Published: July 2023

From the Islamic economic perspective, there are factors that can influence economic growth, namely the distribution of ZIS funds. The distribution of ZIS funds can be used to encourage economic growth in a positive direction. This study aimed to examine how the direction of the relationship between consumption, government expenditure, and distribution of ZIS funds has on Indonesia's economic growth. The method used is a quantitative approach, using Granger causality data analysis techniques and cointegration tests. The data used is secondary data from the Central Bureau of Statistics with the type of time series data. This study shows that there is a two-way causality between household consumption and Indonesia's economic growth. There is a one-way causality between government expenditure and Indonesia's economic growth, where Economic growth affects government expenditure and not vice versa. There is a one-way causality between the distribution of ZIS funds to Indonesia's economic growth, where the distribution of ZIS funds affects economic growth and not vice versa.

A Novel Approach to Cervical Cancer Detection Using Hybrid Stacked Ensemble Models and Feature Selection
Authors: Nandanwar Pratiksha D. , Dhonde Dr. Somnath B.
Published: July 2023

Around the world, millions of women are diagnosed with cervical cancer each year. Early detection is very important to produce a better overall quality of life for those diagnosed with the disease and reduce the burden on the healthcare system. In recent years, the field of machine learning (ML) has been developing methods that can improve the accuracy of detecting cervical cancer. This paper presents a new approach to this problem by using a combination of image segmentation and feature extraction techniques. The proposed approach is divided into three phases. The first stage involves image segmentation, which is performed to extract the regions of interest from the input image. The second stage is comprised of extracting the features from the ROI with the help of the Histogram and Hu Moments techniques. The techniques used in this approach, namely the Hu Moments and Histogram techniques, respectively, can capture the shape information in the ROI. In the third stage of the project, we use a hybrid approach to classify the image. The proposed model is composed of several base classifiers, which are trained on varying subsets of the features that were extracted. These resulting classifiers then make a classification decision. We tested the proposed model against a large dataset of images for cervical cancer. The results of the experiments revealed that it performed better than the existing methods in detecting the disease. It was able to achieve an accuracy of 96.5%, an F1 score of 96.9%, and a recall of 96.7%. The proposed model was successful in accomplishing a remarkable accuracy of 96.5%, making it an ideal candidate for use in the detection of cervical cancer. It was also able to perform feature extraction using the Histogram techniques and image segmentation. The proposed method could help medical professionals improve the diagnosis and reduce the burden of this disease on women worldwide.

Published: July 2023

Machine learning is commonly utilised to construct an intrusion detection system (IDS) that automatically detects and classifies network intrusions and host-level threats. Malicious assaults change and occur in high numbers, needing a scalable solution. Cyber security researchers may use public malware databases for research and related work. No research has examined machine learning algorithm performance on publicly accessible datasets. Data and physical level security and analysis for Data protection have become more important as data volumes grow. IDSs collect and analyse data to identify system or network intrusions for data prevention. The amount, diversity, and speed of network data make data analysis to identify assaults challenging. IDS uses machine learning methods for precise and efficient development of data security mechanism. This work presented intrusion detection model using machine learning, which utilised feature extraction, feature selection and feature modelling for intrusion detection classifier.
Implementation of an Exponential Mathematical Model of Power-Torque Curves in an Algorithm for Natural Aspirated and Turbocharged Internal Combustion Engines
Authors: Di Rado Gustavo Ruben , García Daniel Sergio Presta
Published: July 2023

Overtaking is one of the most complex maneuvers performed on two-lane rural highways, and its associated accidents account for a large proportion of the mortality connected to traffic accidents. In addition, the number of long vehicles, such as trucks or buses, using these traffic routes is increasing significantly. On the other hand, to perform this maneuver characterized by a fast and a slow vehicle, the engine of the fast one must have sufficient elasticity to achieve the required acceleration in the high gears, and in this sense, the turbo engine can provide this performance, with small engines and fuel savings. In this work, we develop an algorithm to simulate both naturally aspirated and turbocharged engines, fitting their characteristics based on an exponential model and comparing them with those on test benches.
Predicting the Crystal Structure of Beryl from the Chemical Composition
Authors: Henry Rhiana E. , Groat Lee A. , Cempírek Jan , Škoda Radek , Holá Markéta
Published: July 2023

