Deep Sentiment Classification in COVID-19 Using LSTM Recurrent Neural Network
Authors: Khurana Jatin
Published: February 2025

Users (people/patients) concerned about health concerns have an easy outlet
in online medical forums along with other public social media on the Internet. The
World Health Organization declared a global public health emergency in response to
the emergence of a new coronavirus (infection which causes the disease termed
COVID-19) in late December 2019. In this research, we employed a natural language
processing (NLP) technique based on topic modeling to automatically extract COVID19-related talks from social media and discover numerous concerns linked to COVID19 from public viewpoints. As an added bonus, we look into the possibility of
employing a long short-term memory (LSTM) recurrent neural network to accomplish
the same task with COVID-19 remarks. Our research highlights the value of
incorporating public opinion and appropriate computational approaches into the
process of learning about and making decisions on COVID-19. The trials also showed
that the study model was able to reach an accuracy of 81.15 percent, which is greater
than the accuracy attained by many other popular machine-learning methods for
COVID-19 sentiment classification.
Investigating the Use of Data Mining for Knowledge Discovery
Authors: Bisht Sover Singh
Published: February 2025

The practice of “lifelogging” involves documenting an increasing amount of
one's subjective everyday experience with the intention of using the recordings in the
future as a memory aid or the foundation for data-driven self-development. Therefore,
the usefulness of the generated lifelogs depends on the lifeloggers' ability to efficiently
sift through them. The logs' intrinsic multi-modality and semi-structure allow them to
combine data from a variety of sources, including cameras and other wearable physical
and virtual sensors. As a result, expressing the data in a graph structure allows for the
effective capturing of all created interrelations. Alternative methods must be developed
to capture the higher-level semantics because it is impossible to manually or
mechanically annotate each entry with a significant amount of semantic context. We
describe an Improved Life Graph (ILG), a first method for building a Knowledge
Graph-based lifelog representation and retrieval solution, which can capture a lifelog in
a graph structure and augment it with external data to help with the connection of
higher-level semantic information.
An experimental investigation on dense bituminous macadam (IRC- grading 2) mixes with coal ash
Authors: SONAWANE Sagar Kailas
Published: February 2025

Abstract. India is a developing country, and the main source of power generation is coal based thermal power plants, contributing to more than 70% of the total electricity generated in the country [1]. The predominant byproduct of a coal-fired thermal power station consists of bottom ash and fly ash. Coal-burning in thermal power plants releases gaseous and particulate pollution into the environment affecting various aspects of the environment & human health, leading to premature deaths and illnesses [2, 3]. The present study investigates the impact of coal ash, more specifically fly ash & bottom ash on dense bituminous macadam mixtures of Indian Roads Congress (IRC) - Grading II when employed as a substitute for a portion of the fine aggregates & fillers. DBM specimens were made using four coal ash percentage of 0%, 9%, 18% and 27%, with the fly ash content keeping constant at 6% by weight in the mix as a filler. The optimal composition was chosen following an analysis of the outcomes of Marshall test. The findings demonstrated that the partial replacement of fine aggregates with coal ash in DBM mixes resulted in a moderately adverse impact on the Marshall tests parameters. By utilizing coal ash in DBM mixes, the present study partly solves the problem of heavy dumping & solid waste disposal problem of coal ash on land leads to sustainable road pavement construction.
Analyzing locations prone to causing road crash injuries and fatalities in Saudi Arabia
Authors: ALMUTAIRI Omar
Published: February 2025

Abstract. This study proposes a systematic approach to analyzing crash data and identifying high-crash areas in Saudi Arabia’s intercity road network. The approach employs a five-stage process involving data preparation, cluster identification using density-based clustering algorithm DBSCAN, predictive modeling for fatalities and injuries, data aggregation, and cluster ranking. This research’s results reveal that nearly a quarter of crashes are concentrated within clusters. The predictive model confirms the expected relationship between vehicle type, time of day, and crash severity. By quantifying excess fatalities and injuries in these clusters, safety analysts can prioritize locations that should receive targeted interventions. This research offers a practical framework for enhancing road safety. By automating the proposed approach and providing clear visualizations, safety analysts can efficiently identify high-risk areas and implement data-driven countermeasures. This study represents a significant step toward reducing crashes and their consequences.
Investigating top-down cracking of pavement in recycled waste plastic asphalt
Authors: ABEJIDE Samuel
Published: February 2025

