Enabling robust and accurate navigation for UAVs using real-time GNSS precise point positioning and IMU integration
Authors: Chi C. , Zhan X. , Wang S. , Zhai Y. 
Published: October 2020

ABSTRACTAccurate navigation is required in many Unmanned Aerial Vehicle (UAV) applications. In recent years, GNSS Precise Point Positioning (PPP) has been recognised as an efficient approach for providing precise positioning services. In contrast to the widely used Real-Time Kinematic (RTK), PPP is independent of reference stations, which greatly broadens its scope of application. However, the accuracy and reliability of PPP can be significantly decreased by poor GNSS satellite geometry and outage. In response, a real-time four-constellation GNSS PPP is applied to improve the geometry in this work, and PPP is tightly coupled with an Inertial Measurement Unit (IMU) to smooth the position and velocity output, thus improving the robustness of the navigation solution. Experimental flight tests are carried out using a UAV in an open-sky area, and GNSS-challenged environments are simulated. The results show that the four-constellation GNSS PPP/IMU integration reduces the Root-Mean-Square (RMS) Three-Dimensional (3D) positioning and velocity error by 76.4% and 67.1%, respectively, in open sky with respect to the one-GNSS PPP. Under scenarios where GNSS measurements are insufficient, the coupled system can still provide continuous solutions. Moreover, the coupled PPP/IMU system can also maintain the convergence of PPP during GNSS-challenged periods and can greatly shorten the re-convergence period of PPP when the UAV returns to the open sky.

Abstract

Introduction:
Food insecurity (FI) is the lack of consistent access to enough food for an active and healthy life. Community-based hunger relief programs often serve as emergency food sources for families with FI. However, these programs may not provide foods that diverse populations of people prefer. We sought to evaluate the dietary patterns and preferences of families living in food-insecure neighborhoods and utilizing a community-based hunger relief program, in order to improve the utilization of local nutritional programs.

Methods:
We examined the Help Our People Eat (HOPE) community-based mobile meal program. Free-listing interviews (n = 63) were conducted with English-(66%) and Spanish-speaking (34%) participants of the program. Participants were asked about FI risk, food preferences, and dietary behaviors at home.

Results:
The majority of participants (90%) had children in the household. About 60% reported not being able to afford the type of food they enjoyed. Most participants reported using stoves for cooking (80%). Participants overwhelmingly cooked with chicken, beef, and pork. The most common side dishes included potatoes, rice, and salad. Most participants reported no interest in cooking differently or learning new recipes.

Conclusions:
A common theme throughout interviews was that families prefer similar meals, but may prepare them differently based on the language spoken. Food preferences consisted of a high intake of carbohydrate-rich meals, perhaps because these foods may be cheaper and easier to access. Notably, new recipes and cooking methods were not a priority for these families, possibly due to the time and effort needed to learn them.

Abstract

Introduction:
Access to patient medical data is critical to building a real-time data analytic pipeline for improving care providers’ ability to detect, diagnose, and prognosticate diseases. Critical congenital heart disease (CCHD) is a common group of neonatal life-threatening defects that must be promptly diagnosed to minimize morbidity and mortality. CCHD can be diagnosed both prenatally and postnatally. However, despite current screening practices involving oxygen saturation analysis, timely diagnosis is missed in approximately 900 infants with CCHD annually in the USA and can benefit from increased data processing capabilities. Adding non-invasive perfusion measurements to oxygen saturation data can improve the timeliness and fidelity of CCHD diagnostics. However, real-time monitoring and interpretation of non-invasive perfusion data are currently limited.

Methods:
To address this challenge, we created a hardware and software architecture utilizing a Pi-top™ for collecting, visualizing, and storing dual oxygen saturation, perfusion indices, and photoplethysmography data. Data aggregation in our system is automated and all data files are coded with unique study identifiers to facilitate research purposes.

Results:
Using this system, we have collected data from 190 neonates, 130 presumably without and 60 with congenital heart disease, in total comprising 1665 min of information. From these data, we are able to extract non-invasive perfusion features such as perfusion index, radiofemoral delay, and slope of systolic rise or diastolic fall.

