Experimental Study on Sand Detection and Monitoring Using Distributed Acoustic Sensing for Multiphase Flow in Horizontal Pipes
Authors: Shetty Rishikesh , Sharma Jyotsna , Tyagi Mayank 
Published: October 2023

Summary
Excessive sand production in wellbores can cause significant damage to the downhole and surface equipment, which could reduce well productivity and cause loss of integrity. Conventional surface sand detectors provide a delayed indication of the onset of downhole sanding events. Additionally, they do not provide definitive information about the zones in the reservoir contributing to sanding. Distributed fiber-optic sensors can address these gaps by enabling real-time downhole monitoring simultaneously across the entire length of the installed fiber in the wellbore.
In this study, we investigate the application of optical fiber-based distributed acoustic sensing (DAS) for real-time monitoring of sand migration patterns, detecting sand ingress location, and estimating sand slip velocity. The sand slip velocity is the difference in the flow velocity of sand particles and fluid velocity in slurry flow caused by drag forces. DAS was acquired on a horizontal experimental surface flow loop at different flow rates and sand ingress conditions for a fixed sand slurry concentration and sand particle size. DAS data were analyzed in the frequency domain using spectrums and spectrograms to investigate the frequency fingerprint of the flowing sand that enabled visualization of sand migration patterns in multiphase flow. Sand flow velocities were estimated using the DAS frequency band energy (FBE) profiles and compared with analytical models of sand transport. A reasonable comparison was observed for all six experimental data sets analyzed in this study. Comparison of results from 28 gal/min and 32 gal/min trials showed higher sand slip velocity at higher flow rates. Different sand ingress locations were detected using DAS spectrum analysis. The results demonstrate the successful application of DAS for in-situ sand monitoring and flow characterization that can enable targeted sand management and remediation.

Abstract

There is a sparsity of information about occupational exposure to pesticides on small-scale farms in developing countries. This study investigates rice growers’ exposure to pesticides due to the use of knapsack/backpack sprayers, a practice which is widespread in developing countries including Malaysia. Pesticide application information was collected from 23 rice growers during November 2020 – March 2021 using personal interviews and questionnaires. The information was used to predict total daily exposure to individual active substances via dermal and inhalation routes during mixing/loading and application activities using selected exposure models. The estimated exposures were assessed against the agricultural operator exposure levels (AOELs) for single active substances, where any exceedance indicates a potential risk to health. The 23 rice growers cultivated 0.6 – 3.8 ha of rice. Pesticides were applied on 3 -13 different days by the different growers with between 1 and 8 compounds applied on individual spray days. Individuals had estimated average daily exposures to single active substance compounds of 4.1x10-3 to 1.3x10-1 mg kg-bw-1 day-1 (4.0x10-3 – 1.3x10-1 and 4.2x10-5 – 5.4x10-2 mg kg-bw-1 day-1 during application and mixing/loading activities, respectively), where dermal exposure constituted 89 – 99.6% of the total exposure. Overall, 25% of all the applications reported by the 23 growers had exposure estimates that exceeded the AOELs, mainly due to the use of highly toxic pesticides, products formulated as wettable powders, and/or growers neglecting to wear gloves whilst handling pesticides. All of these factors can be improved by provision of training and information on selection of pesticide products and application practices. Study findings can be used to target efforts to minimise pesticide risks to health in developing countries.

Published: October 2023

Abstract

Background: Early identification of high-risk individuals with cisplatin-induced nephrotoxicity (CIN) is crucial for avoiding CIN and improving prognosis. In this study, we developed and validated a CIN prediction model based on general clinical data, laboratory indications, and genetic features of lung cancer patients before chemotherapy.
Method: We retrospectively included 696 lung cancer patients using platinum chemotherapy regimens from June 2019 to June 2021 as the test set to construct a predictive model using Absolute shrinkage and selection operator (LASSO) regression, cross validation, and Akaike's information criterion (AIC) to select important variables. We prospectively selected 283 independent lung cancer patients from July 2021 to December 2022 as the validation set to evaluate the model's performance.
Result: The prediction model showed good discrimination and calibration, with AUCs of 0.9217 and 0.8288, sensitivity of 79.89% and 45.07%, specificity of 94.48% and 94.81%, in the test and validation sets respectively. Clinical decision curve analysis suggested that the model has value for clinical use when the risk threshold ranges between 0.1 and 0.9.
Conclusion: Predictive models based on laboratory and demographic variables can serve as a beneficial complementary tool for identifying high-risk populations with CIN.

