A game theory approach for cooperative control to improve data quality and false data detection in WSN
Authors: Casado‐Vara Roberto , Prieto‐Castrillo Francisco , Corchado Juan M. 
Published: August 2018

SummaryNew solutions are required for the management of heterogeneous distributed sensor networks in order to address the problem of data quality and false data detection in wireless sensor networks (WSNs). In this paper, we present a nonlinear cooperative control algorithm based on game theory. Here, a new model is proposed for the automatic processing and management of information in heterogeneous distributed WSNs. We apply our algorithm to a case study with the aim of improving the quality of temperature data collected from indoor surfaces by a WSN. Unlike the classic unsupervised methods, in the proposed algorithm, it is not necessary to define the number of clusters beforehand. Once the game reaches the game equilibrium, the resulting number of clusters can be used as input for the unsupervised classification analysis. Anomalous temperature values are corrected according to their neighborhood, without modifying the temperature clusters.

AbstractBright supramolecular fluorescent organic nanoassemblies (FONs), based on strongly polar red‐emissive benzothiadiazole fluorophores containing acidic units, are fabricated to serve as theranostic tools with large colloidal stability in the absence of a polymer or surfactant. High architectural cohesion is ensured by the multiple hydrogen‐bonding networks, reinforced by the dipolar and hydrophobic interactions developed between the dyes. Such interactions are harnessed to ensure high payload encapsulation and efficient trapping of hydrophobic and hydrogen‐bonding drugs like doxorubicin, as shown by steady state and time‐resolved measurements. Fine tuning of the drug release in cancer cells is achieved by adjusting the structure and combination of the fluorophore acidic units. Notably delayed drug delivery is observed by confocal microscopy compared to the entrance of hydrosoluble doxorubicin, demonstrating the absence of undesirable burst release outside the cells by using FONs. Since FON‐constituting fluorophores exhibit a large emission shift from red to green when dissociating in contact with the lipid cellular content, drug delivery could advantageously be followed by dual‐color spectral detection, independently of the drug staining potentiality.

AbstractBackgroundVery few studies have assessed the quality of life (QoL) of patients living with breast cancer in a resource‐poor setting like Nigeria. The aim of our study was to comprehensively examine the measures of QoL in breast cancer patients using the Functional Assessment of Cancer Therapy‐Breast (FACT‐B) version 4 in order to deepen the literature on QoL among breast cancer patients to include non‐Western/northern patient populations.Patients and methodsPurposive sampling of stable patients who attended general surgery clinics with histopathologically diagnosed breast cancer was done. Eligible patients were assessed using five domains of the FACT‐B questionnaire including: the breast cancer‐specific symptoms (BCS), emotional well‐being (EWB), functional well‐being (FWB), physical well‐being (PWB), and social & family well‐being (SWB). The questionnaire was administered in a face‐to‐face interview by trained research assistants. In addition, the five domains were compared among three different age categories, pre‐menopausal and post‐menopausal, and patients who have had surgery and chemotherapy alone. The SPSS (IBM Corp. Released in 2011. IBM SPSS Statistics for Windows, Version 20.0. Armonk, NY: IBM Corp.) and the Microsoft Excel (11. Corporation Microsoft, Redmond, WA, USA) were used for statistical analysis. Statistical significance was inferred when p <0.05.ResultsAmong the 60 enrolled participants, total score of the five domains (n = 144) was 74.59 ± 17.72, FACT‐G score (n = 108) was 53.49 ± 12.56, Trial outcome index (n = 112) was 49.20 ± 13.13, PWB (n = 28) was 10.95 ± 6.37, SWB (n = 28) was 18.41 ± 6.48, EWB (n = 24) was 6.98 ± 4.15, FWB (n = 28) was 17.15 ± 7.12, and the BCS (n = 36) was 21.10 ± 8.93. EWB was significantly less in post‐mastectomy patients on adjuvant chemotherapy (p = 0.031) and pre‐menopausal women (p = 0.041) as well as in patients less than 40 years when compared with patients more 50 years (p = 0.049).ConclusionsBreast cancer patients in resource‐poor countries have a profoundly impaired quality of life. This study showed significantly lower emotional well‐being domain scores in post‐mastectomy patients on adjuvant chemotherapy, pre‐menopausal women having breast cancer and in younger female patients. There is need to address this anomaly.

