Published: October 2022

Abstract
Additive Manufacturing technology for innovative tilting pad thrust bearings can combine cleaner production process and performance improvement compared to traditional design. This new solution can also fit form and function of existing components in operation, opening to the possibility of a new kind of bearing upgrade service model.
The new approach, allowing performance improvement, is based on conjugate heat transfer Computational Fluid Dynamic (CFD) simulation of the thrust bearing tilting pad sectors with oil supply definition. The solid pad has been simulated considering a series of micro-channels optimized to enhance pad temperature exchange with surrounding oil flow. Additive manufacturing has been used to realize the complex micro-channel geometry and the bearing has been tested back-to-back with a traditional design. This technology minimizes carbon footprint by reducing bearing size and associated oil flow consumption, at same/higher performance and reliability/availability.
To contain compression system footprint, costs and increase efficiency the new rotor and bearing design has been pushed to higher load and speed. The new generation machines are facing new rotordynamic challenges and compressor OEMs are more and more moving towards rotor bearing integrated design and manufacturing. New manufacturing technologies like additive can help to face the new energy transition challenges and, in the near future, will play a key role. In the present work, a new manufacturing process has been developed leveraging the availability of in-house traditional bearing manufacturing line and new additive manufacturing technology labs. The material and design used allow for traditional babbitting and pad finishing whereas additive technology is opening new geometry boundaries. A first prototype has been tested back-to-back with the traditional design showing, at same load and speed, significant reduction of pad temperature up to 10 °C. The presented solution can fit form and function of existing components in operation opening to the possibility of a new kind of bearing upgrade service model able to enhance between maintenance bearing time or to reduce equipment footprint by increasing bearing specific load and reduce oil flow consumptions up to 20%-30%.
The novelty of the present work was to validate enhanced CFD bearing simulations to unlock additive manufacturing potentials. This opens to the topological optimization of bearing geometry to enhance heat transfer and reduce bearing equipment footprint and oil consumptions. This is particularly suited for energy transition compressor applications.

AbstractThis paper introduces a new sensor analytics application for flow profiling that is based on physics-informed machine learning (ML) techniques. The application was utilized in the interpretation of point and distributed sensor data acquired from a carbonate reservoir in the Middle East and the results enhanced the confidence in the utilization of fiber-based flow monitoring solutions. The application was tested on two data sets: (1) a distributed fiber optic sensing (DFOS) data set acquired during acid stimulation and water injection periods from an injector and (2) a point acoustic sensor data set acquired from an oil producer. In both cases, the output of the application was qualified using independent measurements.A combination of ML and first-principles models has been used to develop the real-time sensor analytics application. Over 1500 data points were acquired in laboratory conditions where flow conditions were simulated. Various ML models were trained on the labelled data from these experiments to provide flow diagnostics for the subject well completion type and those with highest accuracy were selected for development. Independently interpreted production and petrophysical logs were used in the qualification process to validate the interpretation results obtained with the developed sensor analytics technology.The results from both cases agreed with the results from the qualifying measurements. In the first case, the production log and the DFOS measurements were taken under two different injection conditions. Hence, some discrepancies were observed between the two which were explained by the heterogeneity within the reservoir section. In the second case, data from the point acoustic sensor and the production logging (PL) tool were acquired under the same conditions. The flow profiles predicted by the ML model applied on the point acoustic sensor data agreed with the production log.

