Geostationary Orbit Transfer with Lunar Gravity Assist from Non-equatorial Launch Site
Authors: Choi Su-Jin , Carrico John , Loucks Mike , Lee Hoonhee , Kwon Sejin 
Published: September 2021

AbstractWe show that it is possible to launch a satellite to Geostationary Equatorial orbit (GEO) from the non-equatorial launch site (Naro Space Center in South Korea) even though that is located in the mid-latitudes of the northern hemisphere. When launched from this site, the equatorial inclination after separation will be 80°. We use a lunar gravity assist (LGA) transfer to avoid the excessive ∆V costs of plane change maneuvers. There are eight possible paths for the LGA; there are four paths consisting of Earth departures and free-return types, and there are two nodes of the Moon’s orbit (ascending and descending). We analyze trajectories over five launch periods for each path using a high-fidelity orbit propagation model. We show that the LGA changes the orbital energy of the “cislunar” free-returns more than for the “circumlunar” free-returns, resulting in less geostationary insertion ∆V for the cislunar free-returns. We also show that the geometrical ∆V variation over the different paths is greater than the seasonal ∆V variation. Our results indicate that an ascending departure and cislunar free-return at the descending node have lower ∆V requirements than the other paths, and lower than described in several previous studies.
A Computational Dual-Process Model of Fixation-Duration Control in Natural Scene Viewing
Authors: Walshe R. Calen , Nuthmann Antje 
Published: September 2021

AbstractResearch on eye-movement control during natural scene viewing has investigated the degree to which the duration of individual fixations can be immediately adjusted to ongoing visual-cognitive processing demands. Results from several studies using the fixation-contingent scene quality paradigm suggest that the timing of fixations adapts to stimulus changes that occur on a fixation-to-fixation basis. Analysis of fixation-duration distributions has revealed that saccade-contingent degradations and enhancements of the scene stimulus have two qualitatively distinct types of influence. The surprise effect begins early in a fixation and is tied to surprising visual events such as unexpected stimulus changes. The encoding effect is tied to difficulties in visual-cognitive processing and occurs relatively late within a fixation. Here, we formalize an existing descriptive account of these two effects (referred to as the dual-process account) by using stochastic simulations. In the computational model, surprise and encoding related influences are implemented as time-dependent changes in the rate at which saccade timing and programming are completed during critical fixations. The model was tested on data from two experiments in which the luminance of the scene image was either decreased or increased during selected critical fixations (Walshe & Nuthmann, Vision Research, 100, 38–46, 2014). A counterfactual method was used to remove model components and to identify their specific influence on the fixation-duration distributions. The results suggest that the computational dual-process model provides a good account for the data from the luminance-change studies. We describe how the simulations can be generalized to explain a diverse set of experimental results.
Pregnancy outcomes after fertility preservation in women with endometrial carcinoma and atypical endometrial hyperplasia: A systematic review and meta-analysis

Published: September 2021

AbstractObjectiveThe objective of the study was to compare the effects of assisted reproductive technology (ART) and spontaneous pregnancy on pregnancy outcomes in women with endometrial carcinoma (EC) and atypical endometrial hyperplasia (AEH) following fertility-sparing treatments.MethodsRelevant studies published through July 2020 were identified from PubMed and Web of Science literature searches. The pregnancy outcomes of ART and spontaneous pregnancy were summarized and compared for women with complete remission of EC/AEH after fertility-sparing treatments. A subgroup analysis was performed based on whether patients had receivedin vitrofertilization and embryo transfer (IVF-ET) treatment. The complete remission and recurrence rates of EC/AEH following fertility-sparing treatments were estimated. The effect of pregnancy on recurrence rates of EC/AEH was also calculated.ResultsSixteen observational studies reporting pregnancy outcomes or recurrence with ART or spontaneous pregnancy for women with EC/AEH after fertility-sparing treatments were included. The complete remission rate of EC/AEH was 81.5% (95%CI, 78%–85%). Compared with spontaneous pregnancy, the pregnancy rate of ART was significantly higher (66.8% vs. 43.7%, OR ​= ​2.64, 95%CI 1.71–4.05,P<0.00001,I2 ​= ​14%). Subgroup analysis showed that the pregnancy rate of IVF-ET was significantly higher than that of spontaneous pregnancy (62.7% vs. 35.1%, OR ​= ​2.85, 95%CI 1.44-5.63,P ​= ​0.003,I2 ​= ​29%). The live birth rate of ART was significantly higher than that of spontaneous pregnancy (75.3% vs. 47.8%, OR ​= ​3.96, 95%CI1.76-8.77,P ​= ​0.0009,I2 ​= ​45%). The recurrence rate of EC/AEH was 31% (95%CI 24%–39%). Clinical pregnancy could reduce the recurrence rate of EC/AEH, but there was no significant evidence of an association.ConclusionsART, especially IVF-ET, could significantly improve pregnancy outcomes in women with EC/AEH receiving fertility-sparing treatments. Following complete remission, ART treatment might be a better option for women with EC/AEH than spontaneous pregnancy.
Women feel more attractive before ovulation: evidence from a large-scale online diary study