Abstract. This study investigates a new approach for the use of an alternative sustainable wearing course material on flexible pavement roads (recycled asphalt plastic pavement). Highway infrastructure plays a major key role in the domestic transportation of people, goods and services within the community and from a national perspective. Thus, highway infrastructure provides provincial and local accessibility, which promotes the growth and development of the economy. For this reason, there is a need to develop a sustainable approach to increase the efficiency of transportation infrastructure. The purpose of this study was to evaluate top-down fatigue cracking failure mode of asphaltic wearing courses for use in in pavement overlays, at high traffic intersection points and on parking sections using dual tire loads in finite element analysis. The process of developing alternative mixing materials is initiated by the need to provide a stable mixture for use on field sections different from cold mix or conventional hot mix (HMA) materials, which is subjected to stripping delamination mode with increasing moisture content. In this study, it was observed that the bonds formed between the molten plastic material has the potential to bind the bitumen and the aggregates together as a homogenous material in such a way that, when hardened at reduced temperatures, the mix is able to form a stronger bonded material that is semipervious and allows drainage of moisture or water across the surface of the asphalt plastic layer. This study adopts an alternative approach to the design of an ultrathin film asphalt concrete porous pavement layer for use in pavement surface wearing course and high-density traffic roads considering the effects of increasing temperature and moisture absorption on the asphalt plastic pavement mix.
A DEMATEL-based method for developing and assessing key performance indicators for construction projects
Authors: SALMAN ALAA
Published: February 2025

Abstract. Construction projects present unique challenges compared to other project types, given their inherent risks, lengthy timelines, substantial budgets, and significant social, environmental, and safety implications. Despite these complexities, the ultimate deliverables may not always meet the expectations of end users or owners. This project aims to address this issue by initially developing key performance indicators (KPIs) and subsequently creating a project performance card (PPC) tailored specifically for construction projects. Eight indicators have been identified to assess the performance of these projects upon completion. These indicators will be integrated to derive a final score and issue a project performance card using the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method. The results consist of a Relationships Digraph, which identifies the causal and recipient indicators, and a PPC illustrating the KPIs along with the project's final performance score. To elucidate the developed models and interpret the results for future construction projects, a case study is provided. Project Performance Analyzer (PPA), an automated online tool, has been developed to implement the current methodology and generate a project report card that illustrates the relationships among project indicators. This research significantly contributes to pinpointing the weaknesses in construction project performance and comparing their performance levels to other project types.

Authors: PRASETYO Ryan Faza
Published: February 2025

Abstract. One of the success factors in project planning is the accuracy of the risk identification process. Traditionally, this process involves experienced individuals to effectively identify risks. However, not all projects have access to experienced resources for efficient risk identification. The implementation of Virtual Reality (VR) has the potential to provide a virtual and spatial experience, allowing users to feel as if they are in the actual field conditions. This study aims to evaluate the application of VR in the risk identification process by assessing the relevance and comparing the risks identified using VR with findings from previous research. The method used involves summarizing responses from participants to determine the dominant risks successfully identified by bring respondent to virtual reality environment that representing real condition of construction site utilizing integration of SketchUp modelling and VR Sketch Software. The research results indicate that the most frequently mentioned risks are related to falling from heights and being struck by materials or other objects on construction projects. These findings align with previous studies, which highlight that falling from heights and being struck by materials are significant risk sources leading to fatalities in construction projects, particularly in Indonesia.

