Authors: Vardhan Singh Harsh , Shahid Mo. , Jain Ashish , Kumar Singhai Akhlesh
Published: October 2024

Breast cancer, a prevalent malignancy affecting women globally, is characterized by the uncontrolled growth of abnormal cells in the breast tissue with various risk factors such as age, genetic predisposition, hormonal influences, and lifestyle choices, early detection remains paramount for effective treatment. Diagnostic modalities, including mammography, ultrasound, and biopsy, play crucial roles in identifying the disease at its nascent stages. Therapeutic approaches for breast cancer encompass a multidisciplinary strategy, incorporating surgery, radiation therapy, chemotherapy, hormonal therapy, and targeted therapies. Surgical interventions, such as lumpectomy or mastectomy, aim to remove the tumour, while radiation therapy targets residual cancer cells. Chemotherapy utilizes cytotoxic drugs to destroy rapidly dividing cancer cells, and hormonal therapies modulate hormone receptor-positive tumours. Targeted therapies, including monoclonal antibodies and small molecule inhibitors, focus on specific molecular pathways implicated in cancer progression. Advancements in precision medicine have led to the development of personalized therapies tailored to individual patients based on genetic and molecular profiling. Immunotherapy, harnessing the body's immune system to combat cancer cells, emerges as a promising frontier in breast cancer treatment. In this review article, we have studied how breast cancer is evolved and how we can cure it together with the therapies involved in the management of breast cancer.

Investigating the Impact of Environmental Education on Improving the Environmental Awareness of Elementary School Students
Authors: Sajad Mohammadian
Published: October 2024

Environmental education programs not only broaden children’s knowledge but also enhance their environmental awareness. This research aims to determine the extent to which environmental education improves the environmental awareness of elementary school students. In addition to reviewing existing studies, this research employs a questionnaire method to gather data. It also examines the effectiveness of using questionnaires to evaluate children’s environmental awareness. The findings indicate that the efforts of environmentalists and school environmental education instructors positively influence children. Students demonstrate a strong connection to nature, their local geography, and the environment. They also gain substantial, accurate information about the environment and its unique characteristics. However, assessing the level of environmental awareness among children solely based on school education programs is challenging. Comparing schools with and without environmental education programs could provide more meaningful insights. This study investigates the impact of environmental education on enhancing primary school students’ environmental awareness through the use of questionnaires. The results reveal that regular exposure to nature, combined with educational programs, positively affects children’s understanding of and commitment to nature conservation.

Wall-models of turbulent flows via scientific multi-agent reinforcement learning
Authors: Bae H. Jane
Published: October 2024

The predictive capabilities of turbulent flow simulations, critical for aerodynamic design and weather prediction, hinge on the choice of turbulence models. The abundance of data from experiments and simulations and the advent of machine learning have provided a boost to turbulence modeling efforts. However, simulations of turbulent flows remain hindered by the inability of heuristics and supervised learning to model the near-wall dynamics. We address this challenge by introducing scientific multi-agent reinforcement learning (SciMARL) for the discovery of wall models for large-eddy simulations (LES). In SciMARL, discretization points act also as cooperating agents that learn to supply the LES closure model. The agents self-learn using limited data and generalize to higher Reynolds numbers in reproducing key flow quantities.
Waveform inversion via reduced order modeling
Authors: Borcea Liliana
Published: October 2024

This talk is concerned with the following inverse problem for the wave equation: Determine the variable wave speed from data gathered by a collection of sensors, which emit probing signals and measure the generated backscattered waves. Inverse backscattering is an interdisciplinary field driven by applications in geophysical exploration, radar imaging, non-destructive evaluation of materials, etc. There are two types of methods:(1) Qualitative (imaging) methods, which address the simpler problem of locating reflective structures in a known host medium. (2) Quantitative methods, also known as velocity estimation. Typically, velocity estimation is formulated as a PDE constrained optimization, where the data are fit in the least squares sense by the wave computed at the search wave speed. The increase in computing power has lead to growing interest in this approach, but there is a fundamental impediment, which manifests especially for high frequency data: The objective function is not convex and has numerous local minima even in the absence of noise. The main goal of the talk is to introduce a novel approach to velocity estimation, based on a reduced order model (ROM) of the wave operator. The ROM is called data driven because it is obtained from the measurements made at the sensors. The mapping between these measurements and the ROM is nonlinear, and yet the ROM can be computed efficiently using methods from numerical linear algebra. More importantly, the ROM can be used to define a better objective function for velocity estimation, so that gradient based optimization can succeed even for a poor initial guess.