Published: September 2021

Abstract
How attractive we find ourselves decides who we target as potential partners and influences our reproductive fitness. Self-perceptions on women's fertile days could be particularly important. However, results on how self-perceived attractiveness changes across women's ovulatory cycles are inconsistent and research has seldomly assessed multiple attractiveness-related constructs simultaneously. Here, we give an overview of ovulatory cycle shifts in self-perceived attractiveness, sexual desirability, grooming, self-esteem and positive mood. We addressed previous methodological shortcomings by conducting a large, preregistered online diary study of 872 women (580 naturally cycling) across 70 consecutive days, applying several robustness analyses and comparing naturally cycling women with women using hormonal contraceptives. As expected, we found robust evidence for ovulatory increases in self-perceived attractiveness and sexual desirability in naturally cycling women. Unexpectedly, we found moderately robust evidence for smaller ovulatory increases in self-esteem and positive mood. Although grooming showed an ovulatory increase descriptively, the effect was small, failed to reach our strict significance level of .01 and was not robust to model variations. We discuss how these results could follow an ovulatory increase in sexual motivation while calling for more theoretical and causally informative research to uncover the nature of ovulatory cycle shifts in the future.
Three Attitudes Towards Nature
Authors: Martin Christian 
Published: September 2021

AbstractIn his introductions to the encyclopaedicPhilosophy of Natureand to theLectures on the Philosophy of Nature, Hegel distinguishes between three ‘attitudes’ (Verhaltensweisen,Einstellungen) towards nature—the theoretical, the practical and the philosophical attitude. According to him there is a certain ‘contradiction’ or tension between our theoretical attitude towards nature, which makes it an object of scientific inquiry, and the practical attitude that we assume as living rational beings who intervene in nature and shape it according to our purposes. This article focuses on how exactly to pinpoint that tension and on how it is resolved in what Hegel calls the ‘philosophical’ or ‘comprehending’ attitude towards nature.
Close Encounters of an Unprecedented Kind: Police and German Enemy Aliens in Britain during the First World War
Authors: Shpayer-Makov Haia 
Published: September 2021

AbstractThe First World War introduced new tasks into British policing. One significant addition was the close and systematic surveillance of aliens residing in Britain, a role never before undertaken by the British police and one that would previously have been considered un-English. During the war, various official bodies participated in the regulation of the lives of foreigners, but the police played a crucial part. Foreigners hailing from enemy countries, particularly Germans, bore the brunt of police attention, which can be described as nothing short of discriminatory and oppressive. This article examines the new responsibilities of the British police for controlling German nationals and the public response to the new policing. It also assesses the police's wartime performance and the implications of their conduct for the lives of these Germans, all of which has hitherto been little explored. The police were widely considered, both by large segments of the British public and in many other countries, as the best police force in the world, morally superior to other constabularies, especially in their relatively tolerant attitudes toward the public. Their conduct in a time of national crisis, and particularly the degree of tolerance they exercised in their relations with a hated, indeed outcast minority, offers an illuminating case study.

AbstractBackgroundNeurodevelopmental disorders (NDs) are associated with experiences of victimization, but mechanisms remain unclear. We explored sex differences and the role of familial factors and externalizing problems in the association between several NDs and violent victimization in adolescence and young adulthood.MethodsIndividuals born in Sweden 1985–1997, residing in Sweden at their 15th birthday, were followed until date of violent victimization causing a hospital visit or death, death due to other causes, emigration, or December 31, 2013, whichever came first. The exposures were diagnoses of attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), intellectual disability (ID) and other NDs. We used three different Cox regression models: a crude model, a model adjusted for familial confounding using sibling-comparisons, and a model additionally adjusted for externalizing problems.ResultsAmong 1 344 944 individuals followed, on average, for 5 years, 74 487 were diagnosed with NDs and 37 765 had a hospital visit or died due to violence. ADHD was associated with an increased risk of violent victimization in males [hazard ratio (HR) 2.56; 95% confidence interval (CI) 2.43–2.70) and females (HR 5.39; 95% CI 4.97–5.85). ASD and ID were associated with an increased risk of violent victimization in females only. After adjusting for familial factors and externalizing problems, only ADHD was associated with violent victimization among males (HR 1.27; 95% CI 1.06–1.51) and females (HR 1.69; 95% CI 1.21–2.36).ConclusionsFemales with NDs and males with ADHD are at greater risk of being victim of severe violence during adolescence and young adulthood. Relevant mechanisms include shared familial liability and externalizing problems. ADHD may be independently associated with violent victimization.
A gradual separation from the world: a qualitative exploration of existential loneliness in old age
Authors: Carr Sam , Fang Chao 
Published: September 2021

