Model-Based Diagnosis for Cyber-Physical Production Systems Based on Machine Learning and Residual-Based Diagnosis Models
Authors: Bunte Andreas , Stein Benno , Niggemann Oliver
Published: September 2019

This paper introduces a novel approach to Model-Based Diagnosis (MBD) for hybrid technical systems. Unlike existing approaches which normally rely on qualitative diagnosis models expressed in logic, our approach applies a learned quantitative model that is used to derive residuals. Based on these residuals a diagnosis model is generated and used for a root cause identification. The new solution has several advantages such as the easy integration of new machine learning algorithms into MBD, a seamless integration of qualitative models, and a significant speed-up of the diagnosis runtime. The paper at hand formally defines the new approach, outlines its advantages and drawbacks, and presents an evaluation with real-world use cases.
From Horn-SRIQ to Datalog: A Data-Independent Transformation That Preserves Assertion Entailment
Authors: Carral David , González Larry , Koopmann Patrick
Published: September 2019

Ontology-based access to large data-sets has recently gained a lot of attention. To access data efficiently, one approach is to rewrite the ontology into Datalog, and then use powerful Datalog engines to compute implicit entailments. Existing rewriting techniques support Description Logics (DLs) from ELH to Horn-SHIQ. We go one step further and present one such data-independent rewriting technique for Horn-SRIQ⊓, the extension of Horn-SHIQ that supports role chain axioms, an expressive feature prominently used in many real-world ontologies. We evaluated our rewriting technique on a large known corpus of ontologies. Our experiments show that the resulting rewritings are of moderate size, and that our approach is more efficient than state-of-the-art DL reasoners when reasoning with data-intensive ontologies.
Approximate Stream Reasoning with Metric Temporal Logic under Uncertainty
Authors: De Leng Daniel , Heintz Fredrik
Published: September 2019

Stream reasoning can be defined as incremental reasoning over incrementally-available information. The formula progression procedure for Metric Temporal Logic (MTL) makes use of syntactic formula rewritings to incrementally evaluate formulas against incrementally-available states. Progression however assumes complete state information, which can be problematic when not all state information is available or can be observed, such as in qualitative spatial reasoning tasks or in robotics applications. In those cases, there may be uncertainty as to which state out of a set of possible states represents the ‘true’ state. The main contribution of this paper is therefore an extension of the progression procedure that efficiently keeps track of all consistent hypotheses. The resulting procedure is flexible, allowing a trade-off between faster but approximate and slower but precise progression under uncertainty. The proposed approach is empirically evaluated by considering the time and space requirements, as well as the impact of permitting varying degrees of uncertainty.
Aspectos biológicos y ecológicos del oso de anteojos (Tremarctos Ornatus, Ursidae) en la zona andina de Ecuador y perspectivas para su conservación bajo el enfoque de especies paisaje
Authors: Sandoval-Guillén Pablo , Yánez-Moretta Patricio
Published: September 2019

El oso andino u oso de anteojos (Tremarctos ornatus) ha habitado Sudamérica por más de cinco millones de años, y es el único representante viviente de los osos de nariz corta, un grupo que habitó solamente en el continente americano. Dentro de Ecuador es considerado en peligro de extinción, principalmente debido a la fragmentación y pérdida de hábitats naturalesen la regiónandina, causada poractividades antrópicas productivas(ganadería y agricultura)y de extracción de recursos naturales. Este oso es un mamífero que necesita de grandes extensiones para poder alimentarse y buscar pareja. El oso andino es importante para las zonas que habita, principalmente el bosque andino y el páramo, debido a su eﬁciente rol como dispersor de semillas. En el presente trabajo se analizan aspectos de esta especie en Ecuador, utilizando el enfoque teórico de ’especies paisaje’ para proponer actividades en pro de la conservación de este mamífero y de los hábitats en los que se desarrolla. Este enfoque permite evaluar de forma sistemática la calidad del paisaje en términos de los requerimientos biológicos de una especie de interés (en este caso,Tremarctosornatus) y de los usos humanos del paisaje; de igual forma considera características del área de conservación como su variación.

