    The whole-life-cycle state of charge (SOC) prediction plays a significant role in various applications of lithium-ion batteries, but with great difficulties due to their internal capacity, working temperature, and current-rate variations. In this paper, an improved feedforward-long short-term memory (FF-LSTM) modeling method is proposed to realize an accurate whole-life-cycle SOC prediction by effectively considering the current, voltage, and temperature variations. An optimized sliding balance window is constructed for the measured current filtering to establish a new three-dimensional vector as the input matrix for the filtered current and voltage. Then, an improved steady-state screening model is constructed for the predicted SOC redundancy reduction that is obtained by the Ampere-hour integral method and taken as a one-dimensional output vector. The long-term charging capacity decay tests are conducted on two batteries, C7 and C8. The results show that the battery charging capacity reduces significantly with increasing time, and the capacity decreases by 21.30% and 22.61%, respectively, after 200 cycles. The maximum whole-life-cycle SOC prediction error is 3.53% with RMSE, MAE, and MAPE values of 3.451%, 2.541%, and 0.074%, respectively, under the complex DST working condition. The improved FF-LSTM modeling method provides an effective reference for the whole-life-cycle SOC prediction in battery system applications

    How does integrative oncology influence patients’ physical and psychosocial outcomes, and what are patients, carers and healthcare professionals’ experiences? An integrative review.

    Objective: To identify the relationship between integrative oncology (IO) services on patients' physical and psychosocial outcomes and to explore the experiences of IO among patients, carers and healthcare professionals. Data sources: This integrative review was reported according to PRISMA guidelines. A search architecture was developed using key words and the following databases were searched: Medline (OVID), EmCare for Nurses (OVID), PsycINFO (OVID); AMED (OVID), CINAHL (EBSCO), Pubmed, the Cochrane Library (CCRT and CDSR) controlled trials databases and ANZ CTR. All articles were assessed according to a pre-determined selection criterion. 426 articles were assessed and 18 were included (4 qualitative, 9 quantitative and 5 mixed methods). Conclusion: Patients reported a reduction in some cancer related symptoms and treatment related side effects. Positive psychosocial impacts were reported such as an increased ability to cope with their cancer diagnosis and treatment. The experiences of healthcare professionals highlighted the importance of a collaborative approach among the Multi-Disciplinary Team (MDT), ongoing education and research to ensure Complementary Integrative Therapies (CIT) were evidence-based. Implications for nursing practice: The provision of IO impacts positively on patients' self-reported physical and emotional wellbeing and quality of life at all stages of their cancer experience. Patients reported that IO supported their engagement in their own health and wellbeing by increasing feelings of control and empowerment. However, to successfully integrate CIT with conventional cancer treatments it is imperative that cancer centres adopt a collaborative and evidence-based informed approach to CIT

    HK was a solo exhibition commissioned by Tramway, Glasgow. The central component of the exhibition was the words HEROIN KILLS presented as six-metre high sculptural forms. This word-sculpture was situated within both the context of Glasgow, as a city with a reputation for heroin abuse, and the context of Tramway, as a gallery with a reputation for international contemporary art. As such, HK revealed assumptions behind accepted notions of socially engaged art practice, questioning who such art projects are for and how they are expected to function. The Tramway commission was the starting point for the ongoing HK project in which the letters HEROIN KILLS have been re-presented in different forms and contexts. HK necklace commissioned for the Scottish presentation at the 2003 Venice Biennale. transformed the word-sculpture into an item of jewellery worn by a number of invited hosts during the opening week of the Biennale

    This watercolour is a response to the changing weather patterns experienced by Aberdeen in recent years, with storm force winds causing havoc. David Henderson is the recipient of this year's David Gluck Memorial Award for this work, which was exhibited at the Bankside Gallery, London, as part of the Royal Watercolour Society Contemporary Watercolour Competition. The competition aims to encourage innovation and experimentation in water-based painting, and provides professional artists with an established and internationally recognised platform on which they can exhibit their work

    The impact of caring for family members with mental illnesses on the caregiver: a scoping review.

    A large amount of multidisciplinary, qualitative and quantitative research suggests that providing care for family members with mental health illnesses can have both positive and negative effects on the carers' wellbeing. However, to date a comprehensive overview and synthesis of literature that compares and contrasts positive and negative effects of family-caregiving on the carer is missing. To address this gap, this scoping review examines the effects of family-caregiving on carers' wellbeing. A Boolean search generated a total of 92 relevant articles that were included in the analysis. The results suggest that, to understand the effects of family-caregiving on the carer's mental and physical wellbeing, it is necessary to take a combination of situational and sociodemographic characteristics into consideration. Elderly, female, spousal-carers and primary-carers may be a group that is at risk of suffering from a lack of positive mental and physical wellbeing as a result of caring. However, the negative effects of caregiving can be balanced by extraversion, social support, and religious or spiritual beliefs. Therefore, future interventions that aim to promote family caregivers' wellbeing may need to take personality, particular circumstances, and cultural and personal beliefs into consideration

    This painting was exhibited at Fly 2016, 3-27 December 2016 at the Royal Scottish Academy building, Edinburgh. This work was driven by theories around semiotics and ideas around interpretation through the depiction of two distinct objects, drawing comparisons whilst acknowledging their separate identities

    The "Fired Up" event on the 30th October 2022 was the first communal firing of the on-campus wood-fired kiln that had been jointly constructed by both staff and students. The works resulting from this firing were then presented at the "Passing the Torch" exhibition, alongside older ceramics from the RGU Art and Heritage Collections. The aim of the exhibition was to facilitate reflection on the development of studio ceramics at Gray's School of Art (RGU). The event demonstrated a continuation of the legacy inherited from earlier ceramic practitioners whose works are held by the RGU Art and Heritage Collections, while also exploring new interests and ideas. After the end of the exhibition, individual items were later displayed elsewhere around the RGU campus as well. The exhibition was organised and curated by Kevin Morris in collaboration with staff from the RGU Art and Heritage Collections

    Our presentation builds on the Happy Hour webinar that was initiated when teaching the 2020/21 Year 1 LLB cohort, who joined their course as online (rather than in-person) students. In order to have a regular, timetabled engagement opportunity for the whole cohort, we introduced the Friday afternoon Contract Law Happy Hour. It gave the teacher an opportunity to look back on the week, feedback on tutorials and lecture matter, as well as setting the scene for the coming week. There was plenty of opportunity for student questions, some light relief (puzzles with naff prizes up for grabs), as well as regular guest speakers (study skills and support; alumni; "meet the author"; etc.). We would like to discuss how we have taken the Happy Hour forward in respect of other in-person law modules, and how these events can be a real game-changer for online-only students, who have considerably fewer direct contact opportunities compared to their in-person peers. We would also like to share advice on possible Happy Hour activities/programmes, and highlight this as a potentially student-led or partnership activity from a very early stage of a course
