An intelligent hybrid deep learning model for rolling bearing remaining useful life prediction

ABSTRACT Remaining Useful Life (RUL) prediction of rolling bearings is one of the intricate and important issues for equipment intelligent maintenance and health management. Various machine learning models and methods have been applied to rolling bearing RUL prediction. However, a single model cannot effectively extract state information and obtain accurate prediction results, and its generalisation is not stable under the condition of small sample data. Therefore this paper proposes an intelligent hybrid deep learning model for achieving accurate RUL prediction of rolling bearings. Firstly, the one-dimensional vibration signal is transformed into the corresponding two-dimensional time-frequency diagram via Continuous Wavelet Transform (CWT). Secondly, the diagram is input into a Multilayer Perceptron (MLP) consisting of a basic three-layer feed-forward network to obtain a one-dimensional feature vector. And lastly, the obtained feature vector is input into an integrated model based on Deep Autoregressive and Transformer to produce the probability distribution and obtain the prediction results of rolling bearing RUL. Extensive experiments on two rolling bearing datasets show that the proposed model outperforms six other comparative models in extracting bearing fault features and predicting bearing RUL, which demonstrates that the proposed model can effectively extract bearing fault features and accurately predict bearing remaining useful life.

Preventability of injury-related morbidity & mortality at four hospitals in Cameroon: A systematic approach to trauma quality improvement.

Adverse events reviews are a fundamental component of trauma quality improvement (QI) that facilitate the correction of systemic issues in care. Although injury-related mortality in Cameroon is substantial, to our knowledge, opportunities for QI have not been formally assessed. Thus, a formal review of adverse events in Cameroonian trauma patients was implemented as a first step toward identifying targets for systems modification. A QI committee composed of multidisciplinary experts at four hospitals in Cameroon was formed to review adverse events including deaths among trauma patients from 2019 to 2021. Events were discussed at newly established morbidity and mortality conferences and committee meetings to identify contributing factors and overall preventability. During 50 meetings, 95 adverse events were reviewed, including 58 deaths (61%). Other adverse events were delays in diagnosis/treatment (22%) and surgical site infections (17%). Overall, 34 deaths (59%) were classified as preventable, 21% potentially preventable, and 21% not preventable. Over half (52%) of the 46 preventable or potentially preventable deaths occurred in the emergency department (ED); while brain injury (57%), respiratory failure (41%), and hemorrhage (39%) were the most frequent physiologic factors associated with mortality. Contributory factors identified include lack of a structured approach to patient management, absence of continuous training for personnel, and locally adapted protocols. Basic improvements in evaluation and management of life-threatening issues in the ED can significantly reduce the high rate of preventable trauma-related deaths across Cameroon. Formal trauma QI methods can be utilized in low-resource environments to determine mortality root causes and identify intervention targets.

Management of Speech and Hearing in Low-Income and Middle-Income Countries: Current Conditions, Problems, Future Directions.

Management of speech and hearing issues in low-income and middle-income countries (LMICs) has been challenging, considering the population size and availability of resources. There is a need to investigate the depth of these challenges and explore the efficacy of strategies to overcome them. This review aimed to delineate the speech and hearing issues in individuals with cleft lip and palate and how they have been managed in the context of LMICs. Keywords were developed based on the objectives of the study to search for literature published during the period 2010 to 2023. Articles from PubMed, Google Scholar, Science Direct, and ProQuest databases were retrieved using appropriate keyword searches. The titles and abstracts were screened to delete the unsuitable articles. Relevant gray literature and hand-searched articles published were also included. The findings are summarized under the following heads in the context of LMICs: incidence and severity of speech and hearing issues, challenges, and barriers in providing speech and hearing services, methods of developing manpower and training, methods of assessing speech and hearing outcomes, service delivery models employed, and the recent advances relating to management of speech and hearing. A wide range of topics revolving around managing speech and hearing issues in individuals with cleft lip and palate has been researched in the context of LMICs. Scattered and fragmented solutions have been provided to overcome the varied challenges in LMICs. The gaps in the literature and the future directions for research have been identified.

