Graph convolutional networks for traffic forecasting with missing values
Authors: Zuo Jingwei , Zeitouni Karine , Taher Yehia , Garcia-Rodriguez Sandra
Published: December 2022

Traffic forecasting has attracted widespread attention recently. In reality, traffic data usually contains missing values due to sensor or communication errors. The Spatio-temporal feature in traffic data brings more challenges for processing such missing values, for which the classic techniques (e.g., data imputations) are limited: (1) in temporal axis, the values can be randomly or consecutively missing; (2) in spatial axis, the missing values can happen on one single sensor or on multiple sensors simultaneously. Recent models powered by Graph Neural Networks achieved satisfying performance on traffic forecasting tasks. However, few of them are applicable to such a complex missing-value context. To this end, we propose GCN-M, a Graph Convolutional Network model with the ability to handle the complex missing values in the Spatio-temporal context. Particularly, we jointly model the missing value processing and traffic forecasting tasks, considering both local Spatio-temporal features and global historical patterns in an attention-based memory network. We propose as well a dynamic graph learning module based on the learned local-global features. The experimental results on real-life datasets show the reliability of our proposed method.
Is the Statistical Interpretation of Quantum Mechanics ψ-Ontic or ψ-Epistemic?
Authors: Hubert Mario
Published: December 2022

The ontological models framework distinguishes ψ-ontic from ψ-epistemic wave-functions. It is, in general, quite straightforward to categorize the wave-function of a certain quantum theory. Nevertheless, there has been a debate about the ontological status of the wave-function in the statistical interpretation of quantum mechanics: is it ψ-epistemic and incomplete or ψ-ontic and complete? I will argue that the wave-function in this interpretation is best regarded as ψ-ontic and incomplete.

Published: December 2022

1-deoxynojirimycin (DNJ) has certain medicinal value in lowering blood sugar, lowering blood fat, antiviral and anti-tumor, and Mulberry is one of known species with the highest DNJ content. To take full advantage of medicinal benefits of mulberry, the internal relationships of the genetic diversity of SSR markers and DNJ content was assessed in this study, so as to provide the basis for the exploitation and breeding of mulberry resources with high DNJ content. The results showed that the DNJ content in the leaves of the 36 mulberry germplasm resources varied significantly, with the mean value of 1.2794 mg/g, the amplitude of 1.03–1.61 g/g, and the coefficient of variation of 0.1276. Polymorphism was found in by 5 pairs of SSR primers from 36 mulberry germplasm resources, and a total of 32 genotypes were deteced. The mean allele number was 3.8, the mean heterozygosity was 0.62, the polymorphic information content of 0.61. Cluster analysis based on the genetic distance of SSR markers showed that the tested 36 mulberry germplasm resources could be divided into 3 class, and the analysis based on DNJ content showed that they could be divided into 2 clades. Comparison of the two cluster analyses displayed that the DNJ content in mulberry germplasm resources of the same group was similar. The above results revealed that the genetic diversity of SSR markers was similar to the genetic diversity of DNJ content in mulberry leaf.
Potentials of Collaborative Educational Welfare Research - Theorizing Voice Plurality and Social Empowerment
Authors: Smeplass Eli , Cecilia Rapp Anna , Sperling Katarina , Akse Jannicke
Published: December 2022

Childhood marginalization is the result of complicated processes that appears difficult to address for policymakers worldwide. Neo-institutional theory enables studies of the complexity of educational organizations, showing how they evolve in responses to their contradictory surroundings and generate unintended social inequality. Three Nordic municipalities are currently participating in a project that focuses on the increasing polarization between exposed and privileged schools in urban areas and on the significance of institutional and organizational factors in their local welfare models in ensuring childhood equity. The project we report on combines data in contrasting urban school areas. After showing some examples of voices in the project, the authors discuss how municipal actors are informed about social problems in school organizations yet lack research-based tools to counteract social inequality in education. They theorize how collaboration between researchers and welfare providers can contribute to counteract social inequality. Lessons from the project indicate a need for further collaboration between different stakeholders that includes different voices to ensure that research on childhood inequality is relevant and has an impact.
Neural manifold analysis of brain circuit dynamics in health and disease
Authors: Mitchell-Heggs Rufus , Prado Seigfred , Gava Giuseppe P. , Go Mary Ann , Schultz Simon R.
Published: December 2022