Published: August 2018

AbstractCommonly used discrete choice model analyses (e.g., probit, logit and multinomial logit models) draw on the estimation of importance weights that apply to different attribute levels. But directly estimating the importance weights of the attribute as a whole, rather than of distinct attribute levels, is challenging. This article substantiates the usefulness of partial least squares structural equation modeling (PLS-SEM) for the analysis of stated preference data generated through choice experiments in discrete choice modeling. This ability of PLS-SEM to directly estimate the importance weights for attributes as a whole, rather than for the attribute’s levels, and to compute determinant respondent-specific latent variable scores applicable to attributes, can more effectively model and distinguish between rational (i.e., optimizing) decisions and pragmatic (i.e., heuristic) ones, when parameter estimations for attributes as a whole are crucial to understanding choice decisions.

Published: August 2018

AbstractA decrease in the concentration of oxygen in the blood and tissues (hypoxia) produces important, sometimes irreversible, damages in the central nervous system (CNS) both during development and also postnatally. The present work aims at analyzing the expression of nerve growth factor (NGF) and p75 and the activation of TrkA in response to an acute normobaric hypoxic event and to evaluate the possible protective role of exogenous NGF. The developing chick optic tectum (OT), a recognized model of corticogenesis, was used as experimental system by means of in vivo and in vitro studies.Based on identification of the period of highest sensitivity of developmental programmed cell death (ED15) we show that hypoxia has a mild but reproducible effect that consist of a temporal increase of cell death 6 h after the end of a hypoxic treatment. Cell death was preceded by a significant early increase in the expression of Nerve Growth Factor (NGF) and its membrane receptor p75. In addition, we found a biphasic response of TrkA activation: a decrease during hypoxia followed by an increase −4 h later‐ that temporally coincide with the interval of NGF overexpression. To test the NGF ‐ NGF receptors role in hypoxic cell death, we quantified, in primary neuronal cultures derived from ED15 OT, the levels of TrkA activation after an acute hypoxic treatment. A significant decline in the level of TrkA activation was observed during hypoxia followed, 24 h later, by significant cell death. Interestingly, this cell death can be reverted if TrkA inactivation during hypoxia is suppressed by the addition of NGF.Our results suggest that TrkA activation may play an important role in the survival of OT neurons subjected to acute hypoxia. The role of TrkA in neuronal survival after injury may be advantageously used for the generation of neuroprotective strategies to improve prenatal insult outcomes.

AbstractA research study has been carried out to provide design guidelines for glass-fiber reinforced polymer (GFRP) guyed tower. Both material testing and theoretical analysis are involved. The tower examined in this study has 81 m in height with a uniform equilateral triangle cross section having sides of 450 mm. The tower supported by seven sets of guy wires oriented at 120°, each set consisting of three guy wires. The tower was assumed to be supported at the base by means of a pinned connection to provide full moment release. The tower was analyzed using the finite element ANSYS software and was designed to satisfy both the ultimate and the serviceability limit state requirements of the CSA-S37-01 Standard. The guyed tower was analyzed in static to evaluate the tower strength failure using several advanced failure theories. Modal analysis and full dynamic analysis using CSA-37-01 Standard were extensively performed to evaluate the vibration performance and to obtain an accurate dynamic response of the full-scale tower. The paper presents the results obtained from material testing and from a finite element, ANSYS models developed for the static and dynamic analysis of the multi-cells 81 m lightweight-guyed towers.Highlights The research = involved the analysis and the design of FRP guyed tower composed of individual cells fabricated from fiberglass matting bonded together to form an equilateral triangle. The layout, the dimensions of the tower and the thickness of the cell walls were determined from a finite element analysis. Fifteen coupons were fabricated and tested based on ASTM standards to evaluate the mechanical properties of the GFRP material. Several non-linear finite element models were developed to meet both the manufacturing constraints and strength requirements. Several non-linear finite element models were carried out for the static and dynamic analysis of an 81 m tower.
Mapping the Power Struggles of the National Green Tribunal of India: The Rise and Fall?
Authors: GILL Gitanjali Nain 
Published: August 2018

