Authors:   Financial University under the Government of the Russian Federation, Moscow, Russia, Berezovka Sergei V.
Published: September 2024

This research focuses on substantiating the methodological peculiarities of evaluating investment efficiency in launching new productions and expanding existing ones. The theoretical aspects of investment efficiency and the traditional structure of investment activity stages are analyzed. It is established that traditionally, investment efficiency assessment is associated with economic efficiency. However, in the context of innovative development, the consideration of social, innovative, and other indicators becomes relevant.The generalization of existing indicators of investment efficiency allowed for the specification and delineation of their traditional structure from other indicators. As a result of this delineation, the necessity of including indicators reflecting the efficiency of investments in sustainable development is actualized, for example, by including social, environmental, and corporate (managerial) indicators. Specific features of evaluating investment efficiency in launching new productions and expanding existing ones in the context of sustainable development are specified. These include accounting for costs associated with changes in assortment and technological processes, the need for investment plan optimization, accounting for external effects, and others. It is determined that in the context of sustainable development, the principles of long-term investments, accounting for environmental, social, and managerial efficiency, as well as the openness of data on results, are brought to the forefront. These are also included in the list of features of conducting evaluations. The influence of these features on the conduct of investment efficiency assessment lies in the necessity to integrate traditional financial and economic indicators with new ones reflecting the principles of sustainable development. This requires developing a comprehensive assessment methodology that takes into account the specifics of a particular production, its mission, goals, and objectives. The author proposes a conceptual vision of a methodology for assessing investment efficiency in launching new productions and expanding existing ones in the context of sustainable business development. Based on the results of the conducted research, it is concluded that the development and implementation of such assessment methodologies will allow enterprises to make more informed decisions that contribute to sustainable business development and achieving long-term goals.

Dynamic Programming, Neuro-Dynamic Programming, Rollout Method and Model Predictive Control to Optimal Control of a Fermentation Process
Authors: Ilkova Tatiana , Petrov Mitko
Published: September 2024

This work presents the use of dynamic programming (DP), neuro-dynamic programming (NDP), rollout algorithm (RA) and model predictive control (MPC) for optimal control of batch cultivation of the yeast Kluyveromyces marxianus var. lactis MC5. DP is a widespread method for solving problems related to optimization and optimal process control. To reduce the “curse of dimensionality”, NDP has been implemented as an alternative. In NDP, a neural network is used to solve the dimensionality problem. A simpler NDP method, called RA, is used to approximate the optimal cost through the cost of a relatively good suboptimal policy, called the baseline policy. RA is a suboptimal method for deterministic and stochastic problems that can be solved by DP. In this paper we also present off-line MPC  technique for tracking of constrained fermentation systems and it overcomes the problem by off-line optimizations prior to implementation. MPC is used to provide perturbation feedback and it is developed theoretical on base a controller as an illustration how we can avoid disturbances in the process optimisation. The developed control algorithm-combined NDP and MPC ensures maximum biomass production at the end of the process and feedback during disturbances and process stability and shows that robust stability can be ensured.
Dynamics of a SVEIR Epidemic Model with a Delay in Diagnosis in a Changing Environment
Authors: Dicko Hamadoum , Traoré Ali , Ouedraogo Désiré
Published: September 2024

A SVEIR epidemic model with a delay in diagnosis is studied in a constant and variable environment. The mathematical analysis shows that the dynamics of the model in the constant environment are completely determined by the magnitude of the delay-induced reproduction number . We established that if  < 1, the disease-free equilibrium is globally asymptotically stable, and when  > 1 the endemic equilibrium is globally asymptotically stable. In the variable environment, the model undergoes a transcritical bifurcation for = 1 leading to changes in the stability of the equilibrium points. The analytical effect of the delays in epidemic diagnosis is investigated. A minimum diagnosis rate αmin has been determined to face or control the disease effectively. Finally, numerical illustrations were presented to support the theoretical results.
A Review on Analytical Methods for Determination of Azithromycin
Authors: M. S. Jamur Jasim
Published: September 2024

Azithromycin treatment has been associated with a decrease in ventilation time and death in several viral infections. It possesses immune-modulating properties, including the capacity to inhibit cytokine production, preserve the integrity of epithelial cells, and prevent lung fibrosis. Primary hepatic metabolism is the process by which drugs are broken down into inactive metabolites that keep their biological effects. These prompted numerous studies and publications that used a variety of analytical techniques to find, evaluate, and investigate azithromycin and its metabolites. This review aims to provide an overview of the various analytical techniques—such as voltammetry, flow injection, hyphenated mass spectrometry, and chromatography—that have been published for the years 1990 to 2020 in order to determine azithromycin. While azithromycin was most commonly quantified using high-performance liquid chromatography, the study's results indicate that when compared to alternative techniques, liquid chromatography-mass spectrometry had the highest sensitivity, with a limit of detection of 0.0005 µg/mL.