Recent developments in experimental neuroscience make it possible to simultaneously record the activity of thousands of neurons. However, the development of analysis approaches for such large-scale neural recordings have been slower than those applicable to single-cell experiments. One approach that has gained recent popularity is neural manifold learning. This approach takes advantage of the fact that often, even though neural datasets may be very high dimensional, the dynamics of neural activity tends to traverse a much lower-dimensional space. The topological structures formed by these low-dimensional neural subspaces are referred to as “neural manifolds”, and may potentially provide insight linking neural circuit dynamics with cognitive function and behavioral performance. In this paper we review a number of linear and non-linear approaches to neural manifold learning, including principal component analysis (PCA), multi-dimensional scaling (MDS), Isomap, locally linear embedding (LLE), Laplacian eigenmaps (LEM), t-SNE, and uniform manifold approximation and projection (UMAP). We outline these methods under a common mathematical nomenclature, and compare their advantages and disadvantages with respect to their use for neural data analysis. We apply them to a number of datasets from published literature, comparing the manifolds that result from their application to hippocampal place cells, motor cortical neurons during a reaching task, and prefrontal cortical neurons during a multi-behavior task. We find that in many circumstances linear algorithms produce similar results to non-linear methods, although in particular cases where the behavioral complexity is greater, non-linear methods tend to find lower-dimensional manifolds, at the possible expense of interpretability. We demonstrate that these methods are applicable to the study of neurological disorders through simulation of a mouse model of Alzheimer’s Disease, and speculate that neural manifold analysis may help us to understand the circuit-level consequences of molecular and cellular neuropathology.
Profiles of Emotional Separation and Parental Trust from Adolescence to Emerging Adulthood: Age Differences and Associations with Identity and Life Satisfaction
Authors: Sugimura Kazumi , Hihara Shogo , Hatano Kai , Nakama Reiko , Saiga Satoko , Tsuzuki Manabu
Published: December 2022

Youth become psychologically independent by emotionally separating from their parents and simultaneously developing a sense of trust in them. While these relational components have been addressed separately, studies focusing on the change in dynamics of these components are lacking. This study examined profiles of parent–youth relationship quality based on emotional separation and parental trust, age differences in the prevalence of these profiles, and age differences in the associations between the profiles, identity, and life satisfaction. Participants included 14,428 youth living in Japan from five age groups (44.8% girls/women; Mage = 20.6 years; range = 12–25 years). Six profiles were identified: healthy–independent, unhealthy–independent, balanced, moderate/ambivalent, connected, and distant. The connected profile was predominant among early adolescents, while the healthy–independent profile was predominant among late adolescents and early and middle emerging adults. Among all age groups, identity synthesis was the highest in the healthy–independent profile, and life satisfaction was the highest and identity confusion was the lowest in the healthy–independent and connected profiles. These findings indicate that young people navigate the process of becoming independent from their parents by balancing emotional separation and parental trust, and this balance relates to identity development and life satisfaction.
Hear No Sievers, See No Sievers: Metrics and the Eddic Commentary Tradition
Authors: Males Mikael
Published: December 2022

This article explores a gradual shift towards metrical and linguistic imprecision in the four major commentaries on the Old Norse Eddic poems produced from the 1930s to today. This trend both affects and reflects the state of Eddic scholarship at large. Many scholars today do not avail themselves of metrical and linguistic criteria in the dating and textual restitution of Eddic poems but approach these issues either with agnosticism or by presenting vague arguments in favour of particular dates or variants. During the last three decades, however, testing along many parameters has placed the essentials of Eduard Sievers’ metrical analysis (1893) beyond reasonable doubt, which means that the gradual abandonment of precise description has taken place in a context where the preconditions for such description were improving. These analytical advances and mainstream Eddic scholarship have yet to meet, and the present article aims to facilitate such a convergence. Furthermore, since the Eddic commentaries will remain indispensable heuristic tools for the foreseeable future, the field of Old Norse philology stands to gain from a concise description of the implicit metrical and linguistic assumptions guiding their analysis.
Material Dependence and Kant’s Refutation of Idealism
Authors: Heidemann Dietmar
Published: December 2022

The paper argues that in the Critique of Pure Reason Kant develops two anti-sceptical strategies. In the Fourth Paralogism (CPR A) he believes himself able to refute the sceptic by demonstrating that external perception is immediate. This strategy is rather unconvincing. In the Refutation of Idealism (CPR B) Kant promotes the material dependence of inner sense on outer sense. I show that Kant’s argument for material dependence has been widely overlooked, even though it is the strongest argument against external world scepticism he develops, since it anticipates mental content externalism while preserving transcendental idealism and empirical realism.
Patients’ Perspective in Hereditary Ataxia
Authors: Gorcenco Sorina , Karremo Christin , Puschmann Andreas
Published: December 2022

