Theoretical analysis and experimental verification of spatial coherence of acoustic cavitation noise from bubble clusters under ultrasonic horn
Authors: Kuroyama Takanobu , Ogasawara Hanako , Mori Kazuyoshi
Published: May 2024

Acoustic cavitation bubbles under ultrasonic horn in water emit acoustic cavitation noise, which consists of spherical shockwaves. This study theoretically derived the spatial coherence of acoustic cavitation noise or, more precisely, the spectral degree of coherence. The acoustic cavitation noise was found to have spatial coherence characteristics similar to the “thermal light” in optics, unlike ultrasound generated by general transducers, which are analogous to “laser” with high coherence. The experiments validated the derived theory and showed that the spectral degree of coherence of the acoustic cavitation noise depends on the product between the distribution width of the shockwave origin, proportional to the horn diameter, and the angle between the hydrophones viewed from the horn. The lower the product gives, the higher the spectral degree of coherence at a higher frequency range.
Data-volume reduction of optical vortex laser absorption spectroscopy by coarse-graining using a quadrant photodiode
Authors: Minagawa Hiroki , Yoshimura Shinji , Terasaka Kenichiro , Aramaki Mitsutoshi
Published: May 2024

We developed optical vortex laser absorption spectroscopy (OVLAS) to measure the transverse flow velocity relative to the probe beam. In our previous OVLAS setups, a camera is used in the measurement system. This approach constrained the time resolution by image data transfer time and required large computational resources due to the considerable amount of image data. In this paper, we discuss the coarse-graining of OVLAS as a method to improve time resolution and reduce computational resources achieved by replacing the camera with a quadrant photodiode (QPD). Measurement image data obtained from a camera was numerically coarse-grained to evaluate the feasibility of measurements using a QPD. Subsequently, the transverse flow velocity was measured by QPD. Measured transverse flow velocity had a mean absolute percentage error of 18%, confirming the practical validity of coarse-graining OVLAS. The data volume required to determine the flow velocity was reduced to 1/120 from the original OVLAS.

Published: May 2024

This study investigates the timing margin required to handle fluctuations and variations in superconductor single-flux-quantum gate-level-pipelined adders; a smaller timing margin would improve the clock frequencies of gate-level-pipelined circuits. To evaluate timing margins, we demonstrated three 4 bit adders with 50-, 75-, and 100 GHz target clock frequencies using a 1.0 μm process. We estimated that the required timing margin of the adders was 2.1 ps. This indicates that previously reported gate-level-pipelined circuits operating at 30–60 GHz could operate at higher clock frequencies by reducing the timing margins.

Published: May 2024

Objective. Study PVY spread at the territories of the regions of Chernihiv and Kyiv. Methods. Laboratory (virological, immunological, electronic microscopy), field, statistical. Results. Data as of 2009–2023 show a significant PVY spread as monoinfection and in combination with other viruses, which carries significant risks for the seed potato production system in the regions of Chernihiv and Kyiv, Ukraine. The share of complex infections with the presence of PVY in affected samples in the region of Chernihiv within the period from 2009 to 2016 grew from 19.4 % to 47.8 %. In 2017, PVY was detected as monoinfection for the first time (4.0 %), after which a rapid increase in the share of PVY as monoinfection was reported over the next seven years to the level of 79.2–84.8 %, and the share of mixed infections with PVY decreased to approximately 13.0 %. A similar pattern of the spread of PVY and complex infections with the presence of PVY on seed potato fields can also be seen in the region of Kyiv, namely: of all analysed samples, the number of samples affected by PVY increases from 3.4–10.9 % in 2015–2016 to 24.8–31.1 % in 2022– 2023. Conclusion. It is shown that over the past 10 to 15 years there has been a rapid spread of PVY and complex infection in seed potato fields — from 15.4 % of all tested samples (including virus-free) to 61.7 %, while the growth from 1.0–5.0 % to 15.4 % took more than thirty years as previously monitored. In the affected samples, the share of infections with the presence of PVY increased from 19.4 to 93.1 % in the region of Chernihiv and varied from 21.8 % to 98.8 %, depending on the year, in the region of Kyiv. This suggests the need for more careful attention to the varietal composition of seed material and the use of only PVY-resistant potato varieties. It has been also shown that the main causative agent of common (rugose) mosaic of the entire spectrum from mild latent with light undulation to acute one with undulation and deformation of the leaf plate is PVY and its complex infections (mainly PVY + PVM), which requires changes to the regulatory documents certifying seed potato fields.
TitleStudy on local practice and effect of traditional filial son story teaching function: Taking Yiwu County as the center
Authors:   The Society For Chinese Humanities In Korea, Guo Ya-jing , Huang Yue-ming , Zhang Ning , Kim Chang Gyeong
Published: May 2024