The Arterial Anatomy of the Cerebellum—A Comprehensive Review

The cerebellum, a major feature of the hindbrain, lies posterior to the pons and medulla and inferior to the posterior part of the cerebrum. It lies beneath the tentorium cerebelli in the posterior cranial fossa and consists of two lateral hemispheres connected by the vermis. The cerebellum is primarily supplied by three arteries originating from the vertebrobasilar system: the superior cerebellar artery (SCA), the anterior inferior cerebellar artery (AICA), and the posterior inferior cerebellar artery (PICA). However, variations of the cerebellar arteries may occur, such as duplication of the SCA, SCA creating a common trunk with the posterior cerebral artery, triplication of the AICA, and agenesis of PICA, amongst others. Knowledge of the arterial anatomy of the cerebellum is crucial, as inadequate blood supply to this region can result in diminished motor functioning, significantly impacting the quality of life for patients. The present study demonstrated the importance of adequate anatomical knowledge of the arteries supplying the cerebellum. The PubMed and Embase databases were searched to gather articles on the anatomical characteristics and variations of the arterial supply of the cerebellum. It is the most comprehensive and up-to-date review available in the literature. The possible variations of these vessels may be clinically silent or present with clinical symptoms such as neurovascular compression syndromes of the cranial nerves and aneurysms. With a comprehensive understanding of the cerebellar arterial system, physicians can enhance their diagnostic and treatment capabilities, ultimately leading to more effective management of cerebellar vascular-related issues and other neurological deficits.

General practitioner and practice nurses perspectives on implementation of the 75+ health assessment: Implications for dementia care and well-being.

The uptake of the health assessment for persons aged 75 years and older (75 + HA) remains low. Repeat assessments provide an opportunity to identify areas of change in cognitive function which may mark the onset of dementia. We aimed to explore general practitioner (GP) and practice nurse experiences of implementing the 75 + HA with a focus on clinical considerations for dementia care. An interpretative qualitative study involving interviews with 15 GPs (female = 11, male = 4) and 5 practice nurses (all female). Data were analysed using an inductive thematic approach. The majority of GPs (n = 11) worked in metropolitan settings and four GPs worked in regional settings across NSW. All participants worked in separate clinics, except for two GPs and one practice nurse who worked within the same metropolitan clinic. Distinct themes emerged regarding participants experiences of implementing the 75 + HA for patients with dementia: (1) negotiating aged care is complex and facilitated by a comprehensive assessment; (2) implementing work practices that support the 75 + HA in patients with cognitive decline; and (3) variations in follow up of findings and implications for care. The 75 + HA provides an opportunity for monitoring and acting on emergent physical and cognitive health changes. Increased engagement and support towards implementing the 75 + HA, particularly in the context of dementia, may facilitate the instigation of interventions. While some participants in this study were confident with identifying and managing cognitive decline, the majority relied on geriatricians to confirm dementia diagnosis and refer to community support services. We suggest the need for greater initiatives and clinical guidelines to assist GPs in the identification and management of cognitive decline. From a nursing perspective, this study highlights the valuable role of nurses towards assessment and management of issues raised in the health assessment for persons aged 75 years and older. However, more resources are needed to enable nurse time for adequate follow-up care.

Oral health in obese children common findings, prevention, treatment, and outcome

Childhood obesity is a significant global public health issue, closely linked to various oral health challenges, including dental caries, periodontal disease, and malocclusion. Obese children are more prone to these dental problems due to dietary habits that include high sugar and carbohydrate intake, poor oral hygiene practices, and systemic inflammation. This review explores the common oral health issues faced by obese children and emphasizes the importance of preventive strategies and tailored treatment approaches. Preventive measures include promoting healthy dietary habits, improving oral hygiene practices, and ensuring regular dental check-ups. Dietary modifications, such as reducing the intake of sugary snacks and beverages, play a crucial role in preventing tooth decay and other dental problems. Educating children and caregivers about proper brushing and flossing techniques and the use of fluoride toothpaste and dental sealants further supports oral health. Regular dental visits allow for early detection and management of dental issues, with professional cleanings, fluoride treatments, and appropriate restorative and periodontal therapies being integral components of care. The outcomes of these comprehensive treatment strategies are generally positive, leading to improved oral health and overall quality of life for obese children. Multidisciplinary collaboration among healthcare providers, including dentists, pediatricians, and nutritionists, is essential to develop effective care plans that address both obesity and oral health. This integrated approach ensures that obese children receive holistic care that promotes lifelong healthy habits, reducing the risk of future dental and systemic health problems. The review underscores the necessity of a concerted effort to address the intertwined issues of obesity and oral health in children, highlighting the potential for significant health improvements through targeted prevention and treatment strategies.

