—Blind source separation problem has recently received a great deal of attention in signal processing and unsupervised neural learning. In the current approaches, the additive noise is negligible so that it can be omitted from the consideration. To be applicable in realistic scenarios, blind source separation approaches should deal evenly with the presence(More)
This study was to classify the axis fracture complicated with adjacent segment instability and to explore its significance to surgical management. 42 patients (25 males and 17 females) with axis fractures with an average age of 44.14 years (range, 23 to 65) who received surgery between January 2006 and June 2012 were analyzed retrospectively.

Objective. To discuss the practical value of the cough test during the tension-free vaginal tape (TVT) procedure. Methods. In the first group, 41 patients of female stress incontinence received TVT operations which were performed according to the Ulmsten's method strictly, only that the stress of tape was adjusted in light of the cough test. In the second(More)
BACKGROUND At present, traumatic atlantoaxial dislocation or C2-3 instability complicating odontoid fractures remains rarely reported. The aim of this study was to further investigate the surgical treatment strategies and curative effects for odontoid fractures combined with instability of adjacent segments. METHODS This is a retrospective study of 12(More)
