Published: November 2024

The introduction of generative artificial intelligence (AI) has revolutionized healthcare and education. These AI systems, trained on vast datasets using advanced machine learning (ML) techniques and large language models (LLMs), can generate text, images, and videos, offering new avenues for enhancing surgical education. Their ability to produce interactive learning resources, procedural guidance, and feedback post-virtual simulations makes them valuable in educating surgical trainees. However, technical challenges such as data quality issues, inaccuracies, and uncertainties around model interpretability remain barriers to widespread adoption. This review explores the integration of generative AI into surgical training, assessing its potential to enhance learning and teaching methodologies. While generative AI has demonstrated promise for improving surgical education, its integration must be approached cautiously, ensuring AI input is balanced with traditional supervision and mentorship from experienced surgeons. Given that generative AI models are not yet suitable as standalone tools, a blended learning approach that integrates AI capabilities with conventional educational strategies should be adopted. The review also addresses limitations and challenges, emphasizing the need for more robust research on different AI models and their applications across various surgical subspecialties. The lack of standardized frameworks and tools to assess the quality of AI outputs in surgical education necessitates rigorous oversight to ensure accuracy and reliability in training settings. By evaluating the current state of generative AI in surgical education, this narrative review highlights the potential for future innovation and research, encouraging ongoing exploration of AI in enhancing surgical education and training.

In some libraries, special theater departments were formed to facilitate the search for such literature. Their study is one of the areas of book culture transformation research in social communications of the 19th – 21st centuries. The purpose of this article is to present the results of identification and analysis of “theater departments” in Siberian libraries of the pre-revolutionary period. This study is based on viewing more than two hundred catalogs of Siberian libraries of the 19th – early 20th centuries, which made it possible to identify six of them that had independent theater departments in the pre-revolutionary period. The results are as follows. Six libraries had such departments. Most of them – 4 out of 6 – were city public libraries. For the first time, the quantitative indicators of the theater departments were calculated: the number of titles of books and volumes in them, their place among other departments according to these two criteria. Most of the titles and volumes were in the theater departments of Barnaul and Nerchinsk city public libraries, less than the rest – in Kurgan. The funds of the theater departments contained mainly dramatic works by Russian and foreign authors. The works by domestic playwrights prevailed. The plays by the famous Russian playwright A. N. Ostrovsky were widely presented in these departments. Theatrical periodicals written out by Siberian libraries are listed, among which the magazines “Artist” and “Theater and Art” are the most common. The main areas of interaction between libraries and organizers of amateur performances have been identified, which can be mutually beneficial to modern cultural institutions.

Unlocking biological complexity: the role of machine learning in integrative multi-omics
Authors: Kumar Ravindra , Ruhel Rajrani , van Wijnen Andre J.
Published: November 2024

The increasing complexity of biological systems demands advanced analytical approaches to decode the underlying mechanisms of health and disease. Integrative multi-omics approaches use multi-layered datasets such as genomic, transcriptomic, proteomic, and metabolomic data to understand biological processes much more comprehensively compared to the single-omics analysis and to provide a comprehensive view of cellular and molecular processes. However, these integrative approaches have their own computational and analytical challenges due to the large volume and nature of multi-omics data. Machine learning has emerged as a powerful tool to help and resolve these challenges. It offers sophisticated algorithms that can identify and discover hidden patterns and provide insights into complex biological networks. By integrating machine learning in multi-omics, we can enhance our understanding of drug discovery, disease, pathway, and network analysis. Machine learning and ensemble methods allow researchers to model nonlinear relationships and manage high-dimensional data, improving the precision of predictions. This approach paves the way for personalized medicine by identifying unique molecular signatures for individual patients, which can provide valuable insights into treatment planning and support more effective treatment. As machine learning continues to evolve, its role in multi-omics analysis will be pivotal in advancing our ability to interpret biological complexity and translate findings into clinical applications.

Nitrified Acid Fracturing Treatments in HPHT Carbonate Formations: Results of the Large Campaign in the Middle East
Authors: Bretzer A. , Yudin A. , Nurlybayev N. , Al-Jalal Z. , Faisal M. , Solihin Y. , Sanchez R.
Published: November 2024

Hydraulic fracturing for tight and depleted high-pressure high-temperature (HPHT) gas carbonate reservoirs poses a particular challenge as reservoir pressure is often not sufficient to support post-fracturing flowback. This paper will describe the utilization of nitrogen in the fracturing treatment to guarantee successful flowback of the fracturing fluids.

