Differential interference with actin-binding protein function by acute Cytochalasin B.

Dynamic actin filament remodeling is crucial for a plethora of fundamental cell biological processes, ranging from cell division and migration to cell communication, intracellular trafficking or tissue development. Cytochalasin B and -D are fungal secondary metabolites frequently used for interference with such processes. Although generally assumed to block actin filament polymerization at their rapidly growing barbed ends and compete with regulators at these sites, our molecular understanding of their precise effects in dynamic actin structures is scarce. Here we combine live cell imaging and analysis of fluorescent actin-binding protein dynamics with acute treatment of lamellipodia in migrating cells with cytochalasin B. Our results show that in spite of an abrupt halt of lamellipodium protrusion, cytochalasin B affects various actin filament barbed end-binding proteins in a differential fashion. Cytochalasin B enhances instead of diminishes the accumulation of prominent barbed end-binding factors such as Ena/VASP family proteins and heterodimeric capping protein (CP) in the lamellipodium. Similar results were obtained with cytochalasin D. All these effects are highly specific, as cytochalasin-induced VASP accumulation requires the presence of CP, but not vice versa , and coincides with abrogation of both actin and VASP turnover. Cytochalasin B can also increase apparent barbed end interactions with the actin-binding β-tentacle of CP and partially mimic its Arp2/3 complex-promoting activity in the lamellipodium. In conclusion, our results reveal a new spectrum of cytochalasin activities on barbed end-binding factors, with important implications for the interpretation of their effects on dynamic actin structures.

Zinc finger protein LjRSDL regulates arbuscule degeneration of arbuscular mycorrhizal fungi in Lotus japonicus.

In arbuscular mycorrhizal (AM) symbiosis, appropriate regulation of the formation, maintenance, and degeneration of the arbuscule are essential for plants and fungi. In this study, we identified a Cysteine-2/Histidine-2 zinc finger protein (C2H2-ZFP)-encoding gene in Lotus japonicus named Regulator of Symbiosome Differentiation-Like (LjRSDL) that is required for arbuscule degeneration. Evolutionary analysis showed that homologs of LjRSDL exist in mycorrhizal flowering plants. We obtained ProLjRSDL::GUS transgenic hairy roots and showed that LjRSDL was strongly upregulated upon AM colonization, particularly at 18 days post AM fungi inoculation and specifically expressed in arbuscular-containing cells. The mycorrhization rate increased in the ljrsdl mutant but decreased in LjRSDL overexpressed L. japonicus. Interestingly, we observed higher proportions of large arbuscule in the ljrsdl mutant but lower proportions of larger arbuscule in LjRSDL overexpressing plants. Transcriptome analyses indicated that genes involved in arbuscule degeneration were significantly changed upon the dysregulation of LjRSDL and that LjRSDL-dependent regulation in AM symbiosis is mainly via the hormone signal transduction pathway. LjRSDL, therefore, represents a C2H2-ZFP that negatively regulates AM symbiosis. Our study provides insight into understanding plant-AM fungal communication and AM symbiosis development.

Socioeconomic Deprivation Detrimentally Influences Language Outcomes in Toddlers With Cleft Palate.

