BACKGROUND Although the majority of patients with cerebral venous sinus thrombosis (CVST) obtain an optimistic clinical outcome after heparin or warfarin treatment, there remains a subgroup of patients who do not respond to conventional anticoagulation treatment. These patients, especially younger people, as documented by hospital-based studies, have a high(More)
A new control algorithm based on potential function and behavior rules to effectively control the formation of a multiple autonomous underwater vehicle (AUV) system under uncertain environment and to make the formation effectively avoid obstacles is presented. Proper potential functions concerning with object, obstacle and the structure of the formation is(More)
Scutellaria barbata D. Don is widely used as a folk antitumor and anti-inflammatory agent in Asia. However, a simple and global quality control method for S. barbata was lacking. In this study, six phenolic compounds, including P-coumaric acid, scutellarin, apigenin 5-O-β-glucopyranoside, luteolin, apigenin and 4'-hydroxywogonin were obtained from S.(More)
Breast cancer is the most common type of malignant tumor in women. Recently, it has been shown that detection of breast cancer tumor cells outside the primitive tumor is an effective early diagnosis with great prognostic and clinical utility. For this purpose, we developed a signal-on fluorescence aptasensor for label-free, facile and sensitive detection of(More)
A formation path tracking controller for multiple robot system by sliding mode control method is introduced. The dynamic equation of robot is transformed into a relative moving equation between the leader robot and the follower robot and the drawback of structural singularity in the robot with nonholonomic constraints is overcome. The sliding mode control(More)
OBJECTIVE Patients with cerebral sinus and cortical venous thrombosis develop venous infarcts in approximately 50% of cases, resulting in serious clinical symptoms. An animal model is needed to further clarify the underlying mechanisms and consequences surrounding cerebral venous sinus thrombosis, particularly for severe ones. METHODS Adult male(More)
To design a reliable high-performance fight control system, an accurate model of the helicopter is required. While the movement of the helicopter is very complicated, it is very difficult to identify the complete model of helicopter by the traditional methods. In this paper, an identifying method based on improved evolutionary strategy is proposed. In this(More)
To seek a decoding scheme with good performance, low complexity and fast convergence, we present an improved parallel weighted bit flipping (IPWBF) algorithm for finite geometry low-density parity-check codes whose parity check matrix is of heavy row and column weights. In the IPWBF, a bit flipping (BF) function and two parallel BF criteria, all of which(More)
