Authors: Wei Zheng , Jiang Yusan , Li Xingjun , Zhao Minghui , Wu Jianzhang , Yan Enfeng
Published: December 2023

Objective: This study is to determine the main parameters influencing the storage of shelled corn with slightly high moisture content (MC) so that its quality can be maintained. Methods: The intergranular air properties and chemical changes was determined in 4,169 tonnes of shelled corn bulk with an average MC of 15.3% and a height of 5m, which was stored for 90 days in a large warehouse in Shandong Province, China, from winter to early spring. The intergranular air property parameters were calculated with self-compiled software. Results: Fans were used to achieve temperature-equalizing aeration at a low rate (5.87m3/h/t) after warehousing, which decreased the bulk temperature from 6.8 to 4.7℃. Afterwards, with the increase in ambient temperature, the surface-layer grain temperature increased drastically, while that of the bottom layer increased slowly and those of the middle layers increased even more slowly. The minimum and mean cumulative dry-bulb, wet-bulb and dew-point temperatures (DPT) increased in the order of middle layer˂ bottom layer˂ surface layer. Free fatty acid content, kernel breakage percentage, water adsorption rate, gelatinization enthalpy, peak enthalpy, and fatty acid profiles (C16:0, C18:0, C18:3n3, C20:0 and C20:1) were significantly related to the cumulative intergranular air properties of grain bulk. Conclusion: The above physio-chemical parameters were significantly influenced by the minimum and mean cumulative values of relative humidity, Humidity ratio and DPT in the bulk, and can be used to evaluate the quality of shelled corn with slightly high MC during short-term storage.
The Rise in Economic Inequality in India in Recent Years
Authors: Aggarwal Vibha
Published: December 2023

India's economy is among the fastest expanding in the world, yet it also ranks among the most unequal. Throughout the past thirty years, inequality has been steadily increasing in the country. A significant portion of the wealth generated by crony capitalism and inheritance has been monopolized by the wealthiest. Their rate of wealth accumulation is significantly exceeded that of the impoverished, who struggle to make ends meet and obtain adequate healthcare and education. In the paper we try to scrutinize the trends in income and wealth inequality in India and also examine the impact of Covid-19 pandemic on economic inequality in the nation. Some policy suggestions are made as India navigates the road to recovery to alleviate the gaps posed by the extraordinary difficulties presented by COVID-19 and promote a more resilient and equitable economic environment in post-pandemic India.

Published: December 2023

Introdução: A Pneumonia Associada à Ventilação Mecânica é uma das Infecções Relacionadas à Assistência à Saúde mais comuns, sendo Pseudomonas aeruginosa um dos agentes etiológicos mais relacionados a este processo infeccioso. A diversidade de mecanismos de resistência aos antibióticos contribui para o desenvolvimento de linhagens multirresistentes e torna os antibióticos convencionais ineficazes.  Objetivo: Avaliar a prevalência de bactérias isoladas de amostras de aspirado traqueal de pacientes hospitalizados com foco em Pseudomonas aeruginosa e no seu perfil de suscetibilidade aos antimicrobianos. Material e Métodos: Trata-se de um estudo descritivo, retrospectivo realizado através da coleta de dados de resultados de culturas de aspirado traqueal de pacientes internados em um hospital universitário localizado no município de Juiz de Fora, Minas Gerais, Brasil, no período de janeiro de 2020 a dezembro de 2021. Resultados: Entre as amostras de aspirado traqueal submetidas a cultura nos anos de 2020 e 2021, houve crescimento bacteriano em 532 amostras. As três espécies bacterianas mais isoladas foram: Acinetobacter baumanni com 163 (30,63%), Pseudomonas aeruginosa com 143 (26,87%) e Klebsiella pneumoniae com 60 (11,27%). Em relação ao perfil de sensibilidade aos antimicrobianos das linhagens isoladas de Pseudomonas aeruginosa, observou-se resistência aos seguintes antimicrobianos: 44,75% ao meropenem; 53,14% ao imipenem; 15,38% a amicacina; 28,67% a gentamicina; 16,78% a piperacilina + tazobactam; 34,96% ao aztreonam; 27,97% a ceftazidima; e 37,76% a levofloxacino. Ressalta-se que 59% dos isolados de Pseudomonas aeruginosa foram considerados multidroga resistente. Conclusão: Acinetobacter baumanni e Pseudomonas aeruginosa foram as bactérias mais isolada de amostras clínicas de aspirado traqueal de pacientes hospitalizados. A amicacina foi o antimicrobiano que apresentou maior sensibilidade frente aos isolados de Pseudomonas aeruginosa. A presença de Pseudomonas aeruginosa multidroga resistente em hospitais corresponde a um grave problema de saúde pública, tornando necessária a implementação de medidas de controle e prevenção referentes a disseminação desta linhagem bacteriana.

