One-Leg Standing Test with Eyes Open as a Screening Tool for Prefrailty in Community-Dwelling Older Japanese Women.

: One-leg standing test with eyes open (OLST), a well-known balance assessment, is simple to implement and requires no special measuring equipment or space. Prefrailty has greater reversibility than frailty, and early detection of prefrailty is essential for frailty prevention in older adults, especially women. However, the association between the OLST and prefrailty remains unclear.

Land use assessment under dynamic evolution: Multi-objective optimization and multi-scenario simulation analysis.

The efficient use of land resources is key to achieving the dual goals of "carbon neutrality" and high-quality development while addressing the challenges of imbalance between ecological protection and economic development in river basins. This study combines remote sensing data with land use change modeling to generate maps of land use changes in the past and present, and by integrating the Grey multi-objective optimization-Patch-level land use simulation (GMOP-PLUS) model with the Coupled Model Intercomparison Project 6 (CMIP 6) development pathways, it has defined 12 target scenarios to simulate and predict the trends of changes over the next 30 years, providing a basis for formulating future land management policies. We found that from 1980 to 2020, grassland dominated (41%), with the largest increase in built-up land, and a decrease in unused land and cropland by 5.

In-MIL-68 derived InO/FeO shuttle-like structures with n-n heterojunctions to improve ethanol sensing performance.

Metal-organic frameworks (MOFs) have a variety of structures and unique properties that make them suitable for use in gas sensors. Herein, InO/FeO was successfully synthesized using simple solvothermal and impregnation methods. The response to 100 ppm of ethanol gas reached 67.

Dynamic analysis of soil erosion in the affected area of the lower Yellow River based on RUSLE model.

With the accelerated development of urbanization, the exploration and usage of land resources is becoming more and more frequent, which leads to the decline of soil quality, resulting in a series of soil ecological issues, such as soil nutrient loss, soil quality degradation and destruction. At present, the contradiction between soil erosion and sustainable development of human society has become one of the hot issues studied by scholars. The Yellow River Basin is an important experimental area for high-quality development in China, constructing the Yellow River Ecological Economic Belt play an important role in China's regional coordinated development.

Hydrothermal synthesis of a bimetallic metal-organic framework (MOF)-derived CoO/SnO composite as an effective material for ethanol detection.

This study utilized a hydrothermal method and air calcination to prepare a bimetallic metal-organic framework (MOF) derived CoO/SnO nanocomposite material, which was employed as a sensing material for ethanol detection. The structure, elemental composition, and surface morphology of CoO/SnO nanocomposite materials were defined using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Compared to SnO nanoparticles derived from metal-organic frameworks, the bimetallic metal-organic framework-derived CoO/SnO nanocomposite material exhibits significantly superior ethanol sensing performance.

Spatial heterogeneity and scenario simulation of carbon budget on provincial scale in China.

Background: Conducting an extensive study on the spatial heterogeneity of the overall carbon budget and its influencing factors and the decoupling status of carbon emissions from economic development, by undertaking simulation projections under different carbon emission scenarios is crucial for China to achieve its targets to peak carbon emissions by 2030 and to achieve carbon neutrality by 2060. There are large disparities in carbon emissions from energy consumption, the extent of land used for carbon absorption, and the status of decoupling of emissions from economic development, among various regions of China.

Results: Based on night light data and land use data, we investigated carbon budget through model estimation, decoupling analysis, and scenario simulation.

Does Forest Soil Fungal Community Respond to Short-Term Simulated Nitrogen Deposition in Different Forests in Eastern China?

Nitrogen (N) deposition has changed plants and soil microbes remarkably, which deeply alters the structures and functions of terrestrial ecosystems. However, how forest fungal diversity, community compositions, and their potential functions respond to N deposition is still lacking in exploration at a large scale. In this study, we conducted a short-term (4-5 years) experiment of artificial N addition to simulated N deposition in five typical forest ecosystems across eastern China, which includes tropical montane rainforest, subtropical evergreen broadleaved forest, temperate deciduous broadleaved forest, temperate broadleaved and conifer mixed forest, and boreal forest along a latitudinal gradient from tropical to cold temperature zones.

Understanding Relationships between Cultivated Land Pressure and Economic Development Level across Spatiotemporal Characteristics: Implications for Supporting Land-Use Management Decisions.

Food security is crucial to world peace. Economic development has posed a great threat to the protection of cultivated land. Considering 20 cities in the lower Yellow River (AALYR) as the study area, this study explored the spatial evolution of cultivated land pressure (CLP) and economic development from 1998 to 2018, revealing the spatiotemporal coupling characteristics of the CLP index and economic development.

Spatiotemporal characteristics of soil erosion in a typical watershed consisting of different landscape: A case study of the Qin River Basin.

Soil erosion has a severe impact on habitat and productivity. It is considered to be a major environmental threat prevalent in ecosystems. However, few researchers have studied the spatial distribution of soil erosion intensity among different geographic environmental factors.

A Low-Power CMOS Wireless Acoustic Sensing Platform for Remote Surveillance Applications.

A low-power wireless acoustic sensing platform for remote surveillance applications based on a 180 nm CMOS technology is proposed in this paper. The audio signal, which is acquired by a microphone, is first amplified and filtered. Then, the analog signal is converted to a digital signal by a 10-bit analog-to-digital converter (ADC).
