    Abstract Several recent studies have used virtual reality (VR)-based exercise to enhance functional fitness in older adults. However, most of these studies exclusively focused on short-term intervention outcomes. Therefore, this study aimed to determine the effect of VR-based exercise on older adults’ retention of functional fitness after intervention and at follow-up.This study was a randomized controlled trial wherein older adults (mean age: 72.16 ± 4.9 years) were assigned to experimental ( n = 48) and control ( n = 50) groups. Experimental group participants engaged in VR exercise sessions for 75 to 90 minutes biweekly over 12 weeks. Control group participants did not participate in the intervention. Functional fitness was assessed using the Senior Fitness Test. Functional fitness changes were compared using a generalized estimating equation. Pre-, post-, and follow-up tests were conducted at weeks 1, 13, and 24, respectively. After VR-based training, the experimental group performed better in functional fitness tests, including upper body flexibility, lower body flexibility, upper body strength, cardiorespiratory fitness, balance, and agility, than the control group immediately after the intervention. Improvements in lower body flexibility, upper body strength, cardiorespiratory fitness, balance, and agility persisted in the experimental group for up to 12 weeks. This study demonstrates that VR-based training potentially improves community-dwelling older adults’ functional fitness. Its findings may support the future development of novel exercise technologies and serve as a reference for the implementation of physical health promotion strategies for older adults.

    Abstract This paper examines the contested agendas generated by Tai Lake Basin’s (TLB) recent wetland constructions and how these dynamics have stimulated the particular aspirations concerning nature among various local actors. Through interviews with local ecologists, landscape architects, and environmental engineers, this paper details how they convergently subscribe to the ethical claims of humans and nature during the decision making in constructing wetlands. I termed these dynamic considerations as ‘Ecological Governmentality.’ Under the influence of environmental conservation as a global consensus, the idea of ‘wetland’ has regained prevalence among Chinese cities’ plans and policies in recent decades. In the TLB, one of the most developed regions in China’s southeast coastal areas, over 800 ‘wetland parks’ have been established. Situated in the basin context, this paper further problematizes three modalities of wetland construction in the case of Suzhou city, namely: National Certificated Wetland Parks propelled by international environmental conservation agendas, Urban Wetland Landscape Parks associated with urban redevelopment, and Engineering Constructed Wetlands generated by the opening niche market for municipal waterworks. The construction of these parks has made prominent attempts to rewild urban environment through re-territorialization, design, and technology innovations intersected with moral claims that go beyond pure scientific concerns of ecology. Building on the concept of ‘worlding practices’ and ‘governmentality,’ three cases in this paper illustrate how the mainstreaming of wetlands in Suzhou has been materialized along with the shared notion of city branding from global neoliberal urbanization. More specifically, this paper explores the diverse materialization through the lens of contested ethical aspirations and transferred roles taken by different actors in the local wetland governance. The emerging ‘Ecological Governmentality’ in wetland construction helps to consolidate the unique ecological ...

    Abstract The 2019 coronavirus disease pandemic has been a governance challenge for countries and cities worldwide. In China, the community-based joint prevention and control governance mechanism is one of the highlights of the “Chinese experience” in fighting the pandemic. As aging accelerates, communities can take on more functions in managing the health of their residents. Especially in the post-pandemic era, the actual needs of community residents in terms of health, medical care, and elderly care need to be addressed. This paper uses a questionnaire to understand the current situation of community health management in Beijing, followed by the selection of four typical communities for in-depth interviews, and uses the triple process of open coding, selective coding, and theoretical coding of the grounded theory to analyze residents' needs and willingness for proactive health management. More than 80 concepts, 41 categories, and 6 master categories were obtained from 204 initial statements. The “logical line” of the relationship between the main categories was constructed, and we developed a conceptual model of community-based proactive health management, consisting of six dimensions: (1) perception and willingness, (2) primary population, (3) health behavior paradigm, (4) management mechanism, (5) information technology applications, and (6) facilities and services. The study aims to contribute to the community-based health management in China and for the international community and provide strategies to improve community-based health management.

