Improved artificial bee colony algorithm based gravity matching navigation method.

Gravity matching navigation algorithm is one of the key technologies for gravity aided inertial navigation systems. With the development of intelligent algorithms, the powerful search ability of the Artificial Bee Colony (ABC) algorithm makes it possible to be applied to the gravity matching navigation field. However, existing search mechanisms of basic ABC algorithms cannot meet the need for high accuracy in gravity aided navigation.

[Comparative observation on curative effects of stenosing tenovaginitis of flexor digitorum treated with acupuncture knife therapy and blocking therapy].

Objective: To compare the curative effects on stenosing tenovaginitis of flexor digitorum treated with acupuncture knife therapy and blocking therapy so as to explore the better method.

Methods: Three hundred and four cases were randomly divided into acupuncture knife therapy group (164 cases) and blocking therapy group (140 cases). In acupuncture knife therapy group, hooking and cutting were applied on the pressure points and scleromas with Ren's hooked acupuncture knife; routine blocking therapy was applied in blocking therapy group.
