A multisensor data fusion strategy for path selection in Internet‐of‐Things oriented wireless sensor network (WSN)
Authors: Kumar Shishupal , Chaurasiya Vijay Kumar 
Published: May 2018

SummaryTo give the complete description of an environment or to take a robust decision, a number of observations are collected and combined from multiple sensor nodes. The process of combining and analyzing the observations is called multisensor data fusion. The fusion is used to produce more consistent, accurate, and useful information rather than provided by any individual sensor node. Data fusion finds wide application in many areas of such as object recognition, wireless sensor network, image processing, environment mapping, and localization. Nowadays, the Internet of Things (IoT) utilizes wireless sensor network (WSN) as a necessary platform for data sensing and communication. For efficiency, data fusion is performed on the sensed sample collected by the sensor nodes. However, fusion of the network parameters is also essential to select an appropriate sensor node for the forwarding of data. Therefore, in this paper, we propose a multisensor data fusion (MDF) strategy that performs fusion of the collected network parameters like bandwidth and centrality for the selection of an appropriate path. Extensive simulations were made, and related results showed that our proposed scheme has a better performance compared with other schemes in our simulated scenarios.

AbstractArtichoke by‐products are a suitable source of health‐promoting ingredients for the production of dietary supplements and food additives. A pressurized hot water extraction (PHWE) was developed to recover caffeoylquinic acids (CQAs) and flavone glycosides (FLs) from agro‐industrial artichoke by‐products. The main factors influencing PHWE efficiency and CQA isomerization (temperature, numbers of cycles, modifier, and extraction time) were carefully studied and optimized by response surface design. The proposed PHWE procedure provides an exhaustive extraction of CQAs and FLs (recoveries: 93–105% and 90–105%) from artichoke external bracts and leaves of different cultivars (p > 0.05), without significant formation of artefacts generated by high temperatures. PHWE extracts showed CQA and FL levels (14–37 mg/g and 3–19 mg/g, respectively) comparable to commercial products and marked antioxidative effects (EC50 11–83 μg/mL) by cellular antioxidant activity assay in human hepatocarcinoma HepG2 cells. These results proved that PHWE is an excellent green technique to recover bioactive compounds from artichoke agro‐industrial residues.

AbstractAn optimization of temperature, time, and extracting agent concentration of pectin extraction from sunflower heads using sodium citrate and nitric acid (SP‐SC and SP‐NA) was carried out. At optimal conditions, the yield of extraction with nitric acid (SPO‐NA) was twofold greater than the corresponding with sodium citrate (SPO‐SC) (14.3 versus 7.7%, respectively). Regarding pectin structure, the galacturonic acid (GalA) content in both, SPO‐SC and SPO‐NA, was similar (∼85%). However, SPO‐NA showed lower molecular weight (Mw) (88.9 kDa) and neutral sugar content (4%) than SPO‐SC (464 kDa, 9%), indicating that nitric acid deeply degraded pectin structure. These differences derived into dissimilar behavior in their technological functionality. SPO‐SC showed higher viscosity and better emulsifying capacity than SPO‐NA, although any of them were able to stabilize the oil/water emulsion. Both sunflower pectins formed gels with Ca2+ (75 mg/g of pectin) at pH 3.0. However, when sucrose was added, the gels formed by SP‐SC and 20% sucrose presented the same hardness as those of SP‐NA with 40% sucrose. These results suggest that the pectin extracted with sodium citrate, an eco‐friendly agent, could be a promising ingredient, with good thickening and gelling properties.

Authors: Mayer Karl , Piesenberger Stephan , Penthor Stefan , Pröll Tobias , Hofbauer Hermann 
Published: May 2018

