Brokerless inter-domain virtual network embedding: A blockchain-based approach
Authors: Rizk Amr , Bisbal Jordi , Bergsträßer Sonja , Steinmetz Ralf 
Published: November 2018

Abstract
The blockchain technology enables entities to query and alter information without trusting a middle party while providing a secure data storage in a decentralized manner. In this paper, we focus on an IT data supply chain scenario, where multiple actors negotiate a tenancy agreement for virtualized network resources. This process consists of service providers (SPs) requesting the embedding of specified virtual networks across multiple infrastructure providers (InPs). Since InPs are typically not willing to disclose detailed internal network information, this is a major deal breaker that hampers the efficiency of the service negotiation process. After reviewing the related work on centralized and decentralized virtual network embedding (VNE) approaches, we briefly discuss the reasons for a blockchain approach for this problem. Our approach comprises of a brokerless blockchain based system, that uses smart contracts and a VN partitioning algorithm based on the Vickrey auction model. Finally, we investigate the feasibility of our approach, by first analyzing the behavior of the introduced auction model in adverse conditions and by secondly evaluating the blockchain performance given different consensus protocols.

1-O2PPh2)2(η
1-HOCH3)2(μ-bpe)2·CH3OH]
n
(1) and [Mn2(μ-O2PPh2)4(μ-bpe)2]
n
(2), were assembled in single-pot reactions from [Mn(CH3COO)2·4H2O], Ph2P(O)OK and trans-1,4-bis(4-pyridyl)ethene (bpe). The products were characterized by single-crystal X-ray diffraction, which revealed a one-dimensional metal-organic ladder type in 1 and a two-dimensional rectangular grid type in 2. Both 1 and 2 are constructed from six-coordinate Mn(II) nodes that adopt distorted octahedral (MnN4O2) environments; the adjacent nodes are connected by the μ-bpe linkers in 1 or μ-bpe and μ-O2PPh2 linkers in 2 to form different metal-organic networks. The catalytic property of complex 1 for selective thioether oxidation was also investigated in this work.

Published: November 2018

A educação a distância, associada ao uso das tecnologias da informação e da comunicação, é uma forma viável de promover a extensão universitária. Tal ação colabora para desenvolver novas formas de ensinar, de aplicar estratégias de ensino e gera dados para compreensão de tais questões, contemplando, assim, os três grandes objetivos da universidade: docência, pesquisa e extensão. O presente trabalho, de natureza descritiva, visa apresentar a produção de um projeto de extensão universitária como possibilidade de aproximação entre universidade e sociedade a partir do processo de criação de cursos de difusão científica de temas de um Programa de Pós-Graduação em Psicobiologia. O processo envolveu a escolha das áreas e conteúdos dos cursos, do público-alvo, ambiente virtual de aprendizagem e das formas de divulgação. Foram estruturados quatro cursos, sendo que um deles foi realizado e contou com a participação de 81 alunos. Concluímos que o processo de criação da proposta fomentou habilidades docentes da equipe e que os cursos se configuram como potenciais formas de extensão universitária e divulgação científica. A obtenção de dados dos participantes dos cursos poderá embasar estudos futuros.

Nocturnidad y Noctis: Consideraciones para la etnografía de trabajo de producción de nocturnidad
Authors: Becerra Pozos Julio César 
Published: November 2018