Crystal-structure prediction is a challenging topic. Few models have been developed that use the chemical composition of a known compound to determine a complete crystal structure. A complete structural model should include all major bond lengths and angles, atomic coordinates, polyhedral volumes and distortions, and unit-cell parameters. The mineral beryl is used here to develop such a model.

Beryl (Be3Al2Si6O18) is an ideal mineral to show that predicting the crystal structure using chemistry is possible: the framework structure is known, this structure has only two cation sites that experience substitutions, and these substitutions only minimally occur simultaneously. Vacant channel sites are involved in coupled substitutions, allowing alkali cations (typically Na+) to enter the structure, and the channel regularly contains molecular H2O correlated to Na content (Henry et al. 2022). The research employed single-crystal X-ray diffraction and electron probe microanalyses of 80 samples to create a model which was subsequently tested using 33 samples.

Results show that the complete crystal structure of beryl can be accurately calculated using the Al-site average ionic radius (Al-SAIR) for octahedrally trending beryl, or the Be-site average ionic radius (Be-SAIR) for tetrahedrally trending beryl. Beryl for which Al-SAIR > (0.45 × Be-SAIR) + 0.414 is considered octahedrally trending and that for which Al-SAIR ≤ (0.45 × Be-SAIR) + 0.414 is considered tetrahedrally trending. Red beryl (differentiated by high Fe and Mn) exhibits a different trend, forming a subset of the octahedrally trending beryl. There is an upper limit to the predictable range of beryl structures of 0.604 Å Al-SAIR or 0.326 Å Be-SAIR. This model makes it possible to explore limitations on the crystal structure of beryl and the potential for unusual cation substitutions, or conversely, to compute the structure of a hypothetical pure endmember beryl. It is robust for true beryl (beryl for which Be and Al are the dominant non-Si cations) up to a high limit of cation substitutions, but not for other beryl-group minerals, including stoppaniite, bazzite, avdeevite, and johnkoivulaite.

Future studies on beryl will be able to estimate basic crystal-structure features arising from standard chemical analyses as used in this research. It enables the creation of an extensive beryl database, aids comparisons of natural beryl to synthetics, and helps provide further guidance on provenance studies. It also invites future crystal-structure prediction research. This approach is applicable to broader fields, as crystal structures are linked to the physical characteristics of minerals and rocks in which they form.

Generation of shortest path search dataflow networks of actors for parallel multi-core implementation
Authors: Prihozhy A. A.
Published: July 2023

Objectives. The problem of parallelizing computations on multicore systems is considered. On the Floyd – Warshall blocked algorithm of shortest paths search in dense graphs of large size, two types of parallelism are compared: fork-join and network dataflow. Using the CAL programming language, a method of developing actors and an algorithm of generating parallel dataflow networks are proposed. The objective is to improve performance of parallel implementations of algorithms which have the property of partial order of computations on multicore processors.Methods. Methods of graph theory, algorithm theory, parallelization theory and formal language theory are used.Results. Claims about the possibility of reordering calculations in the blocked Floyd – Warshall algorithm are proved, which make it possible to achieve a greater load of cores during algorithm execution. Based on the claims, a method of constructing actors in the CAL language is developed and an algorithm for automatic generation of dataflow CAL networks for various configurations of block matrices describing the lengths of the shortest paths is proposed. It is proved that the networks have the properties of rate consistency, boundedness, and liveness. In actors running in parallel, the order of execution of actions with asynchronous behavior can change dynamically, resulting in efficient use of caches and increased core load. To implement the new features of actors, networks and the method of their generation, a tunable multi-threaded CAL engine has been developed that implements a static dataflow model of computation with bounded sizes of buffers. From the experimental results obtained on four types of multi-core processors it follows that there is an optimal size of the network matrix of actors for which the performance is maximum, and the size depends on the number of cores and the size of graph.Conclusion. It has been shown that dataflow networks of actors are an effective means to parallelize computationally intensive algorithms that describe a partial order of computations over decomposed data. The results obtained on the blocked algorithm of shortest paths search prove that the parallelism of dataflow networks gives higher performance of software implementations on multicore processors in comparison with the fork-join parallelism of OpenMP.

