Adaptive Information Sharing with Ontological Relevance Computation for Decentralized Self-Organization Systems.

Decentralization is a peculiar characteristic of self-organizing systems such as swarm intelligence systems, which function as complex collective responsive systems without central control and operates based on contextual local coordination among relatively simple individual systems. The decentralized particularity of self-organizing systems lies in their capacity to spontaneously respond to accommodate environmental changes in a cooperative manner without external control. However, if members cannot obtain observations of the state of the whole team and environment, they have to share their knowledge and policies with each other through communication in order to adapt to the environment appropriately.

[Advances in treatment of facial rejuvenation in the past ten years].

Facial aging is caused by several aspects involving skin, its deep soft tissue (fat, muscles, fascia ligaments, ), and bones. The skin presents deepen wrinkles, darker, drying, and roughness. Volume loss and sag caused by gravity can be seen in deep soft tissue.

[Crosslinking sodium hyaluronate gel with different ratio of molecular weight for subcutaneous injection: animal experimental study and clinical trials subcutaneous injection].

Objective: To investigate the biocompatibility and degradation rate of crosslinking sodium hyaluronate gel with different ratio of molecular weight, so as to choose the effective, safe and totally degraded hyaluronate gel for aesthetic injection.

Methods: (1) Compound colloid was formed by cross-linking the divinyl sulphone and sodium hyaluronate with different molecular weight (4 x 10(5), 8 x 10(5), 10 x 10(5), 12 x 10(5)). (2) Healthy level KM mice was randomly divided into two groups to receive hyaluronic acid gel or liquid injection.

[Clinical application of a retrograde nasolabial fold island flap based on the upper lip artery].

Objective: To explore a new method for enlarging the rotation range of the nasolabial fold flap.

Methods: We designed a retrograde nasolabial fold island flap pedicled with the upper lip artery for repairing facial defects. The anatomy of the upper lip and the vascular supply to the nasolabial skin were observed.
