Chambolle–Pock’s Primal-Dual Method with Mismatched Adjoint
Authors: Lorenz Dirk A. , Schneppe Felix 
Published: January 2023

AbstractThe primal-dual method of Chambolle and Pock is a widely used algorithm to solve various optimization problems written as convex-concave saddle point problems. Each update step involves the application of both the forward linear operator and its adjoint. However, in practical applications like computerized tomography, it is often computationally favourable to replace the adjoint operator by a computationally more efficient approximation. This leads to an adjoint mismatch in the algorithm. In this paper, we analyze the convergence of Chambolle–Pock’s primal-dual method under the presence of a mismatched adjoint in the strongly convex setting. We present an upper bound on the error of the primal solution and derive stepsizes and mild conditions under which convergence to a fixed point is still guaranteed. Furthermore we show linear convergence similar to the result of Chambolle–Pock’s primal-dual method without the adjoint mismatch. Moreover, we illustrate our results both for an academic and a real-world inspired application.
Hu-bot: promoting the cooperation between humans and mobile robots
Authors: Miras Karine , Mocanu Decebal , Eiben A. E. 
Published: January 2023

AbstractThis paper investigates human–robot collaboration in a novel setup: a human helps a mobile robot that can move and navigate freely in an environment. Specifically, the human helps by remotely taking over control during the learning of a task. The task is to find and collect several items in a walled arena, and Reinforcement Learning is used to seek a suitable controller. If the human observes undesired robot behavior, they can directly issue commands for the wheels through a game joystick. Experiments in a simulator showed that human assistance improved robot behavior efficacy by 30% and efficiency by 12%. The best policies were also tested in real life, using physical robots. Hardware experiments showed no significant difference concerning the simulations, providing empirical validation of our approach in practice.
Online reading lists: a mixed-method analysis of the academic perspective
Authors: Kumara P. P. N. V. , Hinze Annika , Vanderschantz Nicholas , Timpany Claire 
Published: January 2023

AbstractReading list systems are widely used in tertiary education as a pedagogical tool and for tracking copyrighted material. This article explores the make-up of reading lists across a whole university. We investigated the experience of academics and librarians when creating reading lists. A mixed-method approach was employed in which we performed a transaction log analysis on reading lists at a single university, from 2016 to 2020. A questionnaire was then answered by both academics and academic liaison librarians about their experience with reading lists. The results of our analysis found that uptake of reading lists varies widely between different academic disciplines. Academic engagement with reading lists was found to show only incremental growth over time, and overall satisfaction by academics with the reading list system was low. We explore implications for reading lists implemented through digital Libraries and recommend developing discipline-specific support to increase reading list numbers and to integrate pedagogical features to increase academic buy-in.
The Underlying Mechanisms in the Association Between Traumatic Brain Injury in Childhood and Conduct Disorder Symptoms in Late Adolescence
Authors: Khalaf Hanan K S. , Martin Alex F. , De Brito Stephane A. , Barker Edward D. 
Published: January 2023

AbstractThe present study examined i) the direct association between traumatic brain injury (TBI) in childhood and conduct disorder symptoms in adolescence, ii) whether this effect is mediated by impulsivity and/or callous unemotional traits (CU traits), and iii) whether these indirect effects are moderated by childhood family adversity and adolescent substance use. Utilising data from the Avon Longitudinal Study of Parents and Children (ALSPAC), participants with head injury information up to 12 years (4.5 years, 5.4 years, 6.5 years, 8.6 years, 11.7 years) were identified and categorised into a TBI (n = 409), orthopaedic injury (n = 1469) or non-injury group (n = 5685). Psychosocial factors such as impulsivity at 13 years, CU traits at 13 years, childhood family adversity (between birth to 4 years) and substance use at 14 years were collated for moderated mediation analyses. Conduct disorder symptoms were assessed at 16 years of age. TBI and conduct disorder symptoms were positively associated, and this association was mediated by impulsivity but not CU traits. The indirect effects were higher in magnitude for individuals with higher levels of childhood family adversity. Adolescent substance use was not found to moderate the indirect effects between TBI and conduct disorder symptoms. These results were specific to TBI individuals, and not in participants with orthopaedic injury and no reported injuries. Targeting impulsivity and early family adversity may alleviate the risk of conduct disorder symptoms following TBI in childhood. These findings have important implications for informing neuro-rehabilitative and preventative measures in clinical and community settings.

