Published: March 2024

Abstract
Despite the many advantages and increasing adoption of Electron Beam Powder Bed Fusion (PBF-EB) additive manufacturing by industry, current PBF-EB systems remain largely unstable and prone to unpredictable anomalous behaviours. Additionally, although featuring in-situ process monitoring, PBF-EB systems show limited capabilities in terms of timely identification of process failures, which may result into considerable wastage of production time and materials. These aspects are commonly recognized as barriers for the industrial breakthrough of PBF-EB technologies. On top of these considerations, in our research we aim at introducing real-time anomaly detection capabilities into the PBF-EB process. To do so, we build our case-study on top of a Arcam EBM A2X system, one of the most diffused PBF-EB machines in industry, and make access to the most relevant variables made available by this machine during the layering process. Thus, seeking a proficient interpretation of such data, we introduce a deep learning autoencoder-based anomaly detection framework. We demonstrate that this framework is able not only to early identify anomalous patterns from such data in real-time during the process with a F1 score around 90%, but also to anticipate the failure of the current job by 6 h, on average, and in one case by almost 20 h. This avoids waste of production time and opens the way to a more controllable PBF-EB process.
Nonlinearly Optimized Dual Stereo Visual Odometry Fusion
Authors: Cabrera-Ávila Elizabeth Viviana , da Silva Bruno Marques Ferreira , Gonçalves Luiz Marcos Garcia 
Published: March 2024

AbstractVisual odometry (VO) is an important problem studied in robotics and computer vision in which the relative camera motion is computed through visual information. In this work, we propose to reduce the error accumulation of a dual stereo VO system (4 cameras) computing 6 degrees of freedom poses by fusing two independent stereo odometry with a nonlinear optimization. Our approach computes two stereo odometries employing the LIBVISO2 algorithm and later merge them by using image correspondences between the stereo pairs and minimizing the reprojection error with graph-based bundle adjustment. Experiments carried out on the KITTI odometry datasets show that our method computes more accurate estimates (measured as the Relative Positioning Error) in comparison to the traditional stereo odometry (stereo bundle adjustment). In addition, the proposed method has a similar or better odometry accuracy compared to ORB-SLAM2 and UCOSLAM algorithms.

AbstractThe crystal structure of [Cu3(C7H5O3)4(C20H20NO5)2(H2O)2]·2(H2O) (1) and analysis of temperature and field dependence of magnetic susceptibility is reported in this work. The structure of 1 is composed of trinuclear complex units and water molecules. The middle copper atom occupies the center of symmetry. N, O-bonded (6,7-dimethoxy-isoquinolin-1-yl)-(3,4-di­methoxy-phenyl)-methanolato ligands, 2-hydroxybenzoates with bridging carboxylic groups, and oxo-bridged water molecules connect the middle Cu(II) atom with the terminal copper atoms. Two 2-hydroxybenzoates coordinate the terminal copper atoms via one carboxylic oxygen and an O atom of the hydroxyl group. The analysis of copper coordination by bond-valence sum approach and relevant structural correlation is consistent with hexacoordinated Cu(II) centers. Cu···Cu separation is 3.0269(3) Å. The magnetism of 1 shows a strong ferromagnetic interaction between the neighboring metallic centers accompanied by very weak antiferromagnetic intermolecular interactions. The complex units are mutually held by π···π stack interactions of 2-hydroxybenzoates and hydrogen bonds.

Parametric study for model calibration of a friction-damped turbine blade with multiple test data
Authors: Ferhatoglu Erhan , Botto Daniele , Zucca Stefano 
Published: March 2024

