An Energy-Based Approach for n-d.o.f. Passive Dual-User Haptic Training Systems
Authors: Liu Fei , Licona Angel Ricardo , Lelevé Arnaud , Eberard Damien , Pham Minh Tu , Redarce Tanneguy 
Published: August 2019

SUMMARYThis paper introduces a dual-user training system whose design is based on an energetic approach. This kind of system is useful for supervised hands-on training where a trainer interacts with a trainee through two haptic devices, in order to practice on a manual task performed on a virtual or teleoperated robot (e.g., for an Minimally Invasive Surgery (MIS) task in a surgical context). This paper details the proof of stability of an Energy Shared Control (ESC) architecture we previously introduced for one degree of freedom (d.o.f.) devices. An extension to multiple degrees of freedom is proposed, along with an enhanced version of the Adaptive Authority Adjustment function. Experiments are carried out with 3 d.o.f. haptic devices in free motion as well as in contact contexts in order to show the relevance of this architecture.
BUILDING THE ENVIRONMENT AT PALENQUE: THE SACRED POOLS OF THE PICOTA GROUP
Authors: French Kirk D. , Straight Kirk D. , Hermitt Elijah J. 
Published: August 2019

AbstractThroughout the world, past and present, social organizations develop to cope with restricted water sources. Relying on traditional archaeology, labor estimates, and ethnographic data, the Palenque Pool Project set out to better understand a series of interconnected artificial water features located in the western sector of this Classic Maya site. Here, we detail our 2014–2015 fieldwork. First, there is consideration that the Picota Group was a civic-ceremonial center first established in the Early Classic period (a.d.250–500), one km to the west of the “downtown” nucleus of the site. A review of labor estimates for the construction of architectural features of the Picota Group follows. We then explore the ethnographic component, comparing similar pool configurations investigated in the highland Tzotzil community of Chamula in 2015. The article concludes with a theoretical discussion of how and why social organizations evolve to manage water resources in the region, with reference to ethnographic information from highland Tzotzil communities.
Feeling at home in lonely cities: an emotional history of the West German urban commune movement during the long 1970s
Authors: Häberlen Joachim C. 
Published: August 2019

AbstractIn the 1970s, a commune movement emerged in West German cities. The article explores this movement as an attempt to create spaces for feeling ‘at home’ in cities that many people perceived to be alienating. After providing a brief overview of the development of the commune movement, the article explores the new domesticity that emerged in communes. It first discusses the emotional and political ambitions that motivated mostly left-leaning students to move into communes, and then explores the practical attempts to create such spaces for feelings, how such attempts succeeded but also encountered many difficulties. The article thereby contributes to an understanding of what it takes for people to feel at home in cities.

Published: August 2019

AbstractObjectives:To examine the strengths and opportunities for improvement of current home care education practices to inform the development of the Home Care for Heart Health intervention, and to develop a web-based intervention for parents and clinicians with complimentary print materials that could provide the right education at the right time to foster a safer transition from hospital to home.Methods:An inter-professional focus group of parents, clinicians, and designers was formed to co-create a home care education intervention for parents of children with congenital heart disease (CHD) and their care team. We used the Integrated New Product Development process model created by Jonathon Cagan and Craig Vogel at Carnegie Mellon University to develop the intervention. This process model is a way of thinking that combines horizontal and inter-disciplinary teams, stakeholder-centric focus, and a system of qualitative discovery and development evolving towards quantitative methods of refinement.Results:Our team developed the Home Care for Heart Health intervention. The evidenced-based intervention includes a quick reference guide for parents of children with CHD, an accompanying app, family-friendly pathways, and clinician education.Conclusion:Using an inter-professional approach, our team of clinicians, parents, and design experts were able to co-create a clinician–parent home care education intervention with broad application and lifelong relevance to the Congenital Heart Disease Community.Practice Implications:Our intervention has the potential to be used as a model for other home care education interventions for parents of children with chronic illnesses.

Published: August 2019

AbstractWe report the case of a 10-year-old girl with Takayasu arteritis who developed acute onset wrist drop diagnosed with a large right axillary artery aneurysm compressing the surrounding structures. Our case is unique because it describes a rare presentation of Takayasu arteritis (axillary aneurysm) in a child that was treated successfully in an unconventional manner by transcutaneous embolisation following failure of trans-arterial approach.
Making Critical Thinking Skills Training Explicit, Engaging, and Effective through Live Debates on Current Political Issues: A Pilot Pedagogical Experiment
Authors: Tao Yu , Griffith Ed 
Published: August 2019

