description: In the face of mounting global interest in reducing greenhouse gas emissions and achieving carbon neutrality, there is an urgent need to develop and implement diverse measures. In particular, it is imperative to explore the potential of utilising waste heat from industrial processes and power generation, as this has the potential to significantly enhance energy efficiency and reduce greenhouse gas emissions while also capturing otherwise wasted energy. Concurrently, supercritical CO2 power generation is regarded as a prospective technology for fossil, nuclear, solar, thermal energy storage and waste heat recovery applications, attributable to its elevated thermodynamic efficiency, miniaturised plant configuration, and environmental stability. sCO2 power cycles function above the critical point of CO2 (31.1°C, 7.38 MPa) and deliver higher energy density and heat transfer performance in comparison to conventional power cycles. It is particularly effective for power generation systems using medium-temperature waste heat and has the advantage of being applicable to various industrial environments. KEPCO (Korea Electric Power Corporation) has been promoting research and development of sCO2 power cycles as a promising future technology since 2014. Following a series of feasibility studies, KEPCO aimed to construct an MW-scale sCO2 power generation system that recovers waste heat at low temperatures and has the capacity to reduce risks in the early stages of development. Additionally, the system was designed to achieve a high probability of demonstration success and initial marketability. In 2016, with the support of KEPCO, we initiated a strategic project to achieve a net output of 2MWe by recovering waste heat from engines. A suitable onshore power generation engine to output MW-scale sCO2 power output was selected as well as a partial heating sCO2 cycle to recover waste heat from the engine exhaust. A design feasibility study was also conducted. This paper provides an overview of the development of 2MW KEPCO sCO2 power system designed to recover waste heat. This paper also describes the cycle analysis results and the specifications and fabrication of major equipment (turbine, compressor, heat exchanger, etc.).

description: The goal of this article is to analyze from a narrative point of view British television drama Downton Abbey (six seasons from 2010 to 2015), to show how a coherent ideological system is expressed by a television series. Previous literature has identified a “conservative” ideology in Downton Abbey and this article aims to describe the main features of this ideology and the narrative elements that propose them. A structural semiotic approach (mainly based on the theory and models of Algirdas Julien Greimas) has been used to analyze “deep” and abstract levels of narration, such as narrative functions and subjects’ programs. Textual analysis shows how a highly stratified society, led by aristocracy, is described and proposed as a good model. Moreover, aristocracy is proposed as a sacred space that assures this order and that cannot be altered. In fact, the final part of the article analyzes a recurring narrative schema in Downton Abbey: when social change (otherwise tolerated) violates the sacred border of aristocracy, the sacrifice of a character is requested.

description: The word minority, when used incorrectly, is a condescending term that segregates, inaccurately represents groups as being smaller or less important, and fuels microaggressions. Scientific societies and other institutions have normalized using the word minority, or the “M word,” to refer to members of underrepresented groups in Science, Technology, Engineering, and Mathematics (STEM). The message put forth using the term minority often directly conflicts with the inclusive agenda these societies seek to enact. More inclusive acronyms such as PEER (Persons Excluded because of their Ethnicity or Race) have been created to more accurately reflect the active process of exclusion by institutions. Here, we detail the rationale behind the decision to eradicate the word minority from the name of a prominent committee within the American Society for Cell Biology (ASCB). The ASCB Minority Affairs Committee changed its name to the Maximizing Access to Cell Biology for PEERS Committee. Herein, we emphasize the basis for the name change and highlight the contradictions intrinsic to the word minority in this context. We highlight why swift action is required for this rewording within the context of a committee dedicated to supporting the inclusion of PEERs in the scientific community.