Social Media as a Field of a Modern Teenager’s Socialization
Authors: Sobkin V.S. , Fedotova A.V.
Published: September 2019

The paper explores teenagers’ attitude towards social media: their opinion about functions, specifics, and content of the interaction. The analysis is based on the data of a questionnaire survey carried out by the staff of the Centre of Sociology of Education (Institute of Education Management of the Russian Academy of Education). The survey involved 2074 students of 5th, 7th, 9th and 11th grades of schools of the Moscow Oblast. The data obtained in the research reveal specific gender and age differences. In using social media male students aim at expanding their social contacts, whereas female students are more interested in its informational and educational functions. The interest in the topic of personal relationships increases with age. The data showed that use of social media depends on student’s social status: those with high status among classmates value interaction in social media for its “freedom”, while those who have low status in real life emphasize the possibility to have a different self—representation in social media. According to the survey motives and activity in social media of those adolescents who consider their profiles as ‘provocative’ or ‘explicit’ significantly differ from those who want to keep their real-life personality (p≤0,05 for all comparisons). The results allow us to conclude that to a modern adolescent social media is a social testing ground where they solve their age-related and social conflicts.

Authors: Sabella Scott A. , Bernacchio Charles P. , Boland Elizabeth A. , Schultz Jared C.
Published: September 2019

Newly adopted accreditation standards within rehabilitation counselor education require the assessment of knowledge, skills, and a set of characteristics known as professional dispositions (PDs). PDs may be regarded as individual characteristics like values, beliefs, attitudes, or interpersonal ways of being that influence professional behavior. Yet, this remains an abstract construct that eludes simple definition and measurement. The purpose of this article is to review existing literature related to PDs in order to assist rehabilitation counselor educators in understanding (a) the conceptualization and identification of PDs, (b) the assessment of PDs within a program evaluation process, and (c) contextual dynamics that may influence the assessment of PDs. To this end, the article explores existing PD definitions; common factors related to counseling outcomes; and the guiding philosophies, codes, and values for the field of rehabilitation counseling. Additionally, the role of PDs are discussed in relation to accreditation standards, the development of standardized instruments, student assessment, and program evaluation. Finally, the assessment of PDs are considered in relation to multicultural dynamics, students with disabilities, and distance education.

Evidence on the Effect of Position Change on Pressure Ulcer among Hospitalized Adult Patients in Ethiopia: Meta-Analysis and Systematic Review
Authors: Shibabaw Wondimeneh , Aynalem Yared Asmare , Yirga Tadesse
Published: September 2019

Background: Pressure ulcers (PU) aﬀect millions of people worldwide and always occur over bony areas of the body where pressure and tissue distortion is greatest. The national pooled prevalence of pressure ulcer remains unknown. Hence, the aim of this meta-analysis was to determine the effect of position change on pressure ulcer among hospitalized clients in Ethiopia. Methods: Studies were retrieved through search engines in PubMed, Scopus, WHO afro library, Google Scholar, Africa journal online, PsycINFO and web-science following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). Analysis was done using STATA version 14 software. We checked the between-study heterogeneity using the I2 and examined a potential publication bias by visual inspection of the funnel plot and Egger’s regression test statistic. The random-effect model was fitted to estimate the summary effects, odds ratios (ORs), and 95% confidence interval (CIs) across studies. Results: Out of the reviewing 401 studies, 7 studies fulfilled the inclusion criteria and were included in the meta-analysis. The estimated pooled prevalence of pressure ulcer in Ethiopia was 11.7% (95% CI (7.28, 16.13%)). Based on the subgroup analysis, the estimated magnitude of pressure ulcer was 15.89% (95% CI: 35.34, 54.04) among studies their sample size were greater than or equals to 250. Those clients who have position change during hospitalization were 85% less likely to develop pressure ulcer [(OR 0.15, 95%CI (0.06, 0.4)] than their counter part. Conclusion: The overall prevalence of pressure ulcer in Ethiopia was relatively high. Position change of the client during hospitalization had paramount benefit to reduce the burden of pressure ulcer. Therefore, policymakers could give special attention to minimize the magnitude of pressure ulcer in order to improve the overall quality of healthcare service. Further meta-analysis study is need to identify individual and health care service related factors to the occurrence of pressure ulcer.