Published: September 2024

The formation of metabolic changes is based on many factors. In particular, the infectious theory of the development of metabolic “breakdowns” has not lost its relevance. In this regard, many scientists are investigating the role of various microorganisms in the pathogenesis of metabolic syndrome. The review provides the results of current research on the role of Helicobacter pylori (as one of the most well-known and widespread bacterial pathogens) in the pathogenesis of metabolic syndrome. However, the results of scientific work are sometimes contradictory, which dictates the need for novel further research to clarify the characteristics of the influence Helicobacter pylori on the formation of various components of the metabolic syndrome.

Authors:   Universitas Pembangunan Nasional Veteran Jakarta, Hayati Kumala , Afriani Anindita Lintangdesi ,   Universitas Pembangunan Nasional Veteran Jakarta
Published: September 2024

For fans outside of South Korea, the existence of social media can open the possibility to follow all their idol activities and express their identity as fans freely because not all community can accept them. LINE is a medium of information exchange that forms a fan culture as a form of identity consumption of the fans. This research uses a qualitative method with Creswell's constructivism paradigm discussing identity construction among members of Bandung EXO - L community. LINE chat group is a discussion forum to learn how to support idols by conducting virtual fangirling activities that become the lifestyle of community members. Thus, the community environment shapes both verbal and non-verbal communication between community members. This has an impact on the emergence of loyal and active feelings possessed by community members. This loyalty is interpreted as obligations for fan identity because consuming EXO related stuffs is not only based on the work produced, but as an absolute identity.

A meta-analysis on the relationship between subjective cognitive failures as measured by the cognitive failures questionnaire (CFQ) and objective performance on executive function tasks
Authors: Goodhew Stephanie C. , Edwards Mark
Published: September 2024

The Cognitive Failures Questionnaire (CFQ) has been widely used as a measure of subjective cognitive function in everyday life for decades. However, the evidence on how it relates to objective performance on executive function tasks is mixed. One possible reason for these mixed results is that the CFQ has selective relationships with some aspects of executive function and not others. Here, therefore, we classified tasks according to an influential framework of executive functions—switching, updating, inhibition, and we also considered the Sustained Attention to Response Task (SART) as a category because it was custom designed to gauge cognitive failures. We synthesized a large body of available evidence and performed four Bayesian meta-analyses on the relationship between CFQ scores and objective performance on executive function tasks in these four categories. Results suggested that CFQ scores were associated with objective performance on SART (18 effect sizes, μ = −.19, BF10 = 18.03, i.e., 18.03 times more evidence of a relationship versus no relationship), updating working memory (49 effect sizes, μ = −.06, BF10 = 17.80), and inhibition tasks (41 effect sizes, μ = −.07, BF10 = 15.40), whereas there was not definitive evidence regarding switching (34 effect sizes, μ = −.06, BF10 = .50, i.e., two times greater evidence for no relationship). This suggests that subjective cognitive function can predict objective performance on at least some executive function tasks. We discuss methodological and theoretical factors that constrain the maximum observable correlation and consider the relative insights that subjective measures versus task performance provide.

Published: September 2024

Satellite-based land-use classification plays a crucial role in various Earth observation applications, ranging from environmental monitoring to disaster management. This study presents a comparative analysis of machine learning techniques applied to land cover classification using Landsat-9 and Sentinel-2 satellite imagery in the Reyhanlı district in southern Türkiye. Three different classification algorithms, Random Forest (RF), Support Vector Machine (SVM), and Maximum Likelihood Classification (MLC), were evaluated for their ability to distinguish different land cover classes. High resolution multispectral satellite imagery processed under the same conditions using Geographic Information System (GIS) software was utilized in this study. Visual inspection and statistical evaluation, including overall accuracy and kappa coefficient, were employed to assess classification performance. The classification of Sentinel-2 and Landsat-9 satellite imagery using different machine learning algorithms resulted in the highest overall accuracy (OA = 0.911, Kappa = 0.879) for Sentinel 2 imagery with the RF algorithm. These findings highlight the importance of satellite image selection and algorithm optimization for accurate land cover mapping. This study provides valuable insights for local planners and authorities and underscores the potential of Sentinel-2 imagery combined with machine learning techniques for effective land-use classification and monitoring.

