Electrochemical energy storing performances of printed LaFeO3 coated with PEDOT: PSS for hybrid supercapacitors
Get PDFeveloping advanced smart energy storage devices demanded new functional materials to store energy effectively and deliver power quickly. In this work, we studied the energy-storing performance of perovskite material, lanthanum ferrite (LaFeO3), prepared by the solid-state reaction method. The screen-printed LaFeO3 and graphite electrodes are used to develop hybrid supercapacitors (HSCs) with KOH electrolyte. Varying the sintering temperature of the LaFeO3 perovskite electrode (800 °C, 900 °C, and 1000 °C) leads to changes in the surface and crystalline properties, which impact the electrochemical properties and overall energy-storing performance of the HSC. The surface of the LaFeO3 electrode is modified with organic conducting polymer poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT: PSS), which enhances the energy storage of the HSC. The developed HSC based on LaFeO3, sintered at 1000 °C and surface modified with PEDOT: PSS, exhibited a specific capacitance of 12.007 mF∙cm−2 at a current density of 0.075 mA∙cm−2. This value is two times higher than (5.874 mF∙cm−2) without the surface modification of LaFeO3 at 1000 °C. This study provides valuable insights into the electrochemical performances of the ABO3 perovskite (LaFeO3) electrodes for the next generation of portable energy storage devices
Micro-mechanisms of digitalization-driven financing for renewable energy: Growing capital pools and shifting flows
No full textRecent facts from China suggest that the advancement of digitalization is altering the market expectations regarding renewable energy. Limited studies have offered evidence encompassing the stock effect of digitalization that enhanced corporate financing and the flow effect that initiated speculative behavior. However, a comprehensive discourse remains insufficient. This paper investigates the synergetic effects of digitalization's stock and flow on renewable energy financing, employing the business data of all listed companies in China from 2003 to 2023. The results demonstrate that: (1) Digitalization's stock has expanded the potential fund pool for renewable energy financing, yet it is challenging to influence the flow of funds; digitalization's flow has triggered a flood of funds into the renewable energy industry, but this relies on the new investors attracted by the stock. (2) The synergetic effect governs the systematic influence of digitalization on renewable energy financing and mitigates the measurement bias when considering only a single effect. (3) We further contemplate the indirect effects of renewable energy market expansion, technological progress, and global energy market fluctuations, alleviating concerns regarding the omitted variable bias. The results of the differential regression and generalized method of moments also indicate the robustness of the conclusion
MTFDN: An image copy‐move forgery detection method based on multi‐task learning
No full textImage copy-move forgery, where an image region is copied and pasted within the same image, is a simple yet widely employed manipulation. In this paper, we rethink copy-move forgery detection from the perspective of multi-task learning and summarize two characteristics of this problem: (1) Homology and (2) Manipulated traces. Consequently, we propose a multi-task forgery detection network (MTFDN) for image copy-move forgery localization and source/target distinguishment. The network consists of a hard-parameter sharing feature extractor, global forged homology detection (GFHD) and local manipulated trace detection (LMTD) modules. The difference of feature distribution between the GFHD module and the LMTD module is significantly reduced by sharing parameters. Experimental results on several benchmark copy-move forgery datasets demonstrate the effectiveness of our proposed MTFDN

Beyond the Monoplot: How to Write Unconventional Films (and Why We Should)
No full textThis book provides a toolkit for unconventional practice-a comprehensive list of unconventional story shapes and the meanings they create, with accompanying case studies, including: one-act structure; two-act structure; passive protagonists; untimely death of the protagonist, and more.Formed from Aristotelian principles and a three-act shape brought to Hollywood by Broadway playwrights after the advent of sync sound, Conventional Monoplot has come to dominate screen storytelling practice throughout the Western world. For the experimental, rule-suspicious, unconventional screenwriter, alternative storytelling models are available. Beyond the Monoplot offers screenwriters and screenwriting students a new way of approaching and quantifying conventional practice, whilst equipping them with the skills and tools to subvert convention and expectation in dynamic and innovative ways.Where the revolutionary New Hollywood period of the '60s and '70s saw strikingly iconoclastic, original, rule-breaking narratives attracting enormous audiences and making indelible cultural imprints, today's most widely seen films stick rigidly to the Conventional Monoplot model. Shaped and solidified by best-selling screenwriting handbooks of the '80s and 90s, this model proved incredibly useful for a rapidly industrialising consumerist approach to screen entertainment, pushing unconventional and innovative storytelling practices to the cultural fringe. Whilst bold, daring films are still made, their impact is muted: Moonlight, despite winning Best Picture, was only the 92nd highest grossing film of its year. And whilst great strides are made towards diversity and representation, story shapes remain cloistered within a consumerist and highly conventionalised form, against which this book pushes back
Assessing Self-Reported Prolonged Grief Disorder with ‘Clinical Checks’: A Proof of Principle Study
