Structuring Interdigitated Back Contact Solar Cells Using the Enhanced Oxidation Characteristics Under Laser‐Doped Back Surface Field Regions

Interdigitated back contact (IBC) architecture can yield among the highest silicon wafer‐based solar cell conversion efficiencies. Since both polarities are realized on the rear side, there is a definite need for a patterning step. Some of the common patterning techniques involve photolithography, inkjet patterning, and laser ablation. This work introduces a novel patterning technique for structuring the rear side of IBC solar cells using the enhanced oxidation characteristics under the locally laser‐doped n++ back surface field (BSF) regions with high‐phosphorous surface concentrations. Phosphosilicate glass layers deposited via POCl3 diffusion serve as a precursor layer for the formation of local heavily laser‐doped n++ BSF regions. The laser‐doped n++ BSF regions exhibit a 2.6‐fold increase in oxide thickness compared to the nonlaser‐doped n+ BSF regions after undergoing high‐temperature wet thermal oxidation. The utilization of oxide thickness selectivity under laser‐doped and nonlaser‐doped regions serves two purposes in the context of the IBC solar cell, first patterning rear side and second acting as a masking layer for the subsequent boron diffusion. Proof‐of‐concept solar cells are fabricated using this novel patterning technique with a mean conversion efficiency of 20.41%.

Strengthening Workplace Learning in Medical and Health Profession Education: Medical Educators’ Perspective

Abstract The profession of medicine is a challenging one considering the pace with which medical knowledge continues to expand on a daily basis. The purpose of the current review was to explore the significance of workplace learning from the perspective of different stakeholders. An extensive search of all materials related to the topic was carried out on the PubMed and Google Scholar search engines, and a total of 26 articles were selected based on their suitability with the current review objectives. Keywords used in the search include workplace learning and medical education in the title alone only. The workplace offers an opportunity for medical students to apply their acquired knowledge and participate in the process of patient care. Workplace learning gives a platform for medical students to not only participate in patient care but also gradually move forward on the path to becoming an effective member of the health workforce. We must realize that it is not only the students who derive benefits from workplace learning but also the teachers who can optimize their teaching and facilitation skills. To conclude, acknowledging the scope and merits attributed to workplace learning for different stakeholders, there is a definitive need to strengthen the overall process. Medical teachers have a crucial role to play in the strengthening and reinforcement of workplace learning in different contexts, and thus, they should be supported in their task to eventually improve the quality of medical doctors that we are producing.

PROBLEMS OF THE EFFECTIVENESS OF REGULATORY LEGAL ACTS IN THE HEALTHCARE SYSTEM FOR MAINTAINING THE QUALITY OF ACTIVE LONGEVITY IN THE REPUBLIC OF KAZAKHSTAN

The article analyzes the institute of active longevity in the Republic of Kazakhstan, which has been called “antiaging” in science from the point of view of legal regulation of basic socio-economic direc-tions. This covers, first of all, the health care system, social security, social services, etc. The article exam-ines the socio-legal policy of the state on issues of ensuring a fruitful human life expectancy. The authors draw attention to the priority, from their point of view, directions of state policy in the field of regulation of healthy lifestyle issues and ensuring human life expectancy. Special attention is paid to the lack of le-gal regulation of the conceptual category of active longevity and its definitions in Kazakhstan. Attention is drawn to the fact that today in Kazakhstan there is no full-fledged, multidimensional legal framework, in addition, there is a clear need for a clear definition of the object of regulation in the sphere of these legal relations and the differentiation of hierarchy, that is, the levels of regulatory legal regulation. The article notes the need to conduct special research on increasing human life expectancy. The lack of or-ganizational and legislative measures create the main difficulties in the practical implementation of the achievements of medical science in the practical life of the country. The scientific achievements avail-able to medicine to prolong human life and maintain its quality are based primarily on the fight against diseases caused by aging, rather than on intervention in the aging process itself. The author emphasizes the latest achievements of scientists that genetically a person has a complex program to counteract ag-ing. And without a theoretical understanding of the aging process and the identification of technologies to overcome the limit of human life expectancy, the whole complex of biomedical sciences, from the point of view of practice, may not be so effective without direct interaction with other branches of sci-ence and, above all, right-wing science.