The Confucian filial piety culture is a very practical culture. How the ancient Chinese government propagates the filial piety culture is an important issue in the study of its inheritance. This paper chooses ancient Yiwu County as a case study to investigate the local government's practice of using traditional filial piety stories, such as filial piety stories or filial piety records, and the effect of practice. In ancient times, Yiwu County used Yan Wu Xiaode's story to carry out local missionary education in two ways: one is to influence local scholars through standardized and grand sacrificial ceremonies, and then pass it on to the people in the county; First, from the central court to the local officials, the main role is to worship Yan Xiaozi, the model of filial piety, which affects the value orientation of the people. In Yiwu, where Confucianism is developed, the filial piety culture of local governments has received good feedback, and the filial piety culture has also penetrated into the blood of scholars. In the context of the Chinese subject culture of “loyalty and filial piety”, it also provided the “loyalty and justice” dividend for the ancient Chinese feudal government, and a large number of “loyal and patriotic” scholar-officials emerged.
The Shift and Repositioning of Spatial Narratives Surrounding Impoverished Chinese Youth: A Study on the Evolution and Recontextualization of Their Living Conditions
Authors:   The Society For Chinese Humanities In Korea, Lee Bogo
Published: May 2024

This research examines how impoverished youth's perceptions of space, both real dwelling spaces and abstract social progress areas, are evolving. It examines in particular how the problems of'snail homes' and 'ant tribes', which were big difficulties connected to living spaces in the early 2010s, are continuing in what social context, and how disadvantaged youth are generating new narratives within this. They deploy narratives of 'disgust and exclusion' and'sympathy and empathy' towards poverty at the same time, eventually demonstrating new attitudes and actions in reaction to the state's narrative that has backed the development logic. Of course, their living conditions have not changed significantly, but the young are now learning to collect and recontextualize their own experiences and narratives in limited living spaces. Furthermore, in terms of social progress, they choose employment that provide stability in their lives rather than a single direction of travel focused in the city or the quest of tremendous achievement. Even people with strong academic credentials opt to go to the competitive perimeter, advance their jobs, and then return to the core city. The author believes that their psychological state is not entirely free of the stress of a competitive society and the narrative of competition, but that they are becoming psychologically stronger through lightness rather than previous heaviness, and cynicism and joy rather than sadness or despair. When reading impoverished youth's actions as signals of social transformation, it is assumed that the spectrum of interpretations will expand as we approach closer to future China.

Published: May 2024

As digital ecosystems evolve into increasingly complex networks,
harnessing their collective potential becomes paramount. This article
focuses on developing software for smart ecosystems by programming their
underlying System-of-Systems (SoS)—a domain ripe with opportunities
and challenges. We propose the Holon Programming Model (HPM), which adds
the programmability aspect to the holonic architecture of SoS and will
pave the way for more integrated and adaptable systems. Demonstrating
the HPM’s utility, we show how developers can program diverse behaviours
and execute operations within the disaster management ecosystem, aiming
to inspire and motivate software developers to explore the potential of
SoS-level applications, which are fundamental for smart ecosystems.