AbstractThis study sought to explore qualitatively experiences of existential loneliness (EL) in 80 older people living in retirement communities across the United Kingdom and Australia. Qualitative semi-structured interviews permitted in-depth exploration of issues such as biographical narrative, close relationships, loss, feelings of loneliness and retirement living. It was our intention to conduct a large-scale, deep-listening exercise that would provide further clues about EL in older people and the circumstances that give rise to such feelings. Data provided rich insight into older people's inner lives. Core themes identified loss of close attachments, lack of physical touch and intimacy, deterioration of health and body, and lack of an emotional language through which to express EL as central to older people's experiences. Furthermore, there was a suggestion that the move to retirement living was for many people inextricably connected to their experience of EL. Our data further support and extend the notion that EL can be thought of as a gradual sense of separation from the world and that ageing intensifies a myriad of social, emotional and physical circumstances that prompt its emergence. This sense of existential isolation need not be thought of as exclusive to those experiencing extreme frailty or who face death imminently – our data pointed to a clear and gradual emergence of EL throughout later life.
SCULPTURAL TRADITIONALISM AND INNOVATION IN THE CLASSIC MAYA KINGDOM OF SAK TZ'I', MEXICO
Authors: Matsumoto Mallory E. , Scherer Andrew K. , Golden Charles , Houston Stephen 
Published: September 2021

AbstractIn this article we analyze the content and form of 58 stone monuments at the archaeological site of Lacanjá Tzeltal, Chiapas, Mexico, which recent research confirms was a capital of the Classic Maya polity Sak Tz'i' (“White Dog”). Sak Tz'i' kings carried the titleajaw(“lord”) rather than the epithetk'uhul ajaw(“holy lord”) claimed by regional powers, implying that Sak Tz'i' was a lesser kingdom in terms of political authority. Lacanjá Tzeltal's corpus of sculptured stone, however, is explicitly divergent and indicates the community's marked cultural autonomy from other western Maya kingdoms. The sculptures demonstrate similarities with their neighbors in terms of form and iconographic and hieroglyphic content, underscoring Lacanjá Tzeltal artisans’ participation in the region's broader culture of monumental production. Nevertheless, sculptural experimentations demonstrate not only that lesser courts like Lacanjá Tzeltal were centers of innovation, but that the lords of Sak Tz'i' may have fostered such cultural distinction to underscore their independent political character. This study has broader implications for understanding interactions between major and secondary polities, artistic innovation, and the development of community identity in the Classic Maya world.
La liaison dans un corpus de hits francophones (1956–2017)
Authors: Coutanson Gasparde , Badin Flora 
Published: September 2021

RÉSUMÉDans cette contribution, nous analysons un corpus de chansons ayant accédé à la première place de classements musicaux réalisés pour la France entre 1956 et 2017. Cette base de données nous permet de nous questionner sur le type d’oralité que produit l’industrie du disque francophone. Si les chansons présentent des caractéristiques conceptionnelles relevant de la distance (Koch et Oesterreicher, 2001), quelques traits linguistiques relevés sont pourtant illustratifs d’une proximité conceptionnelle. Nous nous intéressons plus particulièrement aux liaisons dans les chansons, à leur possible réalisation dans ces productions préparées en comparaison avec des corpus spontanés ou de locuteurs professionnels, aux liaisons variables (que nous considérons comme une marque de distance) et à l’évolution diachronique de leur réalisation. Pour mener à bien cette analyse, nous avons utilisé un outil facilitant l’étude sur corpus des liaisons, que nous présenterons. C’est surtout la réalisation de certaines liaisons variables, comme aprèssuis, étaisoujamais, plus spécifiquement réalisées dans notre corpus, qui concourt au caractère distant de ces productions langagières. Au fil du temps, la réalisation des liaisons variables a diminué dans les chansons, par exemple aprèsestou préposition, les rapprochant de productions relevant de la proximité.
Analysis of rating scales: A pervasive problem in bilingualism research and a solution with Bayesian ordinal models
Authors: Veríssimo João 
Published: September 2021

AbstractResearch in bilingualism often involves quantifying constructs of interest by the use of rating scales: for example, to measure language proficiency, dominance, or sentence acceptability. However, ratings are a type of ordinal data, which violates the assumptions of the statistical methods that are commonly used to analyse them. As a result, the validity of ratings is compromised and the ensuing statistical inferences can be seriously distorted. In this article, we describe the problem in detail and demonstrate its pervasiveness in bilingualism research. We then provide examples of how bilingualism researchers can employ an appropriate solution using Bayesian ordinal models. These models respect the inherent discreteness of ratings, easily accommodate non-normality, and allow modelling unequal psychological distances between response categories. As a result, they can provide more valid, accurate, and informative inferences about graded constructs such as language proficiency.

