Einstein’s spacetime curvature and gravitational waves: Elucidating the gradient flow of scalar invariants, variations in the Ricci scalar, and gravitational wave propagation

In the general theory of relativity initially rationalized by Einstein, the gravity is considered as an occurrence ensuing from the spacetime curvature, which is in turn triggered by the presence of mass. This article provides a detailed analysis of spacetime curvature and gravitational waves, enhancing our understanding of general relativity and astrophysics. Using both analytical and numerical methods, we examined the gradient flow of scalar invariants, variations in the Ricci scalar, and gravitational wave propagation. New findings include the identification of unique curvature patterns around rotating black holes, a detailed comparison of gradient flow behavior in different spacetime geometries, and the discovery of a correlation between scalar invariant fluctuations and gravitational wave amplitudes. These findings validate numerical techniques and reveal how different parameters affect gravitational wave characteristics. While simplified models are used, the present study offers a robust framework for future research. Our work aligns with previous studies but also reveals unique aspects of wave behavior, with implications for quantum gravity and cosmology.

Application of Digital Technology for Oil and Gas Fields

The paper investigates the problem of isothermal filtration using an approximate method for solving the theory of partial differential equations. The mathematical model under consideration is nonlinear and does not lend itself to analytical methods of solution. The results obtained indicate the need for wide application in the development of oil and gas fields in the Republic of Kazakhstan. In particular, the results of the study make it possible to solve the problems of adapting mathematical models and evaluating changes in technological indicators, which are necessary attributes in the digital technology ""Information System for the Analysis of oil and Gas Field Development"" (ISAR). Many problems and mathematical problems of filtration theory arose while working on specific oil and gas fields in the western region of the Republic of Kazakhstan. The above approximate solution methods have found applications not only in filtration theory, but also in other problems (geophysics, ecology, etc.)"

Effect of various culinary treatments on the glycoalkaloid content of potato peel

Potatoes are one of the most consumed foods worldwide. During germination, glycoalkaloids (GAs) with potential bioactive properties are produced, which, at high concentrations, may have adverse health effects. Potato peels, a byproduct generated in large quantities but increasingly used in contemporary cuisine, contain significant levels of these GAs. This paper examines GA levels in potato peels after various culinary treatments (boiling, steaming, baking, air frying, conventional deep frying, and double frying) to provide new data and ensure food safety. An optimized extraction method using ultrasound-assisted extraction (UAE) was employed, followed by purification with mesostructured SBA-15 silica functionalized with octadecylsilane (C18) chains as sorbent in solid-phase extraction, prior to HPLC-DAD determination of α-solanine and α-chaconine levels in the samples. The method was validated, obtaining excellent recovery values (88 – 96 %) and low detection and quantification limits (0.3 and 1 mg/L, respectively). Upon application of the validated analytical method to the samples culinarily treated using the most common cooking techniques (boiling, steaming, baking, air frying, conventional deep frying, and double frying) at various times and temperatures, the obtained results demonstrated significant reductions (between 52 % and 84 %) in GAs content in the treated potato peels, compared to fresh samples. Statically significant degradation of these compounds was observed through baking at elevated times and temperatures (74 – 84 %), as well as both conventional deep frying and double frying (76 – 83 %).

A framework to model charge sharing and pulse pileup for virtual imaging trials of photon-counting CT

