Published: October 2023

This study investigated the multi-criteria task of optimizing the operating modes of cathodic protection stations (CPS), considering monitoring data, geological conditions at the pipeline installation site, climatic or seasonal changes, and other factors. The relevance of this research is associated with a comprehensive solution to the problem of increasing the durability and reliability of trunk pipelines to reduce accidents at their facilities by ensuring the efficiency of electrochemical protection (EChP) systems. The problems of existing EChP systems are analyzed, where the elimination of anode zones ("lack of protection") due to cathodic polarization is carried out without operational consideration of environmental conditions, as a rule, with a margin in terms of protective potential, which often leads to "overprotection", resulting in increased power consumption, gas formation on the metal surface, and detachment and wear insulation of pipelines. The aim of this research is to create a method for optimal regulation of the operation modes of the main pipelines and an adaptive electrochemical protection system that provides control and parameter management of cathodic protection stations, considering changes in external conditions on individual linear sections of main pipelines. Tasks: to develop an adjustment method for finding the effect of the CPS on the value of potentials at control points along the pipeline route; to develop a multicriteria optimization model for regulating the operation modes of the CPS; and to provide an example of testing the method of optimal regulation on the objects of the linear part of the existing main gas pipeline. The following results were obtained. A method is proposed for determining the effect of CPS operating modes on the value of potentials at control points in the mode of interrupting the protection current of other stations. An optimization model was formed according to the criterion of uniformity of the distribution of the protective potential "pipe-ground" along the pipeline route and according to the criterion of the minimum total protective current of all CPSs on a given section of the main pipeline. Conclusions. The scientific novelty of the results obtained is associated with the development of an original optimization method that allows scientifically determining the operation modes of the CPS to ensure the protection of the main pipeline both in time and length with reduced operating costs and adaptability to changes in climatic, seasonal, and geological conditions at the pipeline installation site. The effectiveness of the proposed approach is illustrated by the regulation of the parameters of the CPS based on the monitoring data of the section of the main gas pipeline of the oil and gas complex of the Republic of Kazakhstan.
Analysis of pollutants in air within the territory of Ukraine using geostatistical methods
Authors: Butenko Olga , Topchiy Anna
Published: October 2023

Air quality has recently been of great concern, as it directly affects people's lives. Continuous monitoring of atmospheric air quality and forecasting the dynamics of its changes are essential steps in assessing its current state and determining the concentration of pollutants. Therefore, the development of an effective system for assessing and forecasting the quality of atmospheric air has become one of the most important tasks. The subject matter of this article is geostatistical methods for air quality analysis. The goal is to analyze pollutants in the air over Ukraine's territory from 1990 to 2021. The dataset on air pollutants was provided by the State Statistics Service of Ukraine in the form of aggregated tables, which were initially processed for subsequent modelling. Cartographic modelling of pollutants was performed using geostatistical methods. As a result, this study presents 13 cartographic models showing the spatial distribution of air pollutants for different regions of Ukraine. However, because of the lack of official information on the presence of military actions, the results of geostatistical methods cannot be interpreted in the context of the military situation in the eastern part of the country. Information about military actions can be gathered from various sources, but this would require a considerable time and effort to structure and systematize the dataset. Conclusions. The method considered in this study cannot simultaneously consider multiple parameters, such as the value of pollutant indicators and the presence of military actions. Additional methods, such as graph theory and regression analysis, are employed to obtain quantitative assessments of the modelling results considering all factors influencing the environmental condition. The chosen method is a straightforward tool for solving environmental problems. Thanks to available GIS systems like ArcGIS Pro, visualization of the applied geostatistical and mathematical methods is possible. The cartographic models presented in this study cover the entire territory of Ukraine and have administrative boundaries depending on the location of the pollutant collection station.

