Authors: CAO Jiajun , ZENG Xin , LYU Zhen , CAI Weiwei , LIU Hong , LIU Yingzheng
Published: December 2024

A benchmark evaluation of the event-based imaging velocimetry (EBIV) on its acquisition capability and measurement uncertainty is performed. Toward this end, a digital micro-mirror device interfaced with a pulsed laser light source is employed to generate the illuminated particle image under various predefined particle diameters and concentrations, serving as the ground truth base. For ease of comparison, a frame-based camera is used to provide the reference particle images. The measurement results indicate that the maximum frame-recovered acquisition frequency decreases as particle image diameter or concentration increases, converging to a minimum level of 2,400 Hz for the EVK4 event-based camera. Despite this lower limit of frequency, adding large-diameter and high-concentration particles may induce event loss and then lead to incorrect velocity measurements. This deficiency can be avoided by maintaining a margin of around 5% between the maximum acquisition frequency and its lower limit, which corresponds to the frequency above 2,500 Hz in this study. Furthermore, at the acquisition frequency over 2,500 Hz, a diameter of 2.20 px exhibits the lowest mean velocity uncertainty; whereas, at the acquisition frequency below 2,500 Hz, a diameter of 2.20 px and 3.06 px can both achieve the lowest uncertainty level. A linear model is also proposed to estimate the maximum acquisition frequency for practice purpose. This work determines the relationship among acquisition frequency, particle size and concentration for the EBIV system. Finally, a two-dimensional EBIV experiment of a water jet is successfully conducted at 4 kHz for demonstration.

Peripartum cardiomyopathy: current state of the problem
Authors: Lutai Ya.M.
Published: December 2024

Peripartum cardiomyopathy (PCMP) is cardiomyo-pathy with left ventricular systolic dysfunction that develops in late pregnancy or in the first months of postpartum period. Clinical manifestations can vary from mild or moderate to severe symptoms of heart failure with significant functional limitation and high mortality. PCMP has a rather heterogeneous and incompletely studied pathophysiology, which includes hormonal, vascular, metabolic, and immunological pathways, whose implementation becomes possible on the background of genetic predisposition. Treatment is based on heart failure therapy, taking into account the risks associated with pregnancy and lactation. Bromocriptine is being considered as a specific therapy; however, the level of evidence for such treatment is insufficient. The article covers basic information about the pathophysiology, diagnosis, prognosis, prevention and treatment of PCMP at the current stage. For writing this review, the literature search was conducted using the MEDLINE, Scopus, and Web of Science databases.

The world trend of military surgery of last decades is an improvement of treatment outcomes in combat trauma, the reduction of both early and late mortality, which is associated with the training of combatants in providing first aid, self-help, improving medical logistics, implementing the principles of damage control surgery and early resuscitation, staging of assistance. However, in the structure of mortality, especially late, the leading positions, as before, belong to acute lung damage, acute respiratory distress syndrome, multiple organ failure whose pathogenesis is considered in this review. The conceptual tool of this study goes beyond the usual surgical one. However, just as combat trauma requires a multisystem approach, so the solution to the problem of multiple organ failure can be found only with the interaction of various disciplines, and therefore only this level of understanding of this problem opens the prospect of further development.

Background. The global epidemic of strong synthetic opioids and “new” psychoactive substances has increased the number of overdoses that cause prolonged coma with subsequent persistent vegetative state or apallic syndrome. The purpose was to investigate the clinical manifestations, functional and pathohistological changes of the brain in apallic syndrome due to severe drug poisoning (overdose). Materials and methods. A retrospective analysis of the medical data of six people aged 21–38 years with drug poisoning involving illegal methadone, psychostimulants, barbiturates and alcohol was carried out. Results. Among the patients of the toxicology department of the Kyiv City Clinical Emergency Hospital in 2008–2020, an increase in the number of cases of apallic syndrome was noted from 0.025 to 0.14 ‰, which correlates with mass poisonings with illegal methadone. A key role in the diagnosis of apallic syndrome of toxic origin belongs to the neurological and behavioural examination of the patient, which should be carried out by experienced neurologists specialising in counselling people with poisoning. Functional magnetic resonance imaging and positron emission tomography are the modern standard for diagnosing vegetative states; however, these methods are still difficult to access in Ukraine. The visualization zones of the pathological process in the brain in case of toxic damage are mainly basal ganglia and/or thalamus and dentate nucleus, cortical zone of grey matter, periventricular zone of white matter, corticospinal tract and corpus callosum; asymmetric white matter damage as a sign of demyelination; parietal-occipital subcortical vasogenic edema and lesions of the central pons are characteristic. Forensic and histological studies of the cerebral cortex revealed diffuse loss of neurons, neuronophagia, satellitosis, deformed pyramidal neurons with apical dendrites and manifestations of homogenising necrosis, angiomatosis microfoci and neuropil vacuolation, mineralization of the tissue and a moderate glial reaction around the petrifications. Conclusions. For the health care system of Ukraine, it remains relevant to improve the existing definitions and diagnostic criteria of the apallic syndrome, which attracts the attention of doctors in connection with an increase in cases of life extension of patients after waking up from a long coma.
The influence of intermittent venovenous hemodiafiltration on the course of acute kidney injury in multiple trauma victims
Authors: Dubyna V.M. , Kravets O.V.
Published: December 2024