Objective.This study describes the development, validation, and integration of a detector response model that accounts for the combined effects of x-ray crosstalk, charge sharing, and pulse pileup in photon-counting detectors.Approach.The x-ray photon transport was simulated using Geant4, followed by analytical charge sharing simulation in MATLAB. The analytical simulation models charge clouds with Gaussian-distributed charge densities, which are projected on a 3×3 pixel neighborhood of interaction location to compute detected counts. For pulse pileup, a prior analytical method for redistribution of energy-binned counts was implemented for delta pulses. The x-ray photon transport and charge sharing components were validated using experimental data acquired on the CdTe-based Pixirad-1/Pixie-III detector using monoenergetic beams at 26, 33, 37, and 50 keV. The pulse pileup implementation was verified with a comparable Monte Carlo simulation. The model output without pulse pileup was used to generate spatio-energetic response matrices for efficient simulation of scanner-specific photon-counting CT (PCCT) images with DukeSim, with pulse pileup modeled as a post-processing step on simulated projections. For analysis, images for the Gammex multi-energy phantom and the XCAT chest phantom were simulated at 120 kV, both with and without pulse pileup for a range of doses (27-1344 mAs). The XCAT images were evaluated qualitatively at 120 mAs, while images for the Gammex phantom were evaluated quantitatively for all doses using measurements of attenuation coefficients and Calcium concentrations.Main results.Reasonable agreement was observed between simulated and experimental spectra with Mean Absolute Percentage Error Values (MAPE) between 10%and 31%across all incident energies and detector modes. The increased pulse pileup from increased dose affected attenuation coefficients and calcium concentrations, with an effect on calcium quantification as high as MAPE of 28%.Significance.The presented approach demonstrates the viability of the model for enabling VITs to assess and optimize the clinical performance of PCCT.

Rapid Assessment Method of Buckling Stability of Bridge Pier–Cap–Pile System Under Scour Effect

A novel analytical method for evaluating the buckling stability of the pier–cap–pile system under scour effect is proposed, and furthermore, the concept of rapid assessment of bridge buckling stability based on natural frequency is innovatively introduced in this paper. First, the total potential energy function of the bridge pier–cap–pile system is established, and the closed-form solution of structural system critical buckling load under scouring is solved according to the principle of stationary potential energy. Second, the sensitivity analyses of pier height, pier width, bending stiffness reduction in pier, pile slenderness ratio, pile bending stiffness reduction, m-value of soil and structural gravity to the buckling load are carried out. On this basis, 60 sets of sensitive parameter sample combinations are extracted by the Latin Hypercube Sampling algorithm, and a proxy model relating the critical buckling load to scour depth and the sensitive parameters are then developed using the McQuarter global optimization algorithm. Finally, the regression relationship model between the critical buckling load and the natural frequency is formed by combining the proxy model and the existing relationship between the scour depth and the first-order natural frequency. The feasibility of the proposed assessment method is demonstrated by the finite element method using a bridge case study, which provides an insight and a new means of quantitatively evaluating the safety of bridges under scour effect.

A detailed analysis of game statistics of professional tennis players: An inferential and machine learning approach.

Tennis, a widely enjoyed sport, motivates athletes and coaches to optimize training for competitive success. This retrospective predictive study examines anthropometric features and statistics of 1990 tennis players in the 2022 season, using 20,040 data points retrospectively obtained from the ATP official source after the end of the season. These data were cross-verified with information from other sources before categorisation to address any discrepancies. Employing various analytical methods, the results emphasize the strategic importance of tournament participation and gameplay for financial gains and higher rankings. Prize money analysis reveals a significant disparity favoring top players. Multivariate Analysis of Variance highlights the need to consider multiple variables for understanding ATP rankings. Multinomial Logistic Regression identifies age, height, and specific service-related metrics as key determinants, with older and taller players more likely to secure top positions. Neural Network models exhibit potential in predicting ATP Rank outcomes, particularly for ATP Rank (500). Our results argue for the use of Artificial Intelligence (AI), specifically Neural Networks, in handling complex interactions and emphasize that AI is a supportive tool in decision-making, requiring careful consideration by experienced individuals. In summary, this study enhances our understanding of ATP ranking factors, providing actionable insights for coaches, players, and stakeholders in the tennis community.

Application of computational algorithms for single-cell RNA-seq and ATAC-seq in neurodegenerative diseases.

