Authors: Lee Hyukwoo , Lee Kyunghyun , You Kwanho 
Published: October 2019

Abstract
In this paper, we consider the stabilization and the estimate of quadrotor’s posture. Nowadays, as the interest in unmanned aerial vehicle (UAV) has increased, various application fields using UAV have appeared. The quadrotor is the most common type of UAV and many approaches to control the system have been studied. In real control environment, the system of quadrotor is affected by disturbance and measurement noise. Minimizing the effects of disturbance or measurement noise is important part. We propose the extended kalman filter (EKF) to reduce effectively the measurement noise of the nonlinear drones system and the integral sliding mode control (ISMC), a robust controller for the model uncertainty and disturbance. We show the proposed control performance through some simulations.

Published: October 2019

Abstract
The use of information technologies for the automotive transport and logistics management has opened game-changing opportunities for business, providing solutions to critical problems of sustainable development in turbulent environments. Today, the data for transport operations can be processed and used for the managerial decision-making, actually, on-line. However, despite abundance of TMSs on the market, many transport companies use them for solving operating management problems only. There are also lots of companies which do not use TMSs at all. Practice shows that managers of numerous transport companies have a little idea of how the records management data can be transformed into the awareness of improving efficiency of the transportation process. In our opinion it may be explained by the fact that different management levels use the knowledge from various domains, such as transport, IT, economic, and financial areas. Accordingly, the transformation of contemporaneous data into the managerial decisions requires an approach which is discussed in this paper using an example of introduction of TMS fuel consumption information subsystem.

Analysis of emerging disturbing factors on the descent vehicle with inflatable mechanical devices during the descent stage
Authors: Koryanov Vsevolod V. , Huanyu Sun 
Published: October 2019

Abstract
The movement of asymmetric descent vehicles, in contrast to the movement of symmetrical landing vehicles, has a number of features. The main of them consist in the emergence of such dynamic phenomena as progressive self-rotation, vibrational-rotational resonances, nutation-precession instability, auto-oscillations, and others. In this paper, the entire landing trajectory is divided into main stages of movement, and then an analysis of some of the most unfavourable variants of movement at each stage is given. The conclusion is about the worst options. This must be taken into account when designing such descent vehicles with inflatable structures.

Published: October 2019

Abstract
Wing-in-ground effect (WIG) crafts fly efficiently by exploiting the ground effect i.e. generating a notable rise in the lift-over-drag ratio when a three-dimensional wing approaches a large flat plane either water or ground surface. A successful WIG craft will create another mode of transportation categorise in between commercial airplanes and marine vessels. Hence, this paper presents a case study of Bixel Wing-In-Ground-Effect aerodynamic (Bixel WIG). The initial task is to simulate Bixel WIG aerodynamic using XFLR5 software. The craft configuration is a double wing flat aerofoil wave rider design with aspect ratio variation from 0.25 to 0.5 as in USA PATENT #5105898 C.BIXEL. Based on the result of the simulation, the design of the six seater double wing Bixel WIG is proposed. The design is benchmarked against Lippisch RHB X-114 and UH-18 SPW.
Experimental Analysis of Coir Fiber Sheet Reinforced Epoxy Resin Composite
Authors: Van Quy HO , Nguyen Song Thanh Thao 
Published: October 2019

Abstract
In recent years, the industrial demand for composite materials is increasing rapidly. However, most composite materials are produced from synthetic fibers and resins. As a result, the current production of composite materials still has many problems and the most worrying concern is the environment and human health. From those challenges, natural fiber composite is gradually becoming a worldwide research and development trend. Natural fibers are an abundant and renewable resource, so their cost is relatively low compared with other conventional fibers. They are eco-friendly, biodegradable and reduce the problem of solid waste production when used to replace non-degradable fillers. The objective of this study is to approach and learn about natural fiber composite, which is divided into two main stages. In the first one, we learn about natural fibers and matrixes of natural fiber composites. In the second stage, material testing experiments were performed on the coir fiber sheet reinforced epoxy resin composites to determine their mechanical properties as well as to find the mechanical properties of the coir fiber sheet using the rule of mixtures theory. The experimental results show that the non-split coir fiber sheet has the similar properties with ones of single coir fiber and results in a higher mechanical performance compared to the split coir fiber sheet. Additionally, the results show a medium stiffness, small density and low-cost composite material. Therefore, the further purpose of this study is to apply natural fiber composites in aeronautical engineering such as manufacturing small unmanned aerial vehicle.
The Design and Test of Elliptical-Circular Bicycle Sprockets
Authors: Lesmawanto Ardi , Chang Shinn-Liang , Ceng Sheng-Yuan , He Shin-Hao 
Published: October 2019

