Creating a Virtual Shadow of the Manufacturing of Automotive Components
Authors: Barlo A , Aeddula O , Chezan A R , Pilthammar J , Sigvant M 
Published: May 2024

Abstract
Within the automotive industry, there is an increasing demand for a paradigm shift in terms of which materials are used for the manufacturing of the automotive body. Global climate goals are forcing a rapid adaption of new, advanced, sustainable material grades such as the fossil free steels and materials containing higher scrap content. With the introduction of these new and untested materials, methods for accounting for variation in material properties are needed directly in the press lines.
The following study will focus on creating an initial virtual shadow of the manufacturing of a Volvo XC90 inner door panel through the application of Artificial Neural Networks (ANN). The virtual shadow differs from the concept of the digital twin by only being a virtual representation of the production line, with training data generated exclusively by numerical simulations, and having no automated communication with the physical press line control system. The virtual shadow can be used as an assistance to the press line operators to see how different press line settings and material parameter variations will impact the quality of the stamped component. The study aims to validate the virtual shadow through accurate predictions of the material draw-in measured in the physical press line.
Development of a digital material shadow for the press hardening route of medium manganese steel
Authors: Tilly Karl J. , Idzik Christian , Bailly David 
Published: May 2024

Abstract
Press-hardened ultra-high strength steel parts are widely used in the automotive sector for their lightweight and safety advantages. Medium-Manganese Steels (MMnS) are being explored as an alternative to boron-manganese steels due to their high strength and ductility after quenching, achieved at lower annealing temperatures thus reducing energy usage and carbon emissions. However, industrial adoption of MMnS is hindered by challenging processing requirements, e.g. in cold-rolling and press hardening.
To expedite and improve the process development, data-driven decisions based on process parameters hold promise. Establishing a link between process data and the final produced part necessitates the development of a framework for a Digital Material Shadow (DMS).
This paper investigates the development of a DMS framework for the cold rolling and press hardening process chain. In conjunction with conventional data acquisition methods employed for cold rolling, novel data acquisition techniques are introduced specifically tailored for press hardening, ensuring the comprehensive availability of relevant data. Moreover, a data pipeline is implemented to enable automatic processing, visualization, and analysis of process data. To facilitate seamless data linkage across processes in the DMS, an ID-system is introduced. Finally, the developed framework’s validity is demonstrated by creating a DMS for press-hardened MMnS parts, showcasing its potential for practical applications.

Published: May 2024

Abstract
This study investigates the challenges of reverse engineering in finite element modelling of sheet metal forming, specifically for the Volvo XC90 front door inner component. Advanced models incorporating anisotropic behaviour of steel and non-linear friction are compared against actual real-world measurements. The methodology involves simplifying complex continuous parameters into more manageable representative data sets and assessing model accuracy under both uniform and varied blank holder force settings, guided by measured contact pressure distributions. Although the results indicate an improvement in accuracy, they underscore the need for additional methodological improvements and more accurate replication of tooling effects to enhance the fidelity and effectiveness of these models.
Influence of Hole Preparation Technique on Stretch Flangeability of Aluminium Alloys
Authors: Kumar Vinay , Kumar D Ravi 
Published: May 2024

Abstract
Application of aluminium alloys has increased for light-weighting the sheet metal parts in manufacturing of automobiles. Formability is important in sheet metal forming of aluminium alloys. In the assessment of formability of sheet metals, stretch flangeability or edge formability is an important aspect in application such as flanges or plunged rims. The stretch flangeability refers to the ability to avoid cracking during hole expansion and it is evaluated by performing the hole expansion test. Besides material properties, hole making process also influences the stretch flangeability of aluminium alloys. In this work, the stretch flangeability of two Al-Mg alloys has been investigated through hole expansion tests by using three different hole making techniques namely punching, water jet cutting and laser cutting. The stretch flangeability of aluminium alloys has been compared with that of a high strength steel (Dual phase steel of grade DP600) which is more commonly used steel for stretch flanging applications.
Process design for flexible T-profile-rolling of tailored thickness stringers with different cross sections
Authors: Aign F S , Kilz J , Groche P 
Published: May 2024