description: sCO2 energy conversion cycles technology development is reaching the MW-scale cycle demonstration phase. At the moment of this abstract writing, the STEP plant is going through the different phases of commissioning and has already produced electrical power. Other demonstration projects are reaching the end of the design phase and forecast a commissioning start in 2026. Nuovo Pignone Baker Hughes is part of the Desolination project consortium. Desolination project aims to decarbonize the desalination process in arid regions by demonstrating in a real environment the efficient coupling of a concentrating solar power plant to a direct osmosis desalination system. The sCO2 cycle involved in this process is a Transcritical evolving a blended CO2 mixture optimized to enable condensation in hot ambient temperature areas. Nuovo Pignone contributes to the Desolination project developing the pump and the expander of the sCO2 cycle. Expander development has reached the completion of the detailed design phase and the procurement of long lead material has started. This paper will provide a comprehensive overview of the expander development process, from conceptual design through to detailed design, displaying the key technology challenges peculiar of sCO2 expanders and illustrating the engineering methodologies applied to optimize the expander design.

description: This paper presents the design and optimization of a cable-driven parallel polishing robot (CDPPR) with kinematic error modeling and introduces an improved non-dominated sorting genetic algorithm II (NSGA-II) for multi-objective optimization. First, the mechanical design and kinematic and static modeling of the CDPPR are conducted. Subsequently, a kinematic error transfer model is established based on the evidence theory by considering the change of exit points of cables, and an error index is derived to measure the accuracy of the robot. Besides, another two performance indices including the workspace and static stiffness are also proposed. Thus, a multi-objective optimization model is established to optimize the workspace, static stiffness, and error index, and an improved NSGA-II is developed. Finally, an experimental scaled prototype of the CDPPR is constructed, and numerical examples and experimental results demonstrate the effectiveness of the improved NSGA-II and the stability of the optimal configuration.

description: The Brayton Loop facility at Sandia National Laboratories (SNL) has been instrumental in identifying technology gaps and developing solutions critical for the commercialization of supercritical carbon dioxide (sCO2) power cycles. The benefits afforded by these new conversion technologies are required to fully leverage the potential from the next generation of nuclear reactors: increased efficiency, smaller footprint, and the ability to use dry cooling. While the recompression closed-loop Brayton Cycle (RCBC) test loop test program has been successful, its full potential has been stymied by the poor reliability of the turbine-alternator-compressor (TAC) bearings. While many of the early events were due to poor controllability issues, resulting from the first-generation power electronics, it demonstrated their lack of robustness necessary for these high-power density machines. Despite contactless operation at speed, foil air bearings are in contact with the shaft at all speeds that are below that required for lift-off; for the foil bearings in the TAC it's around 8,000 RPM. Therefore, surface to surface contact occurs during start and shutdown, leading to wear. These unpreventable events contribute to loss of low friction surface treatment and are life limiting. While fully developed foil bearings are commercially applied to air cycle machines and small gas turbines (microturbines), rotors of low mass, this failure mechanism is amplified for large commercial sCO2 systems with heavy rotors and larger loads, rendering them unsuitable for future commercial small modular reactors (SMRs). It was therefore decided to identify and test more robust bearing solutions that would not only improve run time accumulation and facilitate performance and cycle configuration testing, but also demonstrate solutions which are scalable and better suited for large commercial systems. As part of the TAC improvement program, and after the control system upgrade, the bearings were identified as the main technology to increase TAC reliability and efficiency. TACs currently employ aerodynamic foil type bearings. This report considers the retrofit design, acceptance testing, and the initial testing of a TAC retrofitted with externally pressurized porous (EPP) gas bearings. Both radial and axial constraint are required to support the rotor and react the axial thrust load. This was accomplished by replacing the compressor journal and thrust bearings with a single EPP bearing assembly, and a simple replacement of the journal on the turbine side.

description: The management of electrical energy represents a significant challenge that must be overcome, given that electricity must be consumed immediately upon production. In this regard, an innovative energy storage solution is proposed, employing a heat pump with a supercritical Recompression Brayton cycle (RBC) utilizing pure s-CO2 and CO2–based mixtures to enhance the system's performance. This analysis encompasses a techno-economic, energetic, entropic and exergetic study, with consideration given to the levelized cost of storage (LCOS). This study is concerned with the effect of binary mixtures based on pure s-CO2 on the round-trip efficiency and LCOS, considering the irreversibilities associated with each component of the cycle. The methodology employed in the calculation of the plant performance entails the optimization of the parameters of work of the components within the cycle under study. The present study has utilised simulations which have been based on code developed in the programming languages MatLab and Python. The findings of the present study demonstrate that the mixture gives rise to a lower LCOS in comparison to pure s-CO2 (151.11 $/MWh). The lowest LCOS is observed in CO2/Xe, with a value of 138.26 $/MWh. Furthermore, mixtures such as CO2/Kr and CO2/H2S have been observed to exhibit LCOS values of 142.13 $/MWh and 146.64 $/MWh, respectively. In addition, the round-trip efficiency of pure s-CO2 is estimated to be approximately 57.4%, which is outperformed by CO2/Kr and CO2/H2S mixtures, which achieve round-trip efficiencies of 59.7% and 58.3%, respectively. However, when employing a CO2/Xe mixture within the cycle, a round-trip efficiency analogous to that of pure s-CO2 is realised.