Abstract Partiendo de la reflexión teórica que procura hacer una distinción de la noche como algo más que un ciclo natural, considerándola una configuración socio espacial y temporal, cargada por la subjetividad de todos los que participan en ella, así como de estructuras culturales y relacionales; articulándola desde lo laboral, se propone analizarla desde dos facciones sumamente interconectadas: noctis y nocturnidad.Centrando la propuesta de este artículo en la nocturnidad; mediante el estudio etnográfico de las características siu generis del trabajo de producción de interacciones realizado por meseros y meseras en espacios semi privados de venta y consumo de alcohol en dos subconjuntos de bares de la Ciudad de México, se conceptualiza a dicha actividad como un trabajo no clásico de producción de nocturnidad.Más adelante, se presentan las consideraciones y adaptaciones a las técnicas y estrategias de investigación utilizadas, además de los desafíos éticos y prácticos que se generan en las etnografías de trabajo de nocturnidad. Finalmente, se hace hincapié en la necesidad de una conceptualización configuracional y ad hoc para el estudio etnográfico de las multiplicidades del trabajo de economía nocturna en el servicio de producción de interacciones.Palabras clave: Nocturnidad; Trabajo no clásico; Performance laboral; Economía de tiempo nocturno; Etnografía AbstractStarting on a theoretical reflection, in which the night is a social, spacial temporal configuration, full of the subjectivity of the cultural and relational structures of those who participate on it, rather than just a natural cycle; once joint with the labor perspective, it’s the proposal of this article to analyze the night from it’s two highly related components: noctis and nocturnidad.The considerations and adaptations to the research technics and strategies used, along with the ethical and practical challenges from the ethnography of the nocturnity work, comes next. Finally, the emphasis on the need of an ad hoc configurational conceptualization in the ethnographic study of night time economy work diversity.Key words: ethnography, nocturnity, night labour, non classic work, night time economy
Discriminación, degradación y biologicismo: el tratamiento dado a los últimos peldaños de la clase trabajadora en Córdoba, Argentina
Authors: Zeballos Juan Manuel 
Published: November 2018

No es novedad que en una sociedad capitalista como la argentina, a la igualdad ciudadana se le opone la desigualdad de clase. A la igualdad formal ante la Ley, se le enfrenta la desigualdad material manifiesta en las diferencias en la calidad de vida. Sin embargo, no resulta frecuente detenerse en las implicancias de orden valorativo que las clases sociales conllevan.Este artículo se propone determinar la estima social y las prácticas de discriminación imperantes sobre los peldaños más deprimidos de la clase trabajadora en Córdoba, Argentina. Atender a tal propósito demandó adentrarse en los espacios en que este sector de la clase obrera vive -o mal vive-, las villas.[1] Es decir, desarrollar una labor etnográfica.Luego del trabajo de campo se puede concluir que a la parcialidad más empobrecida de la clase asalariada no sólo se la discrimina sistemáticamente, sino que también se le ha adjuntado una estima inferiorizante, degradante y estigmatizante. Al tiempo que esa estima tiene la funcionalidad de legitimar ante el resto de la sociedad las condiciones de vida a las que está sometido dicho sector de la clase trabajadora.En este trabajo se adelanta parte de los resultados obtenidos en una investigación de doctorado, la cual tiene por temáticas la existencia degradada y el diacrítico-estigma biologicista en la ciudad de Córdoba.[1] La villa, también llamada “villa miseria” y “villa de emergencia”, es el conjunto de casas o casillas precarias o sumamente precarias, donde se aloja el sector más bajo del proletariado. Si bien existe cierta variedad en las condiciones de habitabilidad, por lo general no las reúnen o apenas las alcanzan. La villa es el equivalente argentino a la favela brasileña.
NOVO COSMOPOLITISMO, COMUNIDADES E OCUPAÇÕES: PROPOSTAS PARA VIVER UMA ARQUITETURA DO POR VIR (À VENIR)
Authors: Paese Celma 
Published: November 2018

O novo cosmopolitismo proposto por Derrida anuncia-se como uma promessa de uma hospitalidade mais justa, aquela que tenta fazer o impossível: se expor sem limites ao que chega começando por acolher sem cálculo e sem reservas o outro singular e não só o cidadão. Neste brevíssimo ensaio procuramos refletir sobre a cidade que vai além da espetacular – considerada por muitos como legítima representante da urbe contemporânea – e os processos sociais que desafiam os limites e paradigmas espaciais existentes, promovendo a desestabilização da ‘zona de conforto espacial’ ao trazerem à luz as populações ignoradas – embora circunscritas nos processos urbanos – e suas potências econômicas, culturais e sociais. Desta maneira, convido aos arquitetos para enxergar além das convencionais fronteiras de percepção das relações entre o Humano e a Arquitetura das Cidades impostas pelo capital.Palavras-chave: derrida e arquitetura, contramapas, cartografia da hospitalidade,urbanismo contemporâneo, projeto de arquitetura e urbanismo.
Management of precocious puberty in girls with McCune–Albright syndrome using letrozole
Authors: Wang Xi , Yu Qi 
Published: November 2018

Objective
To evaluate the safety and efficacy of letrozole in girls with progressive precocious puberty (PP) associated with McCune–Albright syndrome (MAS).

