Authors: Li Jiaqiang , Li Sha , Liu Qing , Yin Chen , Tong Lianming , Chen Changguo , Zhang Jin 
Published: March 2019

AbstractGraphyne (GY) is a new type of carbon allotrope, which is viewed as a rapidly rising star in the carbon family referred to as 2D carbon allotropes due to its extraordinary properties. Considering the dynamic nature of the alkyne metathesis reaction, a hydrogen‐substituted graphyne (HsGY) film is successfully synthesized on a gas/liquid interface using 1,3,5‐tripynylbenzene (TPB) as the precursor. The synthesized HsGY film is used as a sulfur host matrix to be applied in lithium–sulfur batteries (LSBs). The HsGY@S electrode is prepared using S8 as sulfur source and presents excellent electrochemical performance.

AbstractCryopreservation is essential to effectively extend the shelf life of delicate biomaterials while maintaining proper levels of cell functions. Cryopreservation requires a cryoprotective agent (CPA) to suppress intracellular ice formation during freezing, but it must be removed prior to clinical use due to its toxicity. Conventional multistep CPA loading and unloading approaches are time consuming, often creating osmotic shocks and causing mechanical injuries for biological samples. An efficient surface‐acoustic‐wave‐ (SAW‐) based lab‐on‐a‐chip (LoC) for fast loading and removal of CPAs is presented here. With the SAW‐based multistep CPA loading/removal approach, high concentration (3 m) CPA can be successfully loaded and removed in less than 1 min. Results show that the technique causes the least harm to umbilical cord matrix mesenchymal stem cells as compared to conventional method, and an average of 24% higher cell recovery rate is achieved, while preserving the integrity and morphology of the cells. This device is the first of its kind to combine high loading/unloading efficiency, high cell viability, and high throughput into one LoC device, offering not only a more efficient and safer route for CPA loading and removal from cells, but also paving the way for other cryopreservation‐dependent applications.
Comparative metaphysics: Evolutionary and ontogenetic roots of essentialist thought about objects
Authors: Rakoczy Hannes , Cacchione Trix 
Published: March 2019

How do animals and young children see the world around them in its most basic structure, and how do such world‐views develop over time? These are questions of what could be called comparative and developmental metaphysics. The present paper gives an introduction to this newly emerging field of research. Special emphasis is put on thinking about the world as made up of discrete and enduring objects as the most fundamental form of objective thought. The paper discusses whether language is necessary for such basic forms of objective thought, and whether thinking about objects, in turn, may lay a foundation for psychological essentialism.This article is categorized under:Cognitive Biology > Evolutionary Roots of CognitionPsychology > Comparative Psychology

Published: March 2019

AbstractSocial behaviour in public spaces has changed over the time and has become attractive to all those involved in designing people’s spaces. Communities in different countries in Europe have shown more and more interest and various activities have started to shape the public spaces all round the world. The main objective of the chapter is to review development of the methodologies that have been used to analyse public spaces worldwide and to summarize their requirements and conditions to suggest how they can be applied in order to analyse the relationship between people and spaces, with the aim to boost the active participation of people in design process. The chapter describes the methodologies using ICTs, especially e-participation, mobile technologies, GIS systems, or on the methodologies increasing the attractiveness of the public open spaces for citizens and visitors (laser holograms, QR codes, interactive boards, online and interactive maps, questionnaires and social interaction, etc.). Information technology offers new potentials of citizen participation and provides a communication platform, which suppresses a barrier of non-professionalism, allowing for distant contacts and enabling participatory process management. Users, accustomed to communicating through ICT also in public spaces, feel by using this tool more anonymous and less harassed to express their opinion. Not only ICT are important in the 21st century society, but also new ways of social media, which are accessible/open to use for larger group of people. The institutions or municipalities could use them as semi-official information platform, public open discuss forums or resource of the public initiatives.
Liveable Open Public Space - From Flaneur to Cyborg
Authors: Djukic Aleksandra , Vlastos Thanos , Joklova Viera 
Published: March 2019