description: The inclusion of culture in the design of information and communication technologies is a hollow cry for change and the inclusion of others. This paper explores interdisciplinary research across the fields of library and information sciences, open education, and instructional design and technology to examine representations of culture in social justice contexts. A literature review from 2015-2020 begins to situate this study. The findings reveal that to move towards an education in social justice requires both vicarious experiences and live interactions. Further, the article ends with a critique of social justice as a concept that challenges the non-oppressed to give up an unmeasured amount of power and privilege.

description: Surface acoustic waves have emerged as one of the potential candidates for the development of next-generation wave-based information and computing technologies. For practical devices, it is essential to develop the excitation techniques for different types of surface acoustic waves, especially at higher microwave frequencies, and to tailor their frequency versus wave vector characteristics. We show that this can be done by using ultrashort laser pulses incident on the surface of a multilayer decorated with a periodic array of metallic nanodots. Specifically, we study surface acoustic waves in the dielectric substrate Si/SiO2 decorated with a square lattice of thin Ni80Fe20 (Py) dots. Using a femtosecond laser-based optical pump-probe measurement, we detect a number of high-frequency phononic modes. By performing finite element simulations, we identify them as Sezawa modes from the second and third Brillouin zone in addition to the modes confined within the Py dots. The frequency of the Sezawa modes strongly depends on the period of the Py dots and varies in the range between 5 to 15 GHz. Both types of waves cover the same frequency range for Py dots with period less than 400 nm, providing a promising system for magnetoelastic studies.

description: This paper describes the development of a supercritical carbon dioxide test facility to mimic the primary heat exchanger inlet operation conditions of a recompression sCO2 Brayton cycle. The experimental facility is used to test and evaluate the heat transfer performance of a particle-to-sCO2 heat exchanger for concentrated solar power applications. The sCO2 flow loop is comprised of five main components: a positive displacement gear pump, piston accumulator, sCO2 preheater, experimental test section, and sCO2 post cooler. The test facility is instrumented with measurement devices to quantify the heat and mass flows within the system. The loop operates at isobaric conditions up to 20 MPa and is split into a hot and cold side. On the cold side, the sCO2 is cooled below room temperature by the post cooler, increasing the density of the sCO2 high enough such that it can be circulated using the gear pump. The 10.8 kW preheater delivers sCO2 to the test section at temperatures up to 600°C at flow rates up to 0.013 kg s-1. Within the test section the sCO2 is further heated by inert CARBO HSP 40/70 particles. The development of the novel particle-to-sCO2 heat exchanger is also reported in this work. The heat exchanger was tested at dilute and dense flow conditions in the particle domain. The heat transfer performance and particle-to-sCO2 recovery effectiveness are characterized and compared to model predictions. By validating the model with the collected experimental data, it can be used to guide the design of future larger scale particle-to-sCO2 heat exchangers.