When depleted wells are stimulated with traditional acid fracturing fluids, nitrogen lifting is required to allow for flowback. Incorporating nitrogen into the treatment itself eliminates the need for this resulting in time and cost reductions as well as more efficient utilization of resources. Since nitrogen is pumped as a gas, specialized high-pressure pumps are required for the operation. In terms of treatment design, one of the benefits of using nitrogen to energize the treatment fluids is its ability to be used in most conventional pumping schedules due to being chemically inert and therefore compatible with a wide range of fluid systems.

Because this type of treatment involves pumping energized fluids, it is important to discuss the additional safety concerns inherent in the operation. Equipment requirements, typical treatment design and fluids, and job execution are also presented. With extensive utilization over the past several years, the benefits and effectiveness of this technique have been clearly proven to outweigh the minor changes in equipment and operational requirements over conventional acid fracturing stimulations. Candidate selection is of particular importance to the success of the treatment, and consideration must be given to the reservoir conditions when evaluating a potential application. Improvements in operational efficiencies compared with traditional completions utilizing nitrogen lifting are also highlighted. Additionally, improved flowback results from the energized fluids have been observed and given per categories of wells reaching up to 48% productivity gains when compared to conventional fracturing technique, mainly in the depleted areas of the formation. The study also provides comprehensive candidate selection guidelines to choose either regular or nitrified acid fracturing techniques based on productivity index analyses.

Although the study focuses on nitrified fracturing treatments in the Middle East, the technique can be widely applied to many tight and depleted carbonate formations worldwide. Therefore, the operational overview, treatment design, and overall field development results presented in the paper will be of significant interest to stimulation professionals throughout the industry.

Due to the impact of the geological nature of the Tengiz field, which is dominated by high fracture areas and has associated drilling challenges such as lost circulation, a first development trial well named as a "High-Pressure Lower Slope Development" (HPLSD) project well was initiated. The well was designed by the engineering team of Tengizchevroil to be horizontal producer with the longest lateral section in Kazakhstan. This paper describes Managed Pressure Drilling (MPD) and Managed Pressure Cementing (MPC) aspects of the HPLSD project.

MPD was utilized on 12 ¼ × 13 ½", 8 ½", and 6" sections to improve drilling performance. The system was used to control bottom hole pressure and manage background gas, it was further applied to minimize loss/gain scenarios and allow drilling through the "narrow" margin between pore and fracture pressures, along with decreasing the wellbore instability and differential sticking risks.

Constant Bottom Hole Pressure (CBHP) technique helped to successfully cement the 7 ¼" liner avoiding any losses of cementing fluid into the wellbore. The primary cementing of the 8 ½" hole section compiled of reservoir embedded with the layers of anhydrite and limestone has been associated with the risks of losing the cement slug, and therefore creating the risk of not achieving adequate cementation. The MPD system helped to successfully run in hole the 7 ¼" liner, cement it and finalize the 6" hole section running the Lower Completion in constant bottom hole pressure mode.

MPD results examined in this paper provide the proof that MPD system is as reliable tool not only for drilling, but also for managed pressure cementing, compensation of swab effect, managing small volumes of influx, and circulating associated gas while drilling. The additional capabilities offered by MPD technology in effectively controlling wellbore pressure profiles has led to MPD tools becoming a commonplace in Tengiz drilling operations.
Using Borehole Image Logs to Refine Reservoir Architecture for Carbonate Reservoir Models, Korolev Field, Republic of Kazakhstan
Authors: Bishop J. W. , Playton T. , Bibolova A. , Correa Mora F. , Sargunanov M. , Hanschitz M.
Published: November 2024

The architecture of carbonate reservoirs can be complex due to depositional profiles with variable, locally steep dips, and to changes in stratal geometries through time resulting from the interplay of accommodation and carbonate sediment production. Capturing this architecture in reservoir models is important for constraining the geometry of flow units and baffles and for distributing reservoir quality. Where seismic interpretation is uncertain or core is limited, borehole image logs can provide valuable information to better constrain architecture.