Motion Planning by a Two-Degree-of-Freedom Driving Simulator for Optimal Generation of Acceleration Sensation
Authors: Safaei Erfan Akhavan , Sorbi Iman , Hosseini Ali Reza , Honarvar Mohammad Hadi
Published: May 2024

This research focuses on inducing the perception of acceleration in the occupant in accordance with a given motion for the vehicle. For a desired driving experience without using a highdegree-of-freedom and expensive mechanism, without the actual presence of the occupant in the moving vehicle, the presence of the occupant in a two-degree-of-freedom simulator creates the perception of being in that motion. Human perception of motion is created through the measurement of various physical parameters, primarily vision, acceleration, and sound, and by different receivers. This research targets only the vestibular acceleration sensor, as the most important acceleration sensor in the human body, to induce the desired sensation and, due to the lower degrees of freedom of the mechanism compared to the actual motion, the simulator motion in the presence of various limitations is optimally planned and discussed based on the closest motion sensation to the desired motion in two horizontal and vertical directions.
A Conditional Invertible Neural Network-based Fault Detection
Authors: Sun Wenxin , Shi Xudong , Xiong Weili , Chen Hongtian , Huang Biao
Published: May 2024

Residual generation and hypothesis test are two important components in
fault detection techniques. Recent studies mainly focused on enhancing
residual generation algorithms, but often overlook the Gaussian
distribution assumption that necessary for hypothesis test. Based on the
conditional invertible neural network (CINN), this study proposes a
novel approach for mapping residual signals into near-Gaussian
distributed latent variables, thereby enhancing the reliability and
effectiveness of the hypothesis test approaches used for fault
detection. With the specially designed architecture using CINN, the
proposed mapping from residual signals to latent variables has no
information loss, thus guaranteeing the accuracy of the proposed fault
detection method. The main contributions of this study are two-fold: 1)
To ensure that the latent variables are distributed similarly to an
ideal Gaussian distribution, a novel CINN training approach is proposed;
2) historical process information is incorporated into the
residual-to-latent variable mapping, dynamically refining the mapping
procedures in response to the system behavior. This approach is
primarily used to tackle the challenges posed by non-additive and
non-Gaussian noises in industrial systems. A DC speed control system and
a waste water treatment system are adopted to verify the effectiveness
of the proposed fault detection approach.

Published: May 2024

In recent years, the robotics field has witnessed an unprecedented surge in the development of humanoid robots, which bear an increasingly close resemblance to human beings in appearance and functionality. This evolution has presented researchers with complex challenges, particularly in the domain of controlling the increasing number of robotic motors that animate these lifelike figures. This paper focuses on a novel approach to managing the intricate facial expressions of a humanoid face endowed with 22 degrees of freedom. We introduce a groundbreaking inverse kinematic model that leverages deep learning regression techniques to bridge the gap between the visual representation of human facial expressions and the corresponding servo motor configurations required to replicate these expressions. By mapping image space to servo motor space, our model enables precise, dynamic control over facial expressions, enhancing the robot’s ability to engage in more nuanced and human-like interactions. Our methodology not only addresses the technical complexities associated with the fine-tuned control of facial motor servos but also contributes to the broader discourse on improving humanoid robots’ social adaptability and interaction capabilities. Through extensive experimentation and validation, we demonstrate the efficacy and robustness of our approach, marking a significant advancement in humanoid robotics control systems.

Traumatic rupture of the right diaphragmatic dome with herniation of the liver into the thorax is a rare lesion. It is often part of a polytrauma, for which it is a criterion of severity. Whether early or late, it exposes the patient to cardiopulmonary complications due to compression. Right diaphragmatic rupture is difficult to diagnose. Its clinical signs are not very specific, and imaging can be misleading, as it visualizes the ascending organs but not the rupture itself. The thoracic approach is often preferred because of the difficulty of exposing the diaphragm in the presence of the liver. We report a case of right diaphragmatic rupture with total passage of the liver into the thorax following an MVA in a polytrauma patient.

