Citation Culture in the Scientific Text and Verification of Borrowings
Authors: Ivanova E. N. , Sus I. V. 
Published: January 2024

The scientific library historically serves the purposes of education, assists scientific research and integration of information into the body of knowledge. Without the qualitative maintenance of these auxiliary processes, the development of science is impossible. The library retains the status of a keeper of verified and systematized knowledge. In modern conditions, the process of searching and integrating information is simple and accessible. However, freedom and simplicity of obtaining facts and using various tools to compile integral language constructions entails a number of negative effects, including illegal borrowing, falsification and irresponsible use of text generation systems for scientific publications. The purpose of the article is to analyze the problems of citation culture changes caused, among other things, by the emergence of new technologies for artificial text generation. The main provisions of the article are based on the observation and experience of examining scientific manuscripts in order to detect illegal borrowings accumulated by a group of specialists in the Russian State Library over the past decade. This activity is not limited solely by the instrumental detection of plagiarism, but it is also focused on comparison of various citation practices in scientific papers. The problems of citation analysis, the influence of citation culture on the process of research verification are considered. Special attention is paid to the tools for artificial text generation that are actively included in the practice of writing academic texts.
Chemical Instability Induced Wettability Patterns on Superhydrophobic Surfaces
Authors: Chen Tianchen , Chen Faze 
Published: January 2024

Chemical instability of liquid-repellent surfaces is one of the nontrivial hurdles that hinders their real-world applications. Although much efforts have been made to prepare chemically durable liquid-repellent surfaces, few attentions have been paid to exploit the instability for versatile use. Herein, we propose to create hydrophilic patterns on superhydrophobic surface by taking advantage of its chemical instability induced by acid solution treatment. Superhydrophobic Cu(OH)2 nanoneedles covered Cu plate that shows poor stability towards HCl solution (1.0 M) is taken as an example. Results show that 2.5 min of HCl solution exposure leads to the etching of Cu(OH)2 nanoneedles and partial removal of self-assembled fluoroalkyl silane molecular layer, resulting in the wettability transition from superhydrophobocity to hydrophilicity, and the water contact angle decreases from ~160° to ~30°. Hydrophilic dimples with different diameters are then created on the superhydrophobic surfaces by depositing HCl droplets with different volumes. Afterwards, the hydrophilic dimple patterned superhydrophobic surfaces are used for water droplet manipulations, including controlled transfer, merging and nanoliter droplets deposition. The results thereby verify the feasibility of creating wettability patterns on superhydrophobic surfaces by using their chemical instability towards corrosive solutions, which broadens the fabrication methods and applications of functional liquid-repellent surfaces.

On the Influence of Fine Particle Migration and Deposition on Gas Hydrate Production: Insights from the First Trial Production in the South China Sea
Authors: Fan Zejin , Xu Tianfu , Xin Xin , Yuan Yilong , Zhu Huixing 
Published: January 2024

Summary
As a promising alternative energy source with vast reserves, the primary challenge in exploiting natural gas hydrates (NGHs) lies in achieving long-term safety and efficiency. Several production tests conducted globally have demonstrated that the production of solid particles is one of the main factors contributing to this issue. However, most studies on assessing NGH production capacity have overlooked this phenomenon and its impact on production performance, potentially compromising the accuracy of simulation results. Therefore, this study aims to quantitatively analyze the impact of fine particle migration and deposition on gas production by numerically examining the first NGH production test conducted in the Shenhu area of the South China Sea (SCS). Through comparison of simulation results with the reconstructed gas production curve, the model was calibrated and enabled an explanation of unique gas production performance during field testing. It is found that the deposition of solid particles reduced the gas production rate by nearly an order of magnitude during the initial stage of exploitation. Long-term simulation results indicate that only the three-phase layer (TPL) remains partially unobstructed and serves as the primary source of gas production in later stages. Sensitivity analysis reveals that both depressurization and particle control strategies exert significant effects on particle migration, which in turn affects gas production. Specifically, the increase in depressurization amplitude does not necessarily lead to improved gas production behavior beyond a certain threshold (approximately 6 MPa). This study illustrates the inherent trade-off between preventing particle production and increasing gas production, highlighting the need for a safe and efficient production scheme that strikes a balance between these two objectives. Based on the current study, it is preliminarily recommended to maintain a depressurization amplitude of approximately 6 MPa with a maximum depressurization rate of 3 MPa/d and ensure a fine particle filtration ratio of no less than 95%.
A Comprehensive Assessment of the Integration of Solvent and Steam for the Extraction of Bitumen Through the Development of Novel Process Models
Authors: Hoque Mustakimul , Oni Abayomi Olufemi , Kumar Amit 
Published: January 2024