Abstract
A new process, called flexible T-profile-rolling, is being developed to produce T-profiles with variable thickness distribution in longitudinal direction by flexible rolling. These tailored thicknesses allow for load-adapted and weight-optimised design of stringer profiles for aircrafts. The new process can replace the chemical milling currently used in the production of stringers and enables a more environmentally friendly and resource-saving production of the thickness changes. In order to achieve uniform thicknesses in the web and flange of the T-profile, a new rolling stand with rolls inclined against the T-profile and varying roll radii was developed. However, the varying roll radii cause different longitudinal strains in the profile cross-section due to the varied contact areas between the roll and the rolling stock, resulting in unwanted profile bowing. This bowing depends on the profile dimensions, as the adjacent roll radii vary over the profile cross-sections.
This paper demonstrates the effects of profile dimensions on deflection through numerical investigations with different web heights, flange widths and thickness reductions. A straightening method is presented to obtain straight profiles as a function of the profile dimensions. The results show that this process can produce almost straight T-profiles with variable thicknesses for different cross section dimensions.
Air pollution impact on forecasting electricity demand utilizing CNN-PSO hyper-parameter optimization
Authors: Birdal Ramiz Gorkem 
Published: May 2024

Abstract
Electricity consumption is expected to increase considerably in the next few years, so forecasting and planning will become more important. A new method of forecasting electricity loads based on air pollution is presented in this paper. Air pollution indirect effects are not incorporated in current evaluations since they rely primarily on weather conditions, historical load data, and seasonality. The accuracy of electricity load forecasting improved by incorporating air pollution data and its potential effects, especially in regions where air quality heavily impacts energy consumption and generation patterns. This robust prediction model is capable of capturing the complex interactions between air pollution and electricity load by integrating innovative environmental factors with historical load data, weather forecasts, and other features. As part of the second contribution, we use metaheuristic algorithms to optimize hyper parameters, which provide advantages such as exploration capability, global optimization, robustness, parallelization, and adaptability making them valuable tools to improve machine learning models’ performance and efficiency. The study found that the correlation coefficient (R) between predicted and real electricity demand and supply was high, at 0.9911. Beyond that this approach reduces MAPE by up to 19.5% when CNN and particle swarm optimization are combined with utilizing innovative air pollution variables. As a result, the optimization results were robust compared to state-of-the-art results based on statistical metrics such as RMSE and MAPE. Lastly, we emphasize the importance of factoring in air pollution effects when forecasting and managing electricity loads; future research directions include developing integrated modeling frameworks that reflect the dynamic interaction between air quality, energy consumption, and renewable energy generation.
Water level measurement for reservoir dams with robotic total station during displacements monitoring
Authors: Zhou Jianguo , Gao He , Xiao Wei , Peng Duo 
Published: May 2024

Abstract
This study proposes a novel method for water level measurement of reservoir dams by utilizing the image sensor of robotic total station rather than requiring a staff gauge during displacements monitoring. The robotic total station is first aimed at the waterline manually and an image is captured by the telescope coaxial camera to obtain the initial elevation and waterline equation. In the periodic measurement stage, the zenith angle of the telescope is adjusted according to the predicted result to take pictures, and the waterline is extracted based on the parameters of the initial waterline equation through image processing technologies. The waterline is verified, and the water level elevation is estimated then. Simulation and field test results show that waterline extraction error affects the accuracy of the proposed method most, and an accuracy of around 2 pixels can be achieved for the waterline extraction method. And a water level measurement result with centimeter-level accuracy at a distance of about 350 m can be expected, which has engineering application prospect.
The Cambridge and London Experiences of Joseph Hussey
Authors: Dunan-Page Anne 
Published: May 2024

