Quantitative characterisation of acoustic emission source for composite failure mechanism under quasi-static three-point bending
Authors: Low S.K.
Published: March 2023

Abstract. Fibre reinforced composites have been discovered to have superior material properties compared to traditional materials. However, composite structures do have weaknesses which is highly susceptible to damage from accidental impacts. Passive approaches have gained popularity in recent years as these can be implemented using less structurally and electrically obtrusive sensor installations. The fundamental hypothesis is that every distinct impact event has a unique modal signature that can be exploited to distinguish between damaging and nondamaging impacts, and to characterize the severity of damage. Preliminary research showed that the possibility to determine the progressive failure mechanism in composite specimens subjected to three-point bending. Each failure mechanisms have its corresponding frequency bandwidth, and it can be seen by plotting the spectrogram of time-frequency analysis. However, the limitation of time-frequency analysis for identifying failure modes arises from the fact that there can be a confluence of modes having more-or-less the same group velocity hence, having the same arrival time in a time-frequency plot for a given frequency. This overlap makes it problematic to identify modes unambiguously from a time-frequency analysis. The modes can be more clearly separated on the basis of dispersion curves obtained in the frequency-wavenumber space. This information paves way to the idea of developing a modal sensor that is capable of providing experimentally determined dispersion curves that can be expected to lead to a quantum advance in capability for modal identification, and hence for determining a far more accurate modal signature for various acoustic emission events.
Fully convolutional network-based ultrasonic inversion for multi-layered bonded composites
Authors: Doust M.
Published: March 2023

Abstract. Ultrasonic methods are widely used for the detection and characterisation of defects in multi-layered bonded composites. However, quantitative reconstruction of defects, such as disbonds, which can affect adhesive bond integrity and severely reduce the strength of assemblies, remains challenging. In this work, a supervised full convolutional network (FCN)-based ultrasonic method is used to quantitatively reconstruct defects hidden in multi-layered bonded composites. This proposed method consists of a training process and a predicting process. In the training process, the FCN builds a non-linear mapping from the ultrasound data to the corresponding longitudinal (L-wave) velocity model. In the predicting process, the network obtained from the training process is used to directly reconstruct the L-wave velocity models from the new measured ultrasonic data of adhesively bonded composites. The simulation results show that the FCN-based ultrasonic inversion method has the ability to achieve the accurate quantitative reconstruction of ultrasonic L-wave velocity models of the high contrast defects, which has potential in online detection of multi-layered bonded composites.
The effect of positional instability on the detection of barely visible impact damage in composites using a mobile thermographic inspection robot
Authors: Gray J.
Published: March 2023

Abstract. As the use of composite materials continues to expand within the aerospace domain and elsewhere, the demand for rapid impact damage detection capabilities is also increasing. Line-scan thermography (LST) is a promising inspection modality where a light source focused to a line is swept over a structural component and sub-surface damage is highlighted as a thermal signature detectable via infrared imaging. This paper presents a rapid LST robotic inspection system combining ground-based robotics, advanced infrared imaging technology and dynamic image processing that is capable of achieving detection of barely visible impact damage in composite structures. The robotic system is evaluated experimentally on carbon fibre composite laminate specimens containing synthetic flat-bottom-hole defects, at scan speeds ranging from 25 mm/s to 100 mm/s. A study into the effect of positional instability on the capacity of the inspection system to detect damage is undertaken by introducing controlled perturbations in the robot path. Finite element modelling is also presented and verified against experimental results. Understanding the effect of positional instability on defect detection is important as work progresses towards an aerial drone-based implementation of this inspection capability.