description: Background: Multimorbidity is associated with greater likelihood of disability, health-related quality of life, and mortality, greater than the risk attributable to individual diseases. The objective of this study is to examine the association between unique multimorbidity combinations and prospective disability and poor self-rated health (SRH) in older adults in Europe. Methods: We conducted a prospective analysis using data from the Survey of Health, Ageing and Retirement in Europe in 2013 and 2015. We used hierarchical models to compare respondents with multiple chronic conditions to healthy respondents and respondents reporting only one chronic condition and made within-group comparisons to examine the marginal contribution of specific chronic condition combinations. Results: Less than 20% of the study population reported having zero chronic conditions, while 50% reported having at least two chronic conditions. We identified 380 unique disease combinations among people who reported having at least two chronic conditions. Over 35% of multimorbidity could be attributed to five specific multimorbidity combinations, and over 50% to ten specific combinations. Overall, multimorbidity combinations that included high depressive symptoms were associated with increased odds of reporting poor SRH, and increased rates of ADL-IADL disability. Conclusions: Multimorbidity groups that include high depressive symptoms may be more disabling than combinations that include only somatic conditions. These findings argue for a continued integration of both mental and somatic chronic conditions in the conceptualization of multimorbidity, with important implications for clinical practice and healthcare delivery.

description: Introduction Psychotic-like experiences (PLEs) may occur due to changes in weighting prior beliefs and new evidence in the belief updating process. It is still unclear whether the acquisition or integration of stable beliefs is altered, and whether such alteration depends on the level of environmental and belief precision, which reflects the associated uncertainty. This motivated us to investigate uncertainty-related dynamics of belief updating in relation to PLEs using an online study design. Methods We selected a sample (n = 300) of participants who performed a belief updating task with sudden change points and provided self-report questionnaires for PLEs. The task required participants to observe bags dropping from a hidden helicopter, infer its position, and dynamically update their belief about the helicopter's position. Participants could optimize performance by adjusting learning rates according to inferred belief uncertainty (inverse prior precision) and the probability of environmental change points. We used a normative learning model to examine the relationship between adherence to specific model parameters and PLEs. Results PLEs were linked to lower accuracy in tracking the outcome (helicopter location) (β = 0.26 ± 0.11, p = 0.018) and to a smaller increase of belief precision across observations after a change point (β = −0.003 ± 0.0007, p < 0.001). PLEs were related to slower belief updating when participants encountered large prediction errors (β = −0.03 ± 0.009, p = 0.001). Computational modeling suggested that PLEs were associated with reduced overall belief updating in response to prediction errors (βPE = −1.00 ± 0.45, p = 0.028) and reduced modulation of updating at inferred environmental change points (βCPP = −0.84 ± 0.38, p = 0.023). Discussion We conclude that PLEs are associated with altered dynamics of belief updating. These findings support the idea that the process of balancing prior belief and new evidence, as a function of environmental uncertainty, is altered in PLEs, which may contribute to the development of delusions. Specifically, slower learning after large prediction errors in people with high PLEs may result in rigid beliefs. Disregarding environmental change points may limit the flexibility to establish new beliefs in the face of contradictory evidence. The present study fosters a deeper understanding of inferential belief updating mechanisms underlying PLEs.

Abstract

This paper redefines ego not as a fixed psychological entity or symbolic abstraction rooted in self-image, but as the emergent artifact of unresolved coherence gaps within a dynamic resonance field. In conventional psychology and philosophy, ego is often treated as a stable structure—something to be built, transcended, or dissolved. However, within the CODES Intelligence framework, we show that ego is neither essential nor illusory. It is instead the local signature of phase misalignment between internal signal structures (thoughts, emotions, memory loops) and external resonance fields (social, relational, environmental systems).

Rather than being a “thing,” ego is modeled here as a false attractor—a locally stable but globally incoherent structure that self-perpetuates under feedback from uncertainty. This misalignment generates recursive identity reinforcement through contradiction buffering, projection, and semantic loop closure. In this sense, ego is not a cause but a symptom—a surface distortion indicating deeper systemic incoherence.

We formalize ego collapse as a phase realignment event in high-entropy identity systems and outline mechanisms through which ego disintegrates when coherence increases across nested fields (e.g., body, relationship, environment, computation). Drawing on resonance-based metrics such as Phase Alignment Score (PAS) and coherence field topologies, we propose both empirical and computational methodologies to observe, model, and reduce ego as a function of alignment—not belief or narrative control.

This new model integrates psychoemotional experience with mathematical resonance theory and provides a unifying scaffold across mental health, artificial intelligence, somatic therapy, and spiritual practice. By treating ego as a coherent-field failure mode, we shift from managing identity to phase-locking emergence—allowing the self to act as a node in a living field rather than a container of uncertainty.