AbstractOpen public spaces have always been key elements of the city. Now they are also crucial for mixed reality. It is the main carrier of urban life, place for socialization, where users rest, have fun and talk. Moreover, “Seeing others and being seen” is a condition of socialization. Intensity of life in public spaces provides qualities like safety, comfort and attractiveness. Furthermore, open public spaces represent a spatial framework for meetings and multileveled interactions, and should include virtual flows, stimulating merging of physical and digital reality. Aim of the chapter is to present a critical analysis of public open spaces, aspects of their social role and liveability. It will also suggest how new technologies, in a mixed reality world, may enhance design approaches and upgrade the relationship between a user and his surroundings. New technologies are necessary for obtaining physical/digital spaces, becoming playable and liveable which will encourage walking, cycling, standing and interacting. Hence, they will attract more citizens and visitors, assure a healthy environment, quality of life and sociability. Public space, acting as an open book of the history of the city and of its future, should play a new role, being a place of reference for the flaneur/cyborg citizen personal and social life. The key result is a framework for understanding the particular importance of cyberparks in contemporary urban life in order to better adapt technologies in the modern urban life needs.
Exploring the Concept of Cyberpark: What the Experts Think

Published: March 2019

AbstractThe chapter aims to provide a contextualisation of the cyberpark concept as this is perceived by a wide range of experts in public space and information technologies. To do so it makes use of a questionnaire survey conducted with the participants of the CyberParks COST Action, which collected their views on a number of aspects concerning both the mediated and the not mediated public open spaces, such as: their elements and qualities, the facilities they should offer, the activities they should facilitate, the type of space and location that are most suitable to accommodate them, their appropriate size and manner for their development, their target user group and other aspects of their configuration. The analysis brings out the commonalities and differences in experts’ views regarding the mediated and the not mediated public open spaces, and, as such, it contributes to specify further the cyberpark concept, mapping out its characteristics and dimensions. This should enrich the ongoing dialogue within the literature and facilitate interactions between relevant, yet fragmented, scientific disciplines in the area to inform the production and appropriation of both mediated and the not mediated public open spaces.
Socio-Spatial Practices: An Introduction and Overview
Authors: Kenna Therese , Maksymiuk Gabriela 
Published: March 2019

AbstractWe are now firmly in a digital era and technologies are ever-present. Since the introduction of new digital technologies and ICTs, such as smart phones, the literature has presented some contrasting analyses of the socio-spatial practices and impacts that have resulted from the uptake of new technologies in urban public spaces. On one hand, there is a particular set of debates that have expressed concerns that the introduction of digital technologies, especially personal ICTs, is leading to a greater withdrawal from urban public spaces.
People - Space - Technology: An Ethnographic Approach
Authors: Menezes Marluci , Arvanitidis Paschalis , Kenna Therese , Ivanova-Radovanova Petja 
Published: March 2019

AbstractCyberParks aims at advancing knowledge on the relationship between information and communication technologies and the socially sustainable production and usage of public open spaces. Such research necessitates a solid methodological base. Urban ethnography brings together a number of perspectives and approaches to deal with cultural and social aspects of urban life, and as such it is able to provide an integrated methodological framework for the study of technology-public space relationship. The ethnographic approach means, by definition, an in-depth, micro-scale look at the phenomena under concern. However, the technological dimension makes the relationship between people and space more complex. This is not simply because an additional layer of analysis is added; it comes as a result of the emergence of multiple connections between the real and the virtual. From an ethnographic perspective, this requires the researcher to capture, explore and understand the cyber-social phenomena and dynamics in a multifaceted, hybrid, triangulated and cross-referenced way. This makes ethnographic research much more complicated but more interesting as well. The current chapter attempts to outline such an analytical framework to guide empirical research on the issues. This framework draws on the public space literature and adds the technological dimension brought in by the CyberParks project. We argue that this enriches the ethnographic approach providing a more integrated framework for the analysis of the relationship between people, space and technology.
JOINT LIFE INSURANCE PRICING USING EXTENDED MARSHALL–OLKIN MODELS
Authors: Gobbi Fabio , Kolev Nikolai , Mulinacci Sabrina 
Published: March 2019

AbstractIn this paper we suggest a modeling of joint life insurance pricing via Extended Marshall–Olkin (EMO) models and related copulas. These models are based on the combination of two approaches: the absolutely continuous copula approach, where the copula is used to capture dependencies due to environmental factors shared by the two lives, and the classical Marshall–Olkin model, where the association is given by accounting for a fatal event causing the simultaneous death of the two lives. New properties of the EMO model are established and applied to a sample of censored residual lifetimes of couples of insureds extracted from a data set of annuities contracts of a large Canadian life insurance company. Finally, some joint life insurance products are analyzed.
Management of the Invasive Shrub Amur Honeysuckle (Lonicera maackii) for the Endangered Perennial Wild Dill (Perideridia americana)
Authors: Loeb Robert E. , Peters Will , Ward Steve 
Published: March 2019