The purpose of this study was to examine the influence of socioeconomic deprivation on language and developmental outcomes in toddlers with cleft palate with or without cleft lip (CP ± L). Other factors known to influence language outcomes were also considered, including home language history, history of hearing problems, syndromic diagnoses, and sex. A multicenter, cross-sectional study design was conducted. Data for 566 16-month-old toddlers with CP ± L were collected from 17 outpatient cleft palate clinics located throughout the United States. Outcome measures included the MacArthur-Bates Communicative Development Inventories, LENA Developmental Snapshot, age at first word as reported by the caregiver, and the Ages and Stages Questionnaires-Third Edition (ASQ-3). Multivariable linear or logistic regression was used to determine the influence of socioeconomic deprivation, as measured by the Area Deprivation Index, on language and developmental outcomes. Greater socioeconomic deprivation significantly predicted poorer language outcomes in toddlers with CP ± L, including receptive vocabulary words (p = .02), expressive vocabulary words (p = .02), and late-developing gestures (p = .02). Additionally, toddlers from less affluent neighborhoods produced their first words significantly later than their counterparts living in more affluent areas (p < .01). Lower maternal education levels predicted significantly increased risk for problem solving delays (p < .01), and patients with subsidized insurance were at significantly increased risk for personal-social delays on the ASQ-3 (p < .01). Children with CP ± L are susceptible to developmental delays associated with socioeconomic deprivation. These findings have implications for identifying a child's individual risk factors for developmental language disorders when conducting speech-language assessments. Future study should examine how inequities in care can be mitigated and addressed.

The Scale of Application of Electronic Documentary Communications as the Most Important Indicator for Assessing the Digitalization of Judicial Activities

The only way to speed up and ensure the quality of transmission and receipt of information between courts, participants in legal proceedings, bodies of the Judicial Department system and other entities is the use of modern information technologies. The system-structural, cultural, historical, sociological, statistical methods of scientific knowledge contributed to the implementation of the research objectives. The author defines the differences between the concepts of “documented information” and “documented communications”. The factors influencing the development of electronic documentary communications in the activities of courts have been established. Improving regulatory support is the leading of these factors. At the same time, interaction with the Federal Archival Agency in matters of creating legislation on office work in the Russian Federation was identified as a promising direction. Standardization and simplification of departmental normative regulation in modern conditions can be carried out by creating a single instruction for courts of general jurisdiction on judicial workflow, which should have a high degree of operational electronic component, taking into account the procedural features of the activities of various courts. Based on the proven experience of pilot courts and the use of available resources of the State Autonomous System “Pravosudie”, it seems appropriate to create a permanent system for monitoring the work of the apparatus of the courts in connection with the conduct of electronic documentary communications. The authorized federal subject, the Judicial Department, is entitled to administer this system. As a result of the study, the scientific basis for the practical implementation of the idea of replacing paper judicial documentary communications with electronic ones is determined – this is the cumulation of knowledge and methods of various knowledge systems – jurisprudence, information technology, document science and archival science.

The global approaches to the regulation of quantum communication

In the rapidly evolving field of quantum communication, the regulatory framework plays a crucial role in ensuring security, standardization, and international cooperation. This article examines various approaches employed by countries to regulate quantum communication. The purpose of this research is to comprehensively analyze and compare different international approaches to the regulation of quantum communication to identify key features characteristic of the current stage of development and regulation of quantum communication, as well as to develop recommendations for optimizing and improving regulatory governance in this area. The methodological basis of the study consisted of general scientific and special methods. A detailed study of various legal documents, strategies, and standards related to quantum communication was conducted using the following general scientific methods: analysis, synthesis, induction, and system analysis. Among the special legal methods used was the comparative legal method, which made it possible to identify general trends, differences, and unique approaches in the regulation of quantum communication, as well as the formal-legal method for studying legal categories and legislative techniques used in various acts in the studied area. The study systematically examines legislative measures, government policies, and industry standards to determine the relationship between technological innovation and regulatory governance in the field of quantum communication. The research revealed that the regulation of quantum communication is primarily carried out at the level of strategic documents, such as national roadmaps, which contain recommendations and guidelines for regulating quantum communication. It was found that technical standards play a vital role in the development of quantum communication, with this development occurring at both national and international levels. Special groups and centers have been established for the effective implementation, development, and regulation of quantum communication, which allows for the identification of social, legal, political, and ethical issues. The main conclusions include the need to monitor administrative barriers, identify priority sectors for the implementation of quantum communication, and recognize quantum communication as a dual-use technology. It is recommended that an international certification and tracking system be created for quantum communication devices for export and import control purposes.