Simultaneous brine and CO2 utilization in construction material production: A life cycle assessment
Authors: ZUKAITYTE Aiste
Published: February 2025

Abstract. Economic development has led to a significant increase in CO2 emissions, resource depletion, and freshwater demand. In arid regions, seawater desalination has been employed as a reliable source of freshwater. However, the environmental challenges associated with reject brine management have been increasingly scrutinized for their adverse effects on adjacent ecosystems. Recent research efforts have explored the potential for simultaneous treatment of CO2 emissions and reject brine, by recovering valuable minerals and converting waste into a resource. This study presents a life cycle assessment (LCA) of construction material produced using industrial byproducts locally sourced in the Gulf region. The production process involves two main stages: CO2 absorption from flue gas in an alkaline solution and subsequent ex-situ mineralization. Desalination reject brine is used as a steady source of dissolved Ca²⁺ and Mg²⁺, contributing to a circular. The developed construction product exhibits superior mechanical performance compared to industrial standards. The presented LCA examines environmental impacts, including climate change, resource depletion, and water use. The new material contains approximately 30 wt.% sequestered CO₂. The total quantified environmental impacts include 0.391 kg CO₂ eq. for climate change, 0.23 kg oil eq. for fossil depletion, and 0.021 m³ for freshwater consumption per kilogram of plasterboard. These findings underscore the potential of this innovative process to provide sustainable construction alternatives while mitigating the impacts of CO₂ emissions and waste from desalination.

Platelet indices as unequivocal markers of active disease in patients of non-radiographic axial Spondyloarthritis: Protocol for an observational study (Preprint)
Authors: Agrawal Abhijeet , Acharya Sourya , Bhagawati Jahnabi
Published: February 2025

BACKGROUND

Spondyloarthritis (SpA) is divided into axial and peripheral subtypes. The axial subtype further consists of ankylosing spondylitis (AS) or radiographic axial SpA (r-axSpA) and non-radiographic axial Spondyloarthritis (nr-axSpA). Though AS and nr-axSpA share some common features, nr-axSpA lacks x-ray-based sacroiliitis as defined by modified New York criteria. Disease activity in either of them is measured via CRP levels or MRI imaging of the pelvis. A person with active disease can have normal CRP and/or MRI findings, especially in nr-axSpA. These groups of patients are frequently negative for existing objective markers of inflammation. Immune system activation during inflammation has been shown to alter the platelet maturation and morphology reflected by platelet indices.

OBJECTIVE

In this study, we will determine if platelet indices are reliable biomarkers in measuring disease activity in patients with non-radiological Axial Spondyloarthritis.

METHODS

All patients diagnosed with Axial Spondyloarthritis per ASAS Criteria will be included in this study. Patients will be divided into two case groups: patients without radiographic sacroiliitis as non-radiographic axial Spondyloarthritis(nr-axSpA), with radiographic sacroiliitis as Ankylosing spondylitis(AS) and normal individuals will be kept as controls to compare and correlate the platelet indices such as platelet count, platelet grit, mean platelet volume and platelet distribution width with CRP and MRI findings of AS with nr-axSpA.

RESULTS

At the end of study we would be able to correlate if platelet indices are better biomarkers of active disease in patients of nr-axSpA.

CONCLUSIONS

If platelet indices prove to be better markers of active disease in nr-AxSpA then there exists a gap in clinical practice while evaluating such patients and these markers should be included in routine evaluation of nr-AxSpA patients as they usually have normal CRP and often lack signs of Sacroiliac joint inflammation on MRI.

Exploring the Structural Spread of Close-Mindedness as an Epistemic Vice in Indonesia
Authors: Arrafi Silitonga Ferris , Sandi Pratama Herdito
Published: February 2025

The post-Suharto era in Indonesia, which spans over 26 years and encompasses numerous leadership changes, has been marked by significant democratic challenges. The period is defined by the rise of populism, increasing polarization, and institutional resistance to open discourse. Sensitive discussions regarding the principles and ideologies of the state are often met with reluctance or outright rejection by governmental institutions. These tendencies reflect a deeper structural issue: the intellectual vice of close-mindedness, as examined through the lens of vice epistemology. This paper argues that close-mindedness operates not only at an individual level but also as a systemic issue entrenched within institutional frameworks, creating a feedback loop between political structures and societal attitudes. The paper examines the relationship between institutional resistance and societal polarization, shedding light on how these elements reinforce one another. Additionally, it investigates the cultural and historical factors that have contributed to the perpetuation of close-mindedness as an epistemic vice in Indonesia’s governance and political culture. Left unaddressed, this structural vice threatens to undermine the integrity of Indonesia’s democracy and further deepen societal divisions. In its conclusion, the paper offers practical recommendations to break this cycle, emphasizing the need for fostering intellectual humility, strengthening democratic institutions, and encouraging open and critical public discourse to safeguard the nation’s democratic trajectory.