Hereditary ataxia represents a heterogeneous group of rare disorders with the chronic progression of motor symptoms that often become debilitating. Many forms include additional neurological, cognitive, or other symptoms. Most of these disorders lack specific treatment. We aimed to investigate aspects of patients’ quality of life, experiences, and expectations. Patients with a diagnosis of hereditary ataxia were identified from our center’s diagnostic register, direct referrals, and from a patient organization. We designed a questionnaire with 32 multiple-choice or open-ended questions on disability and impairment of daily life activities, the perceived effect of symptomatic and supportive therapies, coping strategies, and how they used and experienced various sources of information about their neurological disease. We also included the EQ-5D-3L quality-of-life instrument. Results were analyzed statistically for gender, age, and groups with and without a genetic diagnosis, and were compared to published data from the general population. Seventy-five patients returned the questionnaire. Patients reported considerable disease-related disability and impairment and had significantly lower quality-of-life scores than the general population. Physiotherapy and support from family or friends were important for patients’ overall well-being. Patients with a genetic diagnosis had a lower average age at onset and felt more well-informed about their disease than patients without a genetic diagnosis. Patients used internet sources but relied primarily on their doctors to obtain information about their disease. Our study provides insights into hereditary ataxia patients’ experiences that can lead to improvements in medical and nursing care for these patients.
Application of machine learning to determine the shear stress and filtration loss properties of nano-based drilling fluid
Authors: Ning Yee Cai , Ridha Syahrir , Ilyas Suhaib Umer , Krishna Shwetank , Dzulkarnain Iskandar , Abdurrahman Muslim
Published: December 2022

A detailed understanding of the drilling fluid rheology and filtration properties is essential to assuring reduced fluid loss during the transport process. As per literature review, silica nanoparticle is an exceptional additive to enhance drilling fluid rheology and filtration properties enhancement. However, a correlation based on nano-SiO2-water-based drilling fluid that can quantify the rheology and filtration properties of nanofluids is not available. Thus, two data-driven machine learning approaches are proposed for prediction, i.e. artificial-neural-network and least-square-support-vector-machine (LSSVM). Parameters involved for the prediction of shear stress are SiO2 concentration, temperature, and shear rate, whereas SiO2 nanoparticle concentration, temperature, and time are the inputs to simulate filtration volume. A feed-forward multilayer perceptron is constructed and optimised using the Levenberg–Marquardt learning algorithm. The parameters for the LSSVM are optimised using Couple Simulated Annealing. The performance of each model is evaluated based on several statistical parameters. The predicted results achieved R2 (coefficient of determination) value higher than 0.99 and MAE (mean absolute error) and MAPE (mean absolute percentage error) value below 7% for both the models. The developed models are further validated with experimental data that reveals an excellent agreement between predicted and experimental data.
Modification of starch using alkali, adipic acid, and mustard oil in search of an improved biomaterial
Authors: Mahmud Md. Arif
Published: December 2022

This study aimed to modify starch using a combination of alkali and adipic acid and mustard oil to improve the mechanical and absorbency properties. Acid and oil were applied for uniform and quick swelling and gelatinization of starch, while alkali helped the whole gelatinization process at a lower temperature at a uniform rate. Chain scissoring via oxidation and reformation of bonds within the adjacent chains have resulted in the modified structure of starch. The material underwent several tests, including mechanical, thermal, and absorbency tests. The maximum tensile strength after modification was recorded at 8.58 MPa, while the absorbency reduced to below 60%, which is generally found above 150% in native starch. The thermal properties were found to be the least affected by the modification. Comparison with other modified starches showed considerable success, but the most significant aspect was found to be the low product cost. Comparison with other biopolymers and synthetic polymers also proved some improvements in this study.

Pedagogical features include 'Why You Might Care' sections, quick-reference chapter guides and key terms and results summaries, problem-solving and writing tips, 'Taking it Further' asides with more technical details, and around 1700 exercises, 435 worked examples, and 480 figures.
A Review of Blastozoan Echinoderm Respiratory Structures
Authors: Sheffield Sarah L. , Limbeck Maggie R. , Bauer Jennifer E. , Hill Stephen A. , Nohejlová Martina
Published: December 2022

Echinoderms have evolved diverse and disparate morphologies throughout the Phanerozoic. Among them, blastozoans, an extinct group of echinoderms that were an important component of Paleozoic marine ecosystems, are primarily subdivided into groups based on the morphology of respiratory structures. However, systematic and phylogenetic research from the past few decades have shown that respiratory structures in blastozoans are not group-defining and they have re-evolved throughout echinoderm evolution. This Element provides a review of the research involving blastozoan respiratory structures, along with research concerning the morphology, paleoecology, and ontogeny of each of the major groupings of blastozoans as it relates to their corresponding respiratory structures. Areas of future research in these groups are also highlighted.
Manifestations of environmental principles in bridging scientific context, reasoning and behaviour: framework in the development of environmental education programmes in the Philippines
Authors: Malaluan Lorie E. , Espinosa Allen A. , Duad Virgil D.
Published: December 2022

