The Corporate Integration process Development of Enterprises Associations in the Conditions of Transformations and Changes
Authors: Gonchar V. V. , Trushkina N. V. , Yakushev O. V.
Published: August 2024

The article examines the types, meanings and processes of corporate integration, their influence on the formation and development of the corporate integration environment. The main reasons for inhibiting such development, the creation of integrated corporate structures and mechanisms, their features and significance for the stabilization of the economy of Ukraine in the conditions of transformational changes are considered.
The study of integration processes, their nature, and economic significance made it possible to generalize theoretical definitions of the very essence of integration and its types, to emphasize that in the conditions of modern economic development, one of the forms of integration development is the creation of integrated corporate structures. Integrated corporate structures are an effective form of consolidation of investment resources, knowledge-intensive technologies and production capital, that is, they are the most optimal organizational form for implementing the innovation process.
The formation of integrated corporate structures in Ukraine can become one of the tools of counteraction to foreign competitors, the creation of large export-oriented structures that can make investments in enterprises of related industries in order to guarantee their supply of raw materials, sales of products, filling the domestic market with domestic products; consolidation of financial resources of enterprises, stabilization, social condition in the regions of economic presence of companies in view of the creation of new jobs, increase of the tax base through loading of existing and deployment of new productions of their capitalization.
It is worth noting that an important factor in the stabilization and growth of the competitiveness of the national economy is the improvement of the policy of state stimulation of the activities of corporations. State policy in the corporate sector should be aimed at supporting, establishing and operating integrated corporate structures, which would ensure the saturation of the domestic as well as the world commodity market, promote the integration of production and intellectual capital, expand the scope of participation in the international division of labour and transform them into full-fledged transnational companies.

Published: August 2024

The article proves the expediency of applying the conceptual provisions of the theory of the viability of social and economic systems in the sphere of functioning and development of integrated structures. The essence of the categories of integration and disintegration processes is investigated, as a result of which simultaneous emphasis is given to their opposites and belonging to each other. It is proved that the product of the integration of integration-disintegration processes is the viable integration structures, the properties of which the elements of the union are determined by a wide range of driving forces of the internal and external sources of education, as well as of key uncertainties. The integrity of the integrated structure is ensured while respecting: the balance of interests, the rationality of the structure and the compatibility between its elements, activities, the effectiveness of diversification of risks and resource differentiation, the coherence of the internal structure and external challenges, the absence of overloading the system and exceeding the intensity of certain processes over others, the state regulation of socioeconomic transformations, reforms.
It is stated that the density of viable integration structures on the territorial unit determines the homogeneity of its economic space and the rationality of ensuring the welfare of society. Excess of the rates of intensity of integration processes over the rates of disintegration in the context of the concept of viability forms the margin of reliability and stability of the integrated structures. The development of an integrated structure is determined by the strength of the motivation of unification and establishment of links, the potential for self-sustained reproduction in the economic space, the ability to generate a synergistic effect from integration, the type of management model. The basic risks of the functioning of the integrated structures are formed, respectively: the hierarchy of the structure of their construction, the coherence between the chosen model of functioning, development and internal and external factors, the nature of interaction with the external environment, the correspondence of the goals of association with the capabilities of the entities, expediency and timeliness of integration, the degree of achievement of the maximum possible complexity of the structure . By the number of integrated companies and activities, it has been proved that the structural complexity of integrated structures is only increasing with time. It is determined that the generated synergy effect of integrated structures accumulates profitability, the redistribution of which demonstrates the significance of their budget-generating role. It is suggested to investigate the factor environment, which determines the level of viability of the integrated structures, using a key analysis factor analysis chart.
The influence of social media using on women’s willingness to marry from a risk perception perspective
Authors: Zhang Shiyu , Zhu Haoyue , Liu Zhenyi
Published: August 2024

