Abstract Offshore wind energy plays a critical role in achieving global decarbonization goals, while the dynamic response mechanisms of megawatt-scale turbines under complex environmental conditions remain insufficiently characterized. Current research often oversimplifies the effects of monopile flexibility and its interaction with soil dynamics, leading to gaps in dynamic predictions. To address this limitation, this study develops a comprehensive 15-degree-of-freedom dynamic model for a 22 MW monopile offshore wind turbine (OWT) that incorporates nonlinear pile flexibility and soil-structure interaction through p-y and Q-z curves. The integrated analytical framework, established using Euler-Lagrange equations, enables coupled analysis of… More > Graphic Abstract

Abstract This paper evaluates the role of aggregated demand-side flexibility from public buildings in supporting renewable energy integration and decarbonization of the Slovenian energy system. Using high-resolution monitoring data from over 100 public buildings and the H2RES energy system optimization model, two long-term scenarios are analyzed for the period 2020–2050: a reference scenario without public building flexibility and a flexibility scenario in which public building heat demand is electrified via heat pumps. The year 2020 is used as an internally consistent optimization reference for demand levels and technology availability, rather than as a statistical reconstruction of… More >

Abstract The global rise in chronic, non-communicable diseases (NCDs) is inextricably linked to metabolic dysfunction, with hyperinsulinaemia acting as a potent upstream driver of ageing and age-related disease. Some of the most burdensome diseases of our time, including type 2 diabetes, cardiovascular disease, cancer, and neurodegenerative conditions, such as Alzheimer’s disease (AD), are largely underpinned by insulin resistance as part of a broader system of metabolic and mitochondrial dysfunction. These pathologies are particularly pronounced in the developed world, where obesity and other lifestyle-related conditions are major contributors to disease burden and premature mortality. As an upstream… More >

Abstract Current energy systems are increasingly complex, considering multi-energy systems, the integration of non-programmable renewable energy sources, and the simultaneous evaluation of multiple evaluation objectives (i.e., costs vs carbon dioxide emissions). This complexity opens the opportunity to explore optimization algorithms as assistance for systematic and automatic management of energy systems. The implementation of a multi-energy system poses multiple challenges, including managing multiple energy vectors with different technologies applied across energy production, energy storage, and renewable energy sources. Also, multi-objective evaluation should be considered to manage reductions in costs and carbon dioxide emissions. Therefore, this paper proposes… More >

Abstract The present study investigated the longitudinal and reciprocal associations between psychological distress and psychological inflexibility among college students. A total of 391 participants (77.2% male; age = 20.31, SD = 0.90) were recruited through cluster sampling, completed the DASS-21 (21-item Depression Anxiety Stress Scale) and AAQ-II (Acceptance and Action Questionnaire–II) at two time points (T1: March 2024; T2: October 2024). After establishing longitudinal measurement invariance, a cross-lagged panel model was estimated while controlling for gender and age. Results from cross-lagged panel modeling (CLPM) revealed significant concurrent correlations between psychological distress and psychological inflexibility at both time… More >

Abstract This study explored how psychology educators in South Africa can be professionally developed to embed Acceptance and Commitment Therapy (ACT) principles into their pedagogy, thereby enhancing psychological flexibility among postgraduate students. Using a Collaborative Action Research approach, seven educators and thirteen students participated in a ten-month intervention comprising four iterative cycles of training, implementation, and reflection. The thematic analysis found that ACT-informed pedagogy not only promoted student resilience, present-moment awareness (mindfulness), and values-based engagement (authenticity) but also catalysed shifts in educator identity toward more reflexive teaching. Students cultivated resilience by learning to tolerate emotional discomfort More >

Abstract The integration of renewable energy introduces significant uncertainty into daily power system operation scenarios. Traditional deterministic unit commitment methods struggle to adapt to these conditions, often resulting in poor economic performance and high curtailment rates in planning outcomes. To address these challenges, this paper proposes a coordinated thermal power-energy storage planning methodology for managing renewable energy uncertainty. First, the operational effectiveness of daily unit commitment under uncertain renewable energy scenarios is analyzed, with quantitative assessment of how different commitment strategies impact supply-demand balance and economic performance. Subsequently, by conducting flexibility evaluation under multiple renewable energy… More >

Abstract This paper develops an innovative computational model for assessing the Carbon Emission Factor (CEF) of provincial power systems that incorporates inter-provincial electricity transfers and hybrid generation portfolios combining conventional and renewable sources. A key contribution lies in evaluating how deep regulation of thermal power plants influence the carbon intensity of coal-fired generation and coal-fired generation together with high penetration renewables. Furthermore, the study quantitatively analyzes the role of renewable energy consumption and the prospective application of Carbon Capture and Storage (CCS) in reducing system-wide CEF. Based on this framework, the paper proposes phased carbon emission… More > Graphic Abstract

Abstract The increasing use of renewable energy sources, combined with the increase in electricity demand, has highlighted the importance of energy flexibility management in electrical grids. Energy flexibility is the capacity that generators and consumers have to change production and/or consumption to support grid operation, ensuring the stability and efficiency of the grid. Thus, Local Flexibility Markets (LFMs) are market-oriented mechanisms operated at different time horizons that support flexibility provision and trading at the distribution level, where the Distribution System Operators (DSOs) are the flexibility-demanding actors, and prosumers are the flexibility providers. This paper investigates the… More >

Abstract Background: With the proliferation of smartphones, adolescent mobile phone dependency has intensified, potentially precipitating academic burnout and other adverse outcomes among students. Contemporary study mostly examines college populations, resulting in a lack of exploration on the internal mechanisms connecting mobile phone dependency to academic burnout. In addition to analysing the chain-mediated effects of sleep quality and cognitive flexibility, this study sought to provide theoretical insights for prevention by applying the Conservation of Resources theory to examine the relationship between academic burnout and mobile phone dependency among middle and high school students. Methods: A cluster convenience… More >