Based on these revelations, the study presents recommendation for the adoption of ICT with the aim of minimizing cost, enhancing communication and managing infrastructure. Also recommends the need to support IT department within an organization, with essential equipment, in terms of man and machine, for better efficiency to employ the key of ICT Impact in Iraqi governmental oil companies.
When Green Infrastructure Turns Grey: Implications of Overdesign for Plant Water Stress
Authors: Tu Min-cheng , Caplan Joshua , Eisenman Sasha , Wadzuk Bridget
Published: September 2019

Overdesign is a common strategy used by green infrastructure (GI) designers to account for unexpected performance loss, but such a strategy can create undesirable plant responses if it decreases water availability. The seasonal and event-based stomatal conductance data of two woody plant species in a green infrastructure (GI) was analyzed. The GI is a tree trench composed of five tree pits (each one was planted with a tree) in an infiltration bed. Runoff collected from the street was supplied to the bottom of the infiltration bed, although the system never filled completely indicating there was capacity for more runoff than what was observed over 3 years and the infiltration bed was overdesigned. Between the two tree species, evidence suggested that the root system of London plane spread beyond the boundary of the GI system and reached a subsurface water source, while that of hybrid maple did not. London plane showed a slower response to water added in the tree pit soil, which can indicate the reduced dependence on GI soil water after plants have reached an alternative water source. Such reduction is not favored because it defeats the purpose of having plants in GI systems. Designs using root barriers, appropriate plant species selection, etc. are recommended to avoid unwanted root spread. This study also found that GI design relying on upward water movements should be avoided because such design creates a narrow capillary zone on top of a saturated zone, which does not encourage transpiration.
In Schizophrenia, PON1 Q192R Genotypes and/or Lowered Paraoxonase 1 (PON1) Enzymatic Activity are Significantly Associated with the Deficit Syndrome, Negative Symptoms, Formal Thought Disorders, Psychomotor Retardation, Excitation and Increased IgA Levels to Gram-Negative Microbiota

Published: September 2019

Background: Primary deficit schizophrenia (DS) is characterized by enduring negative symptoms and represents a qualitatively different disease entity with respect to non-deficit schizophrenia (NDS). No studies investigated the association between the enzyme paraoxonase 1 (PON1) and DS and its phenomenology. Methods: In this case-control study, Thai women and men, aged 18-65 years, were divided in DS (n=40) and NDS (n=40) and were compared to controls (n=40). PON1 activities against 4-(chloromethyl)phenyl acetate (CMPA) and phenylacetate were determined. Moreover, subjects were genotyped for their PON1 Q192R polymorphism and IgA levels responses directed to Gram-negative bacteria were measured. Results: DS is significantly associated with the QQ genotype and the Q allele as compared with NDS and controls. PON1 activities are significantly and inversely associated with negative symptoms, formal thought disorders, psychomotor retardation, excitation and DS. The presence of the Q allele is associated with increased IgA responses to Pseudomonas aeruginosa, Morganella morganii, and Pseudomonas putida as compared with RR carriers. Conclusions: The PON1 Q allele and lower PON1 activities especially against CMPA are associated with DS, indicating lowered quorum quenching abilities as well as lowered defenses against lipoperoxidation and immune activation. It is suggested that lowered PON1 activity in DS constitutes an impairment in the innate immune system which together with lowered natural IgM may cause lower immune regulation thereby predisposing towards greater neurotoxic effects of immune-inflammatory, oxidative and nitrosative pathways and Gram-negative microbiota.

Artificial Intelligence (AI) is the buzz of modern-day computing. On a daily basis, we are witnessing newer developments in the name of AI. AI is the conceptual depiction of near-humanly responses to a given problem/task. The modern technology built upon the fifth-generation computing is adding more AI capabilities for IT-enabled technologies. The real question here is to identify if the AI can go a long way without its roots i.e. neuroscience or some other disciplines of study can also be complementary for the future development of the AI-enabled technologies. This paper is a concept review paper for the importance of neuroscience for the development of AI systems.
Comparison of Management of Developmental Dysplasia of the Hip in a Pavlik Harness by Orthopaedic Surgeons, Orthopaedic Pediatricians, and Advanced Practice Providers
Authors: Bellevue Kate D. , Bompadre Viviana , Lindberg Antoinette W.
Published: September 2019

Developmental dysplasia of the hip (DDH) is common, with high success rates of treatment in a Pavlik harness for children less than 6 months old. We performed a retrospective review, analyzing the outcomes of patients with DDH managed in a Pavlik harness by orthopaedic surgeons, an orthopaedic-trained physician, and advanced practice providers (APPs). There was no significant difference among provider types in patients requiring operative procedures of any kind. A straightforward treatment of DDH can be performed by orthopaedic-trained pediatricians and APPs, with referral to an orthopaedic surgeon if the patient fails treatment in a Pavlik harness.
Nontraumatic First Rib Fractures Secondary to Opposing Muscle Contractions
Authors: Weis Jamie L.
Published: September 2019

