QSPR analysis of heart attack medications, especially antiplatelet agents and dual antiplatelet therapy (DAPT), through graph labeling based topological indicators and regression models
Authors: S NANDISH N , P USHA , S RAMANANDA H
Published: March 2024

To model and characterize the molecular structure of pharmaceuticals and forecast their physicochemical properties without undergoing time-consuming and arduous laboratory procedures, labeled-based topological indices are highly helpful tools. Using the concepts of graph theory, these indices are numerical descriptors for the molecular structures. Labeled-based topological indices, which offer molecular descriptors to anticipate the features of pharmaceuticals, are essential for the QSPR analysis of heart attack medications, especially antiplatelet agents and dual antiplatelet therapy (DAPT). This research aims to calculate a linear regression model and eight labeled-based topological indices for five antiplatelet agents and dual antiplatelet therapy (DAPT) medications. These drugs are aspirin, clopidogrel, dipyridamole, prasugrel, and ticagrelor. Linear regression analysis and labeled-based topological indices correlate with various physicochemical properties related to drug activities, such as molar refractivity, polar surface, polarizability, molar volume, surface tension, log P, boiling point, and flash point. By shedding light on how the molecular structure affects these characteristics, correlations aid in the development and improvement of novel pharmaceuticals. In this paper, various statistical parameters are used to analyze antiplatelet agents and dual antiplatelet therapy (DAPT) in the case of a heart attack.

Published: March 2024

This study compares base, hybrid, and voting modeling techniques to predict blast toe volume size. The investigation integrates independent models, explores synergies in hybrid approaches, and optimizes accuracy through ensemble voting to offer comprehensive knowledge and more reliable forecasts for blast toe volume estimation in various design. 457 blasting was investigated and data was collected at Anguran lead and zinc mine in Iran. Nine model accuracy indices were used to compare the algorithm's prediction accuracy. The study indicates a significant relationship between toe volume size and explosive charge per delay, as demonstrated by multicollinearity, Spearman, and Kendall correlation analyses. The analysis of the model showed that Light Gradient Boosting Machine (LightGBM) achieved the highest accuracy compared to the other 8 conventional models, with correlation coefficients (R2) of 0.9004 and 0.8625 for the training and testing datasets, respectively. The Hybrid 6 model, which combines LightGBM and CART algorithms, achieved the highest R2 scores of 0.9473 in the training phase and 0.9467 in the testing phase. The Voting 8 model, consisting of LightGBM, GBM, DT, ET, RF, CatBoost, CART, AdaBoost, and XGBoost, had the greatest R2 scores of 0.9876 and 0.97265 in both the training and testing stages. The voting models can reliably forecast toe volume resulting from a blast design pattern, thereby providing a novel tool for simulation.
Bayesian Hierarchical Network Autocorrelation Models for Estimating Direct and Indirect Effects of Peer Hospitals on Outcomes of Hospitalized Patients
Authors: Chen Guanqing , O'Malley A James
Published: March 2024

When an hypothesized peer effect (also termed social influence or contagion) is believed to act between units (e.g., hospitals) above the level at which data is observed (e.g., patients), a network autocorrelation model may be embedded within a hierarchical data structure thereby formulating the peer effect as a dependency between latent variables. In such a situation, a patient's own hospital can be thought of as a mediator between the effects of peer hospitals and their outcome. However, as in mediation analyses, there may be interest in allowing the effects of peer units to directly impact patients of other units. To accommodate these possibilities, we develop two hierarchical network autocorrelation models that allow for direct and indirect peer effect pathways between hospitals when modeling individual outcomes of the patients cared for at the hospitals. A Bayesian approach is used for model estimation while a simulation study is used to assess the performance of the models and sensitivity of results to different prior distributions. We construct a United States New England region patient-sharing hospital network and apply our Bayesian hierarchical models to study the diffusion of robotic surgery and hospital peer effects in patient outcomes using a cohort of United States Medicare beneficiaries in 2016 and 2017. The comparative fit of models to the data is assessed using Deviance information criteria tailored to hierarchical models that include peer effects as latent variables.
Application of Physics-Informed Neural Networks for Simulating Mass-Spring-Damper Systems
Authors: Sahoo Arup Kumar , Kumar Sandeep , Chakraverty S.
Published: March 2024