AbstractThis article documents the life-cycle of the National Green Tribunal of India (NGT). The NGT is officially described as a “specialised body equipped with necessary expertise to handle environmental disputes involving multi-disciplinary issues”—a forum offering greater plurality for environmental justice. Its international and national recognition promotes it as an exemplar for developing nations. The change management theory underpinning the paper is drawn from the work of Kurt Lewin and Edgar Schein, thereby allowing the analysis of competing internal and external forces affecting the NGT. There is a transmigration of theory and its application from one discipline to another social science: business psychology and management to law. The article identifies and addresses the crisis, and analyses the reasons and actions of the principal actors or forces interested in supporting the NGT and, on the other hand, those who are concerned, challenged, and affected by its growth, activities, and popularity.

ABSTRACTObjectivesWomen and men might experience psychological distress differently during a disaster. This study investigated gender differences in the factors associated with psychological distress among working-age people 1 to 2 years after the Great East Japan Earthquake.MethodsA cross-sectional household survey of victims who remained living in their homes was conducted between May and December 2012 in Ishinomaki City, Japan. Psychological distress was defined as a Kessler Psychological Distress Scale ≥5, and gender differences were examined using a logistic regression analysis.ResultsData were obtained from 2593 individuals, and 1537 participants were included in the analyses. Psychological distress was observed in 28.0% of the participants. Living in a household without a salaried income and a low frequency of leaving the house were associated with psychological distress among women. Young age, lack of occupation and no informational support were associated with psychological distress among men. Income change due to the disaster and health complaints were associated with psychological distress in both genders.ConclusionsFor women, stable household income and frequently leaving the house can be protective factors. For men, intervention focusing on young people, occupational support, and informational support may be useful. Income change after the disaster and health complaints may be risk factors in both genders. (Disaster Med Public Health Preparedness. 2019;13:487-496)
Mental health capacity building in refugee primary health care settings in Sub-Saharan Africa: impact, challenges and gaps
Authors: Echeverri C. , Le Roy J. , Worku B. , Ventevogel P. 
Published: August 2018

Background.In 2015, the United Nations High Commissioner for Refugees started a process of mental health capacity building in refugee primary health care settings in seven countries in Sub-Saharan Africa, ultimately aiming to decrease the treatment gap of mental, neurological and substance use (MNS) conditions in these operations. In 2015 and 2016, a specialized non-governmental organization, the War Trauma Foundation, trained 619 staff with the mental health gap action programme (mhGAP) Humanitarian Intervention Guide (HIG), a tool designed to guide clinical decision making in humanitarian settings.Methods.This paper describes the results of a process evaluation of a real-life implementation project by an external consultant, one and a half years after starting the programme.Results.The mhGAP-HIG capacity building efforts had various effects contributing to the integration of mental health in refugee primary health care. Facility-and community-based staff reported strengthened capacities to deliver mental health and psychosocial support interventions as well as changes in their attitude towards people suffering from MNS conditions. Service delivery and collaboration amongst different intervention levels improved. The scarcity of specialized staff in these settings was a major barrier, hindering the setting-up of supervision mechanisms.Conclusion.Mental health training of non-specialized staff in complex humanitarian settings is feasible and can lead to increased competency of providers. However, capacity building is a ‘process’ and not an ‘event’ and mhGAP trainings are only one element in a spectrum of activities aimed at integrating mental health into general health care. Regular supervision and continuing on-the-job training are in fact critical to ensure sustainability.
Study on Flexibility of Intracranial Vascular Stents Based on the Finite Element Method

Published: August 2018

ABSTRACTFlexibility is a particularly important biomechanical property for intracranial vascular stents. To study the flexibility of stent, the following work was carried out by using the finite element method: Four mechanical models were adopted to simulate the bending deformation of stents, and comparative studies were conducted about the distinction between cantilever beam and simply supported beam, as well as the distinction between moment-loading method and displacement-loading method. A complete process as implanting a stent including compressing, expanding and bending was also simulated, for analyzing the effects of compressing and expanding deformation on stent flexibility. At the same time, the effects of the arrangement and the number of bridges on stent flexibility were researched. The results show that: 1. A same flexibility index was obtained from cantilever beam model and simply supported beam model; displacement-loading method is better than moment-loading for simulating the bending deformation of stents. 2. The flexibility of stent with compressing and expanding deformation is lower than that in the initial form. 3. Crossly arranging the neighboring bridges in axial direction, can effectively improve the stent flexibility and reduce the flexibility difference in various bending directions; the bridge number, has proportional non-linear correlation with the stent rigidity as well as the maximum moment required for bending the stent.