Published: January 2023

AbstractPurpose: The aim was to investigate the feasibility and optimal stimulation parameters for supramaximal stimulation of muscle recorded transcranial electrical stimulation motor evoked potentials (mTc-MEP). Methods: Forty-seven consecutive patients that underwent scoliosis surgery were included. First, the feasibility of supramaximal stimulation was assessed for two settings (setting 1: pulse duration 0.075ms, interstimulus interval (ISI) 1.5ms; setting 2: pulse duration 0.300ms, ISI 3ms). Thereafter, three mTc-MEP parameters were considered for both settings; (1) elicitability, (2) amplitude, and (3) if supramaximal stimulation was achieved with ≥ 20 V below maximum output. Finally, ISIs (1ms–4ms) were optimized for setting 1. Results: Nine patients (19.15%) were excluded. Of the remaining patients, supramaximal stimulation was achieved in all patients for setting 1, and in 26 (68.42%) for setting 2. In one patient, mTc-MEPs were elicitable in more muscles for setting (1) Amplitudes were not significantly different. Stimulation voltage could be increased ≥ 20 V in all 38 patients for setting 1 and in 10 (38.46%) for setting (2) Optimal ISI’s differed widely. Conclusion: We recommend using setting 1 when monitoring mTc-MEPs with supramaximal stimulation, after which an individualized ISI optimization can be performed. Moreover, when using supramaximal stimulation, short ISI’s (i.e. 1ms or 1.5ms) can be the optimal ISI for obtaining the highest mTc-MEP amplitude.
The diagnosis and management of pheochromocytoma and paraganglioma during pregnancy
Authors: Clifton-Bligh Roderick J. 
Published: January 2023

AbstractDiagnosis of pheochromocytoma or paraganglioma (PPGL) in pregnancy has been associated historically with high rates of materno-fetal morbidity and mortality. Recent evidence suggests outcomes are improved by recognition of PPGL before or during pregnancy and appropriate medical management with alpha-blockade. Whether antepartum surgery (before the third trimester) is required remains controversial and open to case-based merits. Women with PPGL in pregnancy are more commonly delivered by Caesarean section, although vaginal delivery appears to be safe in selected cases. At least some PPGLs express the luteinizing hormone/chorionic gonadotropin receptor (LHCGR) which may explain their dramatic manifestation in pregnancy. PPGLs in pregnancy are often associated with heritable syndromes, and genetic counselling and testing should be offered routinely in this setting. Since optimal outcomes are only achieved by early recognition of PPGL in (or ideally before) pregnancy, it is incumbent for clinicians to be aware of this diagnosis in a pregnant woman with hypertension occurring before 20 weeks’ gestation, and acute and/or refractory hypertension particularly if paroxysmal and accompanied by sweating, palpitations and/or headaches. All women with a past history of PPGL and/or heritable PPGL syndrome should be carefully assessed for the presence of residual or recurrent disease before considering pregnancy.
Concept for a generic modular software architecture for the integration of quality relevant data and sample implementation for a laser sintering system
Authors: Michalkowski Carissa , Janhsen Jan , Springer Patrick 
Published: January 2023

AbstractAdditive manufacturing (AM) processes, such as laser sintering (LS), are complex in parameter dependencies and process flow. To be able to analyse and potentially predict the quality of the manufactured parts, the monitoring of multiple process parameters along the process chain is necessary. Currently, there are standards defined for data exchange but there is no framework to store and analyse these data or enhance a system with additional sensors. Therefore, a generic software concept is required that allows a consistent process monitoring. In this publication, a generic workflow for AM including pre- and post-processing steps is presented and relevant communication interfaces as e.g. OPC-UA, and relevant data types to be collected are identified. The concept allows the use of different communication protocols, storing and evaluating process data and by its modularity the enhancement of a system with its hardware. The stored values can be analysed by further scripts. The architecture is applicated on LS and partial aspects are prototypically implemented as well as practically validated. Therefore, a generic modular software concept, based on a hardware independent Docker based architecture, is presented. A practical feasibility test shows that machine and image data can be decentralized tapped and recorded, cloud-based analysed and web-based visualized.

Abstract

Purpose

Back-n is a white neutron beamline at China spallation neutron source, which was established in the year of 2018. It is a powerful facility for nuclear data measurement, neutron detector calibration, and radiation effect research.

Method

A series of detectors were built for different experiments, including beam monitoring, beam profile measurement, neutron induced secondaries (fission fragments, light charged particles and gamma) cross section measurement, and neutron resonance radiography, etc. A common digitization electronics and a cluster-based DAQ were developed for these detector systems. Most detectors have been employed at Back-n and serviced for experiments from the beginning of the beamline running.

