Molecular Physiological Evidence for the Role of Na-Cl Co-Transporter in Branchial Na Uptake in Freshwater Teleosts.

The gills are the major organ for Na uptake in teleosts. It was proposed that freshwater (FW) teleosts adopt Na/H exchanger 3 (Nhe3) as the primary transporter for Na uptake and Na-Cl co-transporter (Ncc) as the backup transporter. However, convincing molecular physiological evidence to support the role of Ncc in branchial Na uptake is still lacking due to the limitations of functional assays in the gills.

[Responses of plant community diversity to human disturbance in temperate grassland with different soil parent materials].

Based on community investigation data from grasslands on two different soil parent material types (loess and sand parent materials) and under three human utilization modes in the Saihan Ullah Reserve, we calculated human disturbance index (HDI) and biodiversity indices and analyzed the interactions between species diversity and degradation levels. The results showed that degradation status varied across different soil parent material types and human utilization modes, and that degradation levels of loess and sand parent materials both increased with the enhancement of human utilization intensification. HDI of loess parent material grasslands (mean value of 1.

A Differentiable Dynamic Model for Musculoskeletal Simulation and Exoskeleton Control.

An exoskeleton, a wearable device, was designed based on the user's physical and cognitive interactions. The control of the exoskeleton uses biomedical signals reflecting the user intention as input, and its algorithm is calculated as an output to make the movement smooth. However, the process of transforming the input of biomedical signals, such as electromyography (EMG), into the output of adjusting the torque and angle of the exoskeleton is limited by a finite time lag and precision of trajectory prediction, which result in a mismatch between the subject and exoskeleton.
