Research on Feature Extraction and Fault Diagnosis Method for Rolling Bearing Vibration Signals Based on Improved FDM-SVD and CYCBD
Authors: Yang Jingzong
Published: May 2024

In mechanical equipment, rolling bearing components are constantly exposed to intricate and diverse environmental conditions, rendering them vulnerable to wear, performance degradation, and potential malfunctions. To precisely extract and discern rolling bearing vibration signals amidst intricate noise interference, this paper introduces a fault feature extraction and diagnosis methodology that seamlessly integrates an improved Fourier decomposition method (FDM), singular value decomposition (SVD), and maximum second-order cyclostationary blind convolution (CYCBD). Initially, the FDM is employed to meticulously decompose the bearing fault signals into numerous signal components. Subsequently, a comprehensive weighted screening criterion is formulated, aiming to strike a balance between multiple indicators, thereby enabling the selective screening and reconstruction of pertinent signal components. Furthermore, SVD and CYCBD techniques are introduced to carry out intricate processing and envelope demodulation analysis of the reconstructed signals. Through rigorous simulation experiments and practical rolling bearing fault diagnosis tests, the method’s noteworthy effectiveness in suppressing noise interference, enhancing fault feature information, and efficiently extracting fault features is unequivocally demonstrated. Furthermore, compared to traditional time–frequency analysis methods such as EMD, EEMD, ITD, and VMD, as well as traditional deconvolution methods like MED, OMEDA, and MCKD, this method exhibits significant advantages, providing an effective solution for diagnosing rolling bearing faults in environments with strong background noise.
A Quantitative Precipitation Estimation Method Based on 3D Radar Reflectivity Inputs

Published: May 2024

Quantitative precipitation estimation (QPE) by radar observation data is a crucial aspect of meteorological forecasting operations. Accurate QPE plays a significant role in mitigating the impact of severe convective weather. Traditional QPE methods mainly employ an exponential Z–R relationship to map the radar reflectivity to precipitation intensity on a point-to-point basis. However, this isolated point-to-point transformation lacks an effective representation of convective systems. Deep learning-based methods can learn the evolution patterns of convective systems from rich historical data. However, current models often rely on 2 km-height CAPPI images, which struggle to capture the complex vertical motions within convective systems. To address this, we propose a novel QPE model: combining the classic extrapolation model ConvLSTM with Unet for an encoder-decoder module assembly. Meanwhile, we utilize three-dimensional radar echo images as inputs and introduce the convolutional block attention module (CBAM) to guide the model to focus on individual cells most likely to trigger intense precipitation, which is symmetrically built on both channel and spatial attention modules. We also employ asymmetry in training using weighted mean squared error to make the model concentrate more on heavy precipitation events which are prone to severe disasters. We conduct experiments using radar data from North China and Eastern China. For precipitation above 1 mm, the proposed model achieves 0.6769 and 0.7910 for CSI and HSS, respectively. The results indicate that compared to other methods, our model significantly enhances precipitation prediction accuracy, with a more pronounced improvement in forecasting accuracy for heavy precipitation events.

Published: May 2024

Microcystins (MCs), toxins generated by cyanobacteria, feature microcystin-LR (MC-LR) as one of the most prevalent and toxic variants in aquatic environments. MC-LR not only causes environmental problems but also presents a substantial risk to human health. This study aimed to investigate the impact of MC-LR on APCmin/+ mice, considered as an ideal animal model for intestinal tumors. We administered 40 µg/kg MC-LR to mice by gavage for 8 weeks, followed by histopathological examination, microbial diversity and metabolomics analysis. The mice exposed to MC-LR exhibited a significant promotion in colorectal cancer progression and impaired intestinal barrier function in the APCmin/+ mice compared with the control. Gut microbial dysbiosis was observed in the MC-LR-exposed mice, manifesting a notable alteration in the structure of the gut microbiota. This included the enrichment of Marvinbryantia, Gordonibacter and Family_XIII_AD3011_group and reductions in Faecalibaculum and Lachnoclostridium. Metabolomics analysis revealed increased bile acid (BA) metabolites in the intestinal contents of the mice exposed to MC-LR, particularly taurocholic acid (TCA), alpha-muricholic acid (α-MCA), 3-dehydrocholic acid (3-DHCA), 7-ketodeoxycholic acid (7-KDCA) and 12-ketodeoxycholic acid (12-KDCA). Moreover, we found that Marvinbryantia and Family_XIII_AD3011_group showed the strongest positive correlation with taurocholic acid (TCA) in the mice exposed to MC-LR. These findings provide new insights into the roles and mechanisms of MC-LR in susceptible populations, providing a basis for guiding values of MC-LR in drinking water.