The author emphasizes the significance of fostering collaboration among academia, government, and civil society in order to establish clinical sociology as an institutionalized field and effectively tackle urgent societal issues.

Achieving sustainable development goals for mental health and gender equality through work-life balance and emotional intelligence

Purpose The purpose of this study is to investigate the relationship between work-life balance and the mental health of Indian managers and to explore the moderating role of emotional intelligence (EI) and gender. Design/methodology/approach Work-life balance scale (Hayman 2005), Mental Health Inventory (Viet and Ware, 1983) and EI scale (Wong and Law, 2002) were administered to 202 (102 males and 100 females) Indian managers. Based on the Conservation of Resource theory, a theoretical model has been designed and hypotheses were tested by descriptive, correlation and moderation analysis. Findings The results of this study indicated that work-life balance is positively correlated with psychological well-being and mental health, while negatively correlated with the psychological distress of managers. EI has emerged as a potential moderator that positively influences the relationship between work-life balance and the mental health of managers. At the same time, gender did not show any moderating effect. Research limitations/implications This research has theoretical, practical as well as social implications. Practical implications This study is aligned with SDG 3 and SDG 5 of the UN Sustainable Development Goals 2023. This paper provides valuable inputs in promoting mental health at the workplace and formulating gender-neutral work-life balance policies and programs in Indian organizations. Social implications This study is aligned with SDG 3 (Health and well-being) and SDG 5 (Gender equality) of the UN Sustainable Development Goals 2023. Originality/value This study is an empirical research paper backed by a sound theoretical framework, which addresses the work-life balance and mental health issues of managers and highlights the positive role of EI in managing their personal and professional lives in a low gender-egalitarian Indian work–family culture.

Evidence of contingency factors related to financial management in state secretariats in the northern region of Brazil

This research aims to highlight the contingency factors influencing financial management in governmental entities. To achieve this goal, a descriptive, qualitative methodology was adopted, with data collection via individual electronic surveys sent to employees of different secretariats within a Brazilian state. The theoretical framework identified the following contingency variables: Environment, Structure, Technology, Information Technology, and Strategy. The results indicate that Contingency Theory (integration of contingency factors) impacts financial management, with Strategy being the only contingency variable showing interference in financial management when analyzed separately. Thus, the analyzed secretariats align with regulations, addressing managerial issues related to Environment, Structure, Technology, and Information Technology factors.

Oral Health Implications of Obstructive Sleep Apnea: A Literature Review.

Obstructive sleep apnea (OSA) is a prevalent sleep disorder characterized by repeated episodes of partial or complete obstruction of the upper airway during sleep. While the systemic implications of OSA are well documented, the dental consequences are less frequently discussed yet equally significant. This review aims to elucidate the oral health impacts of OSA, emphasizing the importance of interdisciplinary care. A comprehensive literature search was conducted across several databases to identify studies examining the relationship between OSA and various oral health parameters. The review included observational studies, clinical trials, and systematic reviews published in English up to January 2024. OSA was significantly associated with heightened risks of bruxism, dry mouth, periodontal disease, temporomandibular joint disorders, palatal and dental changes, and alterations in taste sensation. Mouth breathing associated with OSA was a critical factor in exacerbating xerostomia and dental caries. Furthermore, the systemic inflammation induced by OSA appeared to correlate with the severity of periodontal disease. Patients using oral appliance therapy for OSA also showed notable changes in dental occlusion and required ongoing dental monitoring. The findings underscore the bidirectional relationship between OSA and oral health, highlighting the need for dental professionals to be integral participants in the management of OSA. Early dental evaluation and intervention can contribute to the overall health and quality of life of individuals with OSA. The review advocates for the development of clinical guidelines to facilitate the early identification and management of OSA-related oral health issues within dental practice and encourages a collaborative approach to patient care.

Association of Coronavirus Disease 2019 Vaccination with Facial-Related Neurological Disorders: A Nationwide Retrospective Cohort Study.