Published: October 2023

Abstract

Objectives: Experimental studies indicate a role for galectin-1 and galectin-3 in metabolic disease, but clinical evidence from larger populations is limited.
Methods: We measured circulating levels of galectin-1 and galectin-3 in POEM study participants (n=502, all aged 50 years) and characterized the individual association profiles with metabolic markers, including clinical measures, metabolomics, adipose tissue distribution (Imiomics) and proteomics.
Results: Both galectins were associated with fatty acids, lipoproteins and triglycerides including lipid measurements in the metabolomics analysis adjusted for BMI. Galectin-1 was associated with several measurements of adiposity, insulin secretion and insulin sensitivity, while galectin-3 was only associated with fasting insulin levels. Mechanistically, both galectins were associated with inflammatory pathways and FABP4- and 5-regulated triglyceride metabolic pathways. Galectin-1 was also associated with several proteins related to adipose tissue differentiation.
​Conclusions: The similar metabolic association profiles for galectin-1 and -3 indicate overlapping metabolic effects, while the distinctly different associations seen with fat mass, fat distribution, and adipose tissue differentiation markers could suggest a functional role of galectin-1 in obesity. This study indicates that galectin-1 and -3 have metabolic effects in humans.
Impact of climate change beliefs on farm households’ adaptation behaviors: the case of Ivory Coast.
Authors: DESQUITH Louise-Ella Docteur en sciences économiques 
Published: October 2023

Abstract

This paper examines how climate beliefs influence the adaptation decisions of Ivorian farmers. Based on the level of exposure to climate shocks and the type of farming practiced, two regions (Bouaké and Bonoua) were selected for data collection and 658 households were surveyed. Using a multivariate probit model, we analyze the impact of climate beliefs on decisions to implement an adaptation strategy. Our results indicate that the impact of beliefs on adaptation decisions varies according to the region considered. In Bouaké, religious and traditional beliefs, as well as subjective predictions of temperature trends, are the main drivers of farmers' adaptation decisions. In Bonoua, on the other hand, concerns about climate change and confidence in scientific studies on the worsening of CC determine farmers' adaptation decisions. In addition, the results of beliefs about the anthropogenic origin of climate change appear decisive. Policy recommendations are derived from our findings.

Optimizing User Acceptance of AI Agents in Information-Sharing Environments
Authors: Kehat Rebecca , Hirschprung Ron , Alkoby Shani 
Published: October 2023

Abstract

Information-sharing (IS) occurs in almost every action of our daily life. IS holds benefits for its users, but it is also a source of privacy violations. Human users struggle to balance this trade-off between the potential benefits and the resulting costs. This reality calls for Artificial-Intelligence (AI)-based agent assistance that surpasses humans’ bottom-line utility, as shown in previous research. However, convincing an individual to follow an AI agent’s recommendation is not trivial; therefore, the current research goal is establishing trust in the machine. To this end, based on the Design of Experiments (DOE) approach, we developed a methodology that optimizes the user-interface (UI) with a target function of maximizing the AI agent recommendation acceptance. To empirically demonstrate our methodology, we conducted an experiment with eight UI factors and (n=64) human participants acting in a Facebook simulator environment accompanied by an AI-agent assistant. Based on the results, we showed how the methodology can be implemented to optimize the agent’s users’ acceptance. Finally, while our methodology was tested empirically on an IS platform, it could be applied straightforwardly in other domains.