Conclusion:
This data collection and waveform analysis is relatively inexpensive and can be used to enhance future CCHD screening algorithms.
Socio-Legal Studies in Germany and the UK: Theory and Methods
Authors: Hendry Jennifer , Creutzfeldt Naomi , Boulanger Christian 
Published: October 2020

AbstractThis Special Issue considers the situated and contextualized development of socio-legal, or law and society, scholarship within two materially different legal and academic cultures, namely Germany and the United Kingdom, with a view to achieving a better understanding of why and how such differences in understanding and practice have arisen. The contributions are grouped into three themes. The first reflects upon the influence of institutional contexts and scholarly traditions in terms of the development of those approaches that come under the banner of socio-legal studies. The second features contributions that adopt a comparative perspective in terms of selected areas of law, pointing to notably different approaches taken in Germany and the UK, and considering the development of these respective situations. The third looks at the key contemporary trends, theoretical applications, and methodological approaches taken within both countries’ socio-legal academic contexts.
Comparative Genealogies of “Contract and Society”
Authors: Eller Klaas Hendrik 
Published: October 2020

AbstractSince contracts form a basic institution of every legal order, the interdisciplinary orientation of concepts of contracts reveals socio-legal inclinations of a legal order more broadly. Contrasting the UK and US Common Law of contracts with developments under German law, this Article examines the relation between normative and social science approaches, notably rooted in economics, economic sociology, and social theory in the genealogy of contract law. A shared leitmotif over the 20th century has been the drive to account for the societal embeddedness of contract. However, conceptualizations of “Contract and Society” differ considerably between legal orders in their disciplinary ingredients and design. In the US, and to a lesser extent also in the UK, the rather continuous reception of legal realism has paved the way for broad interdisciplinary perspectives on contract law, ranging from classical socio-legal, empirical work (e.g., Macaulay), economics (e.g., Williamson), sociology (e.g., Powell), and critical theory (e.g., Kennedy) to today’s landscape, where essentially instrumental and ideal-normative theories compete. Alternatively, in Germany, where the realist heritage was more ephemeral, the transformations of contract law were processed from within legal discourse and foremost in their effects on private autonomy as conceptualized, for example, in German idealism, discourse theory and critical theory. Similarly, the “constitutionalization” of contract law—even if championed for fostering private law’s reflexivity—has, for the most part, defied a socio-legal orientation. Finally, the Article highlights the path dependencies with which these different starting points translate in current debates around the role of contract in transnational governance.
Gender in Socio-Legal Teaching and Research in Germany
Authors: Schultz Ulrike 
Published: October 2020

AbstractGender in socio-legal teaching and research in Germany is a story of impediments, hindrances, and of singleperson initiatives—my personal history being a part of this. But it is also a story of influences upon the impulse and inspiration to undertake socio-legal work. My Article is therefore influenced by (feminist) standpoint theory (Harding 1991). Germany has had a very conservative family culture and, over the past decades, many of the legal regulations that infringed upon women have had to be adapted, in what was quite a tedious political process, to comply with the German Constitution’s gender equality clause. Only in the past decade has gender awareness in law faculties increased and gained acceptance, usually as a result of greater focus on diversity issues, and anti-discrimination legislation. Obstacles have resulted from a lack of cooperation between the actors in social sciences and law, as well as in academia and gender equality practice, and a lack of understanding between more conservative and more progressive women. Socio-legal research was, and is, needed to deliver empirical evidence and provide theoretical foundations for cultural and legal changes as societies progress towards gender equality. Socio-legal teaching is needed to alert lawyers to necessary change, to enable them to undertake informed critique, and to prepare them to act. There are, however, marked deficits in socio-legal teaching and research on gender. In spite of an increased political acceptance, gender equality is still mainly a women’s project.
Diversity and systematics of Middle-Late Ordovician calcified cyanobacteria and associated microfossils from Ordos Basin, North China

Published: October 2020

AbstractCalcified cyanobacteria are of considerable research value for reconstructing the ecology of Paleozoic and Mesozoic benthic communities on carbonate platforms due to their ability to produce oxygen and fix nitrogen and CO2. The diversity and abundance of calcified cyanobacteria was initially suggested to have declined in the Middle and Late Ordovician, although more recent work suggests that complex and diverse assemblages persisted throughout the Ordovician. Here, calcified cyanobacteria and associated microfossil flora from the Middle and Late Ordovician of the Ordos Basin, North China Block, are systematically described for the first time based on 1330 thin sections from seven outcrop profiles and four drill cores. In total, there are 18 species belonging to 16 genera, including a new species,Proaulopora ordosian. sp.Girvanella,Subtifloria,Acuasiphonoria,Xianella, and Oscillatoriaceae gen. indet. are assigned to Osillatoriales of cyanobacteria;Ortonella,Hedstroemia,Cayeuxia,Zonotrichites,Proaulopora, andPhacelophytonare assigned to Nostocales of cyanobacteria; andGarwoodia,Renalcis,Izhella,Rothpletzella, andWetheredellaare assigned to calcified Microproblematica. A literature survey of Ordovician microfloral assemblages shows that cyanobacteria and associated microfossils occur in reef, open platform, lagoon, and tidal facies. Most genera occur on at least two independent blocks, and many have a cosmopolitan distribution in similar sedimentary facies. Our research suggests that calcified cyanobacteria and associated microfossils formed complex ecosystems and played greater ecological roles on carbonate platforms during the late Middle and Late Ordovician than was previously thought.UUID:http://zoobank.org/1812ccf8-136c-4cff-92ba-faeaf06523ef
Sensitivity analysis for network observations with applications to inferences of social influence effects
Authors: Xu Ran , Frank Kenneth A. 
Published: October 2020