AbstractModel updating using multiple test data is usually a challenging task for frictional structures. The difficulty arises from the limitations of nonlinear models which often overlook the uncertainties inherent in contact interfaces and in actual test conditions. In this paper, we present a parametric study for the model calibration process of a friction-damped turbine blade, addressing the experimentally measured response variability in computational simulations. On the experimental side, a recently developed test setup imitating a turbomachinery application with mid-span dampers is used. This setup allows measuring multiple responses and contact forces under nominally identical macroscale conditions. On the computational side, the same system is modeled in a commercial finite element software, and nonlinear vibration analyses are performed with a specifically developed in-house code. In numerical simulations, the multivalued nature of Coulomb’s law, which stems from the inherent variability range of static friction forces in permanently sticking contacts, is considered to be the main uncertainty. As the system undergoes vibration, this uncertainty propagates into the dynamic behavior, particularly under conditions of partial slip in contacts, thus resulting in response variability. A deterministic approach based on an optimization algorithm is pursued to predict the limits of the variability range. The model is iteratively calibrated to investigate the sensitivity of response limits to contact parameters and assembly misalignment. Through several iterations, we demonstrate how uncertain initial contact conditions can be numerically incorporated into dynamic analyses of friction-damped turbine blades. The results show a satisfactory level of accuracy between experiments and computational simulations. This work offers valuable insights for understanding what influences test rig response and provides practical solutions for numerical simulations to improve agreement with experimental results.
Labor market peer firms: understanding firms’ labor market linkages through employees’ internet “also viewed” firms
Authors: Li Nan 
Published: March 2024

Abstract
This paper studies the grouping of firms based on their labor-market connections, a significant departure from the traditional approach of grouping based on product-market connections. It also proposes a measure of labor market peers by analyzing the “also viewed” companies on two major online labor market platforms, LinkedIn and Glassdoor. Using the labor market peer measure, I examine whether firms that hire employees with similar skills and that are presumably exposed to the same labor-related risks and shocks exhibit a strong comovement of stock returns and accounting-based performance variables. I find that labor market peers overlap but differ from traditional product-market-based industry groupings, have significant incremental power to explain stock return and accounting-based performance measure comovements, and outperform traditional industry groupings in explaining return and wage comovements when a base firm shares more labor skills with its peers. Overall, the study highlights that labor market peers capture fundamental linkages between firms that are challenging to identify using traditional industry measures.
“So Lonely”: Comparative Law and the Quest for Interdisciplinary Legal Education
Authors: Resta Giorgio 
Published: March 2024

AbstractFor various reasons, that will be recalled and analysed throughout this paper, interdisciplinarity has become the keyword for any debate on legal education reform. However, what is meant by interdisciplinarity and how it should be achieved is open for discussion. Paradigms of “scientificity” of the law vary dramatically among legal cultures. Whereas in the US the advent of a more ‘substantial’ legal thought after the New Deal went hand in hand with the rise of the interdisciplinary paradigm, in Europe the traditional assumption of law’s autonomy has repeatedly been challenged, eroded and adapted, but it still represents the bulwark of the orthodox approach to law and legal scholarship. In the Continent, mainstream legal scholarship does not take as its object the social reality, but only the gamut of rules recognized as binding norms. Coherent with this approach is a model of legal education built around certain axioms, such as the statist and nationalist attitude, the extreme compartmentalization among the various branches of law, and the blindness to its surroundings. Comparative law is one of the few disciplines that provide a different role model for a legal scholar who is apt to confront the challenges of complex societies. Keeping at a reasonable distance the authority paradigm, embodying the spirit of enquiry and cherishing the values of pluralism (both in terms of legal pluralism and cognitive openness), comparativists may give specific content to the paradigm of the jurist as a social engineer. Comparative law may therefore offer an invaluable contribution to the debate on legal education reform.

AbstractThe health of the gastrointestinal tract in cattle is one of the factors influencing adequate nutrient absorption and body weight gain. This study aimed to evaluate the prevalence of lesions found in the abomasum of Polish fattening Holstein-Friesian bulls. A total of 149 abomasa from adult bulls from two voivodeships of central Poland were inspected for pathologicalanatomic position (displacement, volvulus), impaction, mucosal membrane lesions (inflammation, hyperplasia), and signs of parasite infestation(Moroccan leather, worm nodules) in one of the Polish abattoirs just after slaughter. Among all the examined males no lesions were observed in only 8 individuals. The most common findings were erosions (75.8%) and type 1 ulcerations (48.3%) of the body, pylorus, or both locations. Signs of parasite infestations were observed in 78.5% of the inspected animals. Significant differences correlated with age were found in the prevalence of healed ulcers, and between voivodeships in the prevalence of type 2 ulcers. The findings of this study indicate that most fattening bulls in Poland suffer from subclinical forms of abomasa inflammation (both diffuse and focal) and middle-large abomasum parasites invasions, which can influence the economics and profitability, as well as welfare, of livestock production.