Sick Building Syndrome Overview- UK’S Indoor Sick Building Syndrome Formation Analysis
Authors: Chukwudi OBI Ifeanyi
Published: September 2024

Building-related illnesses pose a critical risk to public health and have consistently been a source of concern. The illnesses are collectively referred to as Sick Building Syndrome (SBS) and are used to elaborate on a situation in which the occupants of a house experience headaches discomfort-related effects or symptoms of air borne diseases that seems to be connected to the time spent in houses. Symptoms are many, but in general, occupants may experience throat, eye, and nose discomfort, as well as fatigue and, on occasion, dizziness. The increased prevalence of this syndrome has prompted substantial research. Although there is no known specific cause of SBS, some experts have concluded that indoor pollutants have a significant role in exacerbating the illness. The sources of indoor pollutants include biological contaminants, chemical contaminants, and particulate matter. These contaminants include bacteria, volatile organic compounds (VOCs), and dust, respectively. This study will examine the role of indoor pollutants in Sick Building Syndrome symptoms, investigate the causes and effects, and recent progress in understanding and controlling SBS caused by these contaminants.And also outlines an overview of the UK’s SBS issues.

Growing improved crops and social justice: A contextualisation of ubuntu principles for smallholder farmers
Authors: Serugo Paulous
Published: September 2024

Improved crops are being promoted in many de­veloping countries to increase food production and realise economic benefits associated with them. The changes in farm­ing being introduced are affecting the social values in food production. The paper examines how the new crops affect the Ubuntu values important for the realisation of social justice of smallholder farmers. The study used mixed methods case study utilising a questionnaire, focus group discussion, and in-depth interviews. Three themes were the main focus with regard to Ubuntu as an analytic lens for social justice concerns of smallholder farmers: access to land, crops, labour and gar­dening, and food access and distribution. The findings show that Ubuntu values are being stifled with the commoditisation of farming processes and systems. At the same time, individ­ualism associated with growing improved crops is threaten­ing food access and distribution, as Ubuntu values of interde­pendence, solidarity, unity, compassion, empathy, and to­getherness no longer influence processes in food systems. The results suggest the need for the incorporation and recognition of the values of Ubuntu/Obuntu Bulamu in promoting im­proved crops. This will contribute to addressing smallholder farmers' social justice concerns.

Violence, in the same measure as shortage of adequately qualified teaching staff, inadequate infrastructure for teaching and learning, and inadequate capacity to develop curricula, poses a significant threat to the quality of education in the higher education institutions in Zambia. Through the lens of a theoretical framework, this research paper delves into the effects of violence on the educational landscape by examining the perceptions of students, faculty, and administrators. With a comprehensive approach that includes 100 interviews and 10 focus group discussions with students, faculty, and administrators to explore their perceptions of violence and its effects on the quality of education, this study aims to shed light on the intricate dynamics between violence and education quality. Violence in higher education institutions is a multifaceted issue with significant ramifications for the quality of education provided. In Zambia, where higher education plays a crucial role in national development, understanding the dynamics of violence within these institutions and its effects on educational quality is imperative. This theoretical framework aims to provide a structured approach to investigating the relationship between violence and the quality of higher education in Zambia, drawing on existing literature and secondary data collected by the Higher Education Authority (HEA). By employing a theoretical framework that integrates diverse perspectives, this study aims to provide a comprehensive understanding of violence in Zambian higher education institutions and its implications for the quality of education. The findings will inform evidence-based interventions to address violence and enhance the educational experience for students and faculty.
Type Ia Supernovae Can Arise from the Detonations of Both Stars in a Double Degenerate Binary

The precise origin of Type Ia supernovae (SNe Ia) is unknown despite their value to numerous areas in astronomy. While it is a long-standing consensus that they arise from the explosion of a carbon/oxygen white dwarf, the exact progenitor configurations and explosion mechanisms that lead to SNe Ia are still debated. One popular theory is the double detonation, in which a helium layer, accreted from a binary companion, detonates on the surface of the primary star, leading to a converging shock-induced detonation of the underlying core. It has recently been seen in simulations that a helium-rich degenerate companion may undergo its own explosion triggered by the impact from the ejecta of the primary star. We show 2D simulations that approximate a white dwarf undergoing a double detonation, which triggers the explosion of the degenerate companion, leading to either a triple or quadruple detonation. We also present the first multidimensional radiative transfer results from the triple and quadruple detonation scenario. We find that within a range of mass configurations of the degenerate binary, the synthetic light curves and spectra of these events match observations as well as theoretical models of isolated double detonations do. Notably, double and quadruple detonations that are spectrally similar and reach the same peak brightnesses have drastically different ejecta masses and produce different amounts of Si- and Fe-group elements. Further understanding of this scenario is needed in order to determine if at least some observed SNe Ia actually originate from two stars exploding.

