BACKGROUND Stroke rehabilitation with different exercise paradigms has been investigated, but which one is more effective in facilitating motor recovery and up-regulating brain neurotrophic factor (BDNF) after brain ischemia would be interesting to clinicians and patients. Voluntary exercise, forced exercise, and involuntary muscle movement caused by(More)
In some stroke rehabilitation programs, robotic systems have been used to aid the patient to train. In this study, a myoelectrically controlled robotic system with 1 degree-of-freedom was developed to assist elbow training in a horizontal plane with intention involvement for people after stroke. The system could provide continuous assistance in extension(More)
Cluster ensemble is one of the main branches in the ensemble learning area which is an important research focus in recent years. The objective of cluster ensemble is to combine multiple clustering solutions in a suitable way to improve the quality of the clustering result. In this paper, we design a new noise immune cluster ensemble framework named as(More)
Recent advances in SoC technology offer the possibility to realize the function of wireless sensor network node in a single chip. In this paper a reconfigurable wireless sensor network node for quick transmission of voice data is being described. Compared with existing works, we can implement different types of components depends on the application in which(More)
OBJECTIVE To investigate the variation of muscle coactivation patterns during the course of robot-assisted rehabilitation on elbow flexion and extension for chronic stroke. DESIGN A detailed electromyographic analysis was conducted on muscle activation levels and muscle coactivation patterns, represented by a cocontraction index of a muscle pair, for the(More)
OBJECTIVE To evaluate the joint angle dependence of brachialis muscle architecture at rest and changes in brachialis muscle architecture during isometric voluntary contractions in people after stroke. DESIGN The pennation angle and fascicle length of the brachialis muscle were measured in the affected and unaffected sides of people after stroke at 9(More)
Cancer class discovery using biomolecular data is one of the most important tasks for cancer diagnosis and treatment. Tumor clustering from gene expression data provides a new way to perform cancer class discovery. Most of the existing research works adopt single-clustering algorithms to perform tumor clustering is from biomolecular data that lack(More)
10-Hydroxycamptothecin (HCPT) loaded PLA microbubbles, used as an ultrasound-triggered drug delivery system, were fabricated by a double emulsion-solvent evaporation method. The obtained microbubbles were characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD), differential scanning calorimetry(More)
In recent decades, satellite-derived start of vegetation growing season (SOS) has advanced in many northern temperate and boreal regions. Both the magnitude of temperature increase and the sensitivity of the greenness phenology to temperature-the phenological change per unit temperature-can contribute the advancement. To determine the(More)
