Authors: Cai Jingxin
Published: August 2024

This paper applies the theory of cultural memory, proposed by Jan Assmann, to the study of the Chinese classical novel A Dream of Red Mansions. The first part of this paper introduces the historical development of Cultural Memory theory and its features. In the second part of the paper, it applies Cultural Memory theory to the narrative structure and novel characters research of A Dream of Red Mansions. Through analysis, the complexity and inherent contradictions in the narrative structure of A Dream of Red Mansions provide evidence for the hypothesis that A Dream of Red Mansions is a combination of Mirror for The Romantic and The Story of Stone. A Dream of Red Mansions may have more than one author, besides Cao Xueqin, another author is Cao Xueqin's elder, who experienced the rise and fall of the Cao family firsthand. This also explains the contradictions in the character images in A Dream of Red Mansions, especially the persona of Jia Baoyu, which consisted of the authors' life experience and ideal personality.

Published: August 2024

This study addresses the optimization of heliostats for tower-based solar thermal power plants, crucial for carbon neutrality. Initial work establishes solar position and DNI for heliostat efficiency assessment. Analytical geometry and matrix transformations are used to calculate efficiencies, achieving average annual values of 0.7338 for optical, 0.6797 for cosine, 0.8775 for shading, and 0.8983 for truncation, leading to a 294.6007 MW thermal output and 0.3908 MW per square meter. A multi-objective optimization model, employing a particle swarm algorithm, is used to determine an optimal heliostat arrangement with a circular configuration around the tower, resulting in a total of 2650 heliostats over 9540 sq m of reflectivity. Finally, we optimize the size and height of heliostats to reduce shadows, enabling 1546 heliostats to cover a parabolic distribution of 55656 sq m. This study combines mathematical precision with computational techniques, greatly improving the solar energy conversion efficiency of heliostats and promoting the development of clean energy technology.
Influences of strains and environment conditions on lipid A: A case study of Francisella
Authors: Tian Cunxin
Published: August 2024

Tularemia is a zoonosis caused by gram-negative bacteria Francisella tularensis, which has LPS in outer membrane. Lipid A is the most conservative part in LPS and is important for LPS function of bacteria survival and host immune response stimulation. For a certain strain, the lipid A structure is unique, but can also influenced by different environmental conditions. The mechanisms of how lipid A synthesis and modification changes will affect immune mechanism still remain many questions. This article briefly introduces the enzymes participating general lipid A synthesis process. F. novicida, as a specific example, has differences in lipid A-related enzymes from those of ordinary bacteria. Lipid A structure and content can be regulated by some environment conditions like temperature differences between environment and host cells. The structure of lipid A determines its function, so bacterial virulence is various. Some F. novicida knockout mutants have no ability to stimulate immune response in host cells and have lower toxicity than wild-type strains. In therapy, modified lipid A is used as immune adjuvant and some lipid A mutant strains can be vaccines to protect animals against lethal Francisella strain infection. A deeper understanding of Francisella lipid A structure, regulation and immune mechanisms helps to prevent and treat tularemia disease. In future research, more enzymes affecting characteristics of lipid A or the whole LPS can be further studied. More effective vaccines and drug design relies on a better understanding of pathogenic mechanisms.

Published: August 2024

This research provides a transnational analysis of the environmental concerns embedded within the ESG (Environmental, Social, and Governance) information disclosure practices of listed companies in China and the United States. By examining 10 representative firms from each country, the study aims to highlight the variances in environmental awareness and subsequent actions undertaken by entities in these two major economies. However, as some argue, Nonpecuniary factors, such as ESG considerations, should never take precedence over investment returns, risk or lowering fees. Despite this perspective, our investigation adopts a cross-border lens, offering a more holistic perspective. The primary methodological tools involve evaluating ESG report ratings based on MSCI scoring rules and analyzing word frequencies related to environmental topics in Q4 2022 conference call transcripts. Preliminary findings indicate that the predictive effect of the MSCI score does not significantly differ between the two regions, and the attention to environmental issues, as evidenced by word frequencies, is comparable. The study acknowledges limitations arising from the limited dataset and the temporal scope of the research. Nevertheless, this research presents significant implications for international ESG policymaking, potentially guiding more effective strategies to attain Sustainable Development Goals. It also suggests avenues for further research, particularly in expanding the dataset and refining keyword sentiment analysis methodologies.

