A data-driven battery health status evaluation method based on electrochemical models, big data, and mathematical statistics is proposed in this paper to address the issues of long cycle, low efficiency, and high cost in current battery health status detection. This detection method in this study first calculates the Soc-power parameters of the vehicle series based on the log data of valid orders in the history of the vehicle series. Then, combined with the data of each order, the initial evaluation capacity of the order is calculated. Next, an anomaly detection algorithm is used to exclude abnormal orders from the vehicle within the past 60 days. The average of the initial evaluation capacity of the order is used to obtain the final evaluation capacity of the order. Finally, a sliding average is used to obtain the evaluation capacity of the battery, divide the evaluated capacity by the nominal capacity to obtain the battery health status. Based on this technology, the current health status of the battery can be quickly and accurately obtained, while reducing the detection cost and cycle, allowing for real-time detection of the battery's health status.

Global warming is currently one of the foremost environmental challenges, exerting a profound and extensive influence on natural ecosystems. The alteration of forest litter, as a crucial source of organic matter within these ecosystems, plays a pivotal role in the context of global warming. Litter decomposition represents the process through which carbon and nutrients contained therein are transferred, serving as a crucial nexus for vegetation-litter-soil nutrient cycling and biogeochemistry, playing a significant role in soil nutrient composition. This paper aims to investigate the impact of global warming-induced changes in certain factors on the rate of forest litter decomposition, while evaluating their potential implications for ecosystem function, the carbon cycle and climate change. This study delves into the complex interplay between various environmental factors and their impact on forest litter decomposition. The five factors examined in this research—temperature, precipitation, snow cover and associated freeze-thaw phenomena, soil composition, and disasters—all play a crucial role in shaping the rate of decomposition. Based on the findings presented in this paper, it can be inferred that global warming will exert direct or indirect influences on forest litter decomposition from multiple perspectives.

With the global energy demand on the rise, lithium-ion batteries (LIBs) have attracted more attention as they play a pivotal role in electrification revolution.

Pacific Decadal Variability (PDV) plays a pivotal role in understanding climate shifts. This study focuses on investigating the primary components of PDV, namely, the Pacific Decadal Oscillation (PDO) and the North Pacific Gyre Oscillation (NPGO). These components are defined as the first and second principal modes of the North Pacific sea surface temperature anomaly field. Our analysis indicates that under the influence of global warming, both PDO and NPGO exhibit a weakening of the amplitude and a shortening of the period. Furthermore, NPGO demonstrates a more pronounced response to a 2°C warming scenario compared to a 1.5°C increase. This heightened sensitivity is attributed to the accelerated propagation of Rossby waves, a consequence of enhanced ocean stratification. The findings of this research contribute to the establishment of a scientific foundation for informed environmental policy development, facilitating the promotion of environmental conservation and sustainable development.

Beta-blockers, also known as β-blockers, are a class of medications commonly prescribed to treat arrhythmias (Drugs such as Bisoprolol, metoprolol succinate), prevent secondary heart attacks, and sometimes manage hypertension. These drugs inhibit the activity of endogenous catecholamines—namely epinephrine and norepinephrine—within the sympathetic nervous system by targeting adrenergic beta-receptors. While some beta-blockers non-competitively block all beta-adrenergic receptors, others do so in a competitive manner. It is targeted at the beta receptor on the cell wall, selectively binds to the beta adrenergic receptor, antagonizes the excitatory effect of neurotransmitters and catecholamines on the beta receptor, and is mainly used in the treatment of hypertension, coronary heart disease, heart failure and other diseases, which can cause adverse reactions. Moreover, It may cause bradycardia, second degree type II and above atrioventricular block, bronchial asthma, and hypotension. Central nervous system adverse reactions, multiple dreams, hallucinations, insomnia, fatigue, vertigo and depression and other symptoms, especially high-fat soluble β-blockers, easy to cross the blood-brain barrier to cause adverse reactions, such as propranolol. The commonly used β-blockers in clinic include metoprolol, atenolol and ecolol. In the United States Food and Drug Administration (FDA) classification of drugs according to the degree of harm to pregnant women, most drugs are classified as class C or D.

Stainless steel, an alloy of iron and chromium with the inclusion of other elements, has gained significant prominence in the construction industry due to its remarkable properties such as corrosion resistance, high strength, good durability, and aesthetic quality.

Due to these properties, stainless steel is widely used in the architecture of different countries. However, there are still some challenges for it to overcome, including the high production costs, poor thermal conductivity, and large weight. Moreover, it is easy to rust after a long time exposure to chemicals such as chloride and sulfide. Therefore, it is necessary to further optimize stainless steel from various aspects.

Light pollution refers to the inappropriate and excessive use of artificial light. The increasing extent and intensity of artificial light has impacted the biology and ecology of species significantly. Admittedly, the widespread use of light benefits people to a large extent and is positively associated with modernization, security, and wealth. But its catastrophic effects can never be ignored. To be specific, light pollution can arouse negative health impacts such as headaches, dizziness, increased anxiety, pressure, and fatigue. The paper wants to find applicable indicators regarding the risk levels of light pollution and establish criteria to judge the risk of light pollution in different areas. In the process, the research first measures the interconnection between the indicators, which are chosen to reflect the risk of light pollution, and then uses PCA to implement dimensionality reduction so as to simplify the model. After that, EWM and TOPSIS are applied to determine the weight of each indicator and the rating of the cities. Institutions or governments that are responsible for managing light pollution can then use the model to judge the risk level of different cities. The model can help to avoid overlooking or overemphasizing a city's light pollution risk level, providing a more accurate estimation. In this case, institutions and the government can take better and more effective measures to restrict light pollution.

Under the social background of energy shortage, climate change and environmental pollution, people’s demand for renewable energy is increasing. Solar energy is an important choice, but the problem of “cost efficiency and low” of traditional silicon solar cells has not been effectively solved. Perovskite solar cells (PSCs) were discovered in 2012 by researchers who overcame the conventional issues. The PSCs are made up of three layers of electrodes: a perovskite layer, an electron transport layer, and a hole transport layer. In-depth descriptions of the n-i-p and p-i-n structures are also provided. PSCs also have difficulties with environmental safety, dependability, and stability. Interface engineering is an important strategy, which can improve the performance and life of the battery by optimizing the energy level matching between various layers, defect passivation and carrier transport. With the progress of science and technology and the optimization of equipment, the problem of non-uniformity of perovskite layer on rigid non-planar surface can be significantly improved by using ultrasonic spraying technology. Through the optimization of the production process and composition configuration of PSCs, some related discussions are carried out, hoping to improve and help the scientific research project and some energy industries.