Published: July 2023

The current study investigates how interpersonal trust between the auditor and the client firms’ managers affects the auditor's professional skepticism in Iraq. In the qualitative part of the research, 20 auditors and client firms’ managers were interviewed. In the qualitative section, the interviews conducted were analyzed using MAXQDA software. The statistical population includes two groups: all auditors, 1735 participants until the end of 2022, and all senior managers and managers of public companies, private companies, and other organizations. The statistical sample size is 314. The data collection instrument was Aschauer et al.'s (2017) questionnaire, which was analyzed using PLS3 software. The findings support the idea that there is a positive correlation between the degree of skepticism towards the auditing profession and the degree to which corporate managers and auditors are trusted. Perceived trust between auditors and managers and skepticism of auditors' professions are not significantly correlated with the length of the auditor's contact with the client. The relationship between auditors' and managers' trust in them and their skepticism of the auditing profession is not also significantly impacted by the supply of non-audit services.

We combine James Webb Space Telescope (JWST) and Hubble Space Telescope imaging with Atacama Large Millimeter Array CO(2–1) spectroscopy to study the highly turbulent multiphase intergalactic medium (IGM) in Stephan’s Quintet on 25–150 pc scales. Previous Spitzer observations revealed luminous H2 line cooling across a 45 kpc-long filament, created by a giant shock wave, following the collision with an intruder galaxy, NGC 7318b. We demonstrate that the Mid-Infrared Instrument/F1000W/F770W filters are dominated by 0–0 S(3) H2 and a combination of polycyclic aromatic hydrocarbon and 0–0 S(5) H2 emission. These observations reveal the dissipation of kinetic energy as massive clouds experience collisions, interactions, and likely destruction/recycling within different phases of the IGM. In 1 kpc-scaled structure, warm H2 was seen to form a triangular-shaped head and tail of compressed and stripped gas behind a narrow shell of cold H2. In another region, two cold molecular clumps with very different velocities are connected by an arrow-shaped stream of warm, probably shocked, H2 suggesting a cloud–cloud collision is occurring. In both regions, a high warm-to-cold molecular gas fraction indicates that the cold clouds are being disrupted and converted into warm gas. We also map gas associated with an apparently forming dwarf galaxy. We suggest that the primary mechanism for exciting strong mid-IR H2 lines throughout Stephan’s Quintet is through a fog of warm gas created by the shattering of denser cold molecular clouds and mixing/recycling in the post-shocked gas. A full picture of the diverse kinematics and excitation of the warm H2 will require future JWST mid-IR spectroscopy. The current observations reveal the rich variety of ways that different gas phases can interact with one another.

We present kinematics of six local extremely metal-poor galaxies (EMPGs) with low metallicities (0.016–0.098 Z
⊙) and low stellar masses (104.7–107.6
M
⊙). Taking deep medium/high-resolution (R ∼ 7500) integral-field spectra with 8.2 m Subaru, we resolve the small inner velocity gradients and dispersions of the EMPGs with Hα emission. Carefully masking out substructures originating by inflow and/or outflow, we fit three-dimensional disk models to the observed Hα flux, velocity, and velocity dispersion maps. All the EMPGs show rotational velocities (v
rot) of 5–23 km s−1 smaller than the velocity dispersions (σ
0) of 17–31 km s−1, indicating dispersion-dominated (v
rot/σ
0 = 0.29–0.80 < 1) systems affected by inflow and/or outflow. Except for two EMPGs with large uncertainties, we find that the EMPGs have very large gas-mass fractions of f
gas ≃ 0.9–1.0. Comparing our results with other Hα kinematics studies, we find that v
rot/σ
0 decreases and f
gas increases with decreasing metallicity, decreasing stellar mass, and increasing specific star formation rate. We also find that simulated high-z (z ∼ 7) forming galaxies have gas fractions and dynamics similar to the observed EMPGs. Our EMPG observations and the simulations suggest that primordial galaxies are gas-rich dispersion-dominated systems, which would be identified by the forthcoming James Webb Space Telescope observations at z ∼ 7.