The distribution of chemical species in protoplanetary disks around young stars, especially their division between gas and solid phases, fundamentally shapes the composition of future planets and planetesimals. This distribution is likely affected by entrapment, a mechanism whereby volatile species are mechanically or chemically bound within a less volatile ice. In this study, we investigate the entrapment efficiencies of four hypervolatiles (CH4, CO, N2, and Ar) in multicomponent water ice mixtures deposited at different temperatures and mixture ratios. At low ice deposition temperatures, we observe small differences in entrapment efficiency (CH4>CO>N2∼Ar) up to a factor of two across species. The differences in entrapment between species increase by up to an order of magnitude with increasing deposition temperature. The relative entrapment efficiencies are also impacted by changes in the overall hypervolatile concentration of the ice mixtures. Collectively, these experiments suggest that relative entrapment efficiencies are mainly regulated by small differences in binding energies to the ice matrix, though competition for the best sites also influences entrapment in more concentrated ices. We use these results to better inform interpretations of hypervolatile observations in comets and related objects.
Magnetosonic Waves Excited by Maxwellian Ring Protons in Space Plasma Environment

A comprehensive theoretical model for a homogeneous plasma system of hot, tenuous Maxwellian ring-distributed protons and the cold background of Maxwellian ions and electrons is used to study the resonant instabilities of magnetosonic (MS) waves. The perpendicular velocity integrals associated with the Maxwellian ring distribution have no analytical solution, hence, are solved numerically, while the parallel velocity integrals are solved analytically by invoking series expansion of the plasma dispersion function. For the plasma parameters relevant to Earth’s inner magnetosphere, the theoretical model generates MS waves with frequencies from 5 times the local proton cyclotron frequency to above the lower hybrid frequency for a propagation angle of 89.5°. Hydrogen (H+) band electromagnetic ion cyclotron waves are also excited by the Maxwellian ring protons for the same set of plasma parameters. A detailed analysis reveals that a sufficiently large ring velocity, as well as a smaller perpendicular and parallel thermal velocity, can enhance the MS wave growth. The study also explores the role of background plasma parameters in modulating the waves. The present theoretical model reproduces the harmonics of the MS waves observed by the Van Allen Probes in the Earth’s inner magnetosphere. Further, the model can generate MS waves in other plasma environments, e.g., Mars, where the presence of ring protons has been established by MAVEN in connection with the MS wave observations.

Coronal jets are one of the most common eruptive activities in the solar atmosphere. They are related to rich physics processes, including, but not limited to, magnetic reconnection, flaring, instabilities, and plasma heating. Automated identification of off-limb coronal jets has been difficult due to their abundant nature, complex appearance, and relatively small size compared to other features in the corona. In this paper, we present an automated jet identification algorithm (AJIA) that utilizes true and fake jets previously detected by a laborious semiautomated jet detection algorithm (SAJIA) as the input of an image segmentation neural network U-NET. It is found that AJIA can achieve a much higher (0.81) detecting precision than SAJIA (0.34) while giving the possibility of whether each pixel in an input image belongs to a jet. We demonstrate that with the aid of artificial neural networks, AJIA can enable fast, accurate, and real-time off-limb coronal jet identification from Solar Dynamics Observatory/Atmospheric Imaging Assembly 304 Å observations, which are essential in studying the collective and long-term behavior of coronal jets and their relation to the solar activity cycles.

We report the serendipitous multiwavelength discovery of a candidate dual black hole system with a separation of ∼100 pc, in the gas-rich luminous infrared galaxy MCG-03-34-64 (z = 0.016). Hubble Space Telescope/Advanced Camera for Surveys observations show three distinct optical centroids in the [O iii] narrow-band and F814W images. Subsequent analysis of Chandra/ACIS data shows two spatially resolved peaks of equal intensity in the neutral Fe Kα (6.2–6.6 keV) band, while high-resolution radio continuum observations with the Very Large Array at 8.46 GHz (3.6 cm band) show two spatially coincident radio peaks. Fast shocks as the ionizing source seem unlikely, given the energies required for the production of Fe Kα. If confirmed, the separation of ∼100 pc would represent the closest dual active galactic nuclei reported to date with spatially resolved, multiwavelength observations.
A Two-month Mini-moon: 2024 PT5 Captured by Earth from September to November

Near-Earth objects (NEOs) that follow horseshoe paths, and approach our planet at close range and low relative velocity, may undergo mini-moon events in which their geocentric energy becomes negative for hours, days or months, but without completing one revolution around Earth while bound. An example of NEO experiencing such a temporarily captured flyby is 2022 NX1, which was a short-lived mini-moon in 1981 and 2022. Here, we show that the recently discovered small body 2024 PT5 follows a horseshoe path and it will become a mini-moon in 2024, from September 29 until November 25.