Published: March 2023

The purpose of this study is to investigate the Indonesian Islamic microfinance institutions' (IMFIs) condition, and their strategies to survive and to explore their contribution during the pandemic by combining and synthesizing the result of all previous studies. To achieve that goal, this research uses a systematic literature review method by mining all data available which in addition makes this paper different from other previous works. This enables us to provide a deeper, broader, and more comprehensive understanding of the topic. Google Scholar is set as the database for three reasons. This research found that Indonesian IMFIs are affected by the pandemic and classified into three categories based on the severity of the impact: Severely hit, affected yet stable, and IMFIs that grow during the pandemic. Indonesian IMFIs had in total 6 types of strategies to survive during the pandemic: Active and passive approaches, common and innovative schemes, as well as persuasive and administrative activities. The study also found the contributions of Indonesian IMFIs during the pandemic and classified them into two categories financial and non-financial contributions. This research is unique by delivering comprehensive non-segregated data and well-synthesized condition of IMFIs in entire Indonesia during the pandemic. The results of this study give policymakers a fundamental ground to develop proper policy in fostering IMFIs after the pandemic. IMFI practitioners should also take benefit from the results by mirroring, modifying, or improving the strategies to face future economic turbulences.
DOORWAY models in the inverse problem for a complex vibronic analogue of the fermi resonance
Authors: Kuzmitsky V. A.
Published: March 2023

We solve the inverse problem for the complex Fermi resonance or its vibronic analogue, and to this end we use the matrix XEXt, where E=diag(\Ek\) is a diagonal matrix, Ek are the energies of the observed "conglomerate" of lines, and the intensities of these lines Ik determine the first row of the matrix X, (X1k)2=Ik k=1,2,...,n,n≥3. Hamiltonian matrix of the direct model, HDIR, whose parameters are the energies of pre-diagonalized "dark" states, Ai, and the matrix elements of their coupling to the "bright" state, Bi, (i=1,2,...,n-1), is obtained after the diagonalization of the XEXt block, which belongs to the "dark" states. We show that Hamiltonian matrix with the single doorway state (DW), HDW1, can be obtained from the matrices HDIR or XEXt by first step of the Householder triangularization, i.e. by similarity transformation with a reflection matrix constructed by quantities Bi or Di=(XEXt)1,i+1. For the energy of the first DW1 state, g1, and the matrix element of its coupling to the "bright" state, w1, the use of the Householder transformation gives: g1=Sigman-1i=1B2iAi/(Sigman-1j=1B2j)= Sigmank=1E3kIk/Sigmanl=1E2lIl, |w1|=(Sigman-1i=1B2i)1/2= Sigmank=1E2kIk)1/2. In similar way, using the Householder transformation, the Hamiltonians for the models with several doorway states, HDW2,HDW3,...,HDW(n-1), are successively obtained. The Hamiltonian of the DW(n-2) model is represented by a symmetric tridiagonal matrix HDW(n-1), its diagonal elements gi determine the energies of the DW1-,DW2-,...,DW(n-1) states, and the off-diagonal elements wi determine the corresponding coupling between them. Keywords: vibronic coupling, complex vibronic analogue of the Fermi resonance, inverse problem, Householder transformation, doorway models.

Published: March 2023

In the case of coherent interaction with a medium of extremely short light pulses (ESPs) having a carrier frequency and harmonic shape (when the pulse durations are shorter than the population relaxation times T1 and polarization relaxation time T2 of the medium), electromagnetically induced gratings (EMIGs) of the population difference, which have a pronounced harmonic dependence on the coordinates, may appear in it. These structures can occur when pulses do not overlap or overlap in the medium. Recently, the possibility of obtaining unipolar electromagnetic pulses in the optical and adjacent ranges of non-harmonic shape, for example, rectangular and triangular, with a duration less or comparable to the duration of the extremely-short pulse in this range, has attracted interest. In this work, using the numerical solution of the system of Maxwell-Bloch equations, we study EMIG formation by rectangular attosecond pulses in a two-level resonant medium. The possibility of inducing an EMIG of a non-harmonic shape in the form of light-induced channels microresonators, (microcavities) with a size of the order of the wavelength of the resonant transition of the medium, whose parameters can be controlled, for example, by the amplitude of the incident pulses, is shown. It has been suggested that it is possible to create an EMIG of a predetermined non-harmonic shape only in the general case of using unipolar pulses. Keywords: attosecond pulses, unipolar pulses, rectangular pulses, electromagnetically induced gratings, polarization waves, light-induced microresonators.

