Measuring upper limb movement to analyze intra-body communication channel attenuation characteristics.

Background: This experiment was designed to study the respective effects of the closed-state human palm and dynamic arm bending on intra-body communication channel attenuation.

Methods: We selected the right upper arm of a healthy adult male as the experimental object to measure channel attenuation variation in a closed or open palm, and when the arm was bent, so as to analyze channel characteristics.

Conclusions: The experiment showed that, in a quasi-static stable system, the effects of a closed palm on channel attenuation were negligibly minimal.

Proteomic investigation of resistance to chemotherapy drugs in osteosarcoma.

Background: Osteosarcoma, which is also termed osteogenic sarcoma or osteoma sarcomatosum, is the most common form of bone cancer. Typical osteosarcoma can occur at any age, including in infants, children, and the elderly, but more than half of cases occur in individuals who are 10-20 years old.

Objective: Here, the objective was to search for protein markers to indicate resistance to cisplatin in osteosarcoma and provide a theoretical basis for the early and accurate use of cisplatin to treat osteosarcoma.

Modeling of sectionally continuous communication channel with inhomogeneously distributed tissues.

Background: This study aimed to investigate effects on the transmission channel caused by heterogeneous distribution in tissues and joint characteristics.

Method: Human arm section scans were taken using CT technology, and zoned, following which, a circumference measurement experiment was performed to analyze the effect of inhomogeneous distribution of tissues. In order to analyze the arm joint's effect on channel transmission, we proposed a piecewise modeling method in combination with connection conditions.

A numerical model for blast injury of human thorax based on digitized visible human.

Knowledge of the pressure distribution around human thorax in blast help to understand the injury mechanisms and their assessment. To investigate the transmission mechanism of the pressure on human thorax in blast, a three dimension surface model of human thorax was constructed in this work. To increase the precious of this model, tetrahedron element division method was applied to transfer the rough 3D surface model to hexahedral elements model.
