Published: November 2024

Dengue in neonates is an infrequent yet significant cause of neonatal sepsis in endemic areas, often underdiagnosed due to its nonspecific clinical presentation and the lack of specific guidelines for this population. We present a series of three cases of neonatal dengue in patients with fever and signs of late-onset sepsis, who were initially treated with antibiotics without identifying a bacterial agent. Following the diagnosis of dengue through positive IgM, antibiotics were discontinued, and the patients showed favorable clinical outcomes with early hospital discharges. This study highlights the importance of considering dengue as a differential diagnosis in neonates with late-onset sepsis, which could help reduce unnecessary antibiotic use and its adverse consequences. We propose implementing a specific diagnostic algorithm for neonates in endemic regions, including the addition of serological and molecular testing for dengue, to improve management and outcomes in this population.

This study aimed to develop a novel nanotechnological slow-release drug delivery platform based on hyaluronic acid Microsponge (MSP) for the subcutaneous administration of methotrexate (MTX) in the treatment of rheumatoid arthritis (RA). RA is a chronic autoimmune disease characterized by joint inflammation and damage, while MTX is a common disease-modifying antirheumatic drug (DMARD), the conventional use of which is limited by adverse effects and the lack of release control. In this work, MSP were synthesized as freeze-dried powder to increase their stability and allow for a facile reconstitution prior to administration and precise MTX dosing. These MSP exhibited stable, rounded shapes, with a signature open porosity structure, and achieved a high MTX loading efficiency, with a slow release after injection. Our drug release studies demonstrated indeed an initial burst, followed by sustained release over a month. Remarkably, by means of a (collagen induced - CIA) rat model of RA, the MTX-loaded MSP almost doubled the therapeutic efficacy, by significantly reducing arthritic scores compared to controls. The pre-clinical study was replicated twice to confirm this marked improvement in performance and the safety profile of MSP. The results show the potential of MSP mediated therapy to enhance MTX efficacy in RA treatment by enabling sustained slow-release while minimizing side effects. This study therefore suggests that the MSP platform may be considered in clinical practice for improving the MTX delivery in RA therapy.

Machine Learning for Advanced Fraud Detection and Content Moderation
Authors: Babatope Adeoluwa
Published: November 2024

The rapid advancement of digital technologies has led to a corresponding increase in fraudulent activities and harmful content across online platforms, posing significant challenges to both cybersecurity and content integrity. Traditional methods of fraud detection and content moderation, often based on rule-based systems, have proven inadequate in addressing the dynamic and sophisticated nature of these threats. This paper explores the application of machine learning (ML) techniques to enhance the effectiveness of fraud detection and content moderation systems. By leveraging supervised, unsupervised, and deep learning models, ML provides a more adaptive and scalable approach to identifying fraudulent transactions, detecting anomalies, and moderating content on digital platforms. Key methodologies discussed include the use of convolutional neural networks (CNNs) and recurrent neural networks (RNNs) for content analysis and the application of clustering algorithms for anomaly detection in financial transactions. The paper also addresses the challenges of implementing ML-based systems, such as data quality, bias, and the need for real-time processing, and proposes solutions to mitigate these issues. Furthermore, the ethical implications of using ML for these purposes are considered, with a focus on fairness and transparency. The findings demonstrate that ML significantly improves the accuracy and efficiency of fraud detection and content moderation, making it a critical tool in the fight against digital threats. Continued research and innovation in this field are essential to keep pace with evolving threats.
Mathematical Modeling of Salmonella Inactivation During Apple Drying and Preheating in Closed Environments
Authors: Yang Ren , Zhang Shuang , Tang Juming
Published: November 2024

