Coherent Plasma in a Lattice
Authors: Gamberale Luca , Modanese Giovanni
Published: February 2023

We present a fully second-quantized calculation showing the emergence of spontaneous coherent configurations of the electromagnetic field interacting with charged bosons in a regular lattice. The bosons tend to oscillate at their plasma frequency, and in addition are subjected to electrostatic forces which keep them confined close to the lattice sites while causing a frequency shift in the oscillation. Under certain conditions upon these frequencies, we find that a suitably defined set of coherent states (coherent both in the field and matter degrees of freedom) exhibit a negative energy gap with respect to the perturbative ground state. This is true in the RWA approximation and for position-independent fields to both the first and second order in the interaction Hamiltonian. We compare this result with other recent findings from cavity QED, and note that (1) consideration of full 3D wavefunctions and a careful definition of the coherent states are essential for obtaining the energy gap, and (2) although our calculation is made in reference to bosons, it may apply to protons bound in a crystal matrix as well if their density is very low compared to the density of available states.
A U(6) Boson Model for Deformed Nuclei
Authors: Martinou Andriana
Published: February 2023

The Interacting Boson Model is one of the most famous group-theoretical nuclear models, which established the use of the U(6) symmetry in nuclei, built upon the s,d bosons, which derive by nucleon pairs. In this article, it is suggested that the symmetric pairs of the valence harmonic oscillator quanta can be used approximately as the s and d bosons of a new U(6) Boson Model, applicable in medium mass and heavy nuclei. The main consequence of this interpretation is that the number of bosons is the number of the pairs of the valence harmonic oscillator quanta, which occur from the occupation of the Shell Model orbitals by nucleons.
FogTrust: Fog-Integrated Multi-Leveled Trust Management Mechanism for Internet of Things

Published: February 2023

The Internet of Things (IoT) is widely used to reduce human dependence. It is a network of interconnected smart devices with internet connectivity that can send and receive data. However, the rapid growth of IoT devices has raised security and privacy concerns, with the identification and removal of compromised and malicious nodes being a major challenge. To overcome this, a lightweight trust management mechanism called FogTrust is proposed. It has a multi-layer architecture that includes edge nodes, a trusted agent, and a fog layer. The trust agent acts as an intermediary authority, communicating with both IoT nodes and the fog layer for computation. This reduces the burden on nodes and ensures a trustworthy environment. The trust agent calculates the trust degree and transmits it to the fog layer, which uses encryption to maintain integrity. The encrypted value is shared with the trust agent for aggregation to improve the trust degree’s accuracy. The performance of the FogTrust approach was evaluated against various potential attacks, including On-off, Good-mouthing, and Bad-mouthing. The simulation results demonstrate that it effectively assigns low trust degrees to malicious nodes in different scenarios, even with varying percentages of malicious nodes in the network.
Long Non-Coding RNA MEG3 in Metal Carcinogenesis
Authors: Zhang Zhuo , Shi Sophia , Li Jingxia , Costa Max
Published: February 2023

Most transcripts from human genomes are non-coding RNAs (ncRNAs) that are not translated into proteins. ncRNAs are divided into long (lncRNAs) and small non-coding RNAs (sncRNAs). LncRNAs regulate their target genes both transcriptionally and post-transcriptionally through interactions with proteins, RNAs, and DNAs. Maternally expressed gene 3 (MEG3), a lncRNA, functions as a tumor suppressor. MEG3 regulates cell proliferation, cell cycle, apoptosis, hypoxia, autophagy, and many other processes involved in tumor development. MEG3 is downregulated in various cancer cell lines and primary human cancers. Heavy metals, such as hexavalent chromium (Cr(VI)), arsenic, nickel, and cadmium, are confirmed human carcinogens. The exposure of cells to these metals causes a variety of cancers. Among them, lung cancer is the one that can be induced by exposure to all of these metals. In vitro studies have demonstrated that the chronic exposure of normal human bronchial epithelial cells (BEAS-2B) to these metals can cause malignant cell transformation. Metal-transformed cells have the capability to cause an increase in cell proliferation, resistance to apoptosis, elevated migration and invasion, and properties of cancer stem-like cells. Studies have revealed that MEG is downregulated in Cr(VI)-transformed cells, nickel-transformed cells, and cadmium (Cd)-transformed cells. The forced expression of MEG3 reduces the migration and invasion of Cr(VI)-transformed cells through the downregulation of the neuronal precursor of developmentally downregulated protein 9 (NEDD9). MEG3 suppresses the malignant cell transformation of nickel-transformed cells. The overexpression of MEG3 decreases Bcl-xL, causing reduced apoptosis resistance in Cd-transformed cells. This paper reviews the current knowledge of lncRNA MEG3 in metal carcinogenesis.