Published: October 2023

Today, there is a contradiction between the rapid increase in the complexity and size of modern software while increasing responsibility for the performance of their functions, the increasing requirements of customers and users to the quality and efficiency of software use and the imperfection of models, methods, tools of predicting software quality at the early stages of the life cycle.Therefore, the task of predicting the software quality level based on requirements is relevant. The aim of this study is to solve this task by developing information technology for prediction software quality levels based on requirements. The proposed information technology for prediction software quality level based on requirements provides analysis of quality attributes in requirements, reflects the dependence (equations) of quality characteristics on attributes, forms a quantitative assessment of quality characteristics, reflects the dependence (equation) of quality on its characteristics, forms a quantitative assessment of quality, performs quality level prediction, provides all the listed services simultaneously and the model, methods, and tools underlying the IT belong to common methodological approaches and are integrated. The developed system of predicting the software quality level based on requirements provides the user with predicted estimates of eight software quality characteristics, geometric interpretation of the software quality characteristics’ values, a comprehensive indicator of the predicted software quality, and a conclusion about the future software quality level. On the basis of this, it is possible to compare sets of requirements for software and make a reasonable choice of a set of requirements for further implementation. The information technology and the system of predicting the software quality level based on requirements, developed in this paper, provide the possibility of comparing sets of requirements for software, justified selection of requirements for further implementation of quality software (as experiments have shown, this is only one of the four proposed sets), and rejection or revision of unsuccessful sets of requirements that cannot be used to develop quality software.

Published: October 2023

Randomized controlled clinical trials are frequently hardly feasible in patients with orphan disorders given the limited number of potential participants and variablity of clinical manifestations and the course of disease. Registry data, particularly for rare diseases, provide additional information regarding long-term treatment effectiveness and safety. The year 2021 marked the 20th anniversary of the Fabry Outcome Survey (FOS), an international, multicenter, observational registry (NCT03289065). The aim of FOS was to study Fabry disease, an X-linked lysosomal storage disorder caused by mutations in the galactosidase alpha (GLA) gene that result in reduced or absent a-galactosidase A activity and sphyngolipids accumulation in the various tissues. As of January 2021, 4484 patients with Fabry disease have been enrolled in FOS from 144 centers across 26 countries. Analyses of FOS data has confirmed the efficacy and safety of enzyme replacement therapy with agalsidase alfa and its favorable impact on the course of Fabry disease and mortality. FOS data have also shown the advantages of prompt treatment that was more effective in prevention of cardiovascular and renal events regardless of type of disease.
Committer Assessment Practice in Blockchain Project: A Systematic Literature Review
Authors: Abd Wahab Dr. Alawiyah , H. Ibrahim Huda , SarkinTudu Shehu
Published: October 2023

As Blockchain projects gain popularity among developers, the number of patched codes rapidly increases. With such growth, it is difficult for the few committers to maintain it in a timely manner. Subsequently, the community is always in search of new committers. This highlights the imperative importance of committer assessment decisions towards the success of Blockchain. However, the practices come with risks whereby new committers may harm the project. For example, a new committer may initiate a hard fork that splits a project. Numerous systematic literature reviews have investigated developer turnover’s impact on open-source software (OSS) projects. These studies mainly focused on aspects such as community participation, engagement, and motivation. However, previous reviews often overlooked committer assessment practices, particularly in the context of Blockchain projects. Although Blockchain operates as OSS, its distinct attributes, such as decentralisation and cryptography, justify the need for a dedicated review. Therefore, the objectives of this review are to 1) identify committer assessment practices, 2) identify problems in committer assessment, 3) identify existing factors in committer assessment, and 4) suggest some possible research topics. These goals were achieved through a systematic review of literature published between 2010 and 2022. The findings suggest that previous assessment models are useful but mainly focus on technical factors. The results also indicate that studies focusing on behavioural tendencies, which influence human activities, have so far been neglected. Finally, the paper concludes by charting potential open research opportunities.
Decreased Functional Magnetic Resonance Imaging Activity in the Hippocampus in favor of the Caudate Nucleus in Older Adults Tested in a Virtual Navigation Task

Published: October 2023

The neuroimaging literature has shown consistent decreases in functional magnetic resonance imaging (fMRI) activity in the hippocampus of healthy older adults engaged in a navigation task. However, navigation in a virtual maze relies on spatial or response strategies known to depend on the hippocampus and caudate nucleus, respectively. Therefore, since the proportion of people using spatial strategies decreases with normal aging, we hypothesized that it was responsible for the observed decreases in fMRI activity in the hippocampus reported in the literature. The aim of this study was to examine the effects of aging on the hippocampus and caudate nucleus during navigation while taking into account individual navigational strategies. Young (N = 23) and older adults (N = 29) were tested using fMRI on the Concurrent Spatial Discrimination Learning Task, a radial task that dissociates between spatial and response strategies (in Stage 2) after participants reached criteria (in Stage 1). Success on Stage 2 requires that participants have encoded the spatial relationship between the target object and environmental landmarks, that is, the spatial strategy. While older adults required more trials, all participants reached criterion. fMRI results showed that, as a group, young adults had significant activity in the hippocampus as opposed to older adults who instead had significant activity in the caudate nucleus. Importantly, individual differences showed that the older participants who used a spatial strategy to solve the task had significant activity in the hippocampus. These findings suggest that the aging process involves a shift from using the hippocampus toward the caudate nucleus during navigation but that activity in the hippocampus is sustained in a subset of healthy older adults engaged in spatial strategies.
Age-related differences in prefrontal-hippocampal connectivity are associated with reduced spatial context memory
Authors: Ankudowich Elizabeth , Pasvanis Stamatoula , Rajah M. Natasha
Published: October 2023