Drying is one of the most effective preservation methods for extending the shelf-life of perishable foods. Microbial safety of the final products has not been a concern until outbreaks reported over the past decade in products contaminated with bacterial pathogens, in particular Salmonella. There is now an urgent need to understand the influence of process conditions on the thermal inactivation of pathogens in various drying operations. This study aimed to develop a predictive model for Salmonella inactivation in diced apples during hot air drying and in high-humidity heating in closed environment. Fresh-cut apple cubes (6 mm) were inoculated with a cocktail of Salmonella enterica strains (Enteritidis PT30, Montevideo 488275, and Agona 447967). The samples were placed in a preheated sample treatment box within a convection oven under three conditions: 1) open air drying, the sample box was open in the oven pre-set at 90°C (Drying-90); 2) closed-box heating, the oven was also set at 90°C (Preheating-90); and 3) closed-box heating, the oven was at 70°C (Pre-heating-70). For open-air drying, hot air at the oven temperature was circulated through the samples, facilitating the heating and drying. In closed box heating, the sample box maintained a high-humidity environment, retaining moisture evaporated from the apple samples and allowing heat conduction through the box walls.
In each test, air temperature, relative humidity (RH), and sample temperatures were monitored, and Salmonella survival was measured at multiple time points. After 10 minutes of heating, the air RH levels in the closed-box configurations were 66% (Preheating-90) and 74% (Preheating-70), much higher than in the Drying-90 condition (30%). Results indicated that in-box heating achieved a 5-log reduction Salmonella after 8.5 min at 90°C, compared to 28.7 min in open air drying at the same temperature. It took 14 min to achieve 5-log reduction at 70°C in in-box heating.
A mathematical model was developed to estimate sample surface RH based on sample temper-ature and ambient absolute humidity, with further adaptation to predict microbial inactivation over time using surface temperature and RH profiles. This model accurately predicted Salmonella inactivation across all treatments (RMSE = 0.92 log CFU/g, R² = 0.86), with thermal death param-eters comparable to literature values from isothermal studies. This study highlights the im-portance of air humidity in enhancing bacterial inactivation during drying and suggests that a preheating step under high-humidity conditions may serve as an effective control measure, en-suring microbial safety before conventional drying. Additionally, this work demonstrates the potential of a nonlinear mathematical model to predict microbial inactivation under complex drying conditions with fluctuating temperature and humidity.

Published: November 2024

Introduction:  Hepatitis B virus infection in fetal and newborn may result from the intrauterine vertical transmission. The purpose of our study is to determine the association between HBsAg expression in the placental and HBsAg serum in pregnant women. Methods: Total 67 placental tissues and serum were obtained from HBV-infected mothers. This study was conducted in various hospitals in Makassar, Indonesia from December 2017 until August 2018. Maternal serum and placental tissues were tested by ELISA and Immunohistochemistry staining. Results: 67 samples from placental tissues and serum were categorized into two different levels of serum titer and staining positivity. Twenty nine samples (43.3%) were categorized in low titer of HBsAg positive serum and 38 samples (56.7%) in high titer of  HBsAg positive serum. From the total of 67 placental samples, 43 (64.2%) samples had positive expression of HBsAg immunohistochemistry staining and 24 (34.8%) samples had negative expressions. Conclusions: There was a significant correlation between the expressions of HBsAg in the placental tissues and serum titers of HBV-infected mothers that is important in predicting the risk of transplacental transmission. The results of this study can be used as guidelines for the prevention and therapeutic approach of mother-to-child HBV infection.

Authors: Bintang Andi Kurnia , Basri Muhammad Iqbal , Lotisna Mimi , Carrey Michael
Published: November 2024

Rabies is a neurological disease with fatal impacts because it has a high mortality rate. Animals, primarily dogs, mediate the spread of rabies. Clinical findings of rabies are divided into two categories: classic rabies (furious type) and paralytic type. Furious rabies has many cardinal features, such as fluctuating consciousness, aerophobia or hydrophobia, inspiratory spasm, and autonomic dysfunction. Ascending paralysis with a lower motor neuron lesion is the initial sign of paralytic rabies. The rabies virus invades and lives in neurons. It is virulent. Besides clinical findings, the diagnostic approach can involve radiology, microbiology, and histopathology. There are not only symptomatic treatments for rabies patients but also vaccines, immunoglobulin, and antivirals to decrease the progressivity of the disease. Vaccination programs and animal control have become essential in reducing rabies cases in Indonesia.