Despite significant strides in vaccine research and the availability of vaccines for many infectious diseases, the threat posed by both known and emerging infectious diseases persists. Moreover, breakthrough infections following vaccination remain a concern. Therefore, the development of novel vaccines is imperative. These vaccines must exhibit robust protective efficacy, broad-spectrum coverage, and long-lasting immunity. One promising avenue in vaccine development lies in leveraging T-cells, which play a crucial role in adaptive immunity and regulate immune responses during viral infections. T-cell recognition can target highly variable or conserved viral proteins, and memory T-cells offer the potential for durable immunity. Consequently, T-cell-based vaccines hold promise for advancing vaccine development efforts. This review delves into the latest research advancements in T-cell-based vaccines across various platforms and discusses the associated challenges.

Published: May 2024

Deformation, as the most intuitive index, can reflect the operation status of hydraulic structures comprehensively, and reasonable analysis of deformation behavior has important guiding significance for structural long-term service. Currently, the health evaluation of dam deformation behavior has attracted widespread attention and extensive research from scholars due to its great importance. However, given that the sluice is a low-head hydraulic structure, the consequences of its failure are easily overlooked without sufficient attention. While the influencing factors of the sluice’s deformation are almost identical to those of a concrete dam, nonuniform deformation is the key issue in the sluice’s case because of the uneven property of the external load and soil foundation, and referencing the traditional deformation statistical model of a concrete dam cannot directly represent the nonuniform deformation behavior of a sluice. In this paper, we assume that the deformation at various positions of the sluice consist of both overall and individual effects, where overall effect values describe the deformation response trend of the sluice structure under external loads, and individual effect values represent the degree to which the deformation of a single point deviates from the overall deformation. Then, the random coefficient model of panel data is introduced into the analysis of sluice deformation to handle the unobservable overall and individual effects. Furthermore, the maximum entropy principle is applied, both to approximate the probability distribution function of individual effect extreme values and to determine the early warning indicators, completing the assessment and analysis of the nonuniform deformation state. Finally, taking a project as an example, we show that the method proposed can effectively identify the overall deformation trend of the sluice and the deviation degree of each measuring point from the overall deformation, which provides a novel approach for sluice deformation behavior research.

Suatu algoritma perencanaan jalur bersifat asimptotik optimal jika dapat menjamin bahwa akan menghasilkan solusi optimal jika diberikan waktu yang memadai. Algoritma perencanaan jalur yang dapat memberikan solusi optimal sangat penting dalam banyak aplikasi robotik. Penelitian ini bertujuan untuk mengusulkan algoritma perencanaan jalur baru yang bersifat asimptotik optimal. Metode yang digunakan adalah dengan meningkatkan algoritma probabilistic road map (PRM) melalui tiga strategi. Strategi pertama adalah menggunakan teknik pembangkitan sampel berbasis informasi. Strategi kedua adalah area pencarian dimulai dari subset ellipsoid yang berukuran kecil dahulu. Strategi ketiga adalah melakukan perbaikan jalur menggunakan proses wrapping. Algoritma yang diusulkan ini dinamakan algoritma wrapping-based informed PRM (WIPRM). Selanjutnya, performansi algoritma WIPRM dibandingkan dengan algoritma PRM, informed rapidly-exploring random tree* (RRT*), dan informed PRM. Hasil pengujian menunjukkan bahwa algoritma WIPRM dapat membangun jalur yang optimal untuk semua scenario pengujian. Waktu komputasi yang dibutuhkan algoritma WIPRM untuk membangun jalur optimal lebih baik daripada algoritma informed RRT* dan informed PRM. Dengan demikian, algoritma WIPRM berpotensi untuk diimplementasikan dalam berbagai sistem robotik yang membutuhkan algoritma perencanaan jalur yang optimal seperti mobil otonom, unmanned aerial vehicles (UAV), maupun autonomous underwater vehicles (AUV).