AbstractRadnor Lake State Natural Area in Nashville, TN, has cedar glades that contain the endangered perennial herb wild dill [Perideridia americana (Nutt. ex DC.) Rchb.] and the invasive shrub Amur honeysuckle [Lonicera maackii (Rupr.) Herder]. This research examined whether L. maackii treatment in the Radnor Lake State Natural Area cedar glades is followed by an increase in P. americana plants. A grid of 60 adjacent 2 m by 4 m plots was placed in five cedar glades to encompass the P. americana population. With great care to protect P. americana, the annual treatment for L. maackii was to pull plants ≤1-m tall from the ground; and to cut stems >1-m tall and then treat the stumps with glyphosate. The t-tests of means for the log natural of the number of plants in the 60 plots (significance level of P-value = 0.05) were used to compare pretreatment L. maackii and P. americana counts with posttreatment counts in 2018 and P. americana counts at leaf out and flowering in 2018. The L. maackii population was significantly smaller (P-value < 0.001) in 2018 than pretreatment at all five sites. When pretreatment in 2014 and 2015 was compared with posttreatment in 2018 for the P. americana populations, the increases were significant at the Cheek, Harris 2, Hideaway, and Norfleet sites, but the increase at East Hall Farm was not significant. White-tailed deer (Odocoileus virginianus Zimmermann) trampling was the explanation given for the decreases in P. americana from leaf out to flowering at all five sites in 2018. Browsing was evident only at Hideaway, which had a greater loss for P. americana from leaf out to flowering in 2018 than the combined losses for the Cheek, East Hall Farm, Harris 2, and Norfleet sites. The research informed the creation of adaptive management decisions regarding monitoring and treatment of the invasive species L. maackii for an endangered species.

ABSTRACTMultiple studies on regional glacier mass balance in the Pamir Mountains have been conducted using the geodetic method, but they were rarely extended to the period before 2000. In this study, we used KH-9 imagery acquired in 1975 to generate the historical DEM for the central Pamir, and then obtained the glacier elevation change by comparing this with the SRTM C-band DEM. The penetration depth of the C-band radar was corrected for different glacier surfaces, i.e. 2.96, 1.68 and 0 m for firn/snow cover, bare ice and debris-covered areas, respectively. The final results suggest that the central Pamir glaciers, overall, experienced a near-zero mass balance of −0.03 ± 0.24 m w.e. a−1 for 1975–99. Due to glacier surge activity, the elevation change patterns of individual glaciers were highly variable, and their mass balances varied from −0.12 ± 0.26 to 0.63 ± 0.20 m w.e. a−1. The mean mass budgets of the surge-type glaciers and non-surge-type glaciers were 0.03 ± 0.14 and −0.05 ± 0.28 m w.e. a−1, respectively. Concurring with previous studies, we conclude that the central Pamir glaciers may have been in a state of approximately balanced mass budget or slight mass deficit from the mid-1970s to the mid-2010s.

AbstractWe report comprehensive rock-magnetic and archaeointensity investigations from 21 well-constrained pottery fragments from the Catamarca province of northwest Argentina. The absolute ages of the studied sites are ascertained by several high-quality radiometric ages and range between 1940 to 114014C yr BP. Magnetic mineralogy experiments indicates that the remanence is carried by thermally stable Ti-poor titanomagnetites. Forty-seven samples belonging to 11 out of 98 studied potsherds yielded reliable absolute intensity determinations judging from the quality parameters associated with the Thellier double-heating experiments. Moreover, we analyzed the available absolute geomagnetic intensities associated with the radiometric ages to construct the first intensity paleosecular variation curve (PSVC) for South America using thermoremanent magnetization carried by burned archaeological artifacts obtained in the present investigation and 79 other selected archaeointensities (out of 213 published in the literature). The dataset is used to build the PSVC reference curve by combined bootstrap and temporal P-spline methods. The variation curve shows significant differences with the global prediction model SHA.DIF.14k mainly based on the GEOMAGIA database. This intensity PSVC curve shows reasonably good agreement with paleosecular variation curves for Europe between 850 through 1150 BC and for Asia between 1000 and 1500 BC. This regional curve may be used as most reliable archaeomagnetic dating tool for the major part of South America (Peru, Brazil, Argentina, Chile, and Bolivia) for the last two millennia.
Three-dimensional study of vestibular anatomy as it relates to the stapes footplate and its clinical implications: an augmented reality development