The Greater Accra Metropolitan Area of Ghana is experiencing rapid urbanisation at the expense of the environment, with substantial pollution compromising the area's resilience. This article examines the spatial dynamics of pollution from land use in the area and its health-related impacts. Drawing on a desk review of the literature and a transdisciplinary empirical approach, this study employed participatory mapping and qualitative methods of analysis to examine the extent to which the Greater Accra Metropolitan Area is building resilience in the face of increasing environmental pollution induced by land use. The researchers found spatial variations in the phenomenon, i.e. community-specific land-use pollution and general land-use pollution. Community-specific land-use pollution comes from dust and fumes, quarries and sand weaning, historical preservations, and transport corridors. General land-use pollution found across the study area related to dusty areas, noise from markets and churches, contamination of water bodies, solid and liquid waste, as well as excessive spillage of lubricants and carbon monoxide from car engines – all of which poses a threat to human health. Although both local and successive national governments have initiated different actions and platforms to mitigate pollution from land use and its health impacts, Ghana must work harder to build a framework of more sustainable and robust urban resilience.

Published: October 2024

Urban infrastructure encompasses the essential amenities, facilities, and services that make life easy and comfortable for residents within neighbourhoods. The provision of nine basic urban amenities across thirteen neighbourhoods in Minna, and measurement of access to amenities by households are the points of evaluation in this study. A total of 1,134 housing units were sampled using the stratified and systematic random sampling techniques. Data were generated from questionnaires, inspections and enumeration in the study area. Weighted mean scores were computed and indexed to determine overall accessibility to amenities. The location quotient (LQ) was used to estimate the degree of concentration of the amenities, while the Welch adjusted analysis of variance tested for a significant difference in the distribution of urban amenities across neighbourhoods. The adjusted Welch's F ratio was 2.959, which was significant at the 0.05 alpha level, suggesting an uneven distribution of amenities across neighbourhoods in the study area. This study emphasises that government at all levels should prioritise provision and development of amenities and also support efforts by communities regarding basic amenities and services.

Migration pattern of Atlantic salmon smolts Salmo salar L. released at different sites in the River Drammenselv, SE Norway
Authors: Pethon Per , Hansen Lars P.
Published: October 2024

Hatchery-reared smolts of Atlantic salmon Salmo salar L. of the River Drammenselv stock were released at four different sites in the River Drammenselv system; (1) at Gol, (2) at Kaggefoss, (3) at Hellefoss and (4) in the estuary at Svelvik. All smolts were individually tagged with Carlin tags. Based on tag returns the first two months after release, it became evident that the great majority of the smolts descended the river and migrated to sea. The smolts released at Gol descended the river with average speeds between 4.3 and 5.4 km day-1, whereas the smolts released at Hellefoss and Kaggefoss descended on average 13.4 km of the river per day. The speed of descent decreased when the smolts reached the fjord, but seemed to increase when the fish reached the coastal current. This migration pattern is discussed in relation to the current system both in the river, the estuary and the sea.

The impact of calcined mud on the rheological properties of eco-friendly concretes using the equivalent mortar method (CEM)
Authors: Kiboub Mohammed Yacine , Malab Souad , Belaidi Akram Salah Eddine , Takhi Kaouthar
Published: October 2024

In order to harmonise technical and environmental aspects, people today focus not only on concrete's technical characteristics but also on environmental imperatives. Thus, the emphasis is on the development of concrete and cements that offer ecological and sustainable advantages. Commonly, people use various natural materials as cement additives, demonstrating their effectiveness by replacing a significant portion of the cement in the hardened state of concrete. This substitution leads to a substantial and remarkable reduction in carbon dioxide emissions. However, when it comes to the physical properties of the material in its fresh state, challenges may arise. Indeed, the rheological changes induced by these additives may hinder the on-site use of this eco-concrete. The main purpose of this study is to find out how adding minerals to environmentally friendly concrete changes its rheological parameters (yield stress, plastic viscosity) and fresh properties (slump, flow time). We will approach this using the concept of mortar equivalent to concrete (CEM). We developed five formulations of CEM’s by substituting cement with calcined mud (CM) in binary mixing systems at a temperature of 20 °C. The results showed that adding binary cements with calcined mud had a negative effect on the fresh properties and rheological parameters. However, when substitution happens at a low rate, it behaves almost like control mortar (OPC).

Authors: Zhao Yangyi , Tu Zixuan , Chen Siyi
Published: October 2024

With the advent of the digital economy era, data assets play a pivotal role for enterprises. Therefore, this paper selects the data of Chinese A-share listed companies from 2013-2022 to conduct a quantitative study on data assets and explore the impact of enterprises' data assets on their investment efficiency. It is found that data assets significantly contribute to firms' inefficient investment. This finding still holds after the robustness test. Heterogeneity analysis reveals that data assets can promote overinvestment in non-state-owned firms; they contribute more to inefficient investment in growing and declining firms. The mechanism test suggests that data assets promote firms inefficient investment due to promoting firms financing constraints and real earnings management. Therefore, the findings of this paper provide certain clues and suggestions for enterprises to dialectically view data assets to maximize their effectiveness and avoid data bubbles.