AbstractThe validity of network observations is sometimes of concern in empirical studies, since observed networks are prone to error and may not represent the population of interest. This lack of validity is not just a result of random measurement error, but often due to systematic bias that can lead to the misinterpretation of actors’ preferences of network selections. These issues in network observations could bias the estimation of common network models (such as those pertaining to influence and selection) and lead to erroneous statistical inferences. In this study, we proposed a simulation-based sensitivity analysis method that can evaluate the robustness of inferences made in social network analysis to six forms of selection mechanisms that can cause biases in network observations—random, homophily, anti-homophily, transitivity, reciprocity, and preferential attachment. We then applied this sensitivity analysis to test the robustness of inferences for social influence effects, and we derived two sets of analytical solutions that can account for biases in network observations due to random, homophily, and anti-homophily selection.
Reconciling the Theoretical and Empirical Study of International Norms: A New Approach to Measurement
Authors: GIRARD TYLER 
Published: October 2020

AbstractDespite extensive research on international norms, our approach to measurement has not kept pace with theoretical advancements. Existing research often relies on single indicators to facilitate cross-national analysis or employs case-study designs that provide greater nuance but restricted scope. Given these limitations, this note argues that item-response theory (IRT) provides a framework for strengthening the link between our theoretical understanding of norms and empirical measurement of norm adoption. In turn, I develop a modified Bayesian model with substantively informed dynamic priors. The proposed approach is evaluated with the lesbian, gay, and bisexual (LGB) equality norm, using 13 policies and laws across 196 countries (1990–2017). The results are broadly consistent with theoretical expectations while also providing new empirical evidence on the evolution of the norm across space and time. This note highlights the significant potential in greater interaction between both latent measurement approaches and scholarship on international norms.

Published: October 2020

AbstractVisceral leishmaniosis is one of the most important zoonotic diseases on the planet and dogs are the main reservoir of canine visceral leishmaniosis (CVL) in endemic areas. They play an important role in human infection because in dogs the disease appears long time after infection, and they can move uncontrollably, contributing to disperse the parasite. To take the decision to treat the animals or for euthanasia, in an elimination programme, in order to reduce the parasitic load, it is necessary to diagnose correctly, having more effective tools. Our group has developed a new recombinant antigen-based kinesin-related gene of Leishmania braziliensis (Lbk39), which shows 59% amino acid identity to the L. infantum homologue. The Lbk39 gene was synthesized, inserted into the pLEXSY-sat2 vector and transfected into L. tarentolae cells by electroporation. The recombinant protein was secreted in the culture with a C-terminal histidine marker, purified, generating a product at 337.68 μg mL−1. A total of 152 sera from dog's endemic and non-endemic areas were used, being 78 positives and 75 negatives. The antigen Lbk39 showed 100% sensitivity and 96.1% specificity. We compared this antigen with other antigens such as total extract of the parasite, TRDPP, and our data indicate that Lbk39 has potential application in the diagnosis of CVL through antibody detection.