Authors: Zou Tianchang , Li Muzi , Li Xinyue
Published: December 2023

Wordle is a popular game, and I did a detailed analysis of the Wordle dataset provided by the New York Times to better understand the game. First, we proposed a lifetime change model to describe the number of reported results over time, and through analysis we found that the property of "whether a word contains repeated letters" affects the fraction percentage of the difficult pattern. We then constructed a GloVe-LBP neural network to predict the reported percentage of a given solution and performed a detailed analysis of the model confidence, loss function, training adequacy, and generalization ability. Next, we constructed a K-Means and z-score classification model to classify the difficulty of words, through which the "EERIE" difficulty level was level 5. The relationship between the number of reported results and the number of difficult patterns in the data set was concluded and analyzed.

Authors: Chen Yuyao , Li Xiping , Jiang Aiai
Published: December 2023

The change process of plant communities is an important issue involving botany, environmental science and system science. This paper mainly studies the state changes of plant communities under irregular weather cycles, and establishes a dynamic model of species interaction based on Lotka-Volterra equations. The Euler method, statistical analysis are used to solve the problem. we extend the basic Lotka-Volterra model to the generalized Lotka-Volterra model, which can describe the change of a community with multiple species. Based on this, by introducing parameters such as drought intensity, species sensitivity to drought, pollution level and habitat reduction into the equations, a model for predicting the change of plant community status under the influence of irregular weather cycles is obtained. The statistical method is creatively used to do Sensitivity analysis for the model. The results show that: (1) pollution and habitat reduction do not affect the advantages of highly drought-resistant plants, but extend the gain range of species number on plant community stability. (2) the influence of some negative factors on the gain interval is the comprehensive result of the influence of two opposite factors, competition intensity and species diversity.
Enhanced protein function prediction by fusion embedding based on protein language models
Authors: Wang Yang
Published: December 2023

Natural language models can accomplish non-natural language tasks such as protein prediction, but the actual prediction effect is low and occupies large computational resources. In this paper, a fusion embedding model is proposed to improve the prediction effect of the model and reduce the computational cost of the model by fusing information of different dimensions. The paper is validated by the downstream task of protein function prediction, which provides a reference for solving practical tasks using fusion embedding methods.

Diabetes management is complex and multifarious as it contains numerous contexts including blood pressure and blood glucose monitoring, decision on daily insulin dose, strict diet, cautious planned exercises, and frequent clinical consultations. On the other hand, diabetes care requires patients’ major efforts on self-management and initiative. Moreover, there are enormous amounts of data transition and sharing of electronic medical records, insulin pumps, sensors, glucometers, and such between patients with diabetes and healthcare professionals. Various digital health technologies have hence been developed to assist and supervise patients’ daily diabetes management, in order to improve their medical adherence. Especially after the outbreak of COVID-19 pandemic, the era has witnessed a sudden growth of trend in applying digital health techniques in diabetes management. Increasingly, more patients with diabetes are using wearable or other technological devices to support diabetes self-management. Thus, this review article aims at conducting a horizontal comparison of current diabetes digital management in an international perspective, in order to provide some constructive suggestions on future research directions or references for improving diabetes tele-management in China in the post-pandemic era.
Integration and Challenges of Excipients with Pharmacological Efficacy
Authors: Zhang Haosheng
Published: December 2023

Excipients are extra compounds that are included with the primary active ingredients in medicinal products. They are essential in enhancing the stability and accessibility of medications. Although excipients are a common component of daily life, incorporating them with pharmaceuticals still offers some difficulties. Although there are many different kinds of excipients, not all of them can completely match a medicine. Excipients will be used in diverse ways as carriers as a result of the various pharmaceutical production methods, which will modify the excipients that are chosen. Excipients often engage in the body's absorption and metabolism just like active pharmaceutical substances do. Different excipients have been tested in vitro and in vivo by researchers. They matched in vitro activity tests of 25 excipients to clinical safety tests. As a result, they discovered an extra 109 activities. Many individuals now understand that considering excipient toxicity is important. Researchers integrated it with cell models in animal trials and discovered that five excipients can predict the fingerprint of systemic toxicity. Additional research is required on the exposure of seven excipients, including thimerosal intestine exposure. Effect and risk ratio are two factors that are taken into consideration while assessing an excipient's safety. When examining a patient's response to a medication and how it varies, drug researchers may come across a range of circumstances. This article's objectives are to introduce the idea of excipients, examine some typical excipient usage instances, and provide an overview of excipient use in pharmaceuticals. Drug development is a dynamic process that is always changing. Although excipients have been employed in therapeutic settings, there are still a great deal of undiscovered excipients that require further study, analysis, and summarization.
Single-Cell RNA Sequencing: A Deep Dive into The Cellular Landscape and Interactions in Hepatocellular Carcinoma
Authors: Miao Kejia , Liu Xudong
Published: December 2023

