Orbit deployment and drag control strategy for formation flight while minimizing collision probability and drift
Authors: Yoon Zizung , Lim Yeerang , Grau Sebastian , Frese Walter , Garcia Manuel A. 
Published: March 2020

AbstractThe compact form factor of nanosatellites or even smaller satellites makes them predestined for distributed systems such as formations, constellations or large swarms. However, when it comes to orbit insertion of multiple satellites, these ride share payloads have constrains in the deployment parameters such as sequence, direction, velocity and time interval. Especially for formation flight missions without propulsion, where the satellites should minimize their relative distance drift either passively or by atmospheric drag control, the initial ejection parameters must find a proper trade-off between collision probability and relative drift. Hence, this article covers short-term (first orbit) collision analysis, long-term (30 days) drift analysis and atmospheric drag control strategy for long-term distance control of multiple satellites. The collision analysis considers various orbit deployment parameters such as insertion direction and tolerance, orbital elements of insertion and time span. To cover the parameter space, a Monte Carlo simulation was conducted to identify the impact of these parameters. It showed that for collision probability the major factor is the time span between two ejections and the precision of the deployment vector. For long-term drift analysis, orbit perturbation such as atmosphere andJ2 terms are considered. The result showed that for drift minimizing, minimizing the along-track variation is more substantial than reducing the time span between ejections. Additionally, a drag control strategy to reduce the relative drift of the satellites is described. The results have been applied on the S-NET mission, which consists of four nanosatellites with the task to keep their relative distance within 400 km to perform intersatellite communication experiments. The flight results for orbital drift show equal or better performance (0.1–0.7 km/day) compared to the worst-case simulation scenario, implying that orbit perturbation was chosen correctly and all orbit injection tolerances were within specified range. The drag control maneuver showed good matching to the flight results as well with a deviation for the maneuver time of approximately 10%.

Abstract
Objectives
Mindfulness-based cognitive therapy (MBCT) is an evidence-based treatment to prevent relapse in individuals with recurrent major depressive disorder (MDD). It is not clear if MBCT is an effective therapy for current depression, and it is not clear what mechanisms are responsible for the effectiveness of MBCT. Theoretically, MBCT is believed to modify the processing of emotional information and reduce cognitive vulnerability to depression; however, it is not clear if MBCT leads to normalization of attentional biases in depressed individuals. The aim of the current study was to determine if MBCT can modify some of the attentional biases underlying depression in MDD.

Methods
Participants were 53 individuals with diagnosis of current MDD. They were randomly assigned to either MBCT (n = 25) or wait list control group (n = 28) condition. Before and after the 8-week MBCT intervention participants completed the Center for Epidemiological Studies Depression scale (CESD), they viewed slides presenting sad, angry, happy, and neutral facial expressions, and their eye movements were recorded during the viewing task.

Results
As expected, compared to participants in the control group, the CESD scores of participants who received MBCT decreased following treatment, their attention to sad faces decreased, and their attention to happy faces increased. Moreover, cross-lagged analysis suggested a causal link from changes in attentional bias to changes in depression.

Conclusions
We found that MBCT can modify the attentional processing of emotional facial stimuli and that attentional bias modification may translate into clinical improvement in currently depressed individuals.
An experimental investigation into enhancing oil recovery using combination of new green surfactant with smart water in oil-wet carbonate reservoir
Authors: Mosalman Haghighi Omid , Mohsenatabar Firozjaii Ali 
Published: March 2020

AbstractEnhancing oil recovery from oil-wet carbonate oil reservoir is an important challenge in the world, especially in Middle East oil field. Surfactant and smart water can change the interfacial tension and wettability condition of this type of rock to water wet from oil wet. The present study follows the experimental work of the combination of new green surfactant with smart water to enhance oil recovery from a carbonate oil-wet rock. Wettability alternation and IFT reduction by surfactant, smart water and combination of surfactant with smart water were investigated experimentally. The results show that making surfactant solution using smart water can reduce oil saturation by reducing IFT and alter wettability conditions. The oil recovery factor at the end of water, surfactant and surfactant–smart water flooding was 36, 52 and 66%, respectively. It shows that combination of surfactant with smart water can help surfactant to be powerful.
Growth parameters and resistance to Sphaerulina musiva-induced canker are more important than wood density for increasing genetic gain from selection of Populus spp. hybrids for northern climates
Authors: Niemczyk Marzena , Thomas Barb R. 
Published: March 2020

Abstract
Key message
New genotypes of hybrid poplars from theAigeirosandTacamahacasections have great potential for increasing genetic gain from selection. The most promising traits are associated with productivity and resistance toSphaerulina musiva-induced canker while wood density can be selected for secondarily. A minimum age of 8 years is reliable to select fast-growing resistant clones in northern climates.