How Natural Language Processing Can Aid With Pulmonary Oncology Tumor Node Metastasis Staging From Free-Text Radiology Reports: Algorithm Development and Validation
Authors: Puts Sander , Nobel Martijn , Zegers Catharina , Bermejo Iñigo , Robben Simon , Dekker Andre
Published: March 2023

Background

Natural language processing (NLP) is thought to be a promising solution to extract and store concepts from free text in a structured manner for data mining purposes. This is also true for radiology reports, which still consist mostly of free text. Accurate and complete reports are very important for clinical decision support, for instance, in oncological staging. As such, NLP can be a tool to structure the content of the radiology report, thereby increasing the report’s value.

Objective

This study describes the implementation and validation of an N-stage classifier for pulmonary oncology. It is based on free-text radiological chest computed tomography reports according to the tumor, node, and metastasis (TNM) classification, which has been added to the already existing T-stage classifier to create a combined TN-stage classifier.

Methods

SpaCy, PyContextNLP, and regular expressions were used for proper information extraction, after additional rules were set to accurately extract N-stage.

Results

The overall TN-stage classifier accuracy scores were 0.84 and 0.85, respectively, for the training (N=95) and validation (N=97) sets. This is comparable to the outcomes of the T-stage classifier (0.87-0.92).

Conclusions

This study shows that NLP has potential in classifying pulmonary oncology from free-text radiological reports according to the TNM classification system as both the T- and N-stages can be extracted with high accuracy.
Multilevel Classification of Users’ Needs in Chinese Online Medical and Health Communities: Model Development and Evaluation Based on Graph Convolutional Network
Authors: Cheng Quan , Lin Yingru
Published: March 2023

Background

Online medical and health communities provide a platform for internet users to share experiences and ask questions about medical and health issues. However, there are problems in these communities, such as the low accuracy of the classification of users’ questions and the uneven health literacy of users, which affect the accuracy of user retrieval and the professionalism of the medical personnel answering the question. In this context, it is essential to study more effective classification methods of users’ information needs.

Objective

Most online medical and health communities tend to provide only disease-type labels, which do not give a comprehensive summary of users’ needs. The study aims to construct a multilevel classification framework based on the graph convolutional network (GCN) model for users’ needs in online medical and health communities so that users can perform more targeted information retrieval.

Methods

Using the Chinese online medical and health community “Qiuyi” as an example, we crawled questions posted by users in the “Cardiovascular Disease” section as the data source. First, the disease types involved in the problem data were segmented by manual coding to generate the first-level label. Second, the needs were identified by K-means clustering to generate the users’ information needs label as the second-level label. Finally, by constructing a GCN model, users’ questions were automatically classified, thus realizing the multilevel classification of users’ needs.

Results

Based on the empirical research of questions posted by users in the “Cardiovascular Disease” section of Qiuyi, the hierarchical classification of users’ questions (data) was realized. The classification models designed in the study achieved accuracy, precision, recall, and F1-score of 0.6265, 0.6328, 0.5788, and 0.5912, respectively. Compared with the traditional machine learning method naïve Bayes and the deep learning method hierarchical text classification convolutional neural network, our classification model showed better performance. At the same time, we also performed a single-level classification experiment on users’ needs, which in comparison with the multilevel classification model exhibited a great improvement.

Conclusions

A multilevel classification framework has been designed based on the GCN model. The results demonstrated that the method is effective in classifying users’ information needs in online medical and health communities. At the same time, users with different diseases have different directions for information needs, which plays an important role in providing diversified and targeted services to the online medical and health community. Our method is also applicable to other similar disease classifications.

