Incentivizing flexible consumption of end-users is key to maximizing the value of local exchanges within Renewable Energy Communities. If centralized coordination for flexible resources planning raises concerns regarding data privacy and fair benefits distribution, state-of-the-art approaches (e.g., bi-level, ADMM) often face computational complexity and convexity challenges, limiting the precision of embedded flexible models. This work proposes an iterative resolution procedure to solve the decentralized flexibility planning with a central operator as a coordinator within a community. The community operator asks for upward or downward flexibility depending on the global needs, while members can individually react with an offer for flexible capacity. This approach ensures individual optimality while converging towards a global optimum, as validated on a 20-member domestic case study for which the gap in terms of collective bill is not more than 3.5% between the decentralized and centralized coordination schemes.
Postoperative cognitive dysfunction (PCD), now a part of the perioperative neurocognitive troubles spectrum, is a cognitive decline that lingers between 30 days and 12 months after surgery. It preferentially affects aged and frail patients, and is associated with a loss of autonomy, the degradation of the quality of life, more institutionalisation, a higher mortality, and, overall, carries a subtantial economical burden. Despite a growing interest, its management remains limited by underdiagnosis, the heterogeneity of its definitions, the heterogeneity of the tests and of the windows for evaluation, as well as by the lack of a consensus on a unique and routinely performable protocol. Screening tools facilitate the detection of a pre-existing neurocognitive trouble, of major risk factors, while neuropsychological test batteries for each domain and statistical approaches remain central for research. The present understanding of the underlying mechanisms points toward a key role for post-surgical neuroinflammation, favored by age-linked cerebral vulnerability, and sustained by postoperative complications. Prevention is based on preoperative stratification, optimization of modifiable factors, and targeted intraoperative strategies. Non-pharmacological interventions seem particularly promising. Dexmetomidine is the most studied pharmacological agent, while other solutions are yet to be confirmed. Future development should prioritise the harmonisation of the criteria of diagnosis, the description of predictive biomarkers, and the implementation of personalised approaches, potentially with the help of artificial intelligence. This narrative review of recent literature focuses on detection and diagnosis, prevention, and therapeutic options for PCD.
The point-dipole approximation is commonly applied to simplify light-matter interactions. As previously reported, it is inaccurate near nanoplasmonic structures as those may strongly enhance higher-order multipoles. However, the enhancement of higher-order effects in the far-field, especially for dipole-forbidden molecular emitters, remains largely underexplored. In this study, we examine the breakdown of the point-dipole approximation for light emitted by four molecular systems, with dipole-allowed and dipole-forbidden transitions, all near an scanning tunneling microscopy tip-like plasmonic structure. Importantly, we demonstrate that effects beyond dipolar and quadrupolar orders are observable in both total decay and radiative rates, rendering typically dark molecular systems efficiently fluorescent in the far field. Radiative rates from the nanoplasmonic cavity exceed those of typical dipole-allowed molecular emitters and are thus predicted as observable in practical experiments.
ABSTRACT This work aims to investigate the impact of the substrate temperature on the growth mechanism of allylamine‐based plasma polymer films (PPF). A comprehensive study of the PPF physicochemical properties, including the mechanical properties, the glass transition temperature, the chemical composition, the cross‐linking degree and the deposition kinetics, is performed and correlated to plasma chemistry. As the substrate temperature evolves from ‐10°C to 45°C, the glass transition temperature is observed to increase from 75°C to 230°C. This evolution is correlated to an increase in cross‐linking degree, modulated by the energy density brought by ion bombardment during film growth. The energy density is, in turn, significantly influenced by the deposition kinetics which strongly depend on the thermal conditions of the substrate, as evidenced by the growth rate decrease from 5.4 to 1.6 nm/min with the substrate temperature. Similarities are observed with another allyl‐based PPF family, suggesting a comparable growth mechanism but distinct film properties attributed to differences in growth rate. Overall, this study highlights the combined role of precursor chemistry and substrate temperature as key parameters for fine tuning of plasma polymer film properties.
PurposeAlthough the literature highlights the critical role of family firms in ensuring the sustainability of our economies, few studies examine how these firms differ from nonfamily firms in integrating environmental considerations into their innovation strategies. To address this gap, this research draws on stakeholder theory and the socioemotional wealth perspective to examine the relationship between the family status of the firm and green innovation intensity, while also investigating the moderating role of environmental awareness longevity.Design/methodology/approachThis research relies on a quantitative analysis of a sample of 231 private firms located in Wallonia (Belgium). Regression analyses are conducted to test the direct effect of family status of the firm on green innovation intensity and the moderating effect of the duration of environmental awareness.FindingsThe results reveal a positive relationship between the family status of the firm and green innovation intensity. However, this positive effect weakens as the duration of environmental awareness increases. This suggests that family firms are particularly supportive of green innovations in the early stages of their environmental awareness.Originality/valueThis study contributes to the literature at the intersection of green innovation and family business by showing that family firms are more inclined than nonfamily firms to pursue green innovations. By introducing environmental awareness longevity as a moderating factor, the research advances existing knowledge by revealing the temporal conditions under which family firms display greater proactivity in the adoption of green innovations.