Published: February 2025

The increasing prevalence of decentralized multiagent systems has spurred interest in Federated Reinforcement Learning (FRL) as a privacy-preserving framework for collaborative learning. However, scaling FRL to multi-agent settings introduces significant challenges, particularly in communication efficiency, decentralized aggregation, and handling nonstationary environments. This survey explores recent advancements in Scalable Decentralized Multi-Agent Federated Reinforcement Learning (MA-FRL), with a focus on communication efficient strategies and decentralized aggregation techniques. We review key approaches such as selective agent communication, local model updates, and gradient compression, analyzing their impact on scalability, convergence, and performance trade-offs. Additionally, we highlight comparative insights into different methods, their limitations, and real-world applicability in decentralized systems such as autonomous vehicles and smart grids. By identifying open challenges, including robustness against adversarial attacks and adaptive communication mechanisms, we outline promising directions for advancing decentralized MAFRL.

Authors:   Far East State Agricultural University, Gavrilov Yu.A. , Gavrilova G.A. ,   Far East State Agricultural University
Published: February 2025

Acute indigestion in newborn calves are registered quite often and cause significant damage to
livestock. There are many different drugs offered for their treatment and prevention, but not all of
them have relevant therapeutic effect. Currently, special attention is paid to acute indigestion in newborn calves of autoimmune origin, for the treatment and prevention of which traditional drugs are
not suitable. Therapeutic and prophylactic drug developed on the basis of natural zeolites contains
prednisolone, ascorbic acid and succinic acid. Complex drug has antiinflammatory properties due to
the inclusion of prednisolone; antioxidant properties due to ascorbic acid. Succinic acid helps to
improve the energy supply of myocardial cells, liver and kidneys, has antihypoxic and antioxidant
effects, increases synthesis of ATP. Its use together with colostrum at a dose of 1.0 g/kg of body weight
during the first four days of life prevents the occurrence of acute indigestion in 81.7% of newborns.
The use of the drug for therapeutic purposes three times a day at a dose of 1.0 g kg of weight has a
therapeutic effect in 88.9% of cases. Therapeutic and prophylactic drug helps to increase the level of
total protein, albumins, glucose in the serum of calves, leads to a decrease in the activity of transamination enzymes, improve hematological parameters.

Published: February 2025

The research paper considers the possibility of correcting the oxidative stress of the calves’ organism by the oral introduction of the succinic acid. The animals were divided into 2 groups, and
each of them had 15 calves, as follows: the control group animals were kept under standard conditions; the experimental group in which animals had a daily oral intake of the succinic acid in a dose of 50 mg/kg. The efficacy of the drug was assessed by the levels of lipid hydroperoxides, diene conjugates, and malonic dialdehyde and by the activity of the main components of the antioxidant system
in the blood plasma of calves. It was found that the use of succinic acid in the experiment contributes
to a decrease in plasma lipid hydroperoxides by 23%, diene conjugates – by 17%, malonic dialdehyde
– by 20% as compared to the calves of the control group (p<0,05). When analyzing the effect of
succinate-containing preparation on the activity of antioxidant system components, it was shown that
the content of ceruloplasmin and vitamin E in the blood of animals was higher than similar indicators
in calves of the control group by 29% and 17%, glucose-6-phosphate dehydrogenase – by 21%, catalase – by 25% (p<0,05). Thus, the inclusion of succinic acid in the scheme of prevention of neonatal
diseases of calves should be considered pathogenetically justified, clinically justified and promising.