Abstract
Most people have different strength and frequency of the movements between the left and the right body side. In riding a bicycle with circular sprocket, the torques produced by the right leg and the left leg are generally different. Usually, the dominant leg exerts larger force than the non-dominant leg. Based on these conditions, in this paper, the application of elliptical-circular bicycle sprockets with the right size and position on the leg can provide more advantages compared to the ordinary circular sprocket in cycling. The crank torque comparisons reveal that the application of the elliptical-circular sprocket can reduce the torque produced by the right leg, and increase the torque produced by the left leg. This proves that the elliptical-circular sprocket is useful for balancing the force produced between the left leg and the right leg. Then, from the leg joint comparisons, the elliptical-circular sprocket can reduce the torque in the hips, knees, and the ankles. This means that the use of elliptical-circular sprocket can reduce the legs fatigue in riding a bicycle.
Global aesthetics
Authors: Nanay Bence 
Published: October 2019

Abstract
How does your aesthetic experience depend on what culture you grew up in? ‘Global aesthetics’ explains that much of it is due to the abundance of top–down influences on perception. But how do these top–down influences on perception work and what processes mediate them? Two mediating mechanisms are discussed—attention and mental imagery—which are exercised differently depending on what culture we have grown up in. As a result, perception depends on our cultural background. Global aesthetics is therefore about the geography of vision. It concludes that we should always be aware of the cultural perspective that we occupy and treat our aesthetic evaluations with humility.

Published: October 2019

Abstract
In a refractory brick manufacturing company a qualitative and quantitative determination of the sources of occupational exposure to polycyclic aromatic hydrocarbons (PAHs) was obtained in order to validate targeted hygiene measurements. The study included the assessment of PAHs contamination of work surfaces by wipe-sampling, cutaneous exposure by hand washing, contamination of personal protective equipments (gloves) by extraction in solvent, and airborne PAHs concentration in atmospheric samples. Biomonitoring was also carried out by measurement of urinary 1-hydroxypyrene (1-OHPU) in three groups of workers (packaging, production, and controls). The surface contamination sampling was performed in production, packaging, and in other departments (external area) in theory less contaminated by PAHs. Two different areas were identified within the production, one included surfaces that were regularly cleaned (A area) and one included data from non-cleaned surfaces (B area). To confirm the source of exposure, a clear correspondence was observed between the percentage of the single compounds in the binder and those measured in wipes and air samples. As far as the wipes are concerned, the concentrations of phenanthrene, anthracene, fluoranthene, pyrene, benzo(a)pyrene (BaP), and the total PAHs mixture were higher in the B area than the A area of production. The same happened between the A area and the other two departments. According to results of the statistical analysis, these differences were significant. These results were confirmed by the hand washing data and the analysis of PPE. On the other hand, a marked difference does not exist between the packaging department and the external area. In air samples, the differences were much less evident with only higher concentrations of anthracene and total PAHs between production as a whole and the other two departments. Biological monitoring showed 1-OHPU values significantly higher in production workers than in packaging workers. In conclusion, the analysis of the wipes demonstrated that the production B area has a higher surface contamination compared to the production A area and the packaging department. In the absence of a significant difference in air concentrations of PAHs between A and B areas, this is attributable to surfaces not subject to cleaning. Results confirm that the measurement of surface contamination represents a valid tool for the assessment of sources of exposure to PAHs in the workplace.
On Rhythms and Rhymes: Poetics of Identity in Postcolonial Italy
Authors: Ardizzoni Michela 
Published: October 2019

AbstractMusic, media and the arts in general have become a prime site of deep cultural contestation and polarization in Italy, generating unprecedented fractures in how Italian identity is conceived and lived. This article examines how the borders of Italian identity have been gradually stretched and challenged in the music of contemporary artists such as Mahmood, Ghali, and Amir Issaa. Through their beats, their lyrics, and, in the case of Issaa, his writing, these artists have given voice to a facet of Italianness that is rarely spotlighted in the media. In this sense, these cultural productions complicate the Italian collective memory by adding a layered understanding of contemporary identities, rooted in different cultures, speaking different languages, and embracing a way of being Italian that is looking to the future through the lens of the country’s colonial past.

Abstract

Background
Studies that correlate maternal antibodies with protection from influenza A or B virus infection in young infants in areas with prolonged influenza circulation are lacking.