    Abstract The benign interaction between technological innovation, industrial structure, and ecological environment optimization is important for the sustainable development of China’s economy. Based on panel data from 30 provinces (municipalities) in China from 2003 to 2019, a coupling coordination degree (CCD) model was adopted to evaluate the coordinated development level of the technological innovation-industrial structure-ecological environment system (TIE). Fixed-effect models were used to explore the subsystem impact on the coupling coordination level. A fully modified least-squares (FMOLS) method was used to analyze TIE subsystem interactions. The results show the following: (1) The coordinated development level of TIE has steadily improved. The CCD of the TIE was high in the east, flat in the center, and low in the west. (2) Subsystem development significantly and positively affected the degree of coupling coordination. The ecological environmental impact on the coordinated development level was the largest in the eastern regions and the influence of technological innovation on the coordinated development level was the largest in the central and western regions. (3) Industrial advancement had a positive impact on technological innovation in 30 provinces as a whole, and in the eastern, central, and western regions. A “U”-shaped relationship was found between technological innovation and industrial advancement in all 30 provinces, and in the eastern, central provinces. Industrial rationalization, industrial advancement, and technological innovation can promote the improvement of the ecological environment in all 30 provinces, and the eastern, central, and western regions.

    Abstract Due to the limitations of traditional retinal blood vessel segmentation algorithms in feature extraction, vessel breakage often occurs at the end. To address this issue, a retinal vessel segmentation algorithm based on a modified U-shaped network is proposed in this paper. This algorithm can extract multi-scale vascular features and perform segmentation in an end-to-end manner. First, in order to improve the low contrast of the original image, pre-processing methods are employed. Second, a multi-scale residual convolution module is employed to extract image features of different granularities, while residual learning improves feature utilization efficiency and reduces information loss. In addition, a selective kernel unit is incorporated into the skip connections to obtain multi-scale features with varying receptive field sizes achieved through soft attention. Subsequently, to further extract vascular features and improve processing speed, a residual attention module is constructed at the decoder stage. Finally, a weighted joint loss function is implemented to address the imbalance between positive and negative samples. The experimental results on the DRIVE, STARE, and CHASE_DB1 datasets demonstrate that MU-Net exhibits better sensitivity and a higher Matthew’s correlation coefficient (0.8197, 0.8051; STARE: 0.8264, 0.7987; CHASE_DB1: 0.8313, 0.7960) compared to several state-of-the-art methods.

    Abstract Catalyzed by COVID-19 and the Russia–Ukraine conflict, oil prices fluctuate dramatically on the worldwide market. Both international oil price changes and carbon tax policies have a direct impact on energy costs, thus influencing energy security and emission reduction impacts. Therefore, assessing the interaction effects of international oil price variations and carbon tax policies can assist in resolving the competing challenges of energy security and carbon emission reduction. The impact of international oil price fluctuations on China’s energy–economic–environment system under the baseline scenario and carbon taxation scenario is analyzed by constructing a computable general equilibrium model comprising six modules: production, trade, institutions, price, environment, and equilibrium. The findings indicate that, in addition to reducing high-carbon energy consumption and increasing demand for clean electricity, rising international oil prices have a negative effect on real GDP, resulting in lower output in sectors other than construction, and a positive effect on the environmental system by driving carbon emission reductions. In contrast, decreasing international oil prices have the opposite effect. Nevertheless, the impact of rising and decreasing international oil prices is asymmetrical, with the positive shock effect being smaller than the negative. The carbon tax policy can effectively offset the increase in carbon emissions caused by the decline in international oil prices, which is conducive to promoting the development of clean energy, while simultaneously causing an increase in product prices and arousing a contraction in consumer demand, which has a limited negative impact on the macroeconomy.

