The ensemble classifier plays a critical role in protein fold recognition. In this article, a novel hierarchical ensemble classifier named GAOEC (Genetic-Algorithm Optimized Ensemble Classifier) is presented and it can be constructed in the following steps. First, a novel optimized classifier named GAET-KNN (Genetic-Algorithm Evidence-Theoretic K Nearest(More)
We undertook a comparative study of magnetic resonance imaging (MRI) vertebral morphometry of thoracic vertebrae of girls with adolescent idiopathic thoracic scoliosis (AIS) and age and gender-matched normal subjects, in order to investigate abnormal differential growth of the anterior and posterior elements of the thoracic vertebrae in patients with(More)
STUDY DESIGN MR imaging and multiplanar reconstruction were used to evaluate relative length of the spinal cord to the vertebral column in adolescent idiopathic scoliosis (AIS). OBJECTIVES Ratio of spinal cord length to vertebral column length and position of the cerebellar tonsils were evaluated and correlated with somatosensory cortical evoked(More)
STUDY DESIGN A cross-sectional study of the balance control in adolescents with idiopathic scoliosis. OBJECTIVE.: To investigate the relationship among somatosensory function, balance control, and adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA Balance control requires the contribution of somatosensory, visual, and vestibular inputs.(More)
There is no generally accepted scientific theory for the causes of adolescent idiopathic scoliosis (AIS). As part of its mission to widen understanding of scoliosis etiology, the International Federated Body on Scoliosis Etiology (IBSE) introduced the electronic focus group (EFG) as a means of increasing debate on knowledge of important topics. This has(More)
Osteoporosis is a multifactorial skeletal disorder characterized by decreased bone mass and deteriorated microarchitecture that lead to increased risk of fracture. The disuse osteoporosis refers to bone mass decrements under conditions of decreased mechanical loading, including decreased ground force reaction, muscular contraction, and microgravity-related(More)
To investigate the effect of laser acupuncture (LA) on disuse changes in articular cartilage using ultrasound biomicroscopy (UBM), Eighteen rats were randomly divided into the control group (C), the tail-suspended group (T), and the tail-suspended with LA treatment group (L). During 28-day suspension period, group L were treated with LA at acupoints on the(More)
OBJECTIVE The phenomenon of foot binding, also known as 'lotus feet', has an enduring and influential history in China. To achieve a man-made smaller foot size, lifelong foot binding may have had adverse effects on the skeleton. We investigated bone properties in postmenopausal women with bound feet, which may provide new information for developing(More)
