Influence of plastic recycling—a feasibility study for additive manufacturing using glycol modified polyethylene terephthalate (PETG)
Authors: Bremer Mats , Janoschek Lukas , Kaschta Denis , Schneider Nick , Wahl Michael 
Published: April 2022

AbstractThis paper presents a feasibility study for the production of recycled glycol modified polyethylene terephthalate (PETG) material for additive manufacturing. Past studies showed a variety of results for the recycling of 3D-printing material, therefore the precise effect on the material properties is not completely clear. For this work, PETG waste of the same grade was recycled once and further processed into 3D printing filament. The study compares three blend ratios between purchased plastic pellets and recycled pellets to determine the degradation effect of one recycling cycle and possible blend ratios to counter these effects. Furthermore, the results include a commercially available filament. The comparison uses the filament diameter, the dimensional accuracy of the printed test specimen and mechanical properties as quality criteria. The study shows that the recycled material has a minor decrease concerning the tensile strength and Young’s modulus.

Published: April 2022

Abstract
This special issue of Reproductive Sciences is focusing on ethnic health disparity and its impact on (fe)male reproduction. Indeed, studies regarding underlying mechanisms, interventions and prognosis in reproduction are underexposed for the non-White male and female. Here, we call for documentation of race and ethnicity in the analysis and management of couples with recurrent pregnancy loss.

Published: April 2022

Abstract
Purpose of Review
The paper discusses how robotics and autonomous systems (RAS) are being deployed to decarbonise agricultural production. The climate emergency cannot be ameliorated without dramatic reductions in greenhouse gas emissions across the agri-food sector. This review outlines the transformational role for robotics in the agri-food system and considers where research and focus might be prioritised.

Recent Findings
Agri-robotic systems provide multiple emerging opportunities that facilitate the transition towards net zero agriculture. Five focus themes were identified where robotics could impact sustainable food production systems to (1) increase nitrogen use efficiency, (2) accelerate plant breeding, (3) deliver regenerative agriculture, (4) electrify robotic vehicles, (5) reduce food waste.

Summary
RAS technologies create opportunities to (i) optimise the use of inputs such as fertiliser, seeds, and fuel/energy; (ii) reduce the environmental impact on soil and other natural resources; (iii) improve the efficiency and precision of agricultural processes and equipment; (iv) enhance farmers’ decisions to improve crop care and reduce farm waste. Further and scaled research and technology development are needed to exploit these opportunities.
Improving the quality of gastric cancer surgery: factors associated with positive resection margins for gastrectomy
Authors: Zhao Junjie , Li Haojie , Fang Yong , Wang Xuefei , Sun Yihong 
Published: April 2022

Abstract
Purpose
Positive margins after gastrectomy have been associated with poor patient prognosis. This study aimed to identify risk factors associated with margin-positive resections.

Methods
The National Cancer Database was queried from 2004 to 2014 for all patients with gastric adenocarcinoma who underwent resection with curative intent and had known margin status. Univariable and multivariable logistic regression analysis was performed to identify variables associated with positive margins.

Results
A total of 32,193 patients were identified who met study inclusion criteria, of which 11.8% (3786 patients) had a margin-positive resection. Tumor size > 6 cm, T3 or T4 tumors, tumor location in the body of stomach or in multiple regions, signet ring cell histology, presence of lymphovascular invasion, positive lymph node involvement, and lack of neoadjuvant therapy were independently associated with an increased risk of positive margins.