Dynamical problems are generally governed by a set of linear/non-linear differential equations (DEs). A large amount of prior physical information in the form of DEs plays an important role in simulation of dynamical systems. However, the traditional data-hungry machine learning models fail to express insightful scientific information from the data. Most of the implementations of neural networks are to perform non-linear mapping from input space to target space. However, Physics-informed neural networks (PINNs) can bridge the gap between scientific computing and data-hungry models. This paper exploits a new application of PINNs for approximating the behaviour of mass-spring-damper systems, showcasing how PINNs can effectively blend scientific principles with data-driven modeling. In this regard, we present solutions of two realistic application problems using PINNs. The accuracy of the predicted displacements of objects is established through results from literatures.
A New Index for Assessing Quality of Solar X-ray Imaging System and Image Reconstruction
Authors: Li Zhentong , Yu Wenhui , Su Yang , Chen Wei , Gan Weiqun
Published: March 2024

Indirect X-ray modulation imaging has been adopted in a number of solar missions and provided reconstructed X-ray images of solar flares that are of great scientific importance. However, the assessment of the image quality of the reconstruction is still difficult which is particularly useful for scheme design of X-ray imaging systems, improvement and testing of imaging algorithms, and scientific research. Currently, there is no specified method to quantitatively evaluate the quality of X-ray images. In this paper, we first propose percentage proximity degree (PPD) by considering the imaging characteristics of X-ray sources and in particular, side lobes and their effects on imaging quality. After screening a variety of imaging quality assessments through systematic testing of six aspects, we utilized the technique for order preference by similarity to ideal solution to the indices that meet the requirements. The final quality index established for X-ray image reconstruction (QuIX), consists of the selected indices and the new PPD, performs well on all the aspects, including assessment of PSF (point spread function) of ASO-S/HXI and simulation tests under different grid configurations, and imaging tests with RHESSI data. It was also found to be a useful tool in determination of proper imaging algorithm and field of view (FOV) for image reconstruction.
Histological identification of physiological changes in vascular cells morphology in the crown of winter barley (Hordeum vulgare L.) during freezing
Authors: Mishra Gayatri
Published: March 2024

Freezing resistant organs in cereal crops can withstand and recover from injuries caused by freezing stresses. To understand the physiological mechanisms of freezing stress survival in winter cereals, a histological analysis of crown was performed on winter barley, that had been frozen and recovered. Freezing injuries in all four zones of the crown were classified as voids and tissue separation caused by ice formation, vessels partially or completely plugged with unknown darkly stained substances. An irregular semi-circular purple zone was recognized in lower crown, zone 1. Tissue necrosis was observed in the innermost leaves in the apical regions of the crown, zone 3 and 4. Different types of cell wall explosions in vessels were characterized in zone 3 and 4. Bordered pits appeared as smaller cell walls within xylem vessels in all the crown zones which may have prevented propagation of ice in the vessels. The study showed that freezing began at the basal region and spread upwards towards the apical region of crown. The results suggest that conventional microscopy can be used for characterizing physiological changes in cereal crops recovering from freezing.
Methylation of the CpG at -299 bp from transcription start site of interleukin-1β is a sustained marker of inflammation exerted by TNFa on bone marrow-derived mesenchymal cells of healthy humans
Authors: Vladimirovich Karpenko Dmitriy
Published: March 2024