Association of mobile health applications usage with eating behaviour and physical activity among young adults in Malaysia
Authors: Wei Wong Ying , Chng Lau Zhi
Published: May 2024

Mobile health applications (mHealth Apps) are useful technology for personal health management. However, evidence in health improvement is lacking in mHealth Apps usage with eating behaviour and physical activity (PA) in Malaysia. This study aims to investigate the association between mHealth Apps usage with eating behaviour and PA among young adults with different Body Mass Indices (BMI) in Malaysia. A cross-sectional study was conducted. 280 samples were recruited using convenience sampling. An online questionnaire comprised of sociodemographic characteristics, anthropometry measurements, mindful eating behaviour questionnaire, International Physical Activity Questionnaire (IPAQ), and acceptance of mHealth Apps use were distributed. Among the 280 respondents (78.2% female, 18–28-year-old, BMI=21.5±3.79kg/m2), 22.1% were mHealth Apps users. Underweight respondents had the highest mindful eating behaviour score (2.84±0.25), while lowest in obesity Class II (2.57±0.06). Majority of the respondents (68.6%) were not practicing sedentary lifestyle (sitting<8hours). Underweight and obesity Class I respondents were inactive, whereas normal weight and overweight were moderately active. Besides, there is a significant mean difference between mHealth Apps usage with eating behaviour (p=0.048), but not PA level (p=0.134) and sedentary behaviour (p=0.759). The six motivating factors that significantly (p<0.05) influence the acceptance of mHealth Apps usage were: perceived usefulness, perceived ease of use, social influence, facilitating conditions, self-efficacy, and behavioural intention to adopt. The mHealth Apps usage is associated with eating behaviour but not physical activity. Our findings suggested potential for related stakeholders to promote mHealth Apps targeting in young adults to improve health outcome.
Espiritualidade de pacientes em tratamento oncológico
Authors: Macaringue Nilza Emílio de Jesus , Saranholi Taís Lopes
Published: May 2024

Introdução: A espiritualidade é uma tendência inata em direção a Deus ou a uma Força Superior, que surge de nossa busca por sentido e transcendência de nossas vidas. Trata-se de uma construção que envolve “fé” e “sentido”. Fé é crer numa forca transcendental superior. Não se identifica necessariamente com Deus, nem se vincula necessariamente com a participação em rituais de uma determinada religião, está relacionada a ligação com essa forca ou espírito superior que é o componente essencial da experiência espiritual, vinculada com o sentido. Objetivo: Avaliar o nível de espiritualidade dos pacientes que estão em tratamento de quimioterapia. Metodologia: Estudo descritivo transversal com a utilização da Escala de índice de espiritualidade, utilizada para avaliar os três maiores domínios da religiosidade (religiosidade organizacional, religiosidade não organizacional e religiosidade intrínseca ou espiritualidade). Após aprovação pelo Comitê de Ética, a coleta foi realizada com os pacientes adultos, maiores de 18 anos, que estiveram em tratamento no Ambulatório de Oncologia de um hospital terciário do interior de São Paulo que aceitaram participar do estudo. Resultados: Foram entrevistados 55 pacientes, onde foi evidenciado que a maioria dos participantes demonstraram uma preocupação acerca de sua espiritualidade, colocando em prática suas crenças no seu cotidiano. Considerações finais: Identificamos que a maioria dos pacientes acreditam numa força maior que ajuda a aceitação e superação/conformidade com a doença por meio da própria fé, ou seja, daquilo que acreditam e aderem muito bem ao tratamento. A espiritualidade são o sustento e a certeza da vida transformada para um bem físico e espiritual auxiliando em todo o processo do tratamento oncológico.

A diabetes mellitus tipo 2 (DM2), uma condição crônica caracterizada pela resistência à insulina e pela deficiência relativa de insulina, representa um desafio significativo para a saúde pública em todo o mundo. A fisiopatologia do DM2 está intimamente ligada à resistência insulínica, na qual as células do corpo não respondem adequadamente à insulina produzida pelo pâncreas, resultando em níveis elevados de glicose no sangue. Entre os fatores de risco para o desenvolvimento do DM2, destacam-se a obesidade, a falta de atividade física, a dieta pouco saudável e a predisposição genética. O diagnóstico da DM2 geralmente é feito por meio da avaliação dos níveis de glicose no sangue em jejum e do teste de tolerância à glicose oral. Uma vez diagnosticado, o tratamento farmacológico visa principalmente controlar os níveis de glicose no sangue, muitas vezes incluindo medicamentos como metformina, sulfonilureias, inibidores da dipeptidil peptidase-4 (DPP-4) e agonistas do receptor de GLP-1. No entanto, o tratamento não farmacológico desempenha um papel crucial e pode incluir mudanças no estilo de vida, como dieta saudável, exercícios físicos regulares e perda de peso. Embora a DM2 seja historicamente associada a adultos mais velhos, seu aumento está sendo observado em crianças, principalmente devido ao aumento da obesidade infantil. Isso requer uma abordagem especializada no diagnóstico e tratamento, levando em consideração as necessidades específicas dessa população. Além disso, a DM2 em crianças pode acarretar complicações a longo prazo, incluindo doenças cardiovasculares, neuropatias, retinopatias e disfunção renal. Por fim, a DM2 representa um desafio multifacetado para os sistemas de saúde em todo o mundo, exigindo uma abordagem holística que inclua não apenas o tratamento farmacológico para controlar a glicemia, mas também intervenções não farmacológicas para abordar os fatores de risco modificáveis, bem como uma atenção especial ao diagnóstico e tratamento em populações vulneráveis, como crianças.