While first rib fractures typically occur from direct traumatic injuries and have high rates of serious complications, nontraumatic first rib fractures are less common and encountered in young athletes. The mechanism for these nontraumatic fractures is thought to be due to sudden contractions of opposing muscle forces on a developing bone. Because of the biomechanics of the first rib’s opposing muscle attachments, first rib fractures should be considered in patients who report pain deep to the medial clavicle, even without a history of direct severe trauma.

Structure vibration under the influence of unsteady hydrodynamic forces caused by the flow around their surfaces can adversely affect durability and rupture life. Reducing the adverse effects of hydrodynamic forces is currently possible with the help of linked CFD and vibration calculations. However, for an adequate description of the associated processes one should use calculation models and approaches specific to the hydro-vibration problem. To justify and validate such approaches, an experimental model was developed and a series of structure excitation tests in water flow was carried out.

The model comprises two cylinders installed sequentially in water crossflow. Vibration levels, pressure and velocity fluctuations were measured in the tests as a functions of the flow velocity. The application of different non-intrusive measurement techniques was possible due to relatively simple test model construction which may be used for cross-validation and experimental uncertainty quantification.

Flow-structure interaction, caused by synchronization effect of the flow separation frequency (or it’s spectral components) and eigenfrequency of cylinder, was analyzed based on simultaneously measured data. The tests performed gave the information about dynamical characteristics of the flow and vibration parameters of cantilevered cylinders. The experimental results are used for identification of required accuracy of hydrodynamic forces calculation by CFD and validation of oneand two-way linked methods for flow excitation frequency calculation.

Published: September 2019

Controlling of parameters of manufactured transistors and interoperational controlling during their production are necessary conditions for production of competitive products of electronic industry. Traditionally for controlling of bipolar transistors the direct current measurements and registration of capacity-voltage characteristics are used. Carrying out measurements on alternating current in a wide interval of frequencies (20 Hz–30 MHz) will allow to obtain additional information on parameters of bipolar transistors. The purpose of the work is to show the possibilities of the method of impedance spectroscopy for controlling of differential resistance of p–n-junctions of the bipolar p–n–p-transistor in active mode.

The KT814G p–n–p-transistor manufactured by JSC “INTEGRAL” was studied by the method of impedance spectroscopy. The values of differential electrical resistance and capacitance for base–emitter and base–collector p–n-junctions are defi at direct currents in base from 0.8 to 46 µA.

The results of the work can be applied to elaboration of techniques of fi checking of discrete bipolar semiconductor devices.
Application of Magnetic Noise Method to Control the Mechanical Anisotropy of Ferromagnetic Materials
Authors: Busko V. N. , Osipov A. A.
Published: September 2019

Presence of anisotropy of the ferromagnetic materials' properties determines the need for its research and control, since it has a significant impact on the basic physicomechanical characteristics of details, products and constructions. The aim of the work was to experimentally investigate the possibility of using the magnetic noise method for non-destructive testing of mechanical properties of ferromagnetic materials particularly value of the coefficient of normal anisotropy Rn of sheet metal, mechanical stresses under elastic deformation of electrical steel and the anisotropy of the physical and mechanical properties of ferromagnetic materials.

Since the mechanical anisotropy is related to the magnetic anisotropy, the magnetic method of the Barkhausen effect (MBE) was used in its study, the informative parameters of which belong to the group of magnetic anisotropy. Comparison of the results of anisotropy evaluation on a set of samples of stamped sheet steel using the MBE with values Rn measured by the manufacturer showed their close match. This revealed the possibility of Rn level evaluation using the MBE. Device for circular rotation of the Barkhausen transducer on the sample surface and device for forming of elastic bending stresses in the sample were constructed. To study the magnetic anisotropy in various materials and the impact of elastic tensile and compressive stresses by bending on it using the MBE.

It has been found that the elastic deformation in samples of electrical steel leads to dramatic change of the magnetic noise level and the shape of the circular diagrams, taking into account the sign of the stresses generated in the sample. It was established that as a result of cold rolling in the production process, electrical steel samples have a pronounced texture due to the direction of rolled sheet. The created elastic stresses in the considered range practically do not change the texture (induced crystallographic anisotropy) after the material rolling.