In routine measurements, the length of the analysis time and nfumber of samples analysed during a time unit are crucial parameters, which are especially important for the food analysis, particularly in the case of mycotoxin determinations. High-resolution equipment, including time-of-flight or Orbitrap analyzators, can provide stable instrumental background for high-throughput analyses. In this report, a short, 1 min MS-based multi-mycotoxin method was developed with the application of a short column as a reduced chromatographic separation, taking advantages of the multiplexing and high-resolution capability of the QExactive Orbitrap MS possessing sub-1 ppm mass accuracy. The performance of the method was evaluated regarding selectivity, LOD, LOQ, linearity, matrix effect, and recovery, and compared to a UHPLC-MS/MS method. The final multiplexing method was able to quantify 11 mycotoxins in defined ranges (aflatoxins (corn, 2.8–600 μg/kg; wheat, 1.5–350 μg/kg), deoxynivalenol (corn, 640–9600 μg/kg; wheat, 128–3500 μg/kg), fumonisins (corn, 20–1500 μg/kg; wheat, 30–3500 μg/kg), HT-2 (corn, 64–5200 μg/kg; wheat, 61–3500 μg/kg), T-2 (corn, 10–800 μg/kg; wheat, 4–250 μg/kg), ochratoxin (corn, 4.7–600 μg/kg; wheat, 1–1000 μg/kg), zearalenone (corn, 64–4800 μg/kg; wheat, 4–500 μg/kg)) within one minute in corn and wheat matrices at the MRL levels stated by the European Union.

Published: February 2023

Aflatoxin B1 (AFB1) exhibits the most potent mutagenic and carcinogenic activity among aflatoxins. For this reason, AFB1 is recognized as a human group 1 carcinogen by the International Agency of Research on Cancer. Consequently, it is essential to determine its properties and behavior in different chemical systems. The chemical properties of AFB1 can be explored using computational chemistry, which has been employed complementarily to experimental investigations. The present review includes in silico studies (semiempirical, Hartree–Fock, DFT, molecular docking, and molecular dynamics) conducted from the first computational study in 1974 to the present (2022). This work was performed, considering the following groups: (a) molecular properties of AFB1 (structural, energy, solvent effects, ground and the excited state, atomic charges, among others); (b) theoretical investigations of AFB1 (degradation, quantification, reactivity, among others); (c) molecular interactions with inorganic compounds (Ag+, Zn2+, and Mg2+); (d) molecular interactions with environmentally compounds (clays); and (e) molecular interactions with biological compounds (DNA, enzymes, cyclodextrins, glucans, among others). Accordingly, in this work, we provide to the stakeholder the knowledge of toxicity of types of AFB1-derivatives, the structure–activity relationships manifested by the bonds between AFB1 and DNA or proteins, and the types of strategies that have been employed to quantify, detect, and eliminate the AFB1 molecule.

