Collaborative Intelligence - Definition and Measured Impacts on Internetworked e-Work
Authors: Zhong Hao , Levalle Rodrigo Reyes , Moghaddam Mohsen , Nof Shimon Y. 
Published: April 2015

Abstract
Internetworked e-Work is enabling new channels in cyber space for collaboration among physical and cyber agents, e.g., humans, robots, software agents. Research on Collaborative Control Theory (CCT) indicates that building and augmenting the Collaborative Intelligence (CI) of participants in cyber-physical networks can provide better support for achieving their individual and common goals. In spite of its rising significance and popularity, however, no clear and precise definition and universal quantitative measure has been proposed for the CI. In this article, we first formalize the CI by suggesting a formal definition, based on the definitions of its elements - collaboration and intelligence. We then propose a quantitative measure for the CI, adapted from the universal intelligence measure. For illustration, we analyze three recent collaborative e-Work studies at three different scales: (1) Telerobotenabled computer supported collaborative design; (2) Collaborative product line control in supply networks; (3) Demand and capacity sharing in multi-enterprise collaboration. From these case studies, common advantages such as work efficiency, network robustness and stability, service level, resource utilization, and collaboration cost are observed, analyzed, and translated into formal CI measures. Results indicate significant impacts of CI on the efficiency, effectiveness, and quality of collaborative activities in emerging e-Work networks.

Abstract

Background
Radiochemotherapy is the main treatment for patients with squamous cell carcinoma of the anal canal. Anaemia is reported to have adverse effect on survival in cancer patients. The aim of the study was to evaluate the influence of anaemia on radiochemotherapy treatment outcome in patients with squamous cell carcinoma of the anal canal.

Patients and methods
One hundred consecutive patients with histologically confirmed squamous cell carcinoma of the anal canal were treated radically with 3-dimensional conformal or intensity-modulated radiation therapy followed by brachytherapy or external beam radiotherapy boost and with concurrent mitomycin C and 5-fluorouracil. The influence on survival of pre-treatment, mean on-treatment and end-of-treatment haemoglobin (Hb) concentrations was studied.

Results
The 5-year locoregional control, disease free survival, disease specific survival and overall survival rates for all patients were 72%, 71%, 77% and 62%, respectively. In univariate analysis, patients with pre-treatment and end-of-treatment Hb > 120 g/L survived statistically significantly better compared to patients with Hb ≤ 120 g/L. Patients with mean on-treatment Hb > 120 g/L only had statistically significant better locoregional control and overall survival than patients with Hb ≤ 120 g/L. In multivariate analysis, independent prognostic factors were pre-treatment Hb (> 120 g/L vs. ≤ 120 g/L) for overall survival (hazard ratio [HR] = 0.419, 95% confidence interval [CI] = 0.190–0.927, p = 0.032) and stage (I & II vs. III) for disease specific (HR = 3.523, 95% CI = 1.375–9.026, p = 0.009) and overall survival (HR = 2.230, 95% CI = 1.167–4.264, p = 0.015).

Conclusions
The pre-treatment, mean on-treatment and end-of-treatment Hb concentration > 120 g/L carried better prognosis for patients for with squamous cell carcinoma of the anal canal treated with radiochemotherapy. The pre-treatment Hb > 120 g/L was an independent prognostic factor for overall survival of patients with anal canal cancer.
Fine-grained and probabilistic cross-linguistic influence in the pronunciation of cognates: Evidence from corpus-based spontaneous conversation and experimentally elicited data
Authors: Brown Esther L. , Amengual Mark 
Published: April 2015

AbstractThe present study examines variable realizations of Spanish word-initial voiced and voiceless dental stops in Spanish-English cognate pairs. Employing a variationist approach to naturalistic data, we report significantly decreased likelihood of reduced articulations of word-initial /d/ in cognates in spontaneous bilingual Puerto Rican discourse, and no such probabilistic effect for cognates in monolingual Spanish of the same speech community. Using experimentally controlled elicited data of Spanish word-initial /t/, we also find evidence of significant fine-grained effects of English on the articulations of Spanish cognates in the form of lengthened VOT for Spanish-English bilinguals. These results indicate that cross-language lexical connections affect phonetic categories in the speech production of Spanish-English bilinguals. It is proposed that both fine-grained and probabilistic effects of the phonology of one language on another can be explained within the Exemplar Model of Lexical Representation.
Análisis acústico de la vibrante múltiple en el español de Valencia (España)
Authors: García Fernando Melero 
Published: April 2015