Published: July 2023

We present a new methodology for simulating mid-infrared emission from polycyclic aromatic hydrocarbons (PAHs) in galaxy evolution simulations. To do this, we combine theoretical models of PAH emission features as they respond to varying interstellar radiation fields, grain-size distributions, and ionization states with a new model for dust evolution in galaxy simulations. We apply these models to three idealized arepo galaxy evolution simulations within the smuggle physics framework. We use these simulations to develop numerical experiments investigating the buildup of PAH masses and luminosities in galaxies in idealized analogs of the Milky Way, a dwarf galaxy, and a starburst disk. Our main results are as follows. Galaxies with high specific star formation rates have increased feedback energy per unit mass, and are able to shatter grains efficiently, driving up the fraction of ultrasmall grains. At the same time, in our model large radiation fields per unit gas density convert aliphatic grains into aromatics. The fraction of dust grains in the form of PAHs (q
PAH) can be understood as a consequence of these processes, and in our model PAHs form primarily from interstellar processing (shattering) of larger grains rather than from the growth of smaller grains. We find that the hardness of the radiation field plays a larger role than variations in the grain-size distribution in setting the total integrated PAH luminosities, though cosmological simulations are necessary to investigate fully the complex interplay of processes that drive PAH band luminosities in galaxies.

We present 850 μm polarization and C18O (3-2) molecular line observations toward the X-shaped nebula in the California molecular cloud using James Clerk Maxwell Telescope (JCMT)’s SCUBA-2/POL-2 and HARP instruments. The 850 μm emission shows that the observed region includes two elongated filamentary structures (Fil1 and Fil2) having chains of regularly spaced cores. We measured the mass per unit length of the filaments and found that Fil1 and Fil2 are thermally super- and subcritical, respectively, but both are subcritical if nonthermal turbulence is considered. The mean projected spacings (

is smaller than 4× the filament width expected in the classical cylinder fragmentation model. The large-scale magnetic field orientations shown by Planck are perpendicular to the long axes of Fil1 and Fil2, while those in the filaments obtained from the high-resolution polarization data of JCMT are disturbed, but those in Fil1 tend to have longitudinal orientations. Using the modified Davis–Chandrasekhar–Fermi method, we estimated the magnetic field strengths (B
pos) of the filaments, which are 110 ± 80 and 90 ± 60 μG, respectively. We calculated the gravitational, kinematic, and magnetic energies of the filaments, and found that the fraction of magnetic energy is larger than 60% in both filaments. We propose that the dominant magnetic energy may lead the filament to be fragmented into aligned cores as suggested by Tang et al., and the shorter core spacing can be due to a projection effect via the inclined geometry of the filaments or due to nonnegligible longitudinal magnetic fields in the case of Fil1.

The presence of strong breaks and the absence of strong emission lines give high confidence that these two galaxies have redshifts z > 9.6, but the redshift values derived from the breaks alone have large uncertainties given the low spectral resolution and relatively low S/N of the CEERS NIRSpec prism data. The two z ∼ 10 sources observed are relatively luminous (M

Considered together with spectroscopic observations of other CEERS NIRCam-selected high-z galaxy candidates in the literature, we find a high rate of redshift confirmation and low rate of confirmed interlopers (8%). Ten out of 35 z > 8 candidates with CEERS NIRSpec spectroscopy do not have secure redshifts, but the absence of emission lines in their spectra is consistent with redshifts z > 9.6. We find that z > 8 photometric redshifts are generally in agreement (within their uncertainties) with the spectroscopic values, but also that the photometric redshifts tend to be slightly overestimated (〈Δz〉 = 0.45 ± 0.11), suggesting that current templates do not fully describe the spectra of very-high-z sources. Overall, the spectroscopy solidifies photometric redshift evidence for a high spatial density of bright galaxies at z > 8 compared to theoretical model predictions, and further disfavors an accelerated decline in the integrated UV luminosity density at z > 8.