Design
Monocentric retrospective cross-sectional and longitudinal study of consecutive patients.

Patients
Ten MAS patients treated at Peking Union Medical College Hospital between September 1999 and December 2017 were retrospectively reviewed; those with complications due to PP were followed.

Results
The mean age at letrozole initiation was 4.5 ± 2.6 years, while the mean duration of treatment was 3.3 ± 2.4 years. Letrozole was highly effective at decreasing the rate of skeletal maturation, with a significant decrease in the bone age-to-chronological age (BA/CA) ratio from 1.9 ± 1.1 pre-treatment to 1.5 ± 1.2 on letrozole treatment (P = 0.016). Moreover, growth velocity Z-scores declined from 0.41 ± 0.5 to −0.2 ± 0.31 with treatment (P < 0.001). Predicted adult height Z-scores increased significantly from −2.03 ± 2.33 at baseline to 1.13 ± 0.84 following treatment initiation (P = 0.029). Moreover, vaginal bleeding declined significantly on letrozole.

Conclusions
Our findings suggest that letrozole may be an effective therapy in some girls with MAS, as treatment results in improved BA/CA ratio, growth velocity and predicted adult height. Possible adverse effects include nettle rash.
Plasmid copy number and qnr gene expression in selection of fluoroquinolone-resistant Escherichia coli
Authors: Gulyás Dániel , Kocsis Béla , Szabó Dóra 
Published: November 2018

Fluoroquinolone resistance in Enterobacteriales is developed by chromosomal and plasmid-mediated mechanisms. Plasmids play an important role in dissemination of resistant genes and they carry genes that protect bacteria in different stress-induced situations. In this study, we studied Escherichia coli strains, each carried one plasmid-mediated quinolone resistance determinant namely, qnrA1, qnrB1, qnrC1, and qnrD1. We exposed 0.5 McFarland density of each strain to 0.5 mg/L ciprofloxacin from the period of 30, 60, 90, and 120 min over 24 h. All treated strains were further exposed to a constantly increasing 1, 2, 4, and 8 mg/L ciprofloxacin solution through 24, 48, and 120 h. In given timepoints, RNA was extracted from all treated strains. Expression of qnrA1, qnrB1, qnrC1, and qnrD1 was investigated by quantitative PCR. Mutations in gyrA and parC genes were analyzed by PCR and nucleic acid sequencing. In this study, during 0.5 mg/L ciprofloxacin exposition, the following expression levels were detected: 1.2 for qnrA1, 1.47 for qnrD1, 12.44 for qnrC1, and 80.63 for qnrB1. In case of long-term study, we selected a resistant strain in qnrB1-positive E. coli, and its expression increased from 105.91 to 212.31. On the contrary, plasmid copy number increased in time from 1 to 4.13. No mutations in gyrA or in parC chromosomal genes of treated strains were detected. Our results show that qnrB1-positive E. coli strain was able to develop fluoroquinolone resistance by upregulated qnrB1 expression that was linked to a minor increase in plasmid copy number but no mutations occurred in gyrA or parC.

Published: November 2018

AbstractAimsWhat happens in the early‐elderly ‘pretiree’ period potentially influences the divergent paths of healthy or unhealthy ageing. In this cross‐sectional study, we aimed to profile musculoskeletal health and lifestyle behaviours for men and women in their late‐fifties and sixties.Methods and resultsFor 482 participants from the Geelong Osteoporosis Study, we measured DXA‐derived relative appendicular lean mass (rALM), bone mineral density (BMD) at the femoral neck and percentage body fat mass (%BF). Low‐rALM and low‐BMD referred to sex‐specific T‐scores<‐1.0. Associations between exposures and low‐rALM and/or low‐BMD were explored using multivariable logistic regression. Three‐quarters of participants had high %BF, 98(20.3%) had low‐rALM, 202(41.9%) had low‐BMD and 63(13.1%) had both low‐rALM and low‐BMD. Eight‐two (17.0%) were very active and one‐third participated in sports/recreational activities. Most [n=416(87.8%)] met the recommended daily intake (RDI) for protein; only 119(25.1%) met the RDI for calcium. Less than 10% smoked and one‐third exceeded recommended alcohol intakes. Independent of age, weight and sex, greater %BF and sedentary behaviour increased the likelihood of low‐rALM; high‐alcohol consumption increased the likelihood of low‐BMD; and greater %BF increased the likelihood of low‐rALM and low‐BMD combined.ConclusionsOne‐half of participants had rALM and BMD in the normal range. Only a few were involved in resistance‐training or weight‐bearing exercise, despite having the capacity to be physically active. As sedentary lifestyles, excessive adiposity and high alcohol use were associated with low‐rALM and/or low‐BMD, we propose that these adverse factors be potential targets among pretirees to minimise their risk of entering old age with poor musculoskeletal health.