Resumen
El objetivo de este estudio es proporcionar un análisis acústico de la producción de la vibrante múltiple en el habla natural de hablantes nativos de Valencia. Para ello, se han analizado 14 entrevistas sociolingüísticas. La vibrante múltiple se analizó en función de diversas variables. Por un lado, se consideraron dos variables dependientes: número de oclusiones y duración de la vibrante múltiple. Por otro lado, las variables independientes son de dos tipos: lingüísticas y extralingüísticas. En general, los resultados revelaron un número considerable de variables no canónicas que contienen menos de dos oclusiones. Con respecto a los factores lingüísticos, se encontraron más producciones canónicas en sílabas tónicas y en posición inicial de palabra. En cuanto a los factores sociales, el grupo de hablantes más jóvenes se caracterizó por producciones más innovadoras no canónicas. Por el contrario, el grupo compuesto por mujeres produjo vibrantes con mayor número de oclusiones y duración que el grupo compuesto por hombres. Finalmente, el nivel de educación de los hablantes pareció no tener un efecto significativo en la producción de la vibrante múltiple.

Published: April 2015

Abstract
Eight species of the family Piophilidae are found in the mainland Ukraine. Five of them, Allopiophila luteata (Haliday, 1833), Parapiophila vulgaris (Fallén, 1820), Protopiophila latipes (Meigen, 1838), Stearibia nigriceps (Meigen, 1826), and Neottiophilum praeustum (Meigen, 1826), are recorded from the first time from Ukraine. Two species, Mycetaulus bipunctatus (Fallén, 1823) and Prochyliza nigrimana (Meigen, 1826), have been previously recorded only from Crimea.
Differences In Skull Size Of Harbour Porpoises, Phocoena phocoena (Cetacea), In The Sea Of Azov And The Black Sea: Evidence For Different Morphotypes And Populations
Authors: Goldin P. E. , Vishnyakova K. A. 
Published: April 2015

Abstract
There are two porpoise stocks in the northern Black Sea: the north-western (Odessa Gulf) and northeastern (Crimean and Caucasian waters); in addition, another stock is in the Sea of Azov. The Azov porpoises are distinct in their body size and biology. This research was conducted on the skulls of stranded sexually mature porpoises from the north-eastern Black Sea, north-western Black Sea and the Sea of Azov. In the north-eastern Black Sea samples, both present-day and old-time, the sexual dimorphism of the skull size was not significant, whereas in the Sea of Azov the females were significantly larger than males. The Azov skulls were strongly different from those from the Black Sea: they were larger, proportionally wider and had the wider rostra; also, there was no significant chronological variation within the Black Sea. The Azov and Black Sea samples were classified with the 100 % success with four variables. The northwestern Black Sea skulls were somewhat intermediate in their characteristics between the Azov and northeastern Black Sea samples, but they were classify ed together with other Black Sea specimens. The difference between the Azov and Black Sea skulls was greater than between many North Atlantic populations, despite the extreme geographical proximity of the two stocks. The low variation within the Black Sea supports the earlier conclusions on the lack of genetic variation: all the Black Sea stocks are expected to be genetically similar sub-populations, whereas the Azov and Marmara stocks possibly represent the genetically distant populations. The porpoises from the Black Sea and the Sea of Azov equally show the traits which characterize the subspecies Phocoena phocoena relicta, but the Black Sea porpoises appear to be more paedomorphic in terms of ontogenetic trajectories.

Th e redefined specimens were previously identify ed as S. aurocinctus (Ohlert, 1865). Specimens of S. aurocinctus were not found in the material. Geographic coordinates of localities and description of S. larae and S. tantulus habitats are provided.
Density Functional Theory Calculations of H/D Isotope Effects on Polymer Electrolyte Membrane Fuel Cell Operations
Authors: Yanase Satoshi , Oi Takao 
Published: April 2015

Abstract
To elucidate hydrogen isotope effects observed between fuel and exhaust hydrogen gases during polymer electrolyte membrane fuel cell operations, H-to-D reduced partition function ratios (RPFRs) for the hydrogen species in the Pt catalyst phase of the anode and the electrolyte membrane phase of the fuel cell were evaluated by density functional theory calculations on model species of the two phases. The evaluation yielded 3.2365 as the value of the equilibrium constant of the hydrogen isotope exchange reaction between the two phases at 39 °C, which was close to the experimentally estimated value of 3.46–3.99 at the same temperature. It was indicated that H+ ions on the Pt catalyst surface of the anode and H species in the electrolyte membrane phase were isotopically in equilibrium with one another during fuel cell operations.
Solving Fractional Partial Differential Equations with Variable Coefficients by the Reconstruction of Variational Iteration Method
Authors: Hesameddini Esmail , Rahimi Azam 
Published: April 2015