Background. Acute kidney injury (AKI) is a common complication of polytrauma that requires renal replacement therapy (RRT) in 10 to 28 % of cases. RRT methods can be divided into discrete, or intermittent, and continuous. There are currently no clear recommendations regarding the choice of the RRT method. The purpose was to study the effect of intermittent venovenous hemodiafiltration (HDF) on indicators of renal function, hemodynamics, homeostasis and inflammation in multiple trauma victims with rhabdomyolysis and AKI. Materials and methods. Fifty victims with multiple trauma complicated by rhabdomyolysis and AKI were examined. We investigated the levels of total creatine kinase and myoglobin, indicators of kidney function, frequency of vasopressor support, indicators of general blood analysis, liver complex, coagulogram, acid-base and gas composition of blood. The study was conducted upon admission, before the start and after the end of each HDF session and on the last day of treatment. Results. Multiple trauma with massive rhabdomyolysis led to AKI, manifested by oliguria and hyperazotemia (and from the 3rd day, by hyperkalemia), as well as cardiovascular failure, anemia, liver dysfunction, and inflammatory response. AKI progression to renal failure despite conservative therapy led to the beginning of HDF on 3.6 ± 0.8 days of hospital stay. HDF allowed to effectively reduce indicators of the renal complex and normalize the potassium level, and at the same time did not have a negative effect on hemostasis or other indicators of homeostasis. 72.9 % of victims needed two HDF sessions, 47.9 % — three, 31.3 % — four or more. The most pronounced reduction of hyperazotemia was observed after the second session. Among the survivors, restoration of adequate diuresis by the day 14 was observed in 39.3 % of cases. The mortality rate was 34.0 %. Laboratory markers of renal function were not significantly different between survivors and deceased; the difference was in markers of liver function, coagulogram and acid-base balance, as well as the need for vasopressor support. That is, the mortality was due to the progression not so much of kidney failure, but of the failure of other organs and systems. It should also be noted that the injury severity score among survivors was 23.5 ± 4.0 points, and among non-survivors — 40.5 ± 6.8 points (p < 0.001). Conclusions. Multiple trauma with massive rhabdomyolysis leads to the development of multiple organ failure. Intermittent HDF allows to quickly and effectively reduce azotemia and normalize potassium levels without adversely affecting coagulation or other indicators of homeostasis. Most multiple trauma victims need 2 or more sessions of HDF. Mortality remains high and primarily depends on the severity of anatomical injuries and the addition of other organs and systems failure.

Background. Regional anesthesia has become widely used in routine anesthesiology practice, it is considered a safer method of anesthesia in older patients and those with concomitant pathology. Nevertheless, both general and regional anesthesia have side effects on the cardiovascular system. The cardiotoxic effect of anesthesia in one way or another is present with any variant of anesthesia. One of the most transparent signs is rhythm alterations on the ECG. These changes can occur not only intraoperatively, but also in the early postoperative period, have an asymptomatic clinical course. But the presence of these signs can have a negative impact on the patient’s prognosis. That is why we performed daily Holter monitoring for patients undergoing trauma surgery. The purpose of the study was to compare regional and general anesthesia as a risk factor for perioperative rhythm disturbances. Materials and methods. It was a 2-group observational study that included 120 trauma patients undergoing surgery using general (group GA) or regional anesthesia (group RA). Postoperative Holter monitoring lasted 24 hours. Further analysis of the recording included the assessment of the presence of ischemic changes or extrasystoles. Results. The incidence of ST-depression episodes within 24 perioperative hours was 10 % in the GA group compared to 3 % in the RA group. In the GA group, the percentage of extrasystole was significantly higher compared to the RA group: 1.5 ± 2.1 % versus 0.7 ± 1.3 % (p = 0.0145). An increase in Qtd was significantly higher in the GA group 15 minutes after the start of anesthesia (51.31 ± 23.09) compared to the RA group (40.70 ± 19.97; p = 0.008). At the same time, QT dispersion was statistically significantly higher in the RA group 1 hour after the start of anesthesia compared to the GA group — 38.22 ± 12.30 versus 50.1 ± 19.5 (p = 0.04). The QT interval was significantly longer in the GA group 15 minutes after the start of anesthesia: 440.00 ± 33.09 versus 400.70 ± 23.18 in the RA group (p = 0.04). One hour after the start of anesthesia, QTt was longer in the RA group: 390.22 ± 23.60 versus 410.1 ± 30.1 in the GA group (p = 0.05). Conclusions. Regional anesthesia has less hemodynamic effects and is the method of choice in patients with cardiovascular comorbidity. However, given the risk of cardiotoxicity due to the resorptive effect of the local anesthetic, in older patients and with existing risk factors, it is crucial to account for the arrhythmogenic effects of local anesthetics and adjust the dosage accordingly.