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths worldwide, with its progression highly influenced by the cellular interplay within the tumor microenvironment that is underexplored. Aiming to bridge this gap, our study utilizes single-cell RNA sequencing (scRNA-seq) to examine the cellular heterogeneity of HCC and investigate the roles of distinct cell populations. scRNA-seq was performed on eight DEN mice HCC samples, followed by bioinformatic analysis with Seurat package. Nine distinct cell populations were identified, with three unique macrophage populations suggestive of their role as tumor-associated macrophages (TAMs). The detected endothelial cells and pericytes hint at ongoing neoangiogenesis, with implications that endothelial cells might function as tumor-associated endothelial cells (TECs) and pericytes as carcinoma-associated fibroblasts (CAFs). Our findings provide insights into the potential roles of various cell populations in the HCC tumor microenvironment, which paves the way for developing novel therapies. These postulations, while offering a deeper understanding of HCC's cellular landscape, necessitate experimental validation for confirmation.
Progress in Molecular Genetic Breeding of Rice Spike Development
Authors: Wang Yizhen
Published: December 2023

Rice (Oryza sativa L.) is one of the most important food crops in the world, belonging to the Gramineae family of the basal monocotyledonous group of angiosperms. It has become a model plant for Gramineae and even monocotyledons. Rice flower/spike is the first major element of rice yield composition, and the study of the molecular genetic mechanism of flower/spike development in rice is of great significance in guiding the yield improvement of rice and other gramineous crops. However, there were fewer reviews on rice flower/spike development. This paper summarized the related gene regulation of rice spike development, gene editing, the genetic regulatory network of spike development, and the application of high-yield breeding. This will provide a theoretical basis and technical support for the research on the molecular genetic improvement of rice in flower/spike.

Authors: He Lanhuayu
Published: December 2023

Along with the acceleration of urbanization and industrialization, the problem of environmental pollution in China has become increasingly prominent, putting forward new requirements for city construction. In 2012, the Chinese government proposed to build smart cities. This policy not only strengthened the urban informatization construction, but also provided valid solutions for China's environmental governance. However, there is little literature about the effect of smart city construction on pollution emission. Based on this, this paper used panel data from 284 cities in China during 2003–2019 to evaluate the effect of smart city construction on SO2 emissions by constructing a multi-period DID model. The findings are as follows: (1) The smart city construction could significantly reduce the emission of SO2 and the conclusion was robust. (2) There was a temporal hysteresis in the response of SO2 emissions to the smart city construction, and SO2 emissions began to decrease significantly in the third year after smart city construction. (3) Industrialization could significantly increase SO2 emissions, while opening up to the outside world and the concentration of population could significantly decrease SO2 emissions.

Authors: Lv Junyi , Xie Yuan , Yan Zixiang , Wang Tong
Published: December 2023

In recent years, the rapid development of industrialisation has led to serious light pollution problems . In order to measure the degree of regional light pollution, firstly, this paper divides light pollution into three parts: ecological light pollution (Eco), daylight pollution (Dai) and decorative light pollution (Dec), selects nine secondary indicators, assigns a value to each indicator using the entropy weight method (EWM), and the three main indicators are 0.2484, 0.3569 and 0.3947, and combines with the tosis to establish a comprehensive evaluation model. In addition, considering the importance of necessary light, we added three metrics to the original metrics to optimise the model to ensure better safety and comfort.Finally, Applying the model to four specific areas, namely urban, rural, suburban and protected areas, to measure the specific pollution level of the region. Domestic research on light pollution is mainly qualitative research, this paper comprehensively considers the necessity of appropriate amount of light and the harm of excessive light, and proposes a comprehensive evaluation model of light pollution based on the entropy weight method to quantitatively analyse the degree of light pollution. This paper provides a new perspective for light pollution prevention and control.
Study on the influence of weathering process on the chemical composition of ancient glass based on CLR
Authors: Li Gen , Ba Ninghua , Li Peiji
Published: December 2023

