION AND ANTIBIOTIC RESISTANCE OF AEROMONAS SPP. AND SALMONELLA SPP. FROM THE FRESH WATER LOACH, LEPIDOCEPHALICHTHYS GUNTEA AND WATER OF TERAI RIVER LOTCHKA, WEST BENGAL, INDIA
Authors: Roy Rudra Prasad , Bahadur Min , Barat Sudip 
Published: November 2013

Abstract
An investigation was conducted to identify the bacterial isolates and to study the antibiotic resistance patterns of Aeromonas spp. and Salmonella spp. from the skin, gills, and gut of the fresh water loach, Lepidocephalichthys guntea (HAMILTON BUCHANAN) and water sampled from four different sites along the River Lotchka in Darjeeling District, West Bengal, India. Isolated bacteria were identified by different biochemical procedures, and Polymerase Chain Reaction was performed using genus specific 16S rDNA primers for confirmation of identification of Aeromonas spp. and Salmonella spp. Antibiotic susceptibility test of bacterial isolates was also done by Disc Diffusion method. A total of 49 Aeromonas spp. and 24 Salmonella spp. were isolated from tested samples. Maximum resistance was exhibited for Penicillin-G, Ampicillin, and Cephalothin (>75% resistant Aeromonas spp. and >60% Salmonella spp. in the four different sites of river and body parts of fish). Ciprofloxacin and Tetracycline resistance was almost nil. The results indicated that the river water and resident fish were contaminated with multi-antibiotic resistant enteric pathogenic bacteria. This study, thus, provides valuable information for making policy decisions aimed at reducing microbial contamination of fish and the indiscriminate use of antibiotics.
Changing Criticism of Swahili Qur'an Translations: The Three ‘Rods of Moses’
Authors: van de Bruinhorst Gerard C. 
Published: November 2013

This article examines three Swahili books with the same title Fimbo ya Musa (‘The Rod of Moses’), published between 1970 and 2010, each of which critically investigates Qur'an translations and vernacular religious texts in Swahili. The first Fimbo was written by the Kenyan Ahmad Ahmad Badawy and criticises one of the earliest Swahili Qur'an translations, by Abdullah Saleh al-Farsy. In the second, Nurudin Hussein Shadhuly, head of the Shadhuly/Yashrutiyya Ṣūfī branch in Tanzania examines and condemns the translation efforts by Saidi Musa, a student of al-Farsy. The final Fimbo is a treatise by the Ibāḍī scholar Juma al-Mazrui from Oman and digitally distributed in 2010 which deals with the doctrine of God's visibility in the hereafter and is an answer to the Salafiyya Tanzanian Kassim Mafuta's 2008 work on this topic. The example of these three polemics over the last four decades shows the shifting concerns in the reaction to the translated Qur'an in Swahili. The act of translation from Arabic to the vernacular is no longer attacked, but rather the theological implications of a deficient translation are at the heart of the more recent discussions. While authoritative knowledge is still associated with a high command of Arabic, affiliation to a particular school of law or intellectual genealogy is not. Religious learning is no longer primarily transmitted through well-established links of personal authorities, but can increasingly be derived from private study and reading. As a direct result of this opening up of a wide field of knowledge for a non-Arabic reading audience, the potential numbers of discussants increases: each new Swahili Qur'an translation reveals more of the enigmatic character of the Qur'an and fuels new debates.