Results and conclusion

As an overview of detectors of Back-n, the details of the detector design and the experiment performing are described in this paper. Some developing systems, e.g., MTPC and B-MCP, are also included.
Study on gasification dephosphorization of phosphorus magnetite reduced by SiC
Authors: Luo Guo-Ping , Hao Shuai , He Teng , Zhang Jing , Ji Xiang-Hui 
Published: January 2023

AbstractThe mechanism of reduction and dephosphorization of phosphorus-containing magnetite was studied using SiC as reducing agent. The thermodynamic conditions for the reduction of Ca3(PO4)2 and Fe3O4 by SiC were simulated by FactSage7.1 thermodynamics software, respectively, indicating that the reduction of Ca3(PO4)2 by SiC is thermodynamically feasible, but the kinetic conditions of the system are not good when no liquid phase is formed. The Fe2SiO4 liquid phase can be formed by reducing Fe3O4 by SiC at 1200 ℃. When the SiC ratio is 10 wt.%, the liquid phase content is the largest, which can reach more than 60 wt.%. Therefore, in this paper, the Fe2SiO4 liquid phase generated by the reduction of Fe3O4 by SiC is used to improve the kinetic conditions of the reduction of Ca3(PO4)2 by SiC at high temperature, and relevant experiments were carried out. The research results show that the system generates a suitable amount of liquid phase at 1250 °C, and the gasification dephosphorization rate is the highest, which is 39.89 wt.%, at 1200 °C, the reduction reaction was not fully carried out, and the dephosphorization rate by gasification was only 23.79 wt.%. At 1300 °C, Fe3O4 was completely reduced to metallic Fe, which combined with the reduced P4 gas to form Fe2P. Gasification dephosphorization rate is only 28.25 wt.%.
Religion and Hate Crime Victimisation: A Representative Study of Young People in Finland
Authors: Litvak Sophie , Kivivuori Janne , Kaakinen Markus 
Published: January 2023

AbstractKey societal macro-trends, such as immigration and the increasing salience of post-secular and identity-based religiosity, are converging to increase the relevance of religion in everyday life. Such developments call for a reassessment of the religion–victimisation link. We analyse the prevalence and severity patterns of hate victimisation in different groups defined by religion and explore the links between routine activities and lifestyle factors in hate crime victimisation. Our research site, Finland, is a country with a long history of religious homogeneity, recently interrupted by religious pluralisation. We draw on the 2020 sweep of the Finnish Self-Report Delinquency Study (FSRD), a nationally representative crime survey targeting 15–16-year-olds (N = 5482). We found that religiously unaffiliated and Muslim youths have an above-average risk of hate crime victimisation. There were some indications that the patterns of victimisation are different across religious denominations. For instance, Muslim youths were more likely to be attacked by adults. Hate crime victimisation risk was not mediated by routines and lifestyles. Independent of religion, there was, however, a strong and direct positive association between hate victimisation and a risky lifestyle, i.e. substance use and interaction with delinquent peers. Comparing the findings with assault victimisation, we observed that the results are largely specific to hate crime offending rather than assault victimisation in general. We discuss the findings from the perspective of criminological theory, future research needs, and policy implications.
Comprehensive exploration of spatial planning in Zhejiang Province
Authors: Chen Yong , Zhou Jun , Qian Jiawei 
Published: January 2023

AbstractZhejiang Province has been committed to the planning reform since the mid-1990s to adapt to economic and social transformation, urbanization and reform of administration system. The province has explored such comprehensive planning as urban system planning, integrated urban-rural planning, overall planning of county/city administrative area, and “multi-plan integration” planning in tandem. The efforts of Zhejiang have become one of the critical sources for developing our territorial spatial planning system after the government institutional reform. In the current practices of territorial spatial planning, Zhejiang has pursued further innovative exploration on optimizing urban-rural pattern, improving spatial quality, promoting spatial management and control, strengthening cross-border coordination, and developing intelligent planning in light of its foundations. By reviewing the history of Zhejiang’s comprehensive planning, the paper summarizes the overall development trend and related experiences in planning to provide insights and topics for further discussion for our current across-the-board territorial spatial planning.
PARADIGMS IN CRISIS: THE COVA DE MARCÓ (TIVISSA, TARRAGONA, CATALONIA) AND THE COEXISTENCE OF INCINERATION AND INHUMATION FUNERARY PRACTICES IN THE NORTHEASTERN IBERIAN PENINSULA DURING THE LATE BRONZE AGE
Authors: Vergès Josep Maria , Sardà Samuel , Diloli Jordi 
Published: January 2023