Conclusions
Advanced disease characteristics, aggressive tumor pathology, and absence of neoadjuvant therapy were associated with margin-positive resections.
Avalanche Preparedness and Accident Analysis Among Backcountry Skier, Sidecountry, and Snowmobile Fatalities in the United States: 2009 to 2019
Authors: Niemann Danielle , Paul Subrata , Rahman Humairat H. 
Published: April 2022

Introduction While avalanche fatalities have remained relatively steady per year, data suggest a possible increase in sidecountry use and snowmobile fatalities. Limited information is known regarding the accident details and preparedness among different groups of backcountry users including snowmobiles, sidecountry, and backcountry skiers, and what specific factors could contribute to their fatalities. Methods Avalanche fatality reports covering all US states posted by the Colorado Avalanche Information Center available online for 10 seasons (2009–2010 through 2018–2019 seasons) were analyzed for group size, specific equipment carried, burial depth, burial time, and other details. Only reports in the 3 following categories were included in the analysis: backcountry ski/snowboard, sidecountry ski/snowboard, and snowmobile/snowbike. These aspects were compared among the 3 tourer types using statistical analyses (ANOVA). Results Two hundred and five fatalities were analyzed (n=32 sidecountry, n=91 skier/snowboard, n=82 snowmobile/snowbike). Using 2 preparedness scores, the ski/snowboard group had the greatest distribution of high scores when evaluated by equipment carried and group size, with significant differences per group ( P<0.01). Of the fatalities that were buried, burial time was related to the tourer group ( P=0.04), with the ski/snowboard group having the highest proportion of burials <15 min. Burial depth was significantly different among the 3 tourer groups, with snowmobiles buried the deepest on average ( P<0.01). Conclusions Despite limited data available on fatalities, an analysis of preparedness suggests that backcountry skiers and snowboarders are more prepared for avalanche accidents compared to snowmobiles and sidecountry users when evaluated by equipment carried and group size.
The Human Rights to Water and Sanitation
Authors: Heller Léo 
Published: April 2022

This analysis of the human rights to safe drinking water and sanitation (HRtWS) uncovers why some groups around the world are still excluded from these rights. Léo Heller, former United Nations Special Rapporteur on the human rights to water and sanitation, draws on his own research in nine countries and reviews the theoretical, legal, and political issues involved. The first part presents the origins of the HRtWS, their legal and normative meanings and the debates surrounding them. Part II discusses the drivers, mainly external to the water and sanitation sector, that shape public policies and explain why individuals and groups are included in or excluded from access to services. In Part III, public policies guided by the realization of HRtWS are addressed. Part IV highlights populations and spheres of living that have been particularly neglected in efforts to promote access to services.
Choosing Wisely: Canadian Neurological Society Recommendations for Advance Care Planning
Authors: McKenzie Erica D. , Couillard Philippe 
Published: April 2022

ABSTRACT:Advance care planning (ACP) is a process to understand and communicate one’s wishes, values, and preferences for future medical care. As part of the Choosing Wisely Canada “Time to Talk” initiative, the Canadian Neurological Society (CNS) endorsed the creation of a working group to propose ACP recommendations for patients with neurological illness. A narrative review of primary literature on ACP in neurological and non-neurological illness, medical society guidelines, and publications by patient advocacy groups was conducted. Eight ACP recommendations were deemed relevant and important to Canadian neurology practice and were approved by the CNS Board of Directors. The recommendations are meant to serve as guidance for Canadian neurologists, to stimulate discussion about ACP within the Canadian neurology community, and to encourage neurologists to engage in ACP conversations with their patients.
On the reproducibility of fully convolutional neural networks for modeling time–space-evolving physical systems
Authors: Pinto Wagner G. , Alguacil Antonio , Bauerheim Michaël 
Published: April 2022

Abstract
Reproducibility of a deep-learning fully convolutional neural network is evaluated by training several times the same network on identical conditions (database, hyperparameters, and hardware) with nondeterministic graphics processing unit operations. The network is trained to model three typical time–space-evolving physical systems in two dimensions: heat, Burgers’, and wave equations. The behavior of the networks is evaluated on both recursive and nonrecursive tasks. Significant changes in models’ properties (weights and feature fields) are observed. When tested on various benchmarks, these models systematically return estimations with a high level of deviation, especially for the recurrent analysis which strongly amplifies variability due to the nondeterminism. Trainings performed with double floating-point precision provide slightly better estimations and a significant reduction of the variability of both the network parameters and its testing error range.
Pension systems in south-eastern Europe: what worked and what did not
Authors: Casey Bernard H. 
Published: April 2022