O devido processo legal em investigações administrativas de assédio sexual: a força do mandamento constitucional e a realidade da instrução processual disciplinar
Authors: Pires Daniel , Dezan Sandro Lúcio , Silva Vladia Pompeu
Published: November 2024

This article aims to present the main difficulties in implementing the constitutional principle of due administrative legal process in sexual harassment investigations, especially regarding the selection and obtaining of evidence, as well as the production and evaluation of evidence. First, we analyze the contemporary contours of the principle of due administrative legal process (article 5°, LIV and LV of the Constitution of the Brazilian Federative Republic and articles 20, 21 and 22 - LINDB). Next, we present sexual harassment as an administrative disciplinary infraction. We deal with aspects related to conceptualization, typology and legal provisions. We also analyzed some jurisprudential precedents of the Federal Supreme Court and Superior Court of Justice. Finally, we point out the elements, production and valuation of evidence in the administrative disciplinary procedural investigation of conduct involving the practice of sexual harassment. At this point, we highlight how the nature of the infraction and the victim's condition of vulnerability interfere with the implementation of the guarantees of contradictory and full defense. We conclude that there is a precarious classification system regarding the administrative offense of sexual harassment. This dysfunction ends up having consequences for the development of substantial due process, including with regard to the institute of evidence collection, requiring the evolution of the legislator, in action to combat the practice of sexual harassment in the Public Administration and in terms of accountability.

Published: November 2024

The Berrechid sub-basin of Morocco consists of Late Triassic–Early Jurassic evaporites and red beds that are part of the syn-rift Atlantic series. Although some of the Berrechid sub-basin has been extensively studied, the depositional environment of the Upper Salt-Mudstone Formation has long been debated, with some early studies proposing a marine origin. This study documents the sedimentological, mineralogical, and geochemical characteristics of core materials from two boreholes and mine outcrops covering the entire series of the Upper Salt-Mudstone Formation. Our analysis of the lithology, mineralogy, sedimentary structures, sedimentary textures, and geochemical data suggests deposition in a continental setting. In addition, detailed observations of sedimentary structures and textures indicate additional features of periods of flooding, evapoconcentration, and desiccation. The continental setting in a dry climate is also supported by the occurrence of Classopollis pollen. This study provides new insights of the paleoenvironmental conditions in the Berrechid sub-basin, and significantly advances our understanding of the paleoenvironment and climate of Pangea during the Late Triassic–Early Jurassic period.

Antennas play a fundamental role in modern communication systems by facilitating signal transmission and reception across various frequency bands. Each antenna is designed for specific applications based on its operating frequency range. Whether deployed for Car-to-Car Communication or military operations, antennas serve critical functions, with information security being paramount in military contexts. Vehicular antennas typically operate within the L Band, approximately 1 to 2 GHz, relying on satellites for signal communication. However, traditional transmission through the ionosphere faces limitations, notably the skip zone, where signal reception is hindered, leading to communication failures. To address this limitation, Near Vertical Incident Skywave (NVIS) communication has been developed. NVIS utilizes antennas with very high (> 75°) radiation angles and low HF frequencies to overcome skip zone challenges. Despite existing research efforts, achieving high radiation efficiency remains a challenge, often due to improper antenna angle settings. Additionally, previous studies have overlooked the importance of narrow beam focusing, crucial for long-range communication and direction finding. This paper aims to enhance antenna performance parameters such as efficiency and gain through the adoption of specific techniques. By optimizing antenna design and configuration, we aim to improve performance for ionospheric communication, particularly in military applications involving data and voice transmission.