Methods
We conducted a prospective, observational study to evaluate the effects of maternally transferred antibodies against influenza A and B viruses against laboratory-confirmed influenza in a cohort born over 24 months. Cord blood samples were retrieved at birth and infants were actively followed for the first 6 months of life. Nasal swabs were collected and tested for influenza A and B by reverse transcriptase–polymerase chain reaction whenever an illness episode was identified. Cord blood samples were tested by the hemagglutination inhibition (HAI) assay to viruses that circulated during the follow-up period.

Results
1162 infants were born to 1140 recruited women: 1092 (94%) infants completed 6 months of follow-up. Proportions of cord blood with HAI antibody titers ≥40 against A(H1N1), A(H3N2), B/Victoria, and B/Yamagata were 31%, 24%, 31%, and 54%, respectively. Only 4% of women had maternal influenza vaccination. Cord blood antigen-specific HAI titers ≥40 were found to correlate with protection from infection only for influenza B/Yamagata. No influenza B virus infection occurred in infants ≤60 days old. Proportional hazards analysis showed that a cord blood HAI titer of 40 was associated with 83% (95% confidence interval, 44–95%) reduction in the risk of influenza B/Yamagata infections compared with a cord blood titer &lt;10.

Conclusions
We documented that maternal immunity against influenza B/Yamagata was conferred to infants within the first 6 months of life.
Epigenetics in the public sphere: interdisciplinary perspectives
Authors: Dubois Michel , Louvel Séverine , Le Goff Anne , Guaspare Catherine , Allard Patrick 
Published: October 2019

AbstractDespite the high public interest in epigenetics, few scholars have empirically investigated the forms, reasons and consequences of the public circulation of epigenetics. Using an original database focusing on ‘lifestyle’ or ‘everyday’ epigenetics, this article aims to promote an open-minded and interdisciplinary dialogue between the public appropriation of epigenetics and the current scientific state of the art. It raises three main questions: Are there any specific modes of circulation of epigenetics in the general public? Why does epigenetics seem so appealing to the public? Within the public repertoire of epigenetics, is it possible to identify some specific knowledge claims and, if so, given the current state of the art, what is their degree of accuracy? The article argues that the social diffusion of epigenetics frequently carries on beliefs and misconceptions about genetics and epigenetics. The social life of epigenetics fuels a collective ‘illusion’ of control and empowerment on the basis of which new markets expand. More unexpectedly, this article underlines the emergence of a new scientific culture, i.e. the ‘scientifization’ of the cultural appropriation of epigenetics. Our analysis can inform the scientific community about the current and evolving state of the public representation of epigenetics and help it frame outreach activities.
‘I could have made those changes years earlier’: experiences and characteristics associated with receiving a prediabetes diagnosis among individuals recently diagnosed with type 2 diabetes
Authors: Somerville Mari , Burch Emily , Ball Lauren , Williams Lauren T 
Published: October 2019

Abstract

Background
Prediabetes increases the risk of developing type 2 diabetes (T2D). Improving diet quality is key in preventing this progression, yet little is known about the characteristics of individuals with prediabetes or the nutrition care they receive.

Objectives
This study aims to identify characteristics and experiences associated with receiving a prediabetes diagnosis prior to developing T2D.

Methods
A mixed methods study encompassed a quantitative subanalysis of participants with newly diagnosed T2D from The 3D Study, and semi-structured telephone interviews with a subsample of participants who were previously diagnosed with prediabetes. Interviews were thematically analysed and survey data synthesized using SPSS statistical software.

Results
Of the 225 study participants, 100 individuals were previously diagnosed with prediabetes and 120 participants were not. Those with prediabetes were less likely to be smokers (P = 0.022) and more likely to be satisfied with seeing a dietitian (P = 0.031) than those without a previous prediabetes diagnosis. A total of 20 participants completed semi-structured interviews. Thematic analysis revealed three themes: (i) experiencing a prediabetes diagnosis; (ii) receiving nutrition care during prediabetes and (iii) reflecting on the experience of receiving care for prediabetes versus T2D.

Conclusions
There are gaps in the current management of prediabetes in Australia. Low rates of prediabetes diagnosis and an ambiguous experience of receiving this diagnosis suggest an area of health service improvement. With no difference in diet quality between individuals with and without a previous prediabetes diagnosis, the nutrition care during prediabetes may be more important than the diagnosis itself in delaying the onset of T2D.

