BCEdge: Blockchain‐based resource management in D2D‐assisted mobile edge computing
Authors: Zhou Ao , Sun Qibo , Li Jinglin 
Published: October 2019

SummaryIn recent decades, newly emerging mobile applications and services are becoming increasingly resource hungry and computation intensive. Portable size mobile devices fall short in providing such services. Cloud computing has been a core computation technology to provide visualized resources in a scalable way for mobile services. However, the unpredictable network transmission latency makes cloud computing not efficient enough for time‐sensitive mobile services, which requires major changes in underlying computing platform. Mobile edge computing is widely known as one of the novel technologies has emerged in recent years to address this issue. For being impractical to construct huge edge cloud in network edge, edge clouds can still be overloaded in rush time. Offloading to near‐user facilities using device‐to‐device (D2D) or other technologies becomes an augmentation approach. However, how to manage the facilities/resources effectively become a new issue. In this paper, we proposed a resource management scheme named BCEdge based on blockchain in D2D‐assisted mobile edge computing. BCEdge is a reliable scheme that operates in a distributed way to relieve the load of edge clouds. We illustrate the advantages and technical details of BCEdge using flow charts and interaction charts. The experiment results validate the effectiveness of our scheme. Finally, we discuss the possible future extensions.
Complex system governance: Concept, utility, and challenges
Authors: Keating Charles B. , Katina Polinpapilinho F. 
Published: October 2019

AbstractComplex system governance (CSG) is an emerging field focused on design, execution, and evolution of (meta)system functions that produce control, communications, coordination, and integration of a complex system. Ultimately, CSG explains system performance, prospects for continued system viability (existence), and future system sustainability. This paper explores three primary perspectives for CSG. First, following a brief introduction, a CSG overview is provided. Three underlying fields (systems theory, management cybernetics, and system governance), the derived model for CSG, and essential distinctions of CSG are developed. Second, the role and nature of CSG pathologies as aberrations from normal or healthy system conditions are developed. Pathologies are grounded in systems theory, and requisite variety is used to explain pathologies in complex system design, execution, or development impacting system performance. Third, challenges for balanced evolution of the CSG field are suggested. The paper concludes with suggestion for simultaneous development of science, engineering, and practice for CSG.

Published: October 2019

AbstractThe construction of an artificial peninsula extending the Monaco territory is destined to create an urban area of 6 ha. The preliminary works started end 2016, with the full completion of the maritime infrastructure by the end of 2020 and the delivery of the first buildings from 2022. The project requires the prefabrication of 18 caissons, which will constitute the maritime infrastructure of the extension at sea. Located at Marseille (200 km away from Monaco), the prefabrication of the caissons has been carried out by means of a floating structure (“caissonnier”) measuring 56 m long, 50 m wide, and 27 m high. During to the construction process, the caissons' rafts and the walls will be exposed to chlorides at early ages (5 days for rafts and 3 days for walls). The client's requirement was to implement a performance‐based durability design approach for all the concrete works of the maritime infrastructure. This approach implies to justify a 100‐years lifetime. The paper presents the methodology used to deploy a performance‐based design approach on this project. In particular, it details how the durability criteria have been set up in connection with the fib Bulletin 34 probabilistic models in order to target the 100‐years lifetime, but also the provisions (increased concrete cover, protective coating) for controlling chloride ingress at early age. In addition, the paper provides special attention in order to explain how the durability criteria are checked during the concrete production phase by the work site and the ready‐mix supplier.

Published: October 2019

AbstractAn experimental work on reinforced concrete flat slab specimens to test the efficiency of postinstalled bolts, as punching shear reinforcement in resisting vertical and cyclic horizontal loads, was conducted and is presented in this paper. The test protocol consisted in increasing horizontal drifts combined with constant vertical load until failure. Two different detailing solutions for the shear reinforcement were considered, one using a radial distribution around the column and another using a cross distribution, being the results compared with a previously tested reference specimen. The dimensions of the specimens were 4.25 x 1.85 x 0.15 m3. The test setup used for these tests was developed by the research team and simulates the boundary conditions with already recognized good results. Postinstalled steel bolts were proven to be an efficient solution for strengthening of existing structures, improving the structural behavior, and the punching resistance.
Novel analytical methods to study the fate of mycotoxins during thermal food processing
Authors: Stadler David , Berthiller Franz , Suman Michele , Schuhmacher Rainer , Krska Rudolf 
Published: October 2019