This study explored the relationship between scientific context (SC), scientific reasoning (SR), and scientific behaviour (SB) across the environmental principles to show their significance as essential scientific competencies in the development of environmental programmes in the Philippine K-12 curriculum in a process where environmental education has a key role to play. One hundred and seventy-seven high school students from Bongabong, Oriental Mindoro in the Philippines were selected through the cluster purposive probabilistic sampling method. A descriptive normative survey method of research was employed in this study. The students’ SC had a high relationship with their SR, which is a direct indicator of SB. This was a sign that SC, SR, and SB all work together in a continuous way. Findings of this study will serve as baseline information for the framework of environmental education programmes through science, in the K-12 Philippine Science curriculum. So, when students learn things in the real world, they gain environmental effect, which is thought to be a key reason why people act in ways that are good for the environment and an important goal of environmental education.

associated with the thresholding greedy algorithm in terms of a new generation of parameters that modulate accurately some features of a general basis. This fine tuning of constants allows us to provide an answer to the question raised by Temlyakov in 2011 to find a natural sequence of greedy-type parameters for arbitrary bases in Banach (or quasi-Banach) spaces which combined linearly with the sequence of unconditionality parameters

The butterfly effect and the transition to turbulence in a stratified shear layer
Authors: Liu Chih-Lun , Kaminski Alexis K. , Smyth William D.
Published: December 2022

In a stably stratified shear layer, multiple competing instabilities produce sensitivity to small changes in initial conditions, popularly called the butterfly effect (as a flapping wing may alter the weather). Three ensembles of 15 simulated mixing events, identical but for small perturbations to the initial state, are used to explore differences in the route to turbulence, the maximum turbulence level and the total amount and efficiency of mixing accomplished by each event. Comparisons show that a small change in the initial state alters the strength and timing of the primary Kelvin–Helmholtz instability, the subharmonic pairing instability and the various three-dimensional secondary instabilities that lead to turbulence. The effect is greatest in, but not limited to, the parameter regime where pairing and the three-dimensional secondary instabilities are in strong competition. Pairing may be accelerated or prevented; maximum turbulence kinetic energy may vary by up to a factor of 4.6, flux Richardson number by 12 %–15 % and net mixing by a factor of 2.
A Capabilities Framework for Dynamic Competition: Assessing the Relative Chances of Incumbents, Start-Ups, and Diversifying Entrants
Authors: Murmann Johann Peter , Vogt Fabian
Published: December 2022

This essay argues that to assess the likelihood that incumbent firms will successfully make the required transformations to their strategy and operations in the face of technological transformations, it is not sufficient to investigate their dynamic capabilities. Whether an incumbent is likely to succeed in its effort to change itself via dynamic capabilities depends also on how quickly start-ups or diversifying entrants can build ordinary capabilities to offer the new technology at scale. We offer a framework to assess dynamic competition that integrates both ordinary and dynamic capabilities into the analysis by systematically comparing incumbents, start-ups, and diversifying entrants. We illustrate the framework with a case study of electric vehicles and aim to show how crucial such comparative analyses are for making well-founded predictions about the likelihood that incumbents will be able to maintain their leadership positions in the future.
NORMAL AND IRREDUCIBLE ADIC SPACES, THE OPENNESS OF FINITE MORPHISMS, AND A STEIN FACTORIZATION
Authors: MANN LUCAS
Published: December 2022

We transfer several elementary geometric properties of rigid-analytic spaces to the world of adic spaces, more precisely to the category of adic spaces which are locally of (weakly) finite type over a non-archimedean field. This includes normality, irreducibility (in particular, irreducible components), and a Stein factorization theorem. Most notably, we show that a finite morphism in our category of adic spaces is automatically open if the target is normal and both source and target are of the same pure dimension. Moreover, our version of the Stein factorization theorem includes a statement about the geometric connectedness of fibers which we have not found in the literature of rigid-analytic or Berkovich spaces.
“On Reading Mau Mau”
Authors: Alvarado Christian
Published: December 2022

