Fault detection in automated production systems based on a long short-term memory autoencoder
Authors: Windmann Stefan , Westerhold Tim 
Published: January 2024

Abstract
In this paper, a hybrid model of regularized Long Short-Term Memory (LSTM) and autoencoder for fault detection in automated production systems is proposed. The presented LSTM autoencoder is used as a stochastic process model, which captures the normal behavior of a production system and allows to predict the probability distribution of sensor data. Discrepancies between the observed sensor data and the predicted probability density distribution are detected as potential faults. The approach combines the advantages of LSTMs and autoencoders: The correlations between individual sensor signals are exploited by an autoencoder, while the temporal dependencies are captured by LSTM neurons. A key challenge in training such a process model from historical data is to control the information passed through the latent space of the autoencoder. Different regularization methods are investigated for this purpose. Fault detection with the proposed LSTM autoencoder has been evaluated on the use case of an industrial penicillin production, achieving significantly improved results in comparison to the baseline LSTM.
Quantum computer-aided job scheduling for storage and retrieval systems
Authors: Windmann Stefan 
Published: January 2024

Abstract
In this paper, a quantum computer-aided approach to job scheduling for automated storage and retrieval systems is introduced. The approach covers application cases, where various objects need to be transported between storage positions and the order of transport operations can be freely chosen. The objective of job scheduling is to arrange the transport operations in a sequence, where the cumulative costs of the transport operations and empty runs between subsequent transport operations are minimized. The scheduling problem is formulated as an asymmetric quadratic unconstrained binary optimization (QUBO) problem, in which the transport operations are modeled as nodes and empty runs are modeled as edges, with costs assigned to each node and each edge. An Quantum Approximate Optimization Algorithm (QAOA) is used to solve the QUBO. Evaluations of the quantum computer-aided job scheduling approach have been conducted on the IBM Q System One quantum computer in Ehningen. In particular, the running time for the solution of the QUBO has been investigated, as well as the scalability of the approach with respect to the required number of qubits.
SysML’ – incorporating component properties in early design phases of automated production systems

Published: January 2024

Abstract
Properties and environmental dependencies of mechatronic components like gear-drives and motors impact the overall performance of automated Production Systems. These properties, often in the form of characteristic curves, are only accessible from suppliers’ documents, like operating instructions or online catalogs. The proposed SysML’ profile integrates artifacts from SysML and UML into disciplinary views. It includes a reference mechanism to REXS (standard for gear properties) and ECLASS (standard for product data like UNSPSC) to overcome the semantic inconsistency of component properties and inclusion of curves. A metamodel is used for a more precise presentation of the proposed reference mechanism. Due to the static nature of a profile, a Business Process Modeling Notation is used to dynamically illustrate the benefits of SysML’ in the workflow.

Abstract

Objectives
Hemoglobinopathies, including thalassemia and hemoglobin (Hb) variants, are common hematological disorders in tropical countries. Accurate and precise separation of hemoglobin types and reliable quantitation are necessary for differential diagnosis of these disorders.

Methods
We have evaluated the analytical performances of premier resolution-high-performance liquid chromatography (PR-HPLC; Trinity Biotech, Co. Wicklow, Ireland) to assist in the presumptive diagnosis of thalassemia and Hb variants commonly found in Southeast Asian countries. HbA0, HbA2, HbE, and HbF levels were separated and quantified in 120 blood samples from unrelated adult subjects and compared with those analyzed by capillary zone electrophoresis (CZE; CAPILLARYS™ 2, Sebia, Norcross, GA, US). The Hb analysis patterns of Hb variants obtained from the PR-HPLC system were also compared to those obtained from HPLC (VARIANT II, β-thalassemia Short Program, Bio-Rad, Laboratories, Hercules, CA, US) and CZE systems.

Results
The PR-HPLC had excellent precision with a coefficient of variation (CV) for HbA2 quantitation of 3.8 % within-run and 5.2 % between-run. The levels of HbA2/E quantified by the PR-HPLC system correlated well with those of the CZE system (r=0.997). In addition, thalassemia interpretation results obtained from the PR-HPLC and the CZE showed 100 % agreement. Moreover, chromatograms of the PR-HPLC were also comparable to those of VII-HPLC and CAP2-CZE electropherograms.