Abstract
Food processing can lead to a reduction of contaminants, such as mycotoxins. However, for food processing operations where thermal energy is employed, it is often not clear whether a reduction of mycotoxins also results in a mitigation of the toxicological impact. This is often due to the reason that the formed degradation products are not characterized and data on their toxicity is scarce. From the perspective of an analytical chemist, the elucidation of the fate of a contaminant in a complex food matrix is extremely challenging. An overview of the analytical approaches is given here, and the application and limitations are exemplified based on cases that can be found in recent literature. As most studies rely on targeted analysis, it is not clear whether the predetermined set of compounds differs from the degradation products that are actually formed during food processing. Although untargeted analysis allows for the elucidation of the complete spectrum of degradation products, only one such study is available so far. Further pitfalls include insufficient precision, natural contamination with masked forms of mycotoxins and interferences that are caused by the food matrix. One topic that is of paramount importance for both targeted and untargeted approaches is the availability of reference standards to identity and quantity the formed degradation products. Our vision is that more studies need to be published that characterize the formed degradation products, collect data on their toxicity and thereby complete the knowledge about the mycotoxin mitigating effect during food processing.
Correlation of 25-hydroxy vitamin D level with neonatal hyperbilirubinemia in term healthy newborn
Authors: Bhat Jehangir Allam , Sheikh Sajad Ahmad , Ara Roshan 
Published: October 2019

Background:
Neonatal hyperbilirubinemia is one of the common entities that lead to frequent hospital admission of newborn. There are many risk factors that, when present, can lead to increased chances of neonatal hyperbilirubinemia. It is essential to identify these risk factors that are involved in the increased incidence of neonatal hyperbilirubinemia because its incidence can be decreased by modifying them.

Objective:
To compare and determine any correlation of 25-hydroxy vitamin D levels of newborn and their mothers with the serum bilirubin level of newborn.

Methodology:
This was a case–control study conducted in a tertiary care hospital on 100 newborn who were divided into two groups (50 in each group) on the basis of their serum bilirubin level on the 5th day of life. Newborns having serum bilirubin levels in the physiological range were included in the control group, and newborns having serum bilirubin levels out of the physiological range and who needed treatment were included in the case group. The blood samples of both newborns and their mothers were collected on the 5th day and sent to the laboratory for serum bilirubin and 25-hydroxy vitamin D estimation.

Results:
The mean serum vitamin D level of cases was found to be lower than that of controls in both newborn and their mothers. A statistically significant difference was noted only between the vitamin D level of newborn but not in mothers when cases and controls were compared. Negative, statistically insignificant correlation was seen between vitamin D level and serum bilirubin in cases and controls. However, correlation of the vitamin D level of cases and their serum bilirubin was statistically significant, with a correlation coefficient of −0.335 and a p value of 0.0172.

Conclusion:
Term healthy newborn having hyperbilirubinemia, with serum bilirubin levels out of the physiological range, have significantly low vitamin D levels and show a statistically negatively correlation with neonatal hyperbilirubinemia (which is out of the physiological range). Thus, decreased vitamin D can be included in the list of risk factors for neonatal jaundice.

Published: October 2019

Introduction Optimal dispatch of emergency medical services relies on accurate time estimates of the various prehospital stages. Hoist rescue work time intervals performed by the search and rescue (SAR) helicopter service in Norway have not been studied to date. We aimed to describe the epidemiologic, operational, and medical aspects of the SAR service in southeast Norway. To complement the prehospital timeline, we performed simulated hoist operations. Methods We reviewed time and patient descriptors and medical interventions in hoist operations performed at a SAR base over 5 y. In addition, a simulation study measuring hoist rescue time intervals was performed. Data are presented as mean ± SD, except National Advisory Committee for Aeronautics (NACA) scores, which are presented as modes. Results There were 148 hoist operations performed during the study period, involving 180 patients. Time to take-off was 13 ± 7 min. There were 88 patients (49%) who were injured; 53 (29%) had a medical condition, and 39 (22%) were evacuees. The mode of the NACA score was 3. Forty-five patients (25%) had an NACA score of 4 to 6. Medical interventions were performed on 77 patients (43%) in 73 operations (49%). Nine patients (5%) were endotracheally intubated, and 1 thoracostomy was performed. The simulated rescuer access time was 4 ± 2 min, the simulated anesthesiologist access time was 6 ± 2 min, and the simulated hoist extrication time was 13 ± 2 min. Conclusions Hoist rescue was performed in 10% (n=148) of the SAR operations. New information about hoist extrication time intervals can improve rescue helicopter dispatch accuracy.
You Can Handle It: 3D Printing for Museums
Authors: Cooper Catriona 
Published: October 2019