Abstract
This chapter examines the manuscript works of the Cambridge and London dissenting minister Joseph Hussey (1660–1726). Such archival documents help reassess the transformation of Calvinistic culture after the Toleration Act, but this chapter argues that they also contain evidence for the history of literature. Joseph Hussey’s unpublished works first question the nature of pastoral diaries, sometimes called ‘church books’, but also give detailed accounts of the practice of conversion narratives in early eighteenth-century Congregational churches. After rehearsing the complex nature of Hussey’s diary, and the problem of denominational identity among Presbyterians and Congregationalists, I turn to Hussey’s presentations of oral and written conversion narratives given in his congregations. The rich vocabulary of emotions that both applicants and hearers were expected to encounter shaped the delivery of the narratives at times along gender lines.
Introduction
Authors: Constantine Mary-Ann 
Published: May 2024

Abstract
This chapter opens with two very different encounters between English tourists and ‘native’ Welsh locals at Llanberis Lakes in the late 1790s. Pursuing those differences, it argues that the genre of the ‘home tour’ offers a varied and under-exploited body of material of interest across a number of disciplines, and occupies an interesting position at the intersection of literary and historical studies. Situating such encounters as examples of ‘cultural entanglement’, it focuses on three topics explored in more detail across the book: contact with and representations of Welsh language and culture; political and social unrest; and, responding to recent work by Andreas Malm and others, environmental history.
Epilogue and Conclusion
Authors: Finkel Stuart 
Published: May 2024

Abstract
The Epilogue opens with a conservative’s triumphal 1887 account of the failures of prisoner aid as part of a thorough routing of “nihilism.” This, however, while technically accurate on the initial struggles of émigré aid, missed less public activity and the persistence of covert domestic efforts, where authorities remained gravely concerned with charitable events serving as subterfuge for illicit fundraising. This shows, it is argued, how political philanthropy occupied a liminal space linking radicals to a broader circle of educated sympathizers and provided a connective tissue allowing the revolutionary/liberationist movement to be construed as continuous and cohesive. The 1890s, it is then noted, featured a resumption of efforts abroad, with newly arrived émigrés spurring Lavrov to head a Central Kassa in Paris, with an affiliate in Zurich. At the same time, the continuous existence of the St. Petersburg Society to Aid Political Exiles and Prisoners and the revival of its Moscow counterpart in the early to mid-1890s drew in the next generation of revolutionary leaders. With the upsurge of both worker and student activity later in the decade, Zasulich made appeals in London, while “Red Cross” groups proliferated throughout Russia, presaging even broader and larger organizations after the turn of the century.
Micro-Coring: A Novel Approach to Perioral Rejuvenation
Authors: Carruthers Katherine H , Vyas Krishna , Remy Katya , McCarty Justin C , Austen William G 
Published: May 2024

Abstract

Background
A long philtrum and poor perioral skin quality are stigmata of the aging face. Micro-Coring is a novel technology that allows for scarless skin removal.

Objectives
In this study we aimed to determine whether micro-coring can shorten the philtrum and improve perioral skin quality.

Methods
A retrospective cohort study was performed on patients who underwent facelift with perioral micro-coring and age- and BMI-matched controls who underwent facelift alone. Preoperative and postoperative 3-dimensional facial imaging was performed. Standard perioral distances and percentage of change were calculated. Perioral skin quality was evaluated by blinded raters with the Scientific Assessment Scale of Skin Quality (SASSQ) and Global Aesthetic Improvement Scale (GAIS).

Results
Thirteen patients and 13 controls were included, with a mean follow-up of 8.9 months (range 3.0-21.5). Patients had significantly shorter mean philtrum length postoperatively compared to preoperatively, with an average decrease of 6.18% (±2.25%; P &lt; .05). Controls did not experience significant changes in philtrum length (P &gt; .05). There were no significant changes in other perioral measurements. Perioral skin elasticity and wrinkles significantly improved in patients compared to controls and patients had significantly greater GAIS scores (P &lt; .05).