During the so-called “era decolonization” in Africa, few historical events held more salience than what is most commonly known as the Mau Mau Uprising in Kenya (which covered the period from 1952 to 1960). This article examines not only how tropes about the nature and origins of Mau Mau were and are deployed across different semiotic landscapes, but also the ways in which their operations are made manifest through practices of reading. I argue that we should consider the idea of Mau Mau—whether it be central to a text or present a mere detail—as a catalyst through which broader claims are made, especially as they relate to the nature of history and the semiotic dimensions of the events that populate it. This article shows this through conducting a “tropology” of Mau Mau, in which the suffix -ology underscores reading its tropes as a particular mode of studying it.
A New Jerusalem: Flavius Josephus in Early America
Authors: Stinson Kristofer
Published: December 2022

This article argues that the first-century Jewish historian, Titus Flavius Josephus, was of central importance to early American Protestants as they wrestled with how to construct a divinely upheld polity and with who would be included within it. By tracing the prefaces to the many editions of Josephus that were published in the eighteenth and nineteenth centuries, it becomes clear that many Protestant readers in America felt torn between two competing identities: Rome and Israel. Scholars of early America are familiar with both labels. But as many early Americans knew from Josephus, those images were not always complementary. In fact, as they pondered over the account of the decimation of the first Jerusalem at the hands of Rome, it became clear that there might be something antithetical in those ancient models. This article argues that Josephus's histories enabled Americans to hold together the tensions in their national identity and ancient imagination that envisioned the United States as both a new Rome and a New Jerusalem. As a foundation, Josephus breathed life and legitimacy into the developing American culture. By neglecting to account for Josephus in this era, scholars have overlooked one of the most pervasive stories that formed the character and understanding of American Protestantism.
Waldensianism Before Waldo: The Myth of Apostolic Proto-Protestantism in Antebellum American Anti-Catholicism
Authors: Young Samuel L.
Published: December 2022

Between 1820 and 1850, American presses generated an enormous amount of literature devoted to the myth of apostolic Waldensianism. Though the Waldenses began as a lay reform movement in the twelfth century, speculations about their apostolic origin were popularized in the seventeenth and eighteenth centuries. This historical construction gave American Protestants a versatile rhetorical weapon against an increasingly encroaching Roman Catholicism. The apostolicity of Waldensianism allowed Protestants to trace their teachings not only to scripture but through the middle ages and the early church, providing a ready answer to Catholic accusations of Protestant novelty. Additionally, re-narrating the history of Waldensian persecution at the hand of Catholics reinforced nativist conceptions of Catholicism as a violently tyrannical religion, and became a call to action for Protestants to resist Rome's attempt to gain power in the United States. Though the myth of apostolic Waldensianism was widely held by American Protestants, by 1850 it became largely untenable. Historians on both side of the Atlantic contextualized the group as a medieval phenomenon, rather than the remnant of apostolic Protestantism.
Changes in sleep performance and chronotype behaviour after vestibular rehabilitation in unilateral vestibular hypofunction

Published: December 2022

Objective

This study aimed to investigate changes in sleep parameters and self-perceived sleep quality in unilateral vestibular hypofunction participants after vestibular rehabilitation.

Method

Forty-six unilateral vestibular hypofunction participants (before and after vestibular rehabilitation) along with a control group of 60 healthy patients underwent otoneurological examination, a one-week actigraphy sleep analysis and a series of self-report and performance measures.

Results

After vestibular rehabilitation, unilateral vestibular hypofunction participants showed a significant score decrease in the Pittsburgh Sleep Quality Index, a self-rated reliable questionnaire depicting sleep quality during the last month, as well as a reduction in sleep onset latency and an increase in total sleep time, indicating an objective improvement in sleep quality as measured by actigraphy analysis. However, after vestibular rehabilitation, unilateral vestibular hypofunction participants still showed statistically significant differences with respect to the control group in both self-rated and objective measurements of sleep quality.

Conclusion

Vestibular rehabilitation may impact on sleep performance and chronotype behaviour, possibly by opposing long-term structural changes along neural pathways entangled in sleep activity because of the deafferentation of the vestibular nuclei.
Tackling the adverse health effects of excess body fat in breast cancer: where does physical activity fit in?
Authors: Saxton JM , Wilson C
Published: December 2022