OVERVIEW3D printing is a rapidly developing technology that has been championed as a revolutionary tool for the museums and heritage sector. Prints can provide innovative and engaging haptic experiences with objects in collections that cannot be handled, akin to craft replicas that have traditionally been employed. Large museums now regularly commission prints, yet evidence for the success of their deployment is largely anecdotal. This review considers how 3D prints have been utilized in museum contexts, with a focus on their successes and weaknesses as tools for public engagement.
ACTUARIAL APPLICATIONS OF WORD EMBEDDING MODELS
Authors: Lee Gee Y , Manski Scott , Maiti Tapabrata 
Published: October 2019

AbstractIn insurance analytics, textual descriptions of claims are often discarded, because traditional empirical analyses require numeric descriptor variables. This paper demonstrates how textual data can be easily used in insurance analytics. Using the concept of word similarities, we illustrate how to extract variables from text and incorporate them into claims analyses using standard generalized linear model or generalized additive regression model. This procedure is applied to the Wisconsin Local Government Property Insurance Fund (LGPIF) data, in order to demonstrate how insurance claims management and risk mitigation procedures can be improved. We illustrate two applications. First, we show how the claims classification problem can be solved using textual information. Second, we analyze the relationship between risk metrics and the probability of large losses. We obtain good results for both applications, where short textual descriptions of insurance claims are used for the extraction of features.
CSP and governance in emerging and developing country firms: Of mirrors and substitutes
Authors: Barkemeyer Ralf , Salignac Fanny , Argade Padmaja 
Published: October 2019

AbstractA recent debate in the international CSR literature has focused on the question whether CSR serves as a mirror or a substitute of country-level governance. Advocates of the mirror view highlight the role of country level institutions to drive corporate social performance (CSP) levels, whereas proponents of the substitute view find companies to become more active in light of governance gaps. We contribute to this debate by moving the focus to a sample of 264 emerging economy and developing country companies and by comparing the relationship between country-level governance and CSP based on three different CSP dimensions, namely, emissions, human rights, and community performance. Whilst we find corporate emissions performance and human rights performance to align more closely with the mirror view, there is some indication that corporate community performance—possibly traced back to the longstanding tradition of corporate philanthropy in non-Western contexts—instead acts as a substitute to fill institutional voids. We discuss implications of our findings for research and policymakers.
Kant on the Continuity of Alterations
Authors: Jankowiak Tim 
Published: October 2019

AbstractThe metaphysical “Law of Continuity of Alterations” (“LCA”) says that whenever an object alters from one state to another, it passes through a continuum of intermediate states. Kant treated LCA as a transcendental law of understanding. The primary purpose of the paper is to reconstruct and evaluate Kant’s three arguments for LCA. All three are found to be inadequate. However, a secondary goal of the paper is to show that LCA would have more naturally been construed as a regulative principle of reason (rather than a law of understanding). I conclude with some remarks about how this could work.
Soil characteristics drive Ficaria verna abundance and reproductive output
Authors: Kermack Justin P. , Rauschert Emily S. J. 
Published: October 2019

AbstractLesser celandine (Ficaria verna Huds.), an invasive plant from Europe, is becoming widespread in river valleys throughout the northeastern United States and the Pacific Northwest. Its high rate of asexual bulbil and tuber production creates dense infestations threatening native spring ephemerals. Ficaria verna abundance and reproductive output (seeds, bulbils, and tubers) were examined in invaded transects spanning a disturbance gradient away from a river. Site characteristics (photosynthetically active radiation [PAR], soil pH, moisture, texture, and nutrients) were quantified to examine their roles in plant abundance and reproduction. A larger-scale study examined random transects not specifically chosen based on F. verna infestations. Soil characteristics and slope were hypothesized to drive F. verna abundance and reproduction; we also hypothesized that reproductive output and biomass would be highest at intermediate distances from rivers, where disturbances are infrequent. Ficaria verna abundance and reproductive output varied considerably by site; soil characteristics, rather than landscape placement, appeared to drive plant abundance and reproduction. Lower percent sand was associated with significantly higher F. verna stem density and bulbil and tuber production. CEC was significantly negatively related to F. verna biomass and tuber counts. In the larger-scale survey, slope and PAR were significantly negatively related to F. verna presence and percent cover, respectively. Overall, these findings suggest that soil texture and slope can help explain higher abundance and reproductive outputs. However, reproductive output and biomass were not significantly greater at intermediate distances, contrary to expectations. We did not observe any seed production in any of the plots, although we did see a few plants with seeds outside our study area in the second year, demonstrating a near-complete reliance on asexual reproduction in these populations. This study expands on the current limited understanding of F. verna and can help management by identifying areas likely to support dense infestations.