Get PDFPsychological assessment is commonly conducted using either self-report measures or clinical interviews; the former are quick and easy to administer, and the later are more time consuming and require training. Self-report measures have been criticised for producing higher estimates of symptom and disorder presence relative to clinical interviews, with the assumption being that self-report measures are prone to Type 1 errors. Here, we introduce the use of ‘clinical checks’ within an existing self-report measure. These are brief supplementary questions intended to clarify and confirm initial responses, similar to what occurs in a clinical interview. Clinical checks were developed for the items of the International Grief Questionnaire (IGQ), a self-report measure of ICD-11 prolonged grief disorder (PGD). Data were collected as part of a community survey of mental health in Ukraine. Individual symptom endorsements for the IGQ significantly decreased with the use of clinical checks, and the percentage of the sample that met the ICD-11 diagnostic requirements for PGD fell from 13.6% to 10.2%, representing a 24.8% reduction of cases. The value and potential broader application of clinical checks are discussed
How Does the Digital Economy Affect the Green Transition: The Role of Industrial Intelligence and E-Commerce
No full textAs a new economic form, the digital economy (DE) significantly impacts green development. However, the impact of the DE on green total factor productivity (GTFP) remains controversial. A two-way fixed effect model is constructed to explore the impact of DE on green development. It is found that (1) there is a U-shaped relationship rather than a positive relationship between DE and GTFP. (2) Industrial intelligence and e-commerce are essential for DE to affect GTFP. (3) The DE affects GTFP mainly by promoting efficiency progress rather than technological progress. In addition, in regions where government attention to the DE is higher than others, the DE substantially contributes to GTFP. The potential of integrating the DE and the real economy needs to be further tapped. This paper presents pertinent policy suggestions and provides new empirical evidence and valuable reference for promoting green development
Enhancing graduate employability – exploring the influence of experiential simulation learning on life skill development
Get PDFSkills and knowledge which increase the likelihood of university graduates finding employment is an increasingly important factor for higher education institutions. Even though subject matter expertise remains a primary objective, supporting students to build life skills that are desired by employers is essential to enhance graduate employability. Firstly, we draw on consultive interviews with 11 graduate recruiters to build a life skill ability scale. Through these interviews, we identify two constructs worth measuring (resilience and adaptability) not yet represented in extant life skill ability scales. Thereby contributing to life skills measures and their link to graduate employability. Secondly, this paper explores the influence of a team-based business simulation on the development of life skills at two higher education institutions in the UK for first- and fourth-year undergraduate students. Through a pre-survey and post-survey, this paper empirically finds that experiential learning by means of a team-based business simulation has an overwhelmingly positive influence on first-year students’ self-assessed life skill development as well as their course-specific subject matter expertise. Yet, the findings show less significant results for fourth-year students. This contributes to our understanding of business simulations as a pedagogical practice and its benefits for students beyond their education
The relationship between frailty syndrome and quality of life in patients with hypertension: a multidimensional analysis
Get PDFBackground: Hypertension is a common condition among the elderly and is frequently accompanied by frailty syndrome (FS). The coexistence of hypertension and FS poses significant challenges in patient management and negatively impacts the quality of life (QoL). This study aimed to analyze the relationship between FS and QoL in elderly patients with suspected hypertension. Methods: A cross-sectional study was conducted involving 201 patients aged 65 years or older, referred to a Hypertension Clinic for diagnostic evaluation. Frailty was assessed using the Tilburg Frailty Indicator (TFI), and QoL was evaluated with the World Health Organization Quality of Life Instrument (WHOQOL-BREF). Sociodemographic and clinical data were collected, and statistical analyses were performed to identify correlations between FS and QoL. Results: The study found that 79.60% of the patients were identified as frail (TFI ≥ 5). FS was significantly negatively correlated with all domains of QoL, including physical health (r = -0.634, p < 0.001), psychological health (r = -0.675, p < 0.001), social relationships (r = -0.528, p < 0.001), and environmental factors (r = -0.626, p < 0.001). Multivariate analysis revealed that physical (β = -0.091, p < 0.001) and psychological components of FS (β = -0.128, p = 0.016), as well as age (β = -0.022, p = 0.004), were significant predictors of lower QoL scores. Loneliness (β = -0.235, p = 0.049) was also a significant predictor of lower QoL. Conclusions: The study demonstrated a strong association between FS and reduced QoL in elderly hypertensive patients, emphasizing the need for comprehensive assessments and personalized management strategies. Routine evaluation of frailty and the implementation of targeted interventions aimed at improving physical, psychological, and social well-being could substantially enhance QoL in this vulnerable population. Clinical trial number: Not applicable