This study focuses on Korolev Oil Field, a late Paleozoic isolated carbonate platform in the Pricaspian Basin, Republic of Kazakhstan, and illustrates how borehole image logs can be used to refine the interpretation of horizon tops and facies boundaries for input into reservoir models. Bed dips interpreted from image logs provided useful quantitative information, and trends in dip datasets were revealed using plots of cumulative dip azimuth and magnitude. Integration of bed dip data with image log facies, seismic mapping, core description, biostratigraphy, and conventional logs helped identify the orientation of depositional slopes, the boundary between platform and slope facies, and the position of differential compaction related to antecedent platform margins. This updated reservoir architecture has changed the interpretation of facies (slope vs. platform) and horizons to which productive zones in some wells are attributed and has therefore impacted the distribution of reservoir quality in the model. This study underscores the value of commonly under-utilized bed dip interpretations for constraining carbonate reservoir architecture. Integration of bed dip trends from borehole image logs with other available datasets improved the selection of well tops, the interpretation of surfaces, and the position of facies boundaries, all of which are critical static reservoir model inputs.

Uranium is crucial to the nuclear fuel industry, with Kazakhstan providing about 45% of the global supply, mainly through in-situ leaching (ISL) mining methods. ISL involves injecting a leaching agent to dissolve uranium oxides, which are then extracted as a solution. Optimizing acid volumes for uranium extraction while minimizing environmental impact is essential for improving production efficiency. In this paper we introduce a solution using a high-resolution hydrodynamic simulator to model acid injection, enabling a detailed analysis of acid sweep efficiency at well and cell scales. We also developed industry-specific metrics, including pH, the relationship between the cumulative volume of solution injected (L) and the rock mass within a region (S), and acid-to-uranium ratio, for comprehensive evaluation. As proof of concept, the simulated pH of produced solution closely matches measured values, with minor deviations caused by unaccounted acid-rock reactions. The next step is to integrate a reactive transport model to improve chemical reaction accuracy. Custom Python scripts provide flexibility in managing injection schedules and acid concentrations. The framework tracks acid transport from injection to production wells, offering insight into reservoir dynamics. This work enhances uranium mining efficiency while promoting sustainable growth in the industry.

Published: November 2024

In 2021, Tengizchevroil (TCO) initiated a pivotal standardization of business processes, data, and technology in several directions, particularly in asset management and materials management in line with Chevron’s enterprise program. Thus, digital solutions were aimed at boosting competitive performance, increasing reliability, preventing failures, managing risk and minimizing the lifecycle cost of surface assets. The central foundation for successful implementation of these solutions is high-quality data management, achieved through the automation of data clean-up and enrichment procedures using Computer Vision (CV) and Large Language Model (LLM) technologies.

The primary challenge faced was the significant amount of missing data in the existing ERP system. To rectify this historical issue, CV and LLM technologies were employed to reduce costs and enhance quality. The complexity of the project was heightened by the need to convert data from scanned files (PDFs) into a computer-friendly JSON format using a CV tool. The resulting deeply nested JSONs were then parsed into structured datasets and allocated to corresponding objects in the ERP system through a reliable LLM.

Fifteen AI models were trained until the suitable ones were found. As a result, approximately 40,000 rows of data were gathered to enrich relevant attributes and characteristics of surface assets and materials. This innovative approach saved 100 working days for eight data analysts with engineering backgrounds, who typically process 50 attributes per day. Much fruitful work has been done on research to obtain the first results appeared in the ERP system.
Freedom of Choice in the United States: Patient Autonomy is Driving Decision-Making in Bariatric Surgery
Authors: Lutfi Rami , Mitko John , Habib Peter , Chaconas Christen
Published: November 2024