Context
Productivity, wood density, and disease resistance of hybrid poplar clones are important traits when selecting for cultivation at an industrial scale.

Aims
We studied 1978 hybrid poplar clones from 63 families, bred from poplars native (Populus balsamifera and Populus deltoides) and non-native to Canada from the Aigeiros and Tacamahaca sections, to improve economically important traits for plantations in northern Alberta.

Methods
Genetic parameters for diameter at breast height (DBH), height, resistance to Sphaerulina musiva-induced canker, and wood density were determined up to age 10.

Results
A mean annual increment of 16.5 m3 ha−1 year−1 was achieved at age 10 in the best-performing clones. The potential genetic gain for DBH, height, and canker resistance, 37%, 26%, and ~ 13%, respectively, was achieved when selecting the top 10% of the tested clones. The genetic effect for wood density was weak. The age-age genetic correlations identified age eight as a reliable selection age.

Conclusion
The new hybrid poplar clones tested exhibited great potential for tree improvement. The next phase of selection should test a reduced number of clones on different site types, identifying stable clones for productivity and resistance, while wood density can be selected for secondarily. In northern regions, a minimum age of 8 years is reliable to select fast-growing resistant clones for commercial deployment.
Controversies on Public Religious Pedagogy: religious education in times of post-democratic populism, global warming and economization of education
Authors: Herbst Jan-Hendrik 
Published: March 2020

AbstractIn times of social crises, Public Religious Pedagogy is emerging as “a new paradigm in the field of Religious Pedagogy” (Manfred L. Pirner). This paper aims to strengthen this approach through a critical review. To achieve this, the theoretical foundations of Public Religious Pedagogy will be examined more closely in order to investigate their strengths and weaknesses. The result of these considerations is to expand historical sources and interdisciplinary references of Public Religious Pedagogy: It is necessary to interpret the concept more broadly. Finally, this article argues in favour of acriticalandpropheticPublic Religious Pedagogy.
On modeling blockchain-enabled economic networks as stochastic dynamical systems
Authors: Zhang Zixuan , Zargham Michael , Preciado Victor M. 
Published: March 2020

AbstractBlockchain networks have attracted tremendous attention for creating cryptocurrencies and decentralized economies built on peer-to-peer protocols. However, the complex nature of the dynamics and feedback mechanisms within these economic networks has rendered it difficult to reason about the growth and evolution of these networks. Hence, proper mathematical frameworks to model and analyze the behavior of blockchain-enabled networks are essential. To address this need, we establish a formal mathematical framework, based on dynamical systems, to model the core concepts in blockchain-enabled economies. Drawing on concepts from differential games, control engineering, and stochastic dynamical systems, this paper proposes a methodology to model, simulate, and engineer networked token economies. To illustrate our framework, a model of a generalized token economy is developed, where miners provide a commodity service to a platform in exchange for a cryptocurrency and users consume a service from the platform. We illustrate the dynamics of token economies by simulating and testing two different block reward strategies. We then conclude by outlining future research directions that will integrate additional methods from signal processing and control theory into the toolkit for designers of blockchain-enabled economic systems.
Idiopathic congenital anomalous bands
Authors: Kerkeni Yosra , Aicha Bouden , Hamzaoui Mourad 
Published: March 2020

Background and Objectives: Purpose:
There are various causes and associated conditions in anomalous bands. Idiopathic congenital anomalous bands are extremely rare. The use of the term “congenital bands” may, in reality, not describe the same situation. The study aims to report our series of idiopathic anomalous bands and proposes an accurate and consistent classification of anomalous bands in order to clarify the origin of each band.

Methods:
This study, conducted from January 2005 to January 2018, included all patients admitted to the emergency departments with a clinical diagnosis of intestinal obstruction resulting from bands that have no identifiable embryological or acquired basis called “idiopathic”. Recorded operative findings included the site of obstruction and the operative procedure to relieve it.

Results:
The sample consists of seven boys and three girls with age range from one day to 9 years with symptoms and signs indicative of intestinal obstruction. Surgical intervention was performed, and intraoperative findings revealed a thick and vascularized idiopathic band, in different locations, which was responsible for intestinal obstruction in all patients. Clinical courses were uneventful in eight cases.