Recent advancements in single-cell technologies, including single-cell RNA sequencing (scRNA-seq) and Assay for Transposase-Accessible Chromatin using sequencing (scATAC-seq), have greatly improved our insight into the epigenomic landscapes across various biological contexts and diseases. This paper reviews key computational tools and machine learning approaches that integrate scRNA-seq and scATAC-seq data to facilitate the alignment of transcriptomic data with chromatin accessibility profiles. Applying these integrated single-cell technologies in neurodegenerative diseases, such as Alzheimer's disease and Parkinson's disease, reveals how changes in chromatin accessibility and gene expression can illuminate pathogenic mechanisms and identify potential therapeutic targets. Despite facing challenges like data sparsity and computational demands, ongoing enhancements in scATAC-seq and scRNA-seq technologies, along with better analytical methods, continue to expand their applications. These advancements promise to revolutionize our approach to medical research and clinical diagnostics, offering a comprehensive view of cellular function and disease pathology.

Thermal stress in externally irradiated tubes of solar central receivers with a gas–particle fluidized dense suspension

One of the objectives of the new generation of concentrating solar power plants is to increase the actual temperature limit (565 °C) up to or near 1000 °C. An alternative heat transfer fluid that could help to reach this objective is the use of a fluidized dense gas–particle suspension ascending through a vertical tube. Since the predominant cause of rupture in solar receivers is the creep-fatigue damage process, which is mostly influenced by the maximum temperatures and stress experienced along the tube, the main objective of this work is to numerically study the thermomechanical behavior of a non-uniform externally irradiated tube where particles are fluidized and moves upwards. The heat transfer problem in the two media present (i.e. dense suspension of particles and tube wall) was solved separately: a Computational Particles Fluid Dynamic model solves the heat transfer in the particles, whereas a three dimensional Finite Volume model simulates the heat conduction through the tube wall to obtain the temperature profile, which serves as input to calculate the thermal stress of the tube with an analytical method. Higher thermal stresses were obtained for an absorbed power of 250 kW/m2 (σVM,max=219MPa) compared to that for an absorbed power of 500 kW/m2 (σVM,max=72MPa) due to the lower temperature difference between the front and rear sides of the tube caused by the more pronounced increase of the radiative losses in the front side of the tube compared to that at the rear side. The thermomechanical behavior of a particle receiver was compared to that of a molten salt receiver. For an incident solar flux of 500 kW/m2, the particle receiver reduced the maximum thermal stress by 73% compared to the molten salt receiver. However, the tube’s maximum temperature exceeded the working limit for stainless steel tubes. In order for the receiver to survive heat fluxes characteristic of solar power plants, research into technological solutions that allow to improve the effectiveness of the heat transfer rate from the tube to the particle flow is necessary.

I2U2 and Regional Stability in the Middle East

Abstract Participation in the Middle East Quad (I2U2) indicates that India, Israel, and the UAE are exercising “strategic autonomy” and have engineered a redirection of their foreign policy agendas. These countries no longer face any strategic dilemma in expanding their outreach, and formalising a transactional relationship for mutual strategic and geo-economic growth in the unstable and volatile Middle East. Is India’s involvement in the Middle East Quad Group beneficial to its foreign policy, keeping in view it’s cautious and ‘hands-off approach’ in the region? How far can these accords help in achieving regional stability? This paper attempts to answer these questions. It also deals with how India strikes a balance between the Abraham Accord countries and Iran, despite mutual rivalry in relation to several regional issues. This study observes that the Quad countries are driven by geo-strategic and geo-economic interests and exercise strategic autonomy in this transregional arrangement. This article employs analytical and interpretative methods through a forward-thinking conceptual framework centred on “strategic autonomy”. It concludes that India’s participation in this grouping does not hinder its ability to pursue relations with other countries, such as Iran, for its economic security. Rather, geopolitical shifts prompt national decisions on the part of different, even mutually confrontational actors, in a way that corresponds to the respective levels of their strategic autonomies or vulnerabilities. Strategic outcomes with peace dividends, such as regional multipolarity and economic diversification are identified as part of this process. such

Analytical Characteristics and Clinical Performance of Anti-Müllerian Hormone Immunoassay on the ADVIA Centaur® System: A Comparison with Other Chemiluminescent Methods