Published: March 2019

AbstractBackgroundThe anatomy of the membranous labyrinth within the vestibule has direct implications for surgical intervention. The anatomy of the otoliths has been studied, but there is limited information regarding their supporting connective tissue structures such as the membrana limitans in humans.MethodsOne guinea pig and 17 cadaveric human temporal bones were scanned using micro computed tomography, after staining with 2 per cent osmium tetroxide and preservation with Karnovsky's solution, with a resolution from 1 µm to 55 µm. The data were analysed using VGStudio Max software, rendered in three-dimensions and published in augmented reality.ResultsIn 50 per cent of ears, the membrana limitans attached directly to the postero-superior part of the stapes footplate. If attachments were present in one ear, they were present bilaterally in 100 per cent of cases.ConclusionMicro computed tomography imaging allowed three-dimensional assessment of the inner ear. Such assessments are important as they influence the surgical intervention and the evolution of future innovations.
Robust Bipedal Locomotion Based on a Hierarchical Control Structure

Published: March 2019

SummaryTo improve biped locomotion’s robustness to internal and external disturbances, this study proposes a hierarchical structure with three control levels. At the high level, a foothold sequence is generated so that the Center of Mass (CoM) trajectory tracks a planned path. The planning procedure is simplified by selecting the midpoint between two consecutive Center of Pressure (CoP) points as the feature point. At the middle level, a novel robust hybrid controller is devised to drive perturbed system states back to the nominal trajectory within finite cycles without chattering. The novelty lies in that the hybrid controller is not subject to linear CoM dynamic constraints. The hybrid controller consists of two sub-controllers: an oscillation controller and a smoothing controller. For the oscillation controller, the desired CoM height is specified as a sine-shaped function, avoiding a new attractive limit cycle. However, this controller results in the inevitable chattering because of discontinuities. A smoothing controller provides continuous properties and thus can inhibit the chattering problem, but has a smaller region of attraction compared with the oscillation controller. A hybrid controller merges the two controllers for a smooth transition. At the low level, the desired CoM motion is defined as tasks and embedded in a whole body operational space (WBOS) controller to compute the joint torques analytically. The novelty of the low-level controller lies in that within the WBOS framework, CoM motion is not subject to fixed CoM dynamics and thus can be generalized.

AbstractObjectivesPopulation-based colorectal cancer (CRC) screening programs that use a fecal immunochemical test (FIT) are often faced with a noncompliance issue and its subsequent waiting time (WT) for those FIT positives complying with confirmatory diagnosis. We aimed to identify factors associated with both of the correlated problems in the same model.MethodsA total of 294,469 subjects, either with positive FIT test results or having a family history, collected from 2004 to 2013 were enrolled for analysis. We applied a hurdle Poisson regression model to accommodate the hurdle of compliance and also its related WT for undergoing colonoscopy while assessing factors responsible for the mixture of the two outcomes.ResultsThe effect on compliance and WT varied with contextual factors, such as geographic areas, type of screening units, and level of urbanization. The hurdle score, representing the risk score in association with noncompliance, and the WT score, reflecting the rate of taking colonoscopy, were used to classify subjects into each of three groups representing the degree of compliance and the level of health awareness.ConclusionOur model was not only successfully applied to evaluating factors associated with the compliance and the WT distribution, but also developed into a useful assessment model for stratifying the risk and predicting whether and when screenees comply with the procedure of receiving confirmatory diagnosis given contextual factors and individual characteristics.
Does scientific effort reflect global need? A review of infectious disease publications over 100 years
Authors: Hayman D. T. S. , Baker M. G. 
Published: March 2019

AbstractIn a rational world, scientific effort would reflect society's needs. We tested this hypothesis using the area of infectious diseases, where the research response to emerging threats has obvious potential to save lives through informing interventions such as vaccination and prevention policies. Pathogens continue to evolve, emerge and re-emerge and infectious diseases that were once common become less so or their global distribution changes. A question remains as to whether scientific endeavours can adapt. Here, we identified papers on infectious diseases published in the four highest ranking, health-related journals over the 118 years from 1900. Focussing on outbreak-related and burden of disease-related metrics over the two time periods, 1990 to 2017 and 1900 to 2017, our analyses suggest that there is little underrepresentation of important infectious diseases among top ranked journals. Encouragingly our results suggest the scientific process is largely self-correcting.