Potential for Energy Recovery from Boundary-Layer Ingesting Actuator Disk Propulsion

The theoretical benefits of highly integrated propulsion systems are highlighted herein by assessing the potential for energy recovery utilization using actuator disk propulsion. Decomposing aerodynamic forces into thrust and drag for closely integrated bodies, particularly those employing boundary-layer ingestion, becomes challenging. In this work, a mechanical energy-based approach was taken using the power balance method. This allowed the performance to be analyzed through the mechanical flow power in the fluid domain, disregarding the need for any explicit definition of thrust and drag. Through this, the benefit of boundary-layer ingestion was observed from a wake energy perspective as a decrease in the downstream mechanical energy deposition and associated viscous dissipation. From a propulsion perspective, the reduction in power demand necessary to produce propulsive force indicated the possibility of power savings by utilizing the energy contained within the ingested boundary-layer flow.

Цифровое неравенство как новая форма социального неравенства

The relevance of the article is associated with the active development of digital technologies and the emergence of digital inequality as a new form of social inequality. The article considers the socio-philosophical aspects of digital inequality. The methodological basis of the study is general logical methods of analysis, generalization, comparison, classification, typification. The study used the principles of dialectical and systemic approaches: development, comprehensiveness of study, historicism. Attention is drawn to the fact that there are empirical studies of digital inequality, which consider the levels of digital inequality (global, social, individual), the evolution of forms of digital global inequality. However, a consistent socio-philosophical analysis of digital inequality, offering a theoretical basis and a categorical-conceptual apparatus for understanding this phenomenon, is not presented in scientific knowledge. Currently, there is no unified approach to the concepts of «digital inequality» and «digital capital». There is a need for a general definition of these concepts, which should serve as a starting point for further research of digital inequality and digital capital. Digital inequality exists in various forms related to access to the latest information technologies, the use of information and communication technologies, and social prospects for mastering ICT. The manifestation of digital inequality in the main spheres of society is considered: political, economic, social, and spiritual. Attention is drawn to the connection and interdependence of digital inequality and digital capital. Based on the theory of social capital and the concept of «habitus» by P. Bourdieu, the process of converting digital capital into other forms of capital is studied. The article shows that all types of capital are interconnected and an individual with economic, political, personal, and cultural capital can transform them into digital capital (the ability and skills to use the Internet). Digital capital, in turn, is converted into offline capital. It is concluded that the lack or limitation of access to the digital environment, a low level of digital competencies is one of the main sources of the development of digital inequality as a type of social inequality in a digital society. The article also draws attention to the need to take into account the social and cultural characteristics of individuals when studying the formation of digital capital and digital inequality. A conclusion is made about understanding digital inequality as an integral phenomenon associated with digital capital.

Mapless mobile robot navigation at the edge using self-supervised cognitive map learners.

Navigation of mobile agents in unknown, unmapped environments is a critical task for achieving general autonomy. Recent advancements in combining Reinforcement Learning with Deep Neural Networks have shown promising results in addressing this challenge. However, the inherent complexity of these approaches, characterized by multi-layer networks and intricate reward objectives, limits their autonomy, increases memory footprint, and complicates adaptation to energy-efficient edge hardware. To overcome these challenges, we propose a brain-inspired method that employs a shallow architecture trained by a local learning rule for self-supervised navigation in uncharted environments. Our approach achieves performance comparable to a state-of-the-art Deep Q Network (DQN) method with respect to goal-reaching accuracy and path length, with a similar (slightly lower) number of parameters, operations, and training iterations. Notably, our self-supervised approach combines novelty-based and random walks to alleviate the need for objective reward definition and enhance agent autonomy. At the same time, the shallow architecture and local learning rule do not call for error backpropagation, decreasing the memory overhead and enabling implementation on edge neuromorphic processors. These results contribute to the potential of embodied neuromorphic agents utilizing minimal resources while effectively handling variability.