Summary
Solvent-steam bitumen extraction technology has the potential to reduce energy consumption and greenhouse gas (GHG) emissions. It is based on gravity drainage, wherein a steam and vaporized solvent mixture is used to extract bitumen from a reservoir. This can reduce the environmental impact compared with processes that use only steam for bitumen extraction [i.e., steam-assisted gravity drainage (SAGD)]. No techno-economic analysis of solvent-steam extraction has been made available in the public domain. In this study, a process simulation model was developed to assess costs. A capacity of 25,000 B/D of bitumen was considered with hexane as the solvent. Sensitivity and uncertainty analyses were conducted to assess how the supply cost of bitumen produced with diluent (dilbit) changes with changes in input parameters. The supply cost for the base case scenario is 55.5 CAD/bbl at a 10% internal rate of return (IRR). The scale factor was estimated to be 0.80, which suggests that oil production will be economically viable on a large scale. Capital cost, solvent price, and transportation and blending cost affect the supply cost. The most probable supply cost range is 53.0–65.4 CAD/bbl at a 90% confidence interval. The results also indicate that dilbit supply costs from the solvent-steam process are economically attractive compared with the current oil price.
In-Situ Hydrogen Production from Natural Gas Wells with Subsurface Carbon Retention
Authors: Gillick Stuart R. , Babaei Masoud 
Published: January 2024

Summary
There is a critical need to balance economic prosperity, energy security, and environmental protection. Instead of the conventional production of methane (or CH4), these valuable energy reserves can be exploited in a climate-beneficial way. Exploiting (not producing) methane eliminates the carbon value chain and the associated damage these greenhouse gases (GHGs) cause to the climate. When no carbon is produced to the surface, carbon capture requirements become significantly reduced, and their huge budgets are better used elsewhere.
This paper discusses the viability of a wellbore natural gas gasification process, within a downhole completion tool, that converts methane wells into hydrogen (or H2) production wells. The process-generated carbon is simultaneously captured downhole, reinjecting the carbon dioxide (or CO2) into the surrounding geology and potentially gaining reservoir enhanced oil recovery (EOR) as a bonus. The proposed process is for natural gas fields and not for use in the gasification of heavy oils (which is covered by other “combustion type” reservoir management processes performed deep within the reservoir geology).
The multiple revenue streams created by the process, together with process energy, feedstock (methane), and cost savings, make it climate-positive and financially viable. This provides a net-zero win-win that is mutually beneficial for the natural gas industry and the environment. Without enormous technical effort, competitive use of commodities, and huge capital costs, it could be possible to convert the natural gas industry directly into a hydrogen and carbon capture industry.

