Vehicle speed measurement method using monocular cameras.
Sci Rep
January 2025
Computer and Information Engineering College, Inner Mongolia Agricultural University, Hohhot, 010000, China.
This paper proposes a method for fast and accurate vehicle speed measurement based on a monocular camera. Firstly, by establishing a new camera imaging model, the calibration method for variable focal lengths is optimized, simplifying the transformation process between the four coordinate systems in traditional camera imaging models, and the method does not need to restore the pixel coordinates to dedistortion. Secondly, based on the camera imaging model, a two-dimensional positioning algorithm is proposed.

Background: Although the information on the validation status of electronic sphygmomanometer (ES) devices in use in health care institutions and households is much more clinically relevant than that of ES models available on the market, it remains insufficient.
Methods: A national survey was conducted across all administrative regions of mainland China to assess the validation status of ESs. Fifty-eight cities were selected with stratification by municipality, provincial capital, and other cities, and health care institutions and households in each city were chosen by convenience to identify ES devices in use according to the study protocol.
Responses of fungal communities at different soil depths to grazing intensity in a desert steppe.

Institute of Grassland Research, Chinese Academy of Agricultural Sciences, Hohhot, Inner Mongolia, China.
Grazing can alter the physicochemical properties of soil and quickly influence the composition of microbial communities. However, the effects of grazing intensity on fungal community composition in different soil depth remain unclear. On the Inner Mongolia Plateau, we studied the effects of grazing intensity treatments including no grazing (NG), light grazing (LG), moderate grazing (MG), heavy grazing (HG), and over grazing (OG) on the physicochemical properties and fungal community composition of surface (0-20 cm) and subsurface (20-40 cm) soil layers.

As an important strategic energy base in China, Inner Mongolia's energy exports are dominated by coal and electricity. Under the background of "double carbon" target, the energy transition of Inner Mongolia is of great significance to China's energy security and carbon emission reduction. Based on the energy policy simulation model (EPS model), this paper explores the path of energy transition in Inner Mongolia by constructing the scenarios of developing renewable energy, developing CCS technology and carbon pricing, and simulating the policy situation based on the reality of Inner Mongolia and the energy transition experience of developed countries and regions.

Article Synopsis
- The study investigates the presence of multidrug-resistant Escherichia coli in calves with diarrhea in Tongliao, China, highlighting the problematic use of antibiotics that contributes to drug resistance.
- Researchers identified 40 isolated strains, all showing resistance to several antibiotics, with high levels of specific antibiotic resistance genes detected in each strain, particularly in three strains (11, 23, and 24) that exhibited severe resistance.
- Whole-genome sequencing revealed a significant number of antibiotic resistance genes within the isolated strains, indicating a serious threat of gene transfer and amplifying concerns about the rising issue of antibiotic resistance in the region.