Background: Serum anti-Müllerian hormone (AMH) levels and antral follicle count are key in evaluating ovarian reserve (OR) for fertility. The performance of the Siemens Healthineers AMH assay was assessed on the ADVIA Centaur® System. Methods: Analytical characteristics, clinical performance, and method comparison studies were performed in a prospective cohort of 532 women at fertility clinics. Serum AMH levels were determined using ADVIA Centaur, Beckman Access®, and Roche Elecsys® assays. Results: The limit of quantitation for the ADVIA Centaur AMH assay was 0.030 ng/mL. Repeatability was ≤2.9% CV, within-lab repeatability was ≤3.2% CV, and reproducibility was ≤4.4% CV. Results using serum or lithium heparin sample types were equivalent. Diagnostic sensitivity across assays ranged from 77.3% to 90.2% and specificity ranged from 51.0 to 71.0%; corresponding positive and negative predictive values ranged from 66.6% to 74.3% and 74.2% to 83.0%, respectively. Receiver operating characteristic analyses demonstrated that the assays have a high probability for discriminating between diminished–normal and high OR. ADVIA and Beckman assays agreed according to ADVIA = 1.00 × Beckman + 0.014 ng/mL, τ = 0.909, while a more modest correlation of ADVIA = 1.41 × Roche − 0.024 ng/mL, τ = 0.777 was observed with Roche assay. Conclusions: The ADVIA Centaur assay demonstrates acceptable analytical characteristics and clinical performance comparable to the Roche AMH assay and is essentially interchangeable with the Beckman AMH assay for reliable OR assessment.

Compensation to Ex-Wives for Domestic Violence in Indonesia

This paper examines divorce lawsuits caused by domestic violence committed by husbands against wives, focusing on the rights of women as victims. In such cases, wives can file for divorce and demand compensation for the physical and psychological harm they have suffered. The study employs a qualitative approach with an analytical descriptive method, using the library method to gather and analyze both primary and secondary literature, including legal documents, laws, scientific articles, and case reports. The research aims to identify patterns, challenges, and solutions related to legal protection for victims of domestic violence in divorce proceedings. The findings reveal that while there are legal provisions for compensation, significant challenges remain, such as social stigma, economic dependence, and limited access to legal resources, which complicate women's ability to claim their rights. Additionally, societal attitudes and gaps in law enforcement further hinder the realization of justice for victims. The study concludes that public awareness campaigns and stronger advocacy are essential to empowering women and ensuring their rights are protected throughout the divorce process. It also emphasizes the need for stricter law enforcement to hold perpetrators accountable and provide justice for victims. This research contributes to improving legal and social frameworks for the protection of women facing domestic violence.

Extraction of methamphetamine and pseudoephedrine by modified graphene oxide solid phase extraction method coupled to HPLC-UV in urine sample.

Methamphetamine, pseudoephedrine, and related drugs are among the first drugs used for the stimulation of the central nervous system. In this study, two adsorbents based on graphene oxide (GO) were synthesized and used for the analysis of methamphetamine and pseudoephedrine. The prepared nano-adsorbents based on GO in this study were coated by polyaniline (PANI) and Fe3O4/C-nanodot/GO (magnetic adsorbent). The average size of nanoparticles (GO/PANI) was 18.43nm. The specific surface area and pore size diameter of Fe3O4/C-nanodot/GO were 22.71 m2 g- 1 and 15.23nm, respectively. Experimental variables affecting the extraction efficiency of the analytes such as pH of the sample solution, amount of adsorbent, extraction time, and type of eluents were investigated and optimized by response surface methodology. Under optimum conditions, GO/PANI and Fe3O4/C-nanodot/GO were considered appropriate solid phase extraction adsorbents for HPLC-based analyses of the studied drugs in human urine samples. However, GO/Fe3O4 nano adsorbent (Fe3O4/C-nanodot/GO) showed superior working condition than GO/PANI. The validated proposed analytical methods can be used for the quantitative determination of methamphetamine and pseudoephedrine in actual samples.

Motivations of Israeli physicians to return, or not, to Israel after their fellowship abroad.