Weight gain is commonly observed during and after breast cancer treatment due to chemotherapy and endocrine therapies, induced menopause, changes in metabolism and food intake and decreased physical activity. Systematic reviews show that women who are overweight or obese at diagnosis, and those who gain weight, have poorer breast cancer survival outcomes than women of a healthy weight, irrespective of menopausal status. Excess body weight after breast cancer also increases the risk of type 2 diabetes mellitus and CVD. The adverse impact of excess body weight on survival outcomes is clearly shown for women with oestrogen receptor-positive (ER+) breast cancer, which accounts for 70 % of all breast cancer cases. Higher body fat is thought to increase the risk of ER+ recurrence because of increased aromatase activity. However, this could be compounded by other risk factors, including abnormal insulin and adipokine metabolism, impaired anti-tumour immunity and chronic low-grade systemic inflammation. Observational evidence linking poorer survival outcomes with excess body fat and low physical activity in women recovering from early-stage curative-intent breast cancer treatment is reviewed, before reflecting on the proposed biological mechanisms. The issues and sensitivities surrounding exercise participation amongst overweight breast cancer patients is also discussed, before providing an overview of the co-design process involved in development of an intervention (support programme) with appropriate content, structure and delivery model to address the weight management challenges faced by overweight ER+ breast cancer patients.
The question of Icebergs: a cryo-history of Arctic submarine cables
Authors: Abildgaard Mette Simonsen
Published: December 2022

“The Question of Icebergs” is a cryo-history (Sörlin, 2015) of Arctic infrastructures: How has ice and snow shaped communication infrastructures in the Arctic by both drawing in and deterring interest in travelling through, connecting with and building in the region? This study follows the case of the 160-year-old plans for “The Northern Route,” a transatlantic telegraph which would have placed Greenland, Iceland and the Faroe Islands at the centre of transatlantic communication in the early 1860s. I draw on Actor-Network Theory and postcolonial studies to trace how notions of the Arctic Sublime, a dependency on “credible ice witnesses,” local ice knowledges and the “politics of comparison” influenced the eventual abandonment of the route, where Arctic territories were (dis)regarded and considered as mere “substrate” for infrastructure. I argue that this cryo-history of Arctic telecommunication infrastructures is an essential contribution to a new socio-technical agenda in cable studies, which shows how established logics about who to connect, and where, still influence infrastructural development in the region today.
Capital and Kin: English Women's Intimate Networks and Property in Barbados
Authors: Ewen Misha
Published: December 2022

This article explores how women in England, using a range of economic and legal tools and methods, managed wealth and property in Barbados during the seventeenth century. Being distant from the colony had implications for how English women managed their property in Barbados, as direct oversight was impossible. Instead, women were forced to broker arrangements with overseers and agents who could act on their behalf. We can make sense of how they established these connections through the lens of women's intimate networks, as they appointed trusted friends, family, and associates to manage their affairs. Women's intimate networks are a lens through which we can explain not just how women acquired property, but also their continued investment in plantation economies and slavery during the first decades of English colonisation in Barbados.
Virtual global positioning system construction approach for unmanned surface vessel based on Dempster–Shafer theory and broad learning framework
Authors: Zhang Chuang , Cao Chunyan , Kang Kaihang , Guo Chen , Guo Muzhuang
Published: December 2022

Integrated navigation systems made up of a strap-down inertial navigation system (SINS) and global positioning system (GPS) are increasingly being used to improve the position, speed, and attitude information of unmanned surface vessels (USV). However, a GPS outage could occur due to the dependence of GPS performance on the external environment and the number of available satellites. This study uses an innovative combination of Dempster–Shafer (DS) theory and broad learning (BL) method to design a SINS/GPS integrated navigation system. First, the velocity and position information derived from the SINS and their corresponding GPS were fused using DS fusion rules, while the SINS error was modelled using the BL method. A ‘virtual’ GPS was then designed using the proposed DS–BL approach to provide the speed and position information when the GPS signal was interrupted, thereby ensuring the continuous navigation of the USV. The results of both simulation and sea trial demonstrate that the proposed virtual GPS estimation approach is effective, and the navigational accuracy of the proposed method is superior to other methods.
Associations between livestock keeping, morbidity and nutritional status of children and women in low- and middle-income countries: a systematic review

Published: December 2022

Livestock keeping can positively influence the nutritional status of populations and households through increased consumption of animal-source foods (ASF) and other indirect pathways, but can also adversely affect health by increasing the risk of diseases. We conducted a systematic review synthesising the current state of knowledge on the associations among livestock keeping, infectious disease and the nutritional status of children under 5 years and women of reproductive age in low- and lower–middle-income countries (LMICs). A comprehensive search of 12 electronic databases and grey literature sources published from 1991 to the end of December 2020 was conducted. Investigations exploring relationships between livestock keeping and risk of infectious disease transmission and nutritional status were selected using pre-defined inclusion criteria. After screening and filtering of 34,402 unique references, 176 references were included in the final synthesis. Most (160/176, 90.1%) of the references included in the final synthesis were from sub-Saharan Africa (SSA) and Asia. About two out of every five (42%) studies reviewed showed that livestock production is associated with improved height-for-ageZscores (HAZ) and weight-for-length/heightZscores (WHZ), while close to a third (30.7%) with improved weight-for-ageZscores (WAZ). Similarly, livestock production showed a positive or neutral relationship with women’s nutritional status in almost all the references that reported on the topic. Conversely, four-fifths (66/81, 79.5%) of the references reporting on infection and morbidity outcomes indicated that livestock keeping is linked to a wide range of infectious disease outcomes, which are spread primarily through water, food and insects. In conclusion, in many LMIC settings, livestock production is associated with better nutritional outcomes but also a higher risk of disease transmission or morbidity among women and children.