Published: February 2023

Resistance monitoring in the Asian corn borer, Ostrinia furnacalis, is necessary to accommodate the commercial introduction and stewardship of Bt maize in China. The susceptibility of 56 O. furnacalis field populations, collected between 2015 and 2021 from the corn belt regions of China, to Cry1Ab and Cry1F toxins was determined. Neonate larvae (within 12 h after hatching) were placed on the surface of semi-artificial agar-free diet incorporating a series of concentrations of purified toxins, and mortality was evaluated after 7d. The median lethal concentration (LC50) values of Cry1Ab and Cry1F were 0.05 to 0.37 µg/g (protein/diet) and 0.10 to 1.22 µg/g, respectively. Although interpopulation variation in susceptibility to the toxins was observed, the magnitude of the differences was 5.8-fold and 8.3-fold for Cry1Ab and Cry1F, respectively. These results suggested that the observed susceptibility differences reflect natural geographical variation in response and not variation caused by prior exposure to selection pressures. Therefore, the O. furnacalis populations were apparently still susceptible to Cry1Ab and Cry1F across their range within China. The monitoring data established here will serve as a comparative reference for early warning signs of field-evolved resistance after the cultivation of Bt maize in China.

The study aims to assess the usefulness of human T-cell leukemia virus type 1 (HTLV-1)-infected cell analysis using flow cytometry (HAS-Flow) as a monitoring method for adult T-cell leukemia (ATL) development in HTLV-1-positive patients with rheumatoid arthritis (RA) under treatment with antirheumatic therapies. A total of 13 HTLV-1-negative and 57 HTLV-1-positive RA patients participated in this study, which was used to collect clinical and laboratory data, including HAS-Flow and HTLV-1 proviral load (PVL), which were then compared between the two groups. CADM1 expression on CD4+ cells in peripheral blood (PB) was used to identify HTLV-1-infected cells. The population of CADM1+ CD4+ cells was significantly higher in HTLV-1-positive RA patients compared to HTLV-1-negative RA patients. The population of CADM1+ CD4+ cells was correlated with HTLV-1 PVL values. There were no antirheumatic therapies affecting both the expression of CADM1 on CD4+ cells and PVLs. Six HTLV-1-positive RA patients who indicated both high HTLV-1 PVL and a predominant pattern of CADM1+ CD7neg CD4+ cells in HAS-Flow can be classified as high-risk for ATL progression. HAS-Flow could be a useful method for monitoring high-risk HTLV-1-positive RA patients who are at risk of developing ATL during antirheumatic therapies.
Priority of Vaccination of the Population against COVID-19: Moral Principles
Authors: Rashi Tsuriel
Published: February 2023

The COVID-19 pandemic broke out at the end of 2019 and throughout 2020 there were intensive international efforts to find a vaccine for the disease, which has already led to the deaths of over 6 million people. In December 2020, several pharmaceutical companies announced that they had succeeded in producing an effective vaccine and after approval by the various regulatory bodies, countries started to vaccinate their citizens. With the start of the global campaign to vaccinate the world’s population against COVID-19, there was a strong renewal of the debate about prioritizing the population for the vaccination. This article presents the moral approaches to this issue and their consequences.
Attitudes of Healthcare Workers in Israel towards the Fourth Dose of COVID-19 Vaccine
Authors: Ramot Shira , Tal Orna
Published: February 2023