Published: August 2024

In recent years, with the impact of environmental factors such as global warming, floods and waterlogging disasters have occurred frequently in China. The traditional drainage devices in underground garages have poor water-blocking effects, which can easily result in sewage entering the garage along with vehicles during severe weather or sudden floods. To address the issue of water accumulation outside underground garages, which prevents vehicles from entering, we propose a set of drainage devices for underground garages to complement the shortcomings of existing market products. This device, controlled by an automated intelligent control system, can effectively control each device to achieve automatic water-blocking and drainage operations in underground garages, as well as car washing. During extremely heavy rainfalls, it can completely seal off the garage and enter flood prevention mode to protect vehicles inside from being submerged. Additionally, as the device is semi-underground, it can save a significant amount of above-ground space without affecting surface traffic or existing facilities, demonstrating practicality and having the potential for widespread adoption.

From satellite image to glacier scenery: A novel GlacierPix2Pix model for glacier visualization
Authors: Duan Xinyuan
Published: August 2024

Glacier visualization is critical for studying climate change as glaciers respond rapidly to global warming. It serves as an indicator of environmental changes and provides insights into the magnitude of climate change. Traditional on-site photography faces challenges such as safety hazards, high costs, and tight time constraints. Existing terrain generation models have limitations such as not being capable of using real satellite imagery to control generated terrain and achieving photorealistic image quality. To address these issues, this study introduces GlacierPix2Pix, a novel deep learning model that generates glacier scenery from satellite images. This study uses the Landscape HQ dataset containing 90K terrain images and the USGS Glacier Benchmark dataset containing Digital Elevation Models of 5 different glaciers over many years. This study curates a dataset of over 9K glacier images that can be used in related studies from the LHQ dataset. Glacier contours are extracted from the DEM images and glacier images. Based on the StyleGAN architecture, GlacierPix2Pix comprises a terrain generator, discriminator, and style encoder, and it supports both 2D and 3D methods. The model achieves a Frchet Inception Distance (FID) of 31.90, which surpasses the performance of other similar datadriven methods. It can successfully produce photorealistic glacier images aligned with satellite-derived contours. This research contributes to a better understanding of the urgent issues surrounding climate change, especially its effect on glaciers. Potential applications of this study include demonstrating glacier recession, helping with mapping snow cover and mass balance, and allowing detailed changes in remote locations to be observed.

The review of previous educational taxonomies revealed that although they provide insights into establishing educational objectives and learning outcomes, they still need to address recent changes and challenges in learning processes. To (1) integrate the new realities into the landscape of learning (i.e., Education for sustainable development (ESD), soft skills development, and AI), (2) maintain the classroom as the formal venue for learning, and (3) strengthen the position and role of instructors as facilitators, a new six-category two-fold hierarchy-based taxonomy is proposed (AlAfnan Taxonomy): (1) Knowledge and Comprehension, (2) Synthesis and Evaluation, (3) Ethical and Moral Reasoning, (4) Application and Strategic Thinking, (5) Creativity and Innovation, and (6) Lifelong Learning and Adaptability. The taxonomy begins with foundational levels of ‘Knowledge and Comprehension’ stressing the importance of understanding fundamental realities and concepts within specific fields. Then, it addresses the importance of ‘Synthesis and Evaluation’ as essential and crucial skills for navigating an information-rich world. ‘Ethical and Moral Reasoning’ highlights the significance of ethical decision-making, moral frameworks, and culture-based diversity. Further, the taxonomy introduces ‘Application and Strategic Thinking’, emphasizing the practical use of knowledge in real-world scenarios and the ability to devise long-term plans. ‘Creativity and Innovation’ are essential drivers of progress in an era characterized by rapid technological advancements encouraging learners to explore novel solutions and approaches. Lastly, ‘Lifelong Learning and Adaptability’ underscores the necessity of continuous learning and flexibility in response to evolving circumstances, ensuring students and graduates remain competitive and relevant throughout their lives. By nurturing a multifaceted skill set encompassing critical thinking, ethical awareness, practical application, creativity, and adaptability, this taxonomy aims to equip learners with the necessary tools to excel in a dynamic and complex world, making it indispensable for modern education.