The results can be useful for studying, monitoring and testing of anisotropy, crystallographic texture, structural heterogeneity of ferromagnetic materials in the form of sheet metal, sheet steel and coil steel, sheet metal forming and for solving other problems using the magnetic noise method in aboratory and workshop conditions.

Background To run an inventory of instruments which assess quality of care from the patients’ experiences in primary care, in the context of multi-disciplinary health-care centres and which appraise their measurement quality, taking into account the methodological quality of their validation studies. Method Systematic review using Medline, Pascal, PsycINFO, Google Scholar, Cochrane, Scopus and CAIRN. For each instrument identified, the level of evidence was assessed using the COnsensus-based Standards for the selection of health status Measurement Instruments (COSMIN) checklist; the appraisal of the psychometric quality of the measurement property using three possible quality scores and the best-evidence synthesis based on the number of studies, their methodological and psychometric quality, and the direction and consistency of the results. Details of the subscales used to capture patients’ experiences of primary care were extracted and synthesized by grouping them into 9 dimensions defined by the Institute Of Medicine (IOM). Results 29 articles describing 29 instruments were found. Constructs captured by the assessment tools included illustrated a diversity of conceptualizations of patients’ experiences of primary care. There was no clear consensus across the assessment tools included about what patient experience in primary care ought to measure. There is an overall lack of evidence of their measurement quality, either because validation is missing or because methods are poor. Conclusion Due to the lack of evidence, the choice for the most appropriate instrument is difficult. Improvement and validation of existing instruments, and the use of COSMIN-guidelines could help make evaluations more effective.

Published: September 2019

Aluminum-phosphate-sulfate (APS) minerals of the alunite supergroup are minor components of uranium-bearing copper ores from the Olympic Dam deposit, South Australia. They typically represent a family of paragenetically late replacement phases after pre-existing REE-bearing phosphates (fluorapatite, monazite, and xenotime). Characterization with respect to textures and composition allows two groups to be distinguished: Ca-Sr-dominant APS minerals that fall within the woodhouseite and svanbergite compositional fields; and a second REE- and phosphate-dominant group closer to florencite in composition. All phases nevertheless display extensive solid solution among end-members in the broader APS clan and show extensive compositional zoning at the grain-scale. Samples representative of the deposit (flotation concentrate and tailings), as well as those that have been chemically altered during the processing cycle (acid leached concentrate), were studied for comparison. NanoSIMS isotope mapping provides evidence that the APS minerals preferentially scavenge and incorporate daughter radionuclides of the 238U decay chain, notably 226Ra and 210Pb, both over geological time within the deposit and during ore processing. These data highlight the role played by minor phases as hosts for geologically mobile deleterious components in ores as well as during mineral processing. Moreover, Sr-Ca-dominant APS minerals exhibit preferential sorption of Pb from fluid sources, in the form of both common Pb and 210Pb, for the first time revealing potential pathways for 210Pb elimination and reduction from ore processing streams.

Published: September 2019

Low-calcium fly ash (LC-F) and high-calcium fly ash (HC-F) were used to synthesize corresponding zeolites (LC-Z and HC-Z), then for adsorption of Se(IV) in water. The results showed that c zeolites can effectively adsorb Se(IV). The optimal adsorption conditions were set at contact time = 360 min; pH = 2.0; the amount of adsorbent = 5.0 g·L−1; temperature = 25 °C; initial Se(IV) concentration = 10 mg·L−1. The removal efficiency of HC-Z was higher than the LC-Z after it had fully reacted because the specific surface area (SSA) of HC-Z was higher than LC-Z. The adsorption kinetics model of Se(IV) uptake by HC-Z followed the pseudo-second-order model. The Freundlich isotherm model agreed better with the equilibrium data for HC-Z and LC-Z. The maximum Se(IV) adsorption capacity was 4.16 mg/g for the HC-Z and 3.93 mg/g for the LC-Z. For the coexisting anions, barely affected Se(IV) removal, while significant affected it. Regenerated zeolites still had high capacity for Se(IV) removal. In conclusion, zeolites synthesized from fly ashes are a promising material for adsorbing Se(IV) from wastewater, and selenium-loaded zeolite has the potential to be used as a Se fertilizer to release selenium in Se-deficient areas.
Unusual behavior of MgFe2O4 during regeneration: desorption versus specific adsorption
Authors: Ivanets A. I. , Prozorovich V. G. , Roshchina M. Yu. , Srivastava V. , Sillanpää M.
Published: September 2019