ABSTRACTWe piloted a pedagogical experiment to find out whether students can benefit from explicit demonstrations on critical thinking skills through live debates between two instructors on current political issues that are relevant to but not necessarily a specific part of the curriculum. The empirical results show that, through a series of interventions in the form of explicit demonstrations and debriefs on critical thinking skills in these issue-based live debates, students’ academic performance can significantly improve over a relatively short period of time. Training students’ critical skills through explicit, engaging pedagogy is not only economical in practical and pragmatic terms but also has significant and immediate short-term effects in a setting where there is a high proportion of first-generation undergraduate students of varying abilities and backgrounds.
Socio-economic and cultural disparities in diet among adolescents and young adults: a systematic review
Authors: Desbouys Lucille , Méjean Caroline , De Henauw Stefaan , Castetbon Katia 
Published: August 2019

AbstractObjective:To explore dietary differences according to socio-economic and sociocultural characteristics of adolescents and young adults.Design:A systematic review was conducted.Setting:The main search source was MEDLINE, consulted between January 2012 and March 2017. Quality of selected studies was assessed based on dietary measurement method, sample selection, socio-economic indicator choice and statistical modelling.Participants:Cross-sectional and longitudinal studies, assessing relationships between socio-economic status and dietary intake (patterns, scores and food groups) in the 10- to 40-year-old general population of high-income countries, were selected.Results:Among the 7250 reports identified, forty were selected, seventeen of which were of high quality; their conclusions, related only to adolescents, were combined and presented. The most favourable dietary patterns, higher dietary scores, greater consumption of fruits, vegetables and dairy products, and lower consumption of sugary sweetened beverages and energy-dense foods, were associated with better parental socio-economic status, particularly in terms of higher education. Migrant status was associated with plant-based patterns, greater consumption of fruits and vegetables and of sugary sweetened beverages and energy-dense foods. For the other food groups, and for young adults, very few high-quality studies were found.Conclusions:The socio-economic gradient in adolescent diets requires confirmation by higher-grade studies of a wider set of food groups and must be extended to young adult populations. Future nutritional interventions should involve the most vulnerable adolescent populations, taking account of socio-economic status and migration.
Cultural memory and identity in the context of war: Experiential, place-based and political concerns
Authors: Drozdzewski Danielle , Waterton Emma , Sumartojo Shanti 
Published: August 2019

AbstractRemembrance of war and conflict exposes the intricate interweaving of cultural memory and identity. Nations commemorate war to link narratives of the past with the present. This linking creates shared national narratives that temporally reinforce identities across the geography of the nation and among diverse citizenry. In this paper, the authors turn their attention towards the experiential and place-based concerns of the politics of memory within the context of war. It is argued that through attentiveness to individual experience we can better understand how cultural memory is enveloped into constructions of identity and critique such constructions alongside official narratives.

Published: August 2019

AbstractWe aimed to study the eating behavioral traits that associate with body mass index (BMI) among BMI-discordant twin pairs. This cross-sectional study examined self-reported eating behaviors in 134 healthy young adult twin pairs (57 monozygotic [MZ] and 77 same-sex dizygotic [DZ]), of whom 29 MZ and 46 DZ pairs were BMI discordant (BMI difference ≥ 3 kg/m2). In both MZ and DZ BMI-discordant pairs, the heavier co-twins reported being less capable of regulating their food intake optimally than their leaner co-twins, mainly due to ‘frequent overeating’. Furthermore, the heavier co-twins reported augmented ‘disinhibited eating’, ‘binge-eating scores’ and ‘body dissatisfaction’. The twins agreed more frequently that the heavier co-twins (rather than the leaner co-twins) ate more food in general, and more fatty food, in particular. No significant behavioral differences emerged in BMI-concordant twin pairs. Overeating — measured by ‘frequent overeating’, ‘disinhibited eating’ and ‘binge-eating score’ — was the main behavioral trait associated with higher BMI, independent of genotype and shared environment.
The Michigan State University Twin Registry (MSUTR): 15 Years of Twin and Family Research

Published: August 2019

AbstractThe primary aim of the Michigan State University Twin Registry (MSUTR) is to examine developmental differences in genetic, environmental, neural, epigenetic, and neurobiological influences on psychopathology and resilience, particularly during childhood and adolescence. The MSUTR has two broad components: a large-scale, population-based registry of child, adolescent, and adult twins and their families (current N ~30,000) and a series of more focused and in-depth studies drawn from the registry (projected N ~7200). Participants in the population-based registry complete a family health and demographic questionnaire via mail. Families can then be recruited for one or more of the intensive, in-person studies from the population-based registry, using any one of several recruitment strategies (e.g., population-based, based on their answers to the registry questionnaire). These latter studies target a variety of biological, genetic, and environmental phenotypes, including multi-informant measures of psychiatric and behavioral phenotypes, functional and structural neuroimaging, comprehensive measures of the twin family environment (e.g., census and neighborhood informant reports of twin neighborhood characteristics, videotaped interactions of child twin families), buccal swab and salivary DNA samples, and/or assays of adolescent and adult steroid hormone levels. This article provides an overview of the MSUTR and describes current and future research directions.
Middle‐Atmosphere Dynamics Observed With a Portable Muon Detector