Abstract
In this article, we propose a new approach for solving fractional partial differential equations with variable coefficients, which is very effective and can also be applied to other types of differential equations. The main advantage of the method lies in its flexibility for obtaining the approximate solutions of time fractional and space fractional equations. The fractional derivatives are described based on the Caputo sense. Our method contains an iterative formula that can provide rapidly convergent successive approximations of the exact solution if such a closed form solution exists. Several examples are given, and the numerical results are shown to demonstrate the efficiency of the newly proposed method.
3-M syndrome: a novel CUL7 mutation associated with respiratory distress and a good response to GH therapy
Authors: Deeb A , Afandi O , Attia S , Fatih A El 
Published: April 2015

Summary
3-M syndrome is a rare autosomal recessive disorder caused by mutations in the CUL7, OBSL1 and CCDC8 genes. It is characterised by growth failure, dysmorphic features and skeletal abnormalities. Data in the literature show variable efficacy of GH in the treatment of short stature. We report four Emirati siblings with the condition. The index case is a 10-year-old boy with characteristic features, including prenatal and postnatal growth failure, a triangular face, a long philtrum, full lips and prominent heels. Genetic testing confirmed a novel mutation (p.val88Ala) in the CUL7 gene. The parents are healthy, first-degree cousins with nine children, of whom two died in the first year of life with respiratory failure. Both had low birth weight and growth retardation. The boy's older sibling reached an adult height of 117 cm (−6.71 SDS). She was never treated with GH. He was started on GH treatment at 7 years of age, when his height was 94 cm (−5.3 SDS). 3-M syndrome should be considered in children with short stature who have associated dysmorphism and skeletal abnormalities. The diagnosis is more likely to occur in families that have a history of consanguinity and more than one affected sibling. Death in early infancy due to respiratory failure is another clue to the diagnosis, which might have a variable phenotype within a family. Genetic testing is important for confirming the diagnosis and for genetic counselling. GH treatment might be beneficial in improving stature in affected children.

Learning points

3-M syndrome should be considered in families that have more than one sibling with short stature, particularly if there is consanguinity.

Syndrome phenotype might be variable within a family with the same mutation.

Genetic analysis is helpful in confirming diagnosis in the presence of variable siblings' phenotype.

GH treatment might be useful in improving stature in 3-M syndrome.

ABSTRACTPhotovoltaic (PV) systems are progressively used for decentralized electricity generation. To obtain the maximum yield from such systems, optimisation of all components is essential. In this contribution, we provide a comprehensive modelling and sizing of PV systems for any location. Three applications are here presented providing real time monitoring of PV potential, accurate prediction of yield taking into account thermodynamic temperature effects, optimization of modules orientation addressing the effects of shading and efficient sizing of inverter for a higher yield output. When combined, these models can accurately predict the real time performance of any PV system.

ABSTRACTFor the industrial application of silicon thin film solar cells, the current focus is on how to realize high-efficiency low-cost production process and minimize light-induced degradation effect, thus effectively reducing the balance-of-system (BOS) costs of system integration. In this paper, a brief introduction based on our development and application in this area is presented, highlighting in the achievement of some layers in a-Si:H/μc-Si:H tandem solar cell by optimizing the property of single layers, such as amorphous intrinsic layer, intermediate reflective layer and microcrystalline intrinsic layer. After transferring the process achievement to the industrial production line, we obtained the low-cost thin-film silicon solar cells with high photovoltaic conversion efficiency of 10.2%.
História, memória e ficção: que fronteiras?
Authors: Matos Sérgio Campos 
Published: April 2015

Sociólogos e historiadores do século XX estabeleceram uma clara distinção entre história e memória. Mas nos últimos decênios tem-se chamado a atenção para aquilo que pode haver de comum entre esses dois campos que nem sempre coincidem. Pretende-se problematizar as complexas relações entre história e memória: as exigências críticas da escrita da história e os registos das diferentes memórias (memória individual, memórias coletivas), equacionando também a relação memória/esquecimento. E o que distingue a história da ficção? Em que medida podem as memórias ser permeáveis à imaginação? Todos ficcionalizamos o nosso passado. Poder-se-á reduzir a escrita da história a uma dimensão narrativa?
Fontes literárias da cultura brasileira para a história dos saberes psicológicos
Authors: Massimi Marina 
Published: April 2015