INTRODUCCIÓN: La deficiencia de glucosa-6-fosfato deshidrogenasa (dG6PD) es la enzimopatía hereditaria más frecuente en el mundo. La mayoría de los casos son asintomáticos y algunos llegan a padecer anemia hemolítica aguda, ictericia neonatal o anemia hemolítica crónica no esferocítica. En países de Asia y el Mediterráneo y con alta incidencia de malaria, se practica el tamiz neonatal para la dG6PD, pero no existe un consenso universal para su implementación. OBJETIVO: Describir los valores de la actividad de G6PD en papel filtro en recién nacidos, analizar la prevalencia y la repercusión en el número de localizaciones a efectuar en el programa de tamiz neonatal nacional.MATERIAL Y MÉTODOS: Estudio retrospectivo de los resultados del programa de tamiz neonatal de la Secretaría de Salud de México. Se analizó la actividad de la glucosa- 6-fosfato deshidrogenasa dependiendo del tiempo de tránsito (tiempo trascurrido desde la obtención de la muestra de sangre del talón del recién nacido hasta su llegada al laboratorio). Se analizó la prevalencia según la actividad enzimática residual.RESULTADOS: De 1,076,918 recién nacidos tamizados, 343,272 tuvieron tiempo de tránsito adecuado (≤ 6 días). La actividad enzimática desciende significativamente después de ese tiempo. La prevalencia nacional al nacimiento fue de 4.26%, con porcentajes máximos en Veracruz, Nuevo León y Tabasco (21,20 y 15%, respectivamente). CONCLUSIÓN: 4.26% de los recién nacidos en México tienen dG6PD; es decir, un caso por cada 23 tamizados, lo que implica un elevado número de sujetos para localizar y evaluar en los programas de tamiz neonatal y en las instituciones que llevan a cabo el seguimiento clínico.PALABRAS CLAVE: Glucosa 6-fosfato deshidrogenasa, deficiencia de glucosa 6-fosfato deshidrogenasa, tamiz neonatal, prevalencia.

Background: The diagnosis and management of acute coronary syndrome (ACS) have improved significantly over the past few decades; however, the recognition of myocardial ischemia still proves to be a dilemma for cardiologists. The aim of this study was to determine the role of hematological and coagulation parameters in the diagnosis and prognosis of patients with ACS.
Methods: This prospective study recruited 250 patients with ACS and 250 healthy controls. The diagnostic role of hematological and coagulation parameters was assessed by comparing the patients with ACS with the control group. The relationships between these parameters and mortality were determined by dividing the patients into 2 groups: Group A (discharged) and Group B (patients who died within 30 days of follow-up). Multivariate Cox regression analysis was performed to calculate the hazard ratio (HR).
Results: The mean age of the patients was 55.14±10.71 years, and 65.2% of them were male. Prothrombin time (P<0.001), activated partial thromboplastin time (P<0.001), mean platelet volume (MPV) (P<0.001), white blood cell (WBC) count (P<0.001), and red blood cell distribution width (RDW) (P<0.001) were significantly higher in the case group than in the control group. WBC count (P<0.001), RDW (P<0.001), and MPV (P<0.001) were significantly higher in the controls than in the case group. The Cox regression model showed that RDW above 16.55% (HR=6.8), MPV greater than 11.25 fL (HR=2.6), and WBC higher than 10.55×103/μL (HR=6.3) were the independent predictors of mortality.
Conclusion: In addition to being the independent predictors of short-term mortality, RDW, WBC, and MPV when used together with the coagulation profile may aid in the diagnosis of ACS in patients presenting with chest pain.