AbstractMany south-east European states made the transition from socialist to market economies. All described here had to reform their pension systems to match the new context in which these operated. The experiences of 10 countries are reviewed – seven of which were once part of Yugoslavia. Some countries’ reforms were more radical than others. Five of them merely adapted the Bismarckian systems they had inherited; four others adopted the “three pillar” model that the World Bank had been propagating. One went further than that. The four who followed World Bank model were often forced to backtrack. Whatever the longer-term benefits, they generated their own shorter-term fiscal problems. Nonetheless, the most radical reformer gives some indications of possible ways forward. The south-eastern European states do not have financial markets that can support capitalised/funded pension systems. Nor do they have the resources to pay proportional pensions that, at the same time, keep retired people out of poverty. The article suggests that their governments should concentrate upon improving economic performance to satisfy longer term aspirations and on ensuring that pensioners are able to live properly if not luxuriously by using tax-financed transfer measures. Provision above this level can be secured through savings plans, but it must be accepted that the investments to secure those savings will have to be made abroad.
The acquisition of capabilities: How firms use dynamic and ordinary capabilities to manage uncertainty
Authors: Irwin Kris , Gilstrap Collin , Drnevich Paul , Sunny Manoj 
Published: April 2022

AbstractHow organizations utilize capabilities to achieve competitive advantage and improve performance has received an abundance of scholarly attention. Both ordinary and dynamic capabilities (DC) enable organizations to achieve higher performance when leveraged appropriately and under favorable conditions. The complexity of an organization's motives for why and how different capabilities are acquired drives us further to explore what complementarities organizations might achieve and under what contexts. Specifically, we explore how firms engaging in mergers and acquisitions (M&A) to acquire dynamic and/or ordinary capabilities experience different market reactions and levels of short- and long-run value creation given environmental uncertainty. Our results support the acquisition of ordinary capabilities for predicting positive short-term market reactions and of DC for longer-run firm performance post-M&A, with uncertainty factors moderating these relationships. We discuss both the theoretical and practical implications of uncertainty and acquisitions of these capabilities and offer suggestions for future research.
Asian monsoon and vegetation shift: evidence from the Siwalik succession of India

Published: April 2022

AbstractQuantitative Miocene climate and vegetation data from the Siwalik succession of western Nepal indicate that the development of the Indian summer monsoon has had an impact, though in part, on vegetation changes. The climate and vegetation of the Lower (middle Miocene) and Middle (late Miocene–Pliocene) Siwalik successions of Darjeeling, eastern Himalaya, have been quantified. Reconstructed climate data, using the Coexistence Approach, suggest a decrease in winter temperatures and precipitation during the wettest months (MPwet) from the Lower to Middle Siwalik. The floristic assemblage suggests that Lower Siwalik forests were dominated by wet evergreen taxa, whereas deciduous ones became more dominant during the Middle Siwalik. The vegetation shift in the eastern Himalayan Siwalik was most likely due to a decrease in MPwet. The quantified climate–vegetation data from the eastern and western Himalayan Siwalik indicate that changes in the Indian summer monsoon had a profound impact on vegetation development during the period of deposition. We suggest that the decrease in winter temperature and summer monsoon rainfall during the Middle Siwalik might be linked with the Northern Hemisphere glaciation/cooling or a number of other things that were also going on at the time, including the continued rise of the Himalaya, and drying across the Tibetan region, which may have affected atmospheric circulation regionally.