Blockchain-Based Spectrum Sharing Algorithm for UAV-Assisted Relay System

Unmanned aerial vehicles (UAVs) are promising tools in mobile communication due to their flexibility. However, the rapid development of mobile communications further intensifies the challenge of spectrum scarcity, necessitating spectrum sharing with other systems. We suggest a Spectrum Sharing Algorithm for a UAV-Assisted Relay System. The utility function of secondary users (SUs) is defined by their communication rate, rewards from relay primary users (PUs), and spectrum leasing expenses. The utility function of PUs consists of their communication rate and revenue from spectrum leasing. We propose a joint optimization algorithm for the positioning and power allocation of UAVs, maximizing the frequency spectrum utilization rate of users. Spectrum trading between PUs and SUs is modeled as a Stackelberg game, and the problem is solved by using Lagrange multipliers and KKT conditions. To enhance the security of spectrum trading, a reputation-based spectrum sharing blockchain consensus algorithm is designed. We utilize Shamir’s secret sharing method to reduce computational complexity. Additionally, we design a smart contract to optimize the functionality of transaction transfers. The findings demonstrate that the proposed algorithm enhances the benefits for both participants in spectrum sharing, while safeguarding the security of spectrum transactions.

Digital Learning Innovation : Language Collaboration In Tanjungmojo Village

This research aims to develop digital learning innovation through language collaboration in Tanjungmojo Village, where low digital literacy and limited access to quality educational resources are the main problems. Limited foreign language skills among village communities are also an obstacle in keeping up with developments in global technology and communication. To overcome this challenge, the research uses an action research approach by involving the active participation of local communities in the development of digital-based foreign language learning programs. This research was conducted in three main stages: (1) analysis of local needs and potential, (2) development and implementation of a language-based digital learning program, and (3) evaluation of the effectiveness of the program. Data was collected through interviews, participant observation, and questionnaires filled out by program participants and the general public. The research results show that the digital learning program developed succeeded in significantly increasing the participants' digital literacy and foreign language skills. In addition, collaboration between local communities and teaching staff creates an inclusive and sustainable learning environment.The main trends identified in this research include increasing community participation, especially teenagers and young adults, in learning activities, as well as increasing interest in continuing to learn and develop new skills through digital platforms. This research also highlights the importance of community support and technology accessibility for the success of learning programs in rural areas. The MIT-18 KKN program in Tanjungmojo Village involved 97 students with learning methods through bilingual digital films and group discussions, which encouraged high participation and involvement. Despite challenges in content retention and technical limitations, this initiative shows great potential in improving education in rural areas and bridging the existing educational gap.

Introducing a self-managed early communication resource for parents – A mixed methods feasibility study of the Swedish “ComAlong online”

Background Web-based programmes offer parents of children with communication difficulties promising access to parent-mediated, early interventions. However, empirical evaluations of such programmes are limited. This study focused on parents and used mixed methods to examine the feasibility of ComAlong online. Methods ComAlong online is a Swedish, self-managed web-resource teaching parents supportive strategies to promote child communication. Data of different types were collected from a total of 71 parents: ten individual parent interviews, 21 pre-questionnaires and 10 post-questionnaires, and finally 50 anonymous digital evaluation surveys. Descriptive statistics and deductive qualitative content analysis were used. Results Findings indicate that parents perceived improved child communication and own competence after using the ComAlong online. The most valued parts included podcasts with experts and videos of parent-child interaction. Parents reported that the resource was easy to use, but they wanted to have gained access to the resource when the child was younger. Suggestions for changes included adding a chat function with experts, a parent net forum, and the possibility of creating personalised playlists of videos and podcasts. Evaluation of the research process revealed difficulties in recruiting parents from local child healthcare services and parents of children not yet with a diagnosis. Conclusions This study supports the potential for self-managed, web-based resources to disseminate evidence-based parent training for supporting early communication development. Importantly, parents lack individual guidance from experts and contact with other parents. Also, measures need to be made to disseminate the resources within local child healthcare services.