Published: January 2024

Abstract

Background:
The creation of breast cancer practice guidelines requires careful management of conflicts of interest (COIs). However, limited evidence is available regarding the specific landscape and fraction of financial relationships between pharmaceutical companies and the authors of The Japanese Breast Cancer Society Clinical Practice Guidelines for Breast Cancer,edition 2022 (JBCS2022).
Methods:
Using payment data publicly disclosed by major pharmaceutical companies in Japan, this study analysed the personal payments made to the authors of JBCS2022 between 2016 and 2020. We performed descriptive analyses on the payment data.
Results:
Of 149 JBCS2022 authors, 115 (77.2%) received at least one personal payment from pharmaceutical companies totaling $3,828,455 between 2016 and 2020. The average and median payment amounts per author were $25,772 (SD: $58,197) and $2,761 (IQR: $322‒$15,828), respectively. The total annual payments per JBCS2022 authors between 2016 and 2019 increased from $588,054 in 2016 to $967,802 in 2019. The JBCS2022 chairperson and vice-chairperson received $246,936 (4th highest) and $216,744 (5th highest) over the five years. More than 60% of personal payments to the JBCS2022 authors were not declared by the authors as they were below the declaration threshold set by the Japanese Breast Cancer Society. However, nine authors undeclared personal payments summing $594,615 even though these payments were higher than the thresholds.
Conclusion:
This study demonstrated that the majority of the Japanese breast cancer guideline authors received personal payments from the pharmaceutical companies. Furthermore, the majority of payments were not declared due to the less transparency COI policy.

Abstract

The addition of precursors, like tyrosine (Tyr), can increase the biomass and specialized metabolites production in plant cell suspensions. There is a need of natural compounds with inhibitory activity against α-amylase and α-glucosidase to decrease the intestinal absorption of simple carbohydrates. It has been previously reported that soluble melanins from the Randia echinocarpa fruit inhibit the enzymatic activity of α-glucosidase. Thus, the objective of this study was to analyze the metabolomic profiles of R. echinocarpa cell suspensions when treated with different concentrations of Tyr and to assess the inhibitory activities of the cell extracts against α-amylase and α-glucosidase. Methanolic extracts (1 mg/mL) of R. echinocarpa cell suspensions inhibited the activity of α-amylase similarly to acarbose at 50 µM. Nevertheless, no inhibition of α-glucosidase by the extracts was observed. Further purification of the methanolic extracts is required to prevent antagonist effects of the compounds. Four specific chemical profiles were determined by Hierarchical Cluster and Principal Components Analysis. Galactose metabolism and starch/sucrose metabolism were among the main modulated metabolic pathways. Molecular docking showed that compounds Tyr_100 and 200 treatments had an estimated free binding energy of -2.4 to -5.6 kcal/mol and can interact with key amino acids involve with the catalytic activity of α-amylase. The addition of Tyr to the cell suspensions of R. echinocarpa can be used to produce α-amylase inhibitory extracts.

Abstract

Background
Previous studies have reported that the significant association between serum calcium and mortality substantially in patients, especially among those with intensive care unit (ICU). And In diabetes mellitus, congestive heart failure (CHF) is a significant comorbidity. We aim to evaluate the association between serum calcium levels and in-hospital mortality among patients with diabetes and congestive heart failure.
Methods
The participants in this study were extracted from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. To scrutinize potential associations between serum calcium levels and in-hospital mortality, a comprehensive analysis encompassing multivariate logistic regression, cubic spline function model, threshold effect analysis, and subgroup analysis was performed.
Results
This retrospective cohort study encompassed 7063 patients, among whom the in-hospital mortality stood at 12.2%. In the multivariate logistic regression, adjusted odds ratios (ORs) were contrasted with the reference category Q6 (8.8-9.1 mg/dL) for serum calcium levels and in-hospital mortality. The adjusted ORs for Q1 (≤7.7 mg/dL), Q2 (7.7-8 mg/dL), and Q7 (≥9.1 mg/dL) were 1.69 (95% CI: 1.17-2.44, p = 0.005), 1.62 (95% CI: 1.11-2.36, p = 0.013), and 1.57 (95% CI: 1.1-2.24, p = 0.012) respectively. The dose-response analysis uncovered a U-shaped relationship between serum calcium levels and in-hospital mortality in diabetic patients with heart failure. Subgroup analyses confirmed result stability notwithstanding the influence of diverse factors.
Conclusion
Our investigation revealed a U-shaped correlation between serum calcium levels and in-hospital mortality in diabetes patients with congestive heart failure, pinpointing a significant inflection point at 9.05 mg/dL.