The reusability of spent adsorbents is the most important characteristic for their practical application. The process of MgFe2O4 regeneration after methylene blue (MB) adsorption was studied. The effect of the nature (HCl, HNO3, and MgCl2) and the concentration (10−3–10−1 M) of regeneration agents was established. All the regeneration agents at 10−3 and 10−2 M had high efficiency and adsorption capacity recovery reached 80–90%, whereas for 10−1 M concentration the adsorption efficiency was in the range of 4.5–36.2%. It was shown that the concentration of desorbed MB was much less than what had been previously adsorbed and did not correlate with regeneration efficiency. The unusual behavior of MgFe2O4 during regeneration could be due to different mechanisms of regeneration by OH3+ and Mg2+ ions: (i) for acidic regeneration the main process was the non-specific adsorption of OH3+ ions in a diffusion layer and the substitution of adsorbed MB due to electrostatic forces; (ii) in the case of Mg2+ as a regeneration agent, there was specific adsorption due to the completion of a crystal lattice of MgFe2O4 nanoparticles by Mg2+ ions (according to the rules of Fayans-Pannet) with the formation of new Mg-OH adsorption sites and the super-equivalent adsorption of Mg2+ ions (according to DLVO (Derjaguin, Landau, Verwey, and Overbeek) theory) accompanied by a recharge of the MgFe2O4 surface. These phenomena of MgFe2O4 regeneration using Mg2+ ions must be taken into account in the theory and practice of adsorption.

Background and objectives

Survival after surgical repair for congenital heart disease has markedly improved; however, there are limited data on long-term ESKD and mortality during childhood.

Design, setting, participants, & measurements

We conducted an observational, population-based cohort study of children who had their first surgery for congenital heart disease within 10 years of birth. The study was conducted in Ontario, Canada, where residents have universal access to health care services. Each child who underwent surgical repair was matched to ten children from the general population who were similar in age, sex, index date, rurality, and neighborhood income. Primary outcomes of all-cause mortality and ESKD were reported until March 2015.

Results

We followed 3600 children with congenital heart disease for a median of 5.9 (interquartile range, 2.9–9.0) years after their surgical repair. Median age at first surgery was 150 (interquartile range, 40–252) days and 22% were low birth weight (<2500 g). During follow-up, 140 (4%) children who had surgery for congenital heart disease died and 52 (1%) reached ESKD. The cumulative incidence of death and ESKD at 1, 5, and 10 years was higher in children with surgical repair of congenital heart disease (death: 3%, 4%, and 5%, respectively; ESKD: 1%, 2%, and 2%, respectively) compared with the matched control population without any congenital heart disease (death: 0.06%, 0.10%, and 0.13%, respectively; ESKD: 0.00%, 0.02%, and 0.02%, respectively). The risk of ESKD and death increased with severity of congenital heart disease, with the highest risk in children with hypoplastic left heart syndrome and increased in children who had surgical repair of congenital heart disease compared with those without surgical repair.

Conclusions

The risk of mortality and ESKD is high in children who undergo surgical repair for congenital heart disease compared to the general population.

Two-Qubit Pure Entanglement as Optimal Social Welfare Resource in Bayesian Game
Authors: Banik Manik , Bhattacharya Some Sankar , Ganguly Nirman , Guha Tamal , Mukherjee Amit , Rai Ashutosh , Roy Arup
Published: September 2019

Entanglement is of paramount importance in quantum information theory. Its supremacy over classical correlations has been demonstrated in a numerous information theoretic protocols. Here we study possible adequacy of quantum entanglement in Bayesian game theory, particularly in social welfare solution (SWS), a strategy which the players follow to maximize sum of their payoffs. Given a multi-partite quantum state as an advice, players can come up with several correlated strategies by performing local measurements on their parts of the quantum state. A quantum strategy is called quantum-SWS if it is advantageous over a classical equilibrium (CE) strategy in the sense that none of the players has to sacrifice their CE-payoff rather some have incentive and at the same time it maximizes sum of all players' payoffs over all possible quantum advantageous strategies. Quantum state yielding such a quantum-SWS is called a quantum social welfare advice (SWA). We show that any two-qubit pure entangled state, even if it is arbitrarily close to a product state, can serve as quantum-SWA in some Bayesian game. Our result, thus, gives cognizance to the fact that every two-qubit pure entanglement is the best resource for some operational task.
Minha língua é minha pátria? A circulação de artistas “multiculturais” na cena dos festivais na cidade de Montreal (Canadá)
Authors: Gumes Nadja Vladi
Published: September 2019