Estimations and optimal censoring schemes for the unified progressive hybrid gamma-mixed Rayleigh distribution
Authors: Lone Showkat Ahmad , Panahi Hanieh , Anwar Sadia , Shahab Sana
Published: July 2023

Censoring is a common occurrence in reliability engineering tests. This article considers estimation of the model parameters and the reliability characteristics of the gamma-mixed Rayleigh distribution based on a novel unified progressive hybrid censoring scheme (UPrgHyCS), where experimenters are allowed more flexibility in designing the test and higher efficiency. The maximum likelihood estimates of the model parameters and reliability are provided using the stochastic expectation–maximization algorithm based on the UPrgHyCS. Further, the Bayesian inference associated with any parametric function of the model parameters is considered using the Markov chain Monte Carlo method with the Metropolis-Hastings (M-H) algorithm. Asymptotic confidence and credible intervals of the proposed quantities are also created. The maximum a posteriori estimates of the model parameters are acquired. Due to the importance of determining the optimal censoring scheme for reliability problems, different optimality criteria are proposed and derived to find it. This method can help to design experiments and get more information about unknown parameters for a given sample size. Finally, comprehensive simulation experiments are provided to investigate the performances of the considered estimates, and a real dataset is analyzed to elucidate the practical application and the optimality criterion work in real life scenarios. The Bayes estimates using the M-H technique show the best performance in terms of error values.

Due to the difficulty and high cost of collecting large volumes of data in the maritime industry, in many maritime studies, ML models are trained with small training datasets. The relative predictive performances of these trained ML models are then compared with each other and with the conventional model using the same test set. The ML model that performs the best out of the ML models and better than the conventional model on the test set is regarded as the most effective in terms of this prediction task. However, in scenarios with small datasets, this common process may lead to an unfair comparison between the ML and the conventional model. Therefore, we propose a novel process to fairly compare multiple ML models and the conventional model. We first select the best ML model in terms of predictive performance for the validation set. Then, we combine the training and the validation sets to retrain the best ML model and compare it with the conventional model on the same test set. Based on historical port state control (PSC) inspection data, we examine both the common process and the novel process in terms of their ability to fairly compare ML models and the conventional model. The results show that the novel process is more effective at fairly comparing the ML models with the conventional model on different test sets. Therefore, the novel process enables a fair assessment of ML models' ability to predict key performance indicators in the context of limited data availability in the maritime industry, such as predicting the ship fuel consumption and port traffic volume, thereby enhancing their reliability for real-world applications.

The central tenet in PCOS is predicting the development of the development of metabolic syndrome is Insulin resistance (IR). Adipocytokines are hormones produced by adipose cells that help to regulate insulin secretion and resistance in the body. This study discusses the effect of different adipocytokines and their patterns (increased or reduced) in predicting insulin resistance in obese and lean PCOS patients. A systematic review and meta-analysis were performed which identified relevant studies from 2010 to 2020. Data was analyzed using Review Manager Version (RevMan) 5.4 software. A fixed-effect model was fitted to estimate the pooled effect of adipocytokines. I2 test statistics were done to test the heterogeneity of included studies. Of 17 selected studies with 1504 participants, there is considerably lower levels of adiponectin among women with PCOS as compared with healthy controls with mean difference of −3.79 (95% CI = 3.97–3.60, I2 = 73%; P = 0.005). In comparison to their healthy counterparts, leptin levels were shown to be higher in women with PCOS with mean difference of 3.64 (95% CI = 3.20–4.08, I2 = 97%; P = 0.00001). Leptin concentration was shown to be directly related to IR and BMI. After controlling for BMI and age-related effects, adiponectin levels appear to be lower in women with PCOS compared to non-PCOS controls but leptin levels appear to be higher. In conclusion, increased in adipocytokines such as leptin, visfatin and chemerin predict IR among both obese and lean PCOS whereas decreased levels of zinc-alpha2 glycoprotein predict IR. Adipocytokines can be potential predictive serum biomarkers of insulin resistance (IR) in PCOS.
La Revolución mexicana en el cine documental de la época silente (1910-1917)
Authors: Silva-Escobar Juan Pablo
Published: July 2023