Introduction:
Obesity is a global epidemic affecting over 650 million adults, with bariatric surgery emerging as a potent intervention for achieving long-term weight loss and mitigating associated comorbidities. [1] Among the various surgical options, sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are widely performed in the United States. However, optimal surgical selection remains contentious, especially considering the increasing prominence of patient autonomy in healthcare decisions.
Methods
This prospective study, conducted from May 2021 to May 2022, included adults with obesity who were candidates for SG or RYGB. Patients completed a survey regarding their surgical choices and referral sources before receiving standardized education about both procedures. Patients with diabetes were subsequently presented with an evidence-based calculator predicting individual remission rates for diabetes post-surgery. Choices were compared pre- and post-consultation.
Results
Of the 429 patients surveyed, 74.1% had a pre-determined surgical choice, with SG being preferred by 81.4%. The majority of choices were influenced by internet searches. Post-education, despite a significant proportion of diabetic patients receiving alternate recommendations based on the evidence calculator, only 34% altered their initial choice.
Discussion
Findings indicate that patient decisions regarding bariatric surgery are heavily influenced by non-evidence-based internet sources, with a pronounced resistance to altering choices even when presented with objective data. Notably, perceived safety of procedures appears to outweigh considerations of diabetes remission rates.
Conclusions
The pervasive influence of the internet on surgical decision-making poses challenges for healthcare providers striving to balance patient empowerment with evidence-based recommendations. As patients often arrive with pre-determined surgical options, more effective strategies are needed to navigate these complex dynamics to enhance patient satisfaction and optimize surgical outcomes.

Published: November 2024

This study aims to explore the temporal dynamics of the relationships between problematic social media use(PSMU), self-transcendence values, and school adaptation among college students. Methods: This study employed longitudinal cross-lagged analysis and structural equation modeling to investigate whether there is a mutual influence among PSMU, self-transcendence values, and school adaptation. Additionally, the study explored whether these variables serve as intermediaries in the associations between the other two variables. Results: 2668 students were longitudinally followed up for two-wave.The results indicated PSMU predicted self-transcendence values and school adaptation 6 months later; self-transcendence values predicted PSMU and school adaptation 6 months later; and school adaptation predicted self-transcendence values and PSMU 6 months later. Moreover, each of them plays a mediating role in the association between the other two variables. Conclusions: These results support and expand the Self-worth Theory and Self-determination Theory that there is a bidirectional relationship between PSMU, self-transcendence values, and school adaptation. This result has implications for helping college students adapt to college life and reduce PSMU.

Yet HIVST accessibility and uptake remain limited in Lake Victorias beach communities where HIVST holds promise to address many barriers highly mobile populations of men in fishing communities face. We assessed HIVST knowledge and acceptability among highly mobile fishermen, a high priority population for HIV prevention and treatment, participating in a social network-based study (“Owete”; NCT04772469) to promote HIV testing, prevention, and treatment in Kenya.
Methods
Sixty-five in-depth baseline interviews (IDIs) and two focus group discussions (FGDs) were conducted at study baseline from December 2021 to June 2022 with fishermen, including 30 who were social network-central men recruited as HIVST “promoters” from three fishing communities along Lake Victoria, Kenya. Fishermen were purposively-sampled based on study arm, community and age (18–34 and 35+) for interviews exploring HIVST knowledge, perceived benefits, and concerns. IDIs and FGDs were audio-recorded, translated/transcribed into English and inductively-coded and analyzed by six researchers using a framework approach.
Results
Nearly all participants had heard about HIVST and expressed willingness to self-test. Almost half reported learning about HIVST for the first time through the Owete study. Perceived benefits of self-testing included privacy, convenience, and being able to learn one’s status with the freedom to choose when and where to test, which minimized stigma and work interruptions. Few participants had used HIVST prior to joining Owete, all of whom reported ease of use. Potential barriers to HIVST included fear of HIV-seropositive results, feeling unsure about how to use HIVSTs, and fear of stigma if a HIVST was discovered. Nearly all Owete promoters indicated willingness to distribute HIVST to help their peers know their status. Promoters stressed the importance of approaching HIVST discussions strategically and thoughtfully to garner trust and engagement, and felt they needed training to answer HIVST questions.
Conclusion
While few fishermen had ever used HIVST, this study found high awareness, positive perceptions, and substantial willingness to use and distribute HIVST to other men. The “promoter” model, with known peers engaged in disseminating HIVST information and test kits, shows promise for engaging men in testing.