Protein digestion and absorption: the influence of food processing
Authors: Loveday Simon M.
Published: December 2022

The rates of dietary protein digestion and absorption can be significantly increased or decreased by food processing treatments such as heating, gelling and enzymatic hydrolysis, with subsequent metabolic impacts, e.g. on muscle synthesis and glucose homeostasis.

This review examines in vivo evidence that industrial and domestic food processing modify the kinetics of amino acid release and absorption following a protein-rich meal. It focuses on studies that used compositionally-matched test meals processed in different ways.

Food processing at extremely high temperature at alkaline pH and/or in the presence of reducing sugars can modify amino acid sidechains, leading to loss of bioavailability. Some protein-rich food ingredients are deliberately aggregated, gelled or hydrolysed during manufacture. Hydrolysis accelerates protein digestion/absorption and increases splanchnic utilisation. Aggregation and gelation may slow or accelerate proteolysis in the gut, depending on the aggregate/gel microstructure.

Milk, beef and eggs are heat processed prior to consumption to eliminate pathogens and improve palatability. The temperature and time of heating affect protein digestion and absorption rates, and effects are sometimes non-linear. In light of a dietary transition away from animal proteins, more research is needed on how food processing affects digestion and absorption of non-animal proteins.

Food processing modifies the microstructure of protein-rich foods, and thereby alters protein digestion and absorption kinetics in the stomach and small intestine. Exploiting this principle to optimise metabolic outcomes requires more human clinical trials in which amino acid absorption rates are measured and food microstructure is explicitly considered, measured and manipulated.
Genetic risk of AUDs and childhood impulsivity: Examining the role of parenting and family environment
Authors: Su Jinni , Trevino Angel , Jamil Belal , Aliev Fazil
Published: December 2022

This study examined the independent and interactive effects of genetic risk for alcohol use disorder (AUD), parenting behaviors, and family environment on childhood impulsivity. Data were drawn from White (n = 5,991), Black/African American (n = 1,693), and Hispanic/Latino (n = 2,118) youth who completed the baseline assessment (age 9–10) and had genotypic data available from the Adolescent Brain Cognitive Development Study. Participants completed questionnaires and provided saliva or blood samples for genotyping. Results indicated no significant main effects of AUD genome-wide polygenic scores (AUD-PRS) on childhood impulsivity as measured by the UPPS-P scale across racial/ethnic groups. In general, parental monitoring and parental acceptance were associated with lower impulsivity; family conflict was associated with higher impulsivity. There was an interaction effect between AUD-PRS and family conflict, such that family conflict exacerbated the association between AUD-PRS and positive urgency, only among Black/African American youth. This was the only significant interaction effect detected from a total of 45 tests (five impulsivity dimensions, three subsamples, and three family factors), and thus may be a false positive and needs to be replicated. These findings highlight the important role of parenting behaviors and family conflict in relation to impulsivity among children.
Two approximate symmetry frameworks for nonlinear partial differential equations with a small parameter: Comparisons, relations, approximate solutions

The frameworks of Baikov–Gazizov–Ibragimov (BGI) and Fushchich–Shtelen (FS) approximate symmetries are used to study symmetry properties of partial differential equations with a small parameter. In general, it is shown that unlike the case of ordinary differential equations (ODEs), unstable BGI point symmetries of unperturbed partial differential equations (PDEs) do not necessarily yield local approximate symmetries for the perturbed model. While some relations between the BGI and FS approaches can be established, the two methods yield different approximate symmetry classifications. Detailed classifications are presented for two nonlinear PDE families. The second family includes a one-dimensional wave equation describing the wave motion in a hyperelastic material with a single family of fibers. For this model, approximate symmetries can be used to compute approximate closed-form solutions. Wave breaking times are found numerically and using the approximate solutions, which yield comparable results.