The article considers the patented design of a new forage harvester. Crawler forage harvester is
a harvesting machine that performs a continuous technological process of mowing, crushing, loading
or reloading operations. Their development was accompanied by intensive improvement of schemes,
mechanisms that ensure reliable performance of machines, their versatility and ease of operation.
Present-day harvesters do not provide non-stop operation when vehicle is changed. Non-stop work
is one of the most important conditions for their work at high speeds, especially on wetlands. The
innovation consists in installation of the additional grinding device in the receiving chamber of the
batch hopper of the screw press. Triangular projections, having sharp end directed to the additional
grinding device, are fixed on the back wall on the inner side of the receiving chamber of the batch
hopper of the screw press. The rear wall of the receiving chamber of the hopper is attached to it: one
side-on a hinge, and the other – with the help of adjusting rods. The crushed mass is pressed and fills
the polymer bag «big-bag». The full bag with pressed mass is disconnected, closed and dropped at
the end of the field or swath, depending on the yield and furrow length. Transportation of soft containers to the storage place is carried out by special transport-a car with an enlarged platform and
a handling device.

the varieties of the collection nursery for the years 2018-2019. The object of the research in the collection
nursery: 110 varieties of domestic and foreign selection, - Fresko variety as a standard. Varieties of potato,
included in hybridization, have been identified according to a complex of economically valuable traits: Alvara,
Bellarosa, Vasilyok, Vulkan, Geyser, Elizaveta, Zhukovsky Ranniy, Karina, Rannespely, etc. 37 varieties of
potato have been singled out for their increased productivity (447 - 864 g / bush). The highest content of
vitamin C (4.5-9.5 mg%) was noted in the varieties - Ballarosa, Madeline, Monoliza. The following varieties
had an increased content of starch and dry matter: Visa, Vasilyok, Otrada, Ryabinushka, Alvara, Pamyati
Rogacheva, Kamchatka, Lazar, Velikan 13.5-16.3 and 18.1-21.5%, respectively. For the period of years 2011-
2019, 59 varieties and 5 hybrids were used in hybridization as maternal varieties selected at the All-Russian
Research Institute of Plant Industry (Research Institute of Plant Genetics) named after N.I. Vavilov., 20 varieties and 1 interspecific hybrid (All-Russian Research Institute of Plant Industry) were involved as pollinators,
7618 flowers were pollinated, 434 hybrid berries were set (produced). The percentage of successful crosses
amounted to 5.7. As the result of hybridization and breeding selection, medium-early varieties Vulkan and
Geyser were created and entered into the State Register of Protected Selection Achievements in years 2012
and 2014. The variety of potato Severyanin has been undergoing the State Variety Testing since 2019. Promising hybrids 87-59-07, 84-4-07, 56-2-06 have been obtained. They have been undergoing state testing for
resistance to cancer (Dalem pathotype) and golden potato cyst-forming nematodes (pathotype R01).

Cat behavioral deviations are quite common clinical cases of pet owners’ reason to visit the clinic.
In turn, the development of behavioral deviations is often observed against the background of crowded housing
and chronic stress in pets. The most common pathologies are idiopathic cystitis, dirty and untidy behavior,
tagging, various kinds of stereotypes, and so on. Dejection and untidy, dirty behavior can lead to a break in the
relationship between the owner and the pet. As a result, many dogs and cats become homeless, returned to
shelters or euthanized in severe forms of stereotypes and exacerbation of chronic diseases. Therefore, it is
extremely important that veterinarians know how to help owners cope with a particular behavioral problem of
an animal, know the reasons leading to various behavioral deviations, forms of disorders and methods for their
diagnosis and treatment. The use of environmental improvement means in general treatment regimen, as an
additional method, improves the quality of life of animals kept in a crowded space and reduces the risk of
exacerbations of chronic diseases. The studies were carried out on the basis of the AmurVet Veterinary Clinic,
Blagoveshchensk, Amur Region. Animals showing clinical signs of behavioral abnormalities (idiopathic cystitis, aggression, dejection, stereotypy, etc.) against the background of triggers were divided into groups. In
each group, the clinical status was monitored and the owners were carefully questioned to identify triggers in
the animal habitat. On the basis of a questionnaire, the methods of improvement of the environment (habitat)were individually selected in each case, and the animals were also prescribed drug therapy to relieve acute
symptoms. As a result, in the group where along with drug therapy, elements of improvement of the environment were used, there was a decrease in the incidence of relapses by 89 %.