In recent years, women’s willingness to get married continues to be depressed, and “marriage anxiety” has become a wide issue. Women living in environments with more abundant social media exhibit such characteristics even more pronounced. Based on this, this study made assumptions from the perspective of social media, contact intensity, positive policy perception and information screening ability, and studied 211 female social media users to analyze the influence of social media on their willingness to get married. The article found that the use of social media has a direct impact on women’s marriage anxiety, and decentralized and interactive communication of social media strengthens women’s perception of marriage risk, thus arousing women’s “rethink” about marriage. The stronger the female users ‘perception of positive policies on women’s rights, the stronger their ability to screen information when facing relevant news.
The Medical Intelligence And The Bioterrorism
Authors: Shay Shaul , Shay Esther
Published: August 2024

The definition of bioterrorism: "Bioterrorism refers to the intentional release of biological agents or toxins for the purpose of harming or killing humans, animals or plants with the intent to intimidate or coerce a government or civilian population to further political or social objectives." The threat from bioterrorism is real, with current reports indicating that individuals, terrorist groups and criminals have both the capability and intention to use biological agents to cause harm to society. The damage caused by such an event could reach untold magnitude, causing widespread illness and death, and instilling fear and panic on a global scale. The spread of an infectious or toxic biological agent can happen without warning, while the response to a biological event, whether naturally occurring, accidental or deliberate, relies on coordination across multiple sectors. Medical intelligence (MEDINT) is a critical component in dealing with the threat of biological terrorism. The Covid-19 crisis has imposed the need for medical intelligence to adapt to the new security reality and it is clear evidence of the crucial importance of medical intelligence for prevention and minimization of the serious consequences that epidemics may have on public health and national security on all its components. Medical intelligence related to the threat of public health emergencies, including terrorism. Intelligence implies the application of the intelligence cycle in the field of medicine. It implies the collection and processing of data, assessment of data and predictions of the risks. It involves information applied to the identification, characterization, and management of a risk, as applied to both medical and nonmedical countermeasures. The article will review the threat of biological terrorism and the contribution of medical intelligence to deal with this threat.
Origin of Chromitite-Anorthosite Interlayering in the Bushveld Complex
Authors: Maier Wolfgang D. , Barnes Sarah-Jane
Published: August 2024

An idealized stratigraphic section of the five main chromitite-bearing cyclic units of the Upper Critical Zone of the Bushveld Complex typically consists of basal chromitite overlain by pyroxenite, norite, and anorthosite. Such units can be explained by classical fractional crystallization from a Mg-rich basalt followed by injection of new magma. However, in some cases both the underlying and overlying rocks of the chromitite are anorthosite. Furthermore, most of the interstitial material in the chromitites is not pyroxene, which would be the mineral expected to crystallize with chromite, but rather it is oikocrystic plagioclase. Finally, recent age dating suggests that the cyclic units may not have been emplaced in stratigraphic order, with the upper group chromitites being older than the underlying middle group chromitites. In order to reconcile some of these data we compiled field and drill core observations from the Upper Critical Zone. Of particular interest is the MG2–MG3 interval, showing pronounced layering, abundant autoliths of various shapes and compositions, as well as flame structures and boudinage. Many of these features are typical of sedimentary mass flows, suggesting that the MG2–MG3 interval formed via granular flow of intruding chromite-orthopyroxene crystal slurries that deposited chromitite and orthopyroxenite. The heat of the new magma influx caused partial melting of the host leuconorite to produce restitic anorthosite and buoyant noritic melt. The latter infiltrated the slurry, resulting in a disequilibrium assemblage of cumulus chromite and oikocrysts of plagioclase.

Enhancing Vibration Response through Bluff Body and Splitter Plate Interaction in Fluid Flows
Authors: Zaman Izzuddin , Abdul Hadi Muhammad Amirul Harith , Manshoor Bukhari , Khalid Amir , Chan Shiau Wei , Sambu Mathan , Abuhatira Ahmed Abdalla , Sabtu Mohamad Izwan
Published: August 2024