Published: October 2020

AbstractBackgroundVirtual reality exposure therapy (VRET) is currently being used to treat social anxiety disorder (SAD); however, VRET's magnitude of efficacy, duration of efficacy, and impact on treatment discontinuation are still unclear.MethodsWe conducted a meta-analysis of studies that investigated the efficacy of VRET for SAD. The search strategy and analysis method are registered at PROSPERO (#CRD42019121097). Inclusion criteria were: (1) studies that targeted patients with SAD or related phobias; (2) studies where VRET was conducted for at least three sessions; (3) studies that included at least 10 participants. The primary outcome was social anxiety evaluation score change. Hedges' g and its 95% confidence intervals were calculated using random-effect models. The secondary outcome was the risk ratio for treatment discontinuation.ResultsTwenty-two studies (n = 703) met the inclusion criteria and were analyzed. The efficacy of VRET for SAD was significant and continued over a long-term follow-up period: Hedges' g for effect size at post-intervention, −0.86 (−1.04 to −0.68); three months post-intervention, −1.03 (−1.35 to −0.72); 6 months post-intervention, −1.14 (−1.39 to −0.89); and 12 months post-intervention, −0.74 (−1.05 to −0.43). When compared to in vivo exposure, the efficacy of VRET was similar at post-intervention but became inferior at later follow-up points. Participant dropout rates showed no significant difference compared to in vivo exposure.ConclusionVRET is an acceptable treatment for SAD patients that has significant, long-lasting efficacy, although it is possible that during long-term follow-up, VRET efficacy lessens as compared to in vivo exposure.
Health and health-care utilisation in old age: the case of older men living alone

Published: October 2020

AbstractA growing number of older men are living alone. They are often referred to as an at-risk group in health-care systems. The purpose of this article is to establish an overview of these men's health and health-care utilisation. We do so by drawing on three sources: an online survey with health-care professionals, data from a national self-report health study and register-based data on health-care utilisation. The results show that older men living alone generally have lower health scores than older men co-habiting and that, among older men living alone, lower educational level is associated with lower health scores but also a greater use of free-of-charge health-care services. Health-care professionals conducting preventive home visits consider older men's social needs the most pronounced problem for the men's wellbeing and call for new services to be custom made for them. In this article, we discuss differences between older men living in rural and urban areas and between those who are single, divorced or widowed. We conclude that health and social care systems must differentiate between sub-groups of older men living alone when developing new services and that free-of-charge services, such as general practitioners and home care, should be considered as vehicles for addressing health inequities.

AbstractSocial cognitive deficits can have many negative consequences, spanning social withdrawal to psychopathology. Prior work has shown that child maltreatment may associate with poorer social cognitive skills in later life. However, no studies have examined this association from early childhood into adolescence. Using data from the Avon Longitudinal Study of Parents and Children (ALSPAC; n = 4,438), we examined the association between maltreatment (caregiver physical or emotional abuse; sexual or physical abuse), assessed repeatedly (every 1–3 years) from birth to age 9, and social cognitive skills at ages 7.5, 10.5, and 14 years. We evaluated the role of both the developmental timing (defined by age at exposure) and accumulation of maltreatment (defined as the number of occasions exposed) using a least angle regression variable selection procedure, followed by structural equation modeling. Among females, accumulation of maltreatment explained the most variation in social cognitive skills. For males, no significant associations were found. These findings underscore the importance of early intervention to minimize the accumulation of maltreatment and showcase the importance of prospective studies to understand the development of social cognition over time.

Published: October 2020

AbstractAnomalous origin of the left coronary artery from the pulmonary artery causes heart failure and death in infancy. In rare adult survivors with well-developed collaterals, surgical left coronary ligation to arrest steal is often combined with bypass grafting. Transcatheter left coronary artery closure in a symptomatic adult as an alternative to surgical ligation resulted in complete resolution of inducible ischaemia on myocardial perfusion imaging.

AbstractBackground:Small-cell lung cancer (SCLC) has poor prognosis owing to the high risk of distant metastasis.Purpose:To identify the prognosticators of brain metastasis from SCLC treated by whole-brain radiotherapy.Material and methods:We evaluated patients diagnosed with primary brain metastasis from SCLC between 1 January 2010 and 30 September 2019. Age, sex, disease stage at the first examination, time to the diagnosis of brain metastasis, state of other lesions at the diagnosis of brain metastasis, haematological parameters, neurologic symptoms, whole-brain radiotherapy dose, imaging findings of the brain metastasis (single or multiple), and chemotherapy and radiotherapy status were investigated for correlations with survival from the diagnosis of brain metastasis.Results:A total of 24 participants were evaluated. After radiotherapy, the median survival period was 118·5 (22–998) days, and 21 patients died during the follow-up period. Multivariate stepwise analysis of the four parameters of lactate dehydrogenase (LDH) level (within vs. above the reference value), platelet level (continuous variable), neurologic symptoms (with versus. without), and NSE (neuron-specific enolase) level (continuous variable) identified the following significant differences: neurologic symptoms were 3·81 (95% CI 1·07–13·5, p = 0·04), and NSE was 1·01 (95% CI 1·00–1·01, p = 0·04).Conclusion:NSE and neurologic symptoms are prognosticators of brain metastasis from SCLC treated by whole-brain radiotherapy.
