OBJECTIVE Chronic subdural hematomas (CSDHs) are often found in neurosurgery, and display a recurrence rate of up to 37%. This study aimed to determine potential risk factors contributing to unilateral CSDH recurrence, and evaluate the role of postoperative management with dexamethasone (DX) in reducing recurrence. METHODS Between January 2010 and May(More)
This paper proposed a scheme of using rail-free multifunctional robot in onsite repair of hydraulic turbine blade for large-scale axial-flow and Francis runners. The robot processes such functions as profile detection and measurement, air-gouging cleaning, grinding, welding and so on. The robot's main body is composed of an all-position rail-free mobile(More)
At present, spherical tank manufacture is still staying at the level of manual welding or semi-automation. In order to improve quality of weld seam and guarantee safe operating of spherical tank, automatic welding equipment is needed urgently. A intelligent wheeled mobile robot equipped with CCD based visual sensor has been developed to acquire better weld(More)
This paper proposed a design idea of a novel under-actuated finger mechanism, and designed the finger mechanism. The finger has no actuator in itself, is only driven by the other finger joints and object grasped. The finger is similar to a human finger and can be easily arranged in series to realize a finger with super under-actuation and high integration.(More)
BACKGROUND Recent studies observed that altered energy metabolism has become widespread in cancer cells along with other cancer-associated traits that have been accepted as hallmarks of cancer. Akt signaling pathway is involved in the aerobic glycolysis program. However, mechanisms underlying the regulation of aerobic glycolysis and Akt activity in gliomas(More)
Humanoid robotic hand is one of most impressive research focus in robotics. There are two important requirements in robotic hands: on the one hand, a hand has a good humanoid appearance and sizes and can grasp almost all of common objects, on the other hand, the same hand is very simple in structure, very easy in control and very low in cost. Most of(More)
A large amount of e®ort has been devoted to design better under-actuated robot hands. The most widely adopted approaches include rigid coupled hands and self-adaptive hands. The objective of this research is to design a robot ̄nger which combines advantages of both ways and overcomes their disadvantages. The concept of coupling and self-adaptation (COSA)(More)