This paper explores the profound impact of bluff body design on the phenomenon of flow-induced vibration when integrated with an attached splitter plate. The main objective is to conduct an analysis of different bluff body designs equipped with splitter plates, with a specific focus on contrasting various designs of these plates. The overall goal is to identify the optimal bluff body design that maximizes vibration response. In order to accomplish this, an extensive experimental investigation is carried out in a wind tunnel environment. Three distinct bluff body shapes – cylindrical, rectangular, and elliptical were selected for the study. Vibration response measurements were performed using a triaxial accelerometer to ensure precise and reliable data collection. The findings reveal a clear correlation between bluff body geometry and subsequent vibration response. The cylindrical bluff body shows the highest vibration response of 25.7 m/s2, followed by the rectangular bluff body of 18.9 m/s2, while the elliptical variant records the lowest response at 15.8 m/s2. Furthermore, within the subset of cylindrical bluff body configurations, it is evident that splitter plate A induces in average a 60% higher vibrations response than that of splitter plate B. This observation emphasizes the significance of splitter plate dimensions and bluff body shape in the context of flow-induced vibrations. The study uncovers noteworthy insights, highlighting how the elliptical bluff body’s streamlined design helps to reduce vibration response. Conversely, the rectangular bluff body’ sharp corners and edges amplify vibrations. Importantly, splitter plate dimensions are identified as a critical determinant of vibration response, with wider plates resulting in smaller vibration magnitudes. In conclusion, this research advances our understanding of fluid dynamics by investigating the complex interaction between bluff body design and flow-induced vibration. Beyond its academic contribution, the study holds practical implications for engineering applications. By shedding light on the factors influencing vibration response, the research informs the optimization of bluff body designs for better performance and durability.
Percurso incompleto : a política econômica externa do Brasil
Authors: Baumann, Renato
Published: August 2024

Este livro procura contribuir para o debate com relação à política econômica externa do país analisando diversos temas envolvidos, mas sem a pretensão de esgotar o tema. Como o próprio nome da obra indica, o argumento central é que tem sido percorrido um longo e diversificado caminho, em termos de disponibilidade e diversidade de políticas variadas de promoção da inserção internacional do país, mas, como os indicadores comparativos com outras economias mostram, isso tem sido feito, em alguns casos, de maneira insuficiente, às vezes pouco constante, e sem que seja claro o conjunto de políticas.
Política fiscal e proteção social na resposta à Covid-19: da resposta emergencial à recuperação econômica
Authors: Orair Rodrigo , Soares Fabio Veras
Published: August 2024

Este artigo documenta e discute as respostas fiscal e de proteção social à tripla crise (sanitária, econômica e social) associada à pandemia da Covid-19. Apesar das semelhanças nos instrumentos utilizados pelos países, a escala da resposta fiscal e das medidas de proteção social tomadas para atenuar os efeitos da crise foi bastante desigual para países com diferentes níveis de renda. Se, por um lado, a política fiscal foi capaz de reduzir os impactos negativos da pandemia sobre o crescimento, e as medidas de proteção social foram capazes de minimizar a perda de renda e preservar vínculos empregatícios, por outro, o avanço desigual da vacinação e a diferença do impacto da pandemia entre países e setores sugerem a necessidade de manutenção de uma política anticíclica que seja capaz de proteger os setores mais atingidos e, com o controle da pandemia, estimular a retomada do crescimento em bases mais inclusivas e sustentáveis.
Observações sobre as prioridades da Cooperação Amazônica: um esboço de políticas orientadas à missão no desenvolvimento da bioeconomia regional
Authors: Arima Júnior Mauro Kiithi
Published: August 2024

O objetivo do artigo é analisar, criticamente, os projetos de cooperação desenvolvidos no âmbito da Organização do Tratado de Cooperação Amazônica (OTCA), destacando a carência de iniciativas exploratórias do potencial vanguardista da biodiversidade da região e propondo novas formas de cooperação baseadas na ideia de pesquisa e inovação orientadas à missão de desenvolvimento da bioeconomia regional. Busca-se, com base em aspectos teóricos sobre cooperação internacional, demonstrar que as características dos projetos de cooperação executados e em execução na região decorrem das limitações do desenho institucional previsto no tratado. A ausência de projetos específicos de cooperação técnica e científica voltados ao uso econômico dos ativos da biodiversidade amazônica também decorreria de certa deficiência institucional da OTCA. Propõe-se, enfrentando o desafio da cooperação multilateral entre países desiguais, o redesenho institucional e a inserção de mecanismos que possibilitem pesquisa, inovação e financiamento orientados à missão de desenvolvimento da economia, que seria consistente com os objetivos de desenvolvimento socioeconômico e preservação ambiental da Amazônia. Propõe-se, igualmente, o uso do arcabouço institucional e da experiência do Brasil na criação de entidades e projetos de fomento à pesquisa direcionada a áreas específicas.