AbstractTwo perovskite type oxygen carriers, for the application in chemical looping combustion, called C14 and C28 are investigated. The composition of C14 is CaMn0.9Mg0.1O3−δ and CaMn0.775Mg0.1Ti0.125O3−δ for C28, respectively. Both oxygen carriers allow chemical looping with oxygen uncoupling (CLOU), they release oxygen under conditions with low oxygen partial pressure. The materials are tested in a 120 kWth pilot plant at TU Wien. Operating temperatures from 800 °C to 960 °C are investigated, further the influence of active inventory and air equivalence number is reviewed. In addition to the experiments in the pilot plant, particle analysis is performed. In total, the CLC operation for C14 was 29.5 h and 22.7 h for C28, resulting in 75 different operating points. Both oxygen carrier materials are able to fully convert the natural gas, used as fuel. A temperature dependency is noticeable for both, the best results are achieved at 960 °C, the highest investigated temperature. Both, C14 and C28 are able to release about 10 % of the total available oxygen via oxygen uncoupling. The performance of both oxygen carriers is strongly linked to the air equivalence number and the resulting amount of excess oxygen in the air reactor. Low oxygen partial pressures lead to incomplete fuel conversion.
The effect of thermochromic coatings of VO2 on the fire performance of windows
Authors: Ochoterena Raúl , Försth Michael 
Published: May 2018

SummaryThe effect of thermochromic coatings of vanadium dioxide (VO2) on the fire performance of windows was experimentally tested. Prototypes were subjected to radiant heat and the radiation transmitted through the specimens was measured as a function of time. The results indicate that windows coated with VO2 can reduce radiative heat transfer from fires and thereby also reduce or prevent fire spread. The results clearly show that VO2 coatings on BK7 substrates hinder approximately 30% of the transmission of radiation from fire sources when compared with the performance of uncoated windows. It is expected that VO2 will not be solely implemented for the purpose of increasing fire performance of windows, but it will rather provide a secondary positive effect if such windows are realized for energy‐saving purposes.

Published: May 2018

SummaryFire safety should consider not only the performance of the structure after the fire but also the behavior during the fire. The structural fire reliability performance of hybrid PVA fiber reinforced ferrocement (HFF) panels is experimentally determined based on its flexural characteristics and damage during the exposure to elevated temperatures. The residual compressive strength of 60 cubs was also tested after exposed to temperatures. In addition, 30 HFF panels were tested to evaluate their structural capacity by conducting an in‐situ binding test during the heating of up to 200°C, 400°C, 600°C, and 800°C, and compared with control samples tested at ambient (24°C) temperature condition. The main parameters investigated were the specimen thickness and the effect of using mineral admixtures (fly ash and silica fume) in the mortar mixtures. The results show a strength decline of both flexural and compressive strengths as temperature increases. The bending capacity at 800°C is reduced to about 90% of the ambient capacity only. In between the 2 temperatures, the reduction rate is found to be almost linear. A theoretical prediction of the moment capacity reduction shows a good agreement with the test results.
Medical service provider networks
Authors: Mougeot Michel , Naegelen Florence 
Published: May 2018

AbstractIn many countries, health insurers or health plans choose to contract either with any willing providers or with preferred providers. We compare these mechanisms when two medical services are imperfect substitutes in demand and are supplied by two different firms. In both cases, the reimbursement is higher when patients select the in‐network provider(s). We show that these mechanisms yield lower prices, lower providers' and insurer's profits, and lower expense than in the uniform‐reimbursement case. Whatever the degree of product differentiation, a not‐for‐profit insurer should prefer selective contracting and select a reimbursement such that the out‐of‐pocket expense is null. Although all providers join the network under any‐willing‐provider contracting in the absence of third‐party payment, an asymmetric equilibrium may exist when this billing arrangement is implemented.
Opening the Door for the Opportunistic Use of Interim Financing: A Critical Assessment of the EU Draft Directive on Preventive Restructuring Frameworks
Authors: de Weijs Rolef , Baltjes Meren 
Published: May 2018

AbstractThe European Union Draft Directive on a Preventive Restructuring Framework and Second Chance (the ‘Draft Directive’) provides rules for adopting reorganisation plans in order to avoid insolvency. The Draft Directive also provides rules on the related problem of interim financing. According to the Draft Directive, interim financing should be encouraged and not be made subject to claw back unless parties have committed fraud or acted in bad faith. The Draft Directive thereby fails to recognise that finance transactions are too diverse in nature to provide the company and its financial creditors with a transaction avoidance free period. If the Draft Directive is adopted in its current form, it will open the door for opportunistic use of interim financing by both debtors and professional lenders. It will allow debtors to make final bets with other people's money and will also allow for conduit pipe financing reducing the exposure of existing shareholders. Lenders will also be able to make opportunistic use of the rules, most notably in the form of cross‐collateralisation and aggressive loan‐to‐own strategies under the guise of interim financing.There are several possible solutions to the potential for opportunistic use. The courts could be involved ex ante. This would, however, turn the Draft Directive into a fully fledged court supervised procedure instead of the currently intended preventive restructuring procedure which avoids such court procedures. An alternative would be to simply take out the provisions on interim financing. Another possibility would be to limit the protection offered in the Draft Directive to cases of new security against new money necessary and used for the continuation of the business.