Purpose: The aim of the study was to evaluate the application of the WHO syndromic STI management strategy. Patients and methods: We carried out a prospective, descriptive study of patients admitted to our hospital. For presumed bacterial STIs at the urology department of CHU Gabriel TOURE from February 2017 to May 2018. HIV cases were not included. Results: We obtained the following results: 100 STI cases (Dysuria, Cystitis, Scrotal swelling, Prostatitis). The sex ratio was 88% in favor of males. The 26-35 age group was the most affected, with married patients the most represented. All cases were clinically diagnosed, and further investigations were requested to confirm the diagnosis. In terms of syndromic management, probabilistic antibiotic therapy was applied to each type of STI, and the antibiotic therapy was readapted. Treatment was adapted to the antibiogram. Overall, 88.28% of all patients were cured. Conclusion: The WHO proposes syndromic management of STIs in countries where laboratory diagnosis is not possible due to doubtful results, insufficient human resources or obsolete equipment.

Published: May 2024

Uncompensated loss of teeth leads to an occlusal disorder that cause functional and esthetic damage. These disturbances include the egression of opposing teeth, resulting in a reduction of the available prosthetic space. The management of these complications requires a meticulous analysis, which is materialized by the prosthetic project that visualizes the final result of the rehabilitation. The fixed prosthesis seems to be an interesting therapeutic option to restore the disturbed occlusion plane. Preparation guided by the prospective model is essential to create the necessary space for the future prosthesis. This article describes a clinical case of managing limited prosthetic space using fixed restoration.

Introduction: Tuberculosis is an infectious disease that can affect different organs. The spinal disorder is called tuberculous spondylodiscitis (Pott's disease). The objective: Was to elucidate the aspects taken into account by caregivers in the diagnosis of tuberculosis spondylodiscitis in patients referred to the reference health center of commune III of Bamako for anti-tuberculosis treatment. Methodology: This was a descriptive, retrospective study covering all patients referred to CSRef CIII from different health structures with the diagnosis of Pott's disease for treatment during the study period. Results: During the study period, we collected 156 patients. The male sex represented 54% with a sex ratio of 1.18. The average age was 39.3 years with extremes of 12 and 92 years. All patients presented with spinal pain, fever was present in 11.11% of patients and 2.7% had respiratory symptoms. Tuberculin IDR was positive in 95.8% and 2 patients were AFB sputum positive. X-ray (of the lumbar spine) was negative in 18%; there were images of degenerative lesions in 41.6% and only 40.2% of patients had presumptive radiological signs. CT was carried out in all patients revealing 33.33% of sequelae of fractures and degenerative lesions and 55.55% of presumptive signs of tuberculous spondylodiscitis. Only 41.66 of the cases were referred by specialist doctors. Conclusion: In our context, the diagnosis of Pott's disease seems to be based mainly on chronic spinal pain and positive IDR and is not often made by appropriate personnel.

Introduction: Klippel-Trénaunay syndrome is a rare congenital vascular disorder characterized by a triad of cutaneous capillary malformations, varicosities and hypertrophy of soft tissues and overgrowth bones. Among the cutaneous malformations are angiokeratomas, which appear as a papule from 2 to 10 mm in diameter, usually dark red in color, although they may be blue or black, and their surface is keratotic on palpation. Angiokeratomas pose a therapeutic challenge, especially in cases of multiple or extensive lesions. Laser modalities have demonstrated efficacy and may be successful treatment options. Clinical Case: A 13-year-old male patient with a clinical history of Klippel-Trénaunay syndrome diagnosed at birth. He came to the outpatient services because he presented dermal nodular lesions at the inguinal region, painful on palpation, with a duration of one week. In addition, he had an increase in diameter of the left lower limb with multiple varicose veins, ochre dermatitis on the inner side of his left leg. On the right lower limb there are violaceous patches with the presence of euchromic papules grouped together, of hard consistency at the left knee region. He also presents multiple violaceous keratotic papules on the scrotum, thigh and left knee bleeding on manipulation and trauma. Skin excision was performed in the right inguinal region for biopsy, which reported macroscopically fibrous, multinodular element measuring 0.7x0.5x0.3cm, whitish surface of firm consistency and whitish heterogeneous surface upon sectioning. Microscopic inspection was carried out with hematoxylin and eosin technique, which reported skin with epidermis showing acanthosis, hyperkeratosis, papillary dermis with congestive dilated vessels, negative for malignancy and compatible with angiokeratoma. Among the treatment options, it was decided to initiate CO2 laser therapy with satisfactory results. Conclusions: Klippel-Trénaunay syndrome is an extremely rare vascular pathology ........

