Application of conjugated polymer nanocomposite materials as biosensors in rehabilitation of ankle joint injuries in martial arts sports.

In order to understand the application of conjugated polymer nanocomposites as biosensors in the rehabilitation of ankle joint injuries in martial arts, the author proposes a study on the application of conjugated polymer nanocomposites in the rehabilitation of ankle joint injuries in martial arts. Firstly, in martial arts training, the incidence of ankle joint injuries is relatively high. In order to prevent and reduce ankle joint injuries, high-intensity martial arts training should be used to evaluate the degree of ankle joint injuries in a timely manner using an ankle joint injury assessment model.

Accumulation of production capital and income growth of Chinese farmers in the post-poverty alleviation era: A study based on a two-way fixed effects model with CFPS data.

Agricultural mechanization is a crucial indicator of modernization in agriculture. It improves productivity and underpins the evolution of a modern state. This study scrutinizes the enduring effects of government subsidies on farm machinery acquisition, income growth, and capital accumulation in rural households.

A Multi-Scale-Enhanced YOLO-V5 Model for Detecting Small Objects in Remote Sensing Image Information.

As a typical component of remote sensing signals, remote sensing image (RSI) information plays a strong role in showing macro, dynamic and accurate information on the earth's surface and environment, which is critical to many application fields. One of the core technologies is the object detection (OD) of RSI signals (RSISs). The majority of existing OD algorithms only consider medium and large objects, regardless of small-object detection, resulting in an unsatisfactory performance in detection precision and the miss rate of small objects.

Recent advances and understanding of high-entropy materials for lithium-ion batteries.

Lithium-ion batteries (LIBs) has extensively utilized in electric vehicles and portable electronics due to their high energy density and prolonged lifespan. However, the current commercial LIBs are plagued by relatively low energy density. High-entropy materials with multiple components have emerged as an efficient strategic approach for developing novel materials that effectively improve the overall performance of LIBs.

Dynamic Deformation Reconstruction of Variable Section WING with Fiber Bragg Grating Sensors.

In order to monitor the variable-section wing deformation in real-time, this paper proposes a dynamic reconstruction algorithm based on the inverse finite element method and fuzzy network to sense the deformation of the variable-section beam structure. Firstly, based on Timoshenko beam theory and inverse finite element framework, a deformation reconstruction model of variable-section beam element was established. Then, considering the installation error of the fiber Bragg grating (FBG) sensor and the dynamic un-modeled error caused by the difference between the static model and dynamic model, the real-time measured strain was corrected using a solidified fuzzy network.

Qualitative Identification of the Static Pull-In and Fundamental Frequency of One-Electrode MEMS Resonators.

This paper attempts to qualitatively identify the static pull-in position, pull-in voltage, and fundamental frequency of one-electrode microresonators from a physical perspective. During theoretical derivation, a generalized one-degree-of-freedom (1-DOF) model in nondimensional form derived using the differential quadrature method (DQM) is first introduced and then transformed for frequency normalization. Based on the deduced formulas, the upper and lower bounds of the static pull-in position and pull-in voltage are both deduced through mathematical proof.

Vibration Identification of Folded-MEMS Comb Drive Resonators.

Natural frequency and frequency response are two important indicators for the performances of resonant microelectromechanical systems (MEMS) devices. This paper analytically and numerically investigates the vibration identification of the primary resonance of one type of folded-MEMS comb drive resonator. The governing equation of motion, considering structure and electrostatic nonlinearities, is firstly introduced.

Aerobic Exercise Suppresses Atherosclerosis Through Adiponectin-Nuclear Transcription Factor κB Pathway in Apolipoprotein E-deficient Mice.

Background: We aimed to investigate the therapeutic effect of aerobic exercise on atherosclerosis (AS) in apolipoprotein E-deficient mice and the adiponectin (ApN)-nuclear transcription factor κB (NF-κB) pathway involved in the related anti-inflammation.

Materials And Methods: ApoE-deficient mice with AS (AS+C), and ApoE-deficient mice with AS and aerobic exercise (AS+E) were investigated for body weight and visceral fat. Pathomorphology of the aortic vascular wall was qualitatively and quantitatively evaluated with hematoxylin-eosin staining.