Emigration of healthcare professionals, particularly physicians, is an unresolved "pandemic", influenced by various factors. In high-income countries, the training phase (fellowship) abroad is critical for career development, yet it poses challenges for the retention of these professionals upon their completion of training. This study aimed to identify the determinants influencing Israeli physicians' decisions to return to their home country after completing fellowship training abroad. This cross-sectional study conducted in early 2024, surveyed Israeli physicians with post-graduate training who pursued a fellowship abroad between 2013 and 2024. An anonymous survey included questions on demographics, training experience, and professional challenges. Analytical methods included descriptive statistics and regression analysis to explore factors associated with the decision to return. Of the 323 individuals surveyed, 297 met the inclusion criteria. Among them, 141 (47.5%) have returned to Israel, while 156 (52.5%) currently reside abroad, 48 (31%) of them have completed their fellowship. Respondents identified several challenges, beginning with a complex application process prior to fellowship (47% stated this as a major challenge), substantial financial burdens averaging 35,546 USD in direct out-of-pocket expenses during, and job uncertainty, with only 55% having secured positions upon return. Of the 156 Israeli fellows still abroad, 107 (69%) reported medium to low confidence in returning. Factors associated with a higher likelihood of confidence in returning to Israel included a secured job position upon return (OR 8.6, 95% CI 3.1-28.9) and having an opportunity for a position that would utilize the skills gained during the fellowship (OR 3.5, 95% CI 1.3-10.2). The decision to return to Israel after a fellowship abroad is influenced by a mix of professional, personal, and geopolitical factors. To counteract the critical issue of brain drain, it is essential to enhance occupational certainty for returning physicians. These findings highlight the urgent need for healthcare policies that provide robust support for returning professionals and address their specific challenges.

An analytical method for increasing the accuracy of the value of the Newtonian constant of gravitation

Despite hundreds of measurements of the Newtonian constant of gravitation, its accuracy remains very low. Over the past 55 years, it has improved by only one order of magnitude - from four to five digits after the decimal point. In this study, a new analytical method for improving the accuracy of estimating the value of the Newtonian constant of gravitation is proposed. Using the proposed method, its accuracy is increased by 7 orders of magnitude relative to the CODATA 2022 data. The method is based on the analytical estimate of the Planck mass, length, and time, with an accuracy of values ​​that is 5 orders of magnitude higher than their accuracy according to CODATA 2022. Such a significant increase in the accuracy of the Planck mass, length, and time values ​​was made possible by the integrated use of: 1) precision formulas for the Planck momentum; 2) representation of the speed of light in a vacuum through the Planck length and time; 3) the De Broglie principle: the moments of the Planck mass, leptons, and baryons are equal to each other; 4) high-precision characteristics of the proton. The method of analytical evaluation of Planck mass, length, and time allowed us to connect the main characteristics of the hypothetical virtual Planck particle with the main characteristics of the proton. Increasing the accuracy of the proton characteristics will entail increasing the accuracy of Planck mass, length, and time. Accordingly, the accuracy of the value of the Newtonian gravitational constant and all physical constants that can be represented through Planck mass, length, and time will be increased, which is especially important in light of the decisions of the 26th General Conference on Weights and Measures.

Engaging citizens in experiments with computational analysis of patient stories: From unwarranted reductions to meaningful insights

In recent years, citizen engagement in policy and research has gained considerable momentum. In the healthcare domain, patient narratives, through various mediums, have emerged as a valuable source of insight into the experiences of patients and the healthcare system. Recognizing the value of such textual data, diverse analytical methods have been developed, spanning from text mining to narrative analysis. This article presents experiments that combine computational methods, qualitative methods and citizen science for analyzing patients’ stories. In this article, we reflect on two experiments in which we combined these approaches, which we analyze through a generative lens. We distinguish three main effects of the experiments: they provide a platform for discussions as a 'site of controversy'; they act as 'mediator', fostering new connections and mutual understanding among participants; and they serve as 'tin opener', stimulating substantive discussions about methodological development and substantive healthcare matters. Narrative reduction, which occurs when rich narrative data is simplified into structured quantifiable forms, is not inherently problematic; instead, it can be meaningful when combined with qualitative methods and citizen science, emphasizing the importance of utilizing diverse methods to balance authenticity and gaining broader insights. The study highlights the significance of collaborative sense-making and meaning-making in interdisciplinary research. Engaging patients, their relatives, and professionals in the analytical process, facilitated by tools like word clouds, promotes engaged discussions that yield actionable insights. Further development of such interdisciplinary approaches holds promise for a more nuanced understanding of patient experiences, fostering epistemological pluralism, and refining healthcare practices.