Abstract
Subsurface data management is one of the prime challenges confronting today's E&P industry. Oil & Gas companies are generating substantial amount of data in E&P operations to achieve their strategic goals. The fact that E&P companies are using multi-vendor technologies makes the case of standard procedures, consistent nomenclature, and data synchronization even more compelling to achieve the uniformity of data and related mnemonics across their databases. This in-turn maximizes the efficiency & potential of existing organizational resources along with facilitating the instant data access & data sharing among common end-users (geologist, petrophysicist, geophysicist etc.).
United Energy Pakistan, formerly known as BP Pakistan, has a hybrid environment of multi-vendor technologies supporting its operation requirement of data and information management and archival. Its assets have a rich heritage, starting nearly four decades ago when an American E&P company, Union Texas Pakistan, initiated operations in Pakistan. Since then, several changes and a shift in ownership several times has resulted challenges to manage the assets and underlying data. Corporate Data Governance and ManagementProject was embarked to address geoscience end user challenges regarding access to validated data and cleaning of working environment. The journey began with a data management maturity assessment few years ago. This helped to identify gaps in the existing data management processes and systems. An integrated roadmap was developed to bridge the gaps with identified digital initiatives and solutions. A vendor neutral and technology agnostic approach was used to perform the site assessment.
A conformance study, prior to the commencement of project, was conducted to assess the "Current State" of G&G Working project databases and to articulate the "Future State" with special emphasis on providing centralized, quality assured and integrated data environment. The study highlighted the key areas of Geoscience working environment that require improvement. Some of the key findings of study indicated huge number of working projects, data dissemination, Lack of Standards, incompleteness, inadequate dataflow mechanism and procedures, data redundancy, and inability of data search and access.

Published: October 2022

Abstract
Background: Our previous study revealed the chemokine CCL22 and its receptor CCR4 are elevated in cervical cancer (CC) tissues. The present study aimed to investigate the potential role of EZH2-induced epigenetic activation of CCL22/CCR4 and caused EMT remodeling in CC.
Methods: We evaluated whether CCL22-CCR4 expression levels could be regulated by EZH2 and subsequently evaluated the mechanism of EZH2 on the CCL22-CCR4. The animal model supported the experimental findings.
Results: CCL22 and CCR4 were significant up-regulated in CC samples compared with normal cervix tissues, and obvious induction of promoter DNA methylation levels of CCL22and CCR4 was shown in CC tissues. Demethylation reactivated the transcription of CCL22 and CCR4. DNMT3A was found to directly bind to the CCL22and CCR4 promoter regions in vitro. Downregulation of the expression of EZH2 in CC cell lines altered DNMT3A expression, induced CCL22and CCR4 promoters’ methylation level as well, and decreased CCL22and CCR4 mRNA expression. An in vivo assay showed that, EZH2 regulated the expression of CCL22/CCR4 components through DNMT3A, consistent with the in vitro results. In EZH2-silenced CC cells, migration was reduced, levels of EMT related markers, including vimentin, slug, snail and β-catenin, were all reduced, and ZO-1 increased. In DNMT3A-silenced CC cells, migration was induced and vimentin, slug, snail and β-catenin were all induced, ZO-1 reduced. Inhibition of CCL22 protein significantly decreased migration of CC cells and vimentin, slug, snail and β-catenin, increased ZO-1.
Conclusions: Overall, EZH2 thus appears to regulate CCL22/CCR4 expression via epigenetic activation, causing EMT process remodeling in CC progression.

Association Between Hours of Work and Subjective Wellbeing. How Do Physicians Compare to Other Professionals?
Authors: Núñez-Elvira Alberto 
Published: October 2022

Abstract
Background: The analysis of wellbeing among physicians has focused on stress, burnout, and job satisfaction but most analyses rely on small and unrepresentative samples. Using self-reported data between 2011/12 and 2014/15 from a large well-established UK dataset - the Annual Population Survey (APS), this study examines the main subjective wellbeing metrics of physicians in the UK and compares with those of other professionals (lawyers and accountants).
Methods: APS is the first survey in the UK that incorporated SWB metrics in April 2011. Since then, the Office for National Statistics have included those metrics in other surveys. The analysis relies on APS data from 2011/12 to 2014/15 and examines the associations between subjective wellbeing variables and hours of work, hourly wages, and underemployment. Estimates are provided for all occupations of interest (pooled model) and then conditioning on each occupation using general linear models (ordinary least squares).
Results: A total of 11,810 respondents are included in the analysis among the four main occupations (primary care physicians – general practitioners in the UK, hospital doctors, lawyers, and accountants) of which 8,011 are salaried workers (67.83%). Physicians are more satisfied and happier with their lives and less anxious than other professionals. Age affects negatively to happiness and satisfaction with their lives (-2.1% and -5.1% respectively) and females are more stressed (10.7%) overall. Incorporating preferences to work more hours (underemployment) physicians’ wellbeing is not affected but those of lawyers and accountants worsens.
Conclusions: Physicians are less anxious, happier, and more satisfied than lawyers or accountants. Total hours of work do not seem to affect SWB for physicians when the variable is the aggregate measure but working more overtime hours is associate with lower wellbeing levels. Working fewer hours than desired (underemployment) is also associated with changes in wellbeing levels. Increasing the hours of work of underemployed physicians could be an inexpensive solution to overcome the alleged shortage of health workers.