Relationship between dental caries level and quality of life of communities aged 35-44 years in South Daha District, South Hulu Sungai Regency

Dental caries is the most common dental and oral health problem worldwide, including in Indonesia. Dental caries can be caused by a person’s decreased level of productivity, and severe dental caries can cause pain and difficulty eating and sleeping, thus affecting the quality of life. This study aims to determine the relationship between the level of dental caries and the quality of life of people aged 35-44 years in Daha Selatan District, Hulu Sungai Selatan Regency, South Kalimantan Province. This research used analytic observational method with a cross sectional approach. The population of this research was 106 people of South Daha District aged 35-44 years who were selected using simple random sampling technique. The results of statistical analysis using the Chi-square test obtained a significance value of 0.012 (p < 0.05), indicating a significant correlation between the level of dental caries and the quality of life of 35-44-year-olds. There is a definite need for increasing public awareness of the importance of maintaining oral and dental health to reduce cases of tooth decay caused by dental caries and improve people’squality of life.

The development, psychometric properties and refinement of a food literacy scale for specific and general application

Food literacy continues to be a developing concept, and the need for a universal definition with agreed subconstructs and validated measuring instruments continues to be a priority. The concept describes the knowledge, skills and behaviours needed to meet daily challenges in the face of growing global non-communicable diseases associated with incorrect food behaviour. This research aims to develop, refine and validate a Food Literacy Scale for context-specific and general applications. Food literacy definitions and subconstruct formulations reported elsewhere were used to guide the development of a pool of items (N = 204). This research reports on a process of refinement and validation based on a combination of CTT and Rasch modelling, using results from a middle-income database (population N = 1657, sample n = 862). The application of Rasch analysis provided credible evidence for the quality of the psychometric properties of the instrument. Pragmatic decisions were made about which items to keep or delete, based on qualitative considerations as well as comparison and contrasting of indicators derived from each statistical framework. The final instrument consisted of 95 dichotomous items grouped in six subscales, namely Procurement (11 items), Economics (9 items), Consumption (21 items), Nutrition (24 items), Food safety (17 items), and Socio-cultural aspects (13 items). The large item pool offers scope for further refinement upon implementation in different contexts. The final scale is modular, meaning that one or more subscales can be removed or replaced before implementation. Based on its excellent psychometric properties, the SAFLSTM (South African Food Literacy Scale) is suitable to measure the food literacy of middle-income consumers across many contexts.

Braid stability after flow diverter treatment of intracranial aneurysms: a systematic review and meta-analysis.

The aim of this study was to evaluate the overall rates of braid changes associated with flow diverter (FD) treatment for intracranial aneurysms (IAs). Additionally, we sought to provide an overview of the currently reported definitions related to these complications. A systematic search was conducted from the inception of relevant literature up to April 2023, encompassing six databases. The included studies focused on patients with IAs treated with FDs. We considered four main outcome measures as FD braid changes: (1) fish-mouthing, (2) device braid narrowing, (3) device braid collapsing, and (4) device braid deformation. The data from these studies were pooled using a random-effects model. A total of 48 studies involving 3572 patients were included in the analysis. Among them, 14 studies (39%) provided definitions for fish-mouthing. However, none of the included studies offered specific definitions for device braid narrowing, collapsing, or deformation, despite reporting rates for these complications in six, five, and three studies, respectively. The pooled rates for braid changes were as follows: 3% (95% CI 2% to 4%, I2=27%) for fish-mouthing, 7% (95% CI 2% to 20%, I2=85%) for narrowing, 1% (95% CI 0% to 3%, I2=0%) for collapsing, and 1% (95% CI 1% to 4%, I2=0%) for deformation. The findings of this study suggest that FD treatment for IAs generally exhibits low rates of fish-mouthing, device braid narrowing, collapsing, and deformation. However, the lack of standardized definitions hinders the ability to compare device outcomes objectively, emphasizing the need for uniform definitions for FD braid changes in future prospective studies on FD.

