Published: February 2025

Background: Oesophageal high-resolution manometry (HRM) is commonly used in the evaluation of patients presenting with upper gastrointestinal tract symptoms where primary oesophageal motility disorders are suspected. At our hospital, one doctor can perform and interpret HRM, with the hospital serving a population of approximately 3 million people. There is a paucity of data on HRM findings in South Africa.Methods: This study included data from patients that underwent HRM between January 2018 and January 2023, using the hospitals electronic note-keeping system to access records. High-resolution manometry was performed for all patients using a water state catheter with 24 pressure channels. The Chicago classification version 3 was used for reporting.Results: A total of 210 patients were included in this study. The average age of patients included was 50 years (standard deviation [s.d.] ± 15.2) old with a female predominance (n = 149, 71.0%). Indications included gastroesophageal reflux disease (GORD) (65.7%), refractory heartburn (62.4%), dysphagia (37.6%), non-cardiac chest pain (16.7%), pre-procedurally (5.7%) and post-procedurally (14.8%). Many primary oesophageal motility disorders were observed, including ineffective oesophageal motility (20%), achalasia (11.4%), absent contractility (4.3%), oesophagogastric junction outflow obstruction (1.9%) and jackhammer oesophagus (1%). Normal findings accounted for 61%. The most common type of achalasia was type 1 (n = 16, 66%).Conclusion: This study, being the first of its kind in South Africa, highlights the role of HRM in the diagnosis of primary oesophageal motility disorders with ineffective oesophageal motility being the most common pathology and GORD being the most common indication for HRM. Achalasia type 1 was the common type diagnosed.Contribution: HRM, despite its scarce availability, remains an important diagnostic tool in evaluating gastrointestinal pathologies.
On GIT stability of linear systems of hypersurfaces in projective spaces
Authors: Hattori Masafumi , Zanardini Aline
Published: February 2025

In this paper, we consider the problem of classifying linear systems of hypersurfaces (of a fixed degree) in projective space up to projective equivalence. Our main result consists of a complete criterion for (semi)stability in the sense of geometric invariant theory (GIT). As an application, we inspect a few relevant geometric examples recovering, for instance, Miranda’s characterization of GIT stability of pencils of plane cubics. Furthermore, we completely describe GIT stability of Halphen pencils of any index.
Fine‐tuning XLNet for Amazon review sentiment analysis: A comparative evaluation of transformer models
Authors: Shetty Amrithkala M. , D. H. Manjaiah , Aljunid Mohammed Fadhel
Published: February 2025

Transfer learning in large language models adapts pretrained models to new tasks by leveraging their existing linguistic knowledge for domain‐specific applications. A fine‐tuned XLNet, base‐cased model is proposed for classifying Amazon product reviews. Two datasets are used to evaluate the approach: Amazon earphone and Amazon personal computer reviews. Model performance is benchmarked against transformer models including ELECTRA, BERT, RoBERTa, ALBERT, and DistilBERT. In addition, hybrid models such as CNN‐LSTM and CNN‐BiLSTM are considered in conjunction with single models such as CNN, BiGRU, and BiLSTM. The XLNet model achieved accuracies of 95.2% for Amazon earphone reviews and 95% for Amazon personal computer reviews. The accuracy of ELECTRA is slightly lower than that of XLNet. The exact match ratio values for XLNet on the AE and AP datasets are 0.95 and 0.94, respectively. The proposed model achieved exceptional accuracy and F1 scores, outperforming all other models. The XLNet model was fine‐tuned with different learning rates, optimizers (such as Nadam and Adam), and batch sizes (4, 8, and 16). This analysis underscores the effectiveness of the XLNet approach for sentiment analysis tasks.

Published: February 2025

BACKGROUND

Hepatocellular carcinoma (HCC) is a malignant disease with high incidence and mortality worldwide. This study focuses on the TP53 target protein to investigate the potential therapeutic effect of tetrahydrocurcumin (THC) on HCC and its mechanism of action. The research hypothesis is that THC can inhibit the proliferation, migration, and invasion of HCC cells, and promote their apoptosis by regulating the TP53 target protein.