Abstract
The world has been facing an increase in various natural hazards. The coastal regions are recognized as one of the most vulnerable due to high population pressure and climate change intensity. Mediterranean countries are one of the most burnable ecosystems in the world, one of the most exposed to pluvial floods, and have the highest erosion rates within the EU. Therefore, the aim of this study was to develop the first multi-hazard susceptibility model in Croatia for Sali settlement (island of Dugi otok). The creation of a multihazard susceptibility model (MHSM) combined the application of geospatial technology (GST) with a local perception survey. The methodology consisted of two main steps: (1) creating individual hazard susceptibility models (soil erosion, wildfires, pluvial floods), and (2) overall hazard susceptibility modeling. Multicriterial GIS analyses and Analytical Hierarchy Process were used to create individual hazard models. Criteria used (32) to create models are derived from very-high-resolution (VHR) models. Two versions of MHSM are created: 1) all criteria with equal weighting coefficients and 2) weight coefficients determined based on a public perception survey. Both models had similar results and reveal moderate susceptibility of Sali to multiple hazards. The public perceives that the research area is the most susceptible to wildfires. The greatest difference between public perception and the GIS-MCDA model of hazard susceptibility is related to soil erosion. However, the accuracy of the soil erosion model was confirmed by ROC curves based on recent traces of soil erosion in the research area. The proposed methodological framework of multihazard susceptibility modeling can be applied, with minor modifications, to other Mediterranean countries.

Abstract
Background. To analyze the impact of the COVID-19 pandemic on mental health hospital admissions, the use of mechanical restraint and number of aggressions to the staff.
Methods. Outcomes in the period from March 14, 2020–December 31, 2020 were compared to the same period in 2019. A multivariate logistic regression analysis was carried out to compare the risk of mechanical restraint during admissions in the two periods, controlling for potential confounding variables.
Results. There was a 30.7% reduction in the number of inpatient admissions with significant changes in the profiles of the patients admitted. There were no differences in the risk of restraint and aggressions. Violence was less frequent as a reason for restraint in the pandemic period, while agitation increased.
Conclusions. The COVID-19 pandemic has had a significant impact on the functioning of the hospitalization ward. Measures introduced during pandemic did not seem to have a meaningful effect on mechanical restraint procedures or violent behavior towards the staff.
Mixing dynamics of droplets levitated using acoustic tweezers: an optical approach
Authors: Honda Kota , Fujiwara Kota , Hasegawa Koji , Kaneko Akiko , Abe Yutaka 
Published: October 2022

Abstract
Acoustic levitation is well-suited to ‘lab-on-a-drop’ contactless chemical analysis of droplets. Rapid mixing is of fundamental importance in lab-on-a-drop platforms and many other applications involving droplet manipulation. Small droplets, however, have low Reynolds numbers; thus, mixing via turbulence is not possible. Inducing interfacial oscillation is effective in this regard, however, the relationship between internal flow and mixing dynamics of droplets remains unclear. Here, we conducted simultaneous optical measurements of the flow field and distribution of fluid components in acoustically levitated droplets. A relationship between internal flow due to interfacial oscillation and mixing of fluid components was revealed, and the effect of kinematic viscosity on the flow characteristics of droplets with interfacial oscillation is discussed. The experimental results were consistent with the theoretical findings. Thus, the internal flow induced by droplet oscillation could enhance droplet mixing. Our findings will be conducive to the application and further development of lab-on-a-drop devices.