Published: April 2022

AbstractThis article focuses on designing and evaluating conversation practice in a second language (L2) with a robot that employs human spoken and non-verbal interaction strategies. Based on an analysis of previous work and semi-structured interviews with L2 learners and teachers, recommendations for robot-led conversation practice for adult learners at intermediate level are first defined, focused on language learning, on the social context, on the conversational structure and on verbal and visual aspects of the robot moderation. Guided by these recommendations, an experiment is set up, in which 12 pairs of L2 learners of Swedish interact with a robot in short social conversations. These robot–learner interactions are evaluated through post-session interviews with the learners, teachers’ ratings of the robot’s behaviour and analyses of the video-recorded conversations, resulting in a set of guidelines for robot-led conversation practice: (1) societal and personal topics increase the practice’s meaningfulness for learners; (2) strategies and methods for providing corrective feedback during conversation practice need to be explored further; (3) learners should be encouraged to support each other if the robot has difficulties adapting to their linguistic level; (4) the robot should establish a social relationship by contributing with its own story, remembering the participants’ input, and making use of non-verbal communication signals; and (5) improvements are required regarding naturalness and intelligibility of text-to-speech synthesis, in particular its speed, if it is to be used for conversations with L2 learners.
Rhabdomyolysis in Young Adult Male Stabilized on Mirtazapine and with History of COVID-19 Infection
Authors: Philippe Christine , Misquitta Douglas , Niedermier Julie 
Published: April 2022

AbstractStudy ObjectiveThe purpose of this case study is to review the clinical presentation and medical workup of a young adult male presenting with rhabdomyolysis in the setting of suspected contributing factors, including treatment with mirtazapine and history of COVID-19 infection.MethodThis case study involves a 19-year-old male in a residential setting with a psychiatric history of major depressive disorder and post-traumatic stress disorder who had been stabilized on mirtazapine for 9 months. Then, the patient exhibited fever, sore throat, cough, nausea, diarrhea, and malaise and was diagnosed with COVID-19 infection; he did not require hospitalization, was treated with supportive care, and signs and symptoms resolved uneventfully. Approximately 2 months later, in the winter, the patient presented for clinical assessment due to hematuria and painful urination. History revealed that he had been exercising excessively exercising over the past 24 hours, completing hundreds of push-ups and sit-ups. The patient presented to a nearby community hospital and was found to have creatine kinase of over 500,000. He was transferred to a large Midwestern university hospital for further evaluation and management.ResultsThe patient’s serum creatine kinase level was found to be 510,000 U/L. Patient’s ALT, AST, and alkaline phosphatase were 283, 79, and 76 IU/L, respectively, while creatinine was 0.92. Patient received vigorous hydration, supportive care, and further evaluation. Treatment with mirtazapine was discontinued. The following week he developed severe nausea and vomiting; creatine kinase had decreased to 920, while hepatic function tests remained mildly elevated. Evaluation for hepatitis, cytomegalovirus, and Epstein-Barr virus were negative, as was Wilson’s disease and hemochromatosis. Further medical workup for other potential causes of rhabdomyolysis was negative. The patient recovered and is asymptomatic with return to normal lab values. He remains in psychiatric follow-up.ConclusionsThe patient’s presentation of rhabdomyolysis may have been attributable to multiple factors. Independently, sustained excessive physical activity, COVID-19 infection, and treatment with mirtazapine have all been implicated in the development of rhabdomyolysis. Caution should be taken when prescribing mirtazapine in individuals at higher risk of developing rhabdomyolysis, including those engaged in excessive exercise or who have had COVID-19 infection.FundingNo funding