Published: August 2019

AbstractIn the past years, large particle physics experiments have shown that muon rate variations detected in underground laboratories are sensitive to regional, middle‐atmosphere temperature variations. Potential applications include tracking short‐term atmosphere dynamics, such as Sudden Stratospheric Warmings. We report here that such sensitivity is not only limited to large surface detectors under high‐opacity conditions. We use a portable muon detector conceived for muon tomography for geophysical applications, and we study muon rate variations observed over 1 year of measurements at the Mont Terri Underground Rock Laboratory, Switzerland (opacity of ~700 meter water equivalent). We observe a direct correlation between middle‐atmosphere seasonal temperature variations and muon rate. Muon rate variations are also sensitive to the abnormal atmosphere heating in January–February 2017, associated to a Sudden Stratospheric Warming. Estimates of the effective temperature coefficient for our particular case agree with theoretical models and with those calculated from large neutrino experiments under comparable conditions. Thus, portable muon detectors may be useful to (1) study seasonal and short‐term middle‐atmosphere dynamics, especially in locations where data are lacking such as midlatitudes, and (2) improve the calibration of the effective temperature coefficient for different opacity conditions. Furthermore, we highlight the importance of assessing the impact of temperature on muon rate variations when considering geophysical applications. Depending on latitude and opacity conditions, this effect may be large enough to hide subsurface density variations due to changes in groundwater content and should therefore be removed from the time series.
Rainfall Estimation From Ground Radar and TRMM Precipitation Radar Using Hybrid Deep Neural Networks

Published: August 2019

AbstractRemote sensing of precipitation is critical for regional, continental, and global water and climate research. This study develops a deep learning mechanism to link between point‐wise rain gauge measurements, ground‐based, and spaceborne radar reflectivity observations. Two neural network models are designed to construct a hybrid rainfall system, where the ground radar is used to bridge the scale gaps between rain gauge and satellite. The first model is trained for ground radar using rain gauge data as target labels, whereas the second model is for spaceborne Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR) using ground radar estimates as training labels. Data from 1 year of observations in Florida during 2009 are utilized to illustrate the application of this hybrid rainfall system. Validation using independent data in 2009, as well as 2‐year comparison against the standard PR products, demonstrates the promising performance and generality of this innovative rainfall algorithm.
Surface Rupture and Distributed Deformation Revealed by Optical Satellite Imagery: The Intraplate 2016 Mw6.0 Petermann Ranges Earthquake, Australia

Published: August 2019

AbstractHigh‐resolution optical satellite imagery is used to quantify vertical surface deformation associated with the intraplate 20 May 2016 Mw6.0 Petermann Ranges earthquake, Northern Territory, Australia. The 21 ± 1‐km‐long NW trending rupture resulted from reverse motion on a northeast dipping fault. Vertical surface offsets of up to 0.7 ± 0.1m distributed across a 0.5‐to‐1‐km‐wide deformation zone are measured using the Iterative Closest Point algorithm to compare preearthquake and postearthquake digital elevation models derived from WorldView imagery. The results are validated by comparison with field‐based observations and interferometric synthetic aperture radar. The pattern of surface uplift is consistent with distributed shear above the propagating tip of a reverse fault, leading to both an emergent fault and folding proximal to the rupture. This study demonstrates the potential for quantifying modest (<1 m) vertical deformation on a reverse fault using optical satellite imagery.
Deep Crustal Faults, Shear Zones, and Magmatism in the Eastern Cordillera of Colombia: Growth of a Plateau From Teleseismic Receiver Function and Geochemical Mio‐Pliocene Volcanism Constraints

Published: August 2019

AbstractThe Eastern Cordillera of Colombia, in the northern Andes, is an example of an orogen in which Mesozoic basins were compressed during the Cenozoic, forming a ~2,500‐m‐high plateau in its northern portion. Significant shortening and crustal thickening have contributed to the construction of the present topography and elevation. In this contribution, we combine the use of teleseismic receiver functions, Hf isotopes, whole‐rock geochemistry, and U‐Pb dating to help elucidate the main mechanisms that played a role in the crustal thickening and uplift of the cordillera. Receiver functions calculated for three stations on top of the plateau are consistent with the presence of thrusts that converge into major crustal interfaces at upper‐middle crustal depths; they also suggest the existence of two crustal anisotropic layers beneath the western flank of the cordillera, which we interpret to have formed as a result of shearing. In the northern portion of the plateau, in the area where two Mio‐Pliocene volcanic domes and their related deposits outcrop, a lower crustal high seismic velocity layer is suggested by the receiver functions; we propose magmatic underplating for the origin of this layer. The geochemical characteristics of the volcanic rocks in the area are consistent with partial melt in a mantle influenced by slab‐related fluids; this magma could have been added to the crust and portions of it ascended and reached the surface, experiencing assimilation and differentiation during the process. We hypothesize that this Mio‐Pliocene volcanism was related to flattening of the Nazca subducting slab.
Cross‐Isobath Freshwater Exchange Within the North Atlantic Subpolar Gyre
Authors: Pennelly Clark , Hu Xianmin , Myers Paul G. 
Published: August 2019