Conclusions
Micro-Coring can achieve perioral rejuvenation through measurable shortening of the philtrum and observable improvement in skin quality. Nonsurgical techniques continue to find new ways to achieve aesthetic goals without significant recovery or scarring and offer value to patients and clinicians.

Authors: Luke Joanne Nicole , Bessarab Dawn , Smith Kate , LoGiudice Dina , Flicker Leon , Gilchrist Lianne , Dow Briony , Temple Jeromey 
Published: May 2024

Abstract

Objectives
This study aimed to determine the proportion of older Aboriginal and Torres Strait Islander peoples participating in cultural events and activities and determine the demographic and sociocultural characteristics associated with participation.

Methods
The Australian Bureau of Statistics National Aboriginal and Torres Strait Islander Social Survey (2014–2015) was used to measure the prevalence of participation in cultural events and activities. Multivariate logistic regression models were used to measure associations. Sociocultural factors were selected by matching survey items to the 12 sociocultural factors described in the Good Spirit Good Life Framework, a culturally validated quality-of-life tool for older people.

Results
The majority (62.0%) of survey respondents 45 years and older participated in cultural events (e.g., ceremonies, funerals/sorry business, NAIDOC week activities, sports carnivals, festivals/carnivals) or were involved in organizations. Many (58.5%) also participated in activities (e.g., fishing, hunting, gathering wild plants/berries, arts/crafts, music/dance/theater, writing/telling of stories). In regression models including demographic and cultural variables, participation in cultural events was highest among people living remotely (odds ratio [OR] = 2.71), reporting recognition of homelands (OR = 2.39), identifying with a cultural group (OR = 3.56), and those reporting having a say in their communities (OR = 1.57), with similar odds seen for participation in activities. Participation was inversely proportional to increasing age, with a greater proportion of females participating in events and males in activities.

Discussion
The social lives of older Aboriginal and Torres Strait Islander people were characterized by widespread participation in cultural events and activities. These findings provide important insights into services as they support older people to live a good life.
Fundamental Monopole Operators and Embeddings of Kac-Moody Affine Grassmannian Slices
Authors: Muthiah Dinakar , Weekes Alex 
Published: May 2024

Abstract
Braverman, Finkelberg, and Nakajima define Kac-Moody affine Grassmannian slices as Coulomb branches of $3d$ ${\mathcal{N}}=4$ quiver gauge theories and prove that their Coulomb branch construction agrees with the usual loop group definition in finite ADE types. The Coulomb branch construction has good algebraic properties, but its geometry is hard to understand in general. In finite types, an essential geometric feature is that slices embed into one another. We show that these embeddings are compatible with the fundamental monopole operators (FMOs), remarkable regular functions arising from the Coulomb branch construction. Beyond finite type these embeddings were not known, and our second result is to construct them for all symmetric Kac-Moody types. We show that these embeddings respect Poisson structures under a mild “goodness” hypothesis. These results give an affirmative answer to a question posed by Finkelberg in his 2018 ICM address and demonstrate the utility of FMOs in studying the geometry of Kac-Moody affine Grassmannian slices, even in finite types.
Metabolite cross-feeding enables concomitant catabolism of chlorinated methanes and chlorinated ethenes in synthetic microbial assemblies
Authors: Chen Gao , Yang Yi , Yan Jun , Löffler Frank E 
Published: May 2024