AIM

To explore the mechanism by which THC inhibits HCC cell proliferation via the TP53 signaling pathway.

METHODS

Potential targets of THC and HCC were identified from multiple databases. The core targets were subjected to analyses using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes databases, and visualization processing, using the online platform Metascape to identify the key molecules and signaling pathways involved in the action of THC against HCC. The molecular mechanisms of action of THC against TP53 in the inhibition of HCC cells were verified using cell counting kit-8, Transwell, apoptosis, and western blotting assays.

RESULTS

Molecular docking results showed that THC had a high score for the TP53 target protein. In vitro experiments indicated that THC effectively inhibited the proliferation and migration of HCC cells, and affected the expression levels of TP53 , MDM2 , cyclin B , Bax , Bcl-2 , caspase-9 , and caspase-3 .

CONCLUSION

THC induces the apoptosis of HCC cells through the TP53 signaling pathway, thereby inhibiting their proliferation and migration.
Assessing the competitive dynamics of AI partnerships
Authors: Carugati Christophe , Kar Nicole
Published: February 2025

Artificial intelligence (AI) partnerships have become a prevalent strategy in AI markets, enabling developers to access critical resources for developing and deploying AI models. As concerns over market concentration and potential anti-competitive practices by incumbent firms grow, competition authorities worldwide are intensifying their scrutiny of these partnerships, using a range of enforcement and regulatory tools. However, reviewing these partnerships presents new and complex competition challenges.

This paper first categorizes AI partnerships into five types based on their rationale, namely, expertise, data, compute, distribution and investment. It then explores key competition concerns identified through market studies and investigations, analysing them through the frameworks of merger laws, antitrust laws and relevant regulations. The paper concludes with policy recommendations, suggesting competition authorities ensure predictability in the application of merger control rules to provide legal certainty, make competition principles more actionable and develop pro-competitive and innovation-friendly regulations.

Published: February 2025

SMP Muhammadiyah Tebing Tinggi merupakan salah satu lembaga pendidikan umum dan agama yang berperan penting dalam pembentukkan karakter serta kecerdasan dan kepribadian anak-anak. Absensi kehadiran merupakan bagian peranan penting dalam setiap instansi pendidikan. Dimana absensi merupakan salah satu penunjang utama yang dapat mendukung dan memotivasi setiap kegiatan yang dilakukan di dalamnya. Seperti halnya absensi di SMP Muhammadiyah Tebing Tinggi yang masih menggunakan cara manual (tanda tangan), cara ini sangatlah rawan bagi suatu lembaga pendidikan karena tingkat kedisiplinan yang tidak dapat di kontrol dan dapat disalah gunakan oleh orang yang tidak bertanggung jawab, kerugian lain yang mungkin muncul pada sistem absensi manual adalah rekapitulasi data yang masih memakan banyak waktu dan tenaga, oleh karena itu dirasakan perlu penggunaan komputer sebagai alat bantu untuk pengolahan data absen dengan menggunakan aplikasi yang dirancang sedemikian rupa sesuai dengan kebutuhan sekolah yang bersangkutan.

Published: February 2025

A house is a primary need that everyone must have, yet not everyone can afford to purchase it outright. Therefore, a bank is needed as a financial institution to provide financial assistance through credit disbursement. Bank Syariah Indonesia (BSI) offers several Home Ownership Credit (HOC) programs with the Murabahah sale and purchase contract. The current analysis of eligibility determination for granting KPR credit at Bank BSI does not yet utilize an appropriate method for decision-making. This study aims to design a Decision Support System (DSS) using the Additive Ratio Assessment (ARAS) method to assist Bank BSI in analyzing KPR customer data quickly, accurately, and precisely. The ARAS method focuses on comparison with an ideal solution, ensuring that the best alternative approaches optimal conditions based on the specified criteria. The results of this study can help Bank BSI determine the eligibility of KPR credit disbursement more effectively, and the system can rank customer data as eligible or not eligible based on predefined value thresholds.