En este trabajo se analizan los documentales del período silente de la Revolución mexicana, específicamente aquellos que fueron realizados durante el fragor de la contienda armada entre 1910 y 1917. El objetivo es reflexionar acerca del modo en que las imágenes fílmicas contribuyeron a forjar el mito de la Revolución como mexicanidad y, a partir de esa mitificación, problematizar la temporalidad de las imágenes y su devenir social y político. Se sostiene que los documentales del período revolucionario favorecieron de manera significativa (junto con otras prácticas culturales: pintura, literatura, teatro) la estructuración de un imaginario social que concibió la lucha armada como seña de identidad. El análisis de los documentales rodados durante el proceso revolucionario mostrará cómo esas imágenes fílmicas hicieron legible una historicidad de la Revolución y, al mismo tiempo, inscribieron una nueva matriz cultural que instituyó, por ejemplo, al campesinado rebelde como discurso sobre el cual construir esa nueva mexicanidad. De este modo, la Revolución como mexicanidad se instauró como un nuevo paradigma sociopolítico sobre el cual se cimentó el nacionalismo populista que se irá conformando como ethos cultural dentro de la sociedad mexicana a lo largo del siglo XX.
Dos fotografías de María Egües Ortiz (1917-2008): una mirada periscópica en tiempos de brumoso silencio
Authors: Barbero Briones Sergio
Published: July 2023

María Egües (1917-2008) fue una investigadora y tecnóloga en el ámbito de los instrumentos ópticos; figura esencial para entender el desarrollo de la ingeniería óptica en las primeras décadas del franquismo. Partiendo de dos fotografías, hasta hace poco inéditas, que reflejan dos momentos cruciales de su vida profesional, este ensayo ofrece una reflexión sobre como una mujer como Egües se vio a sí misma en un tiempo en el que la mera presencia de una mujer en el sistema tecno-científico era, en no pocas ocasiones, rechazada o ignorada. A partir del recurso metafórico de los periscopios submarinos, los cuales permiten ver sin ser vistos, aquella tecnóloga, cual submarino, pudo progresar en unas instituciones, el CSIC, la Universidad y el Ejército, auténticos resortes tecnológicos del Estado franquista, ante miradas hostiles o recelosas. Con todo, aquel régimen, que, parafraseando a Pedro Laín, con su «atroz desmoche», tanto había cercenado al árbol de la ciencia española, no podía permitirse despreciar la participación de algunas mujeres como Egües, imprescindibles en la reconstrucción de un sistema tecno-científico, tan necesario para la supervivencia del propio sistema, a pesar de ciertas retóricas atávicas. Así ocurrió con el desarrollo de una nada desdeñable industria de instrumentos ópticos, en especial, cómo no, aquellos de uso militar. Ámbito en el que María Egües, con forzada discreción y perseverante esfuerzo, alcanzaría uno de los más notables hitos: el diseño y fabricación de los primeros periscópios netamente españoles del siglo XX.
Prácticas de transparencia y reproducibilidad en artículos de revistas españolas de Biblioteconomía y Documentación