AbstractIsolate studies have been a cornerstone for unraveling metabolic pathways and phenotypical (functional) features. Biogeochemical processes in natural and engineered ecosystems are generally performed by more than a single microbe and often rely on mutualistic interactions. We demonstrate the rational bottom-up design of synthetic, interdependent co-cultures to achieve concomitant utilization of chlorinated methanes as electron donors and organohalogens as electron acceptors. Specialized anaerobes conserve energy from the catabolic conversion of chloromethane or dichloromethane to formate, H2, and acetate, compounds that the organohalide-respiring bacterium Dehalogenimonas etheniformans strain GP requires to utilize cis-1,2-dichloroethenene and vinyl chloride as electron acceptors. Organism-specific qPCR enumeration matched the growth of individual dechlorinators to the respective functional (i.e. dechlorination) traits. The metabolite cross-feeding in the synthetic (co-)cultures enables concomitant utilization of chlorinated methanes (i.e. chloromethane and dichloromethane) and chlorinated ethenes (i.e. cis-1,2-dichloroethenene and vinyl chloride) without the addition of an external electron donor (i.e. formate and H2). The findings illustrate that naturally occurring chlorinated C1 compounds can sustain anaerobic food webs, an observation with implications for the development of interdependent, mutualistic communities, the sustenance of microbial life in oligotrophic and energy-deprived environments, and the fate of chloromethane/dichloromethane and chlorinated electron acceptors (e.g. chlorinated ethenes) in pristine environments and commingled contaminant plumes.

Abstract
The cyst of the Canal of Nuck, or hydrocele, is a rare pathological condition in the female inguinal region. We present a 44-year-old female with a cystic lesion in the right inguinal area, detailing clinical symptoms, differential diagnosis and imaging findings. Surgical intervention involved complete cyst excision, with no recurrence during the follow-up. This case underscores the importance of accurate diagnosis and targeted surgical treatment for favourable outcomes in managing rare anatomical variations like the Canal of Nuck cyst.
Non-canonical mRNA translation initiation in cell stress and cancer
Authors: Mahé Mélanie , Rios-Fuller Tiffany , Katsara Olga , Schneider Robert J 
Published: May 2024

Abstract
The now well described canonical mRNA translation initiation mechanism of m7G ‘cap’ recognition by cap-binding protein eIF4E and assembly of the canonical pre-initiation complex consisting of scaffolding protein eIF4G and RNA helicase eIF4A has historically been thought to describe all cellular mRNA translation. However, the past decade has seen the discovery of alternative mechanisms to canonical eIF4E mediated mRNA translation initiation. Studies have shown that non-canonical alternate mechanisms of cellular mRNA translation initiation, whether cap-dependent or independent, serve to provide selective translation of mRNAs under cell physiological and pathological stress conditions. These conditions typically involve the global downregulation of canonical eIF4E1/cap-mediated mRNA translation, and selective translational reprogramming of the cell proteome, as occurs in tumor development and malignant progression. Cancer cells must be able to maintain physiological plasticity to acquire a migratory phenotype, invade tissues, metastasize, survive and adapt to severe microenvironmental stress conditions that involve inhibition of canonical mRNA translation initiation. In this review we describe the emerging, important role of non-canonical, alternate mechanisms of mRNA translation initiation in cancer, particularly in adaptation to stresses and the phenotypic cell fate changes involved in malignant progression and metastasis. These alternate translation initiation mechanisms provide new targets for oncology therapeutics development.
The topography of thought
Authors: Berger Jonah , Toubia Olivier 
Published: May 2024

AbstractWhether speaking, writing, or thinking, almost everything humans do involves language. But can the semantic structure behind how people express their ideas shed light on their future success? Natural language processing of over 40,000 college application essays finds that students whose writing covers more semantic ground, while moving more slowly (i.e. moving between more semantically similar ideas), end up doing better academically (i.e. have a higher college grade point average). These relationships hold controlling for dozens of other factors (e.g. SAT score, parents' education, and essay content), suggesting that essay topography encodes information that goes beyond family background. Overall, this work sheds light on how language reflects thought, demonstrates that how people express themselves can provide insight into their future success, and provides a systematic, scalable, and objective method for quantifying the topography of thought.