    Abstract Recent theoretical studies have identified chaotic dynamics in eco-evolutionary models. Yet, empirical evidence for eco-evolutionary chaos in natural ecosystems is lacking. In this study, we combine analyses of empirical data and an eco-evolutionary model to uncover chaotic dynamics of body length in a fish population (northeast Arctic cod: Gadus morhua). Consistent with chaotic attractors, the largest Lyapunov exponent (LE) of empirical data is positive, and approximately matches the LE of the model calculation, thus suggesting the potential for chaotic dynamics in this fish population. We also find that the autocorrelation function (ACF) of both empirical data and eco-evolutionary model shows a similar lag of approximately 7 years. Our combined analyses of natural time series and mathematical models suggest that chaotic dynamics of a phenotypic trait may be driven by trait evolution. This finding supports a growing theory that eco-evolutionary feedbacks can produce chaotic dynamics.

    Abstract In this study, a simple and environmentally friendly method was developed for the extraction of seven active coumarins from Angelica dahurica (Hoffm.) Benth. & Hook.f. ex Franch. & Sav. (A . dahurica ) based on deep eutectic solvents (DESs). Among the 16 kinds of DES based on choline chloride, the DES system with the molar ratio of choline chloride, citric acid, and water as 1:1:2 had the best extraction effect. Ultrasonic-assisted response surface methodology (RSM) was used to investigate the optimal extraction scheme. The results showed that the optimal extraction conditions were a liquid–solid ratio of 10:1 (mL/g), an extraction time of 50 min, an extraction temperature of 59.85 °C, and a moisture content of 49.28%. Under these conditions, the extraction yield reached 1.18%. In addition, scanning electron microscopy (SEM) was used to observe the degree of powder fragmentation before and after extraction with different solvents. The cells of A. dahurica medicinal materials obtained by DES ultrasonic-assisted treatment were the most seriously broken, indicating that DES had the highest efficiency in the treatment of A. dahurica . The 1,1-diphenyl-2-picrylhydrazyl (DPPH) DPPH radical scavenging model was used to evaluate the biological activity of DES extract. The results showed that DES extract had better scavenging ability of DPPH free radical. Therefore, DES is a green solvent suitable for extracting coumarin compounds of A . dahurica , with great potential to replace organic solvents.

    Abstract Cyanuric acid is a widely used fine chemical intermediate that acts as a free chlorine buffer in swimming pool water, wherein it is often used as a stabilizer to maintain the germicidal efficacy of chlorinated disinfectants. However, it has also been associated with health risks. Herein, we introduced the sources and functions of cyanuric acid in swimming pool water, focusing on potential health risks associated with excessive concentration of the component and the current control standards worldwide. Also, the prevention and control measures were summarized in terms of physical chemistry, biodegradation, and ultraviolet radiation to provide a basis for the development of public health policies for swimming pool management.

    Abstract Summary: Pollen germination is an essential step for delivering sperm cells to the embryo sac for double fertilization in flowering plants. The cytosolic Ca2+ concentration ([Ca2+]cyt) and vesicle dynamics are critical for pollen germination, but their potential correlation in pollen grains is not fully understood. Here, we report that [Ca2+]cyt oscillates periodically at the prospective germination sites during pollen germination. The [Ca2+]cyt is mainly from extracellular Ca2+ ([Ca2+]ext) influx, which implicates the Ca2+-permeable ion channel cyclic nucleotide-gated channel 18 (CNGC18). The [Ca2+]cyt oscillations spatiotemporally correlate with the accumulation of secretory vesicles labeled by a formin protein AtFH5, and disruption of vesicle accumulation inhibits the [Ca2+]cyt oscillations. In turn, the [Ca2+]cyt oscillations promote exocytosis, which leads to stepwise cell extension during pollen germination. Together, these data provide a timeline of vesicle dynamics, calcium oscillation, and exocytosis during pollen germination and highlight the importance of the correlation of these events for pollen germination.