Need for Term Definition in Cardiology-Cardiac Failure and Cardiac Insufficiency: A Short Review

Canadian tertiary care pediatric massive hemorrhage protocols: a survey and comprehensive national review.

Hemorrhage is the leading cause of pediatric death in trauma and cardiac arrest during surgery. Adult studies report improved patient outcomes using massive hemorrhage protocols (MHPs). Little is known about pediatric MHP adoption in Canada. After waived research ethics approval, we conducted a survey of Canadian pediatric tertiary care hospitals to study MHP activations. Transfusion medicine directors provided hospital/patient demographic and MHP activation data. The authors extracted pediatric-specific MHP data from requested policy/procedure documents according to seven predefined MHP domains based on the literature. We also surveyed educational and audit tools. The analysis only included MHPs with pediatric-specific content. The survey included 18 sites (100% response rate). Only 13/18 hospitals had pediatric-specific MHP content: eight were dedicated pediatric hospitals, two were combined pediatric/obstetrical hospitals, and three were combined pediatric/adult hospitals. Trauma was the most common indication for MHP activation (54%), typically based on a specific blood volume anticipated/transfused over time (10/13 sites). Transport container content was variable. Plasma and platelets were usually not in the first container. There was little emphasis on balanced plasma/platelet to red-blood-cell ratios, and most sites (12/13) rapidly incorporated laboratory-guided goal-directed transfusion. Transfusion thresholds were consistent with recent guidelines. All protocols used tranexamic acid and eight sites used an audit tool. Pediatric MHP content was highly variable. Activation demographics suggest underuse in nontrauma settings. Our findings highlight the need for a consensus definition for pediatric massive hemorrhage, a validated pediatric MHP activation tool, and prospective assessment of blood component ratios. A national pediatric MHP activation repository would allow for quality improvement metrics.

Gene amplification in neoplasia: A cytogenetic survey of 80 131 cases.

Gene amplification is a crucial process in cancer development, leading to the overexpression of oncogenes. It manifests cytogenetically as extrachromosomal double minutes (dmin), homogeneously staining regions (hsr), or ring chromosomes (r). This study investigates the prevalence and distribution of these amplification markers in a survey of 80 131 neoplasms spanning hematologic disorders, and benign and malignant solid tumors. The study reveals distinct variations in the frequency of dmin, hsr, and r among different tumor types. Rings were the most common (3.4%) sign of amplification, followed by dmin (1.3%), and hsr (0.8%). Rings were particularly frequent in malignant mesenchymal tumors, especially liposarcomas (47.5%) and osteosarcomas (23.4%), dmin were prevalent in neuroblastoma (30.9%) and pancreatic carcinoma (21.9%), and hsr frequencies were highest in head and neck carcinoma (14.0%) and neuroblastoma (9.0%). Combining all three amplification markers (dmin/hsr/r), malignant solid tumors consistently exhibited higher frequencies than hematologic disorders and benign solid tumors. The structural characteristics of these amplification markers and their potential role in tumorigenesis and tumor progression highlight the complex interplay between cancer-initiating gene-level alterations, for example, fusion genes, and subsequent amplification dynamics. Further research integrating cytogenetic and molecular approaches is warranted to better understand the underlying mechanisms of these amplifications, in particular, the enigmatic question of why certain malignancies display certain types of amplification. Comparing the present results with molecular genetic data proved challenging because of the diversity in definitions of amplification across studies. This study underscores the need for standardized definitions in future work.