Conclusion:
Idiopathic anomalous congenital bands causing intestinal obstruction are not frequently encountered in surgical practice and these bands are often difficult to classify and define. We believe that our new classification is a practical communication tool for medical professionals to summarize and clarify the different types of anomalous bands.
Minimising induced drag with weight distribution, lift distribution, wingspan, and wing-structure weight
Authors: Phillips W.F. , Hunsaker D.F. , Taylor J.D. 
Published: March 2020

ABSTRACTBecause the wing-structure weight required to support the critical wing section bending moments is a function of wingspan, net weight, weight distribution, and lift distribution, there exists an optimum wingspan and wing-structure weight for any fixed net weight, weight distribution, and lift distribution, which minimises the induced drag in steady level flight. Analytic solutions for the optimum wingspan and wing-structure weight are presented for rectangular wings with four different sets of design constraints. These design constraints are fixed lift distribution and net weight combined with 1) fixed maximum stress and wing loading, 2) fixed maximum deflection and wing loading, 3) fixed maximum stress and stall speed, and 4) fixed maximum deflection and stall speed. For each of these analytic solutions, the optimum wing-structure weight is found to depend only on the net weight, independent of the arbitrary fixed lift distribution. Analytic solutions for optimum weight and lift distributions are also presented for the same four sets of design constraints. Depending on the design constraints, the optimum lift distribution can differ significantly from the elliptic lift distribution. Solutions for two example wing designs are presented, which demonstrate how the induced drag varies with lift distribution, wingspan, and wing-structure weight in the design space near the optimum solution. Although the analytic solutions presented here are restricted to rectangular wings, these solutions provide excellent test cases for verifying numerical algorithms used for more general multidisciplinary analysis and optimisation.
Born Digital? Digitization and the Birth of the Moroccan National Archives
Authors: El Qadim Nora 
Published: March 2020

Abstract:This article examines the digitization policy of Archives du Maroc (AdM), Morocco’s national archival institution, which was set up in 2011 and opened in 2013. Given its recent creation, the AdM lead us to question the particularity of digitization in archiving policies when included from the start rather than retroactively. Through an analysis of the creation and development of AdM as a public policy connected to national efforts at transparency and “good governance,” I argue that digitization has served as a way of performing modernity through technology and international standards, thus reinforcing the legitimacy of a nascent institution.

AbstractFindings for the roles of dairy products, Ca and vitamin D on ovarian cancer risk remain controversial. We aimed to assess these associations by using an updated meta-analysis. Five electronic databases (e.g. PubMed and Embase) were searched from inception to 24 December 2019. Pooled relative risks (RR) with 95 % CI were calculated. A total of twenty-nine case–control or cohort studies were included. For comparisons of the highest v. lowest intakes, higher whole milk intake was associated with increased ovarian cancer risk (RR 1·35; 95 % CI 1·15, 1·59), whereas decreased risks were observed for higher intakes of low-fat milk (RR 0·84; 95 % CI 0·73, 0·96), dietary Ca (RR 0·71; 95 % CI 0·60, 0·84) and dietary vitamin D (RR 0·80; 95 % CI 0·67, 0·95). Additionally, for every 100 g/d increment, increased ovarian cancer risks were found for total dairy products (RR 1·03; 95 % CI 1·01, 1·04) and for whole milk (RR 1·07; 95 % CI 1·03, 1·11); however, decreased risks were found for 100 g/d increased intakes of low-fat milk (RR 0·95; 95 % CI 0·91, 0·99), cheese (RR 0·87; 95 % CI 0·76, 0·98), dietary Ca (RR 0·96; 95 % CI 0·95, 0·98), total Ca (RR 0·98; 95 % CI 0·97, 0·99), dietary vitamin D (RR 0·92; 95 % CI 0·87, 0·97) and increased levels of circulating vitamin D (RR 0·84; 95 % CI 0·72, 0·97). These results show that whole milk intake might contribute to a higher ovarian cancer risk, whereas low-fat milk, dietary Ca and dietary vitamin D might reduce the risk.
The ‘old books of Glastonbury’ and the Muchelney breviary fragment: London, British Library, Additional 56488, fols. i, 1–5
Authors: Billett Jesse D. 
Published: March 2020