Neste artigo é discutida a utilização das fontes literárias no âmbito da história dos saberes psicológicos. Em primeiro lugar, apresenta-se a contribuição de Dilthey e de Huizinga na discussão das interfaces entre história, psicologia e literatura. Em segundo lugar, apresenta-se um exemplo de análise de fonte literária no âmbito da história dos saberes psicológicos: o estudo da novela alegórica do jesuíta Alexandre de Gusmão, História do Predestinado Peregrino e de seu irmão Precito (1682). Aponta-se que a fonte literária pode ser enfocada da perspectiva da história dos saberes psicológicos, seja por ser transmissora de conceitos e práticas psicológicos, seja pela ação exercida no dinamismo psíquico dos destinatários por meio de sua construção retórica.
Living in a same microhabitat should means eating the same food? Diet and trophic niche of sympatric leaf-litter frogs Ischnocnema henselii and Adenomera marmorata in a forest of Southern Brazil

Published: April 2015

In this study we analyzed diet composition, niche breadth and overlap of the two leaf-litter frogs Ischnocnema henselii and Adenomera marmorata. Frogs were collected in an Atlantic Rainforest area in the Reserva Natural Salto Morato, in Paraná State, Southern Brazil, using plots of 16 m2 established on forest floor. Ischnocnema henselii consumed 18 different types of prey and the diet of this species was composed predominantly by Hymenoptera (Formicidae) (15.4%), Araneae (13.83%), Orthoptera (6.15%) and Opiliones (6.15%), whereas Adenomera marmorata consumed 15 different types of prey and its diet was composed mainly by Hymenoptera (Formicidae) (45.7%), Acari (31.8%) and Blattodea (14.8%). The niche breadth of I. henselii was BA = 0.43 and that of A. marmorata was BA = 0.19. The diet of the two sympatric species of leaf-litter frogs was basically composed by arthropods and the trophic niche overlap among them did not differ from expected at random. The differences in prey consumption should potentially facilitate the coexistence of two sympatric frogs on the forest floor. Possibly, this difference of prey consumption partly reflects differences in jaw width, species-specific body size of the two species and the period of activity of these two species.

ABSTRACT

Objective:
To examine the expression of possible secular trend in timing of the emergence of permanent teeth in Finnish children over the past few decades, considering the differences between genders.

Materials and Methods:
Two age groups of Finnish children, one born in 1976–1985 (group 1980) and the other born in 1999–2002 (group 2000), were examined. Group 2000 comprised 483 children (235 girls and 248 boys) aged 6.4 to 8.5 years at the time of the examination, and the same children were examined at the age of 9.0 to 11.8 years. Altogether 405 children could be recalled, 196 girls and 209 boys. For comparison, matching age groups were selected from the group 1980 data (n = 1579), resulting in a sample of 312 children (155 girls and 157 boys) aged 6.4 to 8.5 years and 393 children aged 9.0 to 11.8 years. The emergence stage of each permanent tooth was determined clinically (Grades 0–3), based on which the subjects were furthermore divided according to the emergence stage of the dentition.

Results:
Linear regression models showed that the permanent teeth of the first phase of the mixed dentition erupted earlier in group 2000 than in group1980, but the teeth of the second phase of the mixed dentition erupted later in group 2000. Girls showed more advanced tooth eruption than boys.

Conclusion:
The longer duration of mixed dentition in group 2000 than in group 1980 makes the duration of combined follow-up and active treatment longer, and should be considered in timing of efficient orthodontic treatment.
Vascular Access for Hemodialysis: When and how?

Published: April 2015

Abstract
As chronic kidney disease (CKD) progresses to the terminal stage, proper actions must be taken to prepare the patient for the initiation of the renal replacement therapy (RRT). If hemodialysis is an option for RRT, decisions should be made about the right vascular access for each individual patient. The available options for vascular access include the use of native arteriovenous fistulas (AVF), synthetic arteriovenous grafts (AVG) and double lumen dialysis catheters. With the help of ultrasound mapping, chances for choosing a right access are today very high. For hemodialysis patients the selection of the proper vascular access is of vital issue in regard of preventing complications and unnecessary procedures. Planning, creation and monitoring of the vascular access in dialysis patients should involve not only the nephrologist, but also the vascular surgeon and the interventional radiologist. Thus, multidisciplinary approach should be taken, in order to choose the way that has the most advantages and the least damage for the patient. That is the proper mode for hemodialysis patients to have longer and better quality of life.