Abstract
Background
Waist circumference (WC) is representative of abdominal visceral fat, which is strongly associated with cardiovascular disease (CVD) and its’ outcomes. We aimed to define WC thresholds predicting incident CVD and all-cause mortality within each body mass index (BMI) categories in Tehran Lipid and Glucose Study.
Methods
In this prospective cohort study, a total of 3344 men and 4068 women were followed up for 18 years. Participants were categorized based on BMI into BMI < 25, 25 < BMI < 30, and BMI > 30. The sex-specific WC cut-points within each group were estimated by the maximum value of Youden’s index based on incident CVD and all-cause mortality prediction.
Results
667 and 463 CVD incidents (incident rate 3.1 to 4.5 in men and 1.1 to 2.6 in women per 1,000 person-years within BMI categories) and 438 and 302 mortalities (incident rate 2.1 to 2.7 in men and 1.2 to 1.4 in women per 1,000 person-years within BMI categories) were happened in men and women, respectively. WC thresholds were 82, 95, and 103cm based on incident CVD and 88, 95, and 103cm based on all-cause mortality among men in BMI < 25, 25 < BMI < 30, and BMI > 30, respectively. The respective values for women were 82, 89, and 100cm based on incident CVD and 83, 90, and 99cm based on all-cause mortality in BMI < 25, 25 < BMI < 30.
Conclusion
The BMI-specific WC thresholds given here can give clues to future studies to define more accurate incidence-based WC cut-offs as screening tools to better identify individuals at high risk of developing CVD.

Published: October 2022

Abstract
Background: Screen time refers to the time an individual spends using electronic or digital media devices such as televisions, smart phones, tablets or computers. The purpose of this study was to conduct systematic review to analyze the relevant studies on the length and use of screen time ofschool-agedchildren at home and abroad, in order to provide scientific basis for designing screen time interventions and perfecting the screen use guidelines for Chinese school-agedchildren.
Methods: Screen time related studies were searched on PubMed, EMBASE, Clinical Trials, Controlled Trials, The WHO International Clinical Trials Registry Platform, the Cochrane Central Register of Controlled Trials, CNKI, and Whipple Journal databases from January 1, 2016 to October 31, 2021. Two researchers independently screened the literature and extracted the data, and adopted a qualitative analysis method to evaluate the research status of the length and usageof screen time of school-aged students.
Results: 53 studies were included. The screen time of schoolchildren aged 6 to 14 was 2.77 hours per day, and 46.4% of them had an average screen time ≥2 hours per day. The main uses were TV, computer and games.
Conclusion: Excessive screen time has become a common behavior among children and adolescents around the world. Intervention measures to control children's screen use should be explored in combination with different uses to reduce the proportion of non-essential uses.
Evaluation of stoma-related complications and postoperative Health-related quality of life in patients with rectal cancer underwent low anterior resection following neoadjuvant chemoradiotherapy: protective diverting ileostomy versus transverse colostomy

Published: October 2022

Abstract
Purpose: The choice between loop ileostomy (LI) and loop transverse colostomy (LTC) after low anterior resection (LAR) is still controversial. This study aims to evaluate the prevalence of stoma-related complications for these two categories of diverting enterostomy. Additionally, health-related quality of life for patients received LI was compared to those with LTC.
Methods: From 2014 to 2019, patients who underwent LAR following neoadjuvant chemoradiotherapy were selected initially for the study. All participants received protective diverting LI or LTC. Concrete data of patients’ demographic, surgery and follow-up information were obtained from the constructed database of the hospital. Comparison of patients’ postoperative recovery data was conducted.
Results: 127 and 90 patients received ileostomy versus transverse colostomy respectively. During the mean follow-up time of 37.3±11.2 (17-52) months, 28(12.9%) patients developed stoma-related complications. Compared with patients in LI groups, those received LTC demonstrated longer defecation period after the radical surgery (P=0.006, higher incidence of parastomal hernia (P=0.015) and wound infection (P=0.035). LTC groups displayed a lower incidence of peristomal dermatitis and disturbance of water and electrolyte (P=0.037). LI group showed better feedback on cognitive functioning (P<0.001), body image (P=0.015) and more complaint on dry mouth (P=0.004). LTC group expressed more inconvenience on embarrassment by stoma(P<0.001) and better experience on stool frequency and bags change(P=0.015).
Conclusion: Diverting LI display more rapid intestinal function recovery but higher risk of short-term stoma-related complications caused by high volume of excrement. Patients underwent LI got better cognitive function scale but worse feedback on problems related to stool frequency.