Attitudes of healthcare workers (HCWs) toward vaccines are extremely important for increasing vaccination coverage. We conducted a cross-sectional study at the beginning of the fourth COVID-19 vaccination dose campaign among 124 HCWs to evaluate attitudes towards the fourth dose and willingness to get vaccinated. At that time, Israel was the first country to approve the fourth vaccine dose. Most women were unwilling to get the fourth vaccine dose compared to men; 53.9% of physicians were unwilling to get vaccinated compared to 83.3% of nurses and 69% of other HCWs professions. The most frequent concerns regarding the vaccine were its efficacy, benefit, and necessity. The perceived risk and perceived severity of the health risk involved with getting vaccinated with the fourth dose were higher among HCWs who stated that they would not get vaccinated compared to those who were vaccinated or intended to get vaccinated. In contrast, HCWs who were vaccinated with the fourth dose, or those who were planning to get vaccinated, gave higher scores to the perceived benefit of the booster, its advantages, its perceived safety, its ability to protect from severe illness, and the perceived extent of scientific information about the risk associated with the booster. A logistic regression model revealed that perception of the fourth dose’s benefits and risk significantly predict the willingness of HCWs to get vaccinated. Willingness to vaccinate their own children, acceptance of a hypothetical annual booster vaccine, and having less severe adverse effects after prior vaccination were also associated with willingness to get the fourth dose. These findings could help policy makers in developing strategies to expand the acceptance and coverage of the COVID-19 booster doses.

Published: February 2023

We evaluated four DNA vaccine candidates for their ability to produce virus-like particles (VLPs) and elicit a protective immune response against Foot-and-mouth disease virus (FMDV) in cattle. Two traditional DNA plasmids and two DNA minicircle constructs were evaluated. Both the pTarget O1P1-3C plasmid and O1P1-3C minicircle encoded a wild-type FMDV 3C protease to process the P1-2A polypeptide, whereas the O1P1-HIV-3CT minicircle used an HIV-1 ribosomal frameshift to down-regulate expression of a mutant 3C protease. A modified pTarget plasmid with a reduced backbone size, mpTarget O1P1-3CLT, used a 3C protease containing two mutations reported to enhance expression. All constructs produced mature FMDV P1 cleavage products in transfected cells, as seen by western blot analysis. Three constructs, O1P1-3C minicircles, pTarget O1P1-3C, and mpTarget O1P1-3CLT plasmids, produced intracellular VLP crystalline arrays detected by electron microscopy. Despite VLP formation in vitro, none of the DNA vaccine candidates elicited protection from clinical disease when administered independently. Administration of pTarget O1P1-3C plasmid enhanced neutralizing antibody titers when used as a priming dose prior to administration of a conditionally licensed adenovirus-vectored FMD vaccine. Further work is needed to develop these DNA plasmid-based constructs into standalone FMD vaccines in cattle.

Published: February 2023

This study proposed a spatial wave measurement method based on a U-net convolutional neural network. First, frame images are extracted from a video collected by a physical model experiment, and a dataset of spatial wave measurements is created and extended using a data enhancement method. A U-net convolutional neural network is built to extract the spatial wave information of the images; evidently, the segmented water level is close to that of the original image. Next, the U-net convolutional neural network is compared with the sensor, pixel recognition, and Canny edge detection methods. Pixel recognition results reveal that the maximum and minimum errors of the U-net convolutional neural network are 3.92% and 1.05%, those of the Canny edge detection are 5.97% and 1.33%, and those of the sensor are 11.8% and 1.6%, respectively. Finally, the nonlinear characteristic quantities of waves are measured using the proposed U-net convolutional neural network. The kurtosis and asymmetry calculated in the spatial domain are slightly larger than those calculated in the time domain, whereas the skewness calculated in the spatial domain is smaller than that calculated in the time domain. The asymmetry and kurtosis increase with an increase in wave height and period, whereas the skewness increases with an increase in wave height but decreases with an increase in period.