Executive function performance in persons with non-syndromic cleft lip and palate

Background: Executive functions (EFs) are crucial cognitive functions that mature from birth to adolescence. They are vital for daily task execution and overall success and also influence language and communication development. Children with EFs deficits often experience delays in language and speech abilities. These impairments are particularly prevalent among individuals with cleft lip and palate. Consequently, speech and language pathologists must address these impairments through assessments and interventions. Despite this urgent need for action, there is a scarcity of research on executive function performance in this population in Thailand, prompting an investigation to address this issue. This study explores executive function performance in this population to enhance the quality of life for individuals with cleft lip and palate. Materials and methods: Using a survey-based approach, executive function performance was assessed in 5- to 15-year-old volunteer with non-syndromic cleft lip and palate attending the speech therapy camp provided by the Princess Sirindhorn IT Foundation Craniofacial Center at Chiang Mai University in April 2024. Parents completed the Behavior Rating Inventory of Executive Function (Parent form), with scores ≥65 indicating executive function difficulties. Results: The study involved 29 participants, 14 males (48.28%) and 15 females (51.72%), with a mean age of 8 years and 9 months. Average scores for executive function abilities in BRI, MI, and GEC were 52.21, 56.48, and 58.90, respectively. There are several participants with abnormal executive function in each age group, along with their average T-scores across different domains. Children aged 5, 6-8, and 9-11 have T-scores for executive function performances falling into problematic levels for 1, 2, and 5 individuals, respectively. Conclusion: Most of the sample group demonstrated executive function skills within the normal range. However, a certain number of individuals experienced issues with executive function. These findings offer guidance for speech and language pathologists and emphasize the importance of executive function in individuals with cleft palates.

Language and communication development and school readiness of children raised by grandparents or in multi-generational homes.

One in ten U.S. children lives with a grandparent, and more foster children are being placed in kinship care. Our objective was to compare early language and communication development and school readiness among children raised by grandparents (alone or in multigenerational households) to children raised by parents. We included in this cross-sectional study children ages 1-5 years from the 2016-2020 National Survey of Children's Health to examine healthy and ready to learn school readiness outcomes and binary language and communication development (2018-2020 data only) by caregiver type (parent, multigenerational, and grandparent-only) with survey-weighted log-binomial regression adjusted for confounders. We stratified by survey years pre-COVID-19 pandemic versus during. Among 33,342 children, 86.0% (SE = 0.51) of children were 'On-Track' for language and communication development; only 37.2% (SE = 0.68) were 'On-Track' overall for school readiness. Children raised by grandparents or in multigenerational households were more often 'On-Track' for school readiness than children raised by parents, but only upon adjustment for covariates (adjusted prevalence ratio (aPR) for grandparent-only 1.13, 95% confidence interval (CI) 1.11, 1.15; aPR for multigenerational 1.13, CI 1.12, 1.15). Smaller and less consistent differences in prevalence were observed for the other outcomes (language and communication development, school readiness domains of early learning skills, social-emotional development, self-regulation development and physical well-being and motor development). A disparity in school readiness may have emerged during the COVID-19 pandemic; children in grandparent-only households had a lower prevalence of being 'On-Track' for school readiness (aPR 0.71, 95% CI 0.69, 0.73) compared to children in parent households, whereas children in multigenerational households continued to be more often school-ready than children in parent households. Large proportions of children across caregiver types were not fully prepared for school. Consideration of key covariates is important because socio-economic disadvantage may mask other advantages grandparent-led and multigenerational households offer children's early development.