Curcumin down‐regulates IL‐17A mediated p53‐fibrinolytic system in bleomycin induced acute lung injury in vivo
Authors: Gouda Mahesh M. , Bhandary Yashodhar P. 
Published: May 2018

AbstractBleomycin (BLM) induced cellular damage causes inflammation in the alveolar compartment and impairment of fibrinolytic system leads to alveolar epithelial cell apoptosis. Here, we describe novel inflammatory pathway associated with p53‐fibrinolytic system and apoptosis of alveolar epithelial cells and pharmacological efficiency of curcumin against this action. In the present study we used C57BL/6 mice. The specific dose and time interval of curcumin were analyzed to assess the intervention. Experiments were designed to investigate the IL‐17A mediated modulation in the alveolar epithelial cell apoptosis and injury. Various techniques such as Western blot, RT‐PCR, Immunohistochemistry were used for this study. We observed that the BLM‐induced lung injury and its progression were successfully regulated by the effective dose and time intervention of curcumin. There was also decreased expression of chemokines, p53, and fibrinolytic components such as PAI‐1 and increased uPA, uPAR expression, and decreased alveolar epithelial cell apoptosis, which indicates the IL‐17A mediated novel inflammatory pathway. It is confirmed that the IL‐17A involved in the modulation of p53‐fibrinolytic system and epithelial cell apoptosis in BLM induced mice. The cross‐talk between the inflammatory, fibrinolytic, and apoptotic pathways were resolved by curcumin intervention. This pathway and intervention could serve as a modern therapy to resolve the complications to cure the lung injury and its progression.
Epidemiological analysis of maternal lipid levels during the second trimester in pregnancy and the risk of adverse pregnancy outcome adjusted by pregnancy BMI
Authors: Yue Chao‐Yan , Ying Chun‐Mei 
Published: May 2018

BackgroundPregnancy is accompanied by profound changes in lipid metabolism. We aimed to assess whether effects of second trimester body mass index and maternal lipid concentrations are associated with an increased risk of adverse pregnancy outcomes.MethodsWe investigated the serum levels of maternal lipids during the second trimester in pregnancy, and analyzed associations between the lipid levels and the risk of adverse pregnancy outcome. Seven hundred and seventy‐four pregnant women were enrolled in this study between February 2016 and June 2016. Multivariate logistic regression analysis was conducted to estimate the relative risk between maternal lipids and adverse pregnancy outcome.ResultsCompared with the control group, during the second trimester of pregnancy, BMI, TG, and Lp(a) were risk factors for gestational diabetes mellitus; middle trimester pregnancy BMI, Lp(a), and APO‐B were risk factors for pre‐eclampsia; second trimester BMI and TG/HDL‐C were risk factors for macrosomia; age and Lp(a) were uterine atony postpartum hemorrhage risk factors, while APO‐AI was a protective factor of uterine inertia and postpartum hemorrhage; second trimester BMI, TCH, Lp(a), and TG/HDL‐C were risk factors for fetal distress, while parity was a protective factor against fetal distress.ConclusionAbnormal blood lipid levels in pregnancy are significantly associated with GDM, pre‐eclampsia, and other adverse pregnancy outcomes.

Published: May 2018

ABSTRACTStandard treatments of adult acquired flatfoot deformity (AAFD) fail to correct associated dysfunction of the posterior tibial tendon (PTT). This study aimed to determine if a novel passive engineering mechanism (PEM) enhanced flexor digitorum longus (FDL) tendon transfer procedure would better restore physiologic PTT function to improve AAFD gait parameters compared to standard treatment. We evaluated the kinetic, pedobarographic, and kinematic effects of a pulley‐based PEM‐enhancement system utilizing a cadaveric flatfoot model and robotic gait simulator. FDL tendon force, FDL tendon excursion, regional peak plantar pressures, center of pressure, and foot bone/joint motions were quantified. Throughout the stance phase of gait, PEM‐enhancement significantly increased FDL tendon forces, resulting in gait cycle medial column unloading, lateral column loading, forefoot adduction, hindfoot inversion, and increased plantar flexion (p < 0.05). This proof‐of‐concept study demonstrated that an innovative PEM‐enhanced FDL tendon transfer procedure better restored physiologic PTT function, resulting in improved correction of the distinctive AAFD gait characteristics—medial column collapse, hindfoot eversion, and forefoot abduction. Clinical significance: Novel PEM‐enhancement of a FDL tendon transfer procedure holds promise as a method for improved treatment of AAFD. © 2018 Orthopaedic Research Society.