Published: February 2023

The annular flume is an ideal hydrodynamic test device for studying river sediment, and it has been widely used in recent years to study the movement patterns of sediment and other particulate matter. Annular flumes have made outstanding contributions to research in fields related to sediment transport and the diffusion and migration of pollutants. The existence of circumfluence structures in annular flumes leads to complex and variable flow structures. To obtain a more stable and controllable water flow structure, a sophisticated three-dimensional mathematical model based on the Fluent software was established to study the development law of water flow structure in the flume by changing the size of the annular flume speed ratio. The results show the following: (1) The overall trend of the simulation results basically matched with the measured results; the average relative error was 3.54% and the Nash efficiency coefficient was 0.9934, close to 1. The model calculation data were highly credible. (2) The axial flow velocity of the water tank gradually showed a “U”-shape distribution with the increase in the speed ratio. (3) When the speed ratio was R ≤ 0.17 (where the speed ratio R refers to the ratio of annular groove to shear ring speed), there was only one vortex in the tank; when the speed ratio was R > 0.17, there were multiple vortices in the tank, and the flow pattern was more complicated. (4) When the rotational speed ratio R = 0.28, the secondary flow intensity of the annular flume reached the lowest point, which was only 39.28% of the secondary flow intensity of the conventional annular flume. (5) It was determined that the annular flume water flow structure was most stable and controllable when the rotational speed ratio R = 0.24. The results of the study can provide a further theoretical basis for research on sediment dynamics and its related fields conducted by applying an annular flume.
Spatial Distribution and Sources of Rare Earth Elements in Urban River Water: The Indicators of Anthropogenic Inputs
Authors: Gao Xi , Han Guilin , Liu Jinke , Zhang Shitong
Published: February 2023

Rare earth element (REE) concentrations in river water reflect both local geological background and the intensity of anthropogenic activities. The increasing demand for high-tech applications is accompanied by an increase in REEs in water environments, especially in urban regions. Therefore, the dissolved REEs in a typical urban river (Yongding River) were analyzed to reveal the influence of anthropogenic inputs. It was found that the sum of dissolved REE (ΣREE) concentrations in river water were 6.27~86.26 ng L−1 (mean 31.05 ng L−1). The spatial distribution of REEs is significantly affected by both natural processes and human activities. To eliminate the effect of upstream land use on downstream measurements, this study established a 500 m buffer zone alongside the river and identified the anthropogenic origin of REEs through correlations among land use proportions within the buffer zone, the population density, and REEs. The Post-Archean Australian Shale (PAAS)-normalized REEs revealed pronouncedly positive Gd anomalies in the range 0.30~20.16 in all river samples. Spearman correlation analysis indicated that the proportion of cultivated land was positively correlated with most of the REEs. A three-dimensional tracer system was established via Gdanth, NO3−/Na+ and Cl−/Na+ to characterize the impact of sewage treatment plants, hospitals and agricultural activities on river water. The results indicate that with the acceleration of urbanization, abnormal REEs can be considered as a sensitive indicator to assess the influence of anthropogenic activities on water ecosystems.

All is said in favor of this: the real practice of the Middle East States as far as is concerned foreign policy adjusting to the new realities and in vital interest of their own, having been proamericanly imbalanced during long period. This process is not simple: during it diff erent changes are quite possible even retreats to the previous stands. Mush is dependent on the force of Washington counteraction and of course dependent on political will and fi rmness of purpose of ruling circles of the Arab States in the Middle East. But most important is that the fi rst steps are already have made, fi rst of all in energy security. All of this is in favour of Russia, vitally interest in such world architecture of the global policy which is to work for majority of States on the Earth and be more justice. As far as the current situation is concerned Arad States of the Middle East even nowadays might be cold supportive partners of our country. Beside energy background of this partnership are ethics, social and confessional values, first of all in family relations and gender sphere. The most common factor, which gets as closer is our long non conflict multi centuries history of the mutual intercourse: we never fought each other under battle ground. On the contrary there are a lot of examples of our beneficial cooperation in economy, investment activity, medicine and so on and so forth, and in recent years — common struggle against national terrorism.
Diplomacy in a Proxy war