Dealing with Overparenting: Developmental Outcomes in Emerging Adults Exposed to Overprotection and Overcontrol

AbstractOverparenting is defined as a parenting style characterized by overprotection, overcontrol, and an excess of involvement in the life of one’s offspring. These types of parenting practices turn out to be particularly intrusive during the period of emerging adults in which the need for autonomy is the element that most characterizes this stage of development. The current review aimed at summarizing studies that considered the repercussions of overparenting’s dysfunctional behaviors on offspring during the developmental phase of emerging adulthood and was carried out using the new Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) protocol. Articles were retrieved from Scopus and Web of Science databases. After having initially considered 832 papers, 31 studies were deemed eligible to be included in this review. The analysis of these studies showed that individuals subjected to overparenting are prone to developing various internalizing and externalizing symptoms. Internalizing symptoms are more prevalent and are often associated with conditions such as depression, social anxiety, and generalized anxiety. Pivotal recommendations have been suggested to reduce the impact of overparenting practices on the well-being of young adults. These include the development of coping strategies and the development of trust, resilience, and open communication within the supportive context of clinical intervention.

Pentingnya Melatih Komunikasi dengan Metode Bermain pada Anak Usia Dini

It is so important to train communication in early childhood. Often children are silent and lazy to do an activity will result in communication skills in children not growing well. In fact, communication skills play an important role in a child's life. Children's good communication skills come from activities that children usually do in their world, namely through playing. However, it is very regrettable if the world for children's play is very sporadic, even difficult to produce. The limited playground for children causes children to be more interested or choose to play inside the house by playing gadgets, watching television although this has several positive impacts, but it makes children no longer interested in playing outside such as playing chase, cats, sobyong and others so that children do not socialize with their peers which can hinder the development of early childhood communication. Therefore, the development of early childhood communication is very important to be developed from an early age. Playing can train children's communication, not only that, but also some aspects of development children.

Bioinspired Functional Composites for Enhanced Thermally Conductivity via Fractal-Growth CuNP Fillers.

Thermal conduction for electronic devices has attracted extensive attention in light of the development of 5G communication. Thermally conductive materials with high thermal conductivity and extensive mechanical flexibility are extremely desirable in practical applications. However, the construction of efficient interconnected conductive pathways and continuous conductive networks is inadequate for either processing or actual usage in existing technologies. In this work, spherical copper nanoparticles (S-CuNPs) and urchin-inspired fractal-growth CuNPs (U-CuNPs), thermally conductive metal fillers induced by ionic liquids, were fabricated successfully through the electrochemical deposition method. Compared to S-CuNPs, the U-CuNPs shows larger specific surface contact area, thus making it easier to build a continuous conductive pathway network in the corresponding U-CuNPs/liquid silicone rubber (LSR) thermally conductive composites. The optimal loading of CuNP fillers was determined by evaluating the rheological performance of the prepolymer and the mechanical properties and thermal conductivity performances of the composites. When the filler loading is 150 phr, the U-CuNPs/LSR produces optimal mechanical properties (e.g., tensile strength and modulus), thermal conductivity (above 1000% improvement compared to pure LSR), and heating/cooling efficiency. The enhanced thermal conductivity of U-CuNPs/LSR was also confirmed through the finite element analysis (FEA) overall temperature distribution, indicating that U-CuNPs with larger specific surface contact areas exhibit more advantages in forming a continuous network in composites than S-CuNPs, making U-CuNPs/LSR a promising and competitive alternative to traditional flexible thermally interface materials.

Psycho-semantic analysis of job advertisements as a communicative tool of educational marketing