Altered functional connectivity between dorsolateral prefrontal cortex (DLPFC), posterior hippocampus (HC) and other brain regions with advanced age may contribute to age-related differences in episodic memory. In the current fMRI study of spatial context memory, we used seed connectivity analysis to test for age-related differences in the correlations between activity in DLPFC and HC seeds, and the rest of the brain, in an adult life span sample. In young adults, we found that connectivity between right DLPFC and other prefrontal cortex regions, parietal cortex, precuneus, and ventral visual cortices during encoding was positively related to performance. Positive seed connectivity among these regions, and negative connectivity with posterior HC at retrieval was also positively correlated with retrieval accuracy in young adults. In older adults, activity in right DLPFC was positively correlated with activity in this same set of brain regions, and with posterior HC during encoding and retrieval. Interestingly, this pattern of seed connectivity in older adults was negatively correlated with retrieval accuracy. Thus, age-related differences in context memory may be related to altered frontal-parietal and visual cortical interactions with posterior HC.

Aging is associated with episodic memory decline and alterations in memory-related brain function. However, it remains unclear if age-related memory decline is associated with similar patterns of brain aging in women and men. In the current task fMRI study, we tested the hypothesis that there are sex differences in the effect of age and memory performance on brain activity during episodic encoding and retrieval of face-location associations (spatial context memory). Forty-one women and 41 men between the ages of 21 to 76 years participated in this study. Between-group multivariate partial least squares (PLS) analysis of the fMRI data was conducted to directly test for sex-group differences and similarities in age-related and performance-related patterns of brain activity. Our behavioural analysis indicated no significant sex differences in retrieval accuracy on the fMRI tasks. In relation to performance effects, we observed similarities and differences in how retrieval accuracy related to brain activity in women and men. Both sexes activated dorsal and lateral prefrontal cortex (PFC), inferior parietal cortex (IPC) and left parahippocampal gyrus (PHG) at encoding and this supported subsequent memory performance. However, there were sex differences in retrieval activity in these same regions and in lateral occipital-temporal and ventrolateral PFC. In relation to age effects, we observed sex differences in the effect of age on memory-related activity within PFC, IPC, PHG and lateral occipital-temporal cortices. Overall, our findings suggest that the neural correlates of age-related spatial context memory decline differ in women compared to men.

Published: October 2023

Major hardware/software changes to MRI platforms, either planned or unplanned, will almost invariably occur in longitudinal studies. Our objective was to assess the resulting variability on relevant imaging measurements in such context, specifically for three Siemens Healthcare Magnetom Trio upgrades to the Prismafit platform. We report data acquired on three healthy volunteers scanned before and after three different platform upgrades. We assessed differences in image signal [contrast-to-noise ratio (CNR)] on T1-weighted images (T1w) and fluid-attenuated inversion recovery images (FLAIR); brain morphometry on T1w image; and small vessel disease (white matter hyperintensities; WMH) on FLAIR image. Prismafit upgrade resulted in higher (30%) and more variable neocortical CNR and larger brain volume and thickness mainly in frontal areas. A significant relationship was observed between neocortical CNR and neocortical volume. For FLAIR images, no significant CNR difference was observed, but WMH volumes were significantly smaller (-68%) after Prismafit upgrade, when compared to results on the Magnetom Trio. Together, these results indicate that Prismafit upgrade significantly influenced image signal, brain morphometry measures and small vessel diseases measures and that these effects need to be taken into account when analyzing results from any longitudinal study undergoing similar changes.