Published: February 2023

The activity of diplomacy to resolve the proxy war as one of the military conflicts of our time, which, apparently, will signifi cantly determine the development of the military-power component of foreign policy for many years, is based on the principle of interaction and interdependence of several participants in the military proxy confl ict. The confl icting interests of the participants require flexibility, insight, and the ability of diplomacy to bring together and promptly analyze the totality of conflict factors based on reliable, proactive information. In the conditions of the existence of nuclear weapons, the concept of "proxy war or proxy war" largely determines the relations between states in the foreign policy sphere. The efforts of politicians, diplomats and the military in the preparation and during the proxy conflict are characterized by a two-vector orientation: firstly, to achieve the goals set, and secondly, to prevent the transformation of a military-military clash into a large-scale.
China's view of a multipolar world
Authors:   Diplomatic Academy of the Ministry of Foreign Aff airs of Russia, Moscow, Galimzyanova A. K.
Published: February 2023

The article examines the position and attitude of China to the multipolar world. The author emphasizes that a profound transformation of the entire system of international relations is currently taking place. World has entered a new period of upheaval and change. There are more and more global challenges and threats. Tendencies of unilateralism, protectionism and hegemonism are increasingly manifesting themselves. Non-traditional security threats such as public health, terrorism, climate change and cybersecurity are also on the rise. The instability and uncertainty the world is facing is obvious. At the same time, the world’s multipolarity, economic globalization, social informatization and the diversification of civilizations continue to deepen, and the international community’s call for peace and development is growing stronger. Further, the author reveals in detail the position of China on how to respond to new challenges and changes taking place in the world, set out by the Minister of Foreign Affairs of the People’s Republic of China, Wang Yi, who calls for peace-loving, striving for development and openness, cooperating with each other and not confronting and uniting. He also calls to be fair, not to intimidate anyone and not to engage in harassment. Much attention is given to the presentation of the views of Chinese researchers on the modern world order and on the role of China in international relations. Some scholars argue about the need to continuously increase the level of openness to the outside world through the joint construction of the “Belt and Road” and the deepening of strategic cooperation with developing countries. Others speak of the need to adhere to the democratization of international relations, oppose hegemonic powers and advocate for joint overcoming of global challenges and threats. Still others are about maintaining strategic resolve, promoting economic globalization and improving people’s living standards. The author comes to the conclusion that China is an active supporter of a multipolar world and is ready, together with other countries, to strengthen unity and cooperation, continue to improve the global governance system and jointly seek ways to solve global problems.

Published: February 2023

Intersphincteric resection (ISR) with coloanal anastomosis is an oncologically safe anus-preserving technique for very low-lying rectal cancers. Most studies focused on oncological and functional outcomes of ISR with very few evaluating long-term postoperative anorectal complications. Full-thickness prolapse of the neorectum is a relatively rare complication. This report presents the case of a 70-year-old woman presenting with full-thickness prolapse of the side limb of the side-to-end coloanal anastomosis occurring 2 weeks after the stoma closure and 2 months after a robotic partial ISR performed with the Da Vinci single-port platform. The anastomosis was revised through resection of the side limb and conversion of the side-to-end anastomosis into an end-to-end handsewn anastomosis with interrupted stitches. This study describes the first case of full-thickness prolapse of the side limb of the side-to-end handsewn coloanal anastomosis following ISR. Moreover, a revision of all reported cases of post-ISR full-thickness and mucosal prolapse was performed.

The article discusses the main directions of increasing the efficiency of agricultural production. At the same time, a change in the methodology of payroll is proposed as a priority, since it is the most important source that characterizes the welfare of the vast majority of the population of the Russian Federation. Studies on the formation of wages, as well as its significant differentiation, are the most important component in determining the welfare and solvency of the country's population. We have revealed that the efficiency of agricultural production largely depends on the material motivation of employees. The proposed methodology is based on the transformation of the current labor participation coefficient.
Time and Timelessness in Greek Afterlives
Authors: Burton Diana
Published: February 2023