AbstractIntroductionDeutetrabenazine is FDA-approved for the treatment of tardive dyskinesia (TD) in adults. In two 12-week pivotal trials (ARM-TD/AIM-TD), deutetrabenazine significantly improved Abnormal Involuntary Movement Scale (AIMS) scores and was well-tolerated. This post hoc analysis examined the efficacy and safety of long-term deutetrabenazine treatment in TD patients with comorbid psychiatric illness, including schizophrenia/schizoaffective disorder and mood disorders (bipolar/depression/other).MethodsPatients who completed ARM-TD or AIM-TD enrolled in the 3-year, open-label extension (OLE) study. Deutetrabenazine was titrated based on dyskinesia control and tolerability. Change from baseline in total motor AIMS score, Patient Global Impression of Change (PGIC), Clinical Global Impression of Change (CGIC), and adverse events (AEs) were analyzed in subgroups by comorbid psychiatric illness.ResultsA total of 337 patients in the OLE study were included in the analysis: 205 patients with schizophrenia/schizoaffective disorder (mean age, 55 years; 50% male; 6.4 years since diagnosis; 92% taking DRA) and 131 patients with mood disorders (mean age, 60 years; 35% male; 4.6 years since diagnosis; 50% taking DRA). At week 145, mean ± SE dose was 40.4 ± 1.1 mg/day for schizophrenia/schizoaffective disorder (n = 88) and 38.5 ± 1.2 mg/day for mood disorders (n = 72). Mean ± SE change from baseline in AIMS score at week 145 was −6.3 ± 0.49 and −7.1 ± 0.58, 56% and 72% achieved PGIC treatment success, and 66% and 82% achieved CGIC treatment success in schizophrenia/schizoaffective disorder and mood disorder patients, respectively. Overall AE incidence (exposure-adjusted incidence rates [incidence/patient-years]) was low: any, 1.02 and 1.71; serious, 0.10 and 0.12; leading to discontinuation, 0.07 and 0.05).ConclusionLong-term deutetrabenazine treatment provided clinically meaningful improvements in TD-related movements, with a favorable safety profile, regardless of underlying comorbid psychiatric illness.FundingTeva Pharmaceutical Industries Ltd., Petach Tikva, Israel
Abstract meaning representation of Turkish
Authors: Oral Elif , Acar Ali , Eryiğit Gülşen 
Published: April 2022

AbstractAbstract meaning representation (AMR) is a graph-based sentence-level meaning representation that has become highly popular in recent years. AMR is a knowledge-based meaning representation heavily relying on frame semantics for linking predicate frames and entity knowledge bases such as DBpedia for linking named entity concepts. Although it is originally designed for English, its adaptation to non-English languages is possible by defining language-specific divergences and representations. This article introduces the first AMR representation framework for Turkish, which poses diverse challenges for AMR due to its typological differences compared to English; agglutinative, free constituent order, morphologically highly rich resulting in fewer word surface forms in sentences. The introduced solutions to these peculiarities are expected to guide the studies for other similar languages and speed up the construction of a cross-lingual universal AMR framework. Besides this main contribution, the article also presents the construction of the first AMR corpus of 700 sentences, the first AMR parser (i.e., a tree-to-graph rule-based AMR parser) used for semi-automatic annotation, and the evaluation of the introduced resources for Turkish.
The league against imperialism, national liberation, and the economic question
Authors: Jani Disha Karnad 
Published: April 2022

AbstractThe League Against Imperialism (LAI) was an international organization active from 1927 to 1937 that brought together communists, socialists, nationalists, trade unionists, and pacifists in order to coordinate their myriad ‘assaults against empire’. Founded with the support of the Communist International, the LAI at its peak had a membership of several hundred people, from every inhabited continent, among them prominent interwar activists and future heads of state. The organization aspired both to become an international movement and to coordinate specific instances of mass struggle. Exploring both aspects shows how the LAI interwove the global and the local in interwar anti-imperialist movements. This article draws from recent work on interwar anti-imperialism and internationalism as well as work on struggles for economic sovereignty in the 1960s–70s to argue that a critical aspect of the LAI’s anti-imperial politics concerned the relationship between political independence and the world economy. Through an examination of LAI members’ writings and public addresses, we can observe this relationship through the staging of their own claims for self-rule and control over land, labour, and resources.