Published: July 2023

Introducción y objetivo: La transparencia y reproducibilidad son principios esenciales de la Ciencia Abierta. El objetivo de este estudio fue evaluar la presencia de indicadores de reproducibilidad y transparencia en revistas españolas de Biblioteconomía y Documentación.
Métodos: Se buscó en la base de datos Web of Science los artículos publicados en revistas españolas clasificadas en la categoría Information Science and Library Science en el Journal Citation Reports desde el año 2020 hasta el 1 de marzo de 2022. De la lectura del texto completo de los artículos, se evaluó el acceso abierto, la declaración de fuentes de financiación y conflictos de interés, la disponibilidad de datos, materiales y scripts.
Resultados y conclusiones: Todas las revistas son de acceso abierto, si bien una de ellas requiere pagar por publicar en abierto. Nuestro estudio demuestra que las prácticas relacionadas con la transparencia y reproducibilidad son poco frecuentes. Los investigadores deben poner a disposición del público los datos, materiales y scripts, y ser transparentes sobre las fuentes de financiación y conflictos de interés. Los editores de revistas deben recomendar y animar a los investigadores a cumplir con estas prácticas que podrían ayudar a mejorar la investigación reproducible en la disciplina.

Published: July 2023

Introduction: The adipose tissue in the right ventricle is frequently found during forensic autopsies. However, the pathological significance of right ventricular lipomatosis was not well studied in the available literature. This study aims to study identify the relationship between right ventricular lipomatosis and sociodemographic factors, BMI, and waist circumferenceMethods: Assessment of the fatty infiltration and fibrosis was performed by two pathologists who read all specimens separately. The average of the two values was taken for analysis.Results: A total of 100 decedents were examined in this study, of which 70 were male,76 were Caucasians thirteen were black, nine were Asian, and two were Native American. Among the population 76 were older than 30. Seventy-one out of a hundred recorded a BMI of more than 25, and 63 decedents had a normal waist circumference. Fat infiltration of the anterior wall and lateral wall and average fat infiltration of the right ventricle showed significant association with the female sex and the Caucasian population at a 95% confidence interval. Neither cause of death, past medical history, nor fibrosis of the right ventricle walls showed significant association with the fat infiltration of the right ventricle. Yet, age above 30 years and body mass index over 25 showed a significant association in the fat infiltration of the posterior wall (p-value < 0.05). At the same time, higher waist circumference was significantly associated with the average right ventricular fat infiltration (p-value < 0.05).Conclusion: Right ventricular lipomatosis is significantly associated with BMI and waist circumference in our study. At the same time, it was positively correlated with age, sex, and race.

Cardiovascular morbidity is the leading cause of death worldwide. Physical activity, including aerobic, balance, flexibility, and muscle and bone strengthening, can prevent cardiovascular disease (CVD) at lower cost. Yoga is a natural treatment option that does not involve taking medications or other artificial substances, which may be appealing to some people who prefer to use natural remedies whenever possible. In addition to lowering blood pressure, yoga has many other health benefits, such as improving flexibility, strength, and stress management. This paper aims to discuss the role of yoga in preventing various CVDs. We aimed to review the studies on the various forms of yoga and the mechanisms that lead to cardioprotective advantages. We also discussed some of yoga's harmful side effects. We have covered two types of yoga in depth: Hatha Yoga (HY) and pranayama. We have done a thorough review of the literature using a PubMed search. Different keywords such as Yoga, cardiovascular disease (CVD), pranayama, Hatha Yoga (HY), Kapālabhāti, stress, anxiety, hypertension, coronary artery disease, asana, rate pressure product (RPP), and Double Product (DoP) were used to write the review. Yoga is a form of physical exercise that involves a series of postures, breathing techniques, and meditation practices. Recent research suggests that practicing it has potential benefits for cardiovascular health, including reducing blood pressure, improving heart rate variability, and reducing cholesterol levels. This may make it a more attractive option for people who want to improve their health and well-being. Here, we report that, according to current evidence, yoga has reduced mortality by preventing conditions that lead to the development of CVDs. However, further study is necessary to provide more convincing evidence for the widespread implementation of yoga as a treatment for CVDs.
