[Progress in leaf area index retrieval based on hyperspectral remote sensing and retrieval models].

The leaf area index (LAI) is a very important parameter affecting land-atmosphere exchanges in land-surface processes; LAI is one of the basic feature parameters of canopy structure, and one of the most important biophysical parameters for modeling ecosystem processes such as carbon and water fluxes. Remote sensing provides the only feasible option for mapping LAI continuously over landscapes, but existing methodologies have significant limitations. To detect LAI accurately and quickly is one of tasks in the ecological and agricultural crop yield estimation study, etc.

Twelve cases of the pectoralis major muscle tendon rupture with surgical treatment-an average of 6.7-year follow-up.

Background: Pectoralis major tendon rupture is a relatively rare injury leading to both functional and cosmetic deficiency. The peak torque of the pectoralis major is significantly decreased after conservational treatment of a total rupture. We suppose that surgical intervention is better choice.

Medial plica after reconstruction of anterior cruciate ligament.

Background: The medial plica may be caused by direct trauma or joint degeneration, which also could be iatrogenic. There have been few reports in the literature discussing incidence of the medial plica caused by an operation on the knee joint, specifically after the reconstruction of anterior cruciate ligament (ACL). In this study, we aimed to evaluate and analyze the relationship between the incidence of the medial plica and reconstruction of the ACL.

Effects of Ce on the short-term biocompatibility of Ti-Fe-Mo-Mn-Nb-Zr alloy for dental materials.

Effects of Ce on the short-term biocompatibility of Ti-Fe-Mo-Mn-Nb-Zr alloy designed for implant materials were studied by acute toxicity test, hemolytic test, and MTT assay. The elements and their concentration in surface films and extraction media of Ti alloys were investigated with XPS and ICP, respectively. The primary compositions of the surface films of Ti alloys with 0.