How to safely perform laparoscopic cholecystectomy: anatomical landmarks
Authors: Chooklin S.M. , Chuklin S.S.
Published: December 2024

Bile duct injury rates in laparoscopic cholecystectomy remain higher than during open cholecystectomy. Intraoperative injuries are mostly the result of a misinterpretation of anatomical structures due to severe inflammation or topographical variations. Standard laparoscopic cholecystectomy requires proper dissection of Calot’s triangle to achieve the critical view of safety (CVS). The CVS is the end product of dissection, and bile duct injuries occur before the conclusion of that process. The CVS cannot always be achieved in cases of severe cholecystitis because of technical difficulties. A complete strategy of safety should therefore include early recognition of difficulties and identification of cholecystectomies, when the CVS cannot be achieved, in order to utilize new intraoperative technologies to clarify the anatomy. Fixed anatomical landmarks can help in proper orientation to ascertain the surgical anatomy correctly during surgery. Encompassed within the review are insights into identifying critical landmarks for assessing the positioning of vital structures in compromised anatomical conditions.

Published: December 2024

With the revolutionary change in emerging technologies, the usage of drones or unmanned aerial vehicles (UAV) has exponentially increased in different sectors like Industry, healthcare, military, agriculture, real estate, manufacturing, logistics, energy and many more utilities. This rapid growth creates a concern for the secure communication between the internal communication modules and the ground based computer system used for controlling the UAV. Intruder can hack into the device and attack the internal communication device with the injection of the malicious code which can lead to the malfunction of the aircraft. Security issues related to the communication between the internal modules of the drone and the ground based computer system is of major concern and is crucial. UAVs have to operate in constrained networks with limited bandwidth. In such a constrained environment MQTT protocol can be an excellent protocol. No cryptographic techniques are used to retain the simplicity and the light weight of the MQTT protocol. This contributes for the large scope for emerging with new solutions in the protection issues of MQTT communications. This paper mainly focuses on Armstrong number encryption standard algorithm for providing a computationally simple yet a secure and strong algorithm for UAVs encryption and decryption process on the communication links using MQTT protocol.

To effectively manage and interpret sensor data, we employ Gaussian Process Regression (GPR) to model the underlying uncertainties in fluid-structure interactions, allowing for more precise predictions in complex and varying environments. The probabilistic nature of GPR enables quadruped robots to handle noisy data and provide robust, uncertainty-aware decision-making strategies.

We train and evaluate the model using real-time sensor data, which includes ambient environmental factors and the robot's internal states. A key focus of our study is the robot's adaptive response to different hydrodynamic conditions, such as varying speeds and fluid dynamics. The results demonstrate that the GPR-based model efficiently learns and adapts to these dynamic conditions, leading to accurate force prediction and enhanced autonomous performance in a range of real-world scenarios.

Published: December 2024

The article investigates the potential of serverless architectures for efficiently processing large-scale metadata generated by Internet of Things (IoT) sensors. As IoT systems grow increasingly complex, the challenges associated with processing vast amounts of data in distributed environments become more pronounced. Key issues include ensuring data accuracy, maintaining scalability, and reducing the operational costs of data processing infrastructure. The paper proposes serverless computing as a highly adaptable solution to these challenges, focusing on its capacity for real-time processing, dynamic scaling, and seamless integration with modern cloud platforms. The research highlights the importance of dynamic calibration of IoT sensors to ensure the accuracy and reliability of collected data. Dynamic calibration addresses challenges such as environmental changes and sensor degradation, leveraging serverless systems to automate recalibration based on real-time data analysis. The authors propose an architecture based on Amazon Web Services (AWS) to demonstrate the practical application of serverless principles. This architecture incorporates AWS Lambda for computational tasks, SQS for workload distribution, and S3 for scalable data storage.