The aim of this study was to investigate the effects of weathering processes on the chemical composition of high-potassium and lead-barium glass. First, correlation and difference analyses were performed on the surface weathering of glass artifacts in relation to their glass type, ornaments, and color, all of which showed that glass type had a significant effect on surface weathering, and that lead-barium glass was more susceptible to weathering than high-potassium glass. Then, the complex and difficult compositional data of glass artifacts were transformed into simple and easy to handle CLR data by central logarithmic ratio transformation (CLR), and independent sample t-tests or Satterthwaite approximate t-tests were performed for each chemical composition content of high-potassium glass and lead-barium glass before and after weathering, respectively, to identify the influence of weathering process on the chemical composition content of the two glasses. Finally, the chemical composition content of the weathered glass artifacts before weathering was predicted from their chemical composition content after weathering by distribution matching method and transformed back to the compositional data by CLR inversion.
Research on the Impact of Urban Environmental Pollution and Countermeasures
Authors: Huang Chenhao
Published: December 2023

The process of economic building and growth, as well as human production and living, results in a significant amount of pollutants and trash generation as urban populations become denser. Urban environments can only self-purify so much before being severely polluted and degraded, which has a negative impact on both human health and urban landscape. The contradictions between population, resources, environment, and economic development have become more pronounced with the speeding up of industrialization, and the quality of the urban environment has also shown a trend of gradual deterioration, which severely limits the sustainable growth of cities. Due to this, the issue of urban environmental pollution has drawn increasing attention, and a growing number of urban environmental pollution management methods have been implemented. In this context, this paper briefly introduces the types of urban environmental pollution such as air pollution, water pollution, etc., and mainly introduces the impact of various pollutions, among which the impact on human health is the most serious. And pointed out various measures to control pollution. Finally, this paper emphasizes that the current methods of controlling urban environmental pollution are not perfect, and more experimental research is needed to obtain more efficient treatment methods, so that urban environmental pollution can be controlled more efficiently in the future.
Analysis and Research on the Development of Geothermal Energy and Future Development Trend
Authors: Yu Jian
Published: December 2023

Scientists and engineers from all over the world have acknowledged the significance of employing environmentally friendly energy to replace fossil fuels in manufacturing as global warming has gotten worse over the past century. Geothermal energy, which is a form of subsurface energy that is stored as heat and gas, is one of many sustainable energy sources. There are currently three popular exploitation techniques. The Xero-thermal power system is appropriate for regions with shallow heat sources and mild temperature gradients since it generates energy from low-temperature geothermal resources. Flash geothermal power systems are appropriate for locations with hot fluids. Binary cycle generation system employs a secondary working fluid with a boiling point that is lower than water, allowing for power generation from lower temperature geothermal resources, thereby expanding the potential for geothermal energy production. The study then largely focuses on the key elements, such as resource availability, technological hurdles, and market conditions, that can influence the utilization of geothermal energy. Researchers and engineers can more clearly comprehend the benefits and constraints in various resource environments by closely evaluating these elements. While the government should urge the people to pay greater attention to the exploitation and deployment of renewable energy, engineers could improve drilling techniques. The current situation of harnessing and exploiting geothermal energy highlights the necessity for ongoing research and development to fully realize geothermal energy's potential. This essay contributes to the larger conversation on renewable energy and offers insightful information about the significance of geothermal energy.
Response of the Biological Components to Climate Change in the Wetland Ecosystem of the Qinghai-Tibet Plateau
Authors: Li Jiaxuan
Published: December 2023