Published: August 2024

This article shows the use of a recurrent neural network LSTM whose objective was to make a 24-hour ozone forecast with data obtained from the INECC (National Institute of Ecology and Climate Change) and the validated database of the National Information System of Air Quality (SINAICA spanish acronym). The problem of air quality in the world is essential due to health problems. Currently, the techniques used to generate forecasts in monitoring stations are not accurate and do not allow generating alerts to avoid exposure to poor air quality. The state of Veracruz in Mexico has 7 air quality monitoring stations, showing that it is feasible to alternatively have a betterquality pollutant concentration forecasting system. The results obtained on the correlations of variables, although weak, positive or negative, allowed us to recognize their usefulness in the development of training in the RNN. The use of neural networks was demonstrated for the forecast of ozone concentration values in the metropolitan area of Poza Rica, using the LSTM using Python, Tensor Flow and Keras, with a good fit to the normalized pattern with an average RMSE of 0.0053 ppm of the days chosen for testing between the period from June 2019 to July 2020. Future work will consider PM10 and PM2.5.
Li Evolution among Stars of Low/Intermediate Mass: the Metal-deficient Open Cluster NGC 2204
Authors: Anthony-Twarog Barbara J. , Deliyannis Constantine P. , Steinhauer Aaron , Sun Qinghui , Twarog Bruce A.
Published: August 2024

We have analyzed high-dispersion spectra in the Li 6708 Å region for 167 stars within the anticenter cluster NGC 2204. From 105 probable members, abundance analysis of 45 evolved stars produces [Fe/H] = −0.40 ± 0.12, [Si/Fe] = 0.14 ± 0.12, [Ca/Fe] = 0.29 ± 0.07, and [Ni/Fe] = −0.12 ± 0.10, where quoted errors are standard deviations. With E(B − V) = 0.07 and (m − M)0 = 13.12, appropriate isochrones provide an excellent match from the main sequence through the tip of the giant branch for an age of 1.85 ± 0.05 Gyr. Li spectrum synthesis produces A(Li) below 1.4 at the base of the red giant branch to a detectable value of −0.4 at the tip. Six probable asymptotic giant branch stars and all but one red clump star have only Li upper limits. A rapidly rotating red giant is identified as a possible Li-rich giant, assuming it is a red clump star. Main-sequence turnoff stars have a well-defined A(Li) = 2.83 ± 0.03 (sem) down to the Li-dip wall at the predicted mass of 1.29 M
☉. Despite having the same isochronal age as the more metal-rich NGC 2506, the luminosity distribution of red giants reflects a younger morphology similar to NGC 7789, possibly indicating a deeper impact of metallicity on stellar structure and A(Li) than previously assumed. As in NGC 2506 and NGC 7789, the NGC 2204 turnoff exhibits a broad range of rotation speeds, making abundance estimation impossible for some stars. The place of the cluster within Galactic A(Li) evolution is discussed.

We investigate the emergence phase of young star clusters in the nearby spiral galaxy NGC 628. We use JWST NIRCam and MIRI observations to create spatially resolved maps of the Paα 1.87 μm and Brα 4.05 μm hydrogen recombination lines, as well as 3.3 and 7.7 μm emission from polycyclic aromatic hydrocarbons (PAHs). We extract 953 compact H ii regions and analyze the PAH emission and morphology at ∼10 pc scales in the associated photodissociation regions. While H ii regions remain compact, radial profiles help us to define three PAH morphological classes: compact (∼42%), extended (∼34%), and open (∼24%). The majority of compact and extended PAH morphologies are associated with very young star clusters (<5 Myr), while open PAH morphologies are mainly associated with star clusters older than 3 Myr. We observe a general decrease in the 3.3 and 7.7 μm PAH band emission as a function of cluster age, while their ratio remains constant with age out to 10 Myr and morphological class. The recovered PAH3.3μm/PAH7.7μm ratio is lower than values reported in the literature for reference models that consider neutral and ionized PAH populations and analyses conducted at galactic physical scales. The 3.3 and 7.7 μm bands are typically associated with neutral and ionized PAHs, respectively. While we expected neutral PAHs to be suppressed in proximity to an ionizing source, the constant PAH3.3μm/PAH7.7μm ratio would indicate that both families of molecules disrupt at similar rates in proximity to H ii regions.