Published: October 2019

AbstractThe Middle Draa Project (2015–18) is a pioneering survey of the archaeology of a c.200 km long valley at the northern edge of the Moroccan Sahara. Combining mapping from satellite imagery, field survey and trial excavation, the project has established a new baseline for the region's archaeological heritage. This paper concentrates on the main results in relation to the Protohistoric (Iron Age) phase, when the first steps towards sedentarisation and oasis agriculture appear to have been taken.
EAMENA training in the use of satellite remote sensing and digital technologies in heritage management: Libya and Tunisia workshops 2017–2019
Authors: Hobson Matthew S. 
Published: October 2019

AbstractThis article provides a brief summary of the aims, methods and results of a programme of training carried out by the EAMENA project in partnership with the Tunisian Institut National du Patrimoine and the Libyan Department of Antiquities. The focus was on the use of freely available satellite imagery for archaeological site identification and monitoring, on compiling and maintaining spatial databases - including the on-the-ground location of sites with the use of a GPS - and on the observation of patterns of preservation and threat within Geographical Information Systems to inform heritage management decisions at both regional and national levels. Three pairs of workshops took place in Tunis in 2017, 2018 and 2019, with interim support being given to participants by a Training Manager and Research Assistant based at the University of Leicester. The work was part of a larger scheme offered to heritage professionals across the Middle East and North Africa by the EAMENA project thanks to a grant received from the Cultural Protection Fund. In general this training has been very well received. Not only has it successfully achieved the propagation of desirable and much needed skills within partner institutions, it has also raised awareness of issues affecting the protection of cultural heritage within the broader community.
Pottery and trade at Euesperides in Cyrenaica: an overview
Authors: Zimi Eleni , Göransson K. , Swift K. 
Published: October 2019

AbstractThe excavations conducted at Euesperides between 1999 and 2007 under the auspices of the Society for Libyan Studies, London, and the Department of Antiquities, Libya, and jointly directed by Paul Bennet and Andrew Wilson, brought to light private houses and a building complex, industrial areas related to purple dye production and part of the city's fortification wall. Among the finds was a highly significant body of local, regional and imported pottery (from the Greek and Punic world, Cyprus, Italy and elsewhere), dated between the last quarter of the seventh and the middle of the third century BC, when the city was abandoned.This archaeological project adopted an innovative approach to the study of pottery from the site, based on the total quantification of the coarse, fine wares and transport amphorae. This was supplemented by a targeted programme of petrographic analysis to shed light on production centres and thus questions about the trade and the economy of ancient Euesperides. The pottery study by K. Göransson, K. Swift and E. Zimi demonstrated that although the city gradually developed a significant industry of ceramics, it relied heavily on imports to cover its needs and that imported pottery reached Euesperides’ sheltered harbour either directly from the supplying regions or most often through complex maritime networks in the Mediterranean which changed over time.Cooking pots from Aegina and the Punic world, mortaria, bowls, jugs and table amphorae from Corinth as well as transport amphorae from various centres containing olive oil, wine, processed meat and fish were transported to the city from Greece, Italy/Sicily, Cyprus and elsewhere. The so-called amphorae B formed the majority, while Corinthian, Aegean (Thasian, Mendean, Knidian, etc.), Greco-Italic and Punic were adequatly represented. Regarding fine wares, East Greek, Laconian and Corinthian are common until the end of the sixth century; Attic black-glazed, and to a lesser extend, black-figure and red-figure pots dominate the assemblages between the fifth and the mid-third centuries BC, while Corinthian, Italian/Sicilian and Punic seem to have been following the commodities flow at Euesperides from the fourth century BC onwards. Finally, Cyrenaican pottery and transport amphorae have been also identified at Euesperides implying a considerable volume of inter-regional trade.