Establishing correlation between teeth exposure to mechanical loads during orthodontic treatment and occurrence of denticles in teeth
Authors: Osipova V. A. , Zubkova N. V. , Kolyada A. A.
Published: May 2024

INTRODUCTION. Treatment with braces can correct pathologies of the bite, temporomandibular joint, and improve the facial and smile aesthetics. However, along with the positive effects of braces, there are a number of negative effects, one of which is the formation of denticles caused by mechanical stress during orthodontic treatment. Understanding not only the advantages, but also the disadvantages of braces systems can minimize the negative effects of treatment with non-removable orthodontic appliances by means of modern technologies.

AIM. Establishing the effects of mechanical forces applied to the tooth during orthodontic treatment with braces on the formation and growth of denticles.

MATERIALS AND METHODS. 41 cone-beam computed tomograms (CBCTs) of patients aged 11 to 59 years, randomly selected, treated with non-removable orthodontic appliances for two years were studied. A total of 90 teeth were found in which pulp denticles formed primarily or grew in size. CBCT was analyzed in Planmeca Romexis Review software before and 2 years after orthodontic treatment. Findings were recognized as statistically significant at p < 0.05.

RESULTS. The formation and development of denticles after wearing orthodontic appliances was observed in 87.2 % (n = 30) of cases). Primary denticle formation occurred in 46.2 % (n = 18) of cases, and an increase in denticle size was observed in 25.6 % (n = 10) of cases.

CONCLUSIONS. The obtained statistical data supports the relationship between the effects of mechanical stress on teeth during orthodontic treatment and denticle formation.

Economic losses in the system of ensuring the economic security of an economic entity and the State
Authors: Grachev Aleksandr , Litvinenko Aleksandr
Published: May 2024

The article presents an analysis of the losses of the economic system under the influence of threats to economic security. It is concluded that the absence of economic losses cannot be considered as a characteristic of the security of the state of the economic system. It is proposed to divide the economic losses caused by threats and dangers, it is necessary to divide them into: those related to countering the threat to economic security; those related to damage from exposure to the threat. The economic losses associated with countering the threat to economic security are divided into: losses necessary to contain the threat at the lowest possible level for existing socio-economic and political conditions, and losses exceeding the amount necessary

Financing of industrial parks
Authors: Kuznecova Svetlana , Kuznetsov Viktor
Published: May 2024

In the article, the authors address the issue of financing industrial parks. The authors of the article point out the need to provide subsidies for the creation of technology and industrial parks only to regions with a low level of socio-economic development, with mandatory private co-financing. The authors indicate that industrial parks, within the framework of the provided federal budget funds, will receive funding from 11 constituent entities of the Russian Federation for the creation of 14 parks for a total amount of 5,7 billion rubles. The purpose of the study is to provide ready-made infrastructure, which is a way to stimulate the development of new industrial projects. The article discusses the experience of the creators of industrial infrastructure.
The authors consider five projects that took the top positions in the funding ranking: Kurgan region (industrial park “Stalmontazh”), Republic of Karelia (technopark “Onezhsky”), Republic of Khakassia (industrial park “Tasheba”), Novgorod region (industrial technology park “Transvit”), Altai Territory (industrial technology park “Component”). As a result of the implementation of the event, it is planned to create at least 20 industrial parks and technology parks by 2024, which will accommodate at least 150 residents and create 1,5 thousand jobs. The volume of investments of management companies in the implementation of new projects in 2023–2024 will be at least 3 billion rubles. The newly created areas of these parks accommodate at least 680 residents, who have created more than 9 thousand jobs. The article discusses an example of launching production using the example of industrial parks in the Nizhny Novgorod region. The implementation of the group’s strategy continues to develop industrial competence centers specializing in the localization of key technological solutions. For the Sollers and UAZ model range, localization of power units will ensure increased competitiveness and increased production volumes.
Does Cash Holding, Intellectual Capital, Gender Diversity of the Board of Directors Affect Firm Value?
Authors: Anggraini Aulia Kus , Lestari Tri Utami
Published: May 2024