We aim to understand (a) the emotional support given to online learners and (b) the effectiveness of emotional support in online teaching and learning environments. The review shows that the emotional support given to online learners includes empathy, understanding, motivation, and encouragement. These verbal and nonverbal emotional supports are mainly from teachers, family members, and peers as well as some online agents or applications. Most of the emotional supports influence online learners’ performance and have a favorable impact on their emotional states. The systematic review shows that there has been little research on technology-based emotional support and synchronous teaching and learning environments. We propose that more research should be carried out in these areas.

Renal involvement is one of the main causes of morbidity and mortality in patients with Systemic Lupus Erythematous. Lupus Nephropathy should be detected early. Albuminuria may be the only finding in the early stage of kidney disease. An observational, descriptive and retrospective study was carried out to determine the presence of Albuminuria (> 30 mg/24 h) in 60 patients with SLE who were admitted to the Rheumatology Service of the “10 de Octubre” Surgical Clinical Hospital, between October 2013 and September 2014. Albuminuria was observed to increase with increasingly pronounced drops in Glomerular Filtration (predicted according to the equation used in the MDRD Study). A significant statistical association was also obtained between albuminuria and disease evolution time: the longer the disease evolution time, the greater the albuminuria observed. Albuminuria is frequent in patients with SLE, its values being directly proportional to the time of evolution of the disease. This did not occur with the Glomerular Filtration, which remained relatively constant for any time of disease evolution.
Individual and institutional perspectives on barriers to progression to higher education for students with English as an additional language

Almost one in five students in UK schools are recorded as speaking English as an additional language (EAL), a label which encompasses a hugely diverse group of students in terms of their first language(s), educational background, socio-economic status and attainment profiles. A growing
body of evidence suggests that attainment gaps between EAL students and their English-as-first-language peers decrease substantially as they progress through their schooling. In spite of this, in some areas EAL students remain relatively less likely to continue with their studies beyond the
age of 16. There is therefore a pressing need to further explore the factors which influence choices made by this particular group when considering progression to higher education. To this end, an exploratory, qualitative study was conducted in three secondary level institutions in a large
city in the North of England, each with a high proportion of EAL students. Group interviews were conducted with a total of 52 staff and EAL students. This paper presents key findings which relate to sources of information and support for EAL students and identifies particular barriers to higher
education for students, institutions and parents. We conclude with several practical recommendations for widening participation.
Chunked Experiential Learning – an innovative teaching methodology for a modern, diverse classroom

The focus on how we teach widening participation students needs to change and the call from the Office for Students (OfS) to create Access and Participation Plans in 2018 was a much needed one. Between 2017 and 2020 St Patrick's College, London redesigned its learning and teaching methodologies
to create a unique learning experience for non-traditional students which is known as Chunked Experiential Learning. This approach is student-centred, is designed to build both knowledge and skills within students, and encapsulates several key areas which drive towards student success;
chunks of learning to avoid distraction or boredom, knowledge transference which makes the most appropriate use of a lecturer's knowledge, experiential learning to build skills, confidence and real-world capabilities, assessment practice to provide students with
an understanding of assessment formats – formatively and without pressure – one step at a time, deliberate feedback to ensure that students know how to improve their work and classroom conduct and opportunities for reflection, which builds a personalised, contextual
learning and a rapport with teachers. The methodological approach has demonstrated initial efficacy upon results through vastly increased submission rates, pass rates and student satisfaction responses.