Impact of Salinity Level on Measured Hardness of Different Paint and Varnish Coatings
Authors: MIREK Przemysław , CZERNIAK Jacek
Published: February 2025

The main problem addressed in this work is the possible impact that the salinity of different environments may have on commercially used paint and varnish coatings. The main motive in conducted studies is to determine the impact of different environments to paints and varnishes hardness. Current literature lacks detailed research on how environmental factors, like exposure to naturally present salt particles can affect their features such as hardness. Research in this area could be helpful as a way to assess the level of possible damage it may be posing to these protective layers. In this research, the damping pendulum method has been used to identify changes to hardness of different coatings. All methods used in studies are based on ISO 1522:2008r. The types used were selected to represent a variety of different uses eg. outdoor house renovation, car coatings, indoor furniture paints, nautical boat coatings, high-temperature-resistant paint, anti-corrosion coatings, as well as nail lacquer. Different chemical composition was considered as a main factor that could have influenced the results. The most resistant to salinity changes, in terms of hardness, were coatings characterized by high solvent content – heat resistant and automotive paint. This proves that exposure to a high salinity environment can have a huge impact on commonly used coatings and resistance to it should be taken into account. Conducted studies shows that different environments have impacts to paints and varnishes coatings.

Retrieving Vertical Profiles of Cloud Droplet Effective Radius using Multispectral Measurements from MODIS: Examples and Limitations
Authors: Buggee Andrew John , Pilewskie Peter Andrew
Published: February 2025

Abstract. With the coming launch of the Climate Absolute Radiance and Refractivity Earth Observatory (CLARREO) Pathfinder (CPF) comes an opportunity to develop a new cloud retrieval from spectral reflectance measurements. With continuous coverage across the shortwave spectrum and a factor of 5 to 10 lower radiometric uncertainty than the Moderate Resolution Imaging Spectroradiometer (MODIS), CPF facilitates the retrieval of a vertical profile of droplet size, providing insight into the internal structure of a cloud. Measurements from MODIS coincident with in situ observations provide the foundation for developing a constrained optimal estimation technique, ensuring a solution consistent with forward model assumptions. The limited unique information in the MODIS bands used in this analysis led to a non-unique solution, with many droplet profiles leading to convergence. Droplet size at cloud bottom is difficult to constrain because visible and near-infrared reflectances have an average penetration depth near cloud top. The region of convergence within the solution space decreased along the cloud bottom radius dimension by 2 μm when increasing the number of wavelengths used in the retrieval from seven to 35, and by 5 μm when reducing the measurement uncertainty from 2 % to 0.3 %. The enhanced accuracy and, to a lesser degree, the enhanced spectral sampling provided by CPF measurements are essential to extracting vertically resolved droplet size information from moderately thick, warm clouds.

Abstract. Here we introduce the first version of the Global Interpolated RAinfall Estimation (GIRAFE v1), the first dedicated global climate data record for precipitation by the Satellite Application Facility on Climate Monitoring (CM SAF) by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT). GIRAFE is based on precipitation rate estimates obtained from observations by a variety of passive microwave radiometers onboard low-Earth orbit satellites and related retrieval algorithms and frequent and highly resolved infrared observations by geostationary satellites covering all longitudes (Geo-Ring). GIRAFE v1 is available globally at 1-degree resolution as daily accumulations and monthly means for the years 2002–2022, with an implementation of continuous production planned for 2025 onwards. The daily product is accompanied by a dedicated sampling uncertainty estimate based on decorrelation scales in space and time in infrared-based instantaneous precipitation fields. The methods for the generation of GIRAFE v1 are described in detail, followed by results of dedicated quality assessment and intercomparison activities. GIRAFE v1 reproduces reference datasets with a performance similar to established precipitation products, especially as those that are – like GIRAFE v1 – not adjusted to ground-based observations. Likewise, GIRAFE v1 proves to be suitable for the analysis of regional precipitation extremes, e.g. in their relation to sea surface temperatures. The main objective in the production of GIRAFE v1 is climate applications, for which we find the dataset highly suitable according to the dedicated stability and homogeneity analysis. The GIRAFE v1 data record is hosted by CM SAF and is freely available at https://doi.org/10.5676/EUM_SAF_CM/GIRAFE/V001 (Niedorf et al., 2024).
Application of wave–current coupled sediment transport models with variable grain properties for coastal morphodynamics: a case study of the Changhua River, Hainan
Authors: Wu Yuxi , Zhao Enjin , Li Xiwen , Zhang Shiyou
Published: February 2025