AbstractThe amount of cross‐isobath freshwater exchange within the North Atlantic subpolar gyre is estimated from numerical modelling simulations. A regional configuration of the Nucleus for European Modelling of the Ocean model is used to carry out three simulations with horizontal resolutions of 1/4°, 1/12°, and 1/4° with a 1/12° nested domain. Freshwater transport is calculated across five isobaths in six regions for three distinct water masses. Fresh Polar Water is only transported offshore from the western coast of Greenland and the southern coast of Labrador; other regions have onshore transport of freshwater or little offshore transport. The salty water masses of Irminger and Labrador Sea Water typically have onshore transport, acting to promote subsurface freshening of the Labrador Sea. The freshwater transport via the Polar Water mass experiences a large degree of seasonal variability, while the Irminger and Labrador Sea Water masses do not. Decomposing the freshwater transport into the mean and turbulent components indicates that most regions and water masses have stronger freshwater transport associated with the mean flow while the turbulent flow in often the opposite direction. The only water mass and region where the mean and turbulent freshwater transport act in the same direction is Polar Water along the western margin of Greenland. Model resolution plays an important role in determining cross‐isobath exchange as our results from an identically forced simulation at 1/4° has reduced seasonal cycles, reduced transport, and sometimes transport in the opposite direction when compared against the 1/12° resolution simulations.
Velocities of Positive Leaders in Intracloud and Negative Cloud‐to‐Ground Lightning Flashes

Published: August 2019

AbstractWe have performed a statistical study on velocities of positive leaders in 553 intracloud (IC) and 220 negative cloud‐to‐ground (−CG) flashes. It is found that velocities of positive leaders in IC and −CG flashes have very similar distributions, with the vast majority in the range of 1 to 3 × 104 m/s. Average velocities are 1.64 and 1.55 × 104 m/s, respectively, for positive leaders in IC and −CG flashes. Velocities of positive leaders in IC flashes show a clear negative correlation with initiation altitudes and leader propagation altitudes, similar to negative leaders in IC flashes. The negative correlation also exists for positive leaders in −CG flashes but is relatively weak. We also found that positive leaders in both IC and −CG flashes propagate with a stable velocity, contrary to downward positive leaders in +CG flashes and upward positive leaders in negative upward and triggered flashes, which were usually found to accelerate during propagations. These results suggest that positive leaders in IC and −CG flashes and those in +CG, upward and triggered flashes propagate with essentially different velocities. The differences and possible reasons are discussed.
Impact of GNSS Signal Delay Assimilation on Short Range Weather Forecasts Over the Indian Region

Published: August 2019

AbstractRadio signals transmitted from a satellite constellation and gathered by a ground‐based Global Navigation Satellite System (GNSS) receiver allow computation of zenith tropospheric delay (ZTD), which is related to the atmospheric moisture. This study investigates the impact of assimilating ZTD obtained from a ground‐based GNSS network on a numerical weather prediction model analyses and subsequent forecasts quality. The numerical data assimilation experiments are performed using three‐dimensional variational data assimilation system in the Weather Research and Forecasting model, at 10‐km horizontal grid spacing for the entire month of July 2017. A comparison with European Centre for Medium‐Range Weather Forecast analyses shows a clear positive impact of ZTD assimilation on the lower to middle tropospheric moisture, upper air temperature, and middle and upper tropospheric wind; errors are reduced by as large as 4%, when compared to the model run without ZTD assimilation. The impact on the analyses and forecast quality of surface meteorological variables is mostly neutral with some indication of positive impact on surface pressure. An improvement in the rainfall forecasts is also noticed when model assimilates ZTD observations. In addition, the impact of the formulation of forward model, which calculates model equivalent of the GNSS ZTD, has been assessed on ZTD assimilation. A revised forward model has been implemented within the Weather Research and Forecasting assimilation system. The revised forward model outperforms the original model for ZTD assimilation. Overall result implies that GNSS ZTD data has a good potential for improving the weather prediction and advocates the strengthening of the ground‐based GNSS network over the Indian region, which is currently very sparse.