Background
The role of bone marrow mesenchymal cells is demonstrated both in normal conditions and in various pathologies of the hematopoietic system. The regulatory functions of mesenchymal cells are so significant that they themselves and their secretome or extracellular vesicles are used for the treatment and prevention of immune complications during transplantation and in other aspects of regenerative medicine. As shown earlier, interleukin-1β (IL1B) is an important factor regulating the activity of the bone marrow stroma.
Methods
Methylation profile of IL1B promoter and IL1B expression were measured in cultured mesenchymal cells obtained from the bone marrow of healthy donors. IL1B expression was also measured upon different inflammatory stimuli including tumor necrosis factor-α (TNF).
Results
For healthy donor mesenchymal cells, we observed differences in IL1Bpromoter methylation profile at the position of one CpG at -299 bp from transcription start site, which is a part of or in immediate proximity to binding sites of NF-kB transcription factors. The study establishes a link among TNF exposure, the CpG methylation, and IL1B expression during and after exposure.
Conclusion
Since TNF is a pro-inflammatory factor that is associated with damage and aging, it is concluded that for healthy donor mesenchymal cells, the observed differences in IL1B promoter methylation profile may be a long-term imprint of inflammatory processes previously sustained by a person, as well as a marker of physiological differences in the human bone marrow stroma.
Species Distribution Model for the Asian Tapir and Vegetation Characteristics of Batang Gadis National Park, North Sumatra, Indonesia
Authors: Wanda Kuswanda  , Freddy Jontara Hutapea  , Muhammad Hadi Saputra  , Bobby Nopandry
Published: March 2024

The Asian tapir is a primitive mammal whose habitat is heavily fragmented due to human activities. Studies on the Asian tapirs in Sumatra are very few, thereby basic information for developing tapir conservation programmes is limited. This study aimed to develop the species distribution model to map the potential distribution of tapirs in Batang Gadis National Park (BGNP), investigate the characteristic of tapir habitat, and identify tapir feed plants around BGNP. The model was developed using the Maximum Entropy (Maxent) approach, based on the existing information on tapir occurrence in BGNP and environmental variables. Vegetation characteristics in different land cover (primary forests, secondary forests, and open fields) were investigated using the strip transect method. This study found that zonal classification, temperature and precipitation have the greatest percentage contribution to the model. The model estimated that around 24.45% of BGNP areas are suitable for tapir habitat, and tapirs distribute near community gardens. Our results also showed that plant diversity at study sites was categorised as moderate-high. About 23 plant species dominated by the Moraceae family were identified as feed plants for tapirs. In developing tapir conservation programmes, BGNP management needs to consider tapir distribution that is closed to community gardens. We propose BGNP to enrich feed plants in open fields of the wilderness and traditional zones; reduce the canopy cover in the wilderness and utilisation zones to stimulate the growth of feed plants; facilitate local people to live harmoniously with tapirs; involve local communities in tapir conservation programmes; encourage local communities to plant non-palatable crops for tapirs; and provide a compensation scheme.
Crystallographic insights into monovalent thallium incorporation: Exploring hydropyrochlore structure for environmental remediation
Authors: Taddei Alice , Bindi Luca , Lepore Giovanni O. , Skogby Henrik , Bonazzi Paola
Published: March 2024

Hydropyrochlore, ideally (H2O,☐)2Nb2(O,OH)6(H2O), is a cubic mineral (space group Fd3m, a = 10.56–10.59 Å, Z = 8) belonging to the pyrochlore supergroup (general formula: A2–mB2X6–wY1–n). The K-rich variety of this species is unique to the Lueshe syenitic-carbonatitic deposit (D.R. Congo), where it occurs as the alteration product of primary (Ca,Na)2Nb2O6F pyrochlores. The structure of this mineral is made of a B2X6 (B = Nb, Ti; X = O, OH) framework that generates tunnels along the [110] direction, where the interstitial sites are partially occupied by water molecules and minor amounts of different cations. These features form the basis for the ion-exchange properties of hydropyrochlore, making it a promising candidate as a mineral sink for heavy metals (e.g., Tl+) dispersed in aqueous matrices, with interesting environmental implications.

Tl+ incorporation was induced through imbibition experiments in a diluted Clerici solution using single crystals of hydropyrochlore from Lueshe (D.R. Congo); the modifications induced by Tl+ incorporation were then evaluated using single-crystal X-ray diffraction (SCXRD), electron microprobe analyses (EMPA), and Fourier transform infrared (FTIR) spectroscopy.

