A gamified approach to assessing mental rotation in virtual reality
Authors: Bartlett Kristin Alicia , Palacios-Ibáñez Almudena , Camba Jorge Dorribo 
Published: May 2024

AbstractWe present a new spatial skills assessment tool, the Virtual Reality Mental Rotation Assessment. Results suggest that the gamified immersive experience enabled increased levels of engagement and motivation and the instrument was likely not biased in favor or people with past virtual reality (VR) experience. Using VR did not appear to introduce additional problems beyond those present in a traditional spatial test, as moving one's body to change perspective did not correlate with improved performance. Our findings have implications for training and assessing spatial skills in engineering.
VR headset vs. PC screen as virtual learning tour interface for Chinese architecture heritage investigation
Authors: Chen Yuetong , Hua Min 
Published: May 2024

AbstractIn design education, integrating digital tools has revolutionized pedagogical approaches. This study examines the impact of VR HMDs and PC screens on learning ancient Chinese architecture using a virtual tour. Involving 22 students, it assessed simulator sickness, user experience, and spatial awareness. Results show VR had a more positive spatial learning experience but the same learning outcomes. VR enhances presence but increases simulator sickness. The study underscores VR's potential and limitations in ancient Chinese architectural education, suggesting future research directions.
Conceptualization of an artificial intelligence-assisted tutoring system for teaching technical drawing skills to undergraduate students
Authors: Fastabend Jonas , Müller Benedikt , Roth Daniel , Kreimeyer Matthias 
Published: May 2024

AbstractIn design education, technical drawing training requires a large amount of resources. The aim of this paper is to propose a concept for an artificial intelligence-based tutoring system that partly automates technical drawing education. The educational needs of the students are defined via an error analysis of 100 corrected drawing exercises and the definition of 3 error clusters with 134 different error types. Three sub-concepts with a collection of training exercises are proposed for the tutoring system to mitigate these errors. The resulting concept is validated by a survey with 29 students.

Developing a method to improve unknown identification and design efforts for environmental transition: a case study in the packaging industry
Authors: Deshoulières Marion , Le Masson Pascal , Weil Benoît 
Published: May 2024

AbstractMost manufacturing companies have tested and adopted sustainable design methods to navigate their product's environmental transition. While successful at first in enhancing their environmental performance, these companies later struggle to pursue their environmental transition. This entails mastering two critical competencies: identifying transition unknowns, and fostering adequate design efforts. This action research with an innovative design intermediary - which has completed four sustainable packaging missions - reveals the specific design barriers encountered for environmental transition.
What can we learn from outstanding designers? The relationship between design expertise and prototyping
Authors: Jobst Birgit , Thoring Katja , Badke-Schaub Petra 
Published: May 2024

AbstractThis paper contributes with insights regarding design expertise and prototyping. Seven high performers – Outstanding Designers – were interviewed to learn about their prototyping activities. The Outstanding Designers emphasised prototyping for reflection, gaining certainty, and cooperating with clients. They expressed a strong attachment regarding the use of prototyping that results in specific routines. We call this behaviour the Outstanding Designers’ bonding with prototyping. The main insights were synthesised into a model outlining the relation between design expertise and prototyping.
Design methodology for optimal sensor placement for cure monitoring and load detection of sensor-integrated, gentelligent composite parts
Authors: Meyer zu Westerhausen Sören , Kyriazis Alexander , Hühne Christian , Lachmayer Roland 
Published: May 2024

AbstractSelecting right positions for composite-integrated sensors for monitoring cure during manufacturing and loads during product use presents challenges for engineering design. Since an optimal sensor placement (OSP) methodology for both phases is not emphasised enough in literature, a new methodology is proposed. This methodology is based on a Genetic Algorithm and strain gauges, temperature sensors and interdigitated electrode sensors for cure monitoring and physics-informed neural network-based load detection. Additionally, it includes sensor node positions optimization in a sensor network.

Published: May 2024

AbstractA volatile environment and an increasing number of products along with a growing range of functions pose a challenge for companies when it comes to further development. Existing methods are no longer sufficient to cope with these challenges. In order to develop new methods, the process and challenges in the advancement of product portfolios must be understood. In this paper we conduct an interview study with ten experts to gain a better understanding of the advancement of product portfolios. Triggers, changes and actions are examined and goals and requirements for new methods are derived.
Evaluation of the methodical framework for the management of uncertainty in the context of the integration of sensory functions
Authors: Welzbacher Peter , Witt Sawa Vinzenz , Koch Yanik , Kirchner Eckhard 
Published: May 2024

AbstractAs digitalization progresses, the development and integration of sensory functions in technical systems become increasingly important. Managing uncertainty, especially in the early phase of this process, is crucial to ensure the reliability of the data provided. Therefore, a methodical framework for the identification, analysis and consideration of uncertainty was presented in prior works. In this contribution, the effectivity of the framework is evaluated by applying it to a sensory function for rotational speed and offset measurement of a disk pack coupling using sensor integrating bolts.