Characteristics of Allergic, Eosinophilic, and Overlapping Asthma Phenotypes Among Pediatric Patients with Current Asthma: A Cross-Sectional Study from Saudi Arabia.

Asthma is one of the most common chronic diseases affecting 10%-30% of children in Saudi Arabia. Although data exist on adult asthma phenotyping and endotyping in Saudi Arabia, little is known about asthma phenotypes in Saudi children. This cross-sectional study enrolled pediatric patients diagnosed with bronchial asthma and followed in the pediatric pulmonology clinic of the Abha Maternity and Children Hospital between August 2021 and May 2023. A total of 321 children (aged 5-14 years) were analyzed. The population was classified into allergic [169 (52.6%)], eosinophilic [144 (44.9%)], and overlapping allergic and eosinophilic asthma [97 (30.2%)] phenotypes. Regarding asthma severity, 35.5%, 50.2%, and 14.3% were classified as mild, moderate, and severe, respectively. Of the 321 patients in the study, 124 (38.6%) had at least one asthma exacerbation that required hospitalization. The number of reported missed school days in the previous year was 1571 days [190 (59.2%) patients reported at least one missed school day]. The factors associated with the likelihood of uncontrolled asthma for all study participants included: emergency room (ER) visit last year (OR = 3.7, 95% CI:0.6-15.9]), overlapping eosinophilic and allergic (OR = 3.2, 95% CI = 1.8-5.9), and allergic phenotype (OR = 2.7, 95% CI = 1.3-5.4). The level of asthma control differed significantly among the three asthma phenotypes (p = 0.037). Allergic asthma is the most prevalent asthma phenotype in this study, followed by the eosinophilic phenotype. The research has also shown that several factors predict uncontrolled asthma, including a family history of asthma, previous admission to the PICU, and previous hospitalization ever. There is, therefore, a definite need for multicenter cohort studies to better understand the phenotypes and endotypes of childhood asthma, as it could offer therapeutic and prognostic relevance.

BETWEEN MISSION AND MONEY: A LESSON LEARNED FROM SOCIAL ENTERPRISE IDENTITY

Social Entrepreneurship is a popular business model that proposes entrepreneurship to solve social and environmental problems by selling products or services. In Indonesia, the development of the number and awareness of entrepreneurs supported by the Social Entrepreneurship ecosystem is growing. However, due to the need for a unified definition of 'Social Entrepreneurship' and the slow pace of formal recognition from the government, organizations have developed with mixed practices and results. This study aims to describe the practice of Social Enterprise through the disclosure of corporate identity. Using Identity and Stakeholder Theory, this study explores the five characteristics of identity: mission, activity, governance, performance, and accountability. This multiple case study uses 10 Indonesian Social Enterprises. Data was collected through interviews and speeches in webinars coupled with documentation studies of uploaded narratives, photos, and videos on the company's official website, carried out from March to June 2023. Data analysis uses Nvivo to find themes from various Social Enterprise identity criteria groups. The results show that Social Enterprise has a unique mission and activities that carry a social value where community, empowerment, welfare and sustainability are more emphasized than profit. Institutional commitment as a Social Enterprise is proven by disclosing the impact achieved through impact reports, impact achievement profiles, SDG achievements, or articles in the news column. However, Financial performance is rarely disclosed, even though several companies have disclosed the distribution of their profits. Accountability practice in formal and informal to its stakeholder. This study provides guidelines for how companies disclose and be accountable for their identity as a Social Enterprise.

Reliability of Open Public Electric Vehicle Direct Current Fast Chargers.