After Tl+ imbibition, a dramatic increase of the A-site electron density (n.e– from ~4 to ~60) confirms the entry of a substantial amount of Tl+ at this site (up to about 70%), leading to a lengthening of the A-X distances and the consequent expansion of the unit cell. A decrease of the site scattering at the Y′ site (from ~9 to ~4 e–) also occurs, suggesting a loss of aqueous species. Although the predominance of neutral H2O molecules at the interstitial sites of hydropyrochlore from Lueshe is widely accepted by the mineralogical community, our crystal-chemical and FTIR data provide evidence that the dominant species might be the hydronium ion, with significant implications on the nomenclature of the pyrochlore supergroup.

Understanding the crystallographic aspects of hydropyrochlore as a potential waste form for monovalent thallium immobilization not only addresses a pressing environmental concern but also contributes to the broader field of waste management.

Menstrual Hygiene Management (MHM) is essential for women's health, but it is often regarded as a taboo topic. This study investigates the practice of MHM in rural and remote Indonesian highlands. A cross-sectional study was conducted among 492 adolescent girls and adult women in the Jayawijaya and Central Mamberamo Districts of Papua Province. Principal component analysis and multiple regression analyses were used to examine the relationships among the respondents' knowledge, attitudes, and MHM practices. The perception that discussing MHM is taboo exists in this area, and certain cultural rituals are associated with a young girl's first period. The respondents have moderate knowledge and attitudes regarding MHM. Furthermore, their practices after using sanitary pads are unhygienic, may increase the risk of reproductive tract infections, and may pollute the environment. Some variables are positively associated with appropriate MHM practice, namely knowledge of MHM, the perception that menstruation must be kept private, and the importance of using sanitary pads. Finally, the results show that schools do not provide a supportive environment for girls during their period. Overall, there is a need to increase MHM knowledge and foster positive attitudes to enhance healthy MHM among women in the rural and remote highlands of Indonesia.

A energia solar tende a disseminar-se amplamente na utilização cotidiana para suprir a crescente demanda energética, esta possui uma gama de benefícios e vantagens na sua implementação, principalmente pelo caráter pouco poluente ao meio ambiente. Os painéis fotovoltaicos somente atingiram os patamares atuais de geração graças ao desenvolvimento da eletrônica de potência, que é utilizada no processamento da energia fotogerada, porém a eficiência ainda é em torno de 20%, ao mesmo tempo que os parâmetros elétricos dos módulos são diretamente influenciados por fatores climáticos e ambientais, tornando seu controle complexo. Para isso, técnicas vêm sendo criadas de forma a manter os sistemas fotovoltaicos operando com sua eficiência máxima independente dos fatores. Tais técnicas são denominadas de rastreamento do ponto de máxima potência (MPPT – Maximum Power Point Tracking), no qual se utilizam conversores controlados por algoritmos que rastreia o ponto de máxima potência (PMP), e assim mantém os painéis solares entregando sua potência útil máxima. Existem na literatura diversas técnicas de controle MPPT, a abordada no presente trabalho será uma denominada Hill CLimbing. Desenvolveu-se em software Matlab/Simulink a modelagem de um sistema de controle MPPT utilizando como conversor o tipo buck-boost controlado pelo algoritmo Hill Climbing. Após a modelagem foi analisado o funcionamento do algoritmo através do rastreamento do PMP e comparado com os valores obtidos experimentalmente do módulo ZW85X115. O comparativo entre os valores experimentais e simulados ocorreu de forma satisfatória.

Comparison of Carbon Footprint, Environment Impact, Efficacy and Benefit–Cost Ratio of Insecticide Resistance Management with Conventional Methods used by Thai Chinese Cabbage Farmers
Authors: Sampaothong Sonthaya , Punyawattoe Pruetthichat
Published: March 2024

Aim

To evaluate and compare the carbon footprint, efficacy, and benefit-cost ratios of Chinese cabbage grown via insecticide resistance management with two farming methods used by Thai farmers.

Background

Insecticide usage is currently being reduced by the employment of sustainable products and the promotion of environmentally friendly methods, thereby increasing the income of Chinese cabbage farmers in Thailand.

Methods

This study aims to evaluate the control of insect pests and marketable produce in Chinese cabbage using various methods. Pests were counted every five days, and the marketable produce was evaluated. Greenhouse gas emissions and environmental impact were estimated using methodologies such as the environmental impact quotient, with the pesticide usage costs and benefit-cost ratios recorded.