AbstractLondon, British Library, Add. 56488, fols. i, 1–5, is a fragment from a monastic breviary of the first half of the eleventh century, probably made at or for Muchelney Abbey (Somerset). It is here argued on palaeographical, musical and liturgical grounds that this breviary represents a liturgical tradition separate from that of Æthelwold’s network of reformed houses, which imitated the northern French monastery of Corbie. The fragment’s liturgy is based instead on a local ‘secular’ (non-monastic) liturgical tradition that has been minimally supplemented and rearranged to agree with the requirements of the Regula S. Benedicti. The scribe apparently compiled the breviary from several separate exemplars (a collectar, a bible, a homiliary, and what seems to have been a ‘secular’ antiphoner), which may indicate that the liturgy at Muchelney was ‘Benedictinized’ much later than might have been assumed. The same secular tradition seems to be preserved, beneath subsequent layers of modification, in a thirteenth-century Muchelney breviary (London, British Library, Add. 43405–6) and a fifteenth-century ordinal of St Mary’s Abbey, York (Cambridge, St John’s College D. 27). These later sources, while not representing the Benedictine liturgy of the lost ‘old books of Glastonbury’ under Dunstan (as suggested by McLachlan and Tolhurst), are valuable potential witnesses to the otherwise largely unattested Office liturgy used in English minsters before the ‘Benedictine Reform’ of the tenth century.
The social geography of near and far: built environment and residential distance in mid-nineteenth-century New York City
Authors: Baics Gergely 
Published: March 2020

AbstractThis article brings together two Geographical Information Systems (GIS) datasets – building-level land-use data from the 1852–54 Perris Fire Insurance Atlas, and geocoded home addresses from the 1854 city directory – to explore how desirable and undesirable conditions of the built environment accounted for new dynamics of residential separation in mid-nineteenth-century New York. Using spatial analysis, it shows how early forms of residential separation were driven by the desire of elites to create secluded residential neighbourhoods. Further, although stark contrasts delineated the extremes of wealth and poverty, the city's dominant landscape was defined by in-between conditions and subtle variations in built environment and residential distance.

Published: March 2020

AbstractTo compile the findings of studies assessing emotional and behavioral changes in the survivors of the 2011 Fukushima nuclear disaster, we performed a systematic review in August 2019 using four literature databases (PubMed, PsycINFO, Psychology and Behavioral Sciences Collection, and ICHUSHI). Peer-reviewed manuscripts, either in English or Japanese, were included in the searches. Sixty-one studies were retrieved for the review. Of these, 41 studies (67.2%) assessed emotional consequences, 28 studies (45.9%) evaluated behavioral consequences, and 8 studies (13.1%) evaluated both emotional and behavioral outcomes. The main research topic in emotional change was radiation exposure-associated risk perception, as reported in 15 studies. This risk perception included immediate health effects (eg, acute radiation syndrome) as well as future health effects (eg, future cancer and genetic effects). Lowered subjective well-being was reported in eight studies. Six studies reported perceived discrimination/stigmatization in the disaster survivors. The most critical behavioral change was an increase in suicides compared with residents in the whole of Japan or affected by the earthquake and tsunami, but not by the nuclear disaster. Increased rate of alcohol and tobacco use was reported, although the effect on one’s health was inconsistent. As a conclusion, the Fukushima nuclear disaster survivors suffered issues in risk perception, well-being, stigmatization, and alcohol/tobacco use in the first 8 years after the disaster. The present study is important in order to better understand the emotional and behavioral responses to future nuclear/radiological disasters as well as other “invisible” disasters, such as chemical and biological public health crises.
Whole grain intake compared with cereal fibre intake in association to CVD risk factors: a cross-sectional analysis of the National Diet and Nutrition Survey (UK)

Published: March 2020

AbstractObjective:To investigate how intakes of whole grains and cereal fibre were associated to risk factors for CVD in UK adults.Design:Cross-sectional analyses examined associations between whole grain and cereal fibre intakes and adiposity measurements, serum lipid concentrations, C-reactive protein, systolic blood pressure, fasting glucose, HbA1c, homocysteine and a combined CVD relative risk score.Setting:The National Diet and Nutrition Survey (NDNS) Rolling Programme 2008–2014.Participants:A nationally representative sample of 2689 adults.Results:Participants in the highest quartile (Q4) of whole grain intake had lower waist–hip ratio (Q1 0·872; Q4 0·857; P = 0·04), HbA1c (Q1 5·66 %; Q4 5·47 %; P = 0·01) and homocysteine (Q1 9·95 µmol/l; Q4 8·76 µmol/l; P = 0·01) compared with participants in the lowest quartile (Q1), after adjusting for dietary and lifestyle factors, including cereal fibre intake. Whole grain intake was inversely associated with C-reactive protein using multivariate analysis (P = 0·02), but this was not significant after final adjustment for cereal fibre. Cereal fibre intake was also inversely associated with waist–hip ratio (P = 0·03) and homocysteine (P = 0·002) in multivariate analysis.Conclusions:Similar inverse associations between whole grain and cereal fibre intakes to CVD risk factors suggest the relevance of cereal fibre in the protective effects of whole grains. However, whole grain associations often remained significant after adjusting for cereal fibre intake, suggesting additional constituents may be relevant. Intervention studies are needed to compare cereal fibre intake from non-whole grain sources to whole grain intake.
