A novel highly birefringent photonic band-gap fiber (PBGF) with the squeezed modified honeycomb cladding is proposed. The polarization properties of the PBGF are investigated by using a full-vector finite difference method. Numerical results reveal that the phase birefringence of the PBGF could reach the order of 10-2, which is nearly two order of magnitude higher than that of conventional PMFs. The...

To investigate the cervical spinal cord mapping on electrical stimulation at LI4 (Hegu) by using `Signal Enhancement by Extravascular water Protons' (SEEP) - fMRI, and to establish the response of acupoint-stimulation in spinal cord. Methods: Three healthy volunteers were underwent low-frequency electrical stimulation at LI4. Meanwhile, a single-shot fast spin-echo (SSFSE) sequence was used to perform...
To characterize the brain mapping on reinforcement acupuncture stimulation at ST36 (zusanli), and to discuss the mechanisms of acupuncture to treat diseases. Methods: fMRI was performed on 26 healthy Chinese student volunteers. Sixteen subjects were acupunctured at the acupoint ST36, while 10 others at sham-acupoint (lateral from ST36 about 3cm). The fMRI studies were performed using a gradient echo-EPI...

The purpose is to study motor cortex mapping in patients with mass lesions near primary motor and sensory cortices with BOLD-fMRI. 18 patients with mass lesions near primary motor and sensory cortices, and 8 healthy volunteers were investigated with fMRI using a 1.5 T GE Signa scanner. The specific task was repetitive selfpaced index finger to thumb opposition with a frequency of approximately 2 Hz...