Conclusions
The PR-HPLC system would be applicable to diagnose common forms of thalassemia and Hb variants in Southeast Asia.
Wear and corrosion behavior of TiC and WC coatings deposited on high-speed steels by electro-spark deposition
Authors: Mertgenç Ersan 
Published: January 2024

Abstract
Electro-spark deposition (ESD) is one of the most effective methods for improving the surfaces of metallic materials by applying ceramic-based cermet coatings. In this study, TiC and WC coatings were deposited on the surface of AISI M2 high-speed steel using the ESD method. Subsequently, the coated surfaces were examined through microstructure, phase structure, microhardness, friction, wear, and electrochemical corrosion tests, and compared with untreated AISI M2 steel. The TiC and WC phase coatings obtained with ESD resulted in a significant improvement, with hardness levels exceeding four times that of AISI M2 steel, leading to reduced wear volume losses and friction coefficients. Furthermore, the cermet coatings formed on the surface exhibited 2–3 times improvement in corrosion resistance due to their lower conductivity. This study demonstrates that WC coatings may offer a more effective solution for enhancing the wear resistance of AISI M2 steel, while TiC coatings could be more effective in improving corrosion resistance.
When life is no longer a journey: the effect of the COVID-19 pandemic on the metaphorical conceptualization of life among Hungarian adults – a representative survey
Authors: Benczes Réka , Benczes István , Ságvári Bence , Szabó Lilla Petronella 
Published: January 2024

AbstractThere is ample research on how metaphors oflifevary both cross-culturally and within culture, with age emerging as possibly the most significant variable with regard to the latter dimension. However, no representative research has yet been carried on whether variation can also occur across time. Our paper attempts to fill this gap in the literature by exploring whether a major crisis, such as the COVID-19 pandemic, can induce variation in howlifeis metaphorically conceptualized throughout society. By drawing on the results of a nationwide, representative survey on the metaphorical preferences forlifeamong Hungarian adults carried out during the second wave of the COVID-19 pandemic, we hypothesized that the pandemic would induce a revolutionary change (in the sense of the change being swift, as opposed to gradual) in how Hungarian adults metaphorically conceptualizelife, as compared to the metaphorical preferences of the pre-COVID-19 era. We expected this variation to manifest itself in the emergence of novel metaphorical source domains and a realignment in metaphorical preferences. Our results, however, indicate that novel conceptualizations emerged only as one-off metaphors; Hungarians mostly rely on a stock collection oflifemetaphors even in times of crises, with changes happening mostly in the form of shifts in metaphorical preferences. Our study also found that the choice of preference of the source domains showed less alterations among older adults – implying that the older we get, the more resistant to change our metaphorical conceptualizations become, even under extreme conditions such as COVID-19.

Interfacial microstructure and mechanical properties of Si3N4/Invar joints using Ag–Cu–In–Ti with Cu foil as an interlayer
Authors: Zhao Tong , Mo Defeng , Li Xue , Gong Haimei 
Published: January 2024

Abstract
Si3N4 and Invar alloy brazed joints were achieved using two types of Ag-based interlayers: a Ag–Cu–In–Ti foil and a Ag–Cu–In–Ti/Cu/Ag–Cu multi-interlayer. The results showed that when only using a single Ag–Cu–In–Ti filler, the wave-shaped Fe2Ti + Ni3Ti intermetallic compounds are concentrated in the middle of the brazing seam. When adding Cu as the interlayer, the dissolution of the Cu interlayer formed a large number of Cu(s,s) blocks of different sizes in the brazing seam, which hindered the concentrated distribution of Fe2Ti + Ni3Ti intermetallic compounds in the brazing seam. As a result, Fe2Ti and Ni3Ti were dispersedly distributed in the brazing seam, increasing the shear strength of the brazed joint. The shear strength of brazed joints was increased by 82 % compared to joints brazed with a single Ag–Cu–In–Ti filler when the Cu interlayer was added.

Published: January 2024

Abstract
We demonstrate the facile fabrication of metal-wire-embedded microtrenches interconnected with semiconducting ZnO nanowires (ZNWs) through the continuous mechanical machining of micrograting trenches, the mechanical embedding of solution-processable metal wires therein, and the metal-mediated hydrothermal growth of ZNWs selectively thereto. The entire process can be performed at room or a very low temperature without resorting to vacuum, lithography, and etching steps, thereby enabling the use of flexible polymer substrates of scalable sizes. We optimize the fabrication procedure and resulting structural characteristics of this nanowire-interconnected flexible trench-embedded electrode (NIFTEE) architecture. Specifically, we carefully sequence the coating, baking, and doctor-blading of an ionic metal solution for the embedding of clean metal wires, and control the temperature and time of the hydrothermal ZNW growth process for faithful interconnections of such trench-embedded metal wires via high-density ZNWs. The NIFTEE structure can function as a bending-sensitive optoelectronic sensor, as the number of ZNWs interconnecting the neighboring metal wires changes upon mechanical bending. It may benefit further potential applications in diverse fields such as wearable technology, structural health monitoring, and soft robotics, where bending-sensitive devices are in high demand.