ABSTRACTPublications are an important tool to measure one's success and achievement in academia. They can help propel a career forward and move one into a position of leadership. The overall purpose of this study was to investigate changes in bibliometric variables, authorship, and collaboration trends in the Journal of Orthopaedic Research (JOR®), since its inception in 1983. A bibliometric analysis was completed for all manuscripts meeting the inclusion criteria (638), which were published throughout the inaugural year plus one representative year of each decade. Several parameters were investigated including numbers of manuscripts, authors, collaborating institutions/countries, references, pages, and citations; region of origin and gender of authors over time and by region were main focuses. Significant increases over time were observed in all bibliometric variables analyzed except in the number of pages and citations. There was an approximate 27% point increase for both female first and corresponding authors from 1983 to 2015. While this is most likely due to the increase in the number of women that have entered the field over time, similar increases in the percentage of women holding positions on the JOR editorial board or in leadership positions within in the field may have also contributed to improvements in gender parity. Understanding changes in publishing characteristics over time, by region, and by gender are critical, especially with the rising demands of publishing in academia. JOR has seen increase in most variables analyzed, including improvements in authorship by women in the field of orthopaedic research. © 2018 Orthopaedic Research Society.

The contrasting influences of incidental anger and fear on responses to a service failure
Authors: Su Lei , Wan Lisa C. , Wyer Robert S. 
Published: May 2018

AbstractCustomers’ disposition to register a formal complaint about an inferior product or poor service is often mediated by attributions of responsibility. However, the anger or fear that people happen to be experiencing for totally irrelevant reasons can also influence this disposition. Two field studies and four laboratory experiments indicate that when people feel angry at the time they encounter a service failure, they are more likely to blame the service provider for the failure and more likely to register a complaint. When they experience fear, however, they are uncertain about the cause of their misfortune and decrease their negative reactions relative to conditions in which fear is not experienced. The effects of these incidental emotions are evident both when a service failure is personally experienced and when it is only observed. These effects are eliminated, however, when individuals do not have the cognitive resources available to assess the reasons for the service failure and the conditions surrounding it.

Published: May 2018

AbstractThe development of wearable devices such as smart watches, intelligent garments, and wearable health‐monitoring devices calls for suitable energy storage devices which have matching mechanical properties and can provide sufficient power for a reasonable duration. Stretchable fiber‐based supercapacitors are emerging as a promising candidates for this purpose because they are lightweight, flexible, have high energy and power density, and the potential for easy integration into traditional textile processes. An important characteristic that is oftentimes ignored is stretchability—fiber supercapacitors should be able to accommodate large elongation during use, endure a range of bending motions, and then revert to its original form without compromising electrical and electrochemical performance. This article summarizes the current research progress on stretchable fiber‐based supercapacitors and discusses the existing challenges on material preparation and fiber‐based device fabrication. This article aims to help researchers in the field to better understand the challenges related to material design and fabrication approaches of fiber‐based supercapacitors, and to provide insights and guidelines toward their wearability.

AbstractAimTo explore the experiences with healthcare received by people living with chronic nonmalignant pain in Norway.DesignA descriptive and explorative qualitative design.MethodsA total of 18 individual semistructured interviews was conducted in 2015. Qualitative content analysis was applied.ResultsThe findings revealed challenges related to a multifaceted pain condition. Participants described interactions with a supportive health care where being listened to, believed in and experiencing mutual trust were emphasized. When interactions with healthcare professionals made the participants feel insignificant, they found it difficult to express their needs, which seemed to reinforce practical difficulties and unfulfilled expectations and make them lose hope in their recovery. This implies the importance of a holistic understanding of and support for more person‐centred practice to accommodate patients' expectations and expressed needs. Here, the nurses have an essential role in having a positive impact on future healthcare services.