VARIABILITY OF RADIOCARBON RESERVOIR AGE EFFECTS IN LAKES AND RIVERS IN ANATOLIA AND LESSER CAUCASUS
Authors: Fontugne Michel , Hatté Christine , Tisnérat-Laborde Nadine , Ollivier Vincent , Kuzucuoğlu Catherine 
Published: May 2024

ABSTRACTMultiproxy sedimentary sequence analysis constitutes the basis for reconstructions of past paleoenvironments and climate evolution. These sequences are, for the most part, obtained by coring in lakes, maars or crater lakes whose waters can record volcanic activity or karstic contributions, especially in Eastern Anatolia and the Lesser Caucasus. The reservoir age effect in these geological contexts leads to an apparent aging of the radiocarbon ages which also affects the plants and animals developing in or near these waters and consequently the population consuming them. We present here some results obtained from modern samples taken from Mediterranean, central and eastern Anatolian lakes, from the Van and Sevan lakes and along the Kura River and its tributaries from the Lesser Caucasus. The effect of volcanic CO2 outgassing in the vicinity of maar crater lakes is also discussed.

ABSTRACTThe absorption and distribution of radiocarbon-labeled urea at the ultratrace level were investigated with a 14C-AMS biotracer method. The radiopharmaceutical concentrations in the plasma, heart, liver, spleen, lung, kidney, stomach, brain, bladder, muscle, testis, and fat of rats after oral administration of 14C urea at ultratrace doses were determined by AMS, and the concentration-time curves in plasma and tissues and pharmacokinetic distribution data were obtained. This study provides an analytical method for the pharmacokinetic parameters and tissue distribution of exogenous urea in rats at ultratrace doses and explores the feasibility of evaluation and long-term tracking of ultratrace doses of drugs with AMS.

Published: May 2024

ABSTRACTThis paper compares various wood pretreatment methods for highly degraded, and problematic fossil wood extracted from the opencast Szczerców site of the Bełchatów Lignite Mine in Central Poland. The study evaluates the pretreatment methods using both large samples (55–255 g, referred to as series A) and small samples (36–150 mg, referred to as series B). Additionally, all preparation methods were applied to medium-sized samples (approximately 3 g, referred to as series C) with solvent washes in the Soxhlet apparatus. Radiocarbon dating was conducted using the LSC technique (subseries A1) and the AMS technique (subseries A2, series B, and C). The effectiveness and utility of each pretreatment protocol were compared based on 14C measurements and FTIR analysis. Through the conducted research and a multi-criteria analysis, the most effective method for preparing old fossil wood was identified. Our experience indicates that an extended, multistage preparation of highly degraded fossil wood samples, with a 14C concentration near the detection limit of the radiocarbon method, may result in a significant increase in 14C content.
Determination of radiocarbon content in liquid fuel blends by accelerator mass spectrometry and liquid scintillation counting in the Gliwice radiocarbon and mass spectrometry laboratory
Authors: Baranyika Jean Baptiste , Piotrowska Natalia , Michczyński Adam 
Published: May 2024

AbstractThe increase in biobased material usage requires the methods of verification to investigate the actual content of biocarbon in such materials, including liquid fuels. The determination of biocarbon in liquid samples using 14C required adaptation of existing sample preparation methods. In this study, both accelerator mass spectrometry (AMS) and liquid scintillation counting (LSC) methods were used to determine the content of 14C in six different liquid fuel blends produced from purely bio-based hydrotreated vegetable oil (HVO) and a 14C-free petrodiesel sample (ON/UF-BC). The results obtained for pure petrodiesel provide background values. The results indicate a good agreement between LSC and AMS, and a linear correlation between the 14C measurement results for blended samples and HVO content affirmed the reproducibility between the two methods. The repeatability of AMS results was tested on 10 aliquots of one of the blends, and the results were deemed reproducible.

Published: May 2024

AbstractA healthy diet is at the forefront of measures to prevent type 2 diabetes. Certain vegetable and fish oils, such as pine nut oil (PNO), have been demonstrated to ameliorate the adverse metabolic effects of a high-fat diet. The present study investigates the involvement of the free fatty acid receptors 1 (FFAR1) and 4 (FFAR4) in the chronic activity of hydrolysed PNO (hPNO) on high-fat diet-induced obesity and insulin resistance. Male C57BL/6J wild-type, FFAR1 knockout (-/-) and FFAR4-/- mice were placed on 60 % high-fat diet for 3 months. Mice were then dosed hPNO for 24 d, during which time body composition, energy intake and expenditure, glucose tolerance and fasting plasma insulin, leptin and adiponectin were measured. hPNO improved glucose tolerance and decreased plasma insulin in the wild-type and FFAR1-/- mice, but not the FFAR4-/- mice. hPNO also decreased high-fat diet-induced body weight gain and fat mass, whilst increasing energy expenditure and plasma adiponectin. None of these effects on energy balance were statistically significant in FFAR4-/- mice, but it was not shown that they were significantly less than in wild-type mice. In conclusion, chronic hPNO supplementation reduces the metabolically detrimental effects of high-fat diet on obesity and insulin resistance in a manner that is dependent on the presence of FFAR4.