The quest to decode the complex supraspinal mechanisms that integrate cutaneous thermal information in the central system is still ongoing. The dorsal horn of the spinal cord is the first hub that encodes thermal input which is then transmitted to brain regions via the spinothalamic and thalamo-cortical pathways. So far, our knowledge about the strength of the interplay between the brain regions during thermal processing is limited. To address this question, we imaged the brains of adult awake male mice in resting state using Functional Ultrasound imaging during plantar exposure to constant and varying temperatures. Our study, reveals for the first time: i) a dichotomy in the response of the somato-motor-cingulate cortices and the hypothalamus, which was never described before, due to the lack of appropriate tools to study such regions with both good spatial and temporal resolutions. ii) We infer that cingulate areas may be involved in the affective responses to temperature changes. iii) Colder temperatures (ramped down) reinforces the disconnection between the somato-motor-cingulate and hypothalamus networks. iv) Finally, we also confirm the existence in the mouse brain of a brain mode characterized by low cognitive strength present more frequently at resting neutral temperature. The present study points towards the existence of a common hub between somato-motor and cingulate regions, whereas hypothalamus functions are related to a secondary network.Significance StatementVery little is known regarding the brain areas involved in thermal coding and the interactions between them. Using an emerging neuroimaging technique in freely moving mice during exposure to either constant neutral / warm or cold sensation; or varying temperature. We identified dynamic brain states. Some are observed more frequently during exposure to cold stimuli. Through the demonstration of reproducible and specific fingerprints of dynamic brain modes, this study will open the path to future investigations on the alterations of these brain states during cold sensing in animal models and human subjects affected by peripheral neuropathy.
Diagnostic utility of repeat fine needle aspirations of benign thyroid nodules
Authors: Mendoza Rachelle P , Simon Richard Cody , Cipriani Nicole A , Antic Tatjana 
Published: January 2024

Objective
This study aims to analyze the diagnostic utility of multiple repeat FNA on thyroid nodules with initially benign diagnosis.

Methods
In a 5-year period, 1658 thyroid nodules with initially benign FNAs were retrospectively reviewed and followed for subsequent resection and repeat biopsy.

Results
Out of 2150 thyroid nodules, 1658 (77.1%) were diagnosed as benign on FNAs. The average age at diagnosis was 57.4 years (range: 11–93 years), and most were females (83.8%). Repeat FNA was performed on 183 benign nodules, of which 141 (8.5%) were sampled a second time and 42 (2.5%) had two or more repeat samplings. For the benign nodules without repeat FNAs, 124 had benign resection. Of cases with one-time repeat FNA, most (n = 101) remained benign on repeat FNAs, 13 of which were benign on resection. Eleven had atypical repeat FNAs, five were resected, four of which were benign and one was atypical follicular neoplasm with HRAS and TERT promoter mutations. Of cases with multiple repeat FNA, most (n = 35) were still benign on repeat FNAs, one had benign resection. Two had atypical repeat biopsies, one was PTC on resection with CCD6::RET fusion. The positive predictive value significantly decreased from 41.1% on single FNA to 8.3% on one-time repeat (P < 0.001) and 16.7% on multiple repeat (P = 0.002). The total cost for the work-up of previously benign nodules was $285,454.

Conclusions
Repeat FNA biopsies did not provide an additional diagnostic value in the evaluation of benign thyroid nodules, and often led to unwarranted follow-up procedures and significantly increased health-care cost.

Published: January 2024

BACKGROUND
For adolescents, data on the long-term effectiveness of the BNT162b2 and mRNA-1273 vaccines against severe COVID-19 outcomes are scarce. Additionally, only a few studies have evaluated vaccine effectiveness (VE) for mRNA-1273 or heterologous mRNA vaccine schedules (ie, mixing BNT162b2 and mRNA-1273).

METHODS
Nationwide register-based 1-to-1 matched cohort analyses were conducted in Denmark, Finland, Norway, and Sweden between May 28, 2021, and April 30, 2023, to estimate VE for primary COVID-19 vaccine (2-dose) schedules among adolescents aged 12 to 17 years. Cumulative incidences of COVID-19–related hospitalization (primary outcome) and laboratory-confirmed SARS-CoV-2 infection (secondary outcome) were compared for vaccinated and unvaccinated at 6 months of follow-up using the Kaplan-Meier estimator. Country-specific VE (1-risk ratio) and risk differences (RD) were combined by random-effects meta-analyses.