The article emphasises the advantages of serverless systems, including cost-efficiency, resource optimisation, and scalability, while acknowledging challenges such as secure integration of private data and potential errors in automated systems. The authors argue that, with proper implementation, serverless architectures can provide robust solutions for IoT metadata processing, enabling improved performance, reliability, and economic efficiency in modern IoT ecosystems.

By addressing both theoretical and practical aspects, the study offers valuable insights for researchers and practitioners seeking to harness the power of serverless systems for IoT applications. The findings underscore the transformative potential of cloud-based, serverless infrastructures in achieving efficient and scalable data management for IoT-driven industries.

The First Hundred Years of Women’s Theological Education in Cluj-Napoca
The initial topic of the study at hand addresses the beginnings. In terms of women’s education, one of the positive effects of the Reformation is the insistence on the widespread availability of the Bible, which was inevitably followed by the eradication of illiteracy among women. Following the Reformation, another argument emerged in favour of the importance of educating women in theology: society regarded women as a key role in raising children, so in order to raise their children educated in theology, their ability to do so became a priority. The second topic addresses the direct preconditions of the theological education of women, especially the changes in the 19th-century school history, which resulted in women’s admission to universities and opening up the opportunity for them to obtain degrees in higher education. Furthermore, the study presents the past hundred years of women’s education in theology in the Protestant educational centres of Cluj-Napoca – from the first enrolment, the first ordained woman minister up to the present time.
A Károli Gáspár Református Egyetem megalapításának története
Authors: LÁNYI Gábor
Published: December 2024

The History of the Foundation of Károli Gáspár Reformed University
Plans to found a Hungarian Reformed university in Transylvania were conceived during the reigns of princes Gábor Bethlen (1622) and Ákos Barcsai (1658, then at the initiative of János Apáczai Csere), but unfortunately external circumstances prevented the establishment of such a university. At the end of the 18th century, the idea was raised again in Pest (József Vay, 1796). However, the circumstances made it only possible to establish a joint Evangelical-Reformed theological faculty (Pál Török, Theological Academy of Pest, 1855). In 1993, under the more favourable conditions of the regime change, the longed-for university could be founded, with the merger of the Theological Academy and the Teachers’ College of Nagykőrös and the establishment of a faculty of humanities in Budapest. Our study presents the circumstances, processes, debates, and key personalities behind the founding of the university 30 years ago.

The Relationship of Religiosity with Mental Health and Well-Being during the COVID-19 Pandemic
The relationship between religiosity and mental health is a popular area of research in the psychology of religion. A considerable body of research supports the positive effects of religion on both psychological and physical well-being. The present research aimed to explore the links between these areas during the coronavirus pandemic. In our quantitative online study, we analysed data from 2,269 (1,022 men and 1,407 women, mean age 43 years, SD = 16–95 years) healthy individuals aged 16 years and over. A complete test battery was used for the analysis, including the DUREL Religiousness Questionnaire and the PHS-WB General Well-Being Scale, as well as a question on faith in God. Our results show that our dimensions of religiosity: belief in God, institutional and non-institutional religiosity, and intrinsic orientation are positively related to two dimensions of general well-being, mental and social well-being. Those who regularly practise their religion in an institutional setting, report significantly better mental and social well-being than those who are not regular religious practitioners.

Receptive Community or a Different Kind of Pastoral Care? – Workshop
Inclusive attitude can be learned and taught at the same time. We are provided with plenty of chances to acquire it personally, as individuals, particularly in the context of the natural encounters and relationships born out of the everyday realities of our lives. However, it can be learnt as a community as well – how to become a home to those who are “special” in a certain way. As a pastoral care worker, too, taking those internal and external steps leading from compassion to participation is a key learning task of acceptance and inclusion.