AbstractGnomoniopsis smithogilvyi (Gnomoniaceae, Diaporthales) is the main causal agent of chestnut brown rot on sweet chestnut worldwide. The rotting of nuts leads to alterations in the organoleptic qualities and decreased fruit production, resulting in significant economic losses. In 2021, there was an important outbreak of chestnut rot in southern Galicia (Spanish northwest). The profile of secondary metabolites from G. smithogilvyi was studied, especially to determine its capability for producing mycotoxins, as happens with other rotting fungi, due to the possible consequences on the safety of chestnut consumption. Secondary metabolites produced by isolates of G. smithogilvyi growing in potato dextrose agar (PDA) medium were identified using liquid chromatography coupled with high-resolution mass spectrometry. Three metabolites with interesting pharmacological and phyto-toxicological properties were identified based on their exact mass and fragmentation patterns, namely adenosine, oxasetin, and phytosphingosine. The capacity of G. smithogilvyi to produce adenosine in PDA cultures was assessed, finding concentrations ranging from 176 to 834 µg/kg. Similarly, the production of mycotoxins was ruled out, indicating that the consumption of chestnuts with necrotic lesions does not pose a health risk to the consumer in terms of mycotoxins.
Impact of climate change on formation of nitrogenous disinfection by-products. Part II: water blooming and enrichment by humic substances

Published: March 2024

AbstractClimate change affects the concentration and characteristics of dissolved organic matter (DOM) in surface water. The changes in composition of DOM have many implications to drinking water quality, especially in the case of formation of disinfection by-products (DBPs). The aim of this study was to investigate the formation of nitrogenous DBPs (N-DBPs) during chlorination and chloramination, caused by the alternation of surface water’s DOM driven by climate change. For this reason, two different cases were examined: (a) rise of algal organic matter (AOM) due to water blooming and (b) water enrichment by humic substances. The target compounds were haloacetonitriles (HANs), haloacetamides (HAcAms), and halonitromethane (TCNM). The results showed that Anabaena appears to be a major precursor for HAcAms and TCNM, while humic acids are precursors for HANs. The results of the mixtures presented the same pattern. During the water blooming case, HAcAms and TCNM formation are in favor, while during water enrichment by humic substances case, HANs is the N-DBP group with higher formation yield. Cloraminated samples presented higher values of cytotoxicity and genotoxicity compared to the chlorinated.

Congo red dye degradation using Fe-containing mineral as a reactive material derived from waste foundry dust
Authors: Kim Hyunsoo , Park Chulhyun , Choi Nagchoul , Cho Kanghee 
Published: March 2024

AbstractThis study investigated the applicability of industrial waste. The high affinity of Fe-based products is widely used for industrial effluents because of their capability to oxidize contaminants. Waste foundry dust (WFD) is an Fe oxide that has been investigated as a potential reactive material that causes the generation of reactive oxidants. We aimed to investigate the physicochemical properties of WFD and the feasibility in the Fenton oxidation process. The WFD was used as a catalyst for removing Congo red (CR), to evaluate the generation of •OH and dissolution of Fe during the oxidation process. The linkage of •OH generation by WFD with eluted Fe(II) through the Fe dissolution was found. The Fenton oxidation reaction, CR degradation was affected by H2O2 concentration, initial pH, WFD dosage, initial CR concentration, and coexisting anions. The CR degradation efficiency increased with an increase in H2O2 concentration and WFD dosage. In addition, chloride and sulfate in solution promoted CR degradation, whereas carbonate had a negative effect on the Fenton oxidation process. The elution of Fe promotes CR degradation, over three reuse cycles, the degradation performance of the CR decreased from 100 to 81.1%. For the Fenton oxidation process, •OH generation is linked to Fe redox cycling, the surface passivation and Fe complexes interrupted the release of reactive oxidants, which resulted in the degradation of the CR decreased. This study proposed that WFD can serve as catalysts for the removal of CR.