A 16-month-old girl was referred for tachycardia and upper respiratory tract infection. Echocardiographic examination revealed pericardial effusion, mild mitral regurgitation, and left ventricle systolic dysfunction. Patient was positive for Parainfluenza type 4 virus. Her laboratory tests revealed increased troponin I level. The patient was treated with intravenous immunoglobulin considering acute viral myopericarditis. Two weeks after treatment, midventricular hypertrophy was detected.
To Read or Not to Read: Trialling an Extensive Reading Program in a Year 10 Latin Classroom
Authors: Cooper Melissa
Published: December 2022

Reading is an essential part of learning a language. During my postgraduate (PGCE) teacher-training placement in the UK, I observed extensive reading being used in Modern Foreign Languages (MFL) and English classrooms but saw no evidence for it in the Latin classroom. However, the practice is gaining popularity in the United States as part of Comprehensible Input-based teaching. I was interested to see if extensive reading could be introduced in my classroom without any accompanying spoken Latin and if students would be interested in it. So, I decided to try an extensive reading program for my PGCE research project. The program was positively received by the majority of students, who felt that their Latin ability had improved even after only a handful of sessions, and who appreciated the relatively stressless activity that warmed up their ‘Latin brains’. Many commented that they wanted to read for longer. This very short trial of an extensive reading program gives me much hope for a longer trial or even a permanent program in the future. I also hope that this will encourage others to try bringing extensive reading and its benefits into their classrooms.

Abstract: Introduction: In recent years, evidence has been accumulating that interpersonal violence (IV) in sports coaching situations has detrimental psychopathological effects. IV victimization not only produces traditional adverse symptoms, but also impairs psychological functioning related to self-evaluation and interpersonal relationships in personality development. We designed this study to explore the psychopathological damage caused by IV experiences in Japanese sports coaching situations from the perspective of PTSD and moral injury (MI). Methods: We conducted a Web-based aggregate survey using convenience sampling. Japanese university undergraduates ( N=196, age range 18-23 years) participated in the study. We used hierarchical multiple regression and simple slope analyses to examine quantitative data after controlling for covariates. Results: There was a significant main effect of experiencing psychological violence and MI on several PTSD symptoms, including intrusion, avoidance, and hyperarousal. In addition, a high frequency of experiencing psychological violence enhanced intrusion and hyperarousal symptoms only when causes MI. Conclusion: These results are consistent with previous studies that identified IV-related mental health harms. The result also indicate that the damage caused by IV in sports contexts is complex and aggravated by the deep intrinsic and moral emotional wounds. The primary findings of this study are crucial for protecting athlete’ human rights, further enhancing sports leadership education, and for proactive consideration of preventive intervention strategies.
A Common Measurement Scale for Self-Report Instruments in Mental	Health Care

Abstract: The diversity of measures in clinical psychology hampers a straightforward interpretation of test results, complicates communication with the patient, and constitutes a challenge to the implementation of measurement-based care. In educational research and assessment, it is common practice to convert test scores to a common metric, such as T scores. We recommend applying this also in clinical psychology and propose and test a procedure to arrive at T scores approximating a normal distribution that can be applied to individual test scores. We established formulas to estimate normalized T scores from raw scale scores by regressing IRT-based θ scores on raw scores. With data from a large population and clinical samples, we established crosswalk formulas. Their validity was investigated by comparing calculated T scores with IRT-based T scores. IRT and formulas yielded very similar T scores, supporting the validity of the latter approach. Theoretical and practical advantages and disadvantages of both approaches to convert scores to common metrics and alternative approaches are discussed. Provided that scale characteristics allow for their computation, T scores will help to better understand measurement results, which makes it easier for patients and practitioners to use test results in joint decision-making about the course of treatment.

Reconstructing the tectonic architecture of the southern Altaids is of great importance to piece together the continental growth history of the Central Asian continent. In this paper, we address the subduction‐accretion process of the Paleo‐Tianshan Ocean, one branch of the South Tianshan Ocean, in the southern Altaids, through a detailed geological and geochemical investigation of the Wulanmoren Accretionary Complex (WAC). The WAC is composed of ophiolitic mélanges, ocean plate stratigraphy mélanges, and turbiditic coherent units. In this study, we present key geological, petrological, and geochemical evidence indicating back‐arc and ocean island affinity of the igneous rocks of the WAC. Zircon U‐Pb dates of these rocks ages range between 380.2 ± 1.3 and 302.0 ± 5.3 Ma. The sedimentary matrix units of the mélanges were deposited in the Early Devonian (∼405 Ma) to the Late Triassic (∼222 Ma), rather than Silurian strata as previously thought. However, the ages of some detrital zircons in the sedimentary matrix are Precambrian, pointing to a complex evolution involving multiple ocean island terrains and island arcs of different ages that accreted from the mid‐Paleozoic to the Early Mesozoic.