RESULTS
The study included 526 966 primary schedule vaccinated adolescents. VE against COVID-19–related hospitalization was 72.6% (95% confidence interval [CI], 62.5–82.7) and RD was –2.8 (95% CI, –4.5 to –1.0) per 10 000 vaccinated for BNT162b2 at 6 months of follow-up compared with unvaccinated. The corresponding VE and RD were 86.0% (95% CI, 56.8–100.0) and –2.1 (95% CI, –4.0 to –0.2) per 10 000 vaccinated for mRNA-1273 and 80.7% (95% CI, 58.0–100.0) and –5.5 (95% CI, –15.5 to 4.6) per 10 000 vaccinated for heterologous mRNA vaccine schedules. Estimates were comparable when restricting to a period of omicron predominance and extending follow-up to 12 months.

CONCLUSIONS
Across 4 Nordic countries, severe COVID-19 in adolescents was a rare event. Compared with unvaccinated, BNT162b2, mRNA-1273, and heterologous mRNA vaccination schedules provided high protection against COVID-19–related hospitalization, including hospitalizations during the omicron period.

Published: January 2024

The northern region of Mozambique has a complex geological history, with an evolution that spans from the Precambrian Era to the Phanerozoic Era. In this work, we have integrated gravity and geothermal data to delineate the geotectonic evolution of the region, by estimating the thickness of the crust and the lithosphere through which was essential to generate a representative crustal model. It was necessary to complement the knowledge of structural geometry and tectonic evolution of the region. The data used in this study are the Bouguer and geoid anomalies, topography data, and radiogenic heat. These data were pre-processed, topography and geoid anomaly data were filtered by low-pass filter in the frequency and harmonic domains to remove undesirable effects associated with the sources. The data were used to estimate the thickness of the crust and lithosphere, as well as to determine the mean density distribution within the mantle. This was achieved by using a one-dimensional approach, considering the principle of local isostatic compensation, associated with equations governing the distribution of temperature in the crust. The Bouguer anomaly was used to generate a representative crustal 2D model of this region. The results showed that the crust is thinner in Nampula and Cabo Delgado provinces, with thickness ranging from 27 to 31 km, whereas in Niassa varies between 33 and 39 km. The analysis of lithospheric thickness indicates that the provinces of Nampula and Cabo Delgado present a thinning of the lithosphere, with values ranging from 150 to 165 km. Rather than Niassa province which exhibits a thicker lithosphere, ranging from 165 to 195 km. The obtained results underwent a comparative analysis with prior investigations, unveiling a noteworthy concurrence among these findings.
representação da pessoa negra na publicidade contemporânea brasileira
Authors: Stéfani Felício Lourenço Suéllen , Ramalho Procópio Xavier Mariana , Gonçalves Reis Ana Carolina 
Published: January 2024

Nas publicidades das décadas de 1900 a 1930, os clareadores de pele representavam uma proposta para as mulheres negras de pele retinta “melhorarem” de vida, além de indicarem uma equidade racial, individual e familiar. Dessa forma, a pele negra era tratada pela imprensa como uma pele feia, o que traria como consequências menores oportunidades no mercado de trabalho, sendo que havia uma preferência por representações de pessoas negras de tez mais clara. Na publicidade contemporânea podem ser observadas características como a ousadia e a inserção de produtos destinados a jovens negros, contudo, ainda são encontrados determinados resgastes de uma construção estereotipada, em que as habilidades intelectuais são menos valorizadas em detrimento das habilidades corporais. Deste modo, este artigo objetiva, através de uma discussão em torno da questão racial, refletir sobre a representação da pessoa negra na publicidade contemporânea, considerando os aspectos relacionados à prática do racismo, o que acabou por naturalizar determinadas representações que inferiorizam os negros. As discussões foram tecidas a partir de questões do racismo atrelado à escravidão e sobre aspectos relacionados ao padrão de beleza na publicidade em diferentes épocas. Foi possível verificar que para o homem negro é recorrente a sua imagem ser associada a habilidades da dança, configurando-se em um estereótipo que destitui a intelectualidade para a pessoa negra. Para a mulher negra, sua representação está relacionada à corporalidade, sendo suas características associadas à animalidade, à selvageria, ao grotesco. Observou-se ainda uma representação social baseada em estereótipos racistas, em que às pessoas brancas são associados adjetivos como a beleza e a popularidade, enquanto que para as pessoas negras são associados aspectos que se referem à feiura e à agressividade, por exemplo.