Authors: Deaner Matthew , Alper Hal S 
Published: October 2019

ABSTRACTAlthough only 6 years old, the CRISPR system has blossomed into a tool for rapid, on-demand genome engineering and gene regulation in Saccharomyces cerevisiae. In this minireview, we discuss fundamental CRISPR technologies, tools to improve the efficiency and capabilities of gene targeting, and cutting-edge techniques to explore gene editing and transcriptional regulation at genome scale using pooled approaches. The focus is on applications to metabolic engineering with topics including development of techniques to edit the genome in multiplex, tools to enable large numbers of genetic modifications using pooled single-guide RNA libraries and efforts to enable programmable transcriptional regulation using endonuclease-null Cas enzymes.

AbstractSTUDY QUESTIONCan endometrial stromal stem/progenitor cell markers, SUSD2 and CD146/CD140b, enrich for human myometrial and fibroid stem/progenitor cells?SUMMARY ANSWERSUSD2 enriches for myometrial and fibroid cells that have mesenchymal stem cell (MSC) characteristics and can also be induced to decidualise.WHAT IS KNOWN ALREADYMesenchymal stem-like cells have been separately characterised in the endometrial stroma and myometrium and may contribute to diseases in their respective tissues.STUDY DESIGN, SIZE, DURATIONNormal myometrium, fibroids and endometrium were collected from hysterectomies with informed consent. Primary cells or tissues were used from at least three patient samples for each experiment.PARTICIPANTS/MATERIALS, SETTING, METHODSFlow cytometry, immunohistochemistry and immunofluorescence were used to characterise tissues. In vitro colony formation in normoxic and hypoxic conditions, MSC lineage differentiation (osteogenic and adipogenic) and decidualisation were used to assess stem cell activity. Xenotransplantation into immunocompromised mice was used to determine in vivo stem-like activity. Endpoint measures included quantitative PCR, colony formation, trichrome, Oil Red O and alkaline phosphatase activity staining.MAIN RESULTS AND THE ROLE OF CHANCECD146+CD140b+ and/or SUSD2+ myometrial and fibroid cells were located in the perivascular region and formed more colonies in vitro compared to control cells and differentiated down adipogenic and osteogenic mesenchymal lineages in vitro. SUSD2+ myometrial cells had greater in vitro decidualisation potential, and SUSD2+ fibroid cells formed larger tumours in vivo compared to control cells.LARGE-SCALE DATAN/ALIMITATIONS, REASONS FOR CAUTIONMarkers used in this study enrich for cells with stem/progenitor cell activity; however, they do not distinguish stem from progenitor cells. SUSD2+ myometrial cells express markers of decidualisation when treated in vitro, but in vivo assays are needed to fully demonstration their ability to decidualise.WIDER IMPLICATIONS OF THE FINDINGSThese results suggest a possible common MSC for the endometrial stroma and myometrium, which could be the tumour-initiating cell for uterine fibroids.STUDY FUNDING/COMPETING INTEREST(S)These studies were supported by NIH grants to JMT (R01OD012206) and to ALP (F32HD081856).

Published: October 2019

Abstract
The patient was a 34-year-old woman who developed multiple post-myocarditis ventricular aneurysms with ventricular tachyarrhythmia. After implantation of an intracardiac defibrillator, she experienced multiple episodes of counter-shock. An electrophysiological study demonstrated an early excitation circuit entering the septal aneurysm with the right ventricular aneurysm as an exit. A surgical ablation of the re-entry and left ventricular plasty with scar resection was performed. The operation was performed under direct, epicardial electrophysiological guidance. A cryoablation was performed along the right ventriculotomy and the margin of the left ventricular aneurysm. The left ventricle was closed using endoventricular aneurysmorrhaphy and the right ventriculotomy was closed directly. No recurrence of ventricular tachyarrhythmia has been encountered.
Small, flat, and gray: Cryptic diversity in chthamalid barnacles in the global context of marine coastal biogeography (Cirripedia: Balanomorpha: Chthamalidae)
Authors: Wares John P 
Published: October 2019

AbstractIn the past 40 years, the ability to distinguish phenotypically similar species by using molecular methods has rapidly changed the study of taxonomy, biogeography, and community diversity. A cosmopolitan family of acorn barnacles, Chthamalidae Darwin, 1854, can be found on almost every non-boreal coast, with very similar habitat requirements, larval life histories, and external (test) morphologies among its species. Here I review how molecular methods have aided the description of new species as well as the characterization of phylogenetic diversity within species, and also broadened our understanding of the biogeography of this family. Multiple regional analyses have shown that the coastal habitat appears to drive diversity and diversification in generally similar ways regardless of location, while a global perspective allows us to identify regions and questions that merit further study. Variation in the spatial patterning of genomic diversity among species sometimes provides evidence as to how key life history parameters determine responses of species to ocean currents and forcing, thermal environments, and competition.