Rice (Oryza sativa L.), the traditional food for the Bangladeshi population, serves as a significant disclosure pathway of cadmium for humans. A few studies have explored cadmium levels in different rice varieties in Bangladesh. The study examined the impacts of cadmium pollution on growth, and productivity and evaluated the varietal resistance. Cadmium was added to the soil at 15 mg/kg. A pot experiment involving nine T-aman rice varieties was conducted at 0 (control) and 15 mg Cd/kg soil. Cadmium toxicity led to reduced quantity and quality of rice production. Cadmium pollution enhanced the grain cadmium levels while depleting the amounts of nitrogen, phosphorus, potassium, and sulphur. Local varieties and BRRI dhan72 exhibited the lowest grain cadmium concentration when grown with 0 mg/kg cadmium in the soil, while BRRI dhan52 (2.94 mg/kg) showed the highest with 15 mg/kg cadmium in the soil. The average daily intake of cadmium from rice grain was higher with 15 mg/kg cadmium addition. All rice varieties showed high HQ (Hazard Quotient) and ILCR (Incremental Lifetime Cancer Risk) values under 15 mg/kg cadmium in soil. The HQ and ILCR values ranged from 2.39 to 16.09, and 0.36 × 10−4 to 2.41 × 10−4, respectively, for a Bangladeshi adult due to the application of 15 mg/kg cadmium. The highest HQ (16.09) and ILCR (2.41×10−4) values were obtained for BRRI dhan52 at 15 mg/kg cadmium for adults. The susceptibility of the varieties due to 15 mg/kg cadmium may be ranked as BRRI dhan52>Binadhan-23>BRRI dhan79>Binadhan-12>BRRI dhan62>BRRI dhan71>Zeeramala>BRRI dhan72>Local HYV.

In this review, the impact on the ballistic protection properties for some materials used in the military field was analysed, in relation to the improvement of mechanical and microstructural properties.

The main objective was the ballistic protection materials with the potential to be used as ballistic protection for applications such as bulletproof vests.

In the addition to the evaluation related to improvement of the considered material proprieties, the impact on the improvement of the ballistic protection grades was also evaluated in relation with the test standards such as: NIJ, VPAM, NATO STANAG 4569 (Association of Test Laboratories for Attack Resistant Materials and Constructions, 2024; NATO Standardization Office NSDD, 2022; NIJ, 2023).

The evaluation that is subject of this paper, it consists of two types of processes: thermal coating using Atmospheric Plasma Spray (APS) method and coatings using Cold Spray method.

Using these methods of improving the mechanical properties, the impact on ballistic protection grades was highlighted, considering both standards:(NIJ) Standard 0101.07 (NIJ, 2023) and NIJ Standard 0123.00 (NIJ, 2023), which are defined in alignment with National Institute of Justice from USA. The impact of the materials was also evaluated in relation to the standard VPAM “Association of Test Laboratories for Attack Resistant Materials and Constructions” (Association of Test Laboratories for Attack Resistant Materials and Constructions, 2024) with intended use in Europe and also standard “NATOStandardization Agreements” AEP-55 STANAG 4569 (NATO Standardization Office NSDD, 2022).
An Unsupervised Anomaly Detection in Electricity Consumption Using Reinforcement Learning and Time Series Forest Based Framework
Authors: Ghanim Jihan , Awad Mariette
Published: December 2024

Anomaly detection (AD) plays a crucial role in time series applications, primarily because time series data is employed across real-world scenarios. Detecting anomalies poses significant challenges since anomalies take diverse forms making them hard to pinpoint accurately. Previous research has explored different AD models, making specific assumptions with varying sensitivity toward particular anomaly types. To address this issue, we propose a novel model selection for unsupervised AD using a combination of time series forest (TSF) and reinforcement learning (RL) approaches that dynamically chooses an AD technique. Our approach allows for effective AD without explicitly depending on ground truth labels that are often scarce and expensive to obtain. Results from the real-time series dataset demonstrate that the proposed model selection approach outperforms all other AD models in terms of the F1 score metric. For the synthetic dataset, our proposed model surpasses all other AD models except for KNN, with an impressive F1 score of 0.989. The proposed model selection framework also exceeded the performance of GPT-4 when prompted to act as an anomaly detector on the synthetic dataset. Exploring different reward functions revealed that the original reward function in our proposed AD model selection approach yielded the best overall scores. We evaluated the performance of the six AD models on an additional three datasets, having global, local, and clustered anomalies respectively, showing that each AD model exhibited distinct performance depending on the type of anomalies. This emphasizes the significance of our proposed AD model selection framework, maintaining high performance across all datasets, and showcasing superior performance across different anomaly types.

Co-creation-based governance is considered to be an element of good governance, and Lithuanian public governance innovations are also linked to this principle. Thus, the aim of the study is to assess the experience of participation of different groups of stakeholders in the National Agreement on Forests, based on the co-creation principle. The main goals of the research are to identify problematic aspects of the application of the co-creation principle, and to provide guidelines for the effective implementation of the co-creation principle in public policy processes. The study explores the practicalities of applying the co-creation principle and presents data of the interviews with representatives of interest groups from different sectors (economic, ecological and social) and politicians involved in the National Agreement on Forests. The study also describes the results of a secondary data analysis, based on the European Social Survey, which has helped to identify possible reasons for the failure of the agreement.