Authors: Baldofski Sabrina , Kohls Elisabeth , Efe Zeki , Eckert Melanie , Saee Shadi , Thomas Julia , Wundrack Richard , Rummel-Kluge Christine
Published: March 2023

Background

Mental crises have high prevalences in adolescence. Early interventions appear to be highly important to diminish the risk of the deterioration, recurrence, or chronification of symptoms. In recent years, various providers have started offering live chat support in psychological crises. The messenger-based psychological counseling service krisenchat aims to support young people in crises and, if necessary, provide a recommendation for a referral to the health care system or to seek further help from a trusted adult person.

Objective

This study aimed to investigate the impact of using the counseling service of krisenchat on the further help-seeking behavior of young people, and to identify associated factors of further help-seeking.

Methods

This longitudinal study analyzed anonymous data from 247 individuals who used krisenchat between October 2021 and March 2022, and received a recommendation for further help-seeking. An online survey directly after the chat assessed the perceived helpfulness of the chat and well-being after the chat. After 4 weeks, further help-seeking, facilitators and barriers to help-seeking, and self-efficacy were assessed in an online follow-up survey.

Results

The most frequently recommended services or persons to seek further help from included a psychotherapist or social psychiatric service (75/225, 33.3%), a school psychologist or school social worker (52/225, 23.1%), and the user’s parents (45/225, 20.0%). Of the 247 users, 120 (48.6%) indicated that they contacted the recommended service or person, and of these, 87 (72.5%) stated that they already had an appointment (or talk) with the respective service or person or that an appointment (or talk) was scheduled. The most frequently reported facilitators for further help-seeking were mental health literacy (54/120, 45.0%), improvement of self-efficacy (55/120, 45.8%), and symptom recognition (40/120, 33.3%). In users not displaying further help-seeking behavior, the most frequent barriers included stigmatization (60/127, 47.2%), lack of mental health literacy (59/127, 46.5%), need for self-reliance and autonomy (53/127, 41.7%), and negative family beliefs regarding help services (53/127, 41.7%). Subgroup comparisons indicated significantly higher levels of self-efficacy in users displaying further help-seeking behavior than in those not displaying further help-seeking behavior. Both subgroups did not differ in gender, age, recommended service or person, chat topics, perceived helpfulness, and well-being.

Conclusions

The findings of this study indicate that children and young adults receiving counseling on krisenchat benefit in terms of seeking further help. Further help-seeking seems to be associated with higher levels of self-efficacy.

Exploring How Virtual Reality Could Be Used to Treat Eating Disorders: Qualitative Study of People With Eating Disorders and Clinicians Who Treat Them (Preprint)
Authors: Bould Helen , Kennedy Mari-Rose , Penton-Voak Ian , Thomas Lisa May , Bird Jon , Biddle Lucy
Published: March 2023

BACKGROUND

Immersive virtual reality (VR) interventions are being developed and trialed for use in the treatment of eating disorders. However, little work has explored the opinions of people with eating disorders, or the clinicians who treat them, on the possible use of VR in this context.

OBJECTIVE

This study aims to use qualitative methodology to explore the views of people with eating disorders, and clinicians who treat them, on the possible use of VR in the treatment of eating disorders.

METHODS

We conducted a series of focus groups and interviews with people with lived experience of eating disorders and clinicians on their views about VR and how it could potentially be used in the treatment of eating disorders. People with lived experience of eating disorders were recruited between October and December 2020, with focus groups held online between November 2020 and February 2021; clinicians were recruited in September 2021 and interviewed between September and October 2021. We took a thematic approach to analyzing the resulting qualitative data.

RESULTS

We conducted 3 focus groups with 10 individuals with a current or previous eating disorder, 2 focus groups with 4 participants, and 1 with 2 participants. We held individual interviews with 4 clinicians experienced in treating people with eating disorders. Clinicians were all interviewed one-to-one because of difficulties in scheduling mutually convenient groups. We describe themes around representing the body in VR, potential therapeutic uses for VR, the strengths and limitations of VR in this context, and the practicalities of delivering VR therapy. Suggested therapeutic uses were to practice challenging situations around food-related and weight/appearance-related scenarios and interactions, to retrain attention, the representation of the body, to represent the eating disorder, for psychoeducation, and to enable therapeutic conversations with oneself. There was a substantial agreement between the groups on these themes.