Neurological complications after the coronavirus disease 2019 (COVID-19) vaccine administration have been reported. However, the incidence rates of these complications have not been compared in vaccinated and unvaccinated individuals. This study used a nationwide cohort from South Korea to investigate the incidence and prognostic factors of facial-related neurological disorders, such as facial palsy, trigeminal neuralgia, and hemifacial spasms, after COVID-19 vaccination. A population-based cohort design was used to examine data from a randomly selected 50% of the adult population in Seoul, South Korea. Information on demographics, vaccination status, vaccination type, and medical history was collected. The incidence rates and adjusted hazard ratios (aHRs) for facial-related neurological disorders were calculated. This study included 2,482,481 adults, 85.94% of whom were vaccinated. Vaccinated individuals showed a higher incidence of facial palsy, hemifacial spasm, and trigeminal neuralgia than unvaccinated individuals, with significant aHRs of 1.821, 3.203, and 6.621, respectively. Dyslipidemia, female sex, and young age were identified as risk factors for hemifacial spasms and trigeminal neuralgia. This study demonstrates an increased incidence of facial-related neurological disorders after COVID-19 vaccination, particularly among individuals with dyslipidemia and younger women. These findings underscore the need for further investigations into the mechanisms and management of vaccine-related neurological issues.

Policy processes in China: a systematic review of the multiple streams framework

The multiple stream framework (MSF) helps explain why policy makers address some issues but not others. Although the framework was originally developed in the USA, scholars argue that it has universal explanatory power across political systems and have called for applications to authoritarian settings. In response, we conduct a systematic review of China-focused MSF research, including 22 English-language articles and 156 Chinese-language articles. We show an increase in publications and identify education and social policy as the two most studied areas. Based on the reviewed articles, we highlight four key themes pertaining to China’s policy process: the dominance of the political stream, the limited role of the national mood, managerial issues in the problem stream, and stream dependence. In addition to a need to conceptualise and test how these aspects shape policy outputs and outcomes, we argue that, if the framework is to contribute to a better understanding of China’s policy process, future MSF research should not only venture into unexplored policy areas but also ought to be more explicit and transparent in terms of operationalisation and focus more on analysing causal relationships. Other research priorities include comparative and critical analysis of MSF hypotheses in other non-democracies.

Timing determines zooplankton community responses to multiple stressors.

Human activities and climate change cause abiotic factors to fluctuate through time, sometimes passing thresholds for organismal reproduction and survival. Multiple stressors can independently or interactively impact organisms; however, few studies have examined how they interact when they overlap spatially but occur asynchronously. Fluctuations in salinity have been found in freshwater habitats worldwide. Meanwhile, heatwaves have become more frequent and extreme. High salinity pulses and heatwaves are often decoupled in time but can still collectively impact freshwater zooplankton. The time intervals between them, during which population growth and community recovery could happen, can influence combined effects, but no one has examined these effects. We conducted a mesocosm experiment to examine how different recovery times (0-, 3-, 6-week) between salt treatment and heatwave exposure influence their combined effects. We hypothesized that antagonistic effects would appear when having short recovery time, because previous study found that similar species were affected by the two stressors, but effects would become additive with longer recovery time since fully recovered communities would respond to heatwave similar to undisturbed communities. Our findings showed that, when combined, the two-stressor joint impacts changed from antagonistic to additive with increased recovery time between stressors. Surprisingly, full compositional recovery was not achieved despite a recovery period that was long enough for population growth, suggesting legacy effects from earlier treatment. The recovery was mainly driven by small organisms, such as rotifers and small cladocerans. As a result, communities recovering from previous salt exposure responded differently to heatwaves than undisturbed communities, leading to similar zooplankton communities regardless of the recovery time between stressors. Our research bolsters the understanding and management of multiple-stressor issues by revealing that prior exposure to one stressor has long-lasting impacts on community recovery that can lead to unexpected joint effects of multiple stressors.