We present spectropolarimetric observations of an active region recorded simultaneously in the Hα and the Ca ii 8662 Å lines. The sunspot exhibits multiple structures, including a light bridge and a region where the Ca ii 8662 Å line core is in emission. Correspondingly, the Hα line core image displays brightening in the emission region, with the spectral profiles showing elevated line cores. The stratification of the line-of-sight magnetic field is inferred through nonlocal thermodynamic equilibrium multiline inversions of the Ca ii 8662 Å line and the weak field approximation (WFA) over the Hα line. The field strength inferred from the Hα line core is consistently smaller than that inferred from inversions at

= −4.5. However, the study finds no correlation between the WFA over the core of the Hα line and that inferred from inversions at

Most studies of quasiperiodic pulsations (QPPs) in solar flares have identified characteristic periods in the 5–300 s range. Due to observational limitations, there have been few attempts to probe the <5 s period regime and understand the prevalence of such short-period QPPs. However, the Fermi Gamma-ray Burst Monitor (GBM) has observed approximately 1500 solar flares to date in high-cadence 16 Hz burst mode, providing us with an opportunity to study short-period QPPs at X-ray energies. We systematically analyze every solar flare observed by Fermi/GBM in burst mode, estimating the prevalence of QPPs in multiple X-ray energy bands. To better understand these results, we complement this with an analysis of synthetic solar flare lightcurves, both with and without oscillatory signals present. Using these synthetic lightcurves, we can understand the likely false-alarm and true-positive rates in the real solar GBM data. We do not find strong evidence for widespread short-period QPPs, indicating either a low base occurrence rate of such signatures or that their typical signal-to-noise ratios must be low—less than 1—in Fermi/GBM data. Finally, we present a selection of the most interesting potential QPP events that were identified in the GBM solar X-ray data.

Extensive multiwavelength studies of novae have been carried out in our galaxy and in M31 for decades. However, UV studies of extragalactic novae are limited, especially those in quiescence. For the first time, we present a UV catalog of novae in M31 using the archival AstroSat Ultraviolet Imaging Telescope (UVIT) imaging data. We used two image subtraction techniques to retrieve objects located deep into the M31 central region. We have found 42 novae in total in the UVIT images, 15 of which have been detected in multiple filters in the far-ultraviolet (FUV) and near-ultraviolet. The novae detected at quiescence show signatures of accretion disk from their UV spectral energy distributions, whereas those in the outburst phase show signatures of a pseudo-photosphere. A few novae were also detected in multiple epochs. Some show a near-constant FUV magnitude at quiescence, while others caught near the outburst reveal pre-eruption dips in their light curves. We conclude with a discussion on the significance of UV surveys in illuminating theoretical predictions for novae systems, including detecting the elusive early UV flash.

Young stellar objects (YSOs) represent the earliest stage in the process of star formation, offering insights that contribute to the development of models elucidating star formation and evolution. Recent advancements in deep-learning techniques have enabled significant strides in identifying special objects within vast data sets. In this paper, we present a YSO identification method based on deep-learning principles and spectra from the LAMOST. We designed a structure based on a long short-term memory network and a convolutional neural network and trained different models in two steps to identify YSO candidates. Initially, we trained a model to detect stellar spectra featuring the Hα emission line, achieving an accuracy of 98.67%. Leveraging this model, we classified 10,495,781 stellar spectra from LAMOST, yielding 76,867 candidates displaying a Hα emission line. Subsequently, we developed a YSO identification model, which achieved a recall rate of 95.81% for YSOs. Utilizing this model, we further identified 35,021 YSO candidates from the Hα emission-line candidates. Following cross validation, 3204 samples were identified as previously reported YSO candidates. We eliminated samples with low signal-to-noise ratios and M dwarfs by using the equivalent widths of the N ii and He i emission lines and visual inspection, resulting in a catalog of 20,530 YSO candidates. To facilitate future research endeavors, we provide the obtained catalogs of Hα emission-line star candidates and YSO candidates along with the code used for training the model.
Water Generation on the Moon from Solar Wind and Meteoroid Impacts