Greek constructions of the afterlife are characterized by the absence or perversion of conventional markers of time among the living. Whereas the living measure time by changes in the seasons and in themselves – within the narrative of their lives – the dead, like the gods, are characterized by their immunity to change. In the underworld of the Odyssey, eternity is defined by cyclical and repetitive tasks or else simply by monotony, since there is not even day or night. Even in the Isles of the Blest, where day and night may exist, an absence of seasons results in a landscape of timelessness. The isolation of the dead is emphasized through their lack of awareness of the passing of living time. The pattern may be disrupted by the arrival of living visitors, whose narrative may briefly involve the dead, and thereby give them a fleeting awareness of time.
The influence of public opinion on the socio-political life of society
Authors:   Mariupol State University, Sliushchynskyi Bohdan
Published: February 2023

Different countries around the world have different attitudes to the problem of public opinion. If we analyze these views, we can see that about 50% of the world's population believes that public opinion does not exist and can not exist, but the other 50% believe that it still exists. Of course, as the life of society demonstrates, public opinion exists in democracies and cannot exist in totalitarian countries where there is "one true opinion." Ukraine became a democratic country today, one of the European states, that has the rich ceremonies, traditions, habits, language, special culture, belief and desire of independence and social economic development, and yet political understanding. It is native desires of the Ukrainian people. The aim of the article are generalization of theoretical approaches in relation to a concept "public opinion" and attempt to analyze her influence on socio-political life of country. A few directions of research of public opinion were formulated in the modern world. The Ukrainian scientists try revaluation essence of public opinion, interpret it from positions of modern sociological knowledge, in fact at past tenses this theme was closed. Today the sociologists of Ukraine try to investigate the role of public opinion for an association, to show her value as social institution and to define ways and principles of her forming and functioning. Such known Ukrainian scientists worked in the field of public opinion and politics. Public opinion is the phenomenon historical. Social, economic, political, ideological his operating conditions change on the measure of development of civilization, human society, his functions become complicated, a role and status change in life of society. To Tom, taking into account general meaningfulness of public opinion simultaneously the looks of scientists changed to her function directly in the administrative department of society, political process. In the process of forming of public opinion certain intercommunications are distinguished between his transmitters. Interests of society on the whole cannot coincide with interests of separate task forces and even layers of population. Therefore for individuals, collectives, groups of population correct public opinion is formed not always, id east that would represent majority of task forces of population opinion. The process of forming of public opinion is multidimensional He is based on specific interests and on differences in knowledge, culture, being informed of people. Forming comes true by exchange opinions during conversations, consultative meeting, discussions, and spores. Thus, it is possible to assert that public opinion ‒ it the phenomenon of mass consciousness of people, she is formed and develops together with development of society, and development of society depends on rights freedoms of citizens, that create this society. And as citizens elect the organs of rule and enter to them, then they influence on socio-political life countries.

The article is devoted to the analysis of the Canadian experience of supporting national culture in response to the challenges of the «pandemic period», the experience of optimizing the resources of available cultural capital to create a system of self-organization of Canadian society in modern realities. For the whole Ukrainian society, as well as for the theory and practice of domestic culturological knowledge, to optimize cultural policy it is necessary to investigate and understand universal and specific steps in the management of cultural and artistic spheres of other countries, the resources of cultural capital, Article is focused on the process of conceptualization of the experimental knowledge gained in recent management of Canada's national culture which took place in a short period of the first pandemic challenges in parallel with the rapid instrumentalization of the results (approaches, analytical and interpretive systems, management models). It is noted that the Canadian experience of providing flexibility in the movement of managerial, financial and organizational resources, which would be optimally correlated with the dynamics of modern socio-cultural life, is extremely valuable. The existing model of cultural governance in Canada, the organization of interaction between the state and cultural institutions - «the arms-length principle» in modern realities allows to flexibly and dynamically respond to the variability of socio-cultural situation. The policy of multiethnic multicultural Canada has for many decades been pursued in the field of culture in the context of affirmation of national cultural identity and cultural sovereignty. The article analyzes ways and means to strengthen the support of Canadian content at the international level and stimulate the development of the domestic market of creative industries, artists support, creative professions, cultural management sector at the national, regional and local levels in recent years. The research is focused on the Canadian experience of integrating into the organizational culture of management of various creative actors - the state, civil society institutions, artistic communities, organizations and individuals whose activities are directly or indirectly related to cultural and artistic practices.
Women's Legacy in the Bible