The aim was to systematically evaluate the usability of all public electric vehicles (EV) direct current fast chargers (DCFC) in the San Francisco region. To achieve a rapid transition to EVs, a highly reliable and easy to use charging infrastructure is critical to building confidence among consumers. The functionality and usability of all 182 open, public DCFC charging stations with CCS connectors (combined charging system) in the 9 counties of the Bay Area were tested (655 electric vehicle service equipment (EVSE) ports). An EVSE was classified as functional if it charged an EV for 2minutes. Overall, 73.3% of the 655 EVSEs were functional. The causes of the nonfunctioning EVSEs (23.5%) were blank or unresponsive screens or error messages; payment system failures; charge initiation failures; network failures; or broken connectors. In addition, the cable was too short to reach the EV inlet for 3.2% of the EVSEs. A random sampling of 10% of the EVSEs, approximately 8 days after the first evaluation, found no overall change in functionality. The level of functionality found with field testing conflicts with the 95-98% uptime reported by the EV service providers (EVSPs) who operate the EV charging stations. There is a need for precise and verifiable definitions of uptime, downtime, and excluded time, as applied to public EV chargers. The level of failure of the existing public EV DCFC charge infrastructure highlights the importance of improving the system design and maintenance to improve adoption of EVs.

A review of current landscape and definition of septic cardiomyopathy

Abstract Background Septic cardiomyopathy (SCM) is a reversible myocardial dysfunction that is increasingly recognised in critically-ill septic patients. SCM and sepsis cause significant morbidity and mortality. However, the lack of consensus on the diagnostic criteria for SCM makes it difficult to understand how sepsis can impact cardiac function. Purpose To review the current literature regarding SCM and compare the various proposed diagnostic criteria and imaging parameters utilised. Method This literature review comprised of a three-part research method: patient population, imaging modality, and outcomes. Our patient population included critically ill patients diagnosed with sepsis or septic shock. We analysed all cardiac imaging modalities, including TTE, TOE, CT, and CMR. Our outcome was mortality or any related terms. We conducted a comprehensive search of PubMed, EMBASE, and SCOPUS and manually searched for past reviews on the subject. We excluded conference abstracts, review articles, and duplicates using Covidence. Only English-language, adult-audience articles were considered, and the last search update was in November 2022. Result This study analysed 77 papers on SCM, of which 55 were prospective and 18 were retrospective (figure 1). The majority of research was conducted in the ICU, and 61 studies used TTE as the primary imaging modality for assessing SCM. Approximately 44% of the studies evaluated cardiac dysfunction in septic patients using systolic function as the primary metric. About half of the research lacked a clear definition of SCM, and 49% did not provide a definitive LVEF cut-off point (figure 2). 78% of the studies determined the reversibility period to be between 7 and 10 days. The majority of studies required that SCM be diagnosed within 24 hours. However, 66% of the studies did not include any type of imaging follow-up for septic patients with cardiac dysfunction. Conclusion The heterogeneity inherent among these studies points toward the lack of standardisation in measurements and use of various parameters to assesses cardiac dysfunction in septic patients. There is a need for a new definition of SCM that may be better suited to describing the spectrum of cardiac dysfunction in patients with severe sepsis. Further work is required to establish a consensus definition of SCM and a standardised diagnostic approach.Figure 1Figure 2

Citizen participation gaps and challenges in the heating transition: Learning from Dutch community initiatives

The European Union has recognized the significance of community energy initiatives in the energy transition and introduced legislation to promote active consumer participation and renewable energy communities. The Netherlands, with its transition away from natural gas, serves as a valuable case study for understanding the challenges and processes of local ownership and participation in community energy initiatives. The research aims to address the dual challenge of defining local ownership and participation and exploring case-specific applications of these concepts. To achieve this, the study employs the Socio-Ecological Systems Framework and literature on participation, providing a theoretical foundation for analyzing citizen engagement. A mixed-methods approach, including interviews and data collection, is used to examine five Dutch community heating initiatives. The analysis highlights the importance of an enabling participatory environment, inclusive participation, information sharing, and the presence of energy cooperatives for successful citizen engagement. The findings have practical implications for EU energy policy, emphasizing the need for clear definitions, inclusive decision-making processes, and tailored engagement strategies.