Published: March 2024

Zusammenfassung
Inklusive Schulentwicklung erfordert, dass Large-Scale-Assessments zum Bildungsmonitoring die Leistungen auch auf den unteren Kompetenzstufen konzeptionell fundiert und methodisch angemessen erheben. Im Gegensatz zu bisherigen Aufgabensets in Bildungsmonitoringstudien, die für diesen Kompetenzbereich nur verzerrte Ergebnisse liefern, wird in einer ersten explorativen Neukonzeption speziell für Jugendliche aus dem sonderpädagogischen Schwerpunkt Lernen gezeigt, dass Aufgabenpools für die unteren Kompetenzbereiche möglich sind. Ziel dieses Beitrags ist es, alle 88 anwendungsbezogenen empirisch leichten bzw. schweren Aufgaben im neukonzipierten Aufgabenpool auf den unteren Kompetenzstufen hinsichtlich Modellierungsphasen, Authentizität und Relevanz zu charakterisieren. Im Vergleich zum bisherigen Aufgabenpool erwiesen sich im neu konzipierten mehr Items mit Relevanz in eher authentischen und in privaten Kontexten als geeignet. Dieser explorative Befund ist bei der Weiterentwicklung eines Kompetenzmodells für Large-Scale-Assessments in inklusiven Settings zu berücksichtigen.

Published: March 2024

AbstractFixed-wing hybrid vertical take-off and landing (VTOL) unmanned aerial vehicles (UAV) are popular due to their interoperability in the military and civilian domains, primarily where significant terrain difficulties exist for humans. Additionally, they can operate without requiring any runway infrastructure and have extended air endurance and efficiency. Since the hybrid UAV operates in distinct flight modes, viz., (a) VTOL and (b) fixed-wing cruise, carrying different payloads, the airframe structure requires careful design and manufacturing to realize sufficient strength. This experimental study aimed to identify the best combinations of various composite materials for manufacturing a lightweight, low-altitude long endurance (LALE) hybrid VTOL UAV. Primary materials include carbon fiber, Kevlar, fiber-reinforced plastic (FRP), resins, etc. Different rectangular test specimens of 120 × 5 mm size were made from ten different grades of carbon fiber, FRP, and resins using vacuum bagging. After properly curing these test specimens, we quantified their dynamic mechanical characteristics using various bending load experiments on a universal testing machine (UTM). An analysis of the experimental data facilitated the identification of the best composite combinations that provide maximum strength while reducing overall weight. Thus, we could understand the dynamic interplay between peak stress and test specimen weight. We also manufactured a UAV prototype using the identified combination and instrumented and flight-tested it to substantiate the experimental findings.
The Profile and Characteristics of Young People Accessing Recently Implemented Community Forensic Child and Adolescent Mental Health Services (F:CAMHS) in Northern Ireland
Authors: Walsh Colm , Anderson Philip , Caldwell Frances 
Published: March 2024

AbstractChildren under the age of 18 who are known to forensic child and adolescent mental health services often present with complex psychosocial and behavioural needs that are elevated compared with those in the general youth population. The Forensic Child and Adolescent Mental Health Service for Northern Ireland (FCAMHSNI) was commissioned in 2014 to support these children. Despite almost a decade of implementation, the profile and characteristics in the service remain under-analysed, impeding service improvement and making international comparisons more difficult. The primary aim of the current study was to address the regional gaps in how the needs of those accessing FCAMHSNI are understood. A secondary aim was to capture comparable data. Data on 107 accepted referrals are included in the analyses. The majority of cases within this time period were male (81.1%, n = 86) and the majority of presenting behaviours were related to violence and aggression 62.3% (n = 48). However, some forms of violence, such as harmful sexual behaviour, was relatively low when compared with other jurisdictions. Specific demographic characteristics such as gender and religious background appeared to be significant risk factors for referral to the service. Almost all of the sample are known to have experienced at least one potentially traumatic event (95.2%) and in more than one-third of cases, service users presented with co-morbid issues (35.6%, n = 37). These observations are discussed. This study adds to the growing international literature around the needs of forensically involved youth and helps to inform future service development and provision.