The pomegranate (Punica granatum L.) has a rich history of cultivation and is renowned for its beneficial properties and nutrient-dense fruits. Native to Central Asia, particularly Iran, Punica granatum has spread to various parts of the world, including Mediterranean countries, Russia, Japan, India, Afghanistan, Pakistan, California, and China. The pomegranate has garnered increasing global interest due to its high nutritional value, as well as its ornamental, industrial, and medicinal benefits. Identifying molecular markers that are less affected by environmental conditions is crucial for measuring genetic diversity among pomegranate cultivars and assisting breeders in selecting and developing genotypes with higher quality and consistency. This study aimed to explore the genetic diversity and stomatal characteristics of nine pomegranate cultivars collected from various locations in Duhok Governorate, Kurdistan Region/Iraq. Genetic diversity was assessed using a combination of molecular methods, including Start Codon Targeted (SCoT) markers, SRAP markers, and the Internal Transcribed Spacer (ITS) gene region, trnG-trnS gene, and 18S–28S rDNA intergenic spacer. The ITS region yielded a product of 700 bp, the trnG-trnS gene was 580 bp, and the 18S–28S rDNA intergenic spacer was 854 bp. Digestion of the trnG-trnS gene with the restriction enzyme HaeIII produced a single amplicon of approximately 490 bp across all samples. The results demonstrated that both SCoT and SRAP markers were effective for analyzing genetic diversity in pomegranates. Additionally, the stomatal structure analysis revealed significant variability among cultivars, with consistent internal structures observed across the cultivars. However, measurements of stomatal components varied depending on the growing location. This study highlights the wide genetic diversity among pomegranate cultivars and the impact of environmental factors on stomatal characteristics.

On January 1, 2024, an Mw 7.5 reverse-fault earthquake occurred along the submarine active faults just offshore of the Noto Peninsula in central Japan. This earthquake is one of the largest inland crustal earthquakes that ever recorded in Japan. We performed inversions of near-field strong-motion waveforms (0.05–0.25 Hz) to investigate the kinematic rupture process of this earthquake. For the inversions, we assumed listric fault planes, where the dip angles are steeper near the seafloor and become gentler with increased depth, based on the location of the submarine fault offsets, the structure at shallow depths revealed by seismic reflection surveys, and the relocated aftershock distribution at deep depths. To constrain our kinematic source model, we also utilized geodetic information published by the Geospatial Information Authority of Japan. We identified that the rupture process had three phases. The first phase was the initial rupture with a small slip of ~ 2 m around the rupture initiation area. After several seconds, the second and third phases, which were the main ruptures, propagated in the southwest and northeast directions, respectively. During the second and third phases, five large slip areas with average slips of 5–6 m significantly contributed to the strong-motion waveforms. By forward-simulating the geodetic data, we found that the rupture at shallow depths included an oblique component close to a right-lateral component and that, in the eastern part of the source region, the rupture transferred from a southeastward-dipping fault to a northwestward-dipping fault. The listric fault with high dip angles at shallow depths is better than a planar fault with a single dip angle for accurately modeling the fault slip near the surface and the coseismic displacement close to the fault trace during the reverse-fault earthquake.

Circoviruses belong to the family Circoviridae, which is classified into two genera, Circovirus and Cyclovirus. Some circoviruses have been identified in various organisms and/or their fecal samples and might be associated with diseases in their hosts. However, few circoviruses are reported in human. Recently, two novel circoviruses, HCirV-1 and HCirV-2, were identified in human through next-generation sequencing and are suspected to be associated with liver diseases, particularly among immunosuppressed patients. They are defined as the species of Circovirus human in the family Circoviridae. Given the potential association of these viruses with liver diseases, as well as their small virion size and possible resistance to inactivation, the presence of both viruses in blood may raise biosafety concerns for plasma derivatives. Therefore, to investigate the prevalence of both new human viruses is essential, which needs a rapid, accurate, and specific assay for the detection and screening of these two viruses. In this study, we developed a duplex HiFi-LAMP assay for simultaneous detection of HCirV-1 and HCirV-2. The assay exhibits high sensitivity with LOD of 64 and 49 copies per 25 µL reaction for HCirV-1 and HCirV-2, respectively. The assay demonstrated a rapid reaction time of 35 minutes while enabling simultaneous detection of both HCirV-1 and HCirV-2. Clinical screening test showed that neither HCirV-1 nor HCirV-2 were detected among 875 patients with infection of HBV, HIV-1 or other viruses.