Published: August 2024

The kinetics of water formation on the lunar surface from impact-driven melts (IM) of meteoroids and recombinative desorption (RD) of solar-wind-implanted regolith grains is assessed. The ratio of water generated from RD:IM is ultimately controlled by the diffusion constant of the implanted defects. Higher diffusion activation energies of hydroxyls (-OH) result in more trapping of the implanted defects and, consequently, higher water production from IM versus RD. At diffusion activation energies >1 eV, water production from RD is negligible and IM is the dominant channel. Our results suggest that RD can be associated with the observed latitude and diurnal dependence but RD and/or micrometeorite IM are not major contributors to the water ice observed within the permanently shadowed regions (PSRs). This suggests that volcanic and/or delivery via large impactors are the more likely major sources of water on the Moon. However, our model generally agrees with the observed latitudinal dependence of the inferred OH/H2O and the overall diurnal trend from orbital observations in the infrared. In addition, our results also suggest that micrometeorites are responsible for the high content of molecular water in the glass of regolith grains.

A ring-connected microgrid cluster can be formed by connecting geographically closed microgrids for mutual power sharing to increase the system's reliability. Real-time power balance within individual microgrids and power sharing among the microgrids of an islanded microgrid cluster would be challenging during contingencies if they are not properly sized and controlled. We propose a technique to design a ring-connected microgrid cluster that has several distributed energy resources. The amount of power flow via interconnecting cables was decided considering the size of the energy storage of the neighboring microgrids. A control system was designed to minimize the effect of severe transients in the neighboring microgrids in the network. The performance of the proposed technique was verified using a ring-connected microgrid cluster with four microgrids derived based on a real distribution system. The results illustrated that the proposed ring-connected microgrid cluster could maintain the power balance of the networked microgrid during the contingencies of neighboring microgrids, increasing the resiliency of the system compared to the radial and islanded operations.

The global coronavirus pandemic sparked widespread lockdowns and travel restrictions, leading to a significant economic downturn. However, the subsequent development of vaccines prompted governments to ease restrictions and explore technology-driven strategies for tourism revival, including the use of mobile applications and augmented reality (AR). In light of the progress of AR, this study addresses the lack of AR applications for promoting tourism in Southeast Asia, particularly in Thailand and Malaysia, where language barriers hinder cross-cultural communication. Therefore, this study aims to develop a content-specific AR mobile application to enhance tourists’ exploration of cultural heritage and facilitate communication in these multicultural and Islamic-influenced regions. This study adopts the design thinking approach for a solution-based methodology. The developed AR mobile application aims to enhance the tourist experience by providing immersive and informative content specific to the culture and heritage. The prototype undergoes a heuristic evaluation by ten experts in human-computer interaction (HCI). The results show a positive consensus on many aspects, highlighting the potential of the AR mobile application to promote culture and heritage effectively. Qualitative exploration through expert feedback is recommended in future studies to refine specific elements for a universally satisfactory user experience.

Initially, we define the importance of students’ innovative capabilities and identify the potential applications of mobile interactive technologies in this context. We analyze existing research and identify limitations in meeting individualized student needs, mobile interactive social relationships, and contextual information. To address this research gap, this paper presents a specific definition of the sequential recommendation problem that aims at enhancing the development of students’ innovative capabilities and constructs a sequential recommendation model that integrates contextual information and mobile interactive social relationships. Composed of an embedding representation layer, a spatial-temporal hierarchical pooling (SHP) layer, and a fusion prediction layer, this model is designed to better capture students’ personalized learning preferences and social influences, offering precise learning resource recommendations to promote the development of their innovative capabilities.