CONCLUSIONS

People with lived experience of eating disorders and clinicians with experience in treating eating disorders generated many ideas as to how VR could be used as a part of eating disorders treatment. They were also aware of potential limitations and expressed the need for caution around how bodies are represented in a VR setting.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Shin Heeseong
Published: March 2023

Objectives This study was conducted to explore issues that should be considered important in realizing the educational content of the elementary school time expression achievement standards newly established in the 2022 Korean language curriculum.. Methods First, in order to clarify the orientation of elementary school time expression education in the 2022 Korean language curriculum, the 2007 and 2015 Korean language curriculum and the 2022 Korean language curriculum were compared. In addition, in order to explore the issues of educational content development, the upper category of time expression, grammar element achievement standards, were analyzed in textbooks that were previously implemented. Finally, elementary school Korean textbooks were also analyzed to illustrate language materials that can be used for time expression education. Results Through curriculum analysis, this study confirmed that the orientation of time expression education in the 2022 Korean language curriculum was significantly different from that in the 2007 Korean language curriculum. In particular, the 2022 Korean language curriculum focused on “language as use, language dynamics, and various aspects of language” and emphasized “discourse and context.” In addition, I argued that time expression education should be implemented with an appropriate hierarchy between height expression and passive expression education through textbook analysis. In addition, the possibility that elementary school time expression education can be linked to literature or reading/writing was confirmed. Specifically, it was exemplified that time expression also contains an expression effect in texts that can be treated at the 5th grade level of elementary school. Conclusions In the 2022 Korean language curriculum, elementary school time expression education should be implemented in delicate consideration of its orientation, hierarchy, and connection. In addition, in order for elementary school time expression education to be implemented as intended, research on learners' use of time expression is necessary.

Data collection was conducted through a survey from April 2, 2018 to December 16, 2019. SPSS 26 and PROCESS macro v4.0 was used for frequency analysis, descriptive statistics, mean comparison, correlation analysis, and mediating effect analysis. The PROCESS macro simple mediation model(No. 4) presented by Hayes (2013) was used for mediating effect verification. Results 53.8% of patients who experienced moderate or more stress, 57.9% of patients who experienced mild or more depression (20.9% of moderate or more), and 10.4% of patients had suicidal ideation. Suicidal ideation was significantly higher in the patients of moderate or higher stress than in the patients of low stress. Suicide ideation was significantly higher in the patients with severe depressive symptoms than in the patients without depressive symptoms. All variables showed a positive correlation. Depression was found to significantly mediate the effect of stress on suicidal ideation. The indirect effect of the pathway of stress to suicidal ideation through depression was statistically significant, but the direct effect was not significant. Conclusions Stress management and depression screening is important for preventing suicide and improving mental health in diabetic patients. So Psychosocial interventions such as Stress management and depression screening need to be included in diabetes education counseling.

INTRODUÇÃO:A Síndrome Respiratória Aguda Grave (SRAG) doença causada pelo coronavírus (SARS-COV-2), por se tratar de uma doença altamente contagiosa e com alto nível de mortalidade, muitas pessoas a fim de se prevenir, ou mesmo tratar da doença por conta própria acabaram que por maioria das vezes se automedicando sem orientação correta de um médico, farmacêutico e/ou profissional da saúde capacitado. Sugerindo que não há somente uma preocupação sobre o aumento da automedicação entre os medicamentos controlados, mas sim também aqueles que possuem sua venda livre, deixando claro a importância da abordagem do tema e as definições sobre novas estratégias de saúde. METODOLOGIA: Trata-se de uma pesquisa de caráter baseada em revisão de literatura de forma narrativa com o tema abrangendo a automedicação e uso irracional de medicamentos durante a pandemia de Covid-19. DESENVOLVIMENTO: Esses dados mostram que a influência para a automedicação durante a pandemia pôde ser evidenciada em diferentes locais e situações. CONCLUSÃO: Devem ser promovidas novas estratégias pelos profissionais da saúde, principalmente farmacêuticos como aulas, palestras e "lives" auxiliando a população no uso racional de medicamentos, também deve haver investimento em estudos sobre o tema para levantar os possíveis efeitos adversos que essa automedicação pode estar trazendo aos longos dos anos.
Plataforma de estudos para banana verde ( musa spp. AAA ): isolamento, caracterização e polimerização e preparação de filmes baseado em amido