Published: February 2023

Every poet and storyteller sing a poem and writes story comparing women to Pushpam, means flower. There are many kinds of flowers, each with different speciality. Their colours and smells are different. Similarly, every woman created by God has different qualities and nature. Even in the Bible, each story portrays women in a different form with different characteristics. But only some flowers attract human attention. Many kind of flowers that grow in the forest bloom and wither, no one is there to take care of it. No one enjoys its beauty, and no one consumes its fragrance. However, God does not refuse to give beauty and fragrance to it. The Lord Jesus Christ tells us to observe how the wild flowers grow. If God takes care of them, will He not take care of humans? Every woman in the scripture’s blossoms like a flow and God uses them for a good purpose. This article explains about the women’s legacy in the Bible

La investigación se realizó con el objetivo de estimar la disponibilidad a pagar (DAP) de los visitantes locales a los servicios recreativos pasivos del mirador natural denominado “Cerrito de Huajsapata” (Puno – Perú) en un hipotético caso de mejora de los servicios. Se siguió un enfoque cuantitativo, a través de la técnica de la encuesta, aplicando el método de valoración contingente a una muestra probabilística de 383 visitantes locales que pertenecen a la población en edad de trabajar (PET). Los resultados demuestran, de acuerdo con el cálculo de la DAP en Soles (S/) que los visitantes locales estarían dispuestos a pagar por acceder a los servicios recreativos mejorados S/1.00, pero si esta tarifa se incrementara en un sol, la DAP tiene una probabilidad de incrementar en 47% ya que un servicio turístico conlleva a las expectativas de mejora de dicho servicio; sin embargo, se debe de tener en cuenta que dicho incremento tiene un límite. Por tanto, hay una predisposición por los visitantes locales a pagar por el acceso a los servicios recreativos del mirador natural del “Cerrito Huajsapata” siempre y cuando estos servicios sean mejorados.
Topology optimization of large ultrasonic tools for uniform vibration using density model
Authors: Wada Yuji , Nakamura Kentaro
Published: February 2023

The uniform vibration of vibrating tools for ultrasonic welding is important for industrial applications but the design requires considerable know-how due to the nature of the wave phenomena. Topology optimization is a structural optimization technique that achieves the desired objective by controlling the material distribution in the design region including voids. In this study, we propose an objective function that maximizes the amplitude of a specific target point in phase with the input. A uniform vibration is obtained by maximizing the point with the smallest amplitude among multiple target points. Optimization is performed using a commonly used density model, resulting in a vibration distribution with an aligned phase on the output surface. In addition, we perform an eigenvalue analysis of the structure by isosurface extraction to study the frequency error and the deterioration in the uniformity of the assumed vibration mode.
Ultrasonic measurement of thickness of carotid arterial wall using its natural longitudinal displacement

The thickness of the carotid arterial wall obtained from B-mode imaging using ultrasonic diagnostic devices is widely used for the diagnosis of atherosclerosis. However, the measurement interval in the lateral direction of the B-mode image depended on the beam interval (>100 μm). Therefore, the B-mode image is discrete in the lateral direction and cannot reflect changes in local and minute thicknesses. A method for measuring the roughness of the luminal surface of the wall was proposed using the displacement of the carotid arterial wall in the lateral direction during one heartbeat. In this method, the lateral measurement interval is much shorter than the beam interval, enabling a smooth measurement of the luminal surface. By simultaneously applying the method to the lumen-intima and medial-adventitia boundaries of the wall, we propose a novel method to measure the local and minute thicknesses of the carotid arterial wall.