Este artigo tem como objetivo realizar uma revisão sistemática da produção bibliográfica referente a eficácia do tratamento cirúrgico e suas indicações como terapêutica do quadro clínico de otite média com efusão na população pediátrica.  Após formular a frase de pesquisa, foram realizadas buscas na base de dados Medline, sendo utilizados os seguintes descritores: Otitis Media with Effusion, Middle Ear Effusion, Secretory Otitis Media e Serous Otitis Media. Foram incluídos ensaios clínicos e ensaios clínicos randomizados que apresentavam dados que versavam diretamente sobre as intervenções cirúrgicas da otite média com efusão e foram analisados os resultados obtidos nas avaliações. Os resultados indicaram que a inserção de tubos de ventilação combinada com a adenoidectomia resultou em menor recorrência do quadro em comparação com a inserção do tubo de ventilação de forma isolada. Além disso, observou-se que a inserção do tubo de ventilação em crianças com otite média com efusão persistente não apresentou efeito benéfico na qualidade de vida geral, mas evidências indicaram um desfecho positivo na saúde funcional relacionada à dificuldade auditiva nesta população. Por fim, observou-se que nas crianças com fissura palatina que passaram por reparo no palato mole e que permaneceram com o quadro de otite média com efusão, a inserção do tubo de ventilação deve ser considerada. A análise dos estudos destacou a complexidade das decisões clínicas em relação às intervenções cirúrgicas para o quadro descrito, considerando fatores como recorrência, qualidade de vida e características individuais dos pacientes.

Published: May 2024

O café é uma bebida que está presente na vida quotidiana de muitas pessoas, o que é mais importante por causa das características particulares das variáveis microeconómicas e demográficas que influenciam as preferências de consumo no México. Os níveis de consumo de café no nosso país não são comparáveis aos de outros países produtores, por exemplo, os brasileiros consomem café de qualidade numa proporção quatro vezes superior à dos mexicanos, enquanto os países importadores mostram um crescimento constante da procura de café. Da situação acima descrita surge a presente investigação com o objetivo de identificar as variáveis microeconómicas e demográficas com maior influência nas preferências de consumo de café no México, a fim de identificar opções para aumentar o seu consumo, pois esta análise de regressão foi elaborada utilizando dados relativos ao período de 2000 a 2018. A metodologia aplicada permitiu estimar uma expressão algébrica multivariada que relaciona os principais fatores para caracterizar cada nível de consumo do produto em estudo. Este modelo permitiu identificar que as preferências de consumo de café no México estão atualmente principalmente relacionadas com o preço do café e o preço do açúcar, assim como com o rendimento per capita. Os resultados obtidos neste estudo levam a concluir que as preferências de consumo de café no Mexico são influenciadas por aspectos monetários.

Published: May 2024

A rã-touro (Lithobates castebeianus) é uma espécie de anuro invasora introduzida no Brasil visando à criação comercial. Oferecer anestesia e analgesia para anfíbios representa um desafio considerável para a maioria dos profissionais de saúde animal. O eugenol vem se tornando muito popular nos últimos anos, e age por meio da inibição dos impulsos nervosos. A cetamina tem ação dissociativa, agindo no córtex cerebral, levando o paciente a um estado cataléptico, incapaz de responder voluntariamente a estímulos físicos. O presente trabalho teve como objetivo avaliar a eficiência e segurança da utilização do eugenol associado ao cloridrato de cetamina, por meio das respostas comportamentais, no período trans e pós-anestésico, em um exemplar de Lithobates catesbeianus, durante um exame clínico para coleta de material biológico na Clínica de Pequenos Animais do Centro Universitário de Barra Mansa. O paciente estava em jejum há aproximadamente 24 horas, e foi trazido dentro de um aquário com capacidade de 5 litros. Na avaliação clínica, o animal não apresentou alterações visíveis de acordo com o padrão da espécie. Aos 65 minutos após o início do protocolo anestésico, o paciente apresentou as características condizentes com o plano anestésico ideal. Após a coleta do sangue, houve a tentativa de avaliação dos parâmetros cardiológicos via monitor multiparamétrico. O paciente não apresentou sinais de incômodo e insuficiência respiratória durante o procedimento. Os valores dos parâmetros cardiológicos foram inconclusivos através da avaliação via monitor, sendo definidos apenas pela auscultação cardíaca via Doppler. O paciente apresentou frequência cardíaca de 55 bpm a 50 bpm. Na avaliação da cavidade oral via otoscópio digital, a mesma se apresentou saudável, íntegra e sem alterações. Aos 95 minutos após o início do procedimento, o paciente foi colocado em um segundo aquário de recuperação, e começou a realizar movimentos de retorno aos 140 minutos após o início do procedimento. A recuperação do animal foi gradativa, porém eficaz, demonstrando a eficácia do protocolo anestésico selecionado para a obtenção de material biológico, e confirmando a segurança, viabilidade e não toxicidade do eugenol associado ao cloridato de cetamina para o paciente anfíbio.
RES COGITANS DAN RES EXTENSA SEBAGAI SUBSTANSI PEMBENTUK RUANG DAN WAKTU DALAM TERANG RASIONALISME DESCARTES
Authors: Maia Januario Sergio Viera Demelo
Published: May 2024