The rise of passive investing: a systematic literature review applying PRISMA framework

Purpose Passive investing has established itself as the dominant force in the world of professionally managed assets, surpassing the concept of index funds. Its meteoric rise is fueled by investors’ preference for its dual benefits of strong diversification and low cost. A comprehensive study of the economic model, addressed areas and market structure has not yet been conducted, despite the existence of numerous studies on more specific topics. To address this gap, this paper examines 943 articles on passive investing published between 1998 and 2022 in SCOPUS and Web of Science.Design/methodology/approach The study utilizes the most pertinent tools for conducting a systematic review by the PRISMA framework. This article is the result of SLR and extensive bibliometric analysis. Contextualized systematic literature review is used to screen and select bibliographic data, which is then subjected to a variety of bibliometric analyses. The study provides a bibliometric overview of works on passive investment research that are indexed in Scopus and Web of Science. Bibliometrix, VoS Viewer and Cite Space are the tools used to conduct content and network analysis, to ascertain the present state of research, as well as its focus and direction.Findings Our exhaustive analysis yields important findings. One, the previous decade has witnessed a substantial increase in the number of publications and citations; in particular, the inter-disciplinary and international scope of related research has expanded; Second, the top three clusters on “active versus passive funds,” “price discovery and market structures” and “exchange-traded funds (ETFs) as an alternative” account for more than fifty percent of the domain’s knowledge; Third, “Leveraged ETFs (LETFs)” and “environmental, social and governance (ESG)” are the two emerging themes in the passive investing research. Fourth, despite its many benefits, passive investing is not suitable for everyone. To get the most out of what passive investing has to offer, investors, intermediaries and regulators must all exercise sufficient caution. Our study makes a substantial contribution to the field by conducting a comprehensive bibliometric analysis of the existing literature, highlighting key findings and implications, as well as future research directions.Research limitations/implications While the study contributes significantly to the field of knowledge, it has several limitations that must be considered when interpreting its findings and implications. With our emphasis on academic journals, the study analyzed only peer-reviewed journal articles, excluding conference papers, reports and technical articles. While we are confident that our approach resulted in a comprehensive and representative database, our reliance on Elsevier Scopus and Web of Science may have resulted in us overlooking relevant work accessible only through other databases. Additionally, specific bibliometric properties may not be time-stable, and certain common distribution patterns of the passive investing literature may still be developing.Practical implications With this study, it has been possible to observe and chart the high growth trajectory of passive investing research globally, especially post-US subprime crisis. Despite the widespread adoption of passive investing as an investment strategy, it is not a one-size-fits-all proposition. Market conditions change constantly, and it frequently requires an informed eye to determine when and how much to shift away from active investments and toward passive ones. Currency ETFs enable investors to implement a carry trade strategy in their portfolios; however, as a word of caution, currency stability and liquidity can play a significant role in international ETFs. Similarly, LETFs may be better suited for dynamic strategies and offer less value to a long-term investor. Lastly, the importance of investor education cannot be underestimated in the name of the highly diversified portfolio when using passive alternatives, for which necessary efforts are required by regulators and investors alike.Social implications The inexorable trend to passive investing creates numerous issues for fund management, including fee and revenue pressure, which forces traditional managers to seek new revenue streams, such as illiquid and private assets, which also implies increased portfolio risk. Additionally, the increased transparency and efficiency associated with the ETF market indicates that managers must rethink the entire value chain, beginning with technology and the way investments interact. Passive investments have triggered changes in market structure that are still not fully understood or factored in. Active management and a range of valuation opinions on whether a price is “too low” or “too high” provide much-needed depth to a market as it attempts to strike a delicate balance between demand and supply forces, ensuring liquidity at all price points.Originality/value I hereby certify that I am the sole author of this paper and that no part of this manuscript has been published or submitted for publication.

The results of the current study could be considered a potential resource for future research and patient care information.

Practical Applications and Observational Implications of Time-Based Coding for Workers' Compensation Clinical Encounters-A Follow-up to Best Practices in Documenting and Coding High-Value Care in Workers' Compensation Encounters-ACOEM Guidance Statement.

Clinical practices that provide workers' compensation care and other services related to managing work-related illnesses and injuries have long been challenged in receiving appropriate payment for their professional work. The American College of Occupational and Environmental Medicine (ACOEM) has provided excellent guidelines for coding and billing via its various documents that have been provided over the years. However, despite these guidelines, payors have been slow to adopt occupational specific coding guidelines to justify higher professional payment. With the move to a Centers for Medicare & Medicaid Services (CMS)-sponsored time-based coding option in 2011, the occupational and environmental medicine (OEM) clinics have been able to finally not only document but recoup the value of those services that go beyond the simple patient interface, being able to capture those activities that truly provide high value in the management of workers' medical issues.