Estudos já foram desenvolvidos usando a banana para extração de amido. Entretanto, há poucas informações disponíveis sobre as propriedades do amido proveniente dos frutos verdes e frescos e de produtos obtidos com esta fonte amido. OBJETIVO: Aprimorar técnicas para extração do amido proveniente do fruto da banana verde, caracterização do amido extraído; preparação e caracterização de filmes hidrogelatinosos baseado no amido da banana verde. MÉTODOS: A extração do amido foi realizada por maceração aquosa da banana verde cortada e triturada seguida de flotação, tamização e liofilização do fruto. A caracterização do amido foi feita calorimetria exploratória diferencial (DSC) e microscopia eletrônica de varredura (MEV). O filme baseado em amido foi produzido através das dispersões poliméricas do amido de banana verde e alginato de sódio, seguida da adição de polióis (glicerina e PEG 400). A dispersão hidrogelatinosa dos polímeros adicionada dos polióis foi estendida em placa de vidro, seca em fluxo de ar, na temperatura ambiente e sob luz ultravioleta. As propriedades dos filmes foram caracterizadas por testes físicomecânicos, físico-químicos e morfológicos. RESULTADOS: Com o processo de extração utilizado neste trabalho, foi possível obter um rendimento de 11,93% de farinha de banana verde. Analisando as diferentes formulações propostas, cada uma apresentou suas propriedades em função da relação de massas dos polímeros e da massa molar dos polióis. A formulação II apresentou maior plasticidade, quando comparada as outras formulações I e III, característica essa observada através dos testes físico-mecânicos (tração e perfuração), os quais são influenciados pela resistência das cadeias poliméricas. Os testes físico-mecânicos (resiliência e relaxação) são influenciados pela massa molar dos polióis. Neste caso, as propriedades da formulação III foi melhor quando comparado com as demais. CONCLUSÃO: Com os resultados obtidos podemos sugerir algumas possíveis aplicações para as formulações II e III. Sendo que para a formulação II, devido as suas propriedades plásticas, poderia ser utilizada como filme de revestimento de embalagens. Já o filme da formulação III poderia ser indicada para o desenvolvimento de curativos não oclusivos.

The effect of political connection on corporate tax avoidance: The moderating role of accounting information quality
Authors: Alsmady Ahnaf Ali
Published: March 2023

This study examines the relationship between the political connection and tax avoidance in all Jordanian market companies, the relationship between accounting information quality and tax avoidance, and the moderating effect of accounting information quality between the political connection and tax avoidance relationship. The sample data of the study includes 206 companies, with a total of 2266 observations from the period from 2008 to 2018. The results indicated that the political connection positively correlates with tax avoidance, which is supported (Jensen & Meckling, 1976). The results of this study also indicated a significant negative association between accounting information quality and tax avoidance. Moreover, the moderating effect of accounting information quality on the political connection and tax avoidance relationship indicated a significant negative association with tax avoidance. Thus, the study supported the agency theory that governance mechanisms such as accounting information quality function led to the reduction of agency problems and reduce information asymmetry. The study finding supported Ward et al.’s (2009) argument and suggested that accounting information quality plays a substitute role rather than a complementary role in mitigating the agency problem. The outcomes of this study could assist the policymaker and companies in the importance of accounting information quality in disciplining political involvement in the Jordanian market.