AbstractObjectiveThe purpose of this study is to analyse the effect of half canal wall down tympanomastoidectomy in the treatment of chronic otitis media or cholesteatoma.MethodIn this retrospective study, the half canal wall down tympanomastoidectomy technique was used at our hospital for chronic otitis media or cholesteatoma removal in 265 adult patients, representing 271 operated ears, with an average follow-up time of 8.4 years.ResultsThe post-operative cavities were slightly wider and straighter in 91.9 per cent of the ears. Fifteen per cent of the patients needed cavity cleaning every six months, 25 per cent of them needed cavity cleaning every year and 60 per cent of the patients had a self-cleaning cavity. Only one patient with a cleft palate experienced cholesteatoma recurrence in the mesotympanum.ConclusionThe half canal wall down tympanomastoidectomy technique showed a low-recurrence rate and satisfying operative cavities. The half canal wall down tympanomastoidectomy technique is a good choice for middle ear surgery.

AbstractObjectiveThis observational study investigates migratory foreign bodies in the upper aerodigestive tract, emphasising clinical presentation, assessment and factors contributing to extraluminal migration.MethodsConducted across multiple medical centres in India, the study included 15 patients aged 11 to 70 years. Detailed observations, demographic information, clinical history, radiological findings and intra-operative outcomes were compiled.ResultsFifteen patients presented with varied symptoms. Fish and chicken bones, along with metal wires, were common foreign bodies. Computed tomography scans played a crucial role in diagnosis, confirming extraluminal migration. Neck exploration successfully retrieved foreign bodies in most cases, with varied sites of impaction.ConclusionMigratory foreign bodies, although rare, pose significant challenges for otolaryngologists. Early recognition, thorough diagnosis and meticulous neck exploration, is crucial for effective management, preventing severe complications. This study adds valuable insights to the understanding of migratory foreign bodies, contributing to the existing literature in otolaryngology practice.
Opaque morphology and phonology: Historical prefixes in English
Authors: Dabouis Quentin , Fournier Jean-Michel 
Published: May 2024

Abstract
In most of the literature on English phonology, historically prefixed words such as contain, respect or submit are seen as having no morphological structure synchronically. However, such words were treated as complex in the early generative literature and are still analysed in that way in part of the literature. In this paper, we seek to review the evidence for the claim that such words are simplex words, which predicts that they should pattern with words with no internal structure in their phonological and morphological behaviours and in psycholinguistic experiments. We show that the evidence does not support that claim and shows that these words should be treated as morphologically complex units, although they differ from words with productive morphology. As these words tend to be partly or entirely opaque semantically, this raises the question of how such structures may be learned. We argue that the recurrence of forms is the main factor leading to their identification and lay out a possible order of acquisition of various morphological structures. Finally, we argue that theories of phonology may account for this by allowing the reference to morphological constituents whose semantics are impoverished.
The performance of machine aesthetics: acoustic reimagining of electronic music
Authors: Stevenson Alex 
Published: May 2024

AbstractThis article explores the emergence of musical performance practices whereby electronic music styles, along with the musical and sonic characteristics inherent in their electronic production, are emulated through live musical performance using acoustic instrumentation. The article draws on Brummett's (1999) concept of ‘machine aesthetics’ to explore the emergence of these practices, whereby musicians emulate sonic and musical attributes of music usually produced by machines, without the use of machines. Utilising semi-structured interviews and musical analysis of records by Abstract Orchestra and GoGo Penguin, the article attempts to contextualise these practices within their broader function in popular music production and performance.
Rethinking peer influence and risk taking: A strengths-based approach to adolescence in a new era
Authors: Allen Joseph P. 
Published: May 2024

AbstractThe ways that psychopathology manifests in adolescence have shifted dramatically over the past twenty-five years, with rates of many externalizing behaviors declining substantially while rates of anxiety and depressive disorders have skyrocketed. This paper argues that understanding these changes requires rethinking the field’s historically somewhat negative views of intense peer connections, peer influences, and adolescent risk-taking behavior. It is argued that intense peer connections are critical to development, and that peer influence and risk taking have important, often overlooked, adaptive components. The shift in observed manifestations of adolescent psychopathology over this period can be viewed at least partly in terms of a shift away from strong peer connections and toward greater risk aversion. Implications for research and intervention based on a focus on the adaptive aspects of peer influences and risk taking are discussed.
Mitochondrial cardiomyopathy: a puzzle for the final diagnosis
Authors: Constante Andreia Duarte , Abreu Susana Martins , Trigo Conceição 
Published: May 2024

AbstractHypertrophic cardiomyopathy in children has diverse causes. Mitochondrial diseases, a rare aetiology leading to cardiomyopathy in 20–40% of affected children, predominantly present as hypertrophic cardiomyopathy. Diagnosis is challenging due to inconsistent genotype-phenotype correlation, resulting in various clinical presentations. We present a case of a one-month-old infant with severe hypertrophic cardiomyopathy and cardiac tamponade. Genetic diagnosis revealed a Valyl-tRNA synthetase 2 (VARS2) gene mutation, linking it to mitochondrial encephalopathy-cardiomyopathy. This case highlights novel variants and expands the understanding of hypertrophic cardiomyopathy aetiology in infants.