Results

The study compared two farming methods with insecticide resistance management, revealing that in the growing of Chinese cabbage, the latter exhibited lower emissions per acre and kg. However, the environmental impact was higher in methods 1 and 2 due to the increased spray application involved. The insecticide resistance management method was found to effectively control pests and produce marketable produce with less total investment and labour expenses.

Conclusion

The study analysed the impact of farming practices and pesticide resistance management strategies on the environment and carbon emissions. The results showed that insecticide resistance management is more effective in reducing carbon emissions and positively impacting the environment while also providing a better benefit-cost ratio. However, the study suggests that education and continuous monitoring are required for effective resistance management. The findings also emphasise the need for adaptation to changing pests and the consideration of external factors such as market demand, climate change, and government policies to ensure long-term sustainability.

Published: March 2024

In many nations, motorcycle accidents are a big public issue. Despite public
awareness campaigns, the problem continues to grow as a result of poor riding habits
such as riding without a helmet, dangerous driving, drunk driving, riding without
enough sleep, and so on. Because of late help to those who have been in accidents, the
rate of deaths and disabilities is quite high. People who are implicated suffer significant
economic and social consequences as a result of them. As a result, various research
organizations and large motorcycle companies have developed safety systems to
safeguard riders from harm. Furthermore, a dElectronics and Communication
Engineeringnt motorcycle safety system is hard to execute and costly. The integration
of modern communication technologies into the automotive industry allows for greater
assistance to people wounded in traffic accidents, a reduction in the time it takes
emergency services to respond, and an increase in the amount of knowledge they have
about the occurrence. The number of fatalities might be greatly reduced if the resources
necessary for each disaster could be determined more precisely. The developed scheme
calls for every vehicle to be equipped with an on-board unit that detects and reports
accident scenarios to an exterior control unit that assesses the depth of the problem and
provides the needed resources to aid it. The creation of a prototype based on off-th-
-shelf equipment indicates that this technology can considerably reduce the time it
takes to send emergency services following an accident.

One of the key predictions that had combined bio-sciences with innovation
was bio-metrics, which represents a tool for security and criminology analysts to
develop more accurate, robust, and certain frameworks. Biometrics, when combined
with different combination techniques like feature-level, score-level, and choice-level
combination procedures, remained one of the most researched technologies. Starting
from uni-modular biometrics as unique marks, faces, and iris, they progress to
multimodal bio-metrics. By presenting a similar investigation of frequently used and
referred to uni- and multimodal biometrics, such as face, iris, finger vein, face and iris
multimodal, face, unique mark, and finger vein multimodal, this paper will attempt to
lay the groundwork for analysts interested in enhanced biometric frameworks. This
comparative research includes the development of a comparison model based on DWT
and IDWT. The method towards combining the modalities also entails applying a
single-level, two-dimensional wavelet (DWT) that has been cemented using a Haar
wavelet to accomplish the best pre-taking care of to eliminate disturbance. Each pixel
in the picture is subjected to a different filtering operation in order to determine the
peak signal to noise extent (PSNR). This PSNR analyses the mean square error (MSE)
to quantify the disruption to hail before playing out the division of the largest dataset to
the chosen MSE. In the most recent advancement, each pixel's concept is fixed up
using the opposing two-dimensional Haar wavelet (IDWT), creating a longer image
that is better able to recognise approbation, affirmation, and confirmation of parts. The
MATLAB GUI is used to implement the diversions for this enhanced blend
investigation, and the obtained outcomes are satisfactory.

putting us in the dark if attacked. Many works of literature have recently attempted to
address the issues surrounding IoT security, but few of them tackle the serious dangers
that the development of quantum computing poses to IoT. Lattice-based encryption, a
likely contender for the next post-quantum cryptography standard, benefits from strong
security guarantees and great efficiency, making it well-suited for IoT applications. In
this article, we list the benefits of lattice-based cryptography and the most recent
developments in IoT device implementations.

The Internet of Things (IOT) is a new technology that is anticipated to improve human