Introduction. The relevance of the study of job advertisements for teachers and psychologists is associated with the need to find tools for regulating communication within the modern educational environment with dynamic, constantly changing working conditions. The publication of employer requirements sets the direction for changing the criteria for the success of the specialist, which changes the entire educational environment. The purpose of the study: to identify the categorical semantic structure of job advertisements for teachers (using the example of the "Infrastructure of Scientific Research Data" platform). Materials and methods. The object of the study was a corpus of teacher job vacancies from the "Infrastructure of Scientific Research Data" platform, published in 2023 in 83 regions of Russia (5561 vacancies). The job postings included descriptions of candidate requirements, information about the offered salary, and the region in which the vacancy was available. As a comparison group, a corpus of psychologist job vacancies (2076 vacancies) was considered. The following methods were used in the study: 1) Latent Dirichlet Allocation (LDA) method for identifying and analyzing the structure of requirements presented in teacher and psychologist job vacancies; 2) Term Frequency-Inverse Document Frequency (TF-IDF) method for categorical semantic analysis of the structure of teacher and psychologist job vacancies and description of the semantic framework (frame) of the job description; 3) Descriptive statistical methods for analyzing the needs of professionals in helping professions in different regions of Russia and the conditions offered to them. The results of the study. The regions of the Russian Federation with the greatest need for teachers and psychologists have been identified. Based on the statistical significance in the collection of text documents, the most demanded skills of teachers by employers are identified: methodological development and design of an individual educational route (0.167), work with children with disabilities (0.144), organization of the educational process (0.089). For vacancies of psychologists, the most significant were: work on investigative actions (0.319), methodical work in an educational organization (0.187), psychological and pedagogical support for successful development and training (0.129). The main meanings governing professional pedagogical activity are more focused on meta-skills based on the values of inclusion and continuous improvement of education, as well as on flexible skills (Soft skills) that increase competitiveness in various fields of pedagogical activity. In the vacancies of psychologists, professional skills (Hard skills) are relevant, applicable in specific areas, which somewhat narrows the scope of professional implementation. Conclusion. The results of the empirical study allow for considering job vacancy advertisements as one of the communicative tools of educational marketing. Analyzing the significant professional skills from the employer's perspective will enable the development of recommendations for the development of professional communication for teachers, which can be considered in the system of continuous professional education, as well as in regulating interaction within the educational environment. Automated analysis of job vacancies can become a successful interactive diagnostic tool for educational marketing, necessary for the development of the educational space and the improvement of the competitiveness of educational institutions.

Transformation of Factors and Mechanisms of Involvement of Juveniles in Criminal Activity: Kazakhstan Experience Against the Backdrop of Foreign Practice

Abstract The purpose of the work is to identify factors influencing changes in the criminological portrait of a juvenile offender, features of its changes, as well as modern trends shaping the personality of a juvenile offender. The study gives reason to say that risk factors for involvement in criminal activity as a separate type of criminogenic factors have not undergone radical changes. The work gives reason to assume that with the development of ICT and communication at a distance, influence of the peer group and the role of hierarchy in the juvenile delinquency may be weakened. In addition, there still exist a problem associated with the lack of terminology, methods for assessing the personality of a juvenile cybercriminal, as well as the very definition of the juvenile cybercriminal concept. The results of the study can be used to develop strategies and measures to prevent and combat juvenile delinquency.

Intelligent joint communication and computation scheme of UAV-assisted Offloading in high speed rail scenarios

With the continuous development of communication and computation technologies, large bandwidth services place higher demands on computing capacity and throughput in High-Speed Rail (HSR) scenarios. On the one hand, Millimetre-Wave enables high data transmission rates, but leads to high Doppler frequency deviation as well as large path loss. On the other hand, the development of Mobile Edge Computing greatly alleviates user computing congestion. In this paper, we propose the Adaptive Joint Communication and Computation Resource Allocation scheme to solve the energy optimization problem of a dual-band UAV and Mobile Relay relay-assisted HSR offloading system. This scheme works well to optimize the performance of the system through resource allocation. In addition, since the optimization problem is modeled as a Mixed-Integer Nonlinear Program, we propose the Pre- and Post-state connected Parameterized Deep Q-Network algorithm, which is based on Deep Reinforcement Learning approach, for offloading decision and bandwidth resource allocation. Simulation results show that the proposed algorithms result in lower system energy consumption, while ensuring a high task completion rate as well.