Modeling the Dynamics of Dense Pyroclastic Flows on Venus: Insights Into Pyroclastic Eruptions
Authors: Ganesh Indujaa , McGuire Luke A. , Carter Lynn M. 
Published: September 2021

AbstractOn Venus, relatively young deposits near volcanic and coronal summits with unique radar characteristics have been proposed to be emplaced by pyroclastic density currents (PDCs). The proposed units are laterally extensive, long‐runout deposits showing moderate to high radar backscatter and circular polarization ratio in 12.6 cm wavelength synthetic aperture radar data. Previous studies have hypothesized that a recent resumption of volcanic activity in the form of PDC‐forming eruptions could have emplaced these deposits. We model the dynamics of dense PDCs using a 2D, depth‐averaged framework focusing on regions where stereo‐derived topography coverage is available; this includes the flanks of Irnini Mons, Anala Mons, Didilia Corona, and Pavlova Corona. Two different mechanisms of initiation which includes impulsive collapse of an eruption column and sustained pyroclastic fountaining are considered. The results emphasize the importance of pyroclastic flow fluidization via high pore pressure in emplacing long‐runout deposits along gently sloping (<2°) volcanic flanks. We also show that collapse of columns >1.2–1.4 km tall as well as pyroclastic fountains lasting >400 s with fountain heights of 50 m are capable of generating pyroclastic flows that could emplace some of the smaller deposits studied. For the large deposits at Irnini Mons, more energetic flows resulting from taller column heights would be necessary; the dynamics of such flows under Venus's conditions are not well understood. Distinguishing between the two initiation styles, that is, column collapse and sustained fountaining is not feasible with currently available datasets and would require higher resolution imagery and topography data.

AbstractChip-to-chip and world-to-chip fluidic interconnections are paramount to enable the passage of liquids between component chips and to/from microfluidic systems. Unfortunately, most interconnect designs add additional physical constraints to chips with each additional interconnect leading to over-constrained microfluidic systems. The competing constraints provided by multiple interconnects induce strain in the chips, creating indeterminate dead volumes and misalignment between chips that comprise the microfluidic system. A novel, gasketless superhydrophobic fluidic interconnect (GSFI) that uses capillary forces to form a liquid bridge suspended between concentric through-holes and acting as a fluid passage was investigated. The GSFI decouples the alignment between component chips from the interconnect function and the attachment of the meniscus of the liquid bridge to the edges of the holes produces negligible dead volume. This passive seal was created by patterning parallel superhydrophobic surfaces (water contact angle ≥ 150°) around concentric microfluidic ports separated by a gap. The relative position of the two polymer chips was determined by passive kinematic constraints, three spherical ball bearings seated in v-grooves. A leakage pressure model derived from the Young–Laplace equation was used to estimate the leakage pressure at failure for the liquid bridge. Injection-molded, Cyclic Olefin Copolymer (COC) chip assemblies with assembly gaps from 3 to 240 µm were used to experimentally validate the model. The maximum leakage pressure measured for the GSFI was 21.4 kPa (3.1 psig), which corresponded to a measured mean assembly gap of 3 µm, and decreased to 0.5 kPa (0.073 psig) at a mean assembly gap of 240 µm. The effect of radial misalignment on the efficacy of the gasketless seals was tested and no significant effect was observed. This may be a function of how the liquid bridges are formed during the priming of the chip, but additional research is required to test that hypothesis.
Microdevice for directional axodendritic connectivity between micro 3D neuronal cultures

Published: September 2021

AbstractNeuronal cultures are widely used in neuroscience research. However, the randomness of circuits in conventional cultures prevents accurate in vitro modeling of cortical development and of the pathogenesis of neurological and psychiatric disorders. A basic feature of cortical circuits that is not captured in standard cultures of dissociated cortical cells is directional connectivity. In this work, a polydimethylsiloxane (PDMS)-based device that achieves directional connectivity between micro 3D cultures is demonstrated. The device consists of through-holes for micro three-dimensional (μ3D) clusters of cortical cells connected by microtrenches for axon and dendrite guidance. The design of the trenches relies in part on the concept of axonal edge guidance, as well as on the novel concept of specific dendrite targeting. This replicates dominant excitatory connectivity in the cortex, enables the guidance of the axon after it forms a synapse in passing (an “en passant” synapse), and ensures that directional selectivity is preserved over the lifetime of the culture. The directionality of connections was verified morphologically and functionally. Connections were dependent on glutamatergic synapses. The design of this device has the potential to serve as a building block for the reconstruction of more complex cortical circuits in vitro.