Alternating current (AС) voltage measurement is one of the most common types of measurements in various fields of science and technology. To evaluate the AC voltage level, special voltmeters are used which allow recording of amplitude, average and/or root mean square (RMS) voltage values. Among these measuring instruments, voltmeters of mean square voltage are especially significant because RMS is a fundamental physical characteristic of an electrical signal and is a true measure of power. The wide distribution of non-sinusoidal signals necessitates the creation of voltmeters for direct measurement of RMS. The main component of such voltmeter is an AC voltage to direct current (DC) voltage measuring converter based on the root-mean-square value level (AC RMS-DC converter). An analysis of existing technical solutions shows that it is advisable to use a thermoelectric converter (TEC) for high-precision measurement of RMS voltage of an arbitrary shape with a spectrum in the frequency band from 20 Hz to 20–50 MHz. Such a AC RMS-DC converter must contain a differential semiconductor TEC and an input broadband voltage amplifier with low nonlinearity of the frequency response. The aim of the paper was to develop a measuring AC RMS-DC converter of arbitrary shape voltage in which special attention is paid to modernization of the TEC and reduction of the AC RMS-DC converter error using corection of the frequency response of the input amplifier and introduction automatic calibration of the output voltage. Features of semiconductor chips and design of TEC in the form of a microcircuit or microassembly, results of converter’s and TEC elements’ parameters measurements are presented. A significant influence of the frequency response of the input amplifier and the offset voltage of the TEC transistors on the AC RMS-DC converter error was noted. Modernization of the input amplifier and introduction of automatic calibration of the output voltage ensured an error in a sinusoidal signal converting of less than 1 % in the range from 20 Hz to 50 MHz.

Currently, it is relevant to create moving objects orientation systems based on the integration of various types of primary information sensors. One way to solve the orientation problem is to use the TRIAD (Tri-Axial Orientation Determination) method which allows determining the matrix of direction cosines between two coordinates. The traditional TRIAD force method is based on the use of two reference vectors – of gravitational and geomagnetic fields, measured by accelerometers and magnetometers, respectively. The disadvantage of this method is – appearance of additional deviations during the accelerated movement of the object and influence of primary information sensors’ random errors. Modified TRIAD method which is based on measurements of three triads of sensors: magnetometers, accelerometers and gyroscopes was proposed in the article. Estimates of acceleration vectors of gravitational and geomagnetic fields were calculated taking into account gyroscope measurements. Then these estimates were combined with the accelerometers’ and magnetometers’ data. The complex gravitational and geomagnetic fields’ accelerations were used to form the direction cosine matrix by the TRIAD method. The suggested modified method can be used to implement free-form moving objects’ orientation systems, since it is 6–8 times more accurate compared to the classic TRIAD method. Attenuation of random sensor errors and disturbances due to object acceleration can be adjusted by use of weigh factors.

Thermally expanded graphite belongs to a new class of graphite materials with unique physical, chemical and mechanical properties. Acoustic wave velocity is one of the most important characteristics for study of porous materials including thin porous sheets of thermally expanded graphite. In this paper peculiarities of symmetric mode S0 Lamb wave propagation and SH-wave with horizontal polarization in sheets of thermally expanded graphite are experimentally investigated. To determine their velocities a differential measurement scheme on the base of a low-frequency acoustic flaw detector DIO1000 LF and specialized piezoelectric transducers with dry point contact was used. Additionally the longitudinal wave velocity in direction of sheet thickness was determined using piezoelectric transducers based on polyvinylidene fluoride. Indicatrices of normal wave velocities in the rolling plane were plotted and it was shown that the maximum acoustic anisotropy is characteristic for the S0-mode. The velocity minimum corresponds to the longitudinal direction of the rolling plane in which the maximum elongation of gas pores was observed. Influence of thickness and density of thermally expanded graphite sheets on the velocities of normal waves was investigated and presence of the thickness range where the minimum velocity values were observed due to the maximum inhomogeneity of layers formed in the rolling process. Method for determination of dynamic elastic moduli of porous thermally expanded graphite sheets using experimentally measured velocities of normal waves was proposed. It was shown that in the longitudinal direction of the rolling plane the Poisson's ratio took negative values which allow to attribute the specified material to auxetics ones.