Authors: Zhang Songyuan
Published: October 2024

The rapid expansion of high-speed rail (HSR) has become a crucial element of infrastructure, markedly improving regional connectivity and economic integration. This study centers on the Guangzhou-Shenzhen-Hong Kong Express Rail Link (XRL), a pivotal project that connects major cities within the Pearl River Delta (PRD) and links Hong Kong to mainland China. The analysis demonstrates that while the XRL has stimulated economic growth by facilitating inter-regional exchanges, it has also presented challenges to local vulnerable sectors, particularly small and medium-sized enterprises (SMEs). These challenges stem from heightened competition due to industrial agglomeration. To mitigate these effects, the study proposes enhancing regional economic cooperation by establishing specialized economic zones and developing cross-border trade networks. These strategies aim to capitalize on the benefits of the XRL while enabling SMEs to access new markets and boost their competitiveness. The research underscores the importance of strategically leveraging infrastructure projects like the XRL to promote sustainable economic growth, offering a framework for addressing potential drawbacks.

Published: October 2024

The rapid advancement of e-commerce has introduced numerous challenges, particularly regarding the rural-urban divide, marked by disparities in income and resource distribution. Addressing these issues is crucial to ensure sustained growth in this sector. This paper examines the current state of rural e-commerce through secondary data analysis, noting the dichotomy of positive and negative impacts, with a particular focus on Taobao Village as a case study. While existing literature has extensively reviewed the benefits and drawbacks of e-commerce, this paper concentrates on the primary threats and underlying causes affecting rural areas. Notably, the digital divide and skill deficiencies emerge as significant obstacles. The digital divide highlights the gap between those with access to technology and those without, while skill deficiencies refer to the lack of necessary technical skills among rural populations to effectively engage with e-commerce platforms. To address these challenges, the paper proposes several practical solutions. These include increased financial investment in digital infrastructure and targeted training programs to enhance technological skills among rural residents. Additionally, efforts to change attitudes towards technology, particularly among those resistant to electronic devices, are crucial for fostering a more inclusive digital economy. Overall, the paper underscores the need for government intervention to mitigate the potential threats posed by e-commerce, ensuring that the benefits are equitably distributed and the industry continues to flourish.

This essay opens with an in-depth discussion of the growing importance of ESG concepts in modern corporate management and highlights their significant role in promoting long-term corporate value creation. With the increasing global focus on sustainability, ESG concepts have become an integral part of corporate strategic planning and operational decision-making. Next, this article selects the global retail giant Walmart as a case study and uses SWOT analysis and other management tools to analyse in detail how Walmart has effectively constructed and consolidated its competitive advantages in the highly competitive market through the implementation of an active ESG strategy. The article specifically describes Walmart's practices on several ESG dimensions, including but not limited to the implementation of environmental protection measures, active support to the community, the enhancement of employee welfare, and the optimisation of corporate governance structure. In terms of environmental protection, Walmart has significantly reduced the environmental impact of its operations through measures such as reducing carbon emissions, improving energy efficiency and promoting sustainable products. In terms of community support, the company has strengthened its ties with local communities and enhanced its brand image through various community programmes and charitable activities. Employee well-being has been achieved through improved working conditions and career development opportunities, which have not only increased employee satisfaction but also enhanced the company's attractiveness. The article concludes by summarising the important contribution of Walmart's ESG practices to the company's sustainability and long-term competitive advantage and suggests possible future strategic directions and recommendations for Walmart in ESG based on current market trends and company performance. These recommendations are intended to provide valuable references and insights for Walmart and other companies in their future strategic planning and decision-making processes, especially in terms of how to balance economic efficiency and social responsibility to achieve long-term sustainable development. However, due to the limitation of data and the depth of research on Walmart ESG, the article still has limitations.

Published: October 2024

Backpropagation isthe core part of a neural network. This method is used to efficiently train a network using a chain rule that allows differentiation of complex functions. In other words, after each pass through the network, the backpropagation method performs a backward pass to adjust the model parameters, such as weights and biases. This article highlights the importance of using the backpropagation method from the point of view of mathematical formulas for neural networks. The importance of using the backpropaga-tion learning algorithm to calculate the gradient (gradient descent) and the need to use the activation function to minimize the loss function is mathematically described and calculated by formulas, and also proven by calculating the matrix products of vectors for each layer of parameters - weights and biases and applying complex differential equations.