Research on dynamic solution analysis and applications based on the Rydberg atom superheterodyne structure

This paper investigates the dynamic solution of the density matrix equation based on the Rydberg atom superheterodyne structure. Compared to the current analytical method relying on the steady-state solution, the dynamic solution is related to the Rabi frequency and the frequency of the signal to be measured. Therefore, it can comprehensively describe the instantaneous bandwidth and gain characteristics of the receiver and is in good agreement with experimental results. Additionally, we propose an atomic all-heterodyne receiver architecture that combines electric-field heterodyne and optical heterodyne techniques and demonstrates the reception and recovery of modulated signals under this architecture with linear frequency modulation (LFM) signals as an example. Our research offers interesting theoretical insights that can be applied to the performance analysis and system optimization of atomic receivers.

Forced stability studies and estimation of encapsulated ellagic acid in nano-formulations using UV-spectroscopy

Abstract There is a growing interest in dietary materials to explore their therapeutic activities. Ellagic acid is considered as a dietary supplement and is naturally present in fruits and other foods. It has anticancer, antimalarial, antiviral, antioxidant, and anti-inflammatory activities. These activities can be enhanced with nanoformulations, which can increase its oral bioavailability. However, there is a need for an economical, simple, sensitive, and robust analytical method for the estimation of entrapped ellagic acid in the nanoformulations. Therefore, the present study presents the development and validation of a UV–visible spectroscopy method for the estimation of EA in nanoformulations. The phosphate buffer (pH 7.2) and the detection wavelength of 253.5 nm were used for the method development, and its validation was performed according to the ICH Q2A (R1) guidelines. The coefficient of determination value of the developed method was found to be 0.9988 in the concentration range of 1 μg mL−1 to 6 μg mL−1. The method was found to be linear, precise, sensitive, and robust. This method can be used for the estimation of EA in nanoformulations, bulk dosage forms, and other pharmaceutical formulations.

RELATIONSHIP OF NEUTROPHIL LYMPHOCYTE RATIO WITH APPENDICITIS INCIDENCE Review of Appendicitis Patients at Ibnu Sina Hospital, Gresik Regency in 2022-2023

This study aims to analyze the relationship between the neutrophil lymphocyte ratio (NLR) and the incidence of acute appendicitis in patients at Ibnu Sina Hospital, Gresik Regency, in the 2022-2023 period. Acute appendicitis is a frequent emergency surgical condition, especially in adolescents and young adults, with the risk of complications such as perforation and peritonitis. NLR, as an indicator of inflammatory response, is considered more practical and economical than CT scans and ultrasounds, which have limited cost, accessibility, and risk of radiation exposure. This study used an observational analytical method with a cross-sectional approach on 51 appendicitis patients who underwent appendectomy. NLR data was obtained through routine blood results, with statistical analysis using SPSS to test the normality and difference in NLR values between uncomplicated appendicitis and appendicitis with complications. There was a significant difference in the mean NLR value between patients with complementary and non-complementary appendicitis, with a p < value of 0.001. The results of the ROC Curve analysis show that NLR has a high prediction value in predicting complementary appendicitis of 97.5%. This study concludes that NLR can be an effective indicator in distinguishing cases of complementary and non-complementary appendicitis and the potential of NLR as an easy and efficient screening tool in the treatment of acute appendicitis, especially in health facilities with limited resources.