Abstract

The high‑groundwater‑level coal mining areas have a long history of mining and are mainly located in east-central region of China. Subsidence caused by coal mining has several different periods. However, the subsidence change regularity in each periods remains unclear. This study aimed at revealing the subsidence change regularity in high‑groundwater‑level coal mining areas in different periods. Juye mining area was selected for the study, which located in Heze City, Shandong Province, China. Firstly, 54 Sentinel-1A radar satellite images from August 2018 to July 2020 were acquired for this research. The “two-track method” of D-InSAR technology was employed to process of images. Secondly, based on subsidence velocity of 1.7 mm/day, the subsidence process was divided into three periods: initial, active and weakening. Thirdly, elevation data of ground levelling points were used to check the accuracy of subsidence monitoring using Sentinel-1A data. At last, the subsidence change process in different periods was analyzed and the change regularity was summarized. The results are shown as follows: (1) The subsidence characteristics are not obvious in initial period. (2) The subsidence funnel begin to form and the mean maximum subsidence in center is greater than 1400 mm in active period. (3) The subsidence rate and volume gradually decrease and eventually stabilize in weakening period. The results can provide an important basis for land conservation in mining areas.

Abstract

Plant-derived natural products, including those from bryophytes, are particularly advantageous in several aspects, as for antifungal, antibacterial, and anticancer properties. However, the bioactivity potential of secondary metabolites found in the liverwort species Acrolejeunea fertilis (A. fertilis) has not been extensively investigated; moreover, it has limited biomass in nature. An in vitro culture can be a solution for the propagation of A. fertilis. The application of plant growth regulatory substances with various concentrations is expected to increase the growth of A. fertilis. This study aimed to determine the optimum concentration of 2,4-dichlorophenoxyacetic acid and kinetin applied to the gametophyte phase of A. fertilis in vitro culture. This study also aimed to compare the metabolite profile between A. fertilis from nature and in vitro culture condition, using methanol and n-hexane solvent. The compounds in the extracts were identified using gas chromatography-mass spectrometry (GC-MS) also their antioxidant and antibacterial activities. The IC50 values for nature and in vitro extracts were in the range of 58.41–63.10 µg/ml and 111.73–112.10 µg/ml. The total value of phenolic compounds in A. fertilis extracts ranged from 58.51 ± 0.02 µgGAE/g and 272.53 ± 0.02 µgQE/g, respectively. The antibacterial activity revealed inhibition on S. aureus using an n-hexane A. fertilis from nature. Thus, this study highlights the diverse secondary metabolite profiles and bioactivity potential of A. fertilis extracts. These findings have important implications for the development of natural products for medicinal and mass propagation in terms of the potential of A. fertilis as a source of bioactive compounds.

Abstract

Objective
the new inflammation biomarkers has been enrolled to predict risk of several chronic diseases. However, research on biomarkers related to Non-Alcoholic Fatty Liver Disease (NAFLD) wasn’t deep. We aimed to identify the inflammation index most closely associated with NAFLD, explore its trajectory in relation to NAFLD events
Methods
Firstly, through 29123 domestic and 6331 international cross-sectional samples, we utilized random forest analysis to screen out the most potent inflammatory factors associated with NAFLD prevalence. Secondly, through 8524 domestic cohort samples, we utilized Group-based Trajectory Modeling (GBTM) to identify the key inflammatory factor (changes) trajectories. Furtherly, we utilized random survival forest analysis to rank the importance of key inflammatory factor-related trajectories and baseline. And then, we utilized the Cox proportional hazard model to assess the MHR-related trajectory's risk of NAFLD incidence. Finally, we conducted subgroup analysis and interaction analysis.
Results
The prevalence of NAFLD in domestic and international cross-sectional data was 30% and 20% respectively. Random (survival) forest analysis revealed that MHR is the most significant contributor among the five inflammatory factors to the prevalence of NAFLD, and the MHR trajectory is the most prominent indicator among the three MHR-related factors in terms of its contribution to the incidence of NAFLD, in the Chinese cohort. The incidence of new-onset NAFLD gradually increased with the elevation of MHR trajectory (P < 0.05). MHR trajectory had an additive interaction with BMI on the incidence of NAFLD.
Conclusion
A higher MHR trajectory was significantly associated with an increased risk of NAFLD incidence, suggesting that monitoring MHR trajectory over time may aid in identifying pre-NAFLD and NAFLD, particularly in overweight and obese men.