Alpine wetlands play a role in water conservation, climate regulation, carbon sequestration, and biodiversity protection. However, due to the unique geological structure and climate characteristics of alpine areas, climate change is highly likely to have an impact on alpine wetlands and their ecosystems, including the abundance and distribution of local species. This paper focuses on analyzing the composition, quantity, and distribution changes of wetland organisms, including producers, consumers, and decomposers. The research findings indicate that, with the intensification of human activities and climate change such as global warming, despite the emergence of some new wetlands, many natural alpine wetlands on Qinghai-Tibet Plateau are facing shrinkage and are gradually retreating towards higher altitudes, latitudes, and wetter areas, which means the extinction of some plants and the shrinkage of wildlife habitats. Changes in wetland environment, such as drying, resulting from increased temperature and decreased precipitation, have led to a decline in biodiversity and degradation of alpine wetland ecosystems. Despite an overall increase in vegetation cover, wetland degradation has caused changes in plant species diversity and community composition. Climate warming have also affected wildlife migration and the activity of microorganisms. The changes in plateau wetlands are primarily shaped by climate conditions, while human activities act as accelerators, causing significant damage to wetland environments, leading to fragmentation and accelerated degradation. This paper proposes strengthening ecological monitoring and risk assessment in these regions, conducting further research, and promptly implementing necessary restoration measures to reduce the ecological risks caused by these changes.
Environmental Concerns in Marine Ecology and Strategies for Sustainable Development
Authors: Jia Chuheng
Published: December 2023

Since the commencement of the Industrial Revolution, there has been a gradual and consistent escalation in the level of carbon dioxide emissions, thus causing a drastic alteration in the global climate. As the most substantial ecological environment system on Earth, the marine ecological environment system has also undergone substantial impacts as a result of these climatic changes. Despite its vast size, minor environmental dilemmas were not emphasized initially, leading to momentous qualitative changes caused by the quantitative ones; consequently, human face critical concerns related to marine ecological environment today. The intent of this study is to delineate corresponding sustainable development approaches for the persisting environmental issues under the theoretical framework of sustainable development. Initially, the causes of climate change are discussed, and the undeniably significant role humans have played is examined. Subsequently, alterations in climate change affect various segments of the marine ecosystem differently concerning seawater hydrological conditions, consequently producing a series of chain reactions that ultimately affect the overall marine ecological environment. Various sustainable development strategies have been proposed under the theoretical framework of sustainable development to address the multiple minor problems that contribute to the overall marine ecological environment issues. This study endeavors to present an extensive summary of the marine ecological environment issue in its entirety; however, it should be followed by further in-depth analysis and consolidation of the ecological environment issues of disparate links in the ecosystem, thereby increasing the effectiveness of the targeting approach. This paper expects that through this study, the specific impact of climate change on the marine ecological environment and the direction that human society must work towards to achieve improvement would be made more evident.

Achieving net-zero carbon emissions is a fundamental way to slow global warming, and dealing with massive carbon emissions from the construction industry is a priority. These days, with the growth of the clean energy industry, the market for photovoltaic (PV) power generation using solar energy is booming. In order to estimate PV power potential on a large scale, geographic information systems (GIS) have been applied in case studies in selected areas; however, there is a lack of overview of the comprehensive application of GIS technology in this subject. In this paper, the application of GIS in estimating PV potential is thoroughly analyzed from three perspectives: data source, application, and limitation. In terms of data source, this paper classifies the data into low, medium, and high precision, and the merits and demerits of each class are analyzed. The paper divides the application into two parts: calculating the received solar energy and the available roof area. The former analyses two available plug-ins in GIS software and a calculation formula that combines with GIS. The latter includes a variety of methods for calculating the total roof area, shading effects, vegetation coverage, and tilt & Azimuth. Although using GIS to estimate PV potential is well-developed, there are still limitations regarding accuracy, speed, and data accessibility. This paper hopes to contribute to the estimation of PV power potential to reach a higher level of accuracy and maturity in order to promote more projects and constructions with large-scale PV power generation systems. Indeed, the future of PV power generation is promising and will be a significant step towards net-zero carbon dioxide emissions for all humankind.

Faced with the increasing loss of resources and the worsening of environmental pollution, the country is also paying more and more attention to the recycling of resources and pollution control. At present, biomass as a new energy can improve the utilization of resources and environmental conditions. This paper focuses on the basic content of biochar, the status of soil heavy metal pollution and the effect of biochar on the control of heavy metal pollution. Studies have shown that biochar can convert part of exchangeable heavy metals in soil into a stable state through passivation, and the other part of heavy metals can be absorbed by plants to achieve the purpose of repairing soil plants, thereby indirectly improving soil characteristics. In addition, biochar can also use chemical leaching method to remove heavy metal pollutants in soil by leaching solution to improve soil heavy metal pollution. In order to better optimize the use of resources and improve environmental pollution, we should explore the interaction between biomass energy and environmental media more deeply, and innovate the technologies and methods of birth matter energy in pollution control. The combination of biomass and heavy metal pollution control can not only promote more in-depth research on biomass properties, but also make great contributions to human resource recovery and environmental pollution control.