This study examines the influence of childcare provision on older adults’ health trajectories in the United States with a particular focus on racial/ethnic differentials.Analyzing nationally representative, longitudinal data on grandparents over the age of 50 from the Health and Retirement Study (1998–2010), we conduct growth curve analysis to examine the effect of living arrangements and caregiving intensity on older adults’ health trajectories, measured by changing Frailty Index (FI) in race/ethnic subsamples. We use propensity score weighting to address the issue of potential nonrandom selection of grandparents into grandchild care.We find that some amount of caring for grandchildren is associated with a reduction of frailty for older adults, whereas coresidence with grandchildren results in health deterioration. For non-Hispanic black grandparents, living in a skipped generation household appears to be particularly detrimental to health. We also find that Hispanic grandparents fare better than non-Hispanic black grandparents despite a similar level of caregiving and rate of coresidence. Finally, financial and social resources assist in buffering some of the negative effects of coresidence on health (though this effect also differs by race/ethnicity).Our findings suggest that the health consequences of grandchild care are mixed across different racial/ethnic groups and are further shaped by individual characteristics as well as perhaps cultural context.

description: Carbon dioxide (CO₂) is a commercially viable working fluid for transcritical high-temperature heat pumps (HTHPs), but its low critical temperature (31°C) limits efficiency with cold sources above 40°C. Using a CO₂-based mixture with a higher critical temperature dopant can mitigate this issue by reducing temperature differences at the evaporator and enhancing heat transfer. This study focuses on fluorobenzene (C6H5F) as a dopant due to its high critical temperature, low cost, negligible global warming potential, and regulatory compliance in Europe. To address the lack of vapor-liquid equilibrium (VLE) data for CO₂-fluorobenzene mixtures, an experimental campaign is conducted at the University of Brescia to measure bubble points using an isochoric apparatus. The data are used to select the most suitable equation of state for cycle calculations. The heat pump’s analysis – both at design and off-design- is evaluated in a case study of integration with an Air Separation Unit (ASU). The authors selected this specific case study because it represents one of the most continuous processes in the industry, whereas the integration of heat pumps is often challenged by the intermittency of heat sources in industrial applications. Waste heat from the ASU’s main air compressor is exploited through an intermediate closed-loop water cooling circuit operating at around 90°C. The heat pump upgrades this thermal energy to supply a local district heating network with a design supply temperature of 110°C. At this design point, the system achieves a coefficient of performance (COP) of 7.7, decreasing to 6.2 for higher off-design supply temperatures (e.g., 127°C).

description: Abstract:Background: While effective interventions have been developed to support families where a parent has a mental illness in Adult Mental Health Services, embedding and sustaining them is challenging resulting in families not having access to support. This study developed an explanatory model of influencers that had enabled sustainability of the Let's Talk intervention in one service. Methods: A participatory case study was used to build an explanatory model of sustainability at the service using theoretical frameworks. Qualitative and quantitative data was collected about practitioner's practice and the organisation's implementation process and capacity to support practice. A local research group worked with the researcher using a transforming data approach through description, analysis and interpretation. Results: Influencers were grouped into four major categories: (1) External social, political and financial context, (2) Resources, (3) Prior organisational capacity and (4) Sustainability Factors. The last category, Sustainability factors, was divided into three subcategories: (4.1) Practitioner (4.2) Organisation and (4.3) Parent-Client. These categories form part of an explanatory model for the key influencers of continued practitioner practice and organisational capacity to support practice. Conclusions and implications for practice: In this case study, the pre-existing organisational context along with practitioner, organisation and parent-client factors operated together to influence sustainability. The results suggest that sustainability is more likely to be supported by both linking Let's Talk to existing organisational identity, capacity, structures and relationships and by supporting mutual adaptations to improve the fit. Additionally, by understanding that setbacks are common and ongoing adjustments are needed, implementers are able to have realistic expectations of sustainability.