Published: November 2024

Semiconductor materials based on ZnO and RE3+MnO3 oxides are considered as potential candidates for spintronics. This article presents the methodology and results of studying the effect of magnetic circular dichroism for Zn1-xCoxO, Zn1-x-yCoxAlyO and RE1-x 3+Ax 2+MnO3 film structures in the visible radiation range. It has been shown that the magnetic circular dichroism behavior of the manganite films reflects not only the magnetic, but also the charge component of the material. This indicates the possibility of studying the magnetic and transport characteristics of the films using the magnetic circular dichroism spectroscopy. Since the magnetic circular dichroism effect also directly probes the ground and excited electronic states of the film, it has been obtained data that update calculated parameters for describing the manganites band structure. In the case of the Zn1-xCoxO and Zn1-x-yCoxAlyO films, the magnetic circular dichroism spectroscopy acts as a tool for detecting Co nanoparticles in the solid solution matrix of ZnO:Co and ZnO:(Co+Al).

Authors: Al Busafi Maher
Published: November 2024

Petroleum Development Oman (PDO) has been at the forefront of deploying fiber optic technology as a surveillance tool in multiple Enhanced Oil Recovery (EOR) techniques across the Sultanate of Oman. This initiative aims to accelerate and enhance recovery from mature fields while ensuring the highest levels of well integrity. However, the increase in production activities has coincided with heightened concerns over well integrity, particularly relating to operational challenges and the cost-effectiveness of maintaining optimal uptime. Additional concerns include Health, Safety, Security, and Environment (HSSE) risks that cannot be overlooked, especially in high-risk environments characterized by H2S, HPHT (High Pressure High Temperature) settings, and remote locations. Moreover, significant production deferments resulting from integrity issues can severely impact high-producing wells.

This paper explores the application of fiber optic technology within PDO's operations and examines its far-reaching implications for monitoring well integrity, boosting operational efficiency, and enhancing safety management procedures. The findings highlight the transformative potential of fiber optics in revolutionizing how oil and gas operations manage well integrity issues, ultimately contributing to more sustainable production practices.

The Real-Time Operations Center (RTOC) plays a crucial role in overseeing drilling operations, focusing on maintaining operational safety and efficiency. Our main goal is to improve the prompt identification and handling of various drilling anomalies, categorized into hookload (overpull, slack off, restrictions), pressure anomalies, and torque issues (over torque, pipe stalling, stick-and-slip), to prevent costly and dangerous situations.

We've developed a hybrid, two-step anomaly detection model to boost the effectiveness of RTOCs. This model includes the Anomaly Identification Model (AIM) and the Gate Filtering Model (GFM). The AIM uses traditional machine learning to recognize known anomaly patterns and deep learning to spot complex, subtle discrepancies using real-time surface data such as bit depth, hole depth, hook load, block position, stand pressure, flow rate, RPM, and torque. The GFM combines algorithmic approaches and machine learning techniques to filter out most false positives by focusing on areas with a higher likelihood of anomalies.

Our model is now in use on live drilling wells, processing 100+ wells daily. In practice, it has significantly improved the detection and handling of anomalies. There have been several instances where the model detections were followed by actions that prevented incidents like stuck pipes. The model has the capacity to only raise anomalies when there is a real risk, ensuring that alerts are meaningful and actionable. These findings highlight the model's ability to detect anomalies and the essential need for timely action following these detections.

This model introduces a new approach by integrating various machine learning methods to greatly reduce the need for manual data review. By enabling RTOC staff to focus more on strategic decisions rather than routine data monitoring, the model not only enhances safety but also improves operational efficiency. The Gate Filtering Model (GFM) ensures alerts are meaningful and not merely noise, allowing the system to alert but not to annoy. Our upcoming paper will elaborate on this methodology and provide an extensive performance analysis of the model.