Abstract. This study introduces an integrated sand transport model that considers wave and current actions alongside variable grain properties to explore sediment dynamics in river deltas. The research delves into a case study of a river delta region, examining sediment transport over a substantial stretch of the river's lower course. The study incorporates topographic data, sediment sampling, and remote sensing to validate the model against observed suspended sediment concentrations at a key monitoring station. The results reveal substantial sediment deposition in both the estuary and lower reaches of the river, influenced by hydrodynamic conditions and geological settings. Deposition patterns in the estuary are primarily driven by coastal currents and wave action, while river channel deposition is linked to river constriction and flow velocity variations. The study demonstrates that the residual current in the region consistently flows towards a nearby bay, suggesting that sediment in the lower reaches of the river will be directed by this residual flow. The study underscores the pivotal roles of current and wave action in sediment transport within a multi-branched estuary characterized by low sediment concentrations, which can inform coastal management and environmental planning.

groups received aqueous extract of E. guineensis at 100, 200
and 400 mg/kg doses per gavage during 54 days (males)
and 10 days (females). Subsequently, males were mated
in rapport 1:2 (females untreated and treated) during 10
days, while receiving extract. After mating, sexual behavioral
parameters (mount latency and frequency, intromission
latency and frequency, ejaculation latency and frequency,
post ejaculation interval, Average interval of copulation)
were recorded in males using ovariectomized female’s rats
(10). In females the percentages of fertility, fecundity and
prolificacy were calculated. Consecutively, treated rats were
serially sacrificed; Sperm count and histologic analysis of
androgen and estrogen dependent organs and pituitary gland
were evaluated. Organs section of treated groups presented
normal architecture, and sexual behavioral parameters
did not show any significant difference when compared to
control group. Sperm count significantly increased at 200 mg/
kg dose. The percentage of fertility was 100% in all groups,
but the percentages of fecundity and prolificacy significantly
decreased at the dose of 400 mg/ kg. Aqueous extract of E.
guineensis roots did not affect sexual behabior, improved
fertility at traditional use dose, but could negatively affect
spermatozoids’ structure and fetus development at high doses.
AI-Powered Recruitment: Transforming Talent Acquisition in the Digital Age
Authors: Kumar C
Published: February 2025