IDEOLOGY IN INDONESIAN POLITICAL PARTY ANTHEMS: A STYLISTIC ANALYSIS AT THE LEXICOGRAMMATICAL LEVEL
Authors: Lubis Donal Fernado , Bowo Tri Arie
Published: October 2023

Political parties are a forum for Indonesian people from various ideological backgrounds as channels for the aspirations of a pluralistic society. The party's ideology is embodied in the vision and mission that the party aspires to when domination is obtained after the General Election is held. In this research, the anthem lyrics of the top three political parties, based on the 2019 legislative elections, were taken as the data and studied through a stylistic approach at the lexicogrammatical level to figure out the ideology in the realization of the vision and mission of the political parties. The method of the analysis applied descriptive qualitative through transitivity analysis in order to reveal the lexical and grammatical construction in the lyric. The typical processes used in each anthem characterized the cognitive frame of how the political parties set their vision and orientation towards the nation goals. It was found that the use of stylistic devices came in low frequency, including epizeuxis, parallelism, imagery, metaphor, symbolism, asyndeton and anaphora. The construction of clauses in the anthem lyrics has a significant impact in expressing the goals of political parties ideologically, so that the results of this study are expected to be an alternative reference that provides a paradigm for the voting community during the election period

Intracranial arteriosclerosis: determinants and clinical consequences
Authors:   , van den Beukel Tim Cornelis
Published: October 2023

Vaatverkalkingen, of arteriosclerose, zijn afzettingen van mineralen in het vaatstelsel, meestal in de vorm van hydroxyapatiet. In de vaatwant komen ze met name voor in atherosclerotische plaque in de tunica intima, of in de omliggende lamina elastica interna (IEL) of tunica media. In Hoofdstuk 1 van dit proefschrift wordt een overzicht gegeven van de beschikbare kennis over intracraniële arteriosclerose en beschrijft dat er een opvallende schaarste is aan kennis over arteriosclerose in de vertebrobasilaire arteriën (VBAC). Hierom hebben we in Hoofdstuk 2 de prevalentie van en de risicofactoren voor VBAC onderzocht, waarin we vonden dat het bij ongeveer 25% van de patiënten voorkwam. Met betrekking tot risicofactoren vonden we dat, naast leeftijd, obesitas sterk geassocieerd was met VBAC.

Pseudoxanthoma elasticum (PXE) is een ziekte waarbij veel vaatverkalking voorkomt. PXE wordt in de medische literatuur vaak aangehaald als modelziekte om de effecten van geïsoleerde IEL verkalking te bestuderen. In Hoofdstuk 3 voerden we een patiënt-controle studie uit waarin we de belasting van intracraniële atherosclerotische laesies in de slagaders van de Cirkel van Willis vergeleken tussen PXE-patiënten en leeftijd- en geslacht gematchte controles. We vonden dat de belasting en verdeling van intracraniële atherosclerotische laesies vergelijkbaar waren tussen PXE-patiënten en controles. Daarnaast is het zo dat er gerandomiseerde klinische trials worden gepland in PXE patiënten om medicatie te testen die vaatverkalking afremt. Daarom voerden we in Hoofdstuk 4 een onderzoek uit met herhaalde metingen van verkalkingen door het gehele lichaam bij PXE, waarin we de specifieke ontwikkeling van vaatverkalking over de tijd hebben gekarakteriseerd. Dit is kritieke informatie voor de juiste planning en evaluatie van de eerder genoemnde gerandomiseerde studies.

In Deel 3 werd een poging gedaan om intracraniële arteriosclerose verder aan te tonen als een belangrijke risicofactor voor beroerte en dementie. In Hoofdstuk 5 is specifiek gekeken naar subtypes van intracraniële verkalking van de a. carotis (ICAC), namelijk atherosclerotisch intima-verkalking versus verkalking in de IEL, en het risico op beroerte. We vonden dat beide subtypes het risico op een beroerte verhoogden, waarbij verkalking van de IEL het grootste risico met zich meedroeg. In Hoofdstuk 6 is zowel gekeken naar ICAC, ICAC subtypes, en VBAC en het risico op dementie. We vonden dat beide subtypes van ICAC en alleen grote hoeveelheden VBAC het risico op dementie verhogen. Daarnaast vonden we middels een mediatie-analyse dat een deel van dit risico werd verklaard door toegenomen schade aan de kleine vaten (witte stof hyperintensiteiten) als mediator.
In de toekomst zou meer robuust bewijs met betrekking tot de vermeende causale verbanden tussen intracraniële arteriosclerose en klinische uitkomsten die blijken uit dit proefschrift moeten volgen uit goed opgezette gerandomiseerde klinische onderzoeken waarbij intracraniële arteriosclerose wordt behandeld.