Wacana tentang ruang dan waktu merupakan isu yang selalu menjadi polemik di kalangan banyak filsuf dan ilmuwan hingga saat ini. Mereka mencoba merumuskan ruang dan waktu secara subyektif. Karena sejatinya keberadaan setiap makhluk tidak akan pernah lepas dari segala macam dikotomi yang ada baik secara spasial maupun non-spasial. Rene Descartes, salah satu filsuf rasionalisme, mengemukakan pandangannya tentang ruang dan waktu yang berangkat dari konsep substansi. Konsep substansi itu sendiri dimaknai sebagai sesuatu yang berdiri sendiri tanpa bantuan apapun. Tujuan dari penelitian ini adalah untuk memahami dengan baik sekaligus membuka cakrawala berpikir dalam mengetahui dan memaknai keberadaan setiap makhluk dan segala aktivitasnya yang ada baik secara spasial maupun non-spasial. Penulisan jurnal ilmiah ini menggunakan metodologi pendekatan kualitatif-deskriptif dengan menggunakan studi pustaka. Sumber bacaan yang digunakan kemudian dikaji berdasarkan hubungannya dengan kajian fenomena yang dibahas dalam kerangka filsafat. Descartes dengan pemikirannya yang cemerlang telah membangun konsep rasionalitas yang sangat mengagumkan, terlihat dalam adagiumnya yaitu Cogito Ergo Sum yang digunakannya sebagai metode dalam mencari kepastian tentang pengetahuan yang mutlak. Melalui adagiumnya, Descartes kemudian dirangsang untuk berpendapat tentang ruang dan waktu yang bertitik tolak dari substansi. Substansi ini kemudian dibagi menjadi dua sifat utama oleh Descartes yaitu (Res Cogitans) merupakan substansi jiwa yang memiliki sifat spiritual dan tidak eksis secara spasial. Sedangkan (Res Ekstensa) adalah zat materi yang memiliki sifat ekspansif, dan ada secara spasial, atau selalu membutuhkan ruang. Dari dua substansi inilah yang membuat ruang dan waktu ada dalam terang rasionalisme Descartes.

Background: Worm infection is one of the health problems in Indonesia. Worm infections can disrupt nutrient requirements, hinder growth, intellectual development, and affect the immune system, making the body susceptible to other diseases. Selenium is a micronutrient with great potential to influence the immune system. The mechanism of action of selenium includes antioxidant activity, protecting against oxidative damage, maintaining the integrity of the intestinal mucosa, and anti-apoptotic function in the large intestine. Selenium can enhance the host's immune response by increasing the activity of Alternative Activated Macrophages (AAM), which are the main macrophages in fighting intestinal parasitic worms.  Research Objective: To determine the relationship between worm infections and selenium intake. Research Method: Analytical research using a cross-sectional approach. Sampling was done using total sampling technique on elementary school children in the Tabaringan Health Center working area in Makassar City, aged 7-9 years.  Research Results: The frequency distribution of positive worm infections was 22.2%, equivalent to 8 samples, and negative worm infections were 77.8%, equivalent to 28 samples. Adequacy of selenium intake in the samples showed 16.7% inadequacy, equivalent to 6 samples, and 83.3% adequacy, equivalent to 30 samples. The analysis of the relationship between worm infections and selenium intake yielded a P-value = 0.151. Conclusion: There is no relationship between worm infections and selenium intake in children in the Tabaringan Health Center working area in Makassar City.