Individual Troubles, Shared Troubles: The Multiplicative Effect of Individual and Country-Level Unemployment on Life Satisfaction in 95 Nations (1981–2009)

description: Although the negative association between unemployment and life satisfaction is well documented, much theoretical and empirical controversy surrounds the question of how unemployment actually shapes life satisfaction. Previous studies suggest that unemployment may endanger subjective well-being through individual experiences, contextual influences, or a combination of both. Drawing on data from the World and European Values Surveys, National Accounts Official Country Data, Social Security Programs Throughout the World Reports, World Development Indicators, and World Income Inequality databases for 398,533 individuals in 95 nations (1981–2009), we use three-level hierarchical linear models to test four competing theory-based hypotheses—that unemployment shapes life satisfaction through individual, contextual, additive, or multiplicative effects. Our results support a multiplicative interaction between individual- and country-level unemployment. Unemployed individuals are less satisfied than other individuals, and when unemployment rates rise, their satisfaction drops even further below students, homemakers, and employed individuals; retirees, however, become more similar to the unemployed. We discuss these findings in light of previous theoretical models to argue for a model where individual unemployment is understood in the context of diverse labor force statuses and national unemployment rates. We conclude with policy suggestions aiming to address the negative consequences of unemployment through individualized and contextualized plans.
The role of self-assessment in the facilitation of entrepreneurial competencies in learners who are studying on entrepreneurial learning courses in England

description: This study explored whether self-assessment facilitates the process of generating entrepreneurial competencies in learners who were studying on entrepreneurial learning courses in England. The focus was on how learners experience personal growth and transformation through the learning process and how this could be demonstrated through self-assessment practices. This was achieved by looking at the cognitive processes that a learner needs to engage with in order to conduct selfassessments and the relationship between these and self-regulation. The research was positioned within a holistic philosophy of education, where the learners’ physical, personal, social, emotional, and spiritual well-being, as well as cognitive aspects of learning, are equally important. This was a qualitative study framed by an interpretivist philosophical position. The chosen methods were semi-structured interviews of eight educators and seven learners and document analysis, which provide an understanding of the phenomenon by looking at how the participants interpret the events based on their individual thought processes. This research contributes to our understanding of self-assessment practices on entrepreneurial learning courses and the impact that this could have on higher education more broadly. This study made an original contribution to the knowledge by increasing our understanding of selfassessment through the production of new information by identifying a typology of the forms of self-assessment that learners participate in on entrepreneurial learning courses. The typology identifies the skills that the learner requires in order to complete the self-assessments, outlining the benefits for learners who participate in self-assessments, discussing the factors that contribute to a successful selfassessment, and describing the role of the educator as a facilitator in the process of self-assessment.

description: BACKGROUND: Factors contributing to the lower likelihood of urologist follow-up among African American (AA) men diagnosed with prostate cancer may not be strictly related to patient factors. The authors investigated the relationship between crime, poverty, and poor housing, among others, and postdiagnosis urologist visits among AA and white men. METHODS: The authors used linked cancer registry and Medicare claims data from 1999 through 2007 for men diagnosed with American Joint Committee on Cancer stage I to III prostate cancer. The USA Counties and County Business Patterns data sets provided county-level data. Variance components models reported the percentage of variation attributed to county of residence. Postdiagnosis urologist visits for AA and white men were investigated using logistic and modified Poisson regression models. RESULTS: A total of 65,635 patients were identified; 87% of whom were non-Hispanic white and 9.3% of whom were non-Hispanic AA. Approximately 16% of men diagnosed with stage I to III prostate cancer did not visit a urologist within 1 year after diagnosis (22% of AA men and 15% of white men). County of residence accounted for 10% of the variation in the visit outcome (13% for AA men and 10% for white men). AA men were more likely to live in counties ranked highest in terms of poverty, occupied housing units with no telephone, and crime. AA men were less likely to see a urologist (odds ratio, 0.65 [95% confidence interval, 0.6-0.71]; rate ratio, 0.94 [95% confidence interval, 0.92-0.95]). The sign and magnitude of the coefficients for the county-level measures differed across race-specific regression models of urologist visits. CONCLUSIONS: Among older men diagnosed with stage I to III prostate cancer, the social environment appears to contribute to some of the disparities in postdiagnosis urologist visits between AA and white men.