The purpose of this research was to determine the relationship between firm valuend cash holdings, intellectual capital, and gender diversity on the board of directors. Companies in the non-cyclical consumer sector that are listed on the Indonesia Stock Exchange (IDX) for the years 2017 through 2021 make up the study's population. Purposive sampling was utilised in the sample selection for this research, resulting in the collection of 18 firms with five years and 90 data observations. The findings of hypothesis testing reveal that firm value is influenced by cash holdings, intellectual capital, and the gender diversity of the board of directors. A favourable impact on firm value is partially provided by intellectual capital and the gender diversity of the board of directors. Cash Holding has little impact on a firm value, though. Future researchers is suggested to reexamine the cash holding variable based on the research findings since the variable in this study had no impact on firm value.

Authors: Febriana Ade Tia , Armansyah Rohmad Fuad
Published: May 2024

There are several factors that influence investment decision making, one of which is the psychology of the millennial generation in Surabaya in making investment decisions. The basis for making investment decisions consists of rate of return, risk and time period. Investment decisions are steps taken by individuals to place their funds in the hope of obtaining a rate of return in the future. This cannot be separated from the influence of financial literacy, financial inclusion and accounting mentality. This research aims to analyze the influence of financial literacy, financial inclusion and mental accounting on investment decisions of the millennial generation in Surabaya. This research method uses quantitative methods. The instrument used was a questionnaire.

Amamentar é um ato muito especial, pois o contato íntimo faz com que mãe e filho se descubram e iniciem um grande vínculo de amor. Assim, durante muito tempo, a alimentação dos bebês foi baseada no princípio da amamentação no seio das suas mães, o que representava uma forma natural e tida como única de alimentar as crianças nos seus primeiros meses de vida, no entanto, com o advento da Revolução Industrial, a prática do aleitamento materno exclusivo foi se tornando mais escassa, principalmente por conta da incorporação da mulher ao mercado de trabalho, tem-se com isso a introdução de novos alimentos para repor o leite materno e assim alimentar os seus filhos. O referido estudo traz um impacto positivo no tocante à conscientização sobre a importância do aleitamento materno e da contribuição para o conhecimento das gestantes acerca da sua essencialidade e dos benefícios que esta prática traz para si e para seus filhos. O presente estudo caracteriza-se por ser um trabalho de cunho científico com metodologia descritiva e foco no método quanti-qualitativo no qual pretendeu-se esclarecer sobre os fatores e as motivações que influenciam a escolha da via de parto e suas consequências. Tem como objetivo geral analisar o conhecimento das gestantes acerca do aleitamento materno na Unidade Básica de Saúde do bairro Setúbal no município de Bacabal – MA e objetivos específicos conceituar o aleitamento materno e a sua importância; destacar as vantagens do aleitamento materno para as mães e bebês e discutir à luz da literatura as informações coletadas com as gestantes na UBS do bairro Setúbal sobre o conhecimento das gestantes acerca do aleitamento materno. Ao término deste tem-se que a prática do aleitamento materno só traz benefícios aos bebês e às mães. É um grande aliado contra diversas doenças e é facilmente digerido e absorvido. Contêm nutrientes e enzimas perfeitamente balanceadas, com substâncias imunológicas que protegem o bebê e provêm tudo o que a criança necessita no início de sua vida. Quanto à pesquisa de campo com as gestantes da UBS do bairro Setúbal em Bacabal – MA, conclui-se que o conhecimento das gestantes entrevistadas não pode ser considerado como pouco, mas que ainda carece de meios para que as mesmas possam ter mais contato com informações sobre a importância da prática da amamentação através de ações da equipe de Enfermagem, mas principalmente dos Enfermeiros que são os responsáveis pelas consultas de pré-natal juntamente com a equipe multidisciplinar.