The purpose of the experiment is a comparative assessment of rations to determine their influence
on growth indicators and biochemical status of cattle. The research was carried out with the help of the analogpairs method. 24 head of Holstein cattle were selected, which were divided into 3 groups of 8 head each. All
animals received diets with different energy levels: the first group (low energy group), the second group (medium energy group), and third group (high energy group). The observation period for the animals was 100
days, of which the period before feeding was 10 days, 38 days at the early stage and 52 days at the later stage.
The research was carried out at the Harbin North-East Agricultural University Faculty of Veterinary Medicine,
Heilongjiang Province. The crude protein content in the diets of the three groups of animals in the early period
was 12,50%, and the total net energy was 6,80, 7,00 and 7,20 MJ/kg, respectively. The crude protein content
in the late period was 12,00%, and the total net energy was 6,90, 7,10 and 7,30 MJ/kg, respectively. The results
showed that the average daily weight gain in the first group was higher than in the second – 4,76% (p>0.05)
and the third group – 43,48% (p<0,05). The average dry matter consumption was the highest in group II, and
the material-to-weight ratio was the lowest, and the difference between the third group and others was significant (p<0,01). Increasing dietary energy levels can increase serum glucose and cholesterol (p<0,05) and significantly reduce β-hydroxybutyrate (p<0,01). It is worth noting that serum hormone levels increased as energy levels (p>0,05) rose. Thus, raising dietary energy levels can significantly increase average daily weight gain
and reduce feed-to-weight ratio in Holstein cattle.

The research paper presents a comparative analysis of helminth fauna of American mink on the
urbanized territories and natural biocenosis of the Kirov Region (floodplains of the Vyatka, Kama, Cheptsa
and Moloma Rivers) in the north-east of the European part of Russia. The method of complete helminthological dissections was used to study 109 carcasses of American minks, including 70 minks of natural biocenoses
and 39 urbanized landscapes of Kirov and other settlements of the Kirov Region. The extensiveness of the
invasion and the intensity of the invasion were determined. The Student's criterion (t) was used to calculate
the validity of differences at the significance level of 0.05. 18 species of helminths were revealed, of which
five new species for the region including: Metorchis bilis, Crenosoma taiga, Mustelivingylus skrjabini. The
basis of helminth fauna is biohelminths (87.5%). Rate of infection with helminths during the acclimatization
period increased from 9.8 to 92.7%. Helminthofauna is represented by 7 species in urban areas. The dominant
species are 5 helminths: Isthmiophora melis, Alaria alata, larvae, Aonchotheca putorii, Aonchotheca mucronata, Skrjabingylus nasicola. Females of natural biocenoses, as well as urbacenoses, are not infested with
pulmonary helminths C. taiga and Trichinella spp. larvae. The extensiveness of infestation and the intensity
of infestation in the American mink differ slightly from one habitat to another. The intensity of infestation of
A. mucronata is higher in female mink living on the urbanized territories as compared to natural biocenosis.
This difference has statistical significance (t=4.67, p ≤ 0.05). In settlements the intensity of infestation in males
of I. melis and A. putorii exceeds significantly that of females (t=2.1-2.24 with a significance level of p ≤ 0.05).
Epizootological and epidemiological hazards are represented by A. alata (larvae), Metorchis bilis and Trichinella spp.

This study examines Islamic dealings with Christians, Jews, and other religions during the time of the Umayyad Caliphate in Andalus. It aims to highlight Islamic coexistence with the people of the Dhimmah and to clarify openness with various peoples, races, and religious, sectarian, and sectarian affiliations. While achieving these two goals, it is evident that this study refutes the violation of human rights in Andalusia. The researchers used narrative, critical, and analytical approaches. To clarify historical facts and events, the results of this historical study demonstrate the interconnection between the inhabitants of Andalusia, provided practical professions and industries. for various segments of society, resulting in improving their social conditions. The findings further show that it encourages material gain, and the spread of the culture of social justice and freedom, and the era of the nobility as well as the different classes ended. Therefore, people became equal, and Muslims worked to eliminate the sources of corruption and deviant morals, such as sex, immorality, indulging in pleasures, cheating, lying, usury, alcohol, and sodomy. Hence, this coexistence contributed to bringing together the elements of civilization: energy, strength, space, and time. It also provided will and optimism, and these foundations raised Andalusian society better. Muslims provided the people of the Dhimmah with everything they needed and made them participate in shaping the features of Islamic civilization on the European continent.
