Predictors and correlates of loneliness and social isolation in people with dementia: longitudinal findings from the IDEAL programme
Data availability: IDEAL data were deposited with the UK data archive in April 2020. Details of how to access the data can be found here: http://reshare.ukdataservice.ac.uk/854293Objective: To identify predictors of loneliness and social isolation experienced by people with dementia at baseline and over time.
Methods: Using data from the Improving the Experience of Dementia and Enhancing Active Life (IDEAL) cohort study (2014-2018), we examined the prevalence and predictors of loneliness and social isolation in 1,547 people with mild-to-moderate dementia over 24 months. Loneliness was measured using the six-item De Jong Gierveld Scale at baseline and 24 months and social isolation by the six-item Lubben Social Network Scale at baseline, 12 and 24 months. Generalised linear mixed effects models examined possible predictors of loneliness and social isolation including individual characteristics, depression, cognition, cultural participation, and neighbourhood characteristics.
Results: At baseline 35.4% of people with dementia were categorised as being lonely and 28.8% as socially isolated, increasing to 39.3% and 32.0% two years later. Over the 24-month follow-up none of these predictors were associated with changes in social isolation scores. Only perceived neighbourhood trust was associated with change in loneliness longitudinally. At baseline, depressive symptoms, living alone, smaller social networks and lower neighbourhood trust were associated with greater loneliness. Cross-sectionally, loneliness and lower cognitive ability were associated with greater social isolation, and greater cultural participation, more green and blue spaces nearby and higher neighbourhood trust were associated with lower social isolation scores.
Conclusions: The findings highlight the importance of the local environment and cultural participation for people with dementia. Enhancing interactions with the local neighbourhood through initiatives such as dementia friendly communities may help to reduce loneliness and social isolation.‘Improving the experience of Dementia and Enhancing Active Life: living well with dementia.

Nucleation control strategy for sustainable aluminium: Improving Fe removal efficiency or increasing Fe-tolerance
Achieving ultra-low Fe level or refining Fe-containing intermetallic compounds (Fe-IMCs), both governed by heterogeneous nucleation, remains a major challenge for development of high-performance recycled Al alloys. This study demonstrates that the sensitivity of Fe-IMC formation to casting conditions is dictated by nucleation difficulty, which is controlled by both kinetic factors (diffusion time) and thermodynamic driving forces (nucleation and continuous undercooling). We provide the first direct evidence for dual-size primary Fe-IMCs and their distinct nucleation pathways: large P1-α-Al₁₅(Fe,Mn)₃Si₂ particles originating from non-equilibrium θ-Al₁₃Fe₄ nucleated at higher temperatures, and nanoscale P2-α-Fe particles nucleating heterogeneously on MgAl₂O₄ oxides at lower temperatures with larger nucleation undercooling. Building on this new mechanistic understanding, two casting strategies were developed: (1) promoting Fe-IMC nucleation to enhance Fe removal down to 0.3 wt%, and (2) suppressing Fe-IMC formation to increase Fe tolerance and refine second-phase particles, enabled by tuning pouring temperature, cooling rate, and casting routes. A comprehensive process map linking Fe-IMC formation to cooling rate and pouring temperature is established, providing a predictive framework for process optimization. These insights position nucleation-control-based design as a powerful approach for sustainable aluminium production.This work was financial supported by the EPSRC (UK) for under grant number EP/N007638/1 (Future Liquid Metal Engineering Hub) and Brunel University of London BRIEF award (11937131)

<i>H</i><sub>∞</sub> Fuzzy Control for A Class of Cyber-Physical Systems Under Frequency-Duration-Constrained Replay Attacks
In this article, the H∞ fuzzy control problem is investigated for a class of nonlinear systems subject to replay attacks with frequency-duration constraints. Owing to the vulnerability of the open shared communication network, the information transmitted from the sensor to the controller may be exposed to replay attackers. A novel yet comprehensive replay attack model is constructed to characterize the repeated replay behavior of the adversary. On the basis of the constructed model, a fuzzy controller is designed to guarantee asymptotic stability and the desired H∞ performance. By employing Lyapunov stability theory and the orthogonal decomposition technique, sufficient conditions are derived to ensure the existence of the desired controller parameter. Finally, simulation results are presented to verify the effectiveness and correctness of the proposed fuzzy controller for T-S fuzzy systems under replay attacks.This work was supported in part by the National Natural Science Foundation of China under Grants