ABSTRACTParadigms such as the coexistence of incineration and inhumation funerary practices in the northeast of the Iberian Peninsula during the Late Bronze Age are supported by the association of human remains with elements of material culture as guiding fossils. One example is the association established by Salvador Vilaseca in 1939 between the human remains and grooved pottery discovered in the Cova de Marcó in Tivissa (Ribera d’Ebre, Catalonia). This association has been accepted until today and even become a paradigm for the mixing of autochthonism (inhumation rites) with the introduction of material novelties such as grooved pottery and incineration rites during the first period of the Late Bronze Age. Direct radiocarbon (14C) dating of human remains from the Cova de Marcó shows that the remains originate from the Chalcolithic period. This indicates that there is no relationship between the sepulchral episode and the grooved pottery associated with it and used to date it. This disputes the paradigm regarding the coexistence of these two funerary practices during the Late Bronze Age and invites scholars to conduct a critical review using absolute dating techniques directly on the human remains of similar cases in order to verify or disprove the paradigm’s validity.

AbstractA 5-week feeding trial was conducted in the cleaner fish Ballan wrasse (Labrus bergylta) for a better understanding of the basic biology of the intestinal functions and health in this stomach less species. During the trial, Ballan wrasse was fed either a reference diet, the reference diet supplemented with (i) a commercial prebiotic (Aquate™ SG, 0·4 %) expected to have beneficial effects, (ii) soya saponins (0·7 %) expected to induce inflammation or (iii) a combination of the prebiotics and the soya saponins to find a remedy for gut inflammation. Blood, intestinal tissue and gut content from four consecutive intestinal segments (IN1 – IN4) were collected. No significant differences in fish growth were observed between the four dietary groups. Saponin supplementation, both alone and in combination with prebiotics, increased weight index of IN2 and IN3 and decreased blood plasma glucose, cholesterol and total protein. Dry matter of intestinal content and activity of digestive enzymes were not affected by diet. Histomorphological analyses revealed a progressing inflammation with increased infiltration by immune cells particularly into the distal parts of the intestine in fish fed diets with saponins, both alone and in combination with prebiotics. Gene expression profiles obtained by RNA sequencing and quantitative PCR mirrored the histological and biochemical changes induced by the saponin load. The study demonstrated that Ballan wrasse gut health and digestive function may be markedly affected by feed ingredients containing antinutrients.
Polypropylene microplastics affect the physiology in Drosophila model
Authors: Tang Hao , Zhong Lichao , Xu Yifan , Jin Zhishen , Pan Zhihao , Shen Jie 
Published: January 2023

AbstractMicroplastics (MPs) pollution has been a hot research topic in recent years. MPs are ubiquitous throughout the ecological environment and are eventually accumulated in organisms through inhalation or ingestion. However, given that MPs are inert pollutants, their effects on organisms are not clear. In previous study, we have investigated the effects of polyethylene terephthalate MPs on physiology of Drosophila. What is the effect of polypropylene microplastics (PP-MPs)? The results of our experiments show that being exposed to high concentration of PP-MPs have significant effect on Drosophila. PP-MPs exposure can significantly increase locomotor activity and shorten the time of group sleep in Drosophila. In the presence of high concentrations of PP-MPs, the triglyceride content was reduced in females and their ability of egg production was affected. However, there was no significant effect on the level of protein and carbohydrate, or on the food intake. Our experimental results can provide some preliminary data for assessing the potential hazard of PP-MPs to other organisms.
Telephone versus face-to-face clinics for the management of new rhinology referrals: a retrospective cohort study
Authors: Metcalfe C , Mughal Z , Beech T 
Published: January 2023

AbstractObjectiveThis study aimed to compare outcomes of telephone and face-to-face consultations for new rhinology referrals and discuss the wider use of telemedicine in rhinology.MethodThis was a retrospective cohort study of new rhinology referrals seen in either a telephone or face-to-face clinic. Primary outcome was the proportion of patients given a definitive outcome at initial appointment (discharged or added to waiting list) versus those requiring follow up.ResultsA total of 137 patients (70 telephone, 67 face-to-face) were included. A total of 45 of 67 patients (67 per cent) undergoing a face-to-face consultation received a definitive outcome following initial review, versus 11 of 70 (16 per cent) telephone patients. Of 70 telephone patients 57 (81 per cent) were followed up face-to-face for examination.ConclusionThe role of telephone clinics in the assessment of new rhinology referrals is currently limited by the lack of clinical examination. Further research on developing remote assessment pathways that incorporate asynchronous review of recorded examinations are needed before telemedicine can become established within the rhinology clinic.