Artificial intelligence (AI) has brought about change in the manner of traditional recruitment processes. It has improved the efficiency, accuracy, and experiences of candidates during the process significantly. The organizations are also fast adopting such AI-driven solutions in the form of resume-screening algorithms, chatbots, predictive analytics, and video interviews for assessments by streamlining the decision-making. However, concerns around the fairness of AI and reduction of bias in hiring successes are highly controversial. This study investigates the statistical effect of AI adoption on the effectiveness of recruitment using a quantitative research method. AI adoption acts as an independent variable, while recruitment efficiency, reduction of bias, and candidate experience are dependent variables. A total of 250 responses was collected from HR professionals across multinational corporations and startups with the help of structured questionnaires. Multiple regression analysis using SPSS was conducted to determine the relationships between AI adoption and the identified recruitment outcomes. The results show that AI adoption significantly influences efficiency in recruitment (β = 0.58, p < 0.001) and candidate experience (β = 0.61, p < 0.001); in other words, AI-driven tools speed up the process of hiring and enhance candidate engagement. Nevertheless, it was also concluded that AI has a positive, albeit weak, impact regarding bias reduction: β = 0.32, p = 0.041. This indicates that AI alone cannot completely remove the inherent biases of recruitment; hence, there is an ongoing need for human supervision and improvement of the models of AI. These results present both the opportunities and challenges associated with AI-driven recruitment. While AI saves a lot of time in the hiring process and improves the candidate experience, issues of fairness, algorithmic bias, and ethical concerns still prevail. Best practices for organizations include regular auditing of AI-driven tools, high-quality data input, and integration of human decision-making with AI solutions. Ethical considerations of data privacy, transparency, and responsible use of AI will help in gaining trust in the technology by both candidates and HR practitioners. This is an empirical study adding to the growing body of literature on AI in HR, as there has been little to no statistical relationship between AI adoption and key recruitment metrics. Hence, future research should focus on longitudinal studies that will examine the long-term impact of AI on recruitment and assess additional moderating variables such as industry type, company size, and AI training methodologies. The study provides clear evidence that a balanced approach is required, in which AI could complement but not replace human judgment in recruitment decisions.

Investigating how digital branding tactics impact consumer behavior is the goal of this study, which focuses on the FMCG (fast-moving consumer goods) sector in India. Considering social media's growing effect on purchasing choices, the research aims to examine the connections between brand memory, digital marketing, social media engagement, and consumer interaction with online content.  The research used a survey to examine 500 customers' knowledge, engagement, and responses to several digital branding tactics. The purpose of the data collection was to evaluate the ways in which various digital strategies affect customer behaviour.  The results indicate that a sizable portion of customers follow FMCG businesses on social media. Higher degrees of engagement with digital material have been linked to increased brand loyalty and a higher propensity to buy. Important digital branding techniques that were shown to be successful in influencing customer decisions were influencer endorsements, e-commerce agreements, tailored suggestions, and social media ads.

Un ecosistema de innovación se define como una red interconectada de actores, incluyendo organizaciones, clientes, proveedores y reguladores, que trabajan juntos para crear valor y enfrentar tanto colaboración como competencia. En el ámbito local, estos ecosistemas pueden impulsar el desarrollo económico y fomentar una cultura emprendedora en sectores productivos específicos, como el sector lácteo de Honduras. Este sector, que contribuye significativamente a la economía nacional y genera numerosos empleos, enfrenta desafíos en áreas como producción, calidad, inocuidad e innovación, principalmente debido a prácticas tradicionales y tecnología limitada. Este ensayo argumenta que la implementación de ecosistemas locales de innovación, donde las universidades desempeñen un papel protagónico, puede transformar el sector lácteo a través de investigación, desarrollo e innovación. La colaboración público-privada y el papel de las universidades son fundamentales para el éxito de estos ecosistemas, ya que generan conocimiento, forman talento especializado y promueven la transferencia tecnológica. Además, las universidades actúan como centros de investigación y desarrollo en alianza con empresas y gobiernos, fomentando el crecimiento económico y la competitividad. La cooperación entre los actores facilita el intercambio de conocimiento y la adopción de prácticas avanzadas, mientras que la integración de estrategias científicas, tecnológicas e innovadoras, junto con programas de formación continua, optimizan los procesos productivos y mejoran la calidad y seguridad de los productos lácteos. Para superar los retos del sector lácteo hondureño, es esencial establecer programas de formación permanente, desarrollar plataformas de innovación abierta y diseñar sistemas efectivos de monitoreo y evaluación de proyectos de I+D+i. Experiencias exitosas respaldan estas iniciativas, las cuales permiten una mejor adaptación a las demandas del mercado y contribuyen a mejorar la calidad de vida de los productores del sector.