Esse artigo traz os primeiros resultados de uma pesquisa de pós-doutorado realizado durante seis meses na cidade de Montreal, no Canadá, na McGill University, cujo foco principal é perceber a música como instrumento de inclusão de imigrantes. Nesse trabalho observamos o funcionamento dos festivais como parte do circuito para a circulação desses artistas com o objetivo de difundir sua arte criando um networkingcom produtores, empresários e jornalistas. Tentamos nesse texto trabalhar com a noção de cena musical (STRAW, 2005) em diálogo com cosmopolitismo estético (REGEV, 2013), pensando a música como a ferramenta midiática fundamental para a compreensão dos processos sociais contemporâneos nos espaços urbanos.
Simulacros urbanos e Madonna: a ambientação pós-moderna dos videoclipes
Authors: Gusmão Roney , Araújo Sérgio
Published: September 2019

A linguagem dos videoclipes apresenta características fortemente associadasà pós-modernidade, sobretudo por adensar jogos de imagem e contribuir para adesconstrução de hierarquias simbólicas. A carreira de Madonna no transcurso dosanos 1980 e 1990 serve de arquétipo para entendimento da arte pós-moderna,principalmente porque seus videoclipes imprimem a estética contemporânea emcenas urbanas, recrutadas como ambiência para sua arte. Interessa-nos, portanto,compreender a forma como sua obra coopera para a construção de simulacrosurbanos no referido período, traduzindo a construção sígnica da pós-modernidade.

Published: September 2019

Recentemente, a literatura econômica tem incorporado a produção artística, cultural e criativa àsamenidades urbanas, ou seja, o conjunto de características e atividades capazes de gerar externalidades positivassobre residentes e visitantes, elevando seu bem-estar. Do mesmo modo, a concentração da chamada “classecriativa” vem sendo reconhecida como uma vantagem comparativa de certas cidades, facilitando sua inserçãocompetitiva na “economia do conhecimento” e gerando efeitos multiplicadores internos à região ao induzir asubstituição de importações. Nessas análises, os trabalhadores culturais e criativos são entendidos como umaclasse de alta mobilidade no território, cujas decisões locacionais estariam relacionadas à capacidade de atração eretenção desses trabalhadores das regiões. Este artigo investiga essa hipótese para o Brasil, buscando responder aduas grandes questões: i) a probabilidade de migração desse grupo é diferente conforme a região de destino?;ii) asrazões individuais para a migração diferem das dos demais grupos de trabalhadores? São utilizados dadosindividuais do Censo Demográfico de 2010. Aspectos individuais das decisões migratórias são investigados combase em modelos multinomiais. Os resultados sugerem respostas positivas aos dois questionamentos.

We investigated the effect of disulfiram (DSF) on reproductive toxicity induced by subchronic exposure to cadmium (Cd). We examined the redox status and systemic testosterone changes in the testes and plasma of Cd-treated male Wistar rats. Rats were treated with 1 mg CdCl2/kg body weight (bw)/day (intraperitoneal administration) for 42 days; in the second experimental group, rats were given 178.5 mg DSF/kg bw/day by oral gavage for 21 days; in the third group, after administration of Cd for 21 days, DSF treatment was introduced on day 22 and lasted until day 42, with continuous Cd intake. Each experimental group had a matching control: untreated rats, rats that received for 21 days olive oil, the solvent for DSF; rats that started with olive oil intake from days 22-42. Exposure of rats to DSF modulated the oxidative status in the testes; thus, coexposure increased the Cd-induced reduction in total superoxide dismutase (tSOD), catalase (CAT), glutathione reductase (GR) and total glutathione-S-transferase (tGST) activities, and lowered the Cd-increased superoxide anion radical (O2 ??) and malondialdehyde (MDA) concentrations. DSF did not affect testosterone production diminished by Cd, as Leydig cells, once impaired by Cd, could not be reactivated by DSF.