Published: August 2018

ABSTRACTThe mechanical properties of thin-walled plate with close-packed film cooling holes are studied based on the equivalent solid material concept. The equivalent principals of the method of equivalent strain energy, homogenization theory and uniform static deformation are considered. A simplification method of square penetration pattern for pitch and diagonal direction loading is presented. The goodness of fit is calculated to determine the optimal method. The tensile deformation, bending deflection, rotation displacement and maximum Mises equivalent stress of simplification plate models are in good agreement with plate models with close-packed film cooling holes. For square penetration pattern for pitch direction loading, the equivalent errors of Mises equivalent stress are all less than 10% when the ligament efficiency is more than 0.6.

Published: August 2018

AbstractDespite growing interest in Indigenous entrepreneurship and entrepreneurial orientation, few studies bridge these two domains empirically. We address this gap by developing a model for exploring entrepreneurial orientation in Indigenous communities. We assess the possible dimensions of Indigenous entrepreneurship orientation in a qualitative study of Māori business owners in New Zealand. The findings suggest that Indigenous worldview and entrepreneurial ecosystem influences the entrepreneurial orientation of participants, leading to a continuum of Indigenous entrepreneurial orientation. The results have important implications for Indigenous entrepreneurship policy, practice and theory.

Published: August 2018

AbstractThis paper reports on an exploratory study into critical success factors as they are perceived by Māori small- to medium-sized enterprise (SME) owners in the Otago/Southland regions of New Zealand. We draw on interview responses from 11 Māori business owners and four representatives of SME support services. The aim of this study is to explore Māori SME characteristics in terms of the critical success factors that help or hinder the achievement of their business aspirations. The findings indicate three main thematic concerns: Māori SME owners’ perception of being Māori impacts on how they position themselves as a business; the regional business environment has particular features that impact in a particular way on Māori SMEs; and, notions of business strategy are culturally nuanced. We propose that a culturally constituted regional business support system will better enable Māori SMEs to achieve their aspirations.

AbstractMeasurements in the infrared wavelength domain allow direct assessment of the physical state and energy balance of cool matter in space, enabling the detailed study of the processes that govern the formation and evolution of stars and planetary systems in galaxies over cosmic time. Previous infrared missions revealed a great deal about the obscured Universe, but were hampered by limited sensitivity.SPICA takes the next step in infrared observational capability by combining a large 2.5-meter diameter telescope, cooled to below 8 K, with instruments employing ultra-sensitive detectors. A combination of passive cooling and mechanical coolers will be used to cool both the telescope and the instruments. With mechanical coolers the mission lifetime is not limited by the supply of cryogen. With the combination of low telescope background and instruments with state-of-the-art detectors SPICA provides a huge advance on the capabilities of previous missions.SPICA instruments offer spectral resolving power ranging from R ~50 through 11 000 in the 17–230 μm domain and R ~28.000 spectroscopy between 12 and 18 μm. SPICA will provide efficient 30–37 μm broad band mapping, and small field spectroscopic and polarimetric imaging at 100, 200 and 350 μm. SPICA will provide infrared spectroscopy with an unprecedented sensitivity of ~5 × 10−20 W m−2 (5σ/1 h)—over two orders of magnitude improvement over what earlier missions. This exceptional performance leap, will open entirely new domains in infrared astronomy; galaxy evolution and metal production over cosmic time, dust formation and evolution from very early epochs onwards, the formation history of planetary systems.

AbstractWhat impact do local candidates have on elections in single member district plurality electoral systems? We provide new evidence using data from a large election study carried out during the 2015 Canadian federal election. We improve on the measurement of local candidate effects by asking over 20,000 survey respondents to rate the candidates in their constituencydirectly. We present three estimates. We find that when all voters are considered together, local candidate evaluations are decisive for approximately 4 per cent of voters. Second, these evaluations are decisive for the outcome of 10 per cent of constituency contests. Third, when models are estimated for each constituency, we find significant evaluation effects for 14 per cent of candidates.
